DISCUSSION /DIRECTION /ACTION — USE OF A PORTION OF THE WASTEWATER TREATMENT PLANT SITE FOR HIGHWAY 42 URBAN RENEWAL AREA CORE PROJECT AREA STORMWATER DETENTION/WATER QUALITY POND Mayor Muckle requested a staff presentation. Economic Development Director DeJong addressed the approach to stormwater detention for the Highway 42 Core Area. One option is to construct an offsite /regional stormwater detention /water quality pond on a portion of the City's existing wastewater treatment plant and use that detention pond to serve the Urban Renewal Area core area. The second alternative to an offsite /regional stormwater detention pond is to require property owners in the URA core area to use onsite detention. Background: The City is improving stormwater conveyance to reduce flooding impacts for the downtown area. The Highway 42 Revitalization Area has several developments coming together (DELO, Tebo Development and Boom Property). The Project: To provide required storm water detention and water quality off -site for developments in the Core Project Area. The opportunity would not exist without the City addressing downtown flooding constraints. The Project would have several City benefits: Better flood safety and mitigation; Cost would be more economical; would provide better public area in development; reduce future design challenges and at no financial costs to the City. Design considerations and tradeoffs: No guarantee offsite detention is feasible and land used for detention cannot be used for other purposes. Having regional detention off -site does not create the opportunity for greater density in the Core Area. The approved DELO Preliminary PUD limits overall density. Total estimated cost for off -site detention is $675,000. LRC proposes $350,000 be funded through Core Project Area Infrastructure Bonds. The remaining $325,000 funded from other LRC funds or from Core Area property owners. The maintenance costs will be paid by development. COUNCIL COMMENTS
