Chairman Kocon called the meeting to order at 7:03 p.m. Present: Chairman Kocon, Commissioners Collins, Fletcher, Hade, Hansen, Kelly, Lauer, Middleton, Siess, Council Representative Junker Absent: None Staff: City Planner Wittman APPROVAL OF MINUTES Possible approval of November 9, 2015 meeting minutes Motion by Commissioner Collins, seconded by Commissioner Fletcher, to approve the November 9, 2015 meeting minutes. All in favor, 9-0. Possible approval of September 9, 2015 meeting minutes Motion by Commissioner Lauer, seconded by Commissioner Hansen, to approve the September 9, 2015 meeting minutes. All in favor, 9-0. OPEN FORUM There were no public comments. PUBLIC HEARINGS Case No. 2015-40 Request for approval of a Special Use Permit for a short term rental to be located at 308 Chestnut Street East. John Atkins representing the estate of Scott Zahren, applicant. City Planner Wittman explained that the applicant is requesting a Special Use Permit for the conversion of a second story apartment into an overnight lodging unit. Two parking spaces would be required. The owner has indicated that one parking space is currently being leased at the Shorty's parking lot, a block to the west. Staff recommends approval with four conditions. Chairman Kocon opened the public hearing. John Atkins, applicant, stated he is appearing under difficult circumstances. He understands and is willing to comply with all Special Use Permit requirements including the payment of lodging taxes. The rental began shortly after July 4; its income allows the paying of legal fees, building insurance, Planning Commission December 9, 2015 utility costs, and settlement of debts while ensuring The Wedge & Wheel, the first floor tenant, is not adversely impacted. Chairman Kocon closed the public hearing. Commissioner Siess asked if the City Council has discussed regulation of VRBOs. Council Representative Junker replied that the Council has not discussed VRBOs in 2015. It appears there are other spaces downtown that could easily be converted, so he felt it warrants Council discussion. Motion by Commissioner Middleton, seconded by Commissioner Hansen, to approve a Special Use Permit for a short term rental to be located at 308 Chestnut Street East, with conditions recommended by staff. All in favor, 9-0. UNFINISHED BUSINESS Yard Parking - Survey Results and Ordinance Direction City Planner Wittman stated that at the Commission's last regularly scheduled meeting, the Commission discussed yard parking and directed staff to solicit public input. Ms. Wittman recapped that discussion. She summarized survey results. Generally, those surveyed do not park on their lawns and do not think yard parking is a problem in Stillwater but would like to see it regulated. Staff expects to present a draft ordinance for Commission consideration in January. Commission consensus was to accept the definition of a vehicle proposed by staff, with the possible addition of work equipment as suggested by Chairman Kocon. Commissioners voiced agreement with the maximum driveway width at the curb being 16'. Ms. Wittman noted that parking pads could be defined as a 10' x 30' asphalt or gravel area. Chairman Kocon suggested if the City regulates the percentage of impervious surface on a property, there also should be regulation of driveway and parking pad installation. He stated that he would like to see a permit required for installation of a new driveway or other impervious surface on a property, including sport courts. Commissioner Hansen countered that the existing impervious surface restrictions could be used as the regulating factor. Chairman Kocon pointed out that if the percentage of impervious surface is the only control, then a property owner with a very large lot could install an overly large parking pad. City Planner Wittman added that not all residential districts have maximum impervious surface coverage restrictions. Commissioner Hansen asked if the ordinance could specify a square footage allowed rather than specific dimensions of 10' x 30'. He encouraged the Commission to think outside the box because not all properties are the same. An ordinance needs to consider all types of property in the City. The Commission agreed that there should be a square footage maximum and that a property owner should not be permitted to increase the amount of impervious surface beyond the maximum allowed in the district. Page 2 of 5 Planning Commission December 9, 2015 City Planner Wittman asked how the Commission felt about setbacks. Consensus on the Commission was that the sideyard area should have a minimum setback. Commissioner Hansen asked if there would be a way to grant variances to the restrictions being discussed. Ms. Wittman replied that a property owner may apply for a variance to zoning restrictions pertaining to a number, but not for a completely different use than allowed in the district. Commissioner Fletcher said it was apparent from reading survey comments that there are a lot of people concerned about the issue. She pointed out that because enforcement is complaint -driven, even if the rules are put in place, they may not be enforced unless someone is complaining. City Planner Wittman confirmed that the City does not have a dedicated zoning enforcement officer, so staff may not be aware of a violation. Commissioner Kelly commented if a parking pad has to be contiguous to a driveway then he assumed no parking would be allowed in the rear yard either. He mentioned that the survey speaks strongly toward parking in rear yards being just as big a problem as parking in front yards. Commissioner Fletcher said she was less concerned about regulating parking in the rear as it impacts fewer people than front yard parking which is visible to anyone traveling on the street. Commissioner Hansen noted he felt strongly that the approach should be as minimal as possible to start off, such as simply prohibiting parking on the grass in the front yard. He felt the number of properties in question is so small, it doesn't warrant going through a bunch of steps to regulate. Council Representative Junker voiced concern about categorizing gravel as an improved surface; throwing some gravel down beside a garage should not be considered an improved surface. Chairman Kocon said he doesn't envision allowing someone to throw down a bucket of gravel on their grass and consider it improved, but that gravel can be considered an improved surface if done right. Commissioner Kelly said if the City regulates only the front and side yards, it will likely push the problem to the back yard, as people will probably park their RVs in the backyard. Chairman Kocon agreed he would not want to see a huge RV parked in his neighbor's backyard. Commissioner Middleton asked if a parking pad is contiguous in the front yard, isn't it just really an enlargement of the driveway? He said he would prefer setting a maximum allowable square footage of impervious surface coverage, rather than designating 10' x 30' as the maximum space for a parking pad. Commissioner Kelly suggested, in zoning districts where there are no restrictions, limiting the driveway to the width of the garage plus a maximum additional 30' x 10' or an extra 300 square feet and also restricting the setbacks. City Planner Wittman asked if the Commissioners' intent would be to regulate what is visible from the street as opposed to what is visible to the neighbors. Chairman Kocon suggested taking a straw poll. Commissioner Hade remarked it's human nature that a property owner will put a vehicle on the lot line, not next to their own house - that's why setbacks are needed. Page 3of5 Planning Commission December 9, 2015 Chairman Kocon called for a straw poll to find some measurables, for instance, a driveway can't be wider than a garage and a property owner may add 300 square feet of parking pad contiguous to the garage as long as the driveway and the parking pad do not encroach into the setback. Also, the maximum impervious surface for the lot may not be violated. Commissioner Hansen suggested first establishing that this will be a zoning ordinance, that it should be drafted in a way that allows for variances, otherwise it will create rules that some people won't be able to meet. He added that he would like to build in a relief valve for those who seasonally park in their yard to avoid parking on the street. City Planner Wittman pointed out that the violation of parking on grass would be covered under the nuisance ordinance City Planner Wittman summarized the discussion: generally speaking, the Commission would like to see the front yard area reserved for parking as opposed to the back yard; no more than 50% of the front yard to be impervious, as long as it doesn't exceed the maximum impervious surface coverage for the property; the Commission is not opposed to seeing a parking pad alongside a garage as long as the maxim;um front and side yard impervious surface coverage is not exceeded and it doesn't encroach into a sideyard setback area; concrete and asphalt are considered improved surfaces; the Commission would like to allow for provisions for variances for placement and width of parking pads; there may be other materials the Commission could consider to be impervious surface. Commissioner Middleton expressed concern that if there is no permit process, the situation becomes more a matter of relationship with one's neighbors. On a straw vote of whether a permit should be required to put in a new driveway or a parking pad, all Commissioners felt a permit should be required, except Commissioner Hansen. City Planner Wittman informed the Commission she had enough direction to draft an ordinance for the Commission's consideration. The ordinance would cover new construction or changes to impervious surface coverage; it would not apply to existing non -conforming situations. Commissioner Middleton brought up Chairman Kocon's concern, expressed in the November meeting, about the mass of vehicles. For instance, a '65 Corvette has less impact than a big hulk of an RV. He asked why the Commission isn't dealing with the issue of mass. City Planner Wittman acknowledged unless length times width times height is specified, there is no way to address mass. STAFF UPDATES System Statement City Planner Wittman informed the Commission that the Comprehensive Plan update is beginning She presented a memo indicating that the City Council has accepted the Metropolitan Council's System Statement, after clarification from Metropolitan Council staff about anticipated rural residential development patterns. Commissioner Hade asked if there has been further talk of better bus service for Stillwater. Ms. Wittman replied that the Met Council's Thrive 2040 plan includes a goal of daily service to Stillwater 6-8 times per day. ADJOURNMENT Page 4 of 5 Planning Commission December 9, 2015 Motion by Commissioner Hansen, seconded by Commissioner Fletcher, to adjourn the meeting at 8:55 p.m. All in favor, 9-0.

PLANNING REPORT MEETING DATE: January 13, 2016 CASE NO.: 2016-1 APPLICANT: Ron Laughlin, BWBR on behalf of Tony Willgert, ISD #834 REQUEST: Request for an amendment to a Special Use Permit for mechanical upgrades to the elementary school located at 6355 Osman Avenue ZONING: RA - One Family COMP PLAN DISTRICT: LDR - Low Density Res. PREPARED BY: Abbi Jo Wittman, City Planner APPLICANT REQUEST The applicant is requesting an amendment to an existing Special Use Permit for the installation of a new 160 ton chiller to be located on the north side of the Oak Park Elementary School. The (approximately) 19' long, 8' wide , and 8' tall unit will be enclosed in a 36'long, 23' wide and 10' tall area. The inside of the chiller yard will contain concrete 'hush quilt' material. The exterior of the enclosure will be a reinforced brick masonry product. The brick appearance will have the same color and tone as the existing structure. APPLICABLE REGULATIONS AND STANDARDS Municipal Code Section 31-207 indicates the following must be determined by the Planning Commission prior to the issuance of (or for an amendment to) a Special Use Permit: (1) The proposed structure or use conforms to the requirements and the intent of this chapter, and of the comprehensive plan, relevant area plans and other lawful regulations; Zoning Ordinance - There are no elements of the proposal in conflict with the Zoning Ordinance. The installation of the improvement will adhere to all district setbacks, coverage area restrictions and affects no changes to the parking calculations. Comprehensive Plan - The addition is not in conflict with the Comprehensive Plan. (2) Any additional conditions necessary for the public interest have been imposed. (3) The use or structure will not constitute a nuisance or be detrimental to the public welfare of the community. The largest concern for the installation of new mechanical equipment in this residential district is the noise generated. The applicant has supplied data showing the lining of the walls will help reduce the noise generated. At an approximate distance of 100' to the nearest property line (on the East), the sound generated will be 43 dBA. The maximum noise level for nighttime in this residential district is 55 dBA. As such, the applicant has demonstrated the amendment will not be a nuisance to the public. ALTERNATIVES, FINDINGS, AND RECOMMENDATION The Planning Commission has the following options available: 1. Recommend that the City Council approve the Special Use Permit with the following conditions: a. The exterior facade of the enclosure shall be of the same or complimentary color and tone as the existing building facade. 2. Recommend that the City Council deny the Special Use Permit. 3. Table the request for more information. Staff finds that if certain conditions are met, the proposed SUP amendment will conform to the Special Use Permit provisions. Therefore, staff would recommend the Planning Commission make a recommendation of conditional approval to the City Council.

PLANNING REPORT MEETING DATE: January 13, 2016 CASE NO.: 2016-2 APPLICANT: Ron Laughlin, BWBR on behalf of Tony Willgert, ISD #834 REQUEST: Request for an amendment to a Special Use Permit for mechanical upgrades to the elementary school located at 2003 West Willard Street ZONING: RA - One Family COMP PLAN DISTRICT: LDR - Low Density Res. PREPARED BY: Abbi Jo Wittman, City Planner APPLICANT REQUEST The applicant is requesting an amendment to an existing Special Use Permit for the installation of a new 160 ton chiller to be located on the north side of Lily Lake Elementary School. The (approximately) 19' long, 8' wide , and 8' tall unit will be enclosed in a 36'long, 24' wide and 10' tall area. The inside of the chiller yard will contain concrete 'hush quilt' material. The exterior of the enclosure will be a reinforced brick masonry product. The brick appearance will have the same color and tone as the existing structure. APPLICABLE REGULATIONS AND STANDARDS Municipal Code Section 31-207 indicates the following must be determined by the Planning Commission prior to the issuance of (or for an amendment to) a Special Use Permit: (1) The proposed structure or use conforms to the requirements and the intent of this chapter, and of the comprehensive plan, relevant area plans and other lawful regulations; Zoning Ordinance - The installation of the improvement will adhere to all district setbacks and coverage area restrictions. While the installation of this improvement will necessitate the removal of seven parking spaces, the applicant has indicated there is a surplus of 49 parking spaces on this property. Consequently, there are no elements of the proposal in conflict with the Zoning Ordinance. Comprehensive Plan - The addition is not in conflict with the Comprehensive Plan. (2) Any additional conditions necessary for the public interest have been imposed. (3) The use or structure will not constitute a nuisance or be detrimental to the public welfare of the community. The largest concern for the installation of new mechanical equipment in this residential district is the noise generated. The applicant has supplied data showing the lining of the walls will help reduce the noise generated. At an approximate distance of 50' to the nearest property line (on the East), the sound generated will be 49 dBA. The maximum noise level for nighttime in this residential district is 55 dBA. As such, the applicant has demonstrated the amendment will not be a nuisance to the public. ALTERNATIVES, FINDINGS, AND RECOMMENDATION The Planning Commission has the following options available: 1. Recommend that the City Council approve the Special Use Permit with the following conditions: a. The exterior facade of the enclosure shall be of the same or complimentary color and tone as the existing building facade. 2. Recommend that the City Council deny the Special Use Permit. 3. Table the request for more information. Staff finds that if certain conditions are met, the proposed SUP amendment will conform to the Special Use Permit provisions. Therefore, staff would recommend the Planning Commission make a recommendation of conditional approval to the City Council.

The total existing availablilty is considered to be 112 parking spaces. Refer to the attached aerial photo. • Lily Lake Elementary School has 21 designated classrooms. Based on the zoning requirement for 3 parking spaces per classroom, Lily Lake Elementary School is required to include 63 parking spaces. • The proposed chiller enclosure placement would directly eliminate 4 parking spaces and indirectly eliminate another 3 spaces, unless they are relocated through re -striping of available space. At most the number of available parking spaces would reduce from 112 to 105 parking spaces, which exceeds the required minimum number by 49 spaces. \\05cfs01VProd \1429890V06-IssuedVCity of Stillwater - Special Use Permit Submittal VLily Lake ES ApplicationVLily Lake ES_Parking Impacts Memo docx CT LILY LAKE ELEMENTARY: 21 Classrooms (63 Required Stalls) Uwater THE OIFITHPTACE OF MINNESOTA. PLANNING REPORT MEETING DATE: January 13, 2016 CASE NO.: 2016-3 APPLICANT: Ron Laughlin, BWBR on behalf of Tony Willger, ISD #834 REQUEST: Request for an amendment to a Special Use Permit for mechanical upgrades to the junior high school located at 523 Marsh Street West ZONING: RB - Two Family COMP PLAN DISTRICT: LMDR - Low Medium Density PREPARED BY: Abbi Jo Wittman, City Planner APPLICANT REQUEST The applicant is requesting an amendment to an existing Special Use Permit for the installation of a new 160 ton chiller to be located on the north side of Stillwater Junior High. The (approximately) 19' long, 8' wide , and 8' tall unit will be enclosed in a 59' long, 25' wide and 10' tall area. The inside of the chiller yard will contain concrete 'hush quilt' material. The exterior of the enclosure will be a reinforced brick masonry product. The brick appearance will have the same color and tone as the existing structure. APPLICABLE REGULATIONS AND STANDARDS Municipal Code Section 31-207 indicates the following must be determined by the Planning Commission prior to the issuance of (or for an amendment to) a Special Use Permit: (1) The proposed structure or use conforms to the requirements and the intent of this chapter, and of the comprehensive plan, relevant area plans and other lawful regulations; Zoning Ordinance - The installation of the improvement will adhere to all district setbacks and coverage area restrictions. However, the installation of this improvement will necessitate the removal of parking spaces from this centralized location. The applicant is proposing the removal of five parking stalls on the east of this 14-stall parking lot, retaining the western stalls in an angled fashion. The proposed configuration of these parking spaces does not meet the design requirements set forth in City Code Section 31-510, Off-street parking and loading. As such, staff has determined there will be a loss of 11 parking spaces. In a 2011 parking analysis conducted for the issuances of a Use Permit for the Early Childhood Family Center, it was determined a total of 337 parking spaces would be required for the two uses. As the applicant indicates, there are 357 parking spaces onsite. With the reduction of the aforementioned parking spaces, there will still be a surplus of nine parking spaces off-street parking spaces. Consequently, there are no elements of the proposal in conflict with the Zoning Ordinance. Comprehensive Plan - The addition is not in conflict with the Comprehensive Plan. (2) Any additional conditions necessary for the public interest have been imposed. (3) The use or structure will not constitute a nuisance or be detrimental to the public welfare of the community. The largest concern for the installation of new mechanical equipment in this residential district is the noise generated. The applicant has supplied data showing the lining of the walls will help reduce the noise generated. At an approximate distance of 100', the sound generated will be 49 dBA. The nearest property line is greater than 500' from this proposed improvement. As such, the applicant has demonstrated the amendment will not be a nuisance to the public. ALTERNATIVES, FINDINGS, AND RECOMMENDATION The Planning Commission has the following options available: 1. Recommend that the City Council approve the Special Use Permit with the following conditions: a. The exterior facade of the enclosure shall be of the same or complimentary color and tone as the existing building facade. 2. Recommend that the City Council deny the Special Use Permit. 3. Table the request for more information. Staff finds that if certain conditions are met, the proposed SUP amendment will conform to the Special Use Permit provisions. Therefore, staff would recommend the Planning Commission make a recommendation of conditional approval to the City Council.

To support these upgrades two air-cooled chiller units are required to be located on grade outside of the building envelope. These chiller units will be visually concealed within a 10' high enclosure, with a double leaf gate provided for maintenance access. Both enclosure and gate will be lined with sound attenuating blankets, to improve acoustic isolation of the chiller. The project also includes finish revisions within classrooms surrounding the auditorium located in the south wing.

Refer to the attached aerial photo. • Stillwater Junior High School has 68 designated classrooms while the Early Childhood Family Center has 21 designated classrooms for a combined total of 89 classrooms. Based on the zoning requirement for 3 parking spaces per classroom, these two facilities are jointly required to provide 267 parking spaces. • The proposed chiller enclosure placement would directly eliminate 7 existing parking spaces, reducing the number available from 357 to 350 parking spaces, exceeding the required minimum number by 83 spaces. \\05cfs01VProd\1429890V06-IssuedVCity of Stillwater - Special Use Permit Submittal\Stillwater JH Application \Stillwater 1H_Parking Impacts Memo docx STILLWATER JUNIOR HIGH: 50 Primary Classrooms (150 Minimum Required Stalls) I 18 Ancillary Classrooms (204 Maximum Required Stalls) PLANNING COMMISSION MEETING DATE: January 13, 2016 CASE NO.: 2016-4 REGARDING: Consideration of adoption of new regulations pertaining to parking vehicles on yard areas. PREPARED BY: Abbi Jo Wittman, City Planner BACKGROUND During the last few meetings the Commission has discussed potential regulations pertaining to the parking of vehicles in yard areas. As a reminder, the City Council tasked the Commission with this as to start eliminating the visual blight that occurs when property owners park vehicles on grass and lawn areas. PROPOSED ORDINANCE AND COMMISSION DISCUSSION Staff is proposing the attached modifications to the City Code pertaining to the standards and regulations for parking on yard areas; please see the legislative version for a complete description of all modifications proposed. As the Commission will notice, the proposed ordinance does not address parking pads, maximum parking pad size nor any specific reference to where a parking pad may be located. In drafting the ordinance, staff aimed to work within the existing off-street parking and loading regulations to the greatest extent possible. In doing this, staff was able to make minimal modifications to the regulations while meeting the direction of the City Council. Attached to this memo is a legislative version of City Code Section 31-510, Off-street parking regulations. Staff has highlighted current code provisions which support the prohibition of parking on lawn and yard areas. Specifically, this Code Section clearly indicated surfacing materials shall be concrete or bituminous. While this has been in place in the code, and therefore is applicable to all properties, there was no provisions in place tying these design standards to everyday activities but only making the provisions applicable at the time of new development. Therefore, when coupled with the addition that "[p]arking vehicles in the Front or Side Yard area of all districts, with the exception of the Agricultural Preservation (AP) district, shall be in conformance with the requirements in this Section 31-510," the City will have codified the direction provided by the City Council. While not indicated above, the draft ordinance does also include the creation of a driveway permit. Details of what would be required for the driveway permit approval do not need to be codified however, if the provision for driveway permits is adopted, a modification to the City's fee schedule will need to be made. Additionally, is has yet to be determined which In discussions with the Public Works and Engineering Department, Public Works Director Shawn Sanders indicated it may be good to have a permit like this but questioned whether or not instituting this type of permit at this time was most appropriate as well as who would administer the permit review process. Sanders indicated that driveway specifications and standards are found in various sections of the City Code and they they are not as comprehensive as the City may desire (such as there is no provision indicating separation between driveways, the standards for driveway widths, nor the requirements for assessing surface water runoff from new driveway construction). Sanders recommended the City explore the development of comprehensive driveway development standards prior to requiring new permits. After opening the public hearing, the Commission should discuss whether or not the proposed ordinance addresses the concerns of the Commission. The Commission should take action on the proposed ordinance. ALTERNATIVES The Commission may: 1. Provide a favorable recommendation of approval of the draft ordinance, as written, to the City Council. 2. Provide a favorable recommendation of approval of the draft ordinance, with specific modifications, to the City Council. 3. Table consideration of the draft Ordinance and direct staff to modify the ordinance to be brought back before the Commission at their next regularly scheduled meeting.

Modifications to off-street parking and loading requirements shall be permitted as follows: (1) Alternative provisions. The off-street parking requirements of this subdivision shall be considered satisfied if: Draft Legislative Version (Yard Parking Ordinance), Page 1 of 7 i. The property being occupied is a part of a parking district which has been duly formed under the provisions of this Code; and ii. A specific development plan for an area has been adopted and contains parking standards which supersede those contained in this subdivision; or iii. The required parking spaces and street access are permanently provided within 300 feet of the parcel, and a maintenance and management plan indicating the useful functioning of such parking is submitted and approved by the community development director. Not more than 60 percent of the required parking may be provided off the site. (2) Cooperative parking facilities. The requirements for the provisions of parking facilities, with respect to two more property uses of the same or different types, may be satisfied by the permanent allocation of the required number of spaces for each use in a common parking facility, located within 300 feet of all such participating property uses and cooperatively established and operated. In the case of a cooperative parking facility which is designed to satisfy the parking requirements of: i. From two to four independent property uses, a reduction of not more than five percent of the total number of required spaces shall be allowed. ii. From five to seven independent property uses, a reduction of not more than ten percent of the total number of required spaces shall be allowed. iii. Eight or more independent property uses, a reduction of not more than 20 percent of the total number of required spaces shall be allowed. Shared parking facilities. Parking facilities may be shared by two or more commercial uses if their entrances are located within 300 feet of each other and if their hours of operation do not coincide, provided they: i. Receive special use and design permit so that design criteria are met and conditions of use may be established along with periodic review. ii. Submit a written document guaranteeing maintenance, hours of operation and specifying length of agreement. iii. Demonstrate how the shared parking arrangement will fulfill the intent of this subdivision. (3) (4) Parking requirements for nonconforming structures or uses. In the case of structures in any district, which are reconstructed, enlarged, structurally altered, changed in occupancy to a more intensive use category or otherwise increased in capacity, off-street parking shall be provided only for that portion of structures or use constituting the increase in capacity; except that no additional parking need be provided for nonresidential uses, if the increased capacity results in an increase of four or fewer off-street parking spaces. (e) Miscellaneous requirements. Miscellaneous parking and loading requirements are as follows: (1) Parking limit. The city may establish a maximum parking limit where the development proposal exceeds city standards for the number of parking spaces required. (2) Parking use. Parking areas shall be used for vehicle parking only with no Draft Legislative Version (Yard Parking Ordinance), Page 2 of 7 (3) sales, dead storage, repair work or dismantling of any kind.
