<br />City of Centerville SWMP Review <br />12/JO/OJ <br />Pogel <br /> <br />6.5 - Include text on identifying retrofit opportunities in the City for water quality and stormwater rate control. <br />Include in the Plan a figure identifying the existing water quality treatment with regard to NURP standards for <br />7 each subwatershed, attached is an example from the City of New Brighton. This figure will allow for <br />identification of water quality treatment ponds and subwatersheds that will benefit from retrofitting or regional <br />water quality ponding. Identify locations of non-treated discharges to City Lakes and Creeks for future retrofit <br />opportunities. The Implementation Plan and OP have already done a good job of identifying retrofit <br />opportunities for some of these areas. <br /> <br />8.0 - The OPs identify using Stormceptor Manholes as a retrofit to improve water quality. Please provide the <br />RCWD with new literature documenting the performance of this type of practice (not by the manufacturer) in a <br />8 field setting. It is our opinion that the cost of these practices far outweighs the water quality benefits provided. <br />The District prefers small scale BMFs such as rainwater gardens, infiltration practices, and vegetated swales to <br />improve water quality. Please consider including these types of BMPs in place of or in addition to the <br />Stormceptor Manholes. <br /> <br />9. A timeIine should accompany the proposed OPs. <br /> <br />Appendices <br />1 0.. PleaSe include the RCWD's full permit application, brochure materials, infdtration checklist, and design <br />guidelines in the Plan's appendices. . <br /> <br />The City of Centerville has presented a well written Plan with specific implementation strategies and ClPs to <br />11 address their goals and objectives. The RCWD looks forward to the completion of the CenlervilIe Surface Water <br />Management Plan and the start of their implementation program. <br /> <br />12 Please feel free to contact me (651.770.8448) with any questions or if you wish to schedule a meeting to discuss <br />the above conunenls. <br /> <br />Sincerely, <br /> <br /><. <br /> <br />~.~ <br /> <br />Jennifer Olson <br />Emmons & Olivier Resources <br /> <br />cc: RCWD Office <br />Kim Moore-Sykes, Centerville Administrator <br />Brett Emmons, EOR, RCWD Engineer <br />Helen Boyer.
