Neighborhood Source Assessment Friday, November 6, 2015

Unified Subwatershed and Site Reconnaissance (USSR) Developed by

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 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.

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

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.

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

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

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

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

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

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

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

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)

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

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

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

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

Other Assessment Forms Hot Spot Pervious Area Streets and Storm Drains

What Would You Do Here?

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.

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

Clean Water Communities

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!

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.

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

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
