Grading, Drainage, and ESC Plan (C1.1) · Grading and construction within Ramsey County right-of-way will require a Ramsey County right-of-way permit. Update these plans with any County requirements (retaining wall removal, guard rail removal, etc.) Response: Rasmey County provided comments on August 11th. Their primary request was to remove the retaining wall and guard rail. The developer does not wish to do this as it would increase grading costs, require replacement of the existing gas line, and remove existing screening vegetation. A small portion of the guard rail will necessarily need to be removed for the entrance. · Temporary and final stabilization methods are tabulated in the SWPPP on sheet C4.2 but are not depicted visually in sheet C1.1. Define the temporary and permanent erosion control and final stabilization methods. o Steep slopes 3:1 or greater should be vegetated with a low or no maintenance plant types. Response: An additional plan sheet (C1.2) has been added to the plan set. This is an erosion and sediment control plan. It denotes the 3:1 slopes areas (approximately) that should be restored with low maintenance seeding (MnDOT Seed Mix 25-131.) o The filtration basin detail and notes on sheet C3.6 have good information are a little open ended. Response: The detail has been revised to (hopefully) provide additional clarity. · Provide silt fence at all downgradient locations around the development to prevent erosion from leaving the site (this pertains to the majority of the development perimeter). Response: Additional silt fence (or bio-rolls) have been added along the west and east property lines. Since the existing trail is a highpoint and is draining toward the property, no silt fence is shown along the north and northwest property lines. · Show individual tree locations along western plat boundary. Include notes in the grading plan to protect existing trees. Response: This survey work has not been completed at the time of the revised plan preparation.
