Rice Creek Watershed District Watershed Management Plan Chapter 8. Watershed Plan Administration content are intended to supplement Minnesota laws and rules relative to Local Plan content. The RCWD has set two levels of requirements for the content of Local Plans: • Level 1 — The level of detail is designed for those communities that do not wish to assume permitting authority from the RCWD. • Level 2 — Requires additional information and detail for some of the Local Plan requirements for communities that choose to assume all or some of the permitting authority from the RCWD. The RCWD has considerable technical resources available to address water and resource issues. The RCWD encourages communities to use as many of these resources, including monitoring data, models and modeling results, management studies, GIS information and similar information, to meet these requirements. Although RCWD has completed hydrologic, hydraulic, and water quality modeling throughout the District, communities may need to perform additional modeling in areas where they intend to assume local regulatory authority, to show compliance with the content of the WMP. The general standards for the Local Plan which the requirements of MS 103B.235 Subd. 2 are as follows: 1. Describe the existing and proposed physical environment and land use. At a minimum this must include land use /zoning maps for both present and future conditions, and a land cover /classification map such as the Minnesota Land Cover Classification System (MLCCS). Define drainage areas and the volumes, rates, and paths of stormwater runoff. Municipalities, for both Levels 1 and 2, should also include a map of the stormwater system that shows stormwater ponds, streams, lakes and wetlands; structural pollution control devices (e.g., grit chambers, separators); pipes and pipe sizes, ditches and any other conveyances; and outfalls and all other points of discharge from the system. An inspection and maintenance system schedule should be included. The appropriate portion of the MS4 SWPPP prepared in accordance with Permit No. MNR040000 can be incorporated by reference to satisfy this requirement. (a) Level 1 — the Local Plan does not need to include information relating to stormwater rate and volume. Evidence of a storm water master plan or similar document is sufficient. (b) Level 2 — the Local Plan must include information on existing and proposed stormwater rates and volumes based on full build out taking into account implementation of the local regulatory controls. The information should be related to those volume and rate control locations within the District and include analyses at Regional Assessment Locations. 2. Identify the methods and means to achieve Rule C, Part 5, Water Quality and Volume Control of the RCWD rules. This applies only to Level 2 communities. 3. Identify areas and elevations for stormwater storage adequate to meet Rule C, Part 6, Peak Stormwater Runoff Control of the RCWD rules. This applies only to Level 2 communities. 4. Generally discuss or identify approaches, methods, means, procedures, ordinances or plans being used to achieve compliance with RCWD rules or identify reliance on the RCWD for municipal review and compliance with stormwater management requirements. (a) Level 1 — communities must provide a specific statement that they request RCWD to continue to implement its rules and regulations and issue permits within the City/Town.
