The bank includes unnamed tributaries to Doyles Creek. Phase 2 includes approximately 66,666 linear feet of stream channel. What is the function of the construction activity? ❑ Residential ❑ Commercial ❑ Industrial ❑ Road Construction ❑ Linear Utility ® Other (please specify): Stream Restoration 2.6.2 Size of Construction Project What is the size of the property (in acres), the total area expected to be disturbed by the construction activities (in acres), and the maximum area expected to be disturbed at any one time? Total Area of Development = 103.2 acres Estimated Area to be Disturbed = 9.9 acres 2.7 SEQUENCE AND ESTIMATED DATES OF CONSTRUCTION ACTIVITIES Pre -Construction: 1. The Contractor shall be responsible for determining the exact locations of all existing utilities within the projects area prior to construction operations and must contact Miss Utility (811) prior to the commencement of any construction activities. The Contractor must arrange a pre -construction meeting with Charlotte County and the Southside Soil & Water Conservation District. Phase 1 — Site Preparation: 1. Install stone construction entrances per Std. & Spec. 3.02. 2. Install silt fence, super silt fence, and tree protection where shown. M 2.9 STORMWATER POLLUTION PREVENTION PLAN — INNISFREE STREAM MITIGATION BANK SITE EVALUATION, ASSESSMENT, AND PLANNING 3. Install Phase 1 erosion and sediment control measures according to standards set forth in the Virginia Erosion and Sediment Control Handbook, Third Edition 1992. These measures shall be implemented prior to the commencement of any earthwork activities on -site. 4. Upon approval of County Staff, commence with tree removal, clearing, and grubbing operations. Tree removal, clearing, grubbing, and any demolition shall be performed in phases to minimize earth disturbance during construction. 5. Concurrent with the tree removal and clearing and grubbing operations, Contractor shall install timber mats, mulch access road stabilization, and/or gravel access road stabilization. Installation shall be progressively in advance of heavy equipment used to place these practices such that the weight of the equipment is borne by previously installed section of the road as it is constructed. 6. Invasive plant species within the LOD shall be removed and/or controlled as detailed. 7. It is the intent of these plans to avoid clearing to the greatest extent practical. However, clearing and grubbing operations shall proceed as necessary to facilitate earthwork activities. Existing vegetation called out to be preserved shall be protected from disturbance and compaction of heavy equipment. All additional cleared woody vegetation shall be removed, chipped, stockpiled, and used for organic matter on -site. 8. Protect all sanitary sewer pipes, manholes, existing dry utilizes (e.g. electrical, gas, cable, phone, TV, etc.) and storm sewer pipes crossed throughout the project using timber matting or approved alternative. 9. Contractor shall only grade an area that can be stabilized within the same day. 10. At completion of Phase 1, all E&S Phase 1 protection measures, access roads, staging areas, shall be established. Phase 2 — Channel Construction: 1. Construction activities shall be performed in reach segments in an effort to minimize disturbance. a. Upon approval by Engineer/Designer and the County, the Contractor may proceed with grading, stabilization, and restoration activities for the tributaries. b. Within a respective reach segment, instream work should be done from upstream to downstream. 2. All work withing the stream channels shall be performed in the dry. Approved clean water diversion measures (check dam, pump around diversion pump with dewatering bag) shall be utilized to ensure that sediment laden water is not discharged into the stream channel. The clean water diversion shall be of sufficient length to ensure that all work within the daily work zone is performed in the dry. 3. The daily construction segments shall be determined by the Contractor, but the stream will be permanently or temporarily stabilized and reconnected at the end of each workday. 2.10 STORMWATER POLLUTION PREVENTION PLAN — INNISFREE STREAM MITIGATION BANK SITE EVALUATION, ASSESSMENT, AND PLANNING 4. Pump around diversion shall not be operated at night, unless approved under separate cover by County. 5. Contractor shall salvage stream bed substrate material from the existing channel. This material will be used as infill for streambed reinforcement areas. 6. Installed E&S measures (e.g. tree protection, silt fence, super silt fence, and safety fence) to remain in place until final stabilization of all disturbed areas has been achieved. 7. Commence with grading of the new stream channel, sections, profile, and installation of grade control structure as construction moves downstream. 8. During grading operation, strip existing topsoil and stockpile separately. Topsoil must be free of unsuitables. Stripped topsoil shall be used for the bank protection and for final soil amendments elsewhere. 9. No stream banks shall be left exposed (i.e. bare) at the end of the work day. All stream banks shall be covered with matting before the Contractor stops work for the day. Contractor shall temporarily cover any disturbed areas with matting at the end of each work day, only if final stabilization is not completed by the end of the day. In addition, any remaining disturbed areas in the overbank zones shall be protected from sheet flow with silt fence until work continues the next day. 10. After all stream work is complete and approved by County and Engineer/Designer, the Contractor may commence with demobilizing pump -around diversions. 11. Upon completion of all stream restoration activities, all temporary erosion and sediment control measures shall be removed within 30 days. Any concentrated sediment along the erosion and sediment controls measures shall be respread and stabilized with seed/mulch in uplands. 12. Contractor shall notify County and Engineer/Designer upon completion of cleanup activities to arrange a final site inspection. Contractor shall coordinate with County and Engineer/Designer to schedule installation of woody vegetation including trees and shrubs. As the planting window for this vegetation may not fall within the construction window, the planting shall be scheduled at the earliest time possible as shown in specifications or as approved by County and Engineer/Designer. 2.8 PROHIBITION OF NONSTORMWATER DISCHARGES Except as provided in Parts I A 2, 1 C and I E of the Construction General Permit, all discharges covered by the general permit shall be composed entirely of stormwater associated with construction activities. All other discharges including the following are prohibited: • Wastewater from washout of concrete; • Wastewater from the washout and cleanout of stucco, paint, form release oils, curing compounds, and other construction materials; E 2.11 STORMWATER POLLUTION PREVENTION PLAN — INNISFREE STREAM MITIGATION BANK SITE EVALUATION, ASSESSMENT, AND PLANNING • Fuels, oils, or other pollutants used in vehicle and equipment operation and maintenance; Oils, toxic substances, or hazardous substances from spills or other releases; and • Soaps, solvents, or detergents used in equipment and vehicle washing. 2.9 AUTHORIZED NONSTORMWATER DISCHARGES The following nonstormwater discharges from construction activities are authorized by the general permit.

THE SITE IS LOCATED WEST OF BROWNS GAP TURNPIKE (STATE ROUTE 810), WEST OF WALNUT LEVEL ROAD (ROUTE 668), NORTH OF CCC ROAD, AND EAST OF SKYLINE DRIVE. THE SITE CAN BE CHARACTERIZED PREDOMINANTLY AS A CATTLE FARM WITH DENSE STANDS OF MATURE FOREST, PARTICULARLY ALONG EXISTING STREAMS AND DRAINAGES. THE SITE EXHIBITS ROLLING TOPOGRAPHY ON THE EASTERN AND SOUTHERN PORTION OF THE SITE, WITH STEEP MOUNTAINOUS RELIEF ON THE WESTERN AND NORTHERN PORTIONS OF THE PROPERTY. VIRTUALLY ALL STREAM REACHES ONSRE DRAIN FROM NORTHWEST TO SOUTHEAST, FROM THE DRAINAGE DIVIDE OF THE BLUE RIDGE MOUNTAIN RIDGE TOP TOWARDS THE JOY -ES RIVER LOCATED JUST OFFSITE. MOST REACHES ONSITE HAVE EXPERIENCED A LONG HISTORY OF ALTERATION, INCLUDING LOGGING OF THE SURROUNDING WATERSHED, CONVERSION OF FORESTED BUFFER TO FARM AND PASTURELAND, STRAIGHTENING OF CHANNEL ALIGNMENTS FOR FLOOD CONTROL AND MAXIMIZATION OF PASTURELAND, WIDESPREAD CATTLE ACCESS TO STREAM CHANNELS, AND INSTALLATION OF MULTIPLE PONDS AND ROAD CROSSINGS. THESE ALTERATIONS HAVE RESULTED IN WIDESPREAD CHANNEL INSTABILITIES INCLUDING SEVERE EROSION AND INCISION FROM THE SURROUNDING FLOODPLAINS. OVERWIDENINGOF CHANNEL DIMENSIONS AND ASSOCIATED LOSS OF STREAM POWER, UNDERCUTTING OF MATURE TREE ROOTING SYSTEMS, VALLEY WALL CORRECTS, AND LOCALIZED EMBEDDEDNESS OF BENTHIC HABITAT. ALL RESTORATION REACHES EXHUNT SOME DEGREE OF CHANNEL INCISION AND DISCONNECTION FROM THE SURROUNDING FLOODPLAINS, AND PRIMARILY EXHIBIT GEOMORPHOLOGIC CHARACTERITICS OF UNSTABLE B.

THE SITE IS SITUATED NORTH OF CCC ROAD AND WEST OF ROUTE 668. THE PRIMARY GOAL OF THE EROSION AND SEDIMENT CONTROL PLAN IS TO PROTECT THE DOWNSTREAM RECEIVING REACHES AND WATERCOURSES FROM ADDITIONAL EROSION AND SEDIMENT CONTAMINATION. CARE SHALL BE TAKEN TO ENSURE THAT ALL DOWNSTREAM WATERCOURSES REMAIN FREE O SEDIMENT DURING CONSTRUCTION. OTHERS. THESE MEASURES WILL BE CONSTRUCTED PLAN WILL RELY PREDOMINANTLY ON PUMP AROUND DIVERSIONS TO AMOUNT OF SEDIMENT BEING TRANSPORTED DOWNSTREAM INTO UNDISTURBED AREAS. CARE SHALL BE TAKEN TO SCHEDULE THE CONSTRUCTION WHEN RAINFALL IS NOT ANTICIPATED AND BASE FLOW WITHIN THE STREAMS IS RELATIVELY MINOR. ADDITIONALLY, ALL DISTURBED AREAS SHALL BE IMMEDIATELY STABILIZED FOLLOWING GRADING ACTIVITIES, LIMITING THE DISTURBED AREAS BY STABILIZING ONE AREA BEFORE CONSTRUCTION BEGINS ON ANOTHER. THE TOTAL DISTURBED AREA PROPOSED (LOD) IS 9.9 -1-ACRES. THE ALBEMARLE COUNTY INSPECTOR HAS THE AUTHORITY TO ADD CR DELETE EROSION AND SEDIMU CONTROLS AS NEEDED IN THE FIELD AS CONDITIONS WARRANT. PRE -CONSTRUCTION: 1. THE CONTRACTOR SHALL BE RESPONSIBLE FOR DETERMINING THE EXACT LOCATIONS OF ALL EXISTING UTILITIES WITHIN THE PROJECT AREA PRIOR TO CONSTRUCTION OPERATIONS, AND MUST CONTACT MISS UTILITY (811 j PRIOR TO THE COMMENCEMENT OF MY CONSTRUCTION ACTIVITIES. THE CONTRACTOR MUST ARRANGE A PRECONSTRUCTIONMEETING WITH ALBEMARLE COUNTY AND THOMAS JEFFERSON SOIL 8 WATER CONSERVATION DISTRICT. SITE PREPARATION: 1. INSTALL STONE CONSTRUCTION ENTRANCES PER STD. 8 SPEC. 3.02. 2. INSTALL SILT FENCE AND TREE PROTECTION WHERE SHOWN. 3. INSTALL EROSION AND SEDIMENT CONTROL MEASURES ACCORDING TO STANDARDS SET FORTH IN THE VIRGINIA EROSION AND SEDIMENT CONTROL HANDBOOK, THIRD EDITION 1992. THESE MEASURES SHALL BE IMPLEMENTED PRIOR TO THE COMMENCEMENT OF ANY EARTHWORK ACTMTIES ON -SITE. 4. UPON APPROVAL OF COUNTY STAFF, COMMENCE WITH TREE REMOVAL AND CLEARING AND GRUBBING OPERATIONS. TREE REMOVAL, CLEARING, GRUBBING, AND ANY DEMOLITION SHALL BE PERFORMED IN PHASES TO MINIMIZE EARTH DISTURBANCE DURING CONSTRUCTION. 5. CONCURRENT WITH THE TREE REMOVAL AND CLEARING AND GRUBBING OPERATIONS, CONTRACTOR SHALL INSTALL TIMBER MATS, MULCH ACCESS ROAD STABILIZATION, ANDIOR GRAVEL ACCESS ROAD STABILIZATION. INSTALLATION SHALL BE PROGRESSIVELY IN ADVANCE OF HEAVY EQUIPMENT USED TO PLACE THESE PRACTICES SUCH THAT THE WEIGHT OF THE EQUIPMENT IS BORNE BY PREVIOUSLY INSTALLED SECTION OF THE ROAD AS IT IS CONSTRUCTED. 6. INVASIVE PLANT SPECIES WITHIN THE LOD SHALL BE REMOVED ANDIOR CONTROLLED AS DETAILED. Y. IT IS THE INTENT OF THESE PLANS TO AVOID CLEARING TO THE GREATEST EXTENT PRACTICAL. HOWEVER. CLEARING AND GRUBBING OPERATIONS SHALL PROCEED AS NECESSARY TO FACILITATE EARTHWORK ACTIVITIES. EXISTING VEGETATION CALLED OUT TO BE PRESERVED SHALL BE PROTECTED FROM DISTURBANCE AND COMPACTION OF HEAVY EQUIPMENT. ALL ADDITIONAL CLEARED WOODY VEGETATION SHALL BE REMOVED. CHIPPED, STOCKPILED, AND USED FOR ORGANIC MATTER ON -SITE. 8. PROTECT ALL SANITARY SEWER PIPES, MAN HOLES, EXISTING DRY UTILITIES (E.G. ELECTRICAL, GAS, CABLE, PHONE, N. ETC) AND STORM SEWER PIPES CROSSED THROUGHOUT THE PROJECT USING TIMBER MATTING OR APP ROV ED ALTERNATI V E. 9. CONTRACTOR SHALL ONLY GRADE AN AREA THAT CAN BE STABILIZED WITHIN THE SAME DAY. 10.AT COMPLETION OF SITE PREPARATION ALL E8S SITE PREPARATION PROTECTION MEASURES. ACCESS ROADS STAGING AREAS, SHALL BE ESTABLISHED. CHANNEL CONSTRUCTION: 1. CONSTRUCTION ACTIVITIES SHALL BE PERFORMED IN REACH SEGMENTS IN AN EFFORT TO MINIMIZE DISTURBANCE. B a. UPON APPROVAL BY ENGINEEPoDESIGNER AND THE COUNTY, THE CONTRACTOR MAY PROCEED WITH GRADING, STABILIZATION AND RESTORATION ACTIVITIES FOR THE STREAMS. b. WITHIN A RESPECTIVE REACH SEGMENT, INSTREAM WORK SHOULD BE DONE FROM UPSTREAM TO DOWNSTREAM. c. SILT FENCE MAY BE REMOVED BETWEEN CONSTRUCTION ROAD STABILIZATION AND AN AREA OF THE STREAM UNDER CONSTRUCTION PROVIDED TWAT IT IS REPLACED UPON COMPLETION OF CHANNEL OR STREAM BANK WORK DAILY WHERE CONSTRUCTION ROAD STABILIZATION PROVIDES ACCESS TO A STREAM REACH. 2. ALL WORK WITHIN THE STREAM CHANNELS SHALL BE PERFORMED IN THE DRY. APPROVED PUMP AROUND DIVERSION MEASURES (CHECK DAM, PUMP AROUND DIVERSION PUMP WITH DEWATERING BAG) SHALL BE UTILIZED TO ENSURE THAT SEDIMENT LADEN WATER IS NOT DISCHARGED INTO THE STREAM CHANNEL. THE PUMP AROUND DIVERSION SHALL BE OF SUFFICIENT LENGTH TO ENSURE THAT ALL WORK WITHIN THE DAILY WORK ZONE IS PERFORMED IN THE DRY. 3. THE DAILY CONSTRUCTION SEGMENTS SHALL BE DETERMINED BY THE CONTRACTOR BUT THE STREAM WILL BE PERMANENTLY OR TEMPORARILY STABILIZED AND RECONNECTED AT THE END OF EACH WORK DAY. 4. PUMP AROUND DIVERSIONS SHALL NOT BE OPERATED AT NIGHT, UNLESS APPROVED UNDER SEPARATE COVER BY COUNTY. S. CONTRACTOR SHALL SALVAGE STREAM BED SUBSTRATE MATERIAL FROM THE EXISTING CHANNEL. THIS MATERIAL WILL BE USED AS INFILL FOR STREAMBED RE INFORCEMENT AREAS. 6. INSTALLED E8S MEASURES (E.G. TREE PROTECTION, SILT FENCE, SUPER SILT FENCE, AND SAFETY FENCE) TO REMAIN IN PLACE UNTIL FINAL STABILIZATION OF ALL DISTURBED AREAS HAS BEEN ACHIEVED EXCEPT FOR TEMPORARY REMOVAL OF SILT FENCE BETWEEN CONSTRUCTION ROAD STABILIZATION AND STREAMS AS NOTED ABOVE. T. COMMENCE WITH GRADING OF THE NEW STREAM CHANNEL, SECTIONS, PROFILE, AND INSTALLATION OF FREE OF UNSUITABLES. STRIPPED TOPSOIL SHALL BE USED FOR THE BANK PROTECTION AND FOR FINAL SOIL A AMENDMENTS ELSEWHERE. 9. NO STREAM BANKS SHALL BE LEFT EXPOSED (I.E. RARE) AT THE END OF THE WORK DAY. ALL STREAM BANKS SHALL BE COVERED WITH MATTING BEFORE THE CONTRACTOR STOPS WORK FOR THE DAY. CONTRACTOR SHALL TEMPORARILY COVER ANY DISTURBED STREAMBANKS WITH MATTING AT THE END OF EACH WORK DAY, ONLY IF FINAL STABILIZATION IS NOT COMPLETED BY THE END OF THE DAY. IN ADDITION, MY REMAINING DISTURBED AREAS IN THE OVERBANK ZONES SHALL BE PROTECTED FROM SHEET FLOW WITH SILT FENCE UNTIL WORK CONTINUES THE NEXT DAY. 10.AFTER ALL STREAM WORK IS COMPLETE AND APPROVED BY COUNTY AND ENGINEERIDESIGNER. THE CONTRACTOR MAY COMMENCE WITH DEMOBILIZING PUMPAROUND DIVERSIONS. 11.UPON COMPLETION OF ALL STREAM RESTORATION ACTIVITIES, ALL TEMPORARY EROSION AND SEDIMENT CONTROL MEASURES SHALL BE REMOVED WITHIN W DAYS. ANY CONCENTRATED SEDIMENT ALONG THE EROSION AND SEDIMENT CONTROL MEASURES SHALL BE RESPREAD AND STABILIZED WITH SEEDrMULCH IN UPLANDS. 12. CONTRACTOR SHALL NOTIFY COUNTY AND ENGINEEWDESIGNER UPON COMPLETION OF CLEANUPACUJNHES TO ARRANGE A FINAL SITE INSPECTION. CONTRACTOR SHALL COORDINATE WITH COUNTY AND ENGINEERIDESIGNER TO SCHEDULE INSTALLATION OF WOODY VEGETATION INCLUDING TREES AND SHRUBS.
