Specifications include, but are not limited to:Contract No. 1 – General Construction: The Urban Plains Park Pond Improvements are to be constructed within the parcels of 5050 30th Ave S, Fargo, ND 58104 and 5074 28th Ave S, Fargo, ND 58104. Work generally consists of the construction of a series of ponds and channels within the existing pond footprint between 28th Ave S and 32nd Ave S. Existing onsite aggregate will be salvaged and repurposed as channel and pond lining and edging. Ponding areas will have a PVC liner beneath the surface to maintain water levels. Channels will have a clay liner. The existing outlet control structure will be modified to lower the southernmost pond normal water level to provide adequate grade across the natural channel system. A lift station will be installed on the southern end of the site to provide recirculation within the system at a flow of 5 cfs. A biofilter diversion structure will be installed to allow flow during recirculation to bypass the biofilter media. The pond and channel system will incorporate trails, riprap, vegetation, meandering channels, ponding, and landscaping to provide aesthetically appealing, natural stream sections. A floating fountain will be installed within the southernmost pond for aesthetics and water quality benefits. This system allows the community the opportunity to experience a natural environment in and urban setting; something not typically possible.
