MANAGEMENT STRATEGY AND SEQUENCE OF CONSTRUCTION THE FOLLOWING ARE THE PROPOSED MANAGEMENT STRATEGIES AND DETAILED SEQUENCE OF CONSTRUCTION: PHASE 1 1. INSTALL TEMPORARY CONSTRUCTION ENTRANCE. 2. INSTALL ALL EROSION CONTROL MEASURES INCLUDING TEMPORARY DIVERISONS AND SILT FENCE 3. CONTACT THE ENGINEER AND ALBEMARLE COUNTY FOR INSPECTION AND APPROVAL OF ALL E&S CONTROL MEASURES. 4. UPON APPROVAL OF ALL E&S CONTROL MEASURES, BEGIN WHOLESALE CLEARING, GRADING AND STOCKPILING. 5. PROTECT SOIL STOCKPILES WITH SILT FENCING AND TEMPORARY SEEDING AS NECESSARY. 6. MAINTAIN ALL E&S CONTROL MEASURES. PHASE 2 1. CONSTRUCT SITE IMPROVEMENTS AS SHOWN ON THE PLAN. INCLUDING GRADING AND POOL CONSTRUCTION. 2. ESTABLISH AND MAINTAIN PERMANENT STABILIZATION FEATURES, WHICH INCLUDES THE ESTABLISHMENT OF A PERMANENT VEGETATIVE COVER OVER THE ENTIRE DISTURBED AREA. 3. PLANT VEGETATED BUFFER AS SHOWN ON LANDSCAPING PLAN. 4. UPON STABILIZATION OF SITE, REMOVE SILT FENCE AND OTHER E&S ITEMS. EROSION & SEDIMENT CONTROLS UNLESS OTHERWISE INDICATED, ALL EROSION AND SEDIMENT CONTROL PRACTICES WILL BE CONSTRUCTED AND MAINTAINED ACCORDING TO THE MINIMUM STANDARDS AND SPECIFICATIONS AS SET FORTH IN THE VIRGINIA EROSION AND SEDIMENT CONTROL HANDBOOK, LATEST EDITION. THE MINIMUM STANDARDS OF THE VIRGINIA EROSION AND SEDIMENT CONTROL REGULATIONS SHALL BE ADHERED TO UNLESS OTHERWISE WAIVED OR APPROVED BY VARIANCE. TEMPORARY CONSTRUCTION ENTRANCE (CE) - 3.02 A STONE PAD WILL BE CONSTRUCTED AT THE ENTRANCE THE SITE TO PROVIDE A MEANS OF REMOVING SEDIMENT FROM THE TIRES OF CONSTRUCTION VEHICLES LEAVING THE WORK SITE. THE CONTRACTOR SHALL REMOVE ANY MUD FROM THE EXISTING ROAD SURFACE BY MEANS OF SWEEPING AND SHOVELING. WIRE SILT FENCE (WSF) - 3.05 WIRE SILT FENCING WILL BE INSTALLED AS A FIRST STEP IN CONSTRUCTION ACTIVITIES. LOCATION AND DETAILS ARE SHOWN ON THE PLANS. DIVERSION (DV) - 3.12 A PERMANENT CHANNEL WITH A RIDGE ON THE LOWER SIDE CONSTRUCTED ACROSS A SLOPE TO REDUCE SLOPE LENGTH AND INTERCEPT AND DIVERT STORMWATER RUNOFF TO A STABILIZED OUTLET AT NON -EROSIVE VELOCITIES STD. AND SPEC. 3.12. DUST CONTROL (DC) - 3.39 DUST CONTROL MEASURES IN ACCORDANCE WITH STANDARD AND SPECIFICATION 3.39 SHALL BE IMPLEMENTED ONSITE TO PREVENT AIRBORNE MOVEMENT OF DUST. MEASURES INCLUDE IRRIGATION, MULCHING OR OTHER MEASURES AS OUTLINED IN THE SPECIFICATIONS. TEMPORARY SEEDING (TS) - 3.31 TEMPORARY SEEDING SHALL BE APPLIED TO ALL DENUDED AREAS WITHIN SEVEN (7) DAYS TO DENUDED AREAS THAT MAY OR MAY NOT BE AT FINAL GRADE BUT WILL REMAIN DORMANT (UNDISTURBED) FOR LONGER THAN 14 DAYS. TEMPORARY SEEDING SHALL BE APPLIED IN CONFORMANCE WITH STD AND SPEC. 3.31. PAVED WASH RACK: ( Albemarle County Design standards) THE COUNTY REQUIRES PAVED WASH RACKS ON CONSTRUCTION SITES, THIS CAN BE WAIVED IN RURAL AREAS ON SMALL JOBS WHERE WATER IS NOT AVAILABLE AND A STONE CONSTRUCTION ENTRANCE PROVES EFFECTIVE. PERMANENT STABILIZATION PERMANENT SEEDING (PS) - 3.32 ALL DITCHES AND ADJACENT AREAS WITHIN 15 FT OF THE EDGE OF THE DITCHES SHALL BE SEEDED IN CONFORMANCE WITH STD. AND SPEC. 3.32. PERMANENT SEEDING SHALL BE APPLIED TO AREAS DELINEATED ON THESE PLANS WITHIN SEVEN (7) DAYS AFTER FINAL GRADE IS REACHED ON ANY PORTION OF THE SITE. PERMANENT SEEDING STABILIZES DISTURBED AREAS AND ENHANCES THE BEAUTY OF THE SITE. MULCHING (MU) - 3.35 APPLICATION OF PLANT RESIDUES OR OTHER SUITABLE MATERIALS TO THE SOIL SURFACE TO PREVENT EROSION AND FOSTER THE GROWTH OF VEGETATION. ORGANIC MULCHES (STRAW) HAVE BEEN FOUND TO BE THE MOST EFFECTIVE. STORMWATER MANAGEMENT: THIS PROJECT COMPLIES WITH THE WATER QUANTITY REQUIREMENTS OF 9VAC25-870-66.D BECAUSE THE RUNOFF FROM THE ENTIRE SITE WILL BE SHEET FLOW . THE PROPOSED GRADING DOES NOT CONCENTRATE BUT RATHER DISPERSE RUNOFF, THUS POST-DEVELPED RUNOFF IS SHEET FLOW. ALL RUNOFF FROM THE NEW IMPERVIOUS AREAS WILL BE ROUTED TO A VEGETATED BUFFER. THIS VEGETATED BUFFER WILL SERVCE AS A VEGETATED FILTER STRIP WITH A GRAVEL DIAPRHAGM AT THE TOP AND A PERMEABLE BERM AT THE TOE. THIS WILL REDUCE THE VELOCITY AND VOLUME OF THE SHEETFLOW RUNOFF AND WILL EFFECTIVELY PROTECT DOWNSTREAM PROPERTIES FROM EROSION. SINCE THE INCREASED VOLUME OF SHEETFLOW RUNOFF WILL NOT CAUSE ADVERSE IMPACTS DOWNSTREAM, THIS PROJECT SATISFIES WATER QUANTITY REQUIREMENTS OF 9VAC25-870-66.D. THIS PROJECT COMPLIES WITH THE WATER QUALITY REQUIREMENTS OF 9VAC25-870-65 BY ACHIEVING NUTRIENT TREATMENT SET FORTH IN THE VRRM RE -DEVELOPMENT SPREADSHEET. THE TOTAL PHOSPHORUS LOAD REDUCTION REQUIRED IS 0.25 LBS/YR. TO ACHIEVE THIS REDUCTION, RUNOFF FROM THE DISTURBED AREA IS ROUTED TO THE VEGETATED BUFFER/FILTER STRIP. A TOTAL OF 0.56 AC MANAGED TURF AND 0.11 ACRES NEW IMPERVIOUS WILL BE TREATED BY THE VEGETATED FILTER STRIP. THE PHOSPHOROUS REDUCTION ACHIEVED BY THIS MEASURE EQUALS 0.25 LBS/YR. THUS, THE FILTER STRIP SATISFIES THE VRRM WATER QUALITY REQUIREMENTS OF 9VAC25-870-65. GENERAL NOTES 1.

MINIMUM STANDARDS (MS): All applicable Virginia Erosion and Sediment Control Regulations and Minimum Standards shall be adhered to during all phases of construction. These include, but are not limited to the following: 1. STABILIZATION OF DENUDED AREAS: Permanent or temporary soil stabilization shall be applied to bare areas within seven days after final grade is reached on any portion of the site. Temporary soil stabilization shall be applied within seven days to denuded areas that may not be at final grade but will remain dormant for longer than 14 days. Permanent stabilization shall be applied to areas that are to be left dormant for moer than one year. 2. STABILIZATION OF SOIL STOCKPILES: During construction of the project, soil stockpiles shall be stabilized or protected with sediment trapping measures. The applicant is responsible for temporary protection and permanent stabilization of all soil stockpiles on site as well as soil intentionally transported from the project site. 3. PERMANENT VEGETATIVE COVER A permanent vegetative cover shall be established on denuded areas not otherwise permanently stabilized. Permanent vegetation shall not be considered established until a ground cover is achieve that, in the opinion of the city Inspector, is uniform and mature enough to survive to inhibit erosion. 4. TIMING & STABILIZATION OF SILT TRAPPING MEASURES: Sediment basins and traps, perimeter dikes, sediment barriers and other measures intended to trap sediment shall be constructed as a first step in any land disturbing activity and shall be made functional before upslope land disturbance takes place. 5. STABILIZATION OF EARTHEN STRUCTURES: Stabilization measures shall be applied to earthen structures such as dams, dikes and diversions immediately after installation. 6. SEDIMENT TRAPS AND BASINS: A sediment basin shall control surface runoff from disturbed areas that is comprised of flow from drainage areas greater than or equal to three acres. The sediment basin shall be designed and constructed to accommodate the anticipated sediment loading for the land disturbing activity. The outfall device or system device shall take into account the total drainage area flowing through the disturbed area to be served by the basin. 7. CUT AND FILL SLOPES: Cut and fill slopes shall be designed and constructed in a manner that will minimize erosion. Slopes that are found to be eroding excessively within one year of permanent stabilization shall be provided with additional slope stabilizing measures until the problem is corrected. & CONCENTRATED RUN-OFF DOWN CUT OR FILL SLOPES: Concentrated runoff shall not flow down cut or fill slopes unless contained within an adequate temporary or permanent channel, flume, or slope drain structure. 9. WATER SEEPS FROM A SLOPE FACE: Whenever water seeps from a slope face, adequate drainage or other protection shall be provided. 10. STORM SEWER INLET PROTECTION: All storm sewer inlets that are made operable during construction shall be protected so that sediment -laden water cannot enter the conveyance system without first being filtered or otherwise treated to remove sediment. 11. STABILIZATION OF OUTLETS: Before newly constructed stormwater conveyance channels are made operational, adequate outlet protection and any required temporary or permanent channel lining shall be installed in both the conveyance channel and receiving channel. 12. WORK IN LIVE WATERCOURSES: When work in a live watercourse is performed, precautions shall be taken to minimize encroachment, control sediment transport and stabilize the work area to the greatest extent possible during construction. Nonerodible material shall be used for the construction of causeways and cofferdams. Earthen fill may be used for these structures if armored by nonerodible cover materials. 13. CROSSING A LIVE WATERCOURSE: When a live watercourse must be crossed by construction vehicles more than twice in any six month period, a temporary stream crossing constructed of nonerodible materials shall be provided. 14. APPLICABLE REGULATIONS: All applicable federal, state and local regulations pertaining to working in or crossing live watercourses shall be met. 15. STABILIZATION OF BED AND BANKS The bed and banks of a watercourse shall be stabilized immediately after work in the watercourse is completed. 16. UNDERGROUND UTILITIES: Underground utilities shall be installed in accordance with the following standards in addition to other criteria: a.No more than 500 linear feet of trench may be opened at one time. b.Excavated material shall be placed on the uphill side of trenches c. Effluent for dewatering operations shall be filtered or passed through approved sediment trapping device, or both, and discharged in a manner that does not adversely affect flowing streams or offsite property. d.Material used for backfilling trenches shall be properly compacted in order to minimize erosion and promote stabilization. e. Restabilization shall be accomplished in accordance with these regulations. f. Applicable safety regulations shall be complied with. 17. CONSTRUCTION ACCESS ROUTES: Where construction vehicle access routes intersect paved public roads, provisions shall be made to minimize the transport of sediment by vehicular tracking onto paved surfaces. Where sediment is transported on to a public road surface, the road shall be cleaned thoroughly at the end of each day. Sediment shall be removed by shoveling or sweeping and transported to a sediment control disposal area. Street washing shall be allowed only after sediment is removed in this manner. This provision shall apply to individual lots as well as to larger land disturbing activities. 18. TEMPORARY E&S CONTROL MEASURE REMOVAL: All temporary erosion and sediment control measures shall be removed within 30 days after final site stabilization or after temporary measures are no longer needed, unless otherwise authorized by the local program authority. Trapped sediment and the disturbed soil areas resulting from the disposition of temporary measures shall be permanently stabilized to prevent further erosion and sediment. 19. ADEQUACY OF RECEIVING CHANNELS: Properties and waterways downstream from the development site shall be protected from sediment deposition, erosion and damage, due to increases in volume, velocity and peak flow rates of stormwater runoff for the stated frequency storm of 24-hour duration.

Construction Sequence for Vegetated Filter Strips Vegetated Filter Strips can be within the limits of disturbance during construction- The following procedures should be followed during construction: • Before site work begins, Vegetated Filter Strip boundaries should be clearly marked. • Only vehicular traffic used for filter strip construction should be allowed within 10 feet of the Vegetated Filter Strip boundary (City of Portland, 2004). • If existing topsoil is stripped during grading, it shall be stockpiled for later use- • Construction runoff should be directed away from the proposed filter strip site using appropriate erosion control measures and a diversion dike or other measure. • Construction of the gravel diaphragm or ELS PR not commence until the contributing drainage area has been stabilized and perimeter E&S controls have been removed and cleaned out. • Vegetated Filter Strips require light grading to achieve desired elevations and slopes. This should be done with tracked vehicles to prevent compaction. Topsoil and or compost amendments should be incorporated evenly across the filter strip area, stabilized with seed, and protected by biodegradable erosion control matting or blankets. • Stormwater should not be diverted into the Filter Strip until the turf cover is dense and well established - TABLE 3.31-C TEMPORARY SEEDING PLANT MATERIALS, SEEDING RATES, AND DATES N Ce w SEEDING RATE NORTH' SOUTH" PLANT 3!1 Sll 8/I5 2/I5 5/1 9/1 SPECIES CHARACTERISTICS Acre 1000 ft,W to to to to tar4/30 1I15 Il/I 4/30 9/1 Il/IS OATS 3 bu.
