Located on the western shoreline of the scenic St. Croix River, Bridgeview Park off ers a unique opportunity to experience nature while the urban amenities and charm of Downtown Stillwater. In the recent past, the park property has been variously referred to as the “Aiple Property” and the “Barge Terminal Property.” The City of Stillwater last prepared a master plan for the “Aiple Property” in 1998, which also included planning for Kolliner Park located across the river. A number of factors
led the City to embark upon an update to the previous plan including anticipated mitigation projects from the Minnesota Department of Transportation’s (MnDOT) St. Croix Crossing project and community interest in improving recreational boating access. The property also has numerous historical resources from the 19th century industrial uses that could enrich the experience of the park through interpretive exhibits.

Regulatory Context
As part of the legislation designating the St. Croix as a National Wild and Scenic River, the Cooperative Management Plan (2002) was developed to guide stewardship of the river and its surroundings. Geographically, the overall plan addresses the river extents from Taylors Falls extending south to Prescott where it converges with the Mississippi River. Stillwater sits within the section of the river designated as an “active social recreation area.” It is also designated as a “State Zone,” which is managed cooperatively by the Minnesota Department of Natural Resources (MnDNR) and the Wisconsin Department of Natural Resources (WiDNR).
North of Stillwater, the river transitions into a “moderate recreation” area and then a “quiet waters” area, which is managed by the National Park Service. See Figure 4 for an overview map of the Riverway. In addition, other federal, state, and local agencies have jurisdiction and permitting authority. See Figure 6 for a comprehensive matrix outlining regulatory responsibilities.

1998 Master Plan Highlights
The original Aiple Property Master Plan (1998) incorporated extensive public input through open houses and survey questionnaires. While that process occurred sixteen years ago, many of the same issues and sentiments are still relevant. A major component of the plan which is no longer possible was the potential to renovate and re-use the Terra Terminal industrial building on site, formerly used to store fertilizer, as a public Visitor Center. That building, formerly located at the north end of the park property, was removed as part of mitigation for the St. Croix Crossing Project. In summary, the following lists highlight the public’s sentiment about the park at the time, which eventually lead to a preferred plan that was adopted by the City Council.
Frequently Mentioned Issues and Concerns:
• Preservation of views/landscape
• Environmental issues
• Preservation of heritage
Preferred Uses:
• Walking connection to Downtown
• Hiking trails
• Native plantings/wildfl owers
• Picnic shelter
• Biking trails

Public Involvement
Initiated in the summer of 2014, the master plan update unfolded over an approximately six month period. The City and its consultant team coordinated with numerous agencies, commissions, the local business community, and the public to refresh the previous plan according to the current circumstances and the City’s related downtown planning eff orts. Through the public involvement process, a list of primary goals emerged that should guide future development of the park property over time.
Primary Master Plan Goals:
• Improve convenient access to the park by car, boat, bike, and on foot.
• Capitalize on the park’s proximity to downtown to welcome park visitors to the greater Stillwater community.
• Respect the scenic character of the river.
• Re-envision opportunities for the site’s historical resources to become more accessible and engaging.
• Extend active recreation opportunities through trail linkages.
• Provide fl exible spaces for public gathering and potential park programming.

Related Planning and Design
It is a dynamic period of planning and design for Downtown Stillwater and the St. Croix River vicinity. The implementation of the St. Croix Crossing project has reach beyond the primary river crossing bridge and highway design that includes a number of mitigation measures that have relevance for the future development of Bridgeview Park as outlined in the list at right. In addition, the City has been developing plans for several years in conjunction with MnDNR for a potential public boat launch in the park. Lastly, the Greater Stillwater Chamber of Commerce and local business community has initiated a downtown revitalization eff ort that seeks to identify opportunities that will make the downtown commercial district a vibrant destination for residents and visitors in addition to growing the economic base of the community.
St. Croix Crossing Mitigation Measures:
• Removal of the Terra Terminal building
• Kolliner Park: removal of non-historic elements to allow reversion to a “natural state”
• Riverway interpretation
• Public boat access study
• Completion of the loop trail system including grading of the municipal barge facility property
• Recreation, education, and Riverway restoration
• Lift Bridge pedestrian/bicycle conversion
• Historic resources study and stabilization
• Relocation of historic Bergstein buildings to site

Existing Site Conditions2. Site Characteristics
Located south of Downtown Stillwater, the Bridgeview Park property is approximately 20 acres in size – approximately 3600 ft. (north to south) by 250 feet (east to west). In some locations, it is as narrow as approximately 125 feet. The northern edge of the property, near the St. Croix Boat & Packet business, is approximately ¼ mile from the Lift Bridge at the terminus of Chestnut Street. The southern edge of the property is approximately one mile from the Lift Bridge.
Situated at a bend in the river, the site has expansive views of the river valley upstream and downstream where vegetation is thinned along the shoreline. The St. Croix Boat & Packet dock and Lift Bridge in the distance are prominent visual features looking north. Sunnyside Marina is located south of the site, and the new main river bridge will be visible in the distance also. The location will aff ord a unique opportunity to observe the two bridges from a single vantage point amidst the lush foliage of the surrounding bluff s.

Natural Resources Context
The Bridgeview Park property is a thin strip of deciduous fl oodplain forest at the base of tall limestone bluff s immediately west of St. Croix Trail (TH 95/TH 36). The terrain in the park is steep and varied in many locations, primarily along the park’s western edge where it abuts St. Croix Trail. The highway and old railroad alignment were constructed on man-made “benches” within this rugged terrain. Groundwater is often seen seeping through the rock face and a number of historic limestone and concrete walls dating from the site’s sawmill period still retain grade.
The site elevation ranges from approximately 733 (above sea level) at the south end near the highway to 676 along the shoreline (according to recent aerial photography). The 100 Year Floodplain elevation according to current FEMA fl ood insurance mapping is approximately 693. It is common for portions of the site to experience seasonal fl ooding. The natural terrain is a signifi cant visual feature and future park development should take care to minimize and mitigate potential impacts.
Floodplain tree species present in this area include black willow, silver maple, box elder, and eastern cottonwood. Vegetation on the site has been disturbed signifi cantly
by past land use. Currently, dense tree stands and undergrowth line the western edge of the site clinging to steep slopes. Vegetation along the shoreline is also fairly dense except in the center of the site where the shoreline was recently engineered and stabilized for the relocation of the historic Bergstein buildings. Future park improvements could include restoration and interpretation of fl oodplain forest and meadow areas to enrich the public’s understanding of the site’s inherent ecology.
Wildlife in the vicinity includes species on land, in the air, and in the water. Protected bird species nearby that were identifi ed in the St. Croix Crossing Project area include Swallows, Ospreys, Peregrine Falcons, and Bald Eagles. Mussel populations and fi sheries exist within the St. Croix River. The St. Croix Crossing Project identifi ed a number of threatened and endangered mussel species in the project area. Mussel habitat tends to be best in the shallow “wave wash” zone near the river bank. If the City elects to proceed with development of a new transient dock, detailed exploration of the river bottom will be important to avoid any potential habitat impacts and also provid a basis for the design of dock anchorages.

Cultural Resources Context
The Bridgeview Park property is rich with 19th century Stillwater history. It is set within the recently recognized South Main Archaeological District on the National Register of Historic Places (NHRP). One hundred and fi fty years ago, it was not a place to recreate – it was a place of industry. The area was home to a huge sawmill complex known as the Northwestern Mill, operated by the Hersey, Bean, and Brown Company. Archaeological study conducted for the St. Croix Crossing Project refers to this as the Hersey-Bean Sawmill. The mill was built in 1853 and by 1881 it employed 225 men and could produce 18 million board feet of lumber a year. Rising production
costs, diminishing supplies of timber and increased distances to markets contributed to the mill’s closure in 1904. By 1910, nearly all of the structures associated with the operation had been dismantled, however a few stone and brick foundations can still be found on the park property. These “ruins” off er an opportunity to provide a window on a unique aspect of Stillwater’s past through development of a coordinated interpretive plan along the proposed trails in the park. Additionally, the park is included within the Stillwater Cultural Landscape District and a gateway to the Stillwater Commercial

Existing Site Conditions
MnDOT is in the process of reconstructing St. Croix Trail (TH 95/TH 36) adjacent the southern portion of the site and the south access drive to the park which will be shared with Sunnyside Marina. The site is currently accessed from the north via a bituminous drive extending from the municipal parking lot which eventually changes to a gravel road within the park property. The existing drive is narrow and often congested with parked cars along the shoreline. MnDOT’s Loop Trail Project will construct trails through the park that extend from the new main river bridge through the tight downtown approach area north of the park property to Nelson St and Lowell Park.
The railroad route through the site parallels St. Croix Trail on the east side. Moving from south to north, the railroad grade becomes further below the elevation of
the highway – separated by steep slope. MnDOT will construct a pedestrian/bicycle trail along the old rail alignment as part of the Loop Trail Project. The rails of the former railroad line are still in place, but will be removed as part of the trail construction.
Several businesses are clustered near the north end of the property including St. Croix Boat & Packet, which operates tour boats, the Dock Café, the Brick Alley restaurant, and a handful of other tenants in the buildings near the municipal parking lot. The Oasis Café is located across St. Croix Trail approximately mid-way along the length of the site. St. Croix Boat & Packet provides transient dock slips to the public for a fee adjacent to the larger riverboat docking areas. The municipal lot charges fees for parking.

Potential Activity Programming and Partnerships3. Master Plan
By virtue of its scenic location and proximity to downtown, Bridgeview Park has the potential to off er a diverse array of recreational experiences. To make the park attractive and truly accessible to the public, the design should consider a broad cross section of potential users and anticipate how they might interact. Bicyclists, walkers, boaters, anglers, artists, and others will have both common and unique needs. Out of town visitors and residents will have greatly diff erent perspectives.
Additionally, seasonal conditions such as fl ooding in low areas or trails cleared of snow will heavily infl uence the park’s use year round. All design features will be required to meet Americans with Disabilities Act (ADA) requirements. Lastly, a commitment to ongoing maintenance and upkeep of physical investments will ensure that park visitors perceive a high level of care creating a quality overall experience.
Figure 26 Recreational Trails
B R I D G E V I E W P A R K3 - 2
Site Program and Design
The overall plan responds to the site’s existing features and the trail system. It is likely that the park will serve as a primary trailhead and orientation point for the St. Croix Crossing Loop Trail. At the same time, the park will be a destination in and of itself with primary features spread out along its length. By clustering related activities within diff erent zones of the park, pressure between diff erent user groups will be minimized.The southern zone’s primary focus is boating access with supporting parking areas. A fi shing pier would complement the boat launch and a small clearing alongside the lower loop trail provides an informal picnic area.The central zone is only accessible by bicycle or on foot, and on most days would be geared towards passive recreation such as nature or history walks or informal picnicking. On special occasions, the picnic shelter could be reserved for larger groups or host performances, and the lawn could be converted to audience seating. The northern zone is where the highest level of activity is anticipated. Clearly designated circulation forms the backbone of this area including a one-way access drive (southbound), parking, bicycle trail, and pedestrian promenade along the shoreline. The historic Bergstein buildings could serve as a focal point for the park, pending a separate study commissioned by the City on the re-use and rehabilitation of the structures. This is also a logical trailhead where the upper and lower loop trails come together and people would arrive from downtown.Adjacent to the historic buildings, the proposed transient dock would hug the shoreline and would be designed to move up and down with changing water levels with a fl exible pedestrian ramp system. The linear layout permits boats of diff erent sizes to tie up and has a capacity of approximately 10 to 16 vessels. The dock could potentially be expanded by lengthening it or adding “fi ngers” to increase the capacity if needed. An optional concept for a dock at Kolliner Park could also be considered in conjunction with a reassessment of the park as a whole.

Transient Dock Study
Recreational boating is a popular local activity and viewed by the Stillwater business community as a fundamental part of the economy, but with unrealized growth potential. A Dock Needs Analysis report (see Appendix B) was prepared that delved into the characteristics of recreational boating on the St. Croix River, investigated marina usage, and identifi ed potential locations for a new dock. For the study, “transient docking” was defi ned to be short-term daily use only - not overnight. In addition, any potential new dock would need to be designed with limited services so as not to be technically classifi ed as a “marina” since current regulations in the Cooperative Management Plan (2002) prohibit the development of any new marinas within the Riverway.
Studies in the late 1990’s estimated that approximately 310,000 people recreated on the river annually out of a total of over 2 million visitors. Riverway usage at Stillwater was calibrated at 16 acres per moving boat. In contrast, the Hudson Narrows area saw a density of 2.2 acres per moving boat. Based on review of current aerial mapping, there are approximately 2,000 boat slips overall available between Stillwater and Prescott. At a glance, the marinas appear nearly full during the boating season, which was generally confi rmed by a survey of marina managers. While many of these facilities try to accommodate transient boaters as space allows, very few slips are actually dedicated for public use.

Transient Dock Study
Based on the assessment of current recreational boating use on the Lower St. Croix, Stillwater is currently not conveniently connected to the boating activity already occurring in close proximity and potentially missing out on the economic benefi ts and additional vitality that recreational boating would bring. Based on the evaluation of key factors, the recommended location for the new dock is the stretch of shoreline between Nelson Street and the Bergstein Buildings (location #3 on the map on the following page). One specifi c location option, within this stretch of shoreline, is directly adjacent to the Bergstein Buildings, as shown in Figures 27, 30 and 41. Other potential options are provided in Appendix C.
Primary Benefi ts of the Selected Dock Location:
• Located south of the Lift Bridge and conveniently accessible by avoiding bridge opening restrictions.
• Set within a ½ mile walking radius to the center of downtown (Chestnut Street) - a reasonable 5 to 10 minute walk for most people.
• Already generally clear of woody vegetation along the shoreline and engineered for stability near the Bergstein Buildings.
• Away from the Hersey-Bean Sawmill historical features, which are generally congregated in the middle and southern ends of the property.
• Potential to develop the dock in conjunction with the new park.
• Opportunity to utilize space within the recently relocated Bergstein buildings for management and maintenance of the dock without the need for a new structure (pending a separate study by the City).

Potential Activity Programming and Partnerships
In addition to the proposed physical improvements, programmed activities will enliven the park and enhance the feeling of safety for all users. Activities could be initiated by the City Parks Department, schools, or partnerships with nature, arts, and athletic organizations. Potential activities might include the following:
• Nature walks
• History walks
• School fi eld trips
• Concerts
• Theater performances
• Community celebrations
• Fishing or boating lessons
• Group walk or run events
There is also potential for the City to create partnerships with private vendors to operate within the park. Such arrangements would provide new economic opportunities for the private sector while minimizing the need for additional City management. Potential partnerships might include:
• Management of the transient dock
• Recreational rentals (bikes, non-motorized watercraft, etc.)
• Food and beverages (food trucks or other temporary facilities)
• Private events (weddings, corporate gatherings, etc.)

4. Implementation
The Master Plan is intended to highlight the City’s overall long-term vision for the park and outline a potential path to implementation. There is no pre-determined timeline for full build-out of the plan. Plan implementation will be determined at the City Council’s discretion and in coordination with partnering agencies. The plan will be implemented in phases based on funding availability with the initial phase of trail construction, funded by MnDOT, to be constructed in 2016. Funding for future phases may include participation from other agencies, City funds, grants, or private donations. Phases may be implemented in varying order, but in a clustered fashion to avoid re-disturbing areas.
Primary Master Plan Phases:
• Phase 1 – Loop Trail, Stormwater Treatment Pond
• Phase 2 – Bergstein Building Rehabilitation, North Access Drive, Parking, Trailhead
• Phase 3 – Transient Boat Dock, South Access Drive
• Phase 4 – Boat Launch, Parking, Trailhead
• Phase 5 – Picnic Areas, Central Lawn, Historical and Ecological Discovery Area
Note:City-owned parcels are highlighted in red.

Subject: Stillwater Dock Needs’ Analysis
Introduction and Context
Stillwater is a City rich with history set within a landscape of natural beauty, the Lower St. Croix National Scenic Riverway. Recreational boating is a popular local activity and viewed by the Stillwater business community as a fundamental part of the economy, but with unrealized growth potential. In general, tourism fuels Downtown Stillwater’s shops and eateries, but there is sentiment that boaters are spending their money elsewhere because of a shortage of convenient transient dock slips convenient. In one marina operator’s opinion, “There is a need for boaters to tie up somewhere so they can go downtown to eat and shop. Currently this is difficult if not impossible.” In order to respond to the business community’s sentiment, the City of Stillwater directed SRF to investigate the need for new transient docking and assess potentially suitable locations. For the purposes of the study, “transient docking” is defined to be short term daily use only - not overnight. In addition, any potential new dock would be designed with limited services so as not to be technically classified as a “marina” since current regulations in the Cooperative Management Plan (2002) restrict the development of any new marinas within the Riverway. Minnesota 2013 statute 86A.20 and Chapter 30 of the updated Wisconsin 2011-12 statutes provide guidance on definitions of different types of boating facilities. The study summarizes current inventory and demand for boating facilities in the designated “active recreation area” of the Lower St. Croix extending from Stillwater south to Prescott. The scope of the study does not include a detailed economic benefit analysis, although it may be eventually justified if plans for a dock progress beyond the master planning phase. Geographically, the focus area of the study to identify suitable locations included the Downtown shoreline, the Barge Terminal property (located immediately south of the St. Croix Boat and Packet riverboat docks), and Kolliner Park (located directly across the river from Downtown, in Wisconsin). Through review of aerial photography, an on-line survey, and conversations with the local community, a “picture” of current recreational boating and its relationship to Downtown Stillwater was discerned. It reveals that recreational boating on the river in the vicinity of Stillwater is highly popular but convenient access to Downtown or nearby parks is lacking.

Stillwater is not alone in addressing the challenge of accommodating recreational boaters. Extending to the confluence with the Mississippi River, five primary cities currently have sizable boating facilities – Stillwater, Bayport, Hudson, Afton and Prescott. They share an identity as “river towns,” contributing to the attraction of the region as a recreational destination. Historically, industrial uses predominated, but for the most part, the working riverfront has been transformed into recreational and residential uses. The multitude of marinas, parks, and trail systems that are existing or under development are an indication of its popularity and significance. Nevertheless, in order to benefit from recreational boating, communities must find the right balance between recreational use and the preservation and management of the significant natural and cultural resources that exist.
Recreational Water Use Overview
As part of the legislation designating the St. Croix as a National Wild and Scenic River, the Cooperative Management Plan (2002) was developed to guide stewardship of the river and its surroundings. Geographically, the overall plan addresses the river extents from Taylors Falls extending south to Prescott where it converges with the Mississippi River. Stillwater sits within the section of the river designated as an “active social recreation area,” which is managed primarily by Minnesota and Wisconsin. North of Stillwater, the river transitions into a “moderate recreation” area and then a “quiet waters” area, which is managed by the National Park Service. See Figure 1 for an overview map of the Riverway. In general, the management plan acknowledges the cultural and economic importance of recreational boating, but to ensure that the resource remains attractive and vital over time, it sets rules and standards limiting the usage. The primary measure for the establishing the carrying capacity of the river is boating density (acreage of water per moving boat). The threshold for more stringent regulations is 10 acres per moving boat. In 1997, as part of the Environmental Impact Statement (EIS) for the management plan, Riverway usage at Stillwater was calibrated at 16 acres per moving boat. In contrast, the Hudson Narrows area saw a density of 2.2 acres per moving boat. In addition to the level of usage, river hydrology and other natural characteristics factor into local regulations such as no-wake zones. Studies at the time the management plan was prepared estimated that approximately 310,000 people recreated on the river annually out of a total of over 2 million visitors. Assuming that most recreational boating traffic is seasonal (roughly six months out of the year), that equates to approximately 1,800 people per day (May through October), and presumably most would be weekend boaters. At one time, the designated Boundary Waters Commission performed regular bi-annual aerial surveys and created data on recreational boating usage, but the Commission is now disbanded and archived information is not currently accessible to the public. At the time it was drafted in order to prevent boating overuse, the plan stipulated that no new marinas or boat launches will be built with the exception of a proposed launch at A.S. King Generating Plant (currently operated by Xcel Energy). Consequently, any plans for new boating facilities would require close coordination with the managing and permitting agencies.

Boating Culture
The natural surroundings are undoubtedly an attraction for both motorized and non-motorized boaters. In addition, social factors also play a major role creating a boating culture that is inherent to the character of the Riverway and river towns. As noted above, there is a preponderance of private marinas in the area. While the study is limited to the suitability of a new transient dock – not a marina – certain lessons can be drawn from the marina setting that highlight boaters’ needs and expectations. Depending on size, a marina can actually develop the characteristics of a small village unto itself. In fact, some exclusive marinas are related directly to residential properties. Experientially, people enjoy seeing the variety of boats and social interactions that inevitably occur out on the dock. Access to restaurants, bars and shops is also a desirable aspect to marina location.
Boating is a lifestyle choice requiring significant time and monetary investment, and an entire support industry exists to supply and maintain people’s boats and facilities. Service providers fill the niche to allow people enjoy their boating experience without being burdened by all the upkeep. They also provide additional amenities that enhance the boating experience and general enjoyment of the Riverway including information, food and beverages, picnic areas, fishing gear, and restrooms to name just a few. Boating clubs and rental vendors, sometimes associated with marinas, also diversify access to the Riverway by providing watercraft to people who may not own one themselves.
Review of Existing Marinas and Docks
Along the Riverway, numerous private marinas provide a variety of boating facilities including: seasonal docking, transient docking, winter storage, repair and fueling. Some marinas are coupled with residential development, while others are purely commercial. In each city, there are typically several marinas, and scales vary widely from 12 slips up to 300. Based on review of current aerial mapping, there are approximately 2,000 boat slips overall available between Stillwater and Prescott. At a glance, the marinas appear nearly full, although it is impossible to determine exact usage and use fluctuates seasonally. Anecdotally, several marina operators indicated a gradual recovery in boating usage since a sharp drop-off in 2008/2009 coinciding with the national economic recession. See Figures 2 through 8 (attachments) for aerial photos showing marina and dock locations in each of the communities. It is notable how greatly the natural shoreline was altered to create protective areas for many of the marinas.
Through a survey of local marina managers, we learned that there are different uses of the term “transient docking” in the market as compared to the parameters specified by the City for the study. For most marinas, transient docking also includes overnight, weekly or stays of other longer temporary durations, and it is often a small part of a marina’s overall operation. In fact, some managers said that shorter duration transient docking is not profitable and would prefer to avoid it. We surmise that the challenge is primarily due to a marina’s ability to charge higher fees for overnight or extended usage according to the length of stay. For shorter stays though, it is common to charge hourly fees, similar to a street parking meter, which do not generate significant revenue in aggregate. In addition, boaters that stay longer may require additional services that generate supplemental income.
Bill Turnblad September 18, 2014 City of Stillwater Page 4
While many of these facilities try to accommodate transient boaters as space allows, very few slips are actually dedicated for public use. One particular site that is actually required to provide transient slips is the dock operated by St. Croix Boat and Packet for the paddle wheel excursion boats just south of Downtown Stillwater, by conditional use permit. At that dock, eighteen spaces are available to transient boaters. Community opinion on whether those spaces are utilized efficiently is mixed. Information logs on transient use provided by the owner indicate frequent transient use yet others have highlighted a lack of awareness of the slips since they are hard to see and are not advertised. Further coordination with the property owner may yield a better way to allow the dock to serve the public without hindering the paddle wheel business.
Additionally, the following table summarizes some key characteristics of each facility:

Non-motorized Boating Facilities
The Riverway is also a popular location for non-motorized watercraft including canoes, kayaks, rowers and sailboards. It is more difficult to ascertain the level of usage though. The Minnesota DNR lists six outfitters that rent canoes along the St Croix, including both Minnesota and Wisconsin businesses. For the most part, they are located in the vicinity of Taylors Falls and St. Croix Falls, north of Stillwater in the section of the river designated for “quiet waters.” The river channel in that section is narrower with many side channels and islands creating a backdrop for a different recreational experience that is presumably more popular for non-motorized watercraft than the immediate vicinity of Stillwater.
Nevertheless, provisions for non-motorized use should not necessarily be precluded near Stillwater and extending south in the “active social recreation area.” Discussions with local non-motorized users indicate a latent demand for access points and shoreline boat storage near Stillwater. Some features that would facilitate safe and convenient use at potential access points include gradual walking grades and docks that adjust to the current water level of the river. Additionally, enforcement of a no-wake zone near docks and boat launches would enable non-motorized users to share facilities with motorized users with fewer conflicts.
Potential Transient Dock Locations and Sizes
With the backdrop of the current characteristics of recreational boating and its regulatory framework established, the study team looked at Stillwater’s geography and initially identified five (5) potential locations for a new transient dock for further evaluation:
Downtown North (north of the Lift Bridge)
Downtown South (south of the Lift Bridge)
Barge Terminal North
Barge Terminal South
Kolliner Park (south of the Lift Bridge)
The following matrix (Table 2) illustrates a comparison of the suitability of the potential sites used to identify the preferred location. See Figure 9 for a map of the locations.

Generally, to minimize visual impact and align with the river current, a linear dock that follows the shoreline and permits docking on one side would be preferred. The capacity at each potential site would depend on the length of available shoreline, nearby obstacles, docking circulation, and flexibility to accommodate boats of different sizes. Linear docks in the locations studied would
Bill Turnblad September 18, 2014 City of Stillwater Page 9
accommodate between seven and 15 boats depending on boat sizes. Different configurations, with finger piers that branch off the main dock, would increase capacity up to 25 to 30 boats at the Barge Terminal and Kolliner Park sites but would be more challenging structurally and operationally. The length of walk for dock users is also a factor in layout dependent upon the number and location of ramp connections to the shoreline. Considering the overall usage of the riverway, it is anticipated that the range of sizes outlined would most likely fill up on a regular basis if accommodations were visible, convenient and at reasonable cost to boaters.
Conclusions
Based on our assessment of current recreational boating use on the Lower St. Croix, Stillwater is currently not conveniently connected to the boating activity already occurring in close proximity. Although it is the most populous of the “river towns”, Stillwater is potentially missing out on the potential economic benefits and additional vitality that recreational boating would bring to Downtown and the riverfront parks. If better operated and advertised, the transient slips already available at the existing St. Croix Boat and Packet dock have potential to alleviate some of the demand, but would likely not solve the issue entirely since they already see frequent use. Consequently, within the City’s parameters for a potential “transient dock” for daily use only, we conclude that a new dock would be warranted. Based on the evaluation of key factors as shown in Table 2 above, the recommended location for the new dock is the Barge Terminal North site. Although any new dock proposal would require stringent scrutiny for permitting, the Barge Terminal North site initially appears less controversial when compared to the locations immediately adjacent Downtown and Kolliner Park. In those locations, a dock would be in closer proximity to higher value cultural and natural resources and have a greater visual impact. At the other end of the spectrum, the Barge Terminal South site would be a much more distant walk to Downtown hindering convenient pedestrian access.
The Barge Terminal North site has a number of features that set it apart from the others:
Located south of the Lift Bridge and conveniently accessible by avoiding bridge opening restrictions.
Set within a ½ mile walking radius to the center of downtown (Chestnut Street) - a reasonable 5 to 10 minute walk for most people.
Already generally clear of woody vegetation along the shoreline and engineered for stability.
Away from the Hersey-Bean Sawmill historical features, which are generally congregated in the middle and southern ends of the property.
Potential to develop the dock in conjunction with the new park.
Opportunity to utilize space within the recently relocated Bergstein buildings for management and maintenance of the dock without the need for a new structure (pending a separate study by the City).
Bill Turnblad September 18, 2014 City of Stillwater Page 10
Nevertheless, the recommended Barge Terminal North site has challenges itself, primarily its close proximity to the historic Bergstein buildings and existing St. Croix Boat and Packet dock upstream. Ideally, the design of a new dock would minimize its visual impact on the shoreline regardless of location and complement the historic character of the City, requiring more detailed engineering and architectural study of pilings, shoreline connections, and palette of materials. With further study, the challenges at this location appear achievable though. If the City elects to pursue development of a new transient dock, continued engagement with partnering agencies and the public will be critical to establishing a feasible pathway to permitting and implementation.
