NORTH AIPLE PARK
Property Features
0.6 mile of St. Croix River
shoreline
• 15 acres total
• Grotto and natural seeps
along the rocky bluffs lining
the west side of the property
• Pond on the north side of
the property with foot path
around its circumference
• Aiple residence (1960s home
situated in the middle of the
property with views of the
river)
CONSERVATION
EASEMENT
Washington County holds a
Conservation Easement over
the Aiple property which limits
development of the site. Of note
are the following requirements:
The City agrees to develop
the site as a public park,
restore much of the property
to natural conditions, provide
passive recreational uses,
complete a management
plan, and own and maintain
the property.
There is to be no
development on the site
that increases the amount of
impervious surface on site.
INTRODUCTION &
PROJECT BACKGROUND
PROJECT PURPOSE
This planning document is meant to guide the future development and
vegetation management for the City of Stillwater's North Aiple Park
property located on the St. Croix River. Guided by the approved concept
plan and in compliance with the property's conservation easement,
the master plan utilizes community input regarding site needs and
improvements as well as outlines, in detail, the vegetation management of
the site.
This master plan builds upon work that was completed in 2017 to create
an updated conceptual master plan for the site. Recommendations in
the previous plan include a connection to the Brown's Creek State Trail,
addition of an ADA accessible fishing pier, additional loop trails throughout
the park, interpretive signage and trailhead facilities, and restoration
of vegetation and natural shoreline improvements. The current master
planning process has evolved those recommendations and considers
potential reuse of the existing building on the site.
SITE CONTEXT
North Aiple Park is located in northeast Stillwater, along the St. Croix River.
The Brown's Creek State Trail runs along the west side of the property.
Minnesota State Highway 95 runs north and south along the west side of
the property and provides vehicular access to the site. Historic downtown
Stillwater is located less than one mile south of the park site. The property
includes over half a mile of river shoreline, with a sandy beach located near
the Aiple residence.

TIMELINE OF NORTH AIPLE PARK'S HISTORY
500,000,000 Years Ago:
Shallow seas deposited
sand and sediment that
formed the bedrock
we see today: marine
sandstones, shales,
and limestones from
the Cambrian and
Ordovician periods.
10,000 Years Ago:
The St. Croix River served
as a major drainage for
glacial melt waters.
Native Americans began
occupying the St. Croix
River valley.
Greg Seitz I St. Croix 360
Late 1600s:
Native Americans maintain a
presence in the area.
The name St. Croix for the river
is first recorded. Many stories
concerning the name St. Croix link
it to the early French missionaries,
or to a French fur trader who died
at the river's mouth.
March 4, 1854:
The City of Stillwater is
founded.
This year, the Schulenburg
and Boeckeler Lumber Mill is
constructed on site (burned
down in 1877).
PREHISTORY
Not to scale
1000 YEARS
AGO
1,000,000 - 14,000 Years
Ago:
At least 4 glacial epochs
deposited additional silt
and sand, while ice and
water shaped and wore
away the rock formations
in the St. Croix River valley
17th-19th Century:
The St. Croix River was a
favored fur trade route from
the Mississippi River to
Lake Superior. In 1838, the
Tamarack House was built
by Joseph Renshaw Brown,
known as a forefather of
Stillwater.
1837:
A treaty opened the area to
settlement by Euro-Americans.
1884-1888:

PREVIOUS PLANNING
In 2016 and 2017, the City conducted a process to evaluate site conditions
and develop a preliminary site concept plan. Input from stakeholders, City
staff and elected officials helped develop the high level concept for the
property. Recommendations in the previous plan included a connection
to the Brown's Creek State Trail, addition of an ADA accessible fishing
pier, additional loop trails throughout the park, interpretive signage and
trailhead facilities, and restoration of vegetation and natural shoreline
improvements.
The previous concept plan can be found in the Appendix of this document.
PUBLIC & STAKEHOLDER ENGAGEMENT
Engagement & Input
Stakeholder Meeting
A meeting was held at Stillwater City Hall on March 5, 2020, with
representatives from local, state, and national agencies who were invited
to provide input on the previously developed concept and discuss
implementation of potential improvements. Notable considerations
include:
• For the Wild and Scenic River designation, anything under the High
Water Level mark needs NPS review before construction.
• The National Park Service and the St. Croix River Association are
interested in seeing a kayak/canoe launch on the site as this is a missing
amenity in Stillwater, and it would be used by educational programs.
• There are potential partnership and funding opportunities for trail
connections and kayak/canoe facilities through federal and state (DNR)
grants.
• Priorities for the future of the site are to not degrade it, but rather
improve the natural vegetation and landscape, and to provide a place
where people can "touch the river" in Stillwater.

What's Going On?
Over the next year, the City of Stillwater is creating a
master nb
r North Piple ark. Themaster plan will
include al long-range vision for the park and guide future
decisions about park activities, capital investments,
potential reuse of the existing building, and natural
resource restoration. Initial conceptplanning for the then newly acquired
property °ccured In Cie J. The project team Is soliciting
feedback on this concept plan In order to begin to
evolve the design.

NORTH AIPLE PARK MASTER PLAN
• There is interest in screening the shoreline by planting natural
vegetation in places where the lawn is exposed to the river.
• Low impact and low profile structures should be considered for any
future facilities and amenities on the site.
Online Engagement
General public engagement was conducted online with an online
interactive mapping tool (Social Pinpoint) with complementary survey
questions. The Social Pinpoint site presented the 2017 Concept Plan for
the North Aiple Park property and asked viewers to provide comments on
the map by dragging pins to geographic point and providing associated
comments. The page also included a short survey asking the following
questions:
• What proposed park features do you like?
• What elements do not make sense?
• Do you have specific thoughts or ideas on other ways you'd like to use
the park?
The Social Pinpoint page was open during the month of February, 2020,
and received 7,515 total site visits to the page; 87 comments provided on
the site map and previous concept plan; and 105 responses to the survey
questions.
Overall there was high interest expressed by public input in paddle sports,
passive recreation (including hiking trails along the river), beach access,
fishing, and restoration. When asking about the importance of preserving
and reusing the existing building on the site, greater than 50% indicated
preservation of the house was 'important' or'very important There
was also interest expressed in adding amenities for park users, such as
restrooms, picnic facilities, and seating or overlook areas. Most survey
respondents desire natural vegetation and restoration to be employed
throughout the site to keep a feeling of natural beauty, peace, and quiet.
There was mixed input on parking on the site. Generally, respondents think
the site should be accessible for all ages and abilities, but are concerned
that providing parking
will create overuse of the
park.
Detailed survey
responses can be found
in the Appendix.

DEVELOPMENT PLAN
This section guides the future development of park facilities and amenities,
such as trails, picnic areas, parking areas, and structures. The overall theme
of the North Aiple Park development is passive, riverfront recreation. The
development concept plan identifies proposed features at a conceptual
level. Final implementation and construction of concept plan elements
may differ from what is shown in this plan according to issues and
opportunities that arise during the design and engineering process.
While planning development features, consideration was given to existing
infrastructure, natural site features, the desire to provide access to the river,
the desire to provide access from the Brown's Creek State Trail to the site
amenities, and requirements of the Conservation Easement.
Major development recommendations include:
• An ADA accessible kayak/canoe launch near the Aiple residence with an
adjacent sandy beach for group kayak/canoe launching
• Rehabilitation of the existing detached garage/shed to create a picnic
shelter and overlook of the groundwater -fed creek
• Accessible trails running the length of the site as well as connecting to
the Brown's Creek State Trail
• Natural surface trails through wooded areas
• Picnic areas, benches, and overlooks for river viewing and fishing, along
trails where feasible
• An individual and small group kayak/canoe launch at the southern end
of the site with stairs and potential canoe slide
• Expanded parking at the southern end of the site in partnership with
the Zephyr Theatre parking
• Rehabilitation and remodeling of the existing Aiple residence to create
an outdoor recreation focused building with public access to restrooms,
potential crew boat storage, paddlecraft rental vendor space, and picnic
patio/pavilion

AIPLE RESIDENCE
Analysis of Existing Structure
In 2016 Miller Dunwiddie was hired by the City of Stillwater to review the existing conditions of the Aiple Residence.
The report identified the existing building construction: a mid-1960s two-story walkout house with a 1.5 story
pool addition, totaling approximately 5,700 SF. The lower level walls are concrete block with a stone veneer above
grade, and wood framed walls above with horizontal wood siding. The report observed that the home was in good
condition and repair, with the following exceptions: active foundation crack at the west wall of the garage, and
uneven upper level floor above garage; insect infestation in the pool addition heavy timbers; water and moisture
below west entry and in pool pump room; and an undersized mechanical system reaching expected life.
The report then went on to note modifications that would be required to reuse the building as a public facility,
including providing ADA accessibility to each level of public use; accessible restrooms, modifications to non-
complying life -safety items (railing, hand rails, fire alarms, etc); code compliance for fire separation or fire protection
sprinkler; and upgraded mechanical and electrical. Two reuse options were presented at end of written report.
Like the 2016 evaluation determined, the 2020 updated condition survey found the home to be in good condition
with some isolated areas in need of repair. No new items were found to be of concern. ADA accessibility continues
to be an impediment for reuse, requiring modification. The proposed design addresses many of the repair and
modification items with changes to the structure. Remaining items, primarily moisture infiltration at the basement
level, would be managed through a moisture mitigation strategy determined during the design phase, but should
not be considered a deterrent for moving forward with plans to use the building.
Other items that will need to be addressed and may need further study with the future building renovation include:
removal of oil tanks on the property; removal of buried transformer near the house; and transfer of sanitary sewer
to City sewer system.

Features of the proposed floor plan:
Envelope
• Much of the existing shell (walls, roof, foundation) would remain in place. A new"upper"floor would be inserted
at entry grade level (between existing basement and upper floor levels) to eliminate accessibility concerns.
Existing basement would become a crawl space.
• Windows will be inserted at the same locations as basement windows, to utilize existing openings in the stone.
Some areas of infill or modifications would be necessary, but much of the existing stone on all elevations would
remain in place.
Upper Level
• The main level would have open gathering areas plus a kitchenette in the main part of the building.
• The fireplace/chimney would remain in the center of the building, where they are currently located.
Modifications would be required with change in floor level.
• Restrooms would be accessible from inside the building, as well as from an open-air walkway that is covered
with the existing roof. The walkway connects the east and west yards, which requires some exterior ramping to
accommodate slope changes. This exterior access to the restrooms would allow them to be used by the public
when the main building is locked.
Lower Level
• The existing garage area at the north end would become a
vendor space, and would remain at current driveway level for
ease of access and deliveries. An internal stair would connect
to main level if necessary/desired, but would not be intended
for public use.
• A gathering space would anchor the south end of the Lower
Level, provide a flexible area for a variety of programming.
Operable garage doors would be located on the south and
east elevations, to allow for open air gatherings during
comfortable weather.
• Scull storage would be provided at the lower level, with access
from the east elevation. The intention would be to have scull
storage racks on north and south walls to double load the
storage room.

VEGETATION
MANAGEMENT PLAN
OVERVIEW
Site visits were conducted by FOR staff at North Aiple Park on 1/27/20 and
2/12/20 to evaluate natural resources. The site inventory is described for
the three site characters of the park outlined in the concept plan: Nature
Exploration, Picturesque Parkland, and Disturbed Woodland. Specific
stewardship goals and management recommendations are provided.
LANDSCAPE DESCRIPTION
The North Aiple Park property consist of a thin strip of floodplain forest
along the St. Croix River. Geology of the site is dominated by relatively
shallow bedrock that is frequently exposed as outcrops. Overlying soils are
classified as sandy or gravelly, but in many areas have been disturbed via
filling and grading from historic use. Groundwater influence is strong and
several seeps are scattered throughout the site.
The North Aiple Park Concept Plan delineates the site into three sections
based on park character: Nature Exploration in the north, Picturesque
Parkland in the center, and Disturbed Woodland in the south. Overall
site topography is characterized by a generally steep, modified shoreline
grading to a narrow floodplain terrace, then transitioning to steep bluffs
rising to the Brown's Creek state trail and Highway 95. A former trout pond
is the most prominent feature of the northern area of the site (Nature
Exploration), and is formed by a steep berm adjacent to the St. Croix River.
Two human -made pools are situated above the northwestern slope of
the former trout pond and collect water from groundwater seeps. A more
gently sloping landscaped lawn with scattered trees is located in the
central portion of the site (Picturesque Parkland). The southern portion of
the site (Disturbed Woodland) includes steep banks with a disturbed, flat
upland terrace, with steep wooded bluffs along the western boundary.
A creek fed by groundwater and stormwater runs north -south along the
existing driveway and flows to the former trout pond.
NORTH AIPLE PARK MASTER PLAN
SITE INVENTORY
Existing vegetation cover was inventoried for each of the three park characters, and relevant natural resource
observations were also recorded. Vegetation cover within the Nature Exploration section was most varied and is
described according to specific locations. Management Units were outlined based on inventory results (see map on
following page).
Nature Exploration Observations
North Side of Former Trout Pond (Unit A)
• Woody vegetation appears to have been removed
from the drainage way north of the trout pond berm
relatively recently.
• The cleared area consists of weedy plant species
characteristic of recent disturbance such as
raspberry, burdock, and dock. A potential seep is
dominated by cattail.
West Side of Former Trout Pond (Unit B)
• The west side of the former trout pond represents
the most ecologically diverse area of the site due
to relatively good tree and shrub diversity, bedrock
plant communities, several groundwater seeps, and
two groundwater -fed pools.
• Although the tree and shrub community is not
especially diverse, it is diverse relative to the
remainder of the site with some hackberry,
ironwood, willow, red oak, basswood, American elm,
and pagoda dogwood.
• Woody invasives are an issue in this area, but their
abundance is buffered somewhat by the better tree
and shrub diversity.
• Exposed bedrock and groundwater seep plant
communities provide additional diversity, though
species composition could not be observed due to
timing of the site visits in winter.
• The two groundwater -fed pools (including the
"grotto") provide year-round open water. Aquatic
plants were observed growing sparsely in the north
pool.
• Aerial imagery from the early and mid-20th century
indicates that this area has been filled (possibly due
to deposition from the river and/or anthropogenic
filling). Historic boat mooring anchors were
observed in bedrock and also suggest filling in this
area.
East Side of Former Trout Pond (Unit C: Berm)
• Very steep slopes and narrow trail.
• Poor tree/shrub diversity with abundant black
locust, common buckthorn, and exotic honeysuckle.
Native trees include silver maple, cottonwood, and
green ash with some young red oak and Eastern red
cedar.
Former Trout Pond (Unit I)
• Water level within the trout pond appears low.
• Abundant leaf litter and woody debris.
• Water control structure is missing stop logs and
overall condition/function is unknown.
Picturesque Parkland Observations (Units D, E, and F)
• This area is characterized by a landscaped open
lawn, with large cottonwood and white pine and
white spruce plantings (Unit E).
• Several large black locust are located along the
driveway (Unit D and Unit E).
• White pines within the existing lawn are yellowed
and appear stressed (Unit E).
• Shoreline vegetation includes several native shrubs
including willow, dogwood, and elderberry with
box elder and green ash trees. Common and glossy
buckthorn are also present along the shoreline (Unit
F).
Disturbed Woodland Observations (Units D, G, and H)
• This area is characterized by steep banks with a
narrow strip of floodplain forest (Unit G), an upland
terrace with some groundwater seep wetlands (Unit
H), and the steep wooded slopes leading toward the
state trail (Units D and H).
• The floodplain forest consists of relatively older
silver maple, cottonwood, box elder, and green ash,
with several mature, fruiting buckthorn (Unit G).
• The upland terrace appears to have been historically
maintained as a clearing and likely storage yard
based on aerial imagery from the early and mid-20th
century (Unit H).
• The upland terrace lacks older trees and has poor
woody plant diversity. It is dominated by invasives
black locust and common buckthorn, with glossy
buckthorn and mulberry also observed (Unit H).
• Large hybrid poplars were observed on the upland
terrace near the southern extent of the park and
appear to be spreading (Unit H).
• Several groundwater seep wetlands were observed
on the upland terrace. The seeps appeared to be
more disturbed than those observed near the
former trout pond (Unit H).
• Several historic features were observed including
a wall and circular brick structure. The function of
the circular brick structure is unknown and could be
stormwater infrastructure or an old well (Unit H).
• Considerable rubble and debris used for
stabilization was observed along the shoreline.
Some rubble included potentially hazardous and
unsightly iron rebar (Unit G).

NORTH AIPLE PARK MASTER PLAN
STEWARDSHIP GOALS
AND MANAGEMENT
RECOMMENDATIONS
Six natural resource goals were identified for North
Aiple Park. Of these, two are focused on vegetation
management and the remaining four are focused
on additional assessment and natural resources
implementation. Goals and recommendations are
described below and identified by Management Units
in the map on the previous page. Cost estimates are
provided in the Implementation section.
Vegetation Management Goals
Goal 1: Control invasive plants.
Goal 2: Enhance and restore native vegetation.
Additional Assessment and Natural Resource
Implementation Goals
Goal 3: Protect sensitive groundwater seep wetlands.
Goal 4. Assess existing bank stabilization practices.
Goal 5: Highlight the natural resource value of Nature
Exploration section.
Goal 6. Assess feasibility of public trout pond.
Potential partners for management include, but are
not limited to, Washington Conservation District, MN
DNR Parks and Trails, MN DOT, Great River Greening,
Conservation Corps Minnesota, and St. Croix River
Association. Potential funding sources include, but are
not limited to, the State of Minnesota Environmental
Trust Fund, Outdoor Heritage Fund, and Clean Water
Fund.
Goal 1: Control invasive plants.
Woody invasive plants are prevalent throughout the
site with common buckthorn and black locust most
abundant. Exotic honeysuckle, glossy buckthorn, and
mulberry are also present, with aquatic invasive plant
watercress observed in the creek. Herbaceous invasive
plants such as garlic mustard were not observed during
winter but are likely present. We highly recommend
that program/use of the former trout pond and berm
(Units C and 1) are determined prior to committing
resources to vegetation management in or near these
areas.
Recommendations:
• Vegetation management near the former trout
pond (Units C and 1) should be sequenced to align
with planned park use in this area. For example,
vegetation management should take place after
potential changes to the berm, if any.
Woody invasive management (Units A, 8, C, D, G, and H):
• Management of woody invasives should target
mature, fruiting individuals to reduce seed dispersal.
Stumps should be cut and treated with herbicide
prior to re -sprouting. Stems and branches with fruits
should be carefully of disposed of so that seed is not
spread.
• Buckthorn is a prolific seeder, and areas that have
been recently cleared may quickly regenerate.
Following removal of mature individuals, seedling
control efforts will be needed. For small seedlings
less than 3/8 inch in diameter, hand -pulling or
mechanical pulling is effective. Larger individuals
will require cutting and stump treating with
herbicide.
• Flag native shrubs and tree saplings in areas of
woody invasive management to protect the native
species present.
In the upland terrace of the Disturbed Woodland
(Unit H), consider a forestry mow and herbicide
treatment in conjunction with potential prairie/
savannah restoration (see Goal 2).
• Monitor areas of invasive plant control to determine
effectiveness and assess native tree and shrub
recruitment. If native trees and shrubs fail to
colonize despite control of invasive species, consider
targeted plantings.
• See the Implementation section for estimated costs.
Woody invasive management within Highway 95 and state
trail corridor (Unit J):
Invasive woody vegetation and some potential
hazard trees were observed along the western
boundary adjacent to the state trail and extending
beyond the park boundary to the west (Unit J).
DECEMBER 1, 2020
Although much of this area is located outside the
park boundary, this area should be managed due to
its visibility from the highway and state trail.
- Manage woody vegetation adjacent to state
trail and Highway 95 to improve aesthetic and
ecological value.
• Consider partnerships with MN DNR and MN DOT to
collaboratively manage this area.
• Costs are itemized separately from other Units
as most of Unit J is not on City property. See
Implementation section for estimated costs.
Watercress management (Park -wide in creek and seeps):
• Management of watercress should focus on
preventing spread to groundwater seep wetlands
and preventing flow obstructions within the creek.
Control of watercress within the creek may not be
feasible. Watercress can be removed by hand or
mechanically. However, reestablishment is likely
without native revegetation, and establishment
of native vegetation within the creek may not be
feasible.
Costs for inventory are included in the
Implementation section. No specific management
action is recommended, but the City should be
aware of potential issues associated with watercress.
Herbaceous invasive management (Park -wide):
• Conduct an inventory of herbaceous plant cover
during the growing season.This natural resources
assessment did not assess herbaceous plant cover
due to snow cover and lack of active growth.
Herbaceous invasive species such as garlic mustard
are common to the region and may require
management.
• Potential management costs are included in
the Implementation section. Costs for complete
inventory are included in the Implementation
section.
Goal 2: Enhance and restore native vegetation.
Several areas of the site were identified for potential
vegetation restoration and enhancement activities.
These activities will improve ecological and aesthetic
value of the park.
Recommendations:
Nature Exploration (Units A, B, C, and D)
If native trees and shrubs fail to colonize despite
control of invasive species following management,
consider targeted plantings.
• Assess northern site boundary in area of recent tree
removal during the growing season (Unit A).This
area appeared disturbed during the site visits but
assessment was limited due to snow cover and lack
of active vegetation growth. Vegetation restoration
opportunities in this area could be integrated with
stormwater practices and buffering of residential
use to north.
• Estimated costs are included in the Implementation
section.
Picturesque Parkland (Units E & F):
• Remove ecologically unsuitable (white spruce) and
stressed conifers (white pine) within the Picturesque
Parkland (Unit E).
Remove white spruce to reflect more appropriate
native plant communities to the region.
Assess tree health and potential removal of white
pines. Although large white pines are ecologically
appropriate to the St. Croix River Valley, the white
pines on site appear stressed and may be too close
to the water table.
• Enhance the existing shoreline of the Picturesque
Parkland lawn area where few shrubs and little
buffer is present (Unit F).
- Plant cuttings of native shrubs such as willow and
dogwood along shoreline. Plantings should include
a pollinator friendly buffer.
Integrate pollinator friendly plantings in open areas
(primarily Picturesque Parkland) where compatible
with park use (Unit E).
• See Appendix A: Table 3 for estimated costs.
Disturbed Woodland (Units H and G):
If native trees and shrubs fail to colonize despite
control of invasive species following management,
consider targeted plantings.
• Restore the upland terrace of the Disturbed
Woodland to prairie or savannah plant community
(Unit H).
- Consider a forestry mow and herbicide treatment
to remove invasives and prepare the site for
restoration.
NORTH AIPLE PARK MASTER PLAN
- Consider large scale seeding/planting of prairie or
savannah vegetation to provide pollinator habitat
and restore a native plant community.
- Consider the recommendations of the Phase
I ESA prepared for the site when planning for
potential soil disturbance. Assess soil suitability for
supporting native vegetation.
• Estimated costs are included in the Implementation
setion.
Additional Assessment and Natural Resource
Implementation Goals
Costs for additional assessment recommendations
are estimated as lump sum (Appendix A: Table 4).
Costs for additional natural resource implementation
recommendations are highly variable depending on
scope and design and therefore are not provided at this
time.
Goal 3: Protect sensitive groundwater seep wetlands.
Groundwater seeps have soft soils sensitive to
disturbance and may harbor unique native plant
communities.
Recommendations (Park -wide):
Assessment:
• Inventory and map groundwater seeps throughout
the park.
• Conduct wetland delineations in areas where
specific plans will be advanced to comply with local,
state, and federal protections.
Natural Resource Implementation:
• Design park infrastructure to discourage or prohibit
foot -access to seeps.
Goal 4. Assess existing bank stabilization practices.
Considerable rubble and debris used for stabilization
was observed along the shoreline. Banks are very steep
within the Disturbed Woodland section.
Recommendations (Unit G):
Assessment:
• Consider selective removal of rubble and debris
where feasible.
Natural Resource Implementation:
• Perform an assessment of existing banks in Unit G
(Disturbed Woodland). Long-term planning could
include more visually appealing bank stabilization
practices.
Goal 5: Highlight the natural resource value of Nature
Exploration section.
The west side of the trout pond is a natural resources
strength and could be used an interpretive
opportunity (Units B and 1). This is solely a conceptual
recommendation and costs are not provided.
Recommendations (Units B & I):
Interactions between groundwater and surface
water (e.g. seepage, pooling, stream on south end of
trout pond, St. Croix River) are currently accessible
and could be highlighted further.
• Bedrock and seep communities provide access to
unique plant communities and should be preserved
and protected.
Goal 6. Assess feasibility of public trout pond
The reuse of the former trout pond for public trout
fishing is an intriguing re -use of existing park elements,
but requires careful consideration of technical and
regulatory feasibility.
Recommendations (Unit I):
Assessment:
• Conduct a feasibility assessment that includes, but is
not limited to, the following considerations:
- ADA-accessibility, particularly along narrow trail
and steep slopes of east berm. Will it be necessary to
lower berm and increase width?
- Functional integrity of the berm (e.g. water
tightness, stability)
- Functional integrity of the water control structure
- Bathymetry and sediment deposition of the pond
(how deep is the basin?)
- Sustainability of public trout fishery (what
population size could it support?)
- Aquatic invasive species issues with St. Croix River
and stocking (could AIS be introduced from stock?)
- Correspondence with DNR Fisheries Division
regarding stocking regulations

IMPLEMENTATION &
COST ESTIMATES
PHASING
Improvements to the North Aiple Park property will be developed and
constructed over time as opportunities arise and funding allows. This
chapter identifies phasing projects according to a general timeline:
• Short Term:These are high priority projects that will allow access and
limited public use of the site. These are also projects that need to be
completed prior to other projects. The timeline for Short Term projects
is 0-5 years, but some projects could be completed later if funding does
not allow completion within five years.
• Mid Term:These are highly desired projects that may be more expensive
than Short Term projects or need other site work to occur before they
can be constructed. The timeline for Mid Term projects is 3-10 years.
• Long Term: Large projects that require more engagement and planning
are in this category. These projects are also typically more expensive
than Short Term and Mid Term projects.The timeline for Long Term
projects is 10+ years, but if opportunities arise with partnerships or
funding, these projects may be constructed sooner.

VEGETATION MANAGEMENT PHASING & COST ESTIMATE
Total management costs were based on 10-year management plans. Total 10 years costs for all vegetation
management are $165,516. Cost estimation is based on:
a) 2020 dollars,
b) subcontracting all implementation and necessary oversight, and
c) assumption that all Management Units are implemented concurrently.
Management units have varying amounts of invasive species cover and therefore varying management inputs/
costs, but for simplicity costs are averaged across Units.

POTENTIAL FUNDING
OPTIONS, SOURCES, AND
PARTNERS
National Park Service
The National Park Service (NPS) manages river access
at several points along the St. Croix National Scenic
Riverway. The NPS and the St. Croix River Association
manage K-12 programs together ("Rivers are Alive"),
and they would like to have a place in Stillwater where
kids can touch the river.
NPS may be interested in a partnership with a canoe/
gear rental stand (would authorize outfitters with a
commercial use permit).
Gateway Communities
Cities or towns that lie just outside major national
tourist attractions are called Gateway Communities.
Stillwater or North Aiple Park could be positioned as
a Gateway Community to the St. Croix River in order
to potentially be considered for funding for river
recreation facilities.
St. Croix River Association
The St. Croix River Association (SCRA) is an official
nonprofit partner with the National Park Service. The
SCRA works closely with the NPS on programs; they
work with 6,000 K-12 kids annually. Programs include
paddling and outdoor education on the river. The SCRA
may be a funding partner for a kayak/canoe launch
on the property and an indoor outdoor education/
programming facility at the park.
Federal Lands Access Program
The Federal Lands Access Program (FLAP) may have
funding to support a paddle launch on the North Aiple
property because it would be a linkage to the river.
A grant proposal should be crafted to position North
Aiple Park as a place of access (gateway) to the National
Scenic Riverway to encourage it to be eligible for
consideration. There will be another call for proposals in
late 2021 or 2022 because FLAP is on a 3-year cycle.
National Parks Foundation
The National Parks Foundation is the official charitable
partner of the National Park Service. They work
to provide resources and support for parks and
programming.
Mississippi Park Connection
The nonprofit partner of the Mississippi National River
and Recreation Area is Mississippi Park Connection. It
may be a source of information on a potential canoe/
kayak rental kiosk.
Minnesota DNR
Conservation Partners Legacy (CPL) program through
the DNR provides funding for habitat restoration
projects.
DNR School Forests and Outdoor Classroom grants are
potential options for North Aiple Park; a school partner
would be needed to utilize the resources.
Other Funding Sources
The Middle St. Croix Watershed Management
Organization and the Washington County Soil and
Water Conservation District may have resources for
water quality and vegetation restoration projects on
the site.
Local and national outdoor recreation groups and
organizations may be sought out to partner on
implementation of recreation facilities.

Infrastructure and Utilities
Items that will need to be addressed in coordination with the Aiple residence renovation and may need further
study include: removal of oil tanks on the property; removal of buried transformer near the house; and transfer of
sanitary sewer to City sewer system.
Electrical connections maybe needed for the picnic shelter at the former garage site.
Water connections may be desired in the future at the south end of the site near the trail parking.

CONCEPTUAL SITE PLANNING (2016-2017)
During 2016 and 2017, the City worked with a consulting team to evaluate
existing site conditions, analyze potential opportunities, and develop
preliminary concepts. The products from that process are on the following

Having a launch for canoes, kayaks, and paddleboards is over-
whelmingly desired. People cite it as a missing amenity in Stillwa-
ter and the difficulties competing with motorized launches else-
where. Some want a put -in very close to parking, for ease of
launching, or a dedicated drop-off/pick-up parking zone. Others
desire rentals so that parking and additional impervious is not
necessary (and so the launch is accessible for those who do not
have their own crafts). New ideas include using the garage as a
cold storage space that could be rented by paddlers who want to
keep their craft onsite.
Generally, people love the peace and quiet of being in a park along
the river. There is good support for walking trails throughout the
park, with mixed reviews of whether the trails should be natural
surface (suggested for the State Trail Connection to discourage
biking into the park) or accessible paved. People are intrigued by
the grotto and trout pond and would like to explore those areas.
People overwhelmingly support places to picnic (tables and shel-
ters) and access to restrooms/drinking water. Generally, people like
the idea of biking to access the park (and want bike parking within
sight of amenities), but some are concerned about the park becom-
ing a throughway for cyclists and skateboarders. New ideas include
adding a seating area with firepit, including an informal (loose
parts) nature play area, and having amenities for dog owners.
There were many comments in favor of restoration of habitat
within the park, especially along the shoreline. Suggestions
include replacing lawn with no mow or pollinator lawns, using
native plants, removing invasives, avoiding unnatural lighting, and
using vegetative shoreline restoration rather than rip rap. In
general, people want to preserve the areas of natural beauty and
the peaceful, quiet access to nature along the river.

People frequently mention liking a beach when they mention
water and/or paddle access.
Parking was a contentious issue in the Social pinpoint, with
passionate respondents posting multiple times about it. Those in
favor thought it was essential to older visitors, those with disabili-
ties, and to paddle access. Others thought cars should not be
allowed in the park, adding impervious surface is irresponsible,
and there is parking available downtown.
People who mentioned the pier or fishing were very supportive of
it and labeled fishing access a high priority. Some suggested
having two fishing pier locations and another said one would be
enough. Having an accessible fishing pier with ADA trail is desired.

Among those who mentioned education, three deemed it the
park's highest priority. Some suggest reusing the building as an
educational center, while others want to see both indoor and
outdoor space available for hands-on education, including acces-
sible places to access the water and creative nature play areas for
schools, clubs, and the general public.
One respondent thought that the building was the highest priority,
but two others had doubts about the cost/potential success of
attempting to repurpose it. In general, people want places to picnic
and store/rent paddle craft, along with places to gather for educa-
tion, but they are open to those things being done in open shelters
or a new on -site facility.
