(A) Location map. The map shall show the site location with property lines in relation to surrounding roads, other geographic features, buildings and other structures.
(B) Topography.
(1) Topography showing two-foot contours for the site, invert elevations of existing storm sewer, and/or spot elevations of the conveyance system from drainage discharge points to the nearest receiving waterbody and for a minimum of 100 feet beyond the site boundary.
(2) Topography showing ten-foot contours for sub-watersheds upstream and downstream of the project site. Where topography in the region is characteristically flat or hydrologic flow path is undetermined, two-foot contours may be required.
(C) Vegetation map. In areas where there has been a natural resource or similar inventory, the map shall show the location of trees and vegetation on-site, with identification of those trees and vegetation intended to be retained.
(D) Landscape plan. The plan shall show proposed conditions and shall contain the following:
(1) Pervious area identified in square feet or acres;
(2) Seed mix(es) or other vegetation type(s) proposed;
(3) Note that vegetation must be established to 90% coverage with 100% coverage in areas of concentrated flow.
(E) Erosion and sediment control plan. The plan shall have both existing and final proposed conditions drawn to scale, shall be consistent with the manual Protecting Water Quality in Urban Areas (Minnesota Pollution Control Agency, 2000) as revised, and shall include the following:
(1) Proposed area of grading or other land-disturbing activities and delineation of the limits of disturbance including areas of grubbing, clearing, tree removal, grading, excavation, fill and other disturbance;
(2) Quantity of soil or earth material to be removed, placed, stored or otherwise moved on site;
(3) Locations and descriptions of proposed runoff control, erosion prevention, sediment control and temporary and permanent soil stabilization measures;
(4) A sequence of land alteration activity and corresponding implementation of erosion control practices, monitoring, maintenance and removal of erosion and sediment control measures; and permanent site stabilization measures. Prior to commencing activity (following all necessary approvals), the responsible party shall provide the SWCD with a construction schedule which will include approximate dates for the following:
(a) Completion of installation of perimeter erosion and sediment controls;
(b) Completion of required seeding and mulching activities;
(c) Completion of land-disturbing activities and putting into place measures for final soil stabilization and re-vegetation;
(d) When the site will be permanently stabilized and re-vegetated;
(e) When all temporary erosion and sediment controls will be removed from the site.
(F) SWPPP. The Stormwater Pollution Prevention Plan (SWPPP) developed for the site to meet National Pollution Discharge Elimination System/State Disposal System (NPDES/SDS) Phase II requirements shall be submitted as part of the applications.
(G) Wetland protection. The plan shall have both existing and final proposed conditions drawn to scale and shall contain the following:
(1) Delineated boundaries of wetlands as determined under the Wetland Conservation Act;
(2) Boundaries of wetland transition setbacks, if applicable per § 153.59;
(3) Computations/calculations used to design the wetland transition setback;
(4) Upon request, evidence of permits and process required under the Wetland Conservation Act (WCA).
(H) Monumentation. Plans for sites with buffers including wetland and shoreland setbacks, and sites with dedicated upland preserve areas must include monumentation locations and notes per § 153.64
.
(I) Topsoil management plan. The plan shall include the following:
(1) Carver County topsoil standard or a site-specific topsoil standard per § 153.62;
(2) Note that six inches of topsoil must be restored to all pervious areas;
(3) Note regarding the topsoil standard:
(a) For sites that have not been previously graded and/or linear reconstruction projects, the note must state that topsoil must meet the Carver County topsoil standard or an approved site specific topsoil standard. If topsoil does not meet the standard, it must be amended or topsoil meeting the standard must be imported to the site.
(b) For sites that have been graded after 2016, the note must state that topsoil must meet the Carver County topsoil standard or a previously approved site-specific standard for the site. If topsoil does not meet the standard, it must be amended or topsoil meeting the standard must be imported to the site.
(c) For non-linear sites that were mass-graded before 2016, the note must state that if topsoil does not meet the Carver County topsoil standard, two inches of compost must be added to the soil and tilled to a depth of six inches;
(4) Note that subsoil must be de-compacted to a depth of six inches prior to placement of topsoil;
(5) Location(s) where topsoil is to be reapplied;
(6) Quantity of topsoil needed to restore six inches in all pervious areas;
(7) Location of stockpile(s), if existing topsoil is to be stockpiled on site;
(8) Method of topsoil testing.
(J) Additional information as relevant and necessary to evaluate an application may be required. Requests for additional information shall be submitted in writing to the responsible party and shall specify requirements for submittal to the county.
