York Commons Park
In February's subcommittee meeting, the City expressed its desire to focus on the potential use of York Commons as it impacts the greatest number of homes. In addition, it stated that Burke was still looking at the concept of underground water storage in the York Commons parking lot as a possible alternative. The City shared that Burke had now calculated the following concerning the potential utilization of the parking lot in lieu of constructing the front detention lobe as shown in the conceptual plans:
Underground Open Concrete Storage Vault
Volume: 5 acre feet
Cost: $2.9 million
Permeable Pavers with Stone Base
Volume: 2 acre feet
Cost: $3.2 million
The proposed plan for the City/Burke called for a total provision of 26 acre feet of storage to be achieved through the east lobe (in the back of the park providing 19 acre ft) and the west lobe (in front of the park) providing 7 acre feet. In addition Burke provided the following general cost estimates for the construction of stormwater management facilities:
Above ground: $100,000/acre ft
Underground concrete vault: $500,000/acre ft
Permeable paver systems $1,600,000/acre ft
East End Park
At February's subcommittee meeting, we asked that the City look at the possibility of excavating the center section of East End Park, thus eliminating or reducing the need to excavate the western portion of the park. We also inquired about the concept of lessening the severity of the slope walls at East End and incorporating amphitheatre style seating. At this point, the City was still working on getting engineering and cost details concerning the $12 million cost for piping from East End to Golden Meadows.
At this meeting, the City reported that the center section of the park would need to be lowered approximately 10 ft at an additional cost of $800,000 in order to provide the necessary volume and that this would result in an 11-ft embankment needing to be constructed just west of the tennis courts. They also indicated that lessening the severity of the slope walls in the western portion of the park could be achieved, but it was agreed by all that impacts to the layout of the ball fields would need to be considered in the design process. We then asked about the potential acquisition of homes on Geneva in order to provide overland flow rather than installing and using storm pipes below grade. The City indicated that they will have Burke look into the idea. Finally the City has yet to provide details conerning the $12 million cost for piping from East End to Golden Meadows.
