Protect Stream and Wetland Vegetated Buffers
P2Protect Stream and Wetland Vegetated Buffers

Why this matters to the lake?
The biological and physical processes occurring in healthy streams, wetlands, and their vegetated buffers reduce pollutant loads to the lake. Healthy streams and wetlands function as “kidneys” for the lake, actively improving water quality through biological processes before it reaches the lake. Buffers significantly improve the ability of streams and wetlands to improve water quality. Buffers capture sediment and reduce turbidity in the lake. Buffers also mitigate runoff temperatures, provide shade for small streams, and facilitate infiltration, which creates healthier streams and wetlands.
Intent
- Preserve Lake George water quality by protecting vegetated buffers around streams (both perennial—those that flow year round—and intermittent—those that only flow during certain periods) and wetlands that flow to the Lake
Recommended Methods
Create a site plan that maintains buffers where existing native trees, vegetation, and soils are not disturbed. Non-native and/or invasive species may be removed. Lawn areas should not encroach on buffer areas. Consider reducing existing stream crossings and avoid new crossings.
Requirements
Based on site conditions, indicate on the Proposed Site Plan the appropriate buffer width:
| Category | Setback from Edge of Bank |
Points | Points with Covenant |
|---|---|---|---|
| Basic | 35 feet | Required | 3 points |
| Preferred | 75 feet | 3 points | 4 points |
| Optimal | 100 feet | 4 points | 5 points |
Prerequisite: Sites that locate new structures in a previously undisturbed area within 75 feet of the bank or edge of a wetland and/or clear native vegetation within 75 feet of the bank or edge are not eligible for certification. Permanent markers must be installed to indicate the buffer boundary for long-term maintenance purposes. This prerequisite does not apply to existing buildings and structures that are being redeveloped.
Five points will be awarded for selection of a site without this site constraint (no streams or wetlands).
Submittals
Include the following information with application:
- As part of the Proposed Site Plan, show all streams and wetlands—both perennial and intermittent—and the proposed buffers. Indicate location of permanent markers to delineate buffer.
- Copy of legal covenant (if applicable).
