7.1 Local Plan Content
Local water management plans are required to conform to Minnesota Statutes Chapter 103B.235, Minnesota Rules 8410, and this Plan. Minnesota Rules 8410.0160 establishes the structure the LWMP must follow; Section 8410.0170, not reproduced here, describes the required sections in more detail.
8410.0160 GENERAL STRUCTURE. Each local plan must, at a minimum, meet the requirements for local plans in Minnesota Statutes, section 103B.235, except as provided by the watershed management organization plan under part 8410.0110, subpart 3. Each local plan must include sections containing a table of contents; purpose; water resource related agreements; executive summary; land and water resource inventory; establishment of goals and policies; relation of goals and policies to local, regional, state, and federal plans, goals, and programs; assessment of problems; corrective actions; financial considerations; implementation priorities; amendment procedures; implementation program; and an appendix. Each community should consider including its local plan as a chapter of its local comprehensive plan.
The policies and goals established by the local water management plan must be consistent with this Plan. The local water management plan must include in its assessment of problems those problems identified in this Plan that affect the community, as well as any problems identified in the HHPLS and not incorporated here. Each city participated in the development of the HHPLS and was provided a copy of the HHPLS findings. A copy of the study is available from the District. The assessment must also include an analysis of the maintenance and management issues identified in Minnesota Rules 8410.0100.
The general standards for local water management plan content incorporating the requirements of Minnesota Statutes 103B.235, subdivision 2, and this Plan are as follows:
- Describe the existing and proposed physical environment and land use.
- Define drainage areas and the volumes, rates, and paths of stormwater runoff, including a map of the stormwater system.
- Include a stormwater system map that shows ponds, streams, lakes and wetlands that are part of your system; structural pollution control devices (grit chambers, separators, etc.) that are part of your system; pipes and pipe sizes and other conveyances in your system; and outfalls and all other points of discharge from your system that are outlets.
- Identify areas and elevations for stormwater storage adequate to meet performance standards established in the subwatershed plans.
- Identify areas of known flooding and areas identified in the HHPLS where modeling predicts that public roads, private roads, or private drives might overtop during infrequent events or there may be minimal freeboard above the flood level. Local plans must assess whether the risk of occasional flooding is acceptable or should be addressed, and set forth a plan for making improvements as necessary.
- Identify land-locked subwatershed units and basins and strategies to manage water volumes in those land-locked areas to minimize flooding.
- Assess the condition of locations identified in the HHPLS where modeling predicts that under existing or future development conditions higher velocities than desired may result in erosion at outlets or culverts, potentially warranting erosion control or energy dissipation. The local plan must assess the need for such measures, and set forth a plan for making improvements as necessary to correct existing or prevent future erosion.
- Define water quality and water quality protection methods adequate to meet performance standards established in the watershed plan.
- Identify specific steps the LGU will take to achieve the annual phosphorus load reductions it is assigned in the subwatershed plans affecting their community. Credits for existing BMPs in-place will be considered through the Local Surface Water Management Plan and evaluated on a case-by-case basis.
- Identify regulated areas, such as Outstanding Resource Value Waters.
- Identify Key Conservation Areas in this Plan in their community, and assess the adequacy of local policies and regulatory controls in place to conserve hydrologic and ecologic values of the resources within those Areas. The plan must set forth a plan and schedule for the amendment of those policies and controls as necessary to meet performance standards established in the subwatershed plans.
- Assess the consistency of the LGUs wetland regulation, including any wetland classification system and specific wetland classifications, with the management classifications, classification system and proposed regulation set forth in this Plan.
- Set forth an implementation program, including a description of official controls and, as appropriate, a capital improvement program.
- Describe the LGUs permitting process for land and wetland alteration work, including an assessment of the adequacy of current official controls and a plan and schedule for the amendment of those controls as necessary.
- Describe the LGUs conformance with NPDES requirements for MS4s including TMDL and Nondegradation requirements. The local plan must include the LGU’s Stormwater Pollution Prevent Plan (SWPPP) or a summary of its contents.
