HomeMy WebLinkAbout030420-09.1ADMINISTRATIVE STAFF REPORT 9.1 TO: Mayor and Town Council March 4, 2020 SUBJECT: Resolution No. 16-2020, accepting the Updated Multi -Sport Skate Park Site Analysis and selecting a preferred location BACKGROUND At its October 15, 2019 meeting, the Town Council considered the updated site analysis for the Skate Park Feasibility Study, the results of an on-line community survey and written and oral comments provided by the community. The Town Council accepted the updated site analysis for the Skate Park Feasibility Study as presented and identified Diablo Vista, Osage Station and Sycamore Valley Parks as their top three preferred locations for a potential skate park site. Subsequently, Town staff was directed to work with Spohn Ranch Skate Parks (Consultant) to further evaluate these sites, including cost estimates, construction impacts and any other factors affecting feasibility. The consultant and staff have completed this additional evaluation and the results are prepared for review and discussion by the Town Council. Consideration and acceptance of the updated multi -sport skate park site analysis and selection of a preferred location would be the first step toward future construction of a multi -sport skate park in Danville. A determination to move forward with such a project would require the Town Council to add the project to the Capital Improvement Program. Such a decision would be dependent upon how a multi -sport skate park would be prioritized among all of the Town's current and future capital needs, and whether a potential funding source can be identified. DISCUSSION Feasibility Study Amendment - Design Report For the Study Amendment, the consultant reviewed and further analyzed locations within Diablo Vista, Osage Station and Sycamore Valley Parks to determine the viability for constructing and operating a multi -sport skate park. The following criteria was used by the consultant in determining the viability for constructing and operating a multi - sport skate park: • Size of space • Location within community • Visibility for observation and patrol ■ Impact on adjacent homes • Existing amenities and infrastructure ■ Environmental impact • Site conditions • Ease of development • ADA accessibility • Proximity to schools • Design suitability • Aspirational • Optimal location The Feasibility Study Amendment (Attachment B) provides conceptual schematic design concepts within each of the three park locations, Diablo Vista, Osage Station and Sycamore Valley. These concepts which include two options at Diablo Vista show a design of approximately 20,000 square feet to provide a better understanding of site impacts, structural implementation of a skatepark, cost estimates ranging from approximately $1.6 to $1.9 million and analysis of each design option. This Study Amendment also includes information regarding potential lighting which can be utilized at skate parks. The conceptual schematic designs shown in the attachment are not fully realized from a user perspective and are being presented to understand site impacts and integration. Staff Site Analysis Once the consultant completed the schematic designs, they were reviewed by the Town's engineering and maintenance staffs. While each of the proposed sites are feasible, each has some constraints and additional costs. These are summarized in Attachment C. The Town Council is being requested to review and consider approval of the Updated Multi -Sport Skate Park Site Analysis, along with identifying a preferred location for a potential multi -sport skate park. PUBLIC CONTACT Posting of the meeting agenda serves as notice to the general public. FISCAL IMPACT A future decision to move forward with design and construction of a multi -sport skate park would require including the project in the CIP and identifying one or more potential funding sources for the project. No project funding is currently included in the CIP.

The allotted area gives enough space to design and build a facility of optimal size. The design concept being presented shows several trees being removed, however if that proves undesirable, a slightly smaller design could also be accomplished: It would also be possible to leave the trees but relocate paths to achieve a larger size. The design shown has not been fully realized from a skate perspective and is being presented to better understand site impacts and integration. As the design is bordered by walkways, a combination of barriers and curbs would keep the skating activity and equipment within the intended space. The current barrier design isn't intended to be locked and offers access from all three converging pathways. A short pole (20') recessed lighting system is shown with photometric plan. A more complete low impact lighting plan could also make use of bollards distributed within the actual course areas. The drainage system is TBD, as we do not have a current soils report.

The Diablo Vista location has topographical design challenges. The ability to meet optimal course size will require grading, tree removal, and retaining walls that would add significant cost to the overall construction. Functionally this approach might still be limited and a less than optimal sized course achieved. The design shown shows fill being removed from the top of the hill and pushed down and supported by retaining walls. We've also allocated area on the opposite side of the existing pedestrian path to gain space and create a secondary bowl area. This is a similar concept as to the Sycamore Valley B design. Bisecting the skate areas is relatively unusual and in the case of Diablo Vista would essentially convert the pathway into skatepark and skatepark-specific access. We did not assume the ability to remove and make use of the existing water feature deck and pathway area(s). If that were possible, it would give the ability to change the layout plan and require less downhill construction. This location is difficult to patrol and observe activity. A security camera system might be desirable. This is not currently included in our pricing estimate. The access path including through the tot lot area would be the logical patrol route. The inclusion of bollards would help to control rider traffic on the pedestrian path, however this also limits the ability to patrol the area.

Design concept A (as shown in renderings) left intact the majority of the mosaic water sculpture area including the elevated mound and pedestrian path connection. It also left the existing rear pedestrian path connecting the ball fields and the tot lot play area. This was done to minimize impact on existing infrastructure and not remove or displace an existing park element. However, this approach to the design and construction comes with challenges and limitations. For the benefit of weighing the pros and cons we show an alternate "B" concept footprint (without skate design or rendering). This B concept encompasses the majority of the grass mound, the top circular concrete pad, the pedestrian path and pedestrian path connection. This would entail leveling a portion of the mound to shallow the topography. It would leave intact all of the tot lot play area, and a majority of the mosaic snake/dragon, landscaping and trough. This is just a spatial exercise and any exact line of delineation is very flexible. The immediate benefit of the alternate footprint is to make a consolidated space with more conducive grading for an integrated skate course. This would pull the park forward and be able to achieve the targeted park size without spilling down the rear slope. This would not only reduce the need for and cost of hillside construction but it would make the construction site more readily accessible and more construction -friendly. In the process it would also reduce sightline obstacles and and make the space easier to observe and patrol. Another goal is to eliminate the pedestrian thoroughfare though the tot lot. By creating a new access point to the side of the tot lot, this will draw potential wheeled traffic away from the area. We've also identified a fence line to establish a physical boundary. This will also help limit skatepark activities from bleeding out into the undeveloped park perimeter. We aren't showing this as gated or having a controlled access.

Calabrigo, Town Manager Rob Ewing, City Attorney Henry Perezalonso, Recreation, Arts & Community Services Director FROM: Tai J. Williams, Assistant Town Manager Steven Jones, City Engineer Dave Casteel, Maintenance Services Director RE: Multi -Sport Skate Park - Constructability and Cost Analysis Consistent with the direction provided by Town Council at its October 15, 2019 meeting, Town staff has worked with Spohn Ranch Skate Parks (Consultant) to further evaluate potential skate park sites at Diablo Vista, Osage Station and Sycamore Valley Parks. This subsequent evaluation is contained in the Consultant's Skate Park Feasibility Study Amendment dated December 17, 2019. This memorandum represents an in-house review of each potential park location identified in the Feasibility Study Amendment based on the Town staff's knowledge of each park site location, its infrastructure, and access constraints, as well as local area construction costs. DIABLO VISTA PARK This potential location could accommodate an approximate 24,334 square foot multi - sport skate park located on the knoll and south -facing slope adjacent to the existing children's play area and water feature. This area currently features a concrete pathway that loops around the backside of the children's play area, a passive turf area and picnic tables. It should be noted that the consultants design concept "did not assume the ability to remove and make use of the existing water feature deck and pathway area(s)". This is the area located above and to the south of the serpent water feature, i.e. the knoll. The consultant goes on to state that use of this area "would give the ability to change the layout plan and require less downhill construction." Staff believes that this would be the preferred approach to the development of this site and that should the location be selected, the existing use of the area would be changed to accommodate the skate park, rather than attempting to retain the existing features. 510 LA GONDA WAY, DANVILLE, CALIFORNIA 94526 Administration Building Engineering & Planning Transportation Maintenance Police Parks and Recreation (925)314-3388 (925)314-3330 (925)314-3310 (925)314-3310 (925)314-3450 (925)314-3700 (925)314-3400 ATTACHMENT C This location offers a number of advantages. It is proximate to the children s play area, the park restrooms and the main parking lot serving the park. Among the three options under consideration, it also provides the greatest level of separation from adjacent uses including existing homes, owing to its location within the park. This also means that from a security standpoint, the site is less visible, both within the park itself as well as from the surrounding public streets. Construction access to this location would be via the terminus of the main (eastern) parking lot, near the park restrooms. This site would require grading and retaining walls as well as the relocation of an existing water main. Site drainage can be connected to an existing storm drain system nearby. Construction activities would be minimally to moderately disruptive to other uses and activities occurring at the park. Taking into consideration additional design costs associated with engineering (grading and retaining walls), electrical systems, and bioretention areas, staff estimates the total project cost to be approximately $2.19 million. OSAGE STATION PARK This potential location could accommodate an approximate 25,344 square foot multi - sport park (exclusive of the immediately adjacent reconstructed pathways) located on a flat under-utilized triangular grass area immediately east of the Town's tennis courts and west of the hardcourt area at Charlotte Wood Middle School. Location -wise, the site is located adjacent to Charlotte Wood Middle School and the nearest homes are located approximately 250 feet to the south. Advantages offered by this location include proximity to park restrooms, site visibility and fairly close proximity to parking and drop off areas. Construction access to this location would be from the southern (Orange Blossom) parking lot at the park. Construction activities would be minimally to moderately disruptive to other uses and activities occurring at the park. As with Diablo Vista Park, this site requires relocation of a water main. This location also poses some drainage concerns. In its current condition, this is a flat site that is difficult to drain. This could be exacerbated by the excavation required in order to construct the skate park feature. As a result, staff believes that it would require the installation of a sump pump to ensure that the location is not susceptible to ponding. The installation and on-going maintenance costs associated with operating a sump pump is a significant unknown variable. Taking into consideration additional design costs associated with engineering, electrical systems, sump pump, bioretention areas and replacement of the surrounding pathways, staff estimates the total project cost to within an approximate range of $2.2-3.3 million. SYCAMORE VALLEY PARK This potential location could accommodate an approximate 20,665 square foot multi - sport park located between the smaller upper pond and picnic benches west of the bocce ball courts. Location -wise, the site is centrally located and some distance removed from adjacent uses that surround the park. The nearest homes are located approximately 400 feet to the south, on the south side of Camino Tassajara; school and church/ synagogue uses are located on the east and west sides of the park approximately 400 to 600 feet away. The site affords good visibility and reasonable proximity to park restrooms, parking and drop off areas. Similar to Diablo Vista Park, this location would require some grading and retaining walls. Construction access to this location would need to take place directly from Camino Tassajara, requiring the construction of a temporary gravel road across the south facing turf meadow, to the site. This access would require special traffic control measures. Construction activities would be moderately to significantly disruptive to other uses and activities occurring at the park. Taking into consideration additional design costs associated with engineering, electrical systems, bioretention areas, and higher construction related costs (temporary gravel road, traffic control, etc.), staff estimates the total project cost to be approximately $2.5 million.
