Re: Conditions #37 of the OOC
Dear Commissioners,
As required by Condition #37 of the Order of Conditions issued for the project located at 60 Damon Road, we are providing a detailed sequencing, construction, and planting plan for
the riverfront mitigation areas noted on the approved plans. While three separate mitigation areas are shown on the plans, the description below is applicable to all three.
Install erosion control barrier along the downgradient edge of the mitigation areas and along the side slopes as necessary to adequately contain potential runoff and sediment relocation.
Confirm sedimentation controls are adequate with Conservation Commission agent.
Remove existing asphalt or gravel surfacing within restoration areas to a minimum depth of 6”. Remove and dispose off site.
Import and spread clean topsoil to a minimum depth of 6” following compaction. Final surface grades should match previous grades and/or conform to the existing topography as best as
possible.
Seed areas with Conservation Mix as specified and mulch with straw or equal.
Water as required to ensure adequate germination.
Review final restoration areas with Conservation Commission agent.
Remove erosion control barriers once areas are stabilized.
