A project partnership which has increasedcollaboration between many agencies
…and others including consultants, local agencies an NGO’s
Once begun is half done.

The difficult part of a new project…
GETTING STARTED!
The Solution?
The Watershed Resources Registry (WRR)
• A user‐friendly online mapping tool available to everyone when considering resource conservation and environmental planning
• Provides results to 8 GIS models for preservation and restoration and access to substantial other GIS data
• Easy access to spatial information as preparation for regulatory and permitting requirements
“One stop shopping” that covers many primary project planning procedures
Initially designed for transportation projects and land use planning but is valuable for many applications
Provides information to consider for:• CWA Sections: 319, 401, 402, 404, and 303(d)• Section 7 – Endangered Species Act• NEPA reviews• Expedites watershed planning, mitigation siting,
TMDL and stormwater issues
Includes spatial data on significant ecological resources (e.g. Delaware Ecological Network – DEN)
Eight GIS‐Based AnalysesContractor: Maryland Environmental Service
ESRI Software, with model builder
• Analysis uses spatial data as input to the models• Some spatial data are informational only where they are in
a “turn‐on/turn‐off” overlay• Input spatial data scored to give value by polygon where a
scoring of 1‐5 stars is used.• Presence of multiple ecological resources gets a higher star
rating (streams, wetlands, forests, protected lands)
The models for Phase 1 of the Delaware WRR
1. Preserve Uplands2. Restore Uplands3. Preserve Wetlands4. Restore Wetlands5. Preserve Riparian Zones6. Restore Riparian Zones7. Preserve Natural Stormwater Systems8. Restore Degraded Stormwater Systems
FactorsforWetlandPreservation
RelativeFactors: Is a forested area
in a Green Infrastructure core or corridor
within 200 feet but not in a protected lands
within 300 feet of a stream
within 300 feet of an ERES water feature
Is a Category I wetland
Within 500 feet but not in mitigation site
In a 100yr/500yr floodplain
Within 100 feet of a well head protection area or excellent ground
water recharge area
In Groundwater management zone
Impervious area coverage
AbsoluteFactors:• Must be a wetland
• Cannot already be protected
The Delaware WRR Technical Advisory Committee (TAC) met for more than 6 months to determine criteria for each of the 8 models
