THE PROJECT ALSO INVOLVES THE INSTALLATION OF TWO BIO- RETENTION BASINS. THE TWO PROPOSED AND FOUR EXISTING BMPS HAVE BEEN DESIGNED TO COLLECTIVELY ADDRESS THE WATER QUALITY AND QUANTITY ASSOCIATED WITH THIS RESIDENTIAL DEVELOPMENT, THE FUTURE APARTMENT SITE, AND A PORTION OF A FUTURE RESIDENTIAL DEVELOPMENT EAST OF THIS PROJECT. THE DISTURBED AREA ASSOCIATED WITH THIS PROJECT IS APPROXIMATELY 51 ACRES. THE EXISTING SITE IS MOSTLY FORESTED. THE MAJORITY OF THE SITE SLOPES NORTHWEST TO RIVANNA RIVER. THE SITE CONTAINS WATERS OF THE U.S. THAT SHALL REMAIN UNDISTURBED EXCEPT FOR THE PERMITTED AREAS TO BE IMPACTED. GRAVITY SANITARY SEWER AND A 12" WATERLINE ARE AVAILABLE FOR CONNECTION AS PART OF THE NORTH POINTE SECTION ONE PROJECT. EACH WILL BE EXTENDED TO SERVICE THIS PROJECT. ADJACENT AREAS THE SITE IS BORDERED BY GRACE BAPTIST CHURCH AND FURTURE DEVELOPMENT TO THE WEST, PRITCHETT DRIVE (VA 785) TO THE SOUTH, AND FORESTED PARCELS TO THE EAST. OFFSITE AREAS THERE IS NO OFFSITE WORK PROPOSED WITH THIS PROJECT. SOILS THE SITE IS CHARACTERIZED BY SANDY, LEAN CLAY (CL) AND SILTY, LEAN SAND (SM). CRITICAL AREAS SENSITIVE AREAS INCLUDE WETLANDS AND WATERS OF TEIE U.S., CONTRACTOR MUST CONTROL EROSION AND SEDIMENTATION FROM LAND DISTURBING ACTIVITIES AND PREVENT TEEM FROM ENTERING WATERWAYS. THIS SITE IS SET UP TO DRAIN TO TWO SEDIMENT TRAPS AND A SEDIMENT BASIN WHICH WILL BE MAINTAINED UNTIL THE SITE IS STABILIZED. THE SITE CONTAINS STEEP SLOPES THROUGHOUT THE DISTURBED AREAS. THESE DISTURBED AREAS WILL NEED TO BE SEEDED AND STABILIZATION ACHIEVED TO PREVENT EROSION FROM OCCURRING AS THE WORK PROGRESSES. THE CONTRACTOR SHOULD ALSO TAKE CARE TO KEEP CONSTRUCTION ENTRANCES IN GOOD WORKING CONDITION IN ORDER TO NOT TRACK MUD ONTO EXISTING ROADWAYS. EROSION AND SEDIMENT CONTROL MEASURES - PHASE I 1 -ALL EROSION AND SEDIMENT CONTROL MEASURES MUST BE INSTALLED, MAINTAINED AND REMOVED IN ACCORDANCE WITH THE CRITERIA AND GUIDELINES CONTAINED IN THE CURRENT EDITION OF THE VIRGINIA EROSION & SEDIMENT CONTROL HANDBOOK. 2 - PERMANENT OR TEMPORARY SOIL STABILIZATION SHALL BE APPLIED TO DENUDED 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 (UNDISTURBED) FOR LONGER THAN 14 DAYS. PERMANENT STABILIZATION SHALL BE APPLIED TO AREAS THAT ARE TO BE LEFT DORMANT FOR MORE THAN ONE YEAR. 3 - WHERE CONSTRUCTION VEHICLE ACCESS ROUTES INTERSECT PAVED PUBLIC ROAD S, 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 TRANSPORTED TO A SEDIMENT CONTROL DISPOSAL AREA. STREET WASHING SHALL BE ALLOWED ONLY AFTER SEDIMENT IS REMOVED IN THIS MANNER 4 - UNDERGROUND UTILITY LINES SHALL BE INSTALLED IN ACCORDANCE WITH THE FOLLOWING STANDARDS IN ADDITION TO OTHER APPLICABLE 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 FROM DEWATERING OPERATIONS SHALL BE FILTERED OR PASSED THROUGH AN APPROVED SEDIMENT TRAPPING DEVICE, OR BOTH, AND DISCHARGED IN A MANNER THAT DOES NOT ADVERSELY AFFECT FLOWING STREAMS OR OFF -SITE PROPERTY. D - RESTABILIZATION SHALL BE ACCOMPLISHED IN ACCORDANCE WITH THESE REGULATIONS. E - APPLICABLE SAFETY REGULATIONS SHALL BE COMPLIED WITH. 5 - ADDITIONAL EROSION CONTROL MEASURES MAY BE REQUIRED BY ENVIRONMENTAL ENGINEERING IF WARRANTED BY FIELD CONDITIONS. 6 - THE TEMPORARY SEDIMENT TRAPS OR SEDIMENT BASIN SHALL NOT BE REMOVED UNTIL APPROVED BY ENVIRONMENTAL ENGINEERING. 7 - A VD OT LAND USE PERMIT IS REQUIRED FOR THIS PROJECT PRIOR TO ISSUANCE OF A LAND DISTURBANCE PERMIT. 8 - AT THE TIME OF THE PRE -CONSTRUCTION MEETING, TWO STANDARD SIGNS MUST BE INSTALLED ON EACH SIDE OF THE CONSTRUCTION ACCESS.

Specific Facilities may require additional measures not discussed here. A schedule of recommended maintenance for bioretention areas is given in Table 3.11-5. The table gives general guidance regarding methods, frequency, and time of year for maintenance. Planting Soil Urban plant communities tend to become very acidic due to precipitation as well as the influences of storm water runoff. For this reason, it is recommended that the application of alkaline, such as limestone, be considered once to twice a year. Testing ofthepH of the organic layer and soil, should precede the limestone application to determine the amount of limestone required. Soil testing should be conducted annually so that the accumulation of toxins and heavy metals can be detected or prevented. Over a period of time, heavy metals and other toxic substances will tend to accumulate in the soil and the plants. Data from other environs such as forest buffers and grass swales suggest accumulation of toxins and heavy metals within five years ofinstallation. However, there is no methodology to estimate the level oftoxic materials in the bioretention areas since runoff, soil, and plant characteristics will vary from site to site. As the toxic substances accumulate, the plant biologic functions maybecome impaired, and the plant „dia5 experience dwarfed growth followed by mortality. The biota within the soil can also become void and the natural soil chemistry may be altered. The preventative measures would include the removal ofthe contaminated soil. In some cases, removal and disposal of the entire soil base as well as the plant material may be required. Mulch Bioretention areas should be mulched once the planting of trees and shrubs has occurred. Any ground cover specified as plugs may be installed once the area has been mulched. Ground cover established by seeding and/or consisting of grass should not be covered with mulch. GRAPHIC SCALE 20 40 ( IN FEET ) 1 inch = 20 ft. LEGEND FINISHED GRADE AT C/L — — — — — — — — — EXIST.
