SWMP January II, 2001 Page 3 ^ discusses implementation strategies: o Water quantity management system • the system of storm sewers, ditches, swales, emergency overflows and ponds to collect store and convey surface water, o Water quallt)* management system - aholistic approach that requires water quality monitoring, public education and involvement, and strategies for determining appropriate management alternatives for various development conditions as well as a system of water quality ponds. A wide range of activities is suggested, noting that wnter quality management requires community cooperation. Note that hardcover management is only a very minor component of this plan... we will be conferring with the people at Boncstroo as to how a discussion of our hardcover standards can be added to the Plan text. o A cost estimate for completing the system is provided, iiKtuding a 5-year Capital Improvement Plan (CIP) totaling approximately $2 million (sec pages 7-20 thru 7- 25). Total long term cost of the system is expected to be around $1 1 million, o Methods for financing construction of the system are discussed, summarized as follows: AcilYiix Svatem Finaueing Method New Development 1) Developer construction of system or components; and or 2) Trunk Fee on a per-acre basis for regional system impacts, adjusted for land use type Expansion of Existing Structure Partial Trunk Fee based on impacts and site ability to obtain 60% nutrient removal Developed Areas 1) Direct assessment of contributing benefitting properties 2) Stomiwater Utility Fee - an annual fee charged to all based on the amount of stormwater runoff generated by the property A numberof grant programs for surface water management activities or system construction are also identified. Chapter 8 includes a summary and rccommendatioDS for the Council's consideration. Appendices A thru I conuiin the data for each drainage area, proposed system parameters and cost estimates, wetland data, and a complete Surface Water System map. (The appendices are rather voluminous and have not been copi^ in their entirety for you, but can be made available if you want to review a specific drainage area). Aside from a few paragraphs that staff proposes be added (primarily in the inlroduclory sections) to more clearly establish Orono’s historic philosophy on stormwater management as related to the protection of Lake Minnetonka, the Plan is complete.
