Stormwater Plan Stormwater Plan
The construction stormwater plan and erosion and sediment control plan follow NYS
best practices for residential construction as outlined in New York State Standards and
Specifications for Erosion and Sediment Control, Appendix D, and Queensbury
Environmental and Performance Standards. Measures to be implemented during
construction will include minimizing area of impact, soil containment and stormwater
containment measures. It should be noted that there will be no site excavation or
clearing as part of this project, and the proposed deck and construction limits will remain
within the existing site footprint. Current best practices will be utilized during
construction to reduce site impacts and reduce surface stormwater runoff from the
project site.
These measures include, but are not limited to:
• Silt fence installed around site perimeter, including coir logs placed along the
southern (lakeward) construction boundary
• Only foot access to/from site utilizing existing wooden and stone stairs and paved
trails
• Negligible surface soil disturbance le. no planned excavation or grading
• Roof rainwater catchment directed away from construction site utilizing existing
gutters and downspouts
• Existing vegetation will remain in place and protected throughout construction
Proposed conditions will retain existing stormwater infrastructure onsite, and reduce
exposed soils on site under current conditions. A drainage rock pad will be constructed
at ground level beneath the proposed deck footprint to reduce surface runoff and
improve infiltration. The plan includes a level 6-8" layer of drainage gravel to be placed
within the existing (and proposed) deck footprint. Wooden framing and landscape fabric
will be installed to contain this gravel pad. The intent of this design is to reduce the
exposed soil footprint within the property and minimize runoff and sediment transport.
Given the area under the proposed (and existing) deck does not receive sufficient
sunlight to successfully install vegetation for erosion control and stormwater protection,
porous gravel media is a preferred alternative and a significant improvement from the
exposed soils under existing conditions.
