Public Participation (cont.) Summary Types of BMPs Education and Technical Assistance Concerns with participation Funding Timeline

Assessment of Needs Identification of BMPs Quantification of BMPs Spatial Analysis Input from LSWCD BMP Database Analysis Technical Assistance and Education Input from LSWCD

Assessment of Needs Agricultural BMPs Livestock Exclusion 81 miles of perennial streams 32 miles of streamside fencing 83 Full Livestock Exclusion Systems 43 Horse Exclusion Systems 76 Hardened Crossings

Assessment of Needs Residential BMPs 20 Straight Pipes to be Corrected

Assessment of Needs Technical Assistance Agricultural LSWCD 5 technical man-years Residential VDH 2.5 technical man-years

Estimated Total Cost Agricultural BMPs $913,000 Residential BMPs $430,000 Technical Assistance$400,000 TOTAL $1.72 million

Livestock System Water Source$3,000 – $15,000 1,000 ft Streamside Fencing $4,000 – $8,000 TOTAL$7,000 – $23,000

Private Sewage System Septic System Repair $100 - $2,000 Septic System Replacement $7,000 Alternative System$9,000 – $36,000

Benefit Analysis Water Quality Benefits Human Health Environmental Benefit Economic Benefit Local Economy & Community Horse Owners/Boarders Agricultural Producers Homeowners

Milestones Implementation Milestones 20% of needed systems installed each year Water Quality Milestones Determined through modeling Monitoring

5-Year Timeline Implementation and Technical Assistance Exclusion Systems Straight Pipes Ag. TARes.TA Year(%) (FTE) TOTAL

5-Year Timeline Cost ($ Thousands) Exclusion Systems Straight Pipes Ag. TARes.TATotal Year($) TOTAL ,718

Targeting Agricultural Areas Selected Using Spatial Analysis Modeling Example: 50% livestock exclusion in North Fork Catoctin Creek without targeting: 26% violation of standard with targeting: 16% violation of standard

Monitoring VADEQ Currently funded Ongoing Loudoun Watershed Watch (LWW) Citizen based group Bacteria and benthic monitoring To document implementation progress

Education & Outreach LSWCD Newsletter specific to farmers One-on-one communication VDH Operation and maintenance of septic systems VCE Responds to specific needs of Virginia citizens LWW newsletter Displays at local events Updated website
