In this letter you request consideration of alternate locations for water quality Pond FL- QI5 proposed for the shoreline area of Forest Lake. The City of Orono is in the process of developing a Storm Water Management Plan to evaluate various methods of reducing flooding problems and improving the water quality of the lakes and wetlands within the City. This plan includes conceptual locations for storm water ponds and other storm sewer system improvements. One goal of this plan is to complete conceptual designs for storm sewer systems to reduce flooding and improve water quality. The basic concept for the design and location of water quality ponds is to locate them as close as possible to lakes and wetlands to capture and treat the maximum amount of water before it enters the lake or wetland. As ponds are located further from the lake or wetland, the amount of flow captured is reduced and improvements to water quality are reduced. This basic design and location concept is followed throughout the plan. This plan presents conceptual designs in conformance with the plan goals. The designs shown are conceptual in nature based on topographic mapping derived from aerial photography. Before any projects are approved and constructed, feasibility studies and plans and specifications will need to be completed. Telephone (612) 473-7357 • FAX 473-0510
