At a minimum, the storm water management plan shall contain the following information.
A. Existing site map. A map of existing site conditions showing the site and immediately adjacent areas, including:
1. The name and address of the applicant, the section, city and range, north point, date and scale of drawing and number of sheets;
2. Location of the tract by an insert map at a scale sufficient to clearly identify the location of the property and giving such information as the names and numbers of adjoining roads, railroads, utilities, subdivisions, cities and districts or other landmarks;
3. Existing topography with a contour interval appropriate to the topography of the land but in no case having a contour interval greater than 2 feet;
4. A delineation of all streams, rivers, public waters and wetlands located on and immediately adjacent to the site, including depth of water, a description of all vegetation which may be found in the water, a statement of general water quality, and any classification given to the water body or wetland by the Minnesota Department of Natural Resources, the Minnesota Pollution Control Agency, and/or the United States Army Corps of Engineers;
5. Location and dimensions of existing storm water drainage systems and natural drainage patterns on and immediately adjacent to the site delineating in which direction and at what rate storm water is conveyed from the site, identifying the receiving stream, river, public water, or wetland, and setting forth those areas of the unaltered site where storm water collects;
6. A description of the soils of the site, including a map indicating soil types of areas to be disturbed as well as a soil report containing information on the suitability of the soils for the type of development proposed and for the type of sewage disposal proposed, and describing any remedial steps to be taken by the developer to render the soils suitable;
7. Vegetative cover and clearly delineating any vegetation proposed for removal; and
8. 100-year floodplains, flood fringes and floodways.
B. Site construction plan. A site construction plan including:
1. Locations and dimensions of all proposed land disturbing activities and any phasing of those activities;
2. Locations and dimensions of all temporary soil or dirt stockpiles;
3. Locations and dimensions of all construction site erosion control measures necessary to meet the requirements of this Chapter;
4. Schedule of anticipated starting and completion date of each land-disturbing activity including the installation of construction site erosion control measures needed to meet the requirements of this Chapter; and
5. Provisions for maintenance of the construction site erosion control measures during construction.
C. Plan of final site conditions. A plan of final site conditions on the same scale as the existing site map showing the site changes including:
1. Finished grading shown at contours at the same interval as provided above or as required, to clearly indicate the relationship of proposed changes to existing topography and remaining features;
2. A landscape plan, drawn to an appropriate scale, including dimensions and distances and the location, type, size and description of all proposed landscape materials which will be added to the site as part of the development;
3. A drainage plan of the developed site delineating in which direction and at what rate storm water will be conveyed from the site and setting forth the areas of the site where storm water will be allowed to collect;
4. The proposed size, alignment and intended use of any structures to be erected on the site;
5. A clear delineation and tabulation of all areas which shall be paved or surfaced, including a description of the surfacing material to be used; and
6. Any other information pertinent to the particular project which, in the opinion of the applicant, is necessary for the review of the project.
