STORMWA TER RUNOFF NARRATIVE.•
THE STORMWATER RUNOFF FROM THE BORROW AREA DISTURBANCE TEMPORARILY DRAINS TO THE PROPOSED
SEDIMENT TRAP. THE STORMWATER WILL BE TREATED IN THIS MANNER DURING THE TEMPORARY
CONSTRUCTION STATE.
ONCE THE BORROW AREA IS NO LONGER OPERATIONAL, THE UPLAND AREAS AND DISTURBANCES ARE
STABILIZED, AND THE PROJECT CONSTRUCTION IS COMPLETE, THE SEDIMENT TRAP SHALL NO LONGER BE
NECESSARY. ONCE THE ESC INSPECTOR HAS GRANTED APPROVAL TO REMOVE THE SEDIMENT TRAP, THE
TEMPORARY FACILITY SHALL BE FILLED AND GRADED WITH POSITIVE GENTLE SLOPES, PROMOTING SHEET FLOW
RUNOFF WITHOUT CHANNEL/ZED, OR CONCENTRATED FLOW. AT THE CONCLUSION OF THE PROJECT, THERE WILL
BE A NET DECREASE IN IMPERVIOUS AREA AND CONCENTRATED FLOWS. THE PROPOSED FINAL GROUNDCOVER
SHALL BE RESEEDED AND STABILIZED. NUTRIENT CREDITS SHALL BE PURCHASED FOR THE 0.18 LB/YEAR

authority. All undrained pockets and stagnant pools of water resulting from drainage shall be treated as required by the Virginia Department of Health to eliminate breeding places for mosquitoes and other insects.
2. No fill or waste area shall be located either within the flood hazard overlay district except as authorized by section 30.3 of this chapter, or in any stream buffer area as defined by Chapter 17 ofthe Code of Albemarle.
(Amended 10-3-01; 7-3-02)
3. Each fill or waste area shall be onlyfor the disposal of soil or inert materials. The disposal of an other materials in a fill or waste area is prohibited.

cleaned so that no inert materials outside of the vehicle's load -bed can be deposited on a public street.
2. The borrow, fill or waste area and the access roads thereto shall be treated or maintained to prevent dust or debris from blowing or spreading onto adjacent properties or public streets. Depending on the anticipated
P g sP g 1 P P P Pe g Pa
intensity and duration of the activity and the character of the development of adjoining properties, the program authority may require setback fencing and landscaping requirements as deemed appropriate, but which
shall not exceed the requirements of sections 30.4.6, 30.4.7 and 30.4.9 of this chapter.
3. Borrow, fill or waste activity involving industrial -type power equipment shall be limited to the hours of 7:00 a.m. to 9.00 p.m., except in cases of a public emergency declared pursuantto section 2-1003 of the Code of

street because of slides, sinking, or collapse.
5. The placement of fill or waste shall be completed within one year of its commencement, except for reclamation activities and any other activities associated with the final stabilization of the area. The program authority may
extend the date of completion upon the written request of the applicant, demonstrating that factors beyond the control of the applicant prevented the completion within the one-year period. The program authority may
then extend the permit for a period of time that, in its sole discretion, is determined adequate to complete the work.

MITIGATION NOTE:
THERE ARE NO NON -WOODED AREAS WITHIN THE EXISTING STREAM
BUFFER ON -SITE, SO TRADITIONAL MITIGATION PLANTING CAN NOT BE
ACCOMPLISHED. THE PLEASANT GREEN SPECIAL -USE PERMIT
APPLICATION PROPOSES THE FOLLOWING MEASURES TO MITIGATE
IMPACTS TO THE EXISTING STREAM BUFFER AND FILLING IN THE
FLOODPLAIN:
1. REMOVAL OF THE EXISTING DAM IN POWELL'S CREEK. THE
APPLICANT IS PROPOSING TO REMOVE THE CONCRETE DAM THAT
IMPOUNDS WATER IN POWELL'S CREEK (NORTH OF THIS PROJECT).
WITH THE REMOVAL OF THE DAM, THE APPLICANT SHALL RESTORE
THE NATIVE STREAM FLOW PATTERNS. THIS WILL HELP RESTORE THE
RIPARIAN HABITAT THAT HAS BEEN ALTERED DUE TO THE DAM
CONSTRUCTION AND ALLOW AQUATIC LIFE TO TRAVEL UP AND DOWN
THE STREAM BED, RESTORING THE NATURAL PROCESSES
CURRENTLY IMPACTED BY THE DAM.
2. PROVIDE STREAM BANK STABILIZATION WITH ARMORING TO PROTECT
THOSE AREAS ALONG POWELL'S CREEK ON THE PROPERTY WITH
EXTREME EROSION ISSUES.
3. RESTORATION IN AREAS ALONG POWELL'S CREEK WHERE TREE
COVER IS SPARSE. PLANTINGS THROUGHOUT THE POWELL'S CREEK
STREAM BUFFER WILL MITIGATE THE IMPACTS FROM THE
CONNECTOR ROAD CONSTRUCTION.

SEQUENCE OF CONSTRUCTION:
1. CONTRACTOR SHALL NOTIFY THE ALBEMARLE COUNTY COMMUNITY DEVELOPMENT ENGINEERING DEPARTMENT TO SCHEDULE A PRE -CONSTRUCTION
MEETING.
2. PRIOR TO DISTURBANCES, THE LIMITS OF DISTURBANCE (2.36 cc) SHALL BE FLAGGED AND TREE PROTECTION FENCING SHALL BE INSTALLED.
J. NO EROSION CONTROL MEASURES MAY BE REMOVED DURING THE CONSTRUCTION PROCESS WITHOUT THE APPROVAL FROM THE INSPECTOR ON
THE PROJECT.
4. INSTALLATION OF THE PROPOSED CONSTRUCTION ENTRANCE SHALL OCCUR NEXT. THE CONTRACTOR SHALL APPLY CONSTRUCTION ROAD
STABILIZATION AS NEEDED TO THE CONSTRUCTION ENTRANCE AND CONTRACTOR PARKING / STAGING AREA. CONSTRUCTION ENTRANCE TO BE
INSTALLED WHERE CONSTRUCTION VEHICLE ROUTES INTERSECT PAVED PUBLIC ROADS, PROVISIONS SHALL BE MADE TO MINIMIZE THE TRANSPORT
OF SEDIMENT BY (VEHICULAR) TRACKING ONTO THE PAVED SURFACE. WHERE SEDIMENT IS TRANSPORTED ONTO A PUBLIC ROAD SURFACE, THE
ROAD SHALL BE CLEANED THOROUGHLY AT THE END OF EACH DAY. SEDIMENT SHALL BE REMOVED FROM THE ROADS BY SHOVELING OR
SWEEPING AND TRANSPORTING TO A SEDIMENT CONTROL DISPOSAL AREA. STREET WASHING SHALL BE ALLOWED ONLY AFTER SEDIMENT IS
REMOVED IN THIS MANNER.
5. THE INITIAL ESC CONSTRUCTION MEASURES, AS SHOWN ON THE EROSION & SEDIMENT CONTROL PLAN, SHALL BE INSTALLED NEXT. THE
CONTRACTOR SHALL BEGIN BY INSTALLING THE PERIMETER SILT FENCE AND TREE PROTECTION. PERIMETER MEASURES INTENDED TO TRAP
SEDIMENT SHALL BE CONSTRUCTED AS A FIRST STEP WITH ANY LAND DISTURBANCE ACTIVITY AND SHALL BE MADE FUNCTIONAL BEFORE
UPSLOPE LAND DISTURBANCE TAKES PLACE. NO WORK SHALL BE COMPLETED UNTIL PERIMETER CONTROLS ARE IN PLACE.
6. ONCE THE PERIMETER EROSION CONTROL SILT FENCE AND TREE PROTECTION HAVE BEEN INSTALLED, AND THE COUNTY INSPECTOR HAS
APPROVED THESE MEASURES, LIGHT CLEARING AND LAND DISTURBANCE MAY BEGIN FOR THE SEDIMENT TRAP. THE CONTRACTOR SHALL INSTALL
ANY REMAINING EROSION CONTROL ITEMS AS SHOWN ON THE EROSION CONTROL PLAN. TEMPORARY SEEDING, PERMANENT SEEDING AND DUST
CONTROL SHALL BE IMPLEMENTED AS REQUIRED.
7. ONCE ALL THE EROSION CONTROL ITEMS HAVE BEEN INSTALLED & ARE OPERATIONAL, DRAINAGE IS PROPERLY CONVEYED TO THESE MEASURES,
