Interim Storm Water Ordinance August 6, 1993 Page 2 The currently proposed Comprehensive Plan Amendment to add the Alan Nettles property and a portion of the Orono sewer pond property to the Metropolitan Urban Service Area (MUSA) constitutes ou*- next Comprehensive Plan Amendment and therefore the expectation is that Met Council will not approve this amendment unless the Interim Strategy’ has beenivn'pUed with. The Interim Strategy has three specific requirements: 1. Adoption of Shoreland Regulations (Adopted Feb. ’92, DNR approval May ’93). 2. Adoption of National Urban Runoff Program (NURP) standards for storm water ponds. 3. Adoption of Best Management Practices (BMP’s) for construction sites. The NURP standards generally are a set of criteria for design of storm water ponds that addresses water quality issues as well as volume and storage. In general, this is done by requiring "wet" detention ponds that allow for settling and storage of suspended sediments by having the outlet higher than the bottom of the basin. Therefore, these ponds maintain a permanent water surface rather than draining dry a few days after a storm event. The Best Management Practices refer to an inch-thick volume published by MPCA entitled "Protecting Water Quality in Urban Areas". This document contains suggested methods and procedures for controlling urban runoff water quality via permanent structure (detention ponds, infiltration basins, filter strips, etc.), "housekeeping" practices (fertilizer management, catch basin cleaning, street sweeping, etc.), and construction site erosion atid sedimepLci^ntrol practices (temporary sediment basins, silt fence, outlet protection, etc.). Quoting directly from MPCA, a BMP is defined as "a combination of land use, conservation practices, and management techniques, which when applied to a unit of land will result in the oppommity for a reasonable economic return with an acceptable level of water
