ADJOURNMENT (449ateir THE JINTNiLA CE Of MINNESOTA HERITAGE PRESERVATION COMMISSION MEETING September 16, 2020 7:00 P.M. Chairwoman Mino called the meeting to order via Zoom at 7:02 p.m. Present: Chair Mino, Commissioners Finwall, Heimdahl, Krakowski, Larson, Thueson, Council Representative Junker Absent: Commissioner Walls Staff: City Planner Wittman APPROVAL OF MINUTES Possible approval of minutes of August 19, 2020 Meeting Motion by Commissioner Thueson, seconded by Commissioner Finwall, to approve the minutes of the August 19, 2020 meeting. All in favor. OPEN FORUM Tom Lynum, introduced himself and his wife Sandy Lynum, 626 North Fourth Street, owners of the William Sauntry Bed and Breakfast, and Judi and Marty Nora, 625 North Fifth Street, owners of the Alhambra (Sauntry Gymnasium). Mr. Lynum explained that since 1999 they have owned these iconic historic buildings which have been featured in many national architectural and historic preservation media. The Alhambra is known as one of the best examples of Moorish architecture in the U.S. Both properties have been for sale for some time. Prospective buyers have approached both owners about reuniting the properties to create a place for events, corporate functions, weddings and similar gatherings. There has been reticence on the part of City representatives they have talked to about this approach. They are seeking others who share their interest in the restoration, maintenance and sustainability of these properties. They are not asking for approval for a big event center or anything that would be detrimental to the residential neighborhood but would like the City to consider the parameters under which they could apply for a Special Use Permit to host small events. They welcome input from the HPC and also plan to talk to the Planning Commission. Councilmember Junker said he would be happy to help the owners communicate with the City. Chairwoman Mino pointed out that the HPC is focused on design, so if there were to be changes made to the physical structure, it would come before the HPC. Use -related changes are not under the HPC's purview. City Planner Wittman said she has talked with potential purchasers and with the property owners. Currently the City code does not allow for event centers in residential districts. She acknowledged this is a unique property but there would need to be some sort of code modification to allow the property owners to request a Special Use Permit to hold events. Staff has talked to the Council about State law which prohibits the granting of a use variance for a use that isn't allowed in that district unless a site is designated historic. This is one avenue for looking at how the code might be amended. Ms. Wittman acknowledged the Commission's interest in finding ways to maintain continued use of historic structures. Councilmember Junker cited a similar request about four years ago at the former church north of City Hall whose owners wanted to convert it to an event center. The request was denied by the City Council with the biggest objection being neighborhood parking concerns. Mr. Lynum said he doubts parking will be an issue as these two properties control essentially half the block. There is ample offstreet parking. Heritage Preservation Commission Meeting September 16, 2020 Commissioner Finwall commended the owners for maintaining the historic character of the home. As a neighbor, she would be concerned about parking but it sounds like that can be addressed. CONSENT AGENDA Case No. 2020-24: Consideration of a Design permit for an awning sign at 221 Main Street North in the Downtown Design Review District. River Market Coop. applicant. TREMAR LLC, property owner. Motion by Commissioner Finwall, seconded by Commissioner Krakowski, to adopt the Consent Agenda. All in favor. PUBLIC HEARING There were no public hearings. NEW BUSINESS Case No. 2020-23: Consideration of a Design Permit for exterior facade improvements and signage at 106 Main Street South in the Stillwater Commercial Historic District. Peter Hovland. applicant. RHR Investments LLC. property owner. City Planner Wittman explained that Hovland Academy proposes facade alterations involving painting and business signage. They have applied for a Design Permit for: 1) installation of trim boards on the flat, black facade; 2) painting of the all existing flat, black facade and newly -applied trim in Sherwin Williams "Rainstorm"; 3) installation of a 4.9 s.f. wood hanging sign to be painted red with the business logo; and 4) an approximately 20 s.f. projecting wood wall sign to be painted gray to read "Hovland Conservatory of Music" in white. They are proposing window signage less than one-third of the window area, which does not require design review. She noted for the record that inclusion of contact information in signage is generally discouraged. Staff recommends approval of the request with five conditions. Peter Hovland, applicant, explained the changes. The goal is to find ways to downplay the bank front look and make it look more Victorian. Chair Mino asked if the applicant has thought about opening up the window area for a more traditional look. Mr. Hovland replied that right now it is not feasible to open up the window area. They may be able to do a bigger project in their next five year lease. Commissioner Larson noted that the entrance and window are different heights and the trim calls attention to that. He suggested placing a single piece of trim across the building facade horizontally, where trims do not align at the door entrance, maybe with a wider piece below the door in order to get the window and door opening to align with trim in some way. Mr. Hovland said he could place one trim piece all the way across the door. He understands the issue. Commissioner Larson voiced concern that use of board and batten relies on caulk joint alone to prevent water from getting behind it. If flat panels are wood it could tend to pick up water and start to peel. Mr. Hovland replied that the trim will be wood, primed and painted all six sides prior to assembly and painted again on the base. If water gets through, it will go to the material that is there now. Motion by Commissioner Larson, seconded by Commissioner Krakowski, to approve Case No. 2020-23, Design Permit for exterior facade improvements and signage at 106 Main Street South, with the five staff - recommended conditions. All in favor. OLD BUSINESS Page 2 of 3 Heritage Preservation Commission Meeting September 16, 2020 There was no old business. OTHER DISCUSSION ITEMS Design Guideline Update Project Ms. Wittman stated that staff will start the Design Guideline update project this fall. MN SHPO Preserve Minnesota Conference Ms. Wittman and Commissioner Heimdahl said they attended a virtual session on real estate easements. FYI NAPC Forum Discussion and Attendance Reporting Ms. Wittman asked Commissioners who attended to please submit their attendance forms to her. Stillwater Lights Councilmember Junker reported that the Stillwater Lights Committee is trying to finalize the winter 2020- 2021 plan which includes temporary lights on the gazebo. He is not sure of the design yet. He would like to get comments from the HPC. Ms. Wittman stated she submitted comments to the Chamber with potential concerns about impacts on the historic structure of a temporary light show. More details may be forthcoming. Commissioner Larson said he was taken aback by the light show that was done on the gazebo last year. Because the gazebo is a historic structure, a different type of lighting, for instance ground lights, would be more appealing than moving animation on the structure. Chairwoman Mino agreed that the dignity of the building should be preserved. Lighting that enhances the building would be more appealing. Commissioner Finwall added that cool white lights should not be used. Preservation Ordinance Amendment Update Commissioner Thueson asked if the ordinance passed. Ms. Wittman said the Council adopted the ordinance and it will be published on Friday. ADJOURNMENT Motion by Commissioner Thueson, seconded by Commissioner Finwall, to adjourn. All in favor. The meeting was adjourned at 7:58 p.m. ATTEST: Abbi Wittman, City Planner Amy Mino, Chair Page 3 of 3 r wa ter T FkE 6-FI iH P� 4 F. F a M I N NS Sa T A PLANNING REPORT TO: Heritage Preservation Commission CASE NO.: 2020-27 REPORT DATE: October 14, 2020 MEETING DATE: October 21, 2020 APPLICANT: Buettner Real Estate LANDOWNER: Buettner Real Estate REQUEST: Consideration of a Design Permit for patio alteration, bathroom addition and new trash enclosure building LOCATION: 127/131 Main Street South DESIGNATION: Contributing DISTRICT: Stillwater Commercial Historic District Downtown Design Review District REPORT BY: Abbi Jo Wittman, City Planner INTRODUCTION Buettner Real Estate owns the structures at 127 Main (historically known as the Mosier Block) and 131 Main Street South (historically known as the Jarchow and York Block), both designated as contributing to the Stillwater Commercial Historic District. Leo's Grill and Malt Shop operates a patio off the backside of the building at 127 Main Street South, accessible from Chestnut Street and visible from Water Street. The owners would like to alter the patio design, add a bathroom to the back of the building, and construct a trash enclosure. Street View May, 2019 (© 2020 Google) The project is located in the Flood Fringe overlay district. As such, the accessory uses, structure, and structural addition require review by the City Planning Commission and Council for conformance to the City's Floodplain ordinance. 127 Main Street South HPC 2020-25 Page 2 of 5 SPECIFIC REQUEST The applicant is requesting approval of a Design Permit for: • The construction of a 10.5' wide by (approximately) 12' long red brick trash enclosure; and • Redesign of the patio to include elevated seating on a black metal and wood awning. The lower level seating is proposed to have polycarbonate wall panels in the winter; and • An accessible bathroom added Street View — May, 2019 (© 2020 Google) onto the exterior of the building but not accessible from within the building; and Installation of a 10' long by 2' tall sign to look identical to the business's existing sign on Chestnut Street East. The primary build out materials will be red brick, wood, and black metal. The concrete patio is proposed to be divided into three different sections. One area, adjacent to 308 Chestnut Street East, will be dedicated to a seasonal vendor and will allow for all patron cueing onsite. Another area would be for sit-down dining. The two areas are proposed to be separated with an irrigated planter with trellis to provide a living wall between the two different service areas. A portion of the at -grade patio dining will be roofed, providing for limited elevated dining. This roof structure will extend over a portion of the patio, building access and restaurant service areas, as well as the proposed bathroom. The roofed area will connect into the existing single -story addition on the back of the Jarchow and York Block at 127 Main Street South. Additionally, the accessible restroom on the back of the building will also be installed on the back of the one-story building. The new bathroom, to be constructed of red brick, will utilize the first-story's eastern wall as its interior wall; it will be roofed with the overhang for the elevated dining area. Utilities for the accessible toilet and sink are proposed to run through the exterior wall. This is proposed to be located in an area where the business has provided a porta-potty in the past. The third area will be reserved for the (approximately) 120 square foot trash enclosure. A roll - up, windowed garage door will be located on the eastern property line in an area where an existing wood fence and gate currently exist. The trash enclosure building will have an exterior light on the Water Street side. ANALYSIS As the property has been designated as a Heritage Preservation Site due to its significance within the Stillwater Commercial Historic District, the Commission must determine the alteration is compatible, it will not materially impair the structure, and that it will not alter the significance 127 Main Street South HPC 2020-25 Page 3 of 5 and integrity of the structure, other structures in the district, or the district itself. The Commission must consider conformance to the Secretary of the Interior's (SOI) Standards and Guidelines for Rehabilitation and Stillwater's Downtown Design Review District guidelines in making its decision. At -grade patio improvements and landscaping will not affect the essential character or form of either building, the patio or the surrounding area. However, the installation of a bathroom, trash enclosure building, roof overhang and elevated dining area will affect the overall look of the area. SOI Standards #9 and #10 specifically address additions and exterior alterations to structures and sites. '° 2 The standards do not encourage the destruction of historic material and encourage additions that, if removed, would not impact the essential form and integrity of the historic property. While historically there was a Z _° ❑ "XV. structure on the site (see the �It 1904 Sanborn Map, right), it r"� �~ appears there was an open e ! M -� -- t �OJr Ors courtyard between all buildings �!!

As the patio is proposed to be stepped towards the top of the trash enclosure and the two-story building to the 1 New additions, exterior alterations, or related new construction shall no destroy historic materials that characterize the property. The new work shall be differentiated from the old and shall be compatible with the massing, size, scale, and architectural features to protect the historic integrity of the property and its environment. (SOI #9) 2 New additions and adjacent or related new construction shall be undertaken in such a manner that if removed in the future, the essential form and integrity of the historic property and its environment would be unimpaired. (SOI #10) s The design of the building should help make the street enjoyable, visually interesting and comfortable. 127 Main Street South HPC 2020-25 Page 4 of 5 north, the design "break[s] up building masses into units of scale that relate to adjacent structures" which is "sympathetic to the proportion of their neighbors". 4 With no setback on the Water Street site, the design is supportive of guidelines and standards which encourage construction to the right-of-way edge. The flat awning, as well as the seasonal use of a polycarbonate wall panels to enclose some seating, is designed for protection from the elements; the shape and design conform to the review district's guidelines. The Downtown Design Review District Rear Entrances and Utility Areas and Mechanical Equipment Design Guidelines indicate rear fagade entrance should be clean and well maintained and present a welcome appearance. They encourage screening exterior trash and storage areas, using architectural elements, from view of nearby streets and adjacent structures in a manner that is compatible with the building and site design. The trash enclosure will be constructed of red brick similar to the primary fagade of the building. The Water Street side will contain a single, roll -up, windowed garage door. Though the guidelines do not encourage the use of heavily tinted glass', the glass should help screen the building's contents. The lighting fixture, integrated into the overall design, is down shielded. Adding a sign to the back of the property will also be a new feature. As the property fronts Water Street, it would be eligible for signage on this fagade. The size of the sign conforms to the zoning code requirements. Its dimensional nature is encouraged by the adopted guidelines though the sign is nearly identical to a sign that already fronts Chestnut Street East. However, since the sign is associated with a different building than Leo's Grill and Malt Shop, and is physically separated by 308 Chestnut Street East, it substantially conforms to the guidelines in place. ALTERNATIVES HPC has alternatives related to this request. A. Approve. If the proposed application meets the Downtown Design Review District standards, and the standards set forth for Site Alteration Permits, the HPC should move to approve Case No. 2020-25. Staff recommends the following conditions for approval: 1. Plans shall be consistent with those submitted to the Community Development Department and are on file with HPC Case No. 2020-25 unless modified by the conditions herein. 2. Lighting with exposed bulbs shall not exceed 3500K. 3. The polycarbonate panels shall be permitted for no greater than six months per year. 4. HPC Design Permit approval does not constitute building permit approval. A building permit shall be obtained prior to demolition. 5. All minor modifications to the plans shall be approved in advance by the City Planner. All major modifications shall be approved in advance by the HPC. Determination of the distinction between "major" and "minor" is defined in the Zoning Ordinance. B. Approve in part. 4 Downtown Design Review District Proportion Design Guideline 5 Downtown Design Review District Fagade Opening Design Guideline: For infill building, window frames should be wood, or appropriately colored aluminum or vinyl clad. Mirrored or heavily tinted glad on the first floor or street level should not be used because it conveyed a conflicting modern design feeling. 127 Main Street South HPC 2020-25 Page 5 of 5 C. Deny. If the HPC finds that the proposal is not consistent with the findings set forth for the granting of a Design Permit, then the Commission may deny the request. With a denial, the basis of action is required to be given. Furthermore, a denial with prejudice would prohibit the applicant from resubmittal of a similar application for one year. D. Table. If the HPC needs additional information to make a decision, the request may be tabled to the following hearing. FINDINGS AND RECOMMENDATION The patio's new design will change the feel of this (mostly) at -grade open space. However, the chosen design is intended to more conform to the guidelines in place and to highlight the pedestrian experience. Staff finds that, with certain conditions, the project is compatible with, and will ensure continued significance and integrity of, all properties within the historic district. Therefore, recommends conditional approval of HPC Case. No. 2020-25 with the conditions outlined in Alternative A.

The current wooden fence and trash enclosure are nearing the end of their life span. Those structures were put in service approximately 20 years ago and the condition of them is poor. For the past 12 years, Leo's has offered the use of a Porta Potty to its guest during the Summer months. Although it is better than no restroom, we would like to better accommodate our guests. The proposed changes include removing the wooden fence and garbage enclosure along with removing the black metal fence and concrete pad. Our plans include constructing a brick building as a trash enclosure. The building will help reduce the smell of trash as well as being more visually attractive than what is in place. Our plans also include the construction on a full -service restroom (ADA compliant) with running water and flushing toilet. With the Chestnut Street Plaza on the horizon we feel that an attractive dining area at Leo's will be inviting to our guests. We are proposing an awning area with dining area under it as well as dining on the second level. This will offer our guests a unique view of the St. Croix River Valley.

These demountable panels would be rigid, clear polycarbonite panels put up to maintain the views for the customers, but also protect them from the elements and maintain a warmer environment with radiant floor heating. These panels would be designed to have a minimum visual impact with slimline framing, provide appropriate coded egress, and removed in the months that they are not needed. We are seeing restaurants get creative during these times to create outdoor spaces for customers while maintaining comfortable distances. We are also proposing to have seasonal lounge seating on the patio with gas fireplaces that will be stubbed and removed when the patio converts back to served seating. 1 1 P a g e Examples 3D Models — Exhibit A i 3 1 P a g e V.1 4 %01.

Often referred to as the Mount Vernon of the West, it was designed by architect William M. Ingemann. This is a reinforced concrete and steel structure faced in 102 2nd Street North HPC 2020-26 Page 2 of 4 brown brick with Federal -style end chimneys and a gabled asphalt shingle roof. It has a 13- coulmn, two-story, shed -roofed projecting wood portion on the front facade. The property is designated as Contributing to the Stillwater Commercial Historic District. In April, 1976 the City approved Planning Case No. 273 which allowed the addition of a mobile home and outdoor cooking area on the south side of the building. Building Permit No. 4160, issued in June, 1977, approved the moving of a wood frame building on the south side. Onsite investigation has determined a steel semi bed with a wooden structure on top was backed into the site, slightly offset from the south wall. The entire mobile portion was sided around. It appears the only portion of the addition that touches the original walls is the metal flashing around at the one-story area's roofline. Additionally, original hotel/commercial door openings were utilized as access points from the hotel into the addition. The 1992 Stillwater Commercial Historic District National Register of Historic Place nomination form notes some lateral windows on the south and north side have been infilled or altered with brick infill. The nomination notes is an attached one-story addition on the north side. However, City records approved an addition on the south side of the structure. Owners of the Lowell Inn would like to remove portions of the non -historic elements on the south (Myrtle Street facing) side of the Lowell Inn and restore portions of the exterior (street facing) facade back to its original design. The project is proposed to be completed in two phases. REQUEST The applicant is requesting approval of a Design Permit for the selective removal of the following components on the north elevation: • The multi -sided wood and window corner feature; and Approximately 40' of the single - story, 10' addition. The area of proposed demolition is shown in yellow to the right. Once demolition has occurred, the property owner would like to seek City approval to restore the south side of the building to its original state. ANALYSIS Street View — May, 2019 (© 2020 Google) As the property has been designated as a Heritage Preservation Site due to its significance within the Stillwater Commercial Historic District, the Commission must determine the alteration is compatible, it will not materially impair the structure, and that it will not alter the significance and integrity of the structure, other structures in the district, or the district itself. The Commission must consider conformance to the Secretary of the Interior's (SOI) Standards and 102 2nd Street North HPC 2020-26 Page 3 of 4 Guidelines for Rehabilitation and Stillwater's Downtown Design Review District guidelines in making its decision. Applicable SOI Standards' suggest this one-story addition should not have been added in this location on this structure. As noted, investigation of the addition implies historic material may only have been covered and that detailing and trim may be the only material physically removed.2 Since the original nomination notes the one-story addition, question can be raised as to whether or not the addition has acquired its own significance but this portion of the building is not at least 50 years old and does not contribute to the integrity of the building. As it does not contribute to the character of the building and removal will not destroy historic material, demolition of a portion of the first story addition is appropriate. The first phase demolition will allow the owner to understand what is needed to return the fagade to its original character.3 The intent of the owner is to retain and preserve the historic character of the building, conforming the SOI standards and adopted design guidelines 4. During demolition portion, any architectural features uncovered should not be removed or altered unless it is absolutely necessary to allow restoration where appropriate and feasible5. Fagade reconstruction is proposed to occur in the spring of 2021. During this time, all exposed openings must be sealed. Utilizing blank doors for temporary (< six months) sealing is appropriate. Until demolition has occurred, it will be unclear as to what is needed to close up the window openings currently covered with artwork on the inside of the building. The owner is working with a licensed architect on the reconstruction plans which will need to be submitted to the HPC for review and approval prior to construction. Plans for exterior fagade improvements should be substantially similar to the exterior of the structure in the 1920s. Where detailing has already been removed, every effort should be made to replicate them5. ALTERNATIVES HPC has alternatives related to this request. A. Approve. If the proposed application meets the Downtown Design Review District standards, and the standards set forth for Site Alteration Permits, the HPC should move to approve Case No. 2020-26. Staff recommends the following conditions for approval: 1. Plans shall be consistent with those submitted to the Community Development Department and are on file with HPC Case No. 2020-26 unless modified by the conditions herein. ' New additions and adjacent or related new construction shall be undertaken in such a manner that if removed in the future, the essential form and integrity of the historic property and its environment would be unimpaired. (SOI # 10) 2 New additions, exterior alterations, or related new construction shall no destroy historic materials that characterize the property. The new work shall be differentiated from the old and shall be compatible with the massing, size, scale, and architectural features to protect the historic integrity of the property and its environment. (SOI #9) s Downtown Design Review District Fagade Opening Design Guideline 4 The historic character of a property shall be retained and preserved.

LANDOWNER: Richard Farrell of White Bear Ventures LLC REQUEST: Consideration of a Design Permit for rooftop improvements LOCATION: 223 Main Street South DESIGNATION: Contributing DISTRICT: Stillwater Commercial Historic District Downtown Design Review District REPORT BY: Abbi Jo Wittman, City Planner Main Street View — May, 2019 (© 2020 Google) Water Street View — May, 2019 (© 2020 Google) 223 Main Street South HPC 2020-27 Page 2 of 4 INTRODUCTION Richard Farell of White Bear Ventures LLC is renovating the third story of the building at 223 Main Street South into a single family residence. As part of the project, the owner would like to remove the existing elevator bulkhead and a stairwell access from the roof. The project includes reconstructing the elevator access directly adjacent to an existing skylight that exists near the northwest corner of the building. This skylight lights a three-story stairwell that would be extended to the roof. In addition to these improvements, the owner would like to add a 224 square foot area for storage. The elevator access from the third floor to the roof and the enclosed storage area will require a variance from the City's Planning Commission. To the date of memo development, no variance request has been submitted. SPECIFIC REQUEST The applicant is requesting approval of a Design Permit for: • The demolition of existing rooftop stairwell and elevator bulkhead (shown in red, below); and • Construct a new elevator bulkhead adjacent to an existing rooftop skylight (shown in green, below); and • Add a 224 square feet enclosure onto the stairwell access and elevator bulkhead. The stairwell access, elevator bulkhead, and 224 square foot enclosed area is proposed to be sided in corrugated metal like the existing rooftop protrusions. ANALYSIS As the property has been designated as a Heritage Preservation Site due to its significance within the Stillwater Commercial Historic District, the Commission must determine the alteration is compatible, it will not materially impair the structure, and that it will not alter the significance and integrity of the structure, other structures in the district, or the district itself. The Commission must consider conformance to the Secretary of the Interior's (SOI) Standards and Guidelines for Rehabilitation and Stillwater's Downtown Design Review District guidelines in making its decision. 223 Main Street South HPC 2020-27 Page 3 of 4 SOI Standards #9 and #10 pertaining to the removal of material and the compatibility of additions are most relevant. 1,2 The removal of non -historic material from the rooftop is and adding a new access is appropriate. Concentrating the area of rooftop improvements is also appropriate. The placement of the new stairwell in an area where stairwell exists from ground level and an existing rooftop opening already exists is appropriate. However, this area is closer to the Main Street right-of-way. When viewing the structure of the corner of Chestnut and Main, the improvement will be noticeable. The SOI Standard #9 specifically states new additions must be "compatible with the massing, size, scale, and architectural features to protect the historic integrity of the property and its environment". As this is a three-story structure, the rooftop improvements will be noticeable visible from the Chestnut and Main Street right-of-ways. Plans show the improvements set back from the parapet edge by approximately 13 % this will allow for the continued view of the structure's chimney, visible in the photograph to the right. The chimney measures approximately 14.5' from the roof whereas the elevator bulkhead measures approximately 14' from the roof. The elevator bulkhead (since it is not providing accessibility for the entire structure) is not outright permitted. A code compliant stairwell access is permitted in the code; the installation of the stairwell access, measuring 10' from the roof, is necessary for rooftop access. However, the height (size) of the structure is above minimum code requirements (of 8'6" at the top of stair). This, coupled with the elevator bulkhead height and additional enclosed area greater a significant mass that will be visible from the Main and Chestnut Street right-of-ways. While the improvement will not be greater in size than the chimney, its mass will draw attention away from the historical rooftop I New additions, exterior alterations, or related new construction shall no destroy historic materials that characterize the property. The new work shall be differentiated from the old and shall be compatible with the massing, size, scale, and architectural features to protect the historic integrity of the property and its environment. (SOI #9) 2 New additions and adjacent or related new construction shall be undertaken in such a manner that if removed in the future, the essential form and integrity of the historic property and its environment would be unimpaired. (SOI #10) 223 Main Street South HPC 2020-27 Page 4 of 4 architectural feature. The chosen design material, too, could draw attention to this improvement. Traditionally rooftop improvements have been encouraged to be darker, more subdued. ALTERNATIVES HPC has alternatives related to this request. A. Approve. If the proposed application meets the Downtown Design Review District standards, and the standards set forth for Site Alteration Permits, the HPC should move to approve Case No. 2020-27. Staff recommends the following conditions for approval: 1. Plans shall be consistent with those submitted to the Community Development Department and are on file with HPC Case No. 2020-27 unless modified by the conditions herein. 2. All minor modifications to the plans shall be approved in advance by the City Planner. All major modifications shall be approved in advance by the HPC. Determination of the distinction between "major" and "minor" is defined in the Zoning Ordinance. B. Approve in part. C. Deny. If the HPC finds that the proposal is not consistent with the findings set forth for the granting of a Design Permit, then the Commission may deny the request. With a denial, the basis of action is required to be given. Furthermore, a denial with prejudice would prohibit the applicant from resubmittal of a similar application for one year. D. Table. If the HPC needs additional information to make a decision, the request may be tabled to the following hearing. FINDINGS AND RECOMMENDATION The addition of a minimum code -compliant stairwell on the rooftop in an area of an existing opening and that will tie into the three-story stairwell is appropriate. However, the 10' tall stairwell, in combination with the 14' elevator bulkhead, and the 224 square foot addition of enclosure is not compatible with the structure and its surroundings. While it will not materially impair the structure as all improvements could be removed in the future and the structure would remain as it sits today, it does affect the structure's integrity and the integrity of the district given it will rise above any other structure on this block. Staff recommends denial of HPC Case. No. 2020-27 and encourages the HPC to discuss the proposed design and potential design alternatives with the applicant and/or property owner.

This building is believed to have been built in the 1880's. This is a three-story red brick Classical Revival style commercial building with Red sandstone trim and sandstone banding between second and third floors. It is topped by an elaborate broad metal paired bracketed and paneled swag parapet with dentils. Second and third story windows are newer, original opening still intact. The store front is altered with newer brick and clapboard in the Transom above main entrance. This building is mixed use with a Bakery currently operating out of the 1st floor space. 2nd and 3rd floors are residential and will be owner occupied. The proposed changes include: - Moving the 3rd floor to roof stair access from the middle of the space on 3rd floor to the existing stairwell located at the Northwest end of the building. - Moving the existing Elevator from the current location and putting it next to the existing stairwell at the Northwest end of the building. (Existing elevator cannot be brought up to code) - Adding a "Covered Vestibule/Storage" approximately 324 square feet to receive the elevator stop at the roof, also receive the relocated stairway to the roof from 3rd. This space will provide a covered entrance to the roof, house the elevator and stairway, as well as provide storage space for furniture used on the existing deck. - This structure will be comprised of the same material currently being used for the existing Stairway Doghouse as well as the existing Elevator Doghouse. o Corrugated galvanized steel siding o Aluminum soffit and fascia o Windows along the West and South side of the Structure. Tri fold glass doors on the East side. Please see sheet A7.1 of attached Architectural drawings for the details - This structure is designed to have a flat EPDM roof to minimize the overall height. As the roof sits right now the existing stair and elevator doghouses are not contributing to the historical look of the building. These were installed years after the initial construction of the building. The original elevator shaft location is where we intend to put the new elevator bringing it back to its original location in the building. We believe that these additions that are scattered on the roof are not physically appealing as it currently sits. Our intention is to remove those later additions making for a cleaner organized look going from three structures to one. Please see the attached Architectural drawings for the exact location and look of the proposed structure. Thank you for your time and consideration in this matter.

Since that time, the City's design around the Dock Cafe has changed. The City submitted the amended plans to the State Historic Preservation Offices (SHPO) for their review. A copy of their review letter is attached. While some of the comments merely request submittal of additional materials and/or specification or treatment clarification, the SHPO does not agree with the City's findings the river overlooks are compatible with the historic character of either the Cultural Landscape District or the Archaeological district. City staff, along with consulting engineers, preservationists, and archaeologists are preparing materials for discussion with and resubmittal to the SHPO. City staff is bringing this back before the HPC for discussion. SPECIFIC REQUEST Review and discussion of: HPC Case no. 2019-16 Page 2 1. Design alteration around the Dock Caf6; and 2. SHPO comment letter The design around the Dock Caf6 has not significantly changed. The original designs (shown right), include a solider pile wall with precast concrete panels, a 6" curb, concrete trail and then rip rap and vegetation towards the Dock Caf6 patio wall. Instead of rip rap along the western side of the trail, a wall is proposed; see cross section attached. The wall is designed to help retain private land, providing physical separation between the public trail and private land. The new wall will be solider piled with concrete panels. The design of the wall is not proposed to be changed from the HPC's original wall review/approval. ANALYSIS The HPC must use the Secretary of the Interior's Standards for review of projects within these two eligible districts. The following applicable standards should be considered: ■ Every reasonable effort shall be made to provide a compatible use for a property which requires minimal alteration of the building, structure or site and its environment or to use a property for its originally intended purposes. ■ The distinguishing original qualities or character of a building, structure or site and its environment shall not be destroyed. The removal or alteration of any historic material or distinctive architectural features must be avoided when possible. ■ All buildings, structures and sites shall be recognized as products of their own time. Alterations that have no historical basis and which seek to create an earlier appearance shall be discouraged. ■ Changes, which may have taken place in the course of time, are evidence of the history and development of a building, structure or site and its environment. These changes may have acquired significance in their own right and this significance shall be recognized and respected. ■ Contemporary design for alterations and additions shall not be discouraged when such alterations and additions do not destroy significant historical, architectural or cultural HPC Case no. 2019-16 Page 3 material and such design is compatible with the size, scale, color, material and character of the property, neighborhood or environment. The installation of this wall, set back from the river, will have minimal to no change to the previously approved design. The impact may be less intrusive given the formally -proposed railing is no longer necessary in this location. Traditionally, city staff would have viewed this a minor change and authorized it without bringing the matter back before the HPC so long as the new design's wall surface texture matched the existing levee wall texture, as conditioned by the HPC. The SHPO's primary concern are the overlooks as there is "is certainly no precedent for such a massive and blocky structures protruding out from the edge of the shoreline". However, the City asserts that this area of shoreline would have had significantly sized and blocky features extending from the shoreline; this was documented in the City's historical and cultural resource assessment prepared by landscape research, also attached. City staff have scheduled a meeting with the SHPO to discuss the design alternated considered to see if there is an amended design that can be achieved. Staff will present designs considered to the HPC at the meeting for discussion and comment. POSSIBLE ACTIONS Staff is requesting the HPC review the design alteration around the Dock Cafe and discuss HPC comments, specifically pertaining to the overlook platforms. FINDINGS AND RECOMMENDATION The site of the proposed Riverbank Stabilization and Riverwalk work is well documented and has been significantly surveyed over the last several decades. The proposed project will be in conformance with previously approved plans and existing site conditions. The installation will not negatively impact historical, cultural and archaeological resources. Therefore, staff recommends conditional approval.

Information received in our office via e-mail on August 6, 2020 has been reviewed by our office pursuant to Section 106 of the National Historic Preservation Act (54 U.S.C. § 306108) and its implementing federal regulations, "Protection of Historic Properties" (36 CFR Part 800). By notification to our office dated February 10, 2020 we understand that the City of Stillwater (City) has been authorized by the St. Paul District, U.S. Army Corps of Engineers (USACE) to act on behalf of the federal agency and initiate Section 106 consultation with our office and others regarding the proposed federal undertaking and its potential effects on historic properties. We have completed a review of your letter dated August 6, 2020, a submission which included the following documentation in support of the City's "No Adverse Effect" Section 106 finding: • Project design plan set (61 sheets) titled St. Croix River Riverbank Stabilization and Riverwalk City Project #2016-06, Stillwater, MN (AMI Consulting Engineers, dated 7/23/2020); • Draft report titled Assessment of Effects for the Riverbank Stabilization and Riverwalk Project, Stillwater, Washington County, Minnesota (Report) dated 7/10/2020, as prepared by Landscape Research LLC and Two Pines Resource Group LLC; and • Stillwater Heritage Preservation Commission (HPC) agenda/packets and minutes for the July 17 and August 21, 2019 meetings during which the Riverbank Stabilization and Riverwalk Project was discussed; and • Stillwater HPC approval letter for the Riverbank Stabilization and Riverwalk Project, with conditions, dated October 23, 2019. Define Undertaking and Area of Potential Effects We understand by your August 6th letter that the proposed Stillwater Riverbank Stabilization and Riverwalk Project (Project), which we assume will require a permit from the USACE, will stabilize eroding banks of the St. Croix River south of Lowell Park and will also involve construction of a new 10 foot wide, pedestrian walkway with river overlook platforms in three (3) locations. As such, the riverbank stabilization, new pedestrian walkway and overlooks constitutes the federal undertaking subject to review under Section 106. The extensive Project description narrative and associated images, including current conditions and proposed Project renderings, as provided in Section 5.0 of the Report was helpful in our review. Based upon our understanding of the scope and nature of the federal undertaking, we agree that your definition of the Area of Potential Effect (APE) as described in narrative in your August 61h letter and pages 3-4 of the Report, and as documented on Figure 1: Project Location of the Report, is generally appropriate to take into account the potential direct MINNESOTA STATE HISTORIC PRESERVATION OFFICE 50 Sherburne Avenue Administration Building 203 ■ Saint Paul, Minnesota 55155 ■ 651-201-3287 mn.gov/admin/shpo mnshpo@state.mn.us AN EQUAL OPPORTUNITY AND SERVICE PROVIDER and indirect effects of the proposed undertaking. As the undertakings' scope and design is further defined, or if it is significantly altered from the current scope/design, then additional consultation with our office may be necessary in order to revise the current APE. Identification of Historic Properties We agree with the City's determination that recent surveys and evaluations completed for the St. Croix River Crossing Project, all of which has been completed within this undertaking's APE as well, meet contemporary standards and no additional survey work is warranted for this undertaking, as it is currently proposed. We agree with the City's identification of the following eight (8) historic properties, which are currently listed in the National Register of Historic Places (NRHP), as being located within the APE: • Moritz Bergstein Shoddy Mill and Warehouse • Stillwater Commercial Historic District (Commercial District) • Stillwater Lift Bridge • Washington County Courthouse • Jassay Block • Chicago, Milwaukee & St. Paul Depot/Freight House • Mortimer Webster House • Roscoe Hersey House We also agree with the City's identification of the following five (5) historic properties, determined eligible for listing in the NRHP through previous federal review and consultation, as being located within the APE: • Stillwater Cultural Landscape District (Landscape District) • Stillwater South Main Street Archaeological District (Archaeological District) • Hersey & Bean Sawmill/21WA0091 (also contributing to the Archaeological and Landscape Districts) • Hersey & Bean Planing Mill/21WA0092 (also contributing to the Archaeological and Landscape Districts) • Slab Alley/21WA0100 (also contributing to the Archaeological and Landscape Districts) We appreciate the inclusion of the additional historic context and documentation, including Sanborn map and photo documentation, in Section 4.0 and 7.0 of the Report. This was helpful in our review. Assessment of Adverse Effect Based upon information provided to our office at this time, we do not agree with the City's finding that the undertaking, as it is currently proposed, will avoid adverse effects to historic properties identified within the APE. Our reasons for this disagreement are provided below. Typically, for an undertaking such as this, which involves proposed modifications/alterations within historic districts and directly adjacent to individual historic properties, in order to avoid potential adverse effects specified under 36 CFR 800.5(a)(1) it must be designed consistent with the Secretary of the Interior's Standards for the Treatment of Historic Properties (Standards), specifically the Standards for Rehabilitation which allow for alterations to a historic property while preserving the property's historic characteristics which qualify it for listing in the NRHP. We acknowledge the fact that there are several, unique historic property types, including historic districts and individual properties, within the APE for this undertaking and each of these historic properties as differing areas of significance. This presents a challenge when applying the Standards. As supported in the accompanying effects assessment Report, under both the architecture/history and archaeology sections, the overall historic character of undertaking's construction area (subset of the APE) is described as having extensive modification through repeating episodes of filling and grading in order to accommodate several decades of industrial use. This existing topography, although currently a more vegetative parklike state, is a character -defining feature of the Archaeological District and the Landscape District. As such, consistency with the Standards for Rehabilitation of cultural landscapes and the associated Guidelines for the Treatment of Cultural Landscapes (Guidelines) are an appropriate application, and we have used these Standards and Guidelines in our evaluation of the City's effect assessment and finding for this undertaking. Riverbank between Nelson Street East and St. Croix Boat And Packet Company Marina. Please provide clarification regarding the proposed work from the southern edge of the Levee Wall at East Nelson Street to just past the Dock Cafe property, as the information provided to our office in the August 6th submission is inconsistent. The City's August 6th letter, the renderings and plans (dated 7/11/2019), specifically Sheet C2.1, from the 8/21/2019 HPC meeting, and the project description in Section 5.1.1. of the Report indicate that this segment of the undertaking involves construction of a steel I-beam and precast concrete panel wall on the riverside of the 10' walkway, with riprap placed up to the wall and landside between the walkway and the Dock Cafe deck. In the 7/23/2020 plans, specifically Sheet C2.1, we see that this same area is proposed to be riprapped from the water up to the edge of the walkway and a 5' retaining wall constructed on the landside of the walkway. Sheet C.6 of the 7/23/2020 plans shows the cross-section of the proposed 5' landside retaining wall at Stations 0+90, 1+100, and 1+50. Please clarify what is currently proposed for this segment of the undertaking as we have concerns regarding the appropriateness of both proposals per the Standards and Guidelines. This segment is directly adjacent to historic properties, especially Lowell Park, with differing historic significance and character -defining features related to formal landscape design and not former industrial use. Moritz Bergstein Shoddy Mill and Warehouse. We note that measures for protection of this historic property during construction have been integrated into current plans for the undertaking. This is consistent with the Standards and will avoid adverse effects to the historic property. Riverbank Stabilization. We generally agree that "building up" and creating a more uniform edge to the eroding riverbank may be considered consistent with the historic character of the undertaking's construction area. In order to meet Standards, it must be compatible with the materials, features, size, scale, and massing of historic features and landscape characteristics. We understand by the current plans and descriptions, that combination of riprap and soil filled riprap will be utilized to stabilize the riverbank, and the riprap type specified is "New MnDOT Class 5 Riprap" which includes fairly uniform and substantially sized stone materials. We have been provided no indication of the type of stone which will be used in this application and we recommend that it be consistent with types of stone, and in varying sizes, which would be found in and directly adjacent to the St. Croix River as these were likely the types of materials used to build up this area during the industrial era. Please provide documentation in support of this recommendation. Riverwalk Trail and Overlooks. As with the proposed riverbank stabilization methods discussed above, we generally agree that the proposed size, location, and alignment of the 10' bituminous Riverwalk Trail is compatible with the historic character of the undertaking's construction area and the design of the new feature is consistent with the Standards. However, we disagree with the finding that the 3 overlooks, currently proposed at 20' square, solid, concrete, bulkhead -type structures (for which we have not been provided elevation, cross-section, or detail drawings) are not compatible with the historic character of the Archaeological District or Landscape District and therefore do not meet Standards. While we understand that there may have been many docks and sidings in this area during the industrial era, there is certainly no precedent for such a massive and blocky structures protruding out from the edge of the shoreline. In order to avoid adverse effects, we recommend that the design of these overlooks be modified to minimize the structures as much as possible and design them to be more compatible with the historic character of the two historic districts. Perhaps the overlooks can be designed to be more fully integrated into the linear nature of the Riverwalk trail by creating a wayside, or pull -off, which may be longer but of much less depth. Essentially, without creating a false sense of history, these overlooks could be designed consistent with the footprint and alignment of a rail siding or a long, linear (yet shallower in depth) dock. Alternatively, the overlooks may be designed to be less blocky, perhaps as a cantilever platform, but still of minimal size. Please consider this recommendation to modify the designs of the overlooks in order to be compatible with the character of historic districts and conform with the Standards. Archaeology. We agree that direct effects to archaeological sites and features appear to be avoided through careful planning and design of the Project, as indicated in the Report. Although this is not mentioned in the City's August 6th letter, we agree with the conditions of the HPC approval and the recommendations on page 45 of the Report which specify protection of historic properties and features during construction. As with the Moritz Bergstein Shoddy Mill, all extant historic properties and features within and directly adjacent to construction limits should be clearly identified for avoidance and provisions for installation of protection measures, such as temporary fencing, included in the plans and specifications. Please provide documentation that the City will incorporate these protection measures, as well as any provisions for the development and implementation of an unanticipated discovery plan for the entire project, as recommended in the HPC's 10/23/2019 approval, and/or vibration monitoring plan at Overlook #2 and Overlook #3, which are directly adjacent to Office/Store Foundations of 21WA0091 and the Planing Mill's Powerhouse of 21WA0092, as recommended on pp. 45-47 of the Report. Effects Assessment. The City's August 6t" letter and the Report present findings of effect, an overall "No Adverse Effect" finding for the undertaking primarily as it relates to the three historic districts and some, but not all, of the individual NRHP-listed and NRHP-eligible historic properties identified with the APE. Please provide clarification regarding the City's finding of effect for all historic properties within the APE, as summarized above, even if it has been determined that the undertaking will have no effect on them. Per 36 CFR 800.5, the City will need to continue to consult with our office in an effort to resolve our office's disagreement with the "No Adverse Effect" finding for the federal undertaking. Consulting Party Engagement/Public Participation We appreciate the extensive documentation as it pertains to the City's consultation with the Stillwater HPC during project planning and design. Since our office has presented a disagreement with the City's finding of effect, and it appears as though the Project plans have been modified since HPC approval, we recommend that you re-engage the HPC in any future Section 106 consultation with our office. Finally, please provide clarification as it pertains to public notification and/or participation in the Section 106 review process as it was not clear in August 6t" documentation whether the public had been provided the opportunity to consider and provide comment/input on the federal undertaking and its effects on historic properties as required under 36 CFR 800.2(d). Please contact me at (651) 201-3290 or sarah.beimers@state.mn.us if you have any questions regarding our review of this project or would like to set up a meeting to discuss the comments provided in this letter. Sincerely, Sarah J. Beimers Environmental Review Program Manager cc via email: Abbi Wittman, City Planner, City of Stillwater Nancy Komulainen-Dillenberg, USACE ASSESSMENT OF EFFECTS FOR THE RIVERBANK STABILIZATION AND RIVERWALK PROJECT, STILLWATER, WASHINGTON COUNTY, MINNESOTA Architecture/History Report Prepared by: Carole S. Zellie, M.S., M.A. Principal Investigator Landscape Research, LLC 765 Hampden Avenue #315 Saint Paul, Minnesota 55114 Archaeological Report Prepared by: Michelle M. Terrell, Ph.D., RPA Principal Investigator Two Pines Resource Group, LLC 17711 260tn Street, Shafer, MN 55074 DRAFT July 10, 2020 MANAGEMENT SUMMARY The City of Stillwater, in Washington County, Minnesota, proposes to conduct a riverbank restoration project between the southern boundary of the City of Stillwater north to the southern edge of the Army Corps of Engineers floodwall at Nelson Street E. (immediately east of the Dock Cafe at 425 Nelson Street E.). The project's eastern boundary is the St. Croix River (Lake St. Croix). The western boundary is the St. Croix River Crossing Lower Loop Trail (Loop Trail) completed in 2015 by the Minnesota Department of Transportation. The purpose of the St. Croix Riverwalk and Stabilization Project is to stabilize the shoreline while at the same time separating users for pedestrian safety in an area where there is significant pedestrian, cyclist, and vehicular congestion. Riprap fill and vegetation will be installed along the length of the shoreline, and a 10'-wide concrete walkway will be constructed. The walkway will extend for approximately three- quarters of a mile south of Nelson Street E. Existing shoreline trees and vegetation will be removed and replaced with new trees and vegetation. At the northern end of the project area, immediately south of Nelson Street E., the existing sidewalk will be modifed and extended along a new wall constructed in front of the Dock Cafe. To the south, three nearly identical steel H-pile and concrete overlook platforms will be constructed adjacent to the river and will be accessed from the existing Lower Loop Trail via new walkway. One overlook will attach to the St. Croix Boat and Packet Company gangways. Two other overlooks to the south are located within Bridgeview Park. The project work areas will be accessed by a haul road utilizing the existing bituminous -paved Loop Trail. From May to July 2020, Landscape Research LLC (Landscape Research) and Two Pines Resource Group, LLC (Two Pines) conducted an investigation of historic and cultural resources for the project. This work was conducted for the City of Stillwater. The project requires a Clean Water Act Section 404 permit and therefore must comply with Section 106 of the National Historic Preservation Act (NHPA) of 1969, as amended, and the National Environmental Policy Act (NEPA) of 1969. The purpose of this investigation was to provide an assessment of the National Register of Historic Places (NRHP)-listed and determined eligible historic and cultural resources within the project Area of Potential Effect (APE) and to determine the effect of the proposed project construction on the resources. The APE includes properties within the Stillwater Cultural Landscape District, Stillwater Commercial Historic District and the Stillwater South Main Street Archaeological District, as well as other individually NRHP-listed properties. Based on review of historical documents, previous studies, proposed project plans, and fieldwork, the project as proposed, including new wall, overlook and concrete walkway construction, and shoreline riprap and fill installation, will not have an adverse effect on architectural and historical resources within the Stillwater Cultural Landscape District and Stillwater Commercial Historic District. Direct effects from new construction are limited to the Lake St. Croix shoreline where they will occur in areas of introduced fill and proposed overlooks are of a simple concrete and steel design. Indirect visual effects from key sightlines, including those from the Stillwater Lift Bridge (NRHP) and the Washington County Courthouse (NRHP), do not impact the Districts' qualities of location, setting, feeling, or association. The project as proposed will not have a direct effect on archaeological resources within the Stillwater South Main Street Archaeological District because planned activities will occur in areas of introduced fill. Further, beyond the District, the project area has a low potential to contain previously unidentified archaeological resources.

(immediately east of the Dock Cafe at 425 Nelson Street E.). The project's eastern boundary is the St. Croix River (Lake St. Croix). The western boundary is the St. Croix River Crossing Lower Loop Trail (Loop Trail) completed in 2015 by the Minnesota Department of Transportation (Figure 1). The purpose of the St. Croix Riverwalk and Stabilization Project is to stabilize the shoreline while at the same time separating users for pedestrian safety in an area where there is significant pedestrian, cyclist, and vehicular congestion. Riprap fill and vegetation will be installed along the length of the shoreline, and a 10'-wide concrete walkway will be constructed. The walkway will extend for approximately three- quarters of a mile south of Nelson Street E. Existing shoreline trees and vegetation will be removed and replaced with new trees and vegetation. At the northern end of the project area, the existing concrete panel wall south of the floodwall at Nelson Street E. will be extended. Three nearly identical steel H-pile and concrete overlook platforms will be constructed adjacent to the river and accessed from the existing Lower Loop Trail via new walkway. One overlook will attach to the St. Croix Boat and Packet Company gangways. Two other overlooks to the south are located within Bridgeview Park (Figure 2). The project work areas will be accessed by a haul road utilizing the existing bituminous -paved Loop Trail. From May to July 2020, Landscape Research LLC (Landscape Research) and Two Pines Resource Group, LLC (Two Pines) conducted an investigation of historic and cultural resources for the project. This work was conducted for the City of Stillwater and was based on project information supplied by City Planning and Community Development staff (Wittman 2019). The project requires a Clean Water Act Section 404 permit and therefore must comply with Section 106 of the National Historic Preservation Act (NHPA) of 1969, as amended, and the National Environmental Policy Act (NEPA) of 1969. The purpose of this investigation was to provide an assessment of the National Register of Historic Places (NRHP)-listed and determined eligible historic and cultural resources within the project Area of Potential Effect (APE) and to determine the effect of the proposed project construction on the resources. The APE includes properties within the Stillwater Cultural Landscape District, Stillwater Commercial Historic District and the Stillwater South Main Street Archaeological District, as well as other individually NRHP- listed properties. The APE for Architecture and History accounts for any physical, auditory, or visual impacts to historic properties. It includes the shoreline south of the downtown Stillwater area, portions of the Stillwater original plat (designated as contributing to the NRHP-eligible Stillwater Cultural Landscape District), and the vegetated bluffs along the western edge of Main Street/Highway 95. Encompassed within this greater APE is the study area for effects to archaeological resources. An adverse effect is determined when an undertaking may directly or indirectly alter any of the characteristics of an historic property that make it eligible for listing in the NRHP. Changes that diminish the integrity of the property's location, design, setting, materials, workmanship, feeling or association include potential visual impacts within the sight lines of the property. �.

Project Location Assessment of Effects Riverbank Stabilization and Riverwalk Project, Stillwater, Washington County, MN Landscape Research LLC and Two Pines Resource Group LLC / Draft 7/2020 2.0 METHODS 2.1 Objectives The objective of the investigation was to assess potential effects of the proposed project on NRHP-listed or eligible properties within the APE and to determine any potential adverse effects. All work was conducted in accordance with The Secretary of the Interior's Standards and Guidelines for Archeology and Historic Preservation [48 Federal Register 44716-447401 (National Park Service [NPS] 1983). 2.2 Background Research Inventories and studies conducted by the City of Stillwater and for the St. Croix River Crossing Project for properties within the APE were obtained from the Stillwater Community Planning and Development Office and the Minnesota State Historic Preservation Office (MnSHPO). The project is located within the St. Croix National Scenic Riverway (SCNSR), which includes the Namekagon River and the Upper St. Croix. The SCNSR was established as part of the National Wild and Scenic Rivers Act in 1968. The Lower St. Croix National Scenic Riverway was designated in 1972. The project is also located within the St. Croix River Crossing Project (SCRCP) boundary area. A Section 106 Memorandum of Agreement (MOA; 1994), an Amended MOA (2006) and a Memorandum of Understanding (2006) were prepared for the project. Historic and cultural resources studies of the SCRCP boundary area include those for the Stillwater Cultural Landscape District (Long 1994; Henning 1999a,b; Zellie 2011), the Phase I and II Architectural History Survey for the St. Croix River Crossing Project, Stillwater, Washington County, Minnesota (Stark 2004) and the Intensive Literature Search and Phase I/II Archaeological Investigations for the St. Croix River Crossing Project, Washington County, Minnesota (Terrell 2005). The Stillwater Commercial Historic District National Register Nomination recommended the current Commercial Historic District boundary delineation (Roberts 1991). The MnSHPO was also consulted for information on previously inventoried properties and for additional surveys previously conducted within the APE. Additional information about the Stillwater South Main Street Archaeological District (Terrell 2007) was obtained from Two Pines. 2.3 Field Methods 2.3.1 Area of Potential Effect (APE) The determination of the Area of Potential Effect (APE) for Architecture/History considers where the proposed project could have direct and indirect impacts on cultural resources (Figure 2). The initial study area was defined to include the three -quarter -mile -long Riverbank Stabilization project area with additional identification of viewsheds within and across the area within the Stillwater Cultural Landscape District. The setting for the proposed wall construction south of Nelson Street E., the three overlooks, concrete walkway and riprap fill includes the Lake St. Croix shoreline. All properties are located within the (NRHP-eligible) Stillwater Cultural Landscape District. The Stillwater South Main Street Archaeological District (NRHP-eligible) and most of the Stillwater Commercial Historic District (NRHP) are also located within the APE. With its broad setting in the St. Croix River Valley, the Stillwater Cultural Landscape District is especially sensitive to visual changes that can affect the integrity of the district as a whole. Assessment of Effects / Riverbank Stabilization and Riverwalk Project Stillwater, Washington County, MN Landscape Research LLC and Two Pines Resource Group LLC / Draft 7/2020 3 The APE was defined using historic maps and views including Ruger (1879) and Sanborn (1904-1954) maps, topographic maps, and Google Earth coupled with fieldwork to identify riverbank vegetation and shoreline character at the foot of Nelson Street, along the shoreline, and at the three overlook locations. To account for the steep topography and broad viewsheds that frame the project area to the west within the Stillwater Cultural Landscape District, a portion of the first "bench" of the city's Lake St. Croix (St. Croix River) bluff backdrop that generally follows S. 4th Street was defined as the western boundary of the APE. Although vegetation, buildings, and bluff lines reduce the limits of the APE as seen from the shoreline looking to the south, west, and north, the anticipated visual effects could potentially extend to the west as far as S. 4th Street. S. 4th Street is at the center of the neighborhood historically known as South Hill. Certain historic resources are especially prominent from the Lake St. Croix shoreline, notably the dome of the Washington County Courthouse (1870, NRHP, WA-SWC-466) and the steeple and towers of Saint Michael's Catholic Church (1875, WA-SWC-059), but more direct visual effects from the shoreline are associated with the downtown area and its S. 2nd, S. 3rd, and S. 4th Street architectural backdrops. The APE includes the Stillwater Lift Bridge (1931, NRHP), which provides direct views of the northern end of the project area, and Kolliner Park on the east side of the river. The Stillwater Lift Bridge offers views of the Nelson Street E. floodwall, and proposed wall and walkway construction and Overlook #1. From points across Lake St. Croix within Kolliner Park, views encompassing Nelson Street E., and direct views of Overlook #1 and more distant views of Overlooks #2 and #3 are also included. The APE includes the potential direct effects of new concrete wall, concrete and steel overlook and concrete walkway construction, as well as riprap installation along the Lake St. Croix shoreline within the Stillwater Cultural Landscape District. Individual NRHP-eligible properties within the Stillwater Cultural Landscape District will not experience direct effects but the broad district viewshed, especially to S. 4th Street and within certain view corridors, may have indirect visual effects (Figure 2). With noted exceptions across certain view corridors, buildings and vegetation block most direct views to and from the project area. Due to bluff and vegetation character, at the Overlook #1 area at the St. Croix Boat and Packet Company and at Overlooks #2 and #3 the anticipated visual effect area is limited to approximately the first two tiers of properties along the western bluff edge, in addition to properties below the bluff. Encompassed by the APE is the NRHP-eligible Stillwater South Main Street Archaeological District. The evaluation by Two Pines of potential effects to the district and other potential archaeological resources is reported in Section 7. The APE includes approximately 232.4 acres (94.1 hectares). 2.3.2 Data Collection and Inventory Forms Landscape Research and Two Pines staff reviewed inventory forms and studies conducted for the Stillwater Commercial Historic District, Stillwater Cultural Landscape District, Stillwater South Main Street Archaeological District, and other individually -listed or eligible NRHP properties. Tables 1 and 2 (Appendix) include NRHP-listed and NRHP-eligible properties within the APE. Analysis of the APE for Architecture/History considered viewsheds from points on the Stillwater Lift Bridge, from Kolliner Park on the west side of the river, from the riverbank within the project limits, and from various points across the NRHP-eligible Stillwater Cultural Landscape District. There is diminished ability for the unaided eye to identify small-scale elements such as the riprap edge and the overlook structures from across the river and from other distant points. Views of the project area from the riverfront in the vicinity of the Stillwater Lift Bridge and Nelson Street E. diminish quickly due to blocking by buildings on Main and Water Streets, and vegetation and river bluffs to the south. The viewsheds were photographed from points within the APE and further analyzed using GIS and Google Earth.

Extensive studies of the riverfront and adjacent areas began in the 1970s (Terrell 2005:7). Beginning in the 1980s, historic and cultural resource studies within the current project APE were conducted for various agencies, including the Corps of Engineers, the Minnesota Department of Transportation, and the City of Stillwater. 3.2 National Register of Historic Places Evaluations The Historical Reconstruction of the Riverfront: Stillwater, Washington County, Minnesota (Roberts and Fried 1985) for the United States Army Corps of Engineers included study of the archaeological resources located on a portion of the project APE. Archaeological resources identified in the study are discussed in Section 7. The study also identified railroad resources and other buildings and structures for which no further investigation was recommended (Roberts and Fried 1985:177; Terrell 2005:8). The Stillwater Commercial Historic District, which was NRHP-listed in 1992 (Roberts 1991) and the Cultural Resource Investigation: T.H. 36 and Stillwater/Houlton Bridge Project (Long [Henning] 1994; determined eligible 2001) were the foundation of those present historic districts. The Cultural Resource Investigation, St. Croix River Bridge (Henning [Long] 1999a) further examined Stillwater's cultural resources within the context of the cultural landscape of the St. Croix waterway. The report recommended that the Stillwater Cultural Landscape District was eligible for listing in the NRHP. The district includes 248 contributing properties, 187 non-contributing properties, and one historic archaeological site (Henning 1999a:Appendix 5-15). The Cultural Resources Investigation for St. Croix River Bridge of Kolliner Park amended the district to include Kolliner Park, owned by the City of Stillwater, on the east side of the river (Henning 1999b). The Lake St. Croix shoreline along TH 36/95 from the vicinity of St. Louis Street north to the alignment of Locust Street, the Hersey & Bean Sawmill Site (21 WA91) and the Hersey & Bean Planing Mill Site (21 WA92), were also identified as a single contributing property to the NRHP-eligible Stillwater Cultural Landscape District, part of the Stillwater South Main Street Archaeological District (Terrell 2005, 2007). Located along the shoreline just north of the archaeological district is the Moritz Bergstein Shoddy Mill and Warehouse (WA-OHC-001; NRHP), relocated from its original site in Bayport as part of the SCRCP. The Phase I and II Architectural History Survey for the St. Croix River Crossing Project, Stillwater, Washington County, Minnesota (Stark 2004), provided a Phase I and 11 architectural history investigation for the Minnesota portion of the SCRCP. Nine NRHP-listed or determined -eligible properties identified in the study are located within the current project APE. 3.4 Local Studies Between 1995 and 2002 the City of Stillwater also conducted historic resources studies of eight residential areas. The local studies collectively cover a large portion of the Stillwater Cultural Landscape District. Most applicable to the current project include the studies of South Hill (Roberts 1996), the Hersey Staples & Co. Addition Residential Area (Empson 2000) and the West Half of the Churchill, Nelson & Slaughter Addition Residential Area (Empson 2002). The inventoried properties were not evaluated for NRHP significance. Assessment of Effects / Riverbank Stabilization and Riverwak Project Stillwater, Washington County, MN Landscape Research LLC and Two Pines Resource Group LLC / Draft 7/2020 7 This page intentionally left blank Assessment of Effects / Riverbank Stabilization and Riverwak Project Stillwater, Washington County, MN Landscape Research LLC and Two Pines Resource Group LLC / Draft 7/2020 4.0 HISTORIC CONTEXTS AND AREAS OF SIGNIFICANCE Statewide historic contexts and themes developed by the Minnesota SHPO for the interpretation and evaluation of cultural properties that are associated with properties within the project APE include: • St. Croix Triangle Lumbering, 1830s-1900s • Early Agriculture and River Settlement, 1840-1870 • Railroads and Agricultural Development, 1870-1940 • Urban Centers, 1870-1940 Previous studies resulted in detailed historic contexts for properties located within the project APE, including the Stillwater Commercial Historic District, the Stillwater Cultural Landscape District, the Stillwater South Main Street Archaeological District, and the Moritz Bergstein Shoddy Mill and Warehouse (Zellie 2007; 106 Group and SRF Consulting Group 2005). The Stillwater South Main Street Archaeological District historic contexts are reported in Section 7. 4.1 Stillwater Commercial Historic District The Stillwater Commercial Historic District was listed in the NRHP in 1992. The approximately 11-block district is comprised of 57 contributing buildings, two contributing sites, three contributing structures, one contributing object, four non-contributing sites, and fourteen noncontributing buildings. The one-, two-, and three-story brick and stone buildings include examples of Italianate, Queen Anne, Richardsonian, Classical Revival, and early 20th- century commercial styles. In addition, two contributing sites include Lowell Park; three contributing structures include the Wolf tunnel/cave system, the Lowell Park Pavilion and the Lowell Park Levee. A few properties are associated with lumbering, manufacturing, and government but most are associated with retail commerce (Roberts 1991; Stark 2004:26). The district "reflects the economic activities of both manufacturing and lumbering and is a tangible reminder of the foresight of local businessmen who built a diversified economic base, allowing the city to continue to thrive after the white pine industry collapsed in the early years of the twentieth century" (Roberts 1991). The district is significant under Criteria A and C in the areas of architecture and commerce. Historic contexts for the district are "The Development of Stillwater, 1860-1940," and "St. Croix Triangle Lumbering, 1830s-1900s." The period of significance is 1860 to 1940. The district retains a good level of historic integrity and remains eligible for listing in the NRHP. 4.2 Stillwater Cultural Landscape District The Stillwater Cultural Landscape District was determined eligible for the NRHP in 2001. The boundaries of the district reflect the City's original plat and the steep topography and vegetated bluffs that comprise the bowl -like setting (Henning 1999a:42). The district is significant under Criterion A, for development directly associated with events that have made a significant contribution to the pattern of development along the St. Croix River, such as lumbering and logging, and under Criterion C, as an embodiment of the distinctive characteristics and appearance of the periods of development. The areas and periods of significance are Planning and Community Development, 1839-1939; Industry (Lumber), 1860s-1914; Social History, 1839-1940 and Architecture, 1848- 1927. The district contains 248 contributing properties and 187 non-contributing properties, including nine properties within the project APE that are individually listed in the NRHP or determined eligible, including the NRHP-listed Stillwater Commercial Historic District (Henning 1999a:Appendix 5-15). Assessment of Effects / Riverbank Stabilization and Riverwak Project Stillwater, Washington County, MN Landscape Research LLC and Two Pines Resource Group LLC / Draft 7/2020 9 As documented by Henning (1999a), important landmarks with high visibility in the river setting and within the project viewshed include the Washington County Courthouse (NRHP; WA-SWC-466), the Mortimer Webster House (NRHP; WA-SWC-007), and St. Michael's Catholic Church (WA-SWC-059). All are located within the South Hill residential neighborhood. In the downtown riverfront area, the Commodore Elevator (not previously inventoried), the Stillwater Lift Bridge (NRHP; WA-SWC-322) and Lowell Park (WA-SWC-325) were also noted as important visual features (Henning 1999a:42-48; Stark 2004:41). 4.3 Stillwater South Main Street Archaeological District The Stillwater South Main Archaeological District was determined eligible for the NRHP in 2010. The boundaries of the district encompass three contributing archaeological sites: the Hersey & Bean Sawmill (21WA91), the Hersey & Bean Planing Mill (21WA92), and Slab Alley (21WA100). The district is significant under NRHP Criterion A for its association with events, such as lumbering and neighborhood development, that shaped the community of Stillwater, and under Criterion D for its ability to yield information that is important to our understanding of the technology of the lumber industry and community development in Stillwater (Terrell 2005:54; Terrell 2007). The district is significant in the areas of Industry and Social History during a period that commences in 1854 with the construction of the main Hersey & Bean Lumber Company sawmill and continues through the 1932 removal of the remaining homes of the Slab Alley neighborhood (Terrell 2007). 4.4 Moritz Bergstein Shoddy Mill and Warehouse The Moritz Bergstein Shoddy Mill and Warehouse (1890) were listed in the NRHP in 2008 and moved to 805 S. Main Street in 2015 (Zellie 2007; 106 Group and SRF Consulting Group 2005; Lauber and Claybaugh 2015). They are eligible for listing under Criterion A in the areas of Social History and Industry (c.1890-1910). Assessment of Effects / Riverbank Stabilization and Riverwak Project Stillwater, Washington County, MN Landscape Research LLC and Two Pines Resource Group LLC / Draft 7/2020 10 4.5 Historical Overview Through treaties signed in 1837, the Dakota and Ojibwe ceded the land comprising the St. Croix delta to the United States. This land triangle extended from the confluence of the St. Croix and Mississippi rivers, north to a line from the mouth of the Crow Wing River and then east to the St. Croix River. The forest resources of this property, in what was then Wisconsin Territory, were especially well understood by New England timber prospectors; the delta was regarded as the "richest white pine land on the continent" (Waters 1977:144; Roberts and Fried 1985:30). White settlement in the Stillwater vicinity began in 1839 when trader Joseph R. Brown platted the town of Dakotah at the north end of the present-day city (Folsom 1888:52). This area would remain part of Wisconsin Territory until 1849, when the Minnesota Territory was formally organized, and St. Paul was named its capital. In 1843 Jacob Fisher staked a claim that included the Stillwater riverfront, and industrial development and permanent white settlement began after John McKusick and his associates purchased the property. The investors constructed a water -powered sawmill on a narrow plateau facing Lake St. Croix between Myrtle and Mulberry streets. Water supplied by Lake McKusick atop the bluff was conveyed along a canal cut from Brown's Creek to the lake. It was then channeled to a ravine and a wood flume built along Mulberry Street and above the rooftops of the village and fell about 150 feet to the two-story mill (Dunn 1965:100; Warner and Foote 1881:513; Roberts and Fried 1985:32). This was the first of a generation of mills that would line the riverfront levee. By the time Washington County lands opened to public sale in the 1840s, the McKusick mill had already supplied lumber to markets in St. Paul and St. Anthony (Warner and Foote 1881:502). Although flood - prone, the riverfront site provided a good harbor for steamboats bringing passengers, freight, and mail. The early levee was between Myrtle and Chestnut streets. After 1875, a stone wall was built to reinforce the section between Chestnut and Nelson streets (Vogel 1993:37). At the time of permanent white settlement in the 1840s and 1850s, about one -fifth of the present-day city was covered with a hardwood forest that included oak, maple, basswood, and hickory. Prairie and oak openings as well as lowland meadows comprised much of the rest of the surface, along with marshland. Woodland tracts were cleared for agriculture, and there was little undisturbed grassland by 1900. Single specimens of deciduous trees such as oaks are all that likely remain from this landscape (Vogel 1993:28). In 1848, McKusick platted a 46-block grid -plan townsite; in 1857, an observer commented that Stillwater's bluffs "retreated from the lake in the form of a semi -circle," and reported that the townsite was placed only a few feet above high water mark, and compared the city's steep grades ascending from the river to those in Quincy, Illinois or Natchez, Mississippi (Bond 1857:158). Another observer noted that with its bowl -like enclosure and high bluffs slashed with ravines, Stillwater was not a choice site for a town, but a "perfect situation for sawmills" (Glaser 1943:203). The steep hills and ravines prohibited construction of some of the streets drawn on the original townsite plat. As in many other Minnesota river towns, the townsite surveyor oriented the plan to the river, while most subsequent additions were oriented to the cardinal points of the compass (Figure 3). The McKusick mill founded in 1843 marked the beginning of Stillwater's first period of lumber manufacture, one that extended until the arrival of the railroad in 1871. Early businesses depended entirely on river transportation between November and late spring and were subject to delays during periods of flood and drought. Early mills were initially powered by direct waterpower, which was replaced by steam technology in the 1850s. Assessment of Effects / Riverbank Stabilization and Riverwak Project Stillwater, Washington County, MN Landscape Research LLC and Two Pines Resource Group LLC / Draft 7/2020 11 With the opening of public land sales, farmers were drawn to outlying Washington County, but the county population in 1850 of 1,056 found 620 of the total in Stillwater, evidence of the importance of lumbering to the early economy. In 1851, Stillwater was selected as the site of the State Prison and the facility was placed in Battle Hollow (on N. Broadway between E. Laurel and Elm streets) at the edge of the sawmill district. In 1854 Stillwater organized as a city and elected John McKusick, its first sawmill owner, as mayor. The city's position in the St. Croix lumber industry soared when the St. Croix Boom Company. incorporated in 1851, established a new boom site about two miles north of Stillwater in 1856 (Terrell 2015a:31-32). At this location, logs were collected, measured, and rafted downriver, creating a distribution point for the entire St. Croix. From the boom site, rafts containing millions of board feet of lumber were directed to the city's mills and were also bound for Winona, St. Louis, and other mill sites. The hundreds of men employed during the open -water season directly benefited the city's early economy (Waters 1977:145). The price of land rose and then fell sharply, with Stillwater's first cycle of growth following the speculative pattern of many Minnesota river cities just before the national Panic of 1857 and the Civil War. Inexpensive frame buildings made up much of the early commercial district. By the end of the Civil War in 1864, however, the owners of the six sawmills then in operation began to build enduring integrated business networks that also included real estate, flour milling, banking and insurance, manufacturing, and transportation. Lumbering financed new enterprises, and new buildings reflected increased investment (Henning 1999a:25). Many early sawmill firms would remain in business until the end of the lumber era. For example, the mill of the Hersey, Staples & Co., established in 1853, remained in business until 1906. This property, at the south end of the city, is now part of the NRHP-eligible Stillwater South Main Street Archaeological District. Rough surface roads and seasonal steamboats were Stillwater's only conduits for trade prior to 1871. In 1867, area business leaders organized the Stillwater & St. Paul Railroad. The two railroads that followed immediately brought economic and population growth and secured the city's position as a lumber center. In 1871 the Stillwater, White Bear and St. Paul Railroad connected Stillwater with Minneapolis, St. Paul, and Duluth. In 1872, the St. Paul, Stillwater, and Taylor's Falls Railroad reached the city. By 1878 the Stillwater and St. Paul became part of the Northern Pacific transcontinental system. Two other lines followed, and rails and spurs were laid across the riverfront to sawmills and factories. They also connected to a depot supplying freight and passenger service as well as river steamers. In 1876 a pontoon supported, wood drawbridge spanned the river to Houlton, Wisconsin. This structure was rebuilt in 1911 and occupied the site of the present Stillwater Lift Bridge (1931; NRHP; Figure 7). In 1870, with about 4,000 inhabitants, Stillwater was the largest settlement in Washington County. From its "commanding position" at the head of Lake St. Croix, one observer described it as "the commercial and manufacturing center of the entire St. Croix lumbering district" (Henning 1999a:25). The 1870 bird's eye view of Stillwater shows the townsite creased with lightly wooded ravines, and the beginning of significant residential development is evident: between 1870 and 1871, more than 200 houses were erected. By 1879, and the publication of the next bird's eye view, the ravines are edged by residential development, and the commercial district is a dense backdrop for the riverfront mills, rail yards, and landings (Ruger 1870, 1879; Figure 3). By 1900, eleven sawmills would locate on the levee (Roberts and Fried 1985:32-39; Figures 4-6).

Albert Ruger, lithographer; reproduction from Empson Archives. Rail connections allowed local manufacturers to produce lumber, lath, shingles, doors, sashes and furniture, instead of continuing to raft sawn lumber downriver to other markets for processing. A population surge reflected the success of the lumber companies and new manufacturing: Stillwater grew to 9,055 in 1880; 11,260 in 1890; 12,318 in 1900 and 12,435 in 1905. The peak year for lumber traffic on the St. Croix was 1890, when one half -billion board feet passed through the St. Croix Boom (Waters 1977:146). The boom closed in 1914, marking the end of Stillwater's lumber era. The closing of the St. Croix Boom Company in 1914 was a critical event in the city's economic history. Riverfront mill and factory buildings were put to other uses, but the new businesses were often short- lived. Investment in diversified manufacturing, including agricultural implements, allowed the city to retain its workforce and position as a trade center. The city's population stood at 10,978 in 1910, but declined to 7,735 in 1920 and 7,013 in 1940. Northwest Thresher, Twin City Forge and Foundry, the Connolly and Foote -Schultze shoe companies, Smithson Paper Box Company, Stillwater Market Creamery, Minnesota Mercantile Company, and Stillwater Garment Company were among the city's important early twentieth-century employers on or near the riverfront. During the next decades, the riverfront area was slowly transformed by removal of railroad tracks, industrial buildings, and boathouses.

Stillwater riverfront south of Locust Street, November 1898. (Sanborn Map Company) Assessment of Effects / Riverbank Stabilization and Riverwalk Project Stillwater, Washington County, MN Landscape Research LLC and Two Pines Resource Group LLC / Draft 7/2020 16 Although the riverfront would continue to be used by industry for several more decades, the initial construction of Lowell Park (1911) represented the first step in reworking the city's gateway and accommodating new automobile traffic. Initially designed by William A. Finklenburg of Winona, the park extended two blocks south of Chestnut Street and featured a river wall with a lawn, plantings, and concrete benches. A north extension was completed in 1917 with plans by Minneapolis landscape architects Morell & Nichols, and a riverfront pavilion was completed in 1923. The firm also prepared the Plan of Stillwater (1918). It was a blueprint for the modern city, proposing new ideas for parks, boulevards, housing, and riverfront land use. It called for a system of scenic drives linking views of the river valley, and the reclamation of ravines for park purposes (Morell and Nichols 1918:15-21). The landscape architects also revisited and promoted the once -popular idea of making the St. Croix River navigable between Lake Superior and the Mississippi River, and envisioned an industrial riverfront coexisting with recreational use. The river's role in industrial transportation continued to decline, however. In 1921, the U.S. Army Corps of Engineers reported that the St. Croix was "principally used by excursion steamboats and pleasure launches." The number of river passengers declined steadily: in 1917, 11,337 were carried; in 1921, only 1,092 (United States Army 1922:826). In 1917 the East Side Lumber Company on the Wisconsin side of Lake St. Croix donated their property to the City of Stillwater for park use. In 1923, the land was developed as a Tourist Camp and in 1931 American Legion Post 48 constructed Legion Beach. The site was later named Kolliner Park. It has been closed since 1979 (Minnesota Department of Transportation). When the new Stillwater Lift Bridge opened in 1931 it became the centerpiece of a redesigned riverfront. The two-lane, 1,050-foot bridge was completed just as the city was facing the Great Depression, but also at a time when city leaders planned to build on future tourism and recreation markets.

South half of Lowell Park and levee in 1922, looking north. (Runk 720 MNHS) Beginning in the 1980s, many Stillwater buildings underwent historic rehabilitation and adaptive reuse, including those in the Stillwater Commercial Historic District. Within the proposed project area APE, former riverfront industrial and railroad areas were redeveloped with the new Dock Cafe and the St. Croix Boat and Packet Company marina, as well as paved surface lots extending to S. Main Street near the cafe and marina (Figure 13). The proposed project area APE also includes the paved Loop Trail (2015), which occupies a portion of the former railroad right-of-way, and the Moritz Bergstein Warehouse and Shoddy Mill at 801 S. Main Street (1890, NRHP), relocated in 2015 from Bayport (Figures 30, 32). The Loop Trail and the Moritz Bergstein Warehouse and Shoddy Mill relocation projects were part of the St. Croix River Crossing Project (SCRCP), which included the construction of the St. Croix Crossing Bridge (2017). Photographs and aerial views of the proposed project area from c. 1922 to the present document building clearance as well as evidence of filling and the gradual growth of vegetation, including deciduous trees rooted along the sandy and rocky shoreline (Figures 9-11, 29, 34).

The project includes activities that could have potential adverse effects on historic and cultural resources and the broad Stillwater Cultural Landscape District. They include riverfront tree and vegetation removal, concrete panel wall construction, riprap fill installation, concrete overlook construction, and concrete walkway construction. The bituminous -paved St. Croix Crossing Bike/Pedestrian Loop Trail (Loop Trail), extends between the St. Croix Crossing Bridge and Stillwater Lift Bridge within the project area, and edges the length of the project area (Figure 32). 5.1.1 Riverbank between Nelson Street E. and St. Croix Boat and Packet Company Marina A concrete panel wall and 10' concrete walkway will be constructed along the riverfront in front of the Dock Cafe, east of the Army Corps of Engineers levee wall at Nelson Street E. (Figure 15). Existing trees in the City's easement areas will be removed (Figures 12-13; 16-18). A steel I-beam and precast concrete panel wall, painted to match the existing wall, and riprap fill will be installed along the existing shoreline. No pipe rail fence will be installed and the walkway surface will be at water level. The City will utilize an alternative design that incorporates the Sam Bloomer/Nelson Street right-of-way intersection to connect an existing accessible ramp to the trail without existing levee wall removal. The concrete panel wall will follow the riverfront to the south end of the Dock Cafe. From this point to the Moritz Bergstein Shoddy Mill and Warehouse site (NRHP), the river's edge will be filled with riprap and the 10' concrete walkway will continue alongside the existing bituminous -paved Loop Trail. New flood -tolerant vegetation at the shoreline will include native grass and wet seed mix.

(City of Stillwater/AMI 2019) 5.1.2 Riprap Fill and Vegetation South of Nelson Street and the Dock Cafe and elsewhere along the shoreline, existing trees will be removed and the shoreline will be filled with riprap (Figure 18). Riparian and prairie seed mix will be planted as a groundcover for ferns, chokecherry, false indigo, dogwood, and willow spaced 4' to 6' apart in riprap fill. A total of 170 shrubs will be planted. To replace trees removed to the south of the St. Croix Boat and Packet Company marina, a total of 36 Black Spruce and Mountain Maple will be spaced at a minimum of 10' intervals. 5.1.3 Walkway Design A 10' concrete walkway between the south end of the Dock Cafe and the Moritz Bergstein Warehouse and Shoddy Mill will be installed at and slightly above grade. The walkway will continue along the project area on the east side of the riprap fill adjacent to the paved Loop Trail. 5.1.4 Overlook Design Nearly identical overlooks will be installed at the St. Croix Boat and Packet Company loading dock, and at two locations in Bridgewater Park (Figures 19, 22, 25, 28). Each steel H-pile and concrete structure is 20' square and contains 400 square feet. The concrete exterior surface will be stained brown to blend with the surrounding environment. Black pipe -rail fencing, of a design previously approved by the Minnesota Department of Transportation (MnDOT) and other agencies, will be installed along the perimeter of the overlooks.

Indirect effects include visual effects, including addition of new visual elements within the boundaries of the Stillwater Cultural Landscape District or within viewsheds across the Stillwater Historic District. As noted in Sections 4.5 and 7.2, historic maps and photographs and previous studies document land use change along the length of the Stillwater riverfront including the project area APE (Roberts and Fried 1985; Stark 2004; Terrell 2005). The shoreline has had extensive modification due to cycles of filling and grading for industrial development, including those for railroad, lumber, and mill and manufacturing land uses, as well as 20th-and 21st-century recreational use. Historic photographs dating from c. 1880 to 1965 show the changing conditions, including those of the shoreline and levee. With few recent exceptions such as those around the Dock Cafe, existing tree and vegetation cover does not appear to be part of a plan associated with public park or private development. The period of significance for the Stillwater Cultural Landscape District in the area of Planning and Community Development is 1839-1939 (district determined NRHP-eligible). Lowell Park, immediately to the north of Nelson St. E., is a contributing property in the Stillwater Commercial Historic District (NRHP). 6.1 Nelson Street E. and Dock Cafe Wall The section of levee wall proposed for alteration at Nelson Street E. was rehabilitated in 1996. The area along the levee was filled prior to 1924 (Roberts and Fried 1985). The Dock Cafe and the surrounding deck and riverfront landscaping were completed in c. 1987. The proposed wall will alter the present shoreline character by introducing new features where previously vegetation and more "natural" shoreline character prevailed, but much of the existing landscape appears to date from the 1970s to the present (Sanborn 1924; Roberts and Fried 1985; MHAPO ). As viewed from the Stillwater Lift Bridge (NRHP), the overall visual impact of proposed changes to the riverfront end of Nelson Street E. will be minimal. This also includes the adjacent view of the adjacent Lowell Park (contributing to the Stillwater Cultural Landscape District and Stillwater Commercial Historic District). Views of this area from the Lift Bridge will not be significantly altered, nor those to the west along Nelson Street E., at the southern edge of the Stillwater Commercial Historic District (Figures 12-17). The view corridor from the foot of Nelson St. E. extends to the east above 2nd Street S. and to the bluff edge along 4th Street S. Looking west from the top of 2nd Street S. to the street terminus at the levee, proposed wall construction at Nelson Street E. will also result in a minimal impact on the view of the Stillwater Cultural Landscape District. Based on this assessment, the Nelson Street E. and Dock Cafe Wall is located in an area of introduced fill, adjacent to a wall rehabilitated in 1996, and new construction will not impact the architectural and historic resources related to the Stillwater Commercial Historic District and Stillwater Cultural Landscape District. The qualities of setting, feeling, and association associated with the Stillwater Cultural Landscape District shoreline will not be impacted. 6.2 Riprap Fill and Vegetation The shoreline extending south from Nelson Street E. has mixed conditions resulting from past construction and filling. For example, most recently, in 2012, to prepare for moving the Moritz Bergstein Warehouse and Shoddy Mill (NRHP) to its current site at 801 S. Main Street, a vacant barge terminal Assessment of Effects / Riverbank Stabilization and Riverwak Project Stillwater, Washington County, MN Landscape Research LLC and Two Pines Resource Group LLC / Draft 7/2020 33 building was demolished, the site elevation was raised to a one foot above the 100-year floodplain, and the shoreline was stabilized (Lauber et al. 2015:14). However, the heavily vegetated, sandy and rocky shoreline appears to most viewers as a natural feature within the Stillwater Cultural Landscape District and despite past industrial use retains general qualities of setting, feeling and association (Figure 29). The proposed riprap will introduce a uniform edge along a shoreline that has had other past alterations during and after industrial and railroad use. Shoreline stabilization may consist of either soil filled riprap and/or vegetated erosion control mats. There will be initial loss of all vegetation, which will be mitigated by a tree and vegetation replanting plan. Overall, and especially as the area is revegetated, the riprap installation will result in a minimal overall visual effect on the shoreline edge of the Stillwater Cultural Landscape District. Based on this assessment, the new construction will not impact the architectural and historic resources of the Stillwater Cultural Landscape District, and the qualities of setting, feeling and association. Figure 29. Shoreline character near Overlook #2, looking southeast, 7/8/2020. (Daniel Pratt). 6.3 Overlooks and Walkway As noted in Section 4.5 and 7.2, the shoreline was in extensive industrial use during the Stillwater Cultural Landscape District's period of significance under Criterion A for Industry (c.1860s-1914). The shoreline retains good levels of the qualities of setting, feeling and association despite decades of disturbance from industrial and railroad construction. The three proposed concrete -and -steel overlooks are new non -historic structures within the Stillwater Cultural Landscape District (Figures 2, 19). Each overlook can be observed from across several viewsheds, depending on surrounding topography and viewpoints such as the Stillwater Lift Bridge (1948, NRHP). As shown in Figures 13-14 and Figure 20, from the river to the west and the Loop Trail to Assessment of Effects / Riverbank Stabilization and Riverwalk Project Stillwater, Washington County, MN Landscape Research LLC and Two Pines Resource Group LLC / Draft 7/2020 34 the east, the view of Overlook #1 is blocked by boats at most times, but is seasonally visible from the bluff on Broadway Avenue to the west, from a point adjacent to the Mortimer Webster House (1865-66, NRHP). The overlook construction is part of modern marina development of gangways and other facilities. The simple design of the overlook appears to be compatible with its setting adjacent to the Loop Trail. Although constituting new feature in the Stillwater Cultural Landscape District, its presence will not impact on the District's qualities of location, setting, feeling, or association. As proposed, Overlooks #2 and #3 will not be highly visible from the Stillwater Lift Bridge (Figures 23, 26) and would constitute small elements, depending on season, as seen from across the river at Kolliner Park. Overlook #2 will be located to the south of the Moritz Bergstein Warehouse and Shoddy Mill (NRHP). The warehouse and mill were moved to the current location in 2015 and although the property remains listed in the NRHP it does not retain integrity of location and setting and has diminished qualities of feeling and association. Overlook #2 and riprap installation will have minimal effect on the property. Figure 30. Moritz Bergstein Warehouse and Shoddy Mill on Loop Trail, looking north, 7/8/2020. (Daniel Pratt) Overlook #2 is proposed for construction to the south of an existing stormwater outlet, and Overlook #3 to the north of an existing stormwater outlet. The overlooks will occupy heavily vegetated but non - historic shoreline disturbed by introduced fill and past industrial use, as noted in Sections 7.4.2.2 and 7.4.2.3. The simple proposed design of the small overlooks in this setting appears to be compatible with the surrounding shoreline and landforms. Although constituting new features in the Stillwater Cultural Landscape District, their presence will not impact the District's qualities of location, setting, feeling, or association. Assessment of Effects / Riverbank Stabilization and Riverwalk Project Stillwater, Washington County, MN Landscape Research LLC and Two Pines Resource Group LLC / Draft 7/2020 35 Portions of the proposed concrete walkway will occupy the former St. Paul, Stillwater & Taylors Falls Railroad (StPS&TF) corridor (WA-SWC- 150 1). Construction will require a moderate amount of grading and filling. The StPS&TF alignment been previously evaluated and determined to be ineligible for listing on the NRHP (Stark 2004:102-4). Some of this roadbed is already occupied by the bituminous -paved Loop Trail. When viewed from the trail, the proposed walkway will have minimal visual effect in an area already disturbed by railroad track removal and introduced fill. Although constituting a new feature in the Stillwater Cultural Landscape District, the walkway will not impact the District's shoreline qualities of location, setting, feeling, or association. 6.4 Summary and Conclusions Based on review of historical documents, previous studies, proposed project plans, and fieldwork, the project as proposed will not have an adverse effect on architectural and historical resources within the Stillwater Cultural Landscape District and Stillwater Commercial Historic District. Direct effects from new construction are limited to the Lake St. Croix shoreline where they will occur in areas of introduced fill. Indirect visual effects from key sightlines, including those from the Stillwater Lift Bridge (NRHP) and the Washington County Courthouse (NRHP), do not impact the Districts' qualities of location, setting, feeling, or association. Assessment of Effects / Riverbank Stabilization and Riverwak Project Stillwater, Washington County, MN Landscape Research LLC and Two Pines Resource Group LLC / Draft 7/2020 36 7.0 ASSESSMENT OF EFFECTS TO ARCHAEOLOGICAL RESOURCES The study area for the assessment of effects to archaeological resources is limited to the that portion of the APE encompassed by the project's construction limits and the boundary of the NRHP-eligible South Main Street Archaeological District (Figure 31). Planned activities within the construction limits include riverfront tree and vegetation removal, concrete panel wall construction, rip rap installation, concrete overlook construction, and concrete walkway construction.

(Two Pines / AMI 08.30.2019) Assessment of Effects / Riverbank Stabilization and Riverwalk Project Stillwater, Washington County, MN Landscape Research LLC and Two Pines Resource Group LLC / Draft 7/2020 37 7.1 Previous Archaeological Studies As early as 1971, archaeological studies were undertaken in anticipation of the construction of an alternative St. Croix River crossing near Stillwater. Among the routes explored was a broad south corridor aligned with TH 36. In 1971, the Minnesota Trunk Highway Archaeological Reconnaissance Survey (MTHARS) began investigations along this corridor and additional work was carried out by MTHARS staff in 1987 and 1989 (Nystuen 1972:54; Peterson et al. 1988:232; Peterson et al. 1990:244). After the completion of a draft environmental impact statement (EIS) in 1990 led to the selection of the southern corridor as the preferred alternative, Loucks & Associates, Inc. conducted further cultural resource investigations in 1994 for the southern corridor and crossing (Long 1994a; Peterson et al. 1994:400). Nine archaeological sites were identified during these investigations, but none were recommended as NRHP eligible (Terrell 2005:7-8). In 1999, Rivercrest Associates, Inc. conducted cultural resource investigations to assess the effect of removing the existing NRHP-listed Stillwater Lift Bridge (Henning 1999). During this study, two archaeological sites, 21WA91 (Hersey & Bean Sawmill Site) and 21WA92 (Hersey & Bean Planing Mill Site), were documented. Together, these two sites were identified as a single contributing property to the NRHP-eligible Stillwater Cultural Landscape District. In 2004, in support of the preparation of a Supplemental Draft EIS, Two Pines completed a literature search and Phase I and II archaeological investigations for four crossing alternatives. During this work, the previously identified archaeological sites 21 WA91 (Hersey & Bean Sawmill Site) and 21 WA92 (Hersey & Bean Planing Mill Site) were evaluated, and one new archaeological site, 21WA100 (Slab Alley) was identified and evaluated. While each of the sites was recommended as individually eligible for inclusion in the NRHP, it was further recommended that they be grouped within a contiguous archaeological district (Stillwater South Main Street Archaeological District). Together the sites "provide insights not only into the technology of turning logs into lumber, and the nature of working-class life in nineteenth-century Stillwater, but also the direct correlation between logging and lumbering and the development of the Stillwater community" (Terrell 2005:ii). In conjunction with the SCRCP, a nomination form was prepared for the Stillwater South Main Street Archaeological District in 2007 and the district was officially determined eligible for listing on February 2, 2010 (a private landowner objected to listing). A part of the SCRCP was the construction of the St. Croix Crossing Bike/Pedestrian Loop Trail (Loop Trail), which is a 4.7-mile bicycle and pedestrian route utilizing the St. Croix Crossing Bridge and the historic Stillwater Lift Bridge. Because the Loop Trail passes through the Stillwater South Main Street Archaeological District, among the mitigation measures outlined in the 2006 amendment to the 1994 Section 106 Memorandum of Agreement (MOA) for the SCRCP was the avoidance and minimization of effects to the District during the design and construction of the Loop Trail (Figure 32). Dr. Michelle Terrell from Two Pines provided consultation as Loop Trail project plans progressed; attended monthly project planning meetings; and prepared an Archaeological Resources Protection Plan for the District (Terrell 2015b). During construction of Phase 1 (2015) and Phase 2 (2018) of the Loop Trail, Two Pines staff monitored subsurface investigations within the district boundary. During construction of Phase 1 (Lower Loop Trail), no significant archaeological features or deposits were encountered (Terrell 2016). During monitoring of Phase 2, unanticipated archaeological features related to the Hersey & Bean Sawmill (21WA91) were encountered during excavation for stormwater pipe and structures (Terrell 2019). The MnDOT Cultural Resources Unit and State Historic Preservation Office concurred that the loss of all, or part, of the identified features would constitute an adverse effect to the historic property. Because the features could not be avoided, per Stipulation IV.F.2 of the amended Section 106 MOA for the SCRCP, the elements that would undergo an adverse effect from the project were documented in accordance with a developed mitigation plan (Terrell 2018). Those investigations were completed in 2018 (Terrell 2019).

(Two Pines) 7.2 Historic Context: Hersey & Bean Lumber Company The third sawmill to be constructed at Stillwater was built by the mill company of Hersey, Staples and Company, which was formed in 1853 by Samuel F. Hersey and Isaac Staples and two additional stakeholders (Warner and Foote 1881:515; Larson 1949:19). The company was an East Coast enterprise, and Hersey, who resided in Maine, relied on Staples, and later Charles and Jacob Bean, to oversee operations in Minnesota (Larson 1949:21). The mill itself was known as the company's North Western Mill (Warner and Foote 1881:515). The company that operated this mill would go through several partnership evolutions including Hersey, Staples & Hall; Hersey, Staples, & Bean; Hersey, Bean & Company; and Hersey, Bean & Brown; before becoming the Hersey & Bean Lumber Company in 1875 (Warner and Foote 1881:515; Larson 1949:21). In 1891, George H. Atwood would take over the mill's ownership, but the company continued to be known as Hersey & Bean until the mill closed and was sold to a salvager in 1906 (Railway Publishing Company 1903:16; Empson 2000:58). Assessment of Effects / Riverbank Stabilization and Riverwalk Project Stillwater, Washington County, MN Landscape Research LLC and Two Pines Resource Group LLC / Draft 7/2020 39 Throughout its history the North Western Mill of the Hersey & Bean Lumber Company was noted for its advanced technology (Larson 1949:19). From its initial construction in 1854 as a steam -powered enterprise, the mill was an improvement over the previous water -powered mills constructed along the St. Croix River. Other improvements included the use of a gang saw, with its bands of parallel sash saws, and the presence of a circular, or rip, saw that was the first of its kind employed at Stillwater (Larson 1949:20). So efficient was the mill that it was said, "Everything about the mill is done by machinery, even to the filing of the saws, the handling and shifting of the lumber, and the removal of slabs" (Larson 1949:20). When the mill went into production in July of 1855 its initial capacity was approximately 40,000 ft. of lumber per day or 12,000,000 ft. per year in addition to 2,500,000 ft. of lath (St. Croix Union, February 13, 1855; Warner and Foote 1881:515; Kane 1952:205). During the winter of 1872 to 1873 the mill was largely remodeled and rebuilt, and new machinery was installed (Warner and Foote 1881:515). In 1881, the updated mill was described as being a 66 ft. x 150 ft. frame building containing a gang saw of 46 parallel sash blades; one double rotary saw; and one muley saw, which together produced 90,000 ft. of lumber per day. The mill also contained two shingle machines that produced 100,000 shingles per day, and a lath machine that produced 50,000 ft. per day (Warner and Foote 1881:515). This machinery was powered by two engines that were fed by a series of boilers (Warner and Foote 1881:515). The flue for this mill ran underground to a smoke stack located atop the bluff to the west of the mill. Other features associated with the mill included a store/office, a refuse burner, drying kilns, warehouses, a blacksmith shop, and railroad sidings. The presence of rail yards at the Hersey & Bean sawmill reflect the change in lumber shipment that was brought about by the introduction of the railroad to Stillwater in 1871. Prior to 1872, all of the lumber was sent down the river, or used locally, but with the introduction of the railroad nearly all the Hersey & Bean lumber was shipped by rail (Warner and Foote 1881:516). The remodeling of the North Western Mill that took place in 1872 and 1873 was an adaptation to the introduction of this rail line. One of the company's other adaptations to the rise of the railroad was the construction in 1873 of a specialized planing mill (Warner and Foote 1881:515). This separate mill, referred to as the "Little Mill" was constructed to the south of the main mill and was designed to cut the long pieces of lumber that were necessary for the construction of railroad bridges (Warner and Foote 1881:515; Sanborn Map Company 1884). Like the main sawmill, the flue for this mill extended underground to the west to a smokestack located on the bluff. The planing mill was partially damaged by fire in 1887 and rebuilt on the same location by 1888. The rebuilt planning mill was described as "without doubt the most perfect and complete mill of its kind in America, and which, like their saw mill, contains the latest and most approved machinery" (Barrett 1887). As the twentieth century dawned, the logging boom began to fade. The once apparently limitless supply of timber was reaching its end and soon the industry would transfer its interests west to new pineries that were now accessible by rail. By 1904, George Atwood, who was operating the North Western Mill as the Atwood "A" Mill, was faced with log shortages that forced him to temporarily shut down the mill (Stillwater Gazette, April 9, 1904 and June 10, 1904). Although an optimistic Atwood reported in November of 1904 that all three of his mills would be operational during the following season, in the spring of 1905 the mill did not reopen (Stillwater Gazette, November 12, 1904; Stillwater Daily Gazette, April 3, 1905). By June of the following year it was reported in the Stillwater Messenger (June 9, 1906) under the heading "A Land Mark Disappears" that: The old Hersey & Bean sawmill — that old land mark in the southern part of the city that has attracted the attention of everybody entering Stillwater from that section for so long — has been sold to a Saginaw mill wrecking concern and will be dismantled and the machinery shipped away. Assessment of Effects / Riverbank Stabilization and Riverwak Project Stillwater, Washington County, MN Landscape Research LLC and Two Pines Resource Group LLC / Draft 7/2020 40 That same year both the Hersey & Bean Lumber Company's former North Western Mill and the Little Mill were dismantled and removed (Stillwater Gazette, June 6, 1906; Sanborn Map Company 1910). When the last log drive on the St. Croix River occurred in 1914, only the former store/office building remained to mark the location of one of Stillwater's largest sawmill enterprises (Dunn 1965:113). During the first half of the twentieth century, the site was used as the Stillwater Municipal Barge Terminal, and later it was the site of the Terra Terminal fertilizer warehouse (constructed just north of the district boundary). Throughout their history, the Hersey & Bean Lumber Company's mills exhibited the latest technologies for turning logs into lumber and illustrated the New England approach to logging in the St. Croix Valley. From the construction of a steam -powered mill, to the use of the first circular saw at Stillwater, and the adaptation to the introduction of the railroad, the Hersey & Bean Lumber Company embraced new technologies that improved the efficiency of lumber milling. 7.3 Archaeological Sites Construction activities related to the St. Croix Riverwalk and Stabilization Project will occur only within that portion of the Stillwater South Main Street Archaeological District located to the east of TH 95 which includes sites 21 WA91 (Hersey & Bean Sawmill) and 21 WA92 (Hersey & Bean Planing Mill). The locations of Overlook #2 and Overlook #3 are located within the boundary of site 21 WA91. 7.3.1 Site 21WA91 (Hersey & Bean Sawmill) Site 21 WA91 consists of the archaeological remains of the Hersey & Bean Lumber Company's North Western mill complex. Sited on the southern edge of town, the main sawmill complex was erected on a half mile -long, level section of riverfront bound to the west by a steep wooded bluff and to the east by the bank of the St. Croix River. This location on the river flats provided ready access to logs floated down the river from a tributary network of streams in the pine forests of northern Minnesota and Wisconsin, while at the same time being convenient to the road leading south from downtown Stillwater, as well as to the railway when it was constructed — both of which ran to the immediate west of the mill along an intermediate river terrace. Located adjacent to these avenues of transportation (river, road, and railway), the mill complex was ideally situated for the collection and milling of logs and the transportation of lumber. In 1903, fifty years after its inception, the Hersey & Bean sawmill was still described as "the largest and most modern of any to be found in the St. Croix River valley" having "every modern appliance and equipment for manufacturing and handling lumber in the most economical manner" (Railway Publishing Company 1903:16). Key archaeological features that have been identified within the boundary of site 21 WA91 include foundations and footings within the sawmill's power house; the base of the mill's formerly 30-ft. tall bluff top stone chimney and its brick -lined flue that runs beneath TH 95; the stone foundation of the mill's wood -frame store/office building constructed in 1879; a storage cave; and a number of limestone retaining walls constructed to accommodate and stabilize the grade change to the rear (west) of the mill. Portions of these features are visible on the surface, including the foundations of the store and the base of the sawmill's gang saw, while others are buried. 7.3.2 Site 21WA92 (Hersey & Bean Planing Mill) Site 21 WA92 consists of the archaeological remains of the Hersey & Bean Lumber Company's planing mill or "Little Mill." This mill was constructed in 1873 to the south of the main mill and was designed to cut the long pieces of lumber that were necessary for the construction of railroad bridges. The planing mill was damaged by fire in 1887 and rebuilt on the same location. The rebuilt planing mill was described as "without doubt the most perfect and complete mill of its kind in American, and which, like Assessment of Effects / Riverbank Stabilization and Riverwalk Project Stillwater, Washington County, MN Landscape Research LLC and Two Pines Resource Group LLC / Draft 7/2020 41 their saw mill, contains the latest and most approved machinery" (Barrett 1887). In 1906, when the Hersey & Bean mill ceased operation, the machinery of the planing mill was salvaged, but the power house, which was constructed primarily of stone, was allowed to fall into ruin. The principal archaeological features of 21 WA92 are associated with the planing mill's power house and include the extant limestone walls and foundations of the boiler room, which are partially cut into bedrock, and the west walls of the machine shop and engine room (Wall Complex D). Buried aspects of the power house have also been documented. Also present is the mill's brick flue, which runs beneath TH 95. 7.4 Assessment of Effects to Archaeological Resources 7.4.1 Nelson Street E. to the Bergstein Shoddy Mill and Warehouse Between Nelson Street E. on the north and the Bergstein Shoddy Mill and Warehouse to the south, the principal feature of the proposed St. Croix Riverwalk and Stabilization project is a 10' concrete walkway (Figure 13). Near the Dock Cafe, this riverfront walk will be constructed in tandem with a concrete panel wall. From the caf6 south to the Bergstein location, riprap will be added to the shoreline and the walk will parallel the existing bituminous -paved Loop Trail. Trees removed to accommodate the walkway's construction and the placement of riprap, will be replaced with shrubs and trees coupled with a native grass and wet seed mix. Also present within this portion of the project is Overlook #1 to be constructed at the St. Croix Boat and Packet Company Loading Dock landing. This overlook will rise approximately 11' above the ordinary high-water level. The construction limits of this portion of the project are located along the shoreline between the Loop Trail and the waters of Lake St. Croix. This area is located outside the boundary of the Stillwater South Main Street Archaeological District and has not undergone previous archaeological study. A review of historic maps and historical images indicates that this section of shoreline is land created through the introduction of fill (Ruger 1870, 1879; Sanborn Map Company 1884). The expansion of the shoreline was necessary to accommodate the rail corridors that subsequently occupied this stretch of land (Sanborn 1898) (Figure 6). Other than an occasional shed or warehouse, this land area hosted rail lines and sidings into the twentieth century (Sanborn Map Company 1956) (Figure 11). Based on this review, the segment of the project between Nelson Street E. and the Bergstein Shoddy Mill and Warehouse will not impact any known archaeological sites and the area has a low potential to contain previously unidentified resources given its artificial nature and past use as a railroad corridor and yard. 7.4.2 Stillwater South Main Street Archaeological District Within the city's Bridgeview Park to the south of the Bergstein Shoddy Mill and Warehouse, the principal activities of the proposed project are the stabilization of the shoreline and the construction of two nearly identical overlooks. This work will take place within the boundary of the Stillwater South Main Street Archaeological District. Within the District shoreline stabilization may consist of either soil -filled riprap and/or vegetated erosion control mats. The proposed overlooks are each steel H-pile and concrete structures that are 20' square. The concrete exterior surface will be stained brown to blend with the surrounding environment. Black pipe -rail fencing will be installed along the perimeter of the overlooks. To prepare the area for construction, concrete and miscellaneous debris will be removed along the shoreline and trees will be taken within the footprint of the overlooks. Project plans also indicate the creation of a temporary rock Assessment of Effects / Riverbank Stabilization and Riverwak Project Stillwater, Washington County, MN Landscape Research LLC and Two Pines Resource Group LLC / Draft 7/2020 42 construction entrance along an existing access to the south of the foundations of the store/office building. Grading is limited to the immediate area of the overlooks. Rail ties along the embankment are to be protected during the removals. 7.4.2.1 Shoreline Stabilization During the Stillwater South Main Street Archaeological District's period of significance, the river's natural shoreline was modified with lumber and logs slides, platforms supported on posts, and piers (Figures 33 and 34). During the twentieth century, after the mill's closure in 1906, extensive fill was introduced to modify the shoreline, initially to increase the land area available for the rail yard of the Stillwater Municipal Barge Facility, and later to decrease the likelihood of flooding (Figure 34). The extent and depth of this fill was documented during archaeological monitoring of the installation of storm sewer during Phase 1 of the Loop Trail's construction. Whereas the present shoreline is located approximately 100 ft. east of the ruins of the mill's office building, the natural river shoreline was documented just 14 m (46 ft) to its east and at a depth of approximately 2.60 m (8.5 ft.) (Terrell 2016:21). Inland from the historic shoreline at this depth were deposits of sawdust and slab wood dating to the mill's period of operation. As the historic shoreline is deeply -buried and located inland from the present riverfront, shoreline stabilization efforts will not impact archaeological resources related to the District. Further, the proposed soil filled riprap and/or vegetated erosion control mats will be screened from the site by the tree -lined waterfront as well as the shoreline's slope and therefore will not negatively impact the District's location, setting, feeling, or association. Figure 33. Hersey & Bean Lumber Company, view to southwest, 1874. (Andreas) The main sawmill (21 WA91) is at the right and the planing mill (21 WA92) is in the background at the left Assessment of Effects / Riverbank Stabilization and Riverwak Project Stillwater, Washington County, MN Landscape Research LLC and Two Pines Resource Group LLC / Draft 7/2020 43 Figure 34. Shoreline fill is evident in this historic image of the Stillwater Municipal Barge Facility, 1939, view to south-southeast. (MNHS: Runk 2099) During this period the foundations of the former lumber company office building have been adapted to serve as switching tower and office (arrow) As an aside, it is noted that preparation for shoreline stabilization calls for the removal of "concrete and miscellaneous debris" along the shoreline. Several concrete barge moorings are located along the riverfront that, like the railroad ties to be preserved, speak to the former use of the site as a barge terminal. While some of the moorings have been undercut and displaced others remain in situ. The value of retaining some of these features as potential interpretive objects within Bridgeview Park should be considered prior to their wholesale removal. 7.4.2.2 Overlook #2 Overlook #2 is situated (approximately) 6' above the ordinary high-water line of 679.6'. The average flood elevation low water level is 676.5', so the overlook will be situated (approximately) 9' above the low- water elevation (Figure 25). According to project plans, construction impacts are limited to the overlook's footprint, surrounding shoreline riprap, and a connection between the overlook and the existing Loop Trail (AMI 2019). Overlook # 2 is located in the Stillwater South Main Street Archaeological District and within the boundary of site 21 WA91 (Hersey & Bean Sawmill). The overlook is located about 100 ft. to the east- southeast of the foundations of the 1879 store/office building. According to historic Sanborn fire insurance maps, and historic photographs, while the mill was in operation, the area between the office and the shore of Lake St. Croix was occupied by rail lines providing connections to the mill, while the Chicago, Milwaukee and St. Paul Railroad's line skirted the riverfront on a trestle. Assessment of Effects / Riverbank Stabilization and Riverwalk Project Stillwater, Washington County, MN Landscape Research LLC and Two Pines Resource Group LLC / Draft 7/2020 44 Overlook #2 is proposed for construction to the south of an existing stormwater outlet. As noted in the previous section, monitoring of the installation of that drainage line revealed that the natural shoreline dating to the District's period of significance is deeply buried and located approximately 50 ft. inland from the location of Overlook #2. Based on this assessment, Overlook #2 is located in an area of introduced fill and its construction will not impact archaeological resources related to the District. Further, the overlook is designed to be a horizontal extension of the existing landform, in an area occupied by platforms and during the mill's period of operation, and its presence will not impact on the District's location, setting, feeling, or association. 7.4.2.3 Overlook #3 Overlook #3 is situated (approximately) 3.25' above the ordinary high-water line of 679.6'. The average flood elevation low water level is 676.5', so the overlook will be (approximately) 6' above the low-water elevation (Figure 28). According to project plans, construction impacts are limited to the overlook's footprint, surrounding shoreline riprap, and a connection between the overlook and the existing Loop Trail (AMI 2019). Overlook #3 is located in the Stillwater South Main Street Archaeological District and near the south boundary of site 21 WA91 (Hersey & Bean Sawmill) and about 150 ft. north of the ruins of the planing mill's power house. According to historic Sanborn fire insurance maps, during the mill's period of operation this then narrow (-50 ft.) segment of shoreline was augmented by a planked platform that extended out into the river an additional 50 feet beyond the present shoreline. Historically, this section of the site was referred to as the "Middle Yard" and was used for the storage of lumber. Overlook #3 is proposed for construction to the immediate north of an existing stormwater outlet. The installation of this storm sewer was monitored during the Phase 1 of the Loop Trail's construction. Monitoring of the installation of this pipe run revealed deep deposits of introduced fill to the base of the excavation cut (Terrell 2016:17). Based on this assessment, Overlook #3 is located in an area of introduced fill and its construction will not impact archaeological resources related to the District. Further, the overlook is designed to be a horizontal extension of the existing landform, in an area occupied by platforms during the mill's period of operation, and its presence will not impact on the District's location, setting, feeling, or association. 7.5 Summary of Effects to Archaeological Resources Based on this assessment, the project as proposed will not have a direct effect on archaeological resources within the Stillwater South Main Street Archaeological District because planned activities will occur in areas of introduced fill. Further, beyond the District, the project area has a low potential to contain previously unidentified archaeological resources. During construction, the following measures are recommended to avoid inadvertent impacts to contributing resources to the District (Figures 35 and 36). 21 WA91 As work is planned in the immediate vicinity of the foundations of the office/store building, prior to construction the installation of temporary fencing to create a minimum 10 ft. buffer around the foundations is recommended.
