Green Shores Rating System Voluntary credit rating system
designed to promote sustainable coastal development
Modelled after LEED™
Credits – 1) action based; 2) require minimal professional “sign-off”; 3) verified through permit documents & a site visit
“Defines” green shores for residential property
Builds local capacity through trained Green Shores for Home verifiers.

How Does the Rating System Really Work?
• Rating system evaluation Submittal information required Ease of scoring each site Credit categories
• Results of evaluation
• Adjustment to rating system

Credit Categories 3 Main Categories • Shoreline Processes
Bulkhead removal Setbacks
• Shoreline Habitat Riparian vegetation Large woody debris
• Water Quality Impervious surface Pesticide/herbicide/fertilizer
• Monitoring required or bonus points, what if you don’t do something, i.e. don’t put in a bulkhead, don’t cut down trees, the roll of LWD in different environments.
![Page 27: Incentivizing Low Impact Development: Developing and ... · Technical Team develops and tests GSH credit system. 2. Local government partners indentify incentives. 3. Local governments](https://reader034.fdocuments.in/reader034/viewer/2022050204/5f57f0bd594f930c89335fd9/html5/thumbnails/27.jpg)
What Did We Learn and What Did We Change?
• All sites are not created equally - site conditions influence what can be done on site
• Example - Parcel size, urban/rural, freshwater/marine
• Difference in LWD function in the marine environment compared to a lake environment.
• Result adjusted rating system so smaller wood is favored in the lake environment LWD okay for marine environment

What Did We Learn and What Did We Change?
• Most important - condition of site at the completion of project
• Award credits for saving trees • Don’t “penalize” a site that
doesn’t have a bulkhead & isn’t adding one
• Adjusted rating system • Implementation June 2015

Bonus Information
• Lake WA property owners
• What motivated the home owners to green their shoreline?
• Attracting a lot of attention from recreational boaters
