1. Neighborhood Source Assessment
Friday, November 6, 2015

2. Unified Subwatershed and Site Reconnaissance (USSR)
Developed by

3. On a subwatershed scale.
Designed to:
Identify Pollution Sources
Identify ways to manage pervious surfaces, utilities and public areas to benefit water quality.
Identify potential upland restoration projects.
Assess a subwatershed pollution index and potential for restoration.
On a subwatershed scale.

4. 4 Components of the USSR Neighborhood Source Assessment
Hot Spot Investigation
Pervious Area Assessment
Streets and Storm drains
We are going to concentrate on Neighborhood Source Assessment, since it will be most useful to you… In your binder, you will find the other forms. On your thumb drive, you will find the full CWP presentation on USSR. There is also inforamtion on the CWP website which can assist you in doing the other parts of the assessment.

5. Neighborhood Source Assessment
Yards and Lawns
Driveways, Sidewalks, and Curbs
Rooftops
Common Areas

6. Getting Ready to Conduct a Neighborhood Source Assessment
Maps
Subwatershed level
Equipment (Camera, clip board, forms, map)
Staffing
Two person team, about 1 to 2 square miles/day
Moderate level training
Desktop Analysis
Predetermine neighborhoods, hotspots, and pervious areas
Show form on Doc Cam – Point out the various parts of form.

9. Neighborhood Source Assessment
Part A: Neighborhood Characterization
Neighborhood Name?
Lot Size?
Estimated Age of Neighborhood?
Percent of homes with garages? Basements?
Sewer service?
Infill, Redevelopment, remodeling?
GO to GIS = look at neighborhood, septics, size of lots age is 50s, 2000s

10. Part B: Yard and Lawn Conditions
% of lot with impervious cover?
% of lot with turf grass?
% of lot with landscaping?
% of lot with bare soil?
Looking at the neighborhood, you want to answer these questions on a neighborhood scale… not per household. Describe the circles vs. diamonds

11. NSA: Yard & Lawn
Proportion of total neighborhood turf lawns with the following management status:
Medium
Low
High

12. Part C: Driveways, Sidewalks & Curbs
% of driveways that are impervious?
Are driveways clean? Stained? Dirty? Breaking up?

13. Part D: Rooftops % Directed to Impervious Surface?
% Directly Connected?
% Discharge to Pervious Area?
Room for a Rain Garden?
% Discharge to Rain Barrel?

14. Part E. Common Areas Designated Use Undesignated Use
Buffer Encroachment
Open space present?
Pet waste? Dumping?
Buffer encroachment?

15. Part F. Recommendations
Reducing Pollution Sources through Behavior Change
Residential RainScaping Actions
Pollution Severity
Restoration Opportunity Index
Community Property Opportunities
Potential Pollution Source
Restoration Opportunity

16. NSA Pollution Severity Index
Severe (More than 10 circles checked)
High (5 to 10 circles checked)
Moderate (Fewer than 5 circles checked)
None (No circles checked)
Neighborhood Restoration Opportunity Index
High (More than 5 diamonds checked)
Moderate (3-5 diamonds checked)
Low (Fewer than 3 diamonds checked)

17. Yards and Lawns Stewardship Technique Problems Reduced fertilizer use
Reduced pesticide use
Xeriscaping /Education
Natural landscaping
Tree planting
Yard waste composting
Erosion repair
Single lot control
Septic system clean-outs
Safe pool discharge
Problems
High management turf
Potential pesticide use
Non-target irrigation
Extensive turf cover
Low forest canopy
Improper yard waste disposal
Soil erosion
Construction activity
Presence of septic systems
Presence of swimming pools

18. Driveways, Sidewalks, and Curbs
Problems
Driveway/curb flows
Driveway conditions
Outdoor car maintenance
Sidewalk in bad condition
Stewardship Technique
Safe car washing
Driveway sweeping
Car fluid recycling
Pet waste pick-up, Streetscaping

19. Rooftops Problems Downspout connection Stewardship Technique
Rain Barrels
Connect Downspout to Rain Garden or other pervious area

20. Common Areas Problems Evidence of pet waste Stormwater ponds
Turf cover in open space
Condition of storm drain inlets
Sidewalk zone
Evidence of dumping
Stewardship Technique
Pet waste education
Stormwater maintenance
Bufferscaping, reforestation
Storm drain stenciling
Streetscaping
Dumping prevention

21. Other Assessment Forms
Hot Spot
Pervious Area
Streets and Storm Drains

22. What Would You Do Here?

23. Put It All Together
Identify Parts of the Neighborhood with Highest Pollution Severity
Identify Parts of the Neighborhood with Highest Restoration Potential (low hanging fruit)
Create A Plan:
1-2 Rainscaping Practices
to promote
1 Behavior to Change.
Show ppt example
Identify Major Pollution Sources.
Identify Major Restoration strategies. Map potential restoration projects.
Create a strategy for Engaging Your Community.

24. Your Challenge…
Choose 1 or 2 Stewardship behaviors or best management practices to promote in your community.

25. Clean Water Communities

26. Clean Water Communities
A tool for Stewards or other leaders to engage their Communities in real, quantifiable
pollutant load reduction.
A tool for AA COUNTY to quantify
private property efforts to reduce pollution.
A tool for all of us to reach outside the
CHOIR to engage communities
in being part of the Solution!

27. Clean Water Communities Certification will:
1. Be accessible across all socio economic and geographic areas of our county.
2. Be simple enough to be widely adopted.
3. Maintain a rigorous pollutant reduction standard.

28. Clean Water Communities Certification Goal # 1: Assist communities in reducing stormwater runoff by applying RainScaping Solutions
In the pilot phase, Communities must reduce runoff by 20% in a target area of their community (minimum of 10 contiguous parcels) by installing on lot BMPs such as:
Rain Barrels/Cisterns
Downspout Disconnection
Rain Gardens and Bioswales
Infiltration Trench/Dry Well
Stormwater Planters
Grass or Tree Buffers
Tree Planting
Conservation Landscapes (turf removal)
Pervious Hardscapes
Green Roofs
Maintaining/retrofitting existing BMPs

29. Clean Water Communities Certification Goal # 2: Change behaviors to reduce pollutant sources
Communities must achieve 100 behavior points by obtaining commitment of 30% of their ENTIRE community to reduce pollution through behavior changes.
Behaviors Include:
Urban Nutrient Management (Clean Lawncare)
Pet Waste Disposal / Dumpster Management
Managing Yard Waste (keeping leaves and debris off of impervious surfaces and away from stormdrains)
Reducing Energy
BMP on marinas, golf courses or agricultural land
Septic Maintenance
