Flex Opportunity Area 07/28/2013 CUNINGHAM G R 0 U P Introduction This report documents the product of the feasibility study portion of the Cottageville Park expansion. As a background to this feasibility report, the master plan report produced a site design that encompassed the entire proposed park area. The framework of the proposed concept reflects programmatic and functional requirements set forth by the Minnehaha Creek Watershed District (MCWD), the City of Hopkins & its residents. Three additive levels of park design and implementation based on funding were identified in the final park master plan. The basic framework and contractual stormwater obligations were satisfied in the $2.4 million `Basic Park'. A step up from the basic park added in amenities such as a green roof pavilion and exterior gathering spaces for the $3.3 Million `Signature Park'. The $5.2 Million `Awesome Park' encompasses a full build -out of the park. Following the master plan, Cuningham Group, along with WSB Engineers, were tasked to complete a feasibility report, the ultimate goal of which is to prioritize elements from the master plan into a project which can realized in a series of phases. This road map lays out the timing and expectations of future phases of park construction within the realities of funding, adjacent developments and future opportunities. The remainder of this report outlines the overall phasing plan, proposed improvements for a Phase 1 project, and provides information and budgets for subsequent phases and outlines an overall construction and funding schedule. 07/28/2013 MULTI- FAMILY RESIDENTIAL EMILY TIAL 07/28/2013 Overall Phasing Diagram The overall phasing diagram gives a snapshot of the major park components labeled and numbered or dated to show construction phase or timeline, respectively. The diagram also clearly shows the amount of activity surrounding this project. The north, south and west sides of this park expansion will have major design and construction activities in the next 3 to 4 years. One objective of this feasibility report is to quantify and capitalize on those improvements by coordinating park construction and funding timelines. The advantage of this approach is designing and building park elements to fit with adjacent improvements and vice -versa. Since the beginning of this feasibility process, a number of updates have influenced the sequence of construction and phasing. 2 3 4 The northwest corner of the park highlighted in red contains the unpurchased structure and illustrates the driveway easement that cut off proposed improvements @ the northwest corner of the park. This portion of the project contained an entry, pavilion, 2-5 play area and a portion of the westernmost stormwater pond. After receipt of the soil boring report, the proposed stormwater requirement of treating 11.2 lbs of dissolved phosphorus will be more easily satisfied than previously thought. This reduces the amount of previously planned infrastructure (cost) required to meet the goals outlined in the agreement between Hopkins & MCWD. There is additional potential of being able to increase the amount of treatment above the goals previously outlined. The Lake Street re -build is planned for 2015. The improvements proposed within the Lake Street right of way will be rolled into the project costs of the street improvements. Blake Road (County Road 20) is tentatively proposed to be re -built in 2017, with preliminary design kicking off in the fall of 2013. Similar to Lake Street, the proposed 07/28/2013 improvements within the Blake Road right of way will be rolled into the project costs of the street improvements. 5. Fencing is currently being constructed along the single family residential property to the east of the park. 6. The community garden to stay in place for this year's growing season. Detailed design will take into account the timing of the harvest and the proposed grading within the park. 7. PPL (Project for Pride in Living) is proposing to build affordable, multi -family housing to the north of the park, across the existing alley. The design and construction timeline of this project not only provides an opportunity for shared funding sources and coordinated construction activities, but more importantly, an opportunity to strengthen the relationship between the park and the surrounding neighborhood. 8. The `Flex' area was previously called out as a location for an entrance monument. Upon further review, this area may have educational/entrepreneurial activities that relate to the park. Further development will help to flesh out the ultimate realization of this space. 9. Funds available for design and construction of a Phase 1 project have been estimated and inform the proposed Phase 1 project. 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 Ii ■ 1� PPL (MULTI -FAMILY)- 2015 ALLEY- 2 2-5 PLA 1 PAVILION- 3 DUPLEX , I P GARDEN -1 5-12 PLAY- 1 &2 KNOLL- 2' BIO -FILTRATION -1 OPEN PLAY -1 %I rPND- WALKS-2 PPL (MULTI -FAMILY) 2016 B BA L L-2 r� SINGLE FAMILY RESIDENTIAL — J 10 to ,,i CREEK EDGE -1 4 1 _. 40 os 10 ` 40FI CREEK ENTRY -2 I *$ 5 , o s \v CREEKCREEK R��v , EDGE -1 ACCESS -1 ES���� v I� FLEX - �� '10 00 � SINGLE FAMILY I RESIDENTIAL I,40to 10 '.

The proposed Phase 1 (broken down into Phases 1A & 1 B) elements are shown in blocked color and labeled on the diagram to the right. Construction of Phase 1 is proposed to start late fall of 2013 and continue through the summer of 2014. Phase 1A (starting late fall of 2013) will focus on demolition of existing site elements, overall site grading, and construction of elements related to storm water treatment. General site grading is proposed to start in the late fall to take advantage of lower creek and groundwater levels. The overall grading plan for the park will be designed to encompass all of the acquired park portions and also to allow for future adjacent improvements. We are anticipating approximately 5,000 cubic yards of excavation for storm water and creek features. It is anticipated that park features, amenities, and topography will consume much of this material, requiring little material to be hauled off-site. Based on the geotechnical analysis, the majority of the subsurface soils appear to be appropriate for general site grading. Phase 1B (starting spring of 2014) builds out and finishes the elements graded in Phase 1A. The focus will be on the construction of intra -park connections, seating, play elements and planting. Clarification of elements included in Phase 113 - Creek B:Creek Edge- The creek edge at the SW corner of the site is to be eased and cleared in order to create a long view into the park. The excess cut material will be re -used in the park to create features. The easing also makes accessible paths down to the water's edge possible. • BBALL- The existing basketball court will be kept in place. • Walks- Concrete walks will serve as the web that links and defines the spaces. Accessibility will be critical to ensuring that this park can serve people of all needs. • Knoll- The knoll is a slightly elevated platform that will be a combination of paved and unpaved elements. The knoll will serve as the unofficial group meeting space until the pavilion is included in a future phase. • Garden- The proposed community garden will replace the current garden on site. The size will be approximately 30% larger than 07/28/2013 the current location and encompassed by an ornamental fence. This is primarily a community engagement/teaching garden. There is currently a proposal to include a separate water supply to the community garden that will relate to the future 2-5 play area and be part of the water education component of the park • Entry- Entries at the corner of the parks will be paved highlight areas that are designed to welcome and engage the park users • 5-12 Play- There is a strong desire to include a play element in the first phase of this project. What will be designed will be able to adapt to future phases when funds become available for a full build -out of the 5-12 play area. • Open Play- The open play area is an open, flexible turf grass space that serves as the hub around which all of the park elements connect. • Creek Crossing- The final design of the creek crossing will allow both canoes and pedestrians to navigate and cross the creek, respectively. This crossing will also included a launch and landing area that is accessible. • Flex- The re -named flex space will continue to be investigated in order to maximize its location and future integration to the park. • Pond- The eastern pond is the workhorse that removes dissolved phosphorus from storm water. This pond will be graded and seeded with native plants to ensure it's function. • Bio -filtration- The bio -filtration area collects storm water from the pipes running down Blake Road, acting as the first line of treatment. • Storm water Education Loop- Interpretive graphics, signage and mapping relates the story of storm water and the creek, reinforcing the educational component of Cottageville Park. Elements not included in the Phase 1 project are described in the subsequent Phase diagrams. In the interim, those areas will be graded and seeded for stability.
