2 CWMTF Program Areas Acquisition Restoration Stormwater Wastewater 2

3 Acquisition of Riparian Buffers CWMTF funded approximately 750 acquisition projects awarded over $523M for fee simple and conservation easements acquisition Grant recipients have provided 57% match 3

4 Donated Easement Minigrants CWMTF funded approximately 170 donated easement minigrants awarded over $3.9 M ($25,000 cap) Grant Recipients have provided 95% match 4

5 Acquisition of Riparian Buffers Water Quality Benefits filters sediment and other pollutants assimilates nutrients slows velocity of runoff regulates stream temperature provides food and bank habitat 5

6 Acquisition of Riparian Buffers Secondary Benefits provides corridor for greenways provides recreational opportunities protects downstream resources protects current and future drinking water supplies creates wildlife corridors improves air quality prevents flood damage 6

11 Clear cutting of large areas was prevented. This halted de-watering and protected pristine waters of the Alligator River & its many tributaries.

12 Most of the areas acquired fee simple have been placed in the NCWRC gamelands program and are open to public hunting. Wildlife habitat was dramatically improved in the area with controlled burning & plantings

13 Canoeing opportunities have been provided Davis at & numerous Kilkenny Tract locations on the protected View From tracts Hwy 94 Bridge

14 Alligator R Mattamuskeet Ventures Farm Alligator River restore natural drainage to Alligator River CWMTF, NC Coastal Federation, and federal agencies have begun one of the largest restoration efforts in the country rerouting agricultural runoff from 42,500 acres of drained farm land back to its natural drainage pattern thus protecting area quality shellfish waters. Lux Farm Pamlico Sound

15 CWMTF has participated in 12 projects ,071 total acres under conservation $14,720,040 CWMTF funds for buffer acquisition $21,925,363 Total funds for buffer acquisition $1,753,734 CWMTF funds for restoration design and construction $3,524,761 Total funds for restoration design and construction

16 Alligator River Watershed Federal, State, and non-profit organizations protecting Outstanding Resource Waters Shellfish waters Primary Nursery Area Exceptional wetlands Extensive wildlife habitat Old-growth timber Public access for recreation and hunting

17 Stream Restoration CWMTF funded approximately 175 stream restoration projects awarded over $116M for stream restoration Grant recipients have provided 58% match 17

18 Stream Restoration Water Quality Benefits Banks: protected from erosion, shade cools the stream Buffers: sustain banks, filter upland sediment and pollutants Floodplains: spread/slow flow, carried sediments can deposit Habitat: improved, aquatic and terrestrial Other Benefits Drinking water: protect source waters, less need for treatment Destructive flooding: property damage usually reduced Aesthetics: more attractive and inviting 18

28 Successful Recovery 6+ miles of riverfront restored 121 structures on 14 sites $2.5 Mil CWMTF has leveraged $1.5+ mil $1.45 mil in State and Federal funds $127,500 private landowner contributions Average Cost per Linear Foot of $73.21 Today Rates as Fully Supporting

29 Stormwater BMPs CWMTF funded approximately 150 stormwater BMP projects awarded over $59M for stormwater BMPs Grant recipients have provided 56% match 29

30 Stormwater Best Management Practices (BMPs) Water Quality Benefits Stream banks: erosion reduced; runoff rate/volume reduced Downstream lakes/streams: protected; sediment and other pollutant load captured; groundwater replenished and stream base flow supported Habitat: aquatic protected; all the above Other Benefits Drinking water: protect source waters, less treatment needed; harvest/reuse rainwater, less demand for treated water Destructive flooding: property damage reduced Aesthetics: can be landscape amenities 30

37 BEFORE Runoff first enters the forebay Sediment and pollutants settle out Designed to be cleaned out periodically Forebay

38 Runoff Next flow first enters the the wetland forebay Sediment Sinuous path and maximizes pollutants contact settle out and retention time Designed Nutrients to and be pollutants cleaned out are periodically further removed through plant and soil interactions Forebay Constructed wetland

39 Finally Finally flow flow leaves leaves through through the the outlet outlet structure structure Difference Difference between between normal normal pool pool elevation elevation and and outlet outlet overflow overflow is is storage storage available available for for attenuating attenuating runoff runoff Reduces Reduces the the peak peak flow flow rate rate downstream downstream = = storage storage

41 Past: Fred Fletcher Wetland ($1.1M CWMTF) Edna Metz Park / Smallwood Drive Stabilization ($2.3M match) City of Raleigh Maintenance Yard BMPs Present: Peace College Rainwater Harvesting & Reuse ($750K CWMTF / $433K match) Future: Capital Boulevard Corridor Study Improvements for pedestrian, bicycle and vehicular traffic; and support private redevelopment efforts Vision includes daylighting and enhancing the stream and more stormwater BMPs

42 Wastewater Infrastructure Projects CWMTF funded approximately 285 wastewater infrastructure projects awarded over $250M for wastewater project Grant recipients have provided 64% match CWMTF is required by statute to include economic distress in project funding prioritization.

43 Wastewater Infrastructure Projects Water Quality Benefits: Reduction of pollutant loading to surface waters. Protection of unpolluted waters. Improvement of degraded waters. Secondary Benefits: Reduction of health threats. Improvement of surface waters for recreational use. Reuse projects reduce the demand for water supply from groundwater & reservoirs. Infrastructure construction creates jobs. Project Types: Elimination of failing septic systems, straight pipes, & privies Sewer collection system rehabilitation Regionalization Wastewater treatment plant repair & upgrade Reuse of treated effluent

44 Elimination of failing septic systems, straight pipes, & privies eliminates surface water pollution from these sources Dover Collection systems and Regionalization in the Core Creek watershed Straight Pipe Cove City

45 Sewer collection system rehabilitation decreases: - overflows of raw wastewater to surface waters, - impaired treatment due to overloading at WWTPs, and - overloading of land disposal sites. Franklinton Sewer Overflows UT Cedar Creek Conway Sprayfield & WWTP overloaded Overland Flow to Indian Creek

46 Regionalization eliminates a WWTP and its discharge or prevents establishing a new WWTP discharge by combining wastewater treatment at one WWTP. Wastewater treatment plant repair & upgrade improves WWTP performance & reduces pollutants in the effluent that is discharged, land disposed, or reused. Elkin, Ronda, Jonesville Project: Details from Bern coming up next.

47 Reuse of treated effluent reduces the volume of effluent discharged to surface waters. Johnston County - End users include a golf course, greenhouse irrigation, wet decks at lumber yards, and non-potable uses in three buildings at Johnston County Community College. 47

48 Wastewater - Regionalization Ronda Elkin, Jonesville, and Ronda PROBLEM: 3 WWTPs within 1 mile all needing repair. Wilkes HS Failing septic systems in area with No Service All wanting own system 48

49 Three systems eliminated CWMTF invested $3M of a total $6.4M Rural Center contributed additional $3M Total cost of upgrading each system estimated $15M - $18M Chatham Manufacturing WWTP Surry County eliminated Sand Filter System - East Wilkes HS, Wilkes County eliminated Jonesville WWTP, Yadkin County- eliminated 49

50 Elkin WWTP best suited to become regional system for Elkin, Jonesville, Chatham Manufacturing, East Wilkes High School and failing septic systems in Ronda, but needed upgrades 50

51 Wilkes Co. $3M Rural Center Grant for sewer and connection to Elkin Remove Failing Septic Systems

52 CWMTF grants encouraged 3 separate towns in 3 counties Plus a Private Industry and a School to all agree to Regional System. CWMTF funds helped Upgrade Elkin Plant, Repair a Trunk Line and install Interconnect.

53 Permitted Flows Town of Elkin Wastewater Regionalization with Chatham, Inc. and Town of Jonesville: Loading Analysis at Permitted Flows Current MGD Combined MGD TSS Loading BOD Loading lbs/day Combined total would go to 6.8 MGD w/o Consolidation Why a Success: -3 Counties, 3 Towns put aside Political Turf for Better System -Having Each Applicant have Own Waste Water Treatment System would have Cost Millions More -Long-Term Maintenance Costs will be lower (maintain system) -Improved Treatment means better WQ -Applicants Very Happy with Regional System - Now Model used by Division of Water Quality to others
