PROJECT DESCRIPTION

THE PURPOSE OF THIS PROJECT IS TO INSTALL PAVEMENT AND FENCING TO PROVIDE A MULTI-USE SPORTS COURT AREA WITH ACCESS VIA SIDEWALK. THE PROJECT CONSISTS OF REMOVING PORTIONS OF AN EXISTING GRAVEL AREA AND AN EXISTING ROPE AND REBAR FENCE. THE LIMITS OF DISTURBANCE FOR THIS PROJECT IS APPROXIMATELY 0.36 AC. THERE WILL AN OVERALL DECREASE IN IMPERVIOUS LANDCOVER, WHICH WILL RESULT IN AN INCREASE TO PERVIOUS LANDS (IMPERVIOUS TO MANAGED TURF).

EXISTING SITE CONDITIONS

THE PROJECT IS LOCATED ON A PORTION OF THE PROPERTY OWNED AND OPERATED BY GERMANNA COMMUNITY COLLEGE AT 10000 GERMANNA POINT DRIVE, FREDERICKSBURG, VA 22408. THE COORDINATES OF THE LAND DISTURBANCE ARE 38°13'58" N, 77°29'34" W. THE PROJECT SITE IS GRAVEL / MANAGED TURF WITH SHALLOW SLOPES. AN EXISTING FIRE ACCESS ROAD IS LOCATED WITHIN THE PROJECT AREA. THE PROJECT AREA DRAINS TO THE WEST TO AN EXISTING STORM SEWER SYSTEM WHICH LEADS TO A RETENTION BASIN THAT IS ULTIMATELY DISCHARGED TO AN UNNAMED TRIBUTARY OF MASSAPONAX CREEK. UNDERGROUND ELECTRIC IS KNOWN TO BE WITHIN THE WORK AREA. THE CONTRACTOR SHALL BE RESPONSIBLE FOR CONFIRMING THE LOCATION OF ANY UTILITIES WITH MISS UTILITY PRIOR TO COMMENCING LAND DISTURBING ACTIVITIES. GCC WILL PROCURE A THIRD-PARTY UTILITY LOCATOR TO MARK ONSITE UTILITIES WITHIN THE

PROJECT AREA, ESPECIALLY THOSE NOT IN COUNTY RECORDS.

NOTE: FOR DEMONSTRATION OF COMPLIANCE WITH MINIMUM STANDARD 19, SEE PART M. BELOW

19. Properties and waterways downstream from development sites shall be protected from sediment deposition, erosion and damage due to increases in volume, velocity and peak flow rate of stormwater runoff for the stated frequency storm of 24-hour duration in accordance with the following standards and criteria. Stream restoration and relocation projects that incorporate natural channel design concepts are not man-made channels and shall be exempt from any flow rate capacity and velocity requirements for natural or man-made channels:

a. Concentrated stormwater runoff leaving a development site shall be discharged directly into an adequate natural or man-made receiving channel, pipe or storm sewer system. For those sites where runoff is discharged into a pipe or pipe system, downstream stability analyses at the outfall of the pipe or pipe system shall be performed.

b. Adequacy of all channels and pipes shall be verified in the following manner:

(1) The applicant shall demonstrate that the total drainage area to the point of analysis within the channel is 100 times greater than the contributing drainage area of the project in question; or

(2) (a) Natural channels shall be analyzed by the use of a two-year storm to verify that stormwater will not overtop channel banks nor cause erosion of channel bed or banks;

(b) All previously constructed man-made channels shall be analyzed by the use of a 10-year storm to verify that stormwater will not overtop its banks and by the use of a two-year storm to demonstrate that stormwater will not cause erosion of channel bed or banks; and

(c) Pipes and storm sewer systems shall be analyzed by the use of a 10-year storm to verify that stormwater will be contained within the pipe or system.

c. If existing natural receiving channels or previously constructed man-made channels or pipes are not adequate, the applicant shall:

(1) Improve the channels to a condition where a 10-year storm will not overtop the banks and a two-year storm will not cause erosion to the channel, the bed, or the banks;

(2) Improve the pipe or pipe system to a condition where the 10-year storm is contained within the appurtenances;

(3) Develop a site design that will not cause the pre-development peak runoff rate from a two-year storm to increase when runoff outfalls into a natural channel or will not cause the pre-development peak runoff rate from a 10-year storm to increase when runoff outfalls into a man-made channel; or

(4) Provide a combination of channel improvement, stormwater detention or other measures which is satisfactory to the VESCP authority to prevent downstream erosion.

d. The applicant shall provide evidence of permission to make the improvements.

e. All hydrologic analyses shall be based on the existing watershed characteristics and the ultimate development condition of the subject project.

f. If the applicant chooses an option that includes stormwater detention, he shall obtain approval from the VESCP of a plan for maintenance of the detention facilities. The plan shall set forth the maintenance requirements of the facility and the person responsible for performing the maintenance.

g. Outfall from a detention facility shall be discharged to a receiving channel, and energy dissipators shall be placed at the outfall of all detention facilities as necessary to provide a stabilized transition from the facility to the receiving channel.

h. All on-site channels must be verified to be adequate.

i. Increased volumes of sheet flows that may cause erosion or sedimentation on adjacent property shall be diverted to a stable outlet, adequate channel, pipe or pipe system, or to a detention facility.

j. In applying these stormwater management criteria, individual lots or parcels in a residential, commercial or industrial development shall not be considered to be separate development projects. Instead, the development, as a whole, shall be considered to be a single development project.

Hydrologic parameters that reflect the ultimate development condition shall be used in all engineering calculations.

k. All measures used to protect properties and waterways shall be employed in a manner which minimizes impacts on the physical, chemical and biological integrity of rivers, streams and other waters of the state.

l. Any plan approved prior to July 1, 2014, that provides for stormwater management that addresses any flow rate capacity and velocity requirements for natural or man-made channels shall satisfy the flow rate capacity and velocity requirements for natural or man-made channels if the practices are designed to (i) detain the water quality volume and to release it over 48 hours; (ii) detain and release over a 24-hour period the expected rainfall resulting from the one year, 24-hour storm; and (iii) reduce the allowable peak flow rate resulting from the 1.5, 2, and 10-year, 24-hour storms to a level that is less than or equal to the peak flow rate from the site assuming it was in a good forested condition, achieved through multiplication of the forested peak flow rate by a reduction factor that is equal to the runoff volume from the site when it was in a good forested condition divided by the runoff volume from the site in its proposed condition, and shall be exempt from any flow rate capacity and velocity requirements for natural or man-made channels as defined in any regulations promulgated pursuant to § 62.1-44.15:54 or 62.1-44.15:65 of the Act.

m. For plans approved on and after July 1, 2014, the flow rate capacity and velocity requirements of § 62.1-44.15:52 A of the Act and this subsection shall be satisfied by compliance with water quantity requirements in the Stormwater Management Act (§ 62.1-44.15:24 et seq. of the Code of Virginia) and attendant regulations, unless such land-disturbing activities (i) are in accordance with provisions for time limits on applicability of approved design criteria in 9VAC25-870-47 or grandfathering in 9VAC25-870-48 of the Virginia Stormwater Management Program (VSMP) Regulation, in which case the flow rate capacity and velocity requirements of § 62.1-44.15:52 A of the Act shall apply, or (ii) are exempt pursuant to § 62.1-44.15:34 C 7 of the Act.

RESPONSE: THESE PLANS ARE IN ACCORDANCE WITH THE REQUIREMENTS OF § 62.1-44.15:52 A, 9VAC25-870-66, AND THE VCCS AS&S -

SEE SHEET 10 FOR STORMWATER MANAGEMENT INFORMATION.

n. Compliance with the water quantity minimum standards set out in 9VAC25-870-66 of the Virginia Stormwater Management Program (VSMP) Regulation shall be deemed to satisfy the requirements of this subdivision 19.

FILTREXX® SILT SOXX™

NOTES:

1. COMPOST FILTER SOCKS (SILT SOCKS) SHOULD BE USED IN SENSITIVE AREAS (E.G. WETLANDS, STREAM

CROSSINGS) OR OTHER AREAS IN WHICH GROUND DISTURBANCE SHOULD BE MINIMIZED.

2. FILTER MEDIA INSIDE AND AS NECESSARY UP SLOPE OF FILTER SOCK TO BE FILTREXX MEDIA OR APPROVED

EQUAL.

3. STAKES SHOULD BE INSTALLED THROUGH THE MIDDLE OF SOCKS, 10' APART.

4. STAKE SIZE: 2'x2'x36"

5. STAKES DRIVEN AT DEPTH OF 12" FOR SAND AND SILT LOAM SOILS AND 8" FOR CLAY SOILS, WITH A MINIMUM

OF 3" EXPOSED ABOVE SOCK.

6. OVERLAPPING SECTION FROM CONNECTION SHALL BE AT LEAST 18".

7. INSTALLATION OF THE SOCK IS TO BE EITHER ENTRENCHED (MAXIMUM OF 8-FOOT SPACING WHEN PLACED IN 4-INCH TRENCH) OR NOT ENTRENCHED (4-FOOT SPACING BETWEEN STAKES.) SOCK SHOULD NOT BE

ENTRENCHED WITHIN DESIGNATED WETLANDS.

8. ON LOCATIONS WERE GREATER THAN A 200-FOOT LONG SECTION OF GROUND IS TO BE TREATED WITH A COMPOST SOCK, THE SOCK LENGTHS SHOULD BE SLEEVED. AFTER ONE SOCK SECTION (200 FEET) IS FILLED AND KNOTTED OR ZIP TIED, THE SECOND SOCK SECTION SHALL BE PULLED OVER THE FIRST 1-2 FEET AND "SLEEVED", CREATING AN OVERLAP. ONCE OVERLAPPED, THE SECOND SECTION IS FILLED WITH COMPOST STARTING AT THE SLEEVED AREA. TO CREATE A SEAMLESS APPEARANCE, THE SOCKS MAY BE STAKED AT THE OVERLAPPED AREA (WHERE THE SLEEVE IS) TO KEEP THE SECTIONS TOGETHER. SLEEVING AT THE JOINTS IS NECESSARY BECAUSE IT REDUCES THE OPPORTUNITY FOR WATER TO PENETRATE THE JOINTS

WHEN INSTALLED IN THE FIELD.

9. CAN BE SEEDED AT THE TIME OF INSTALLATION IF PERIMETER CONTROL IS TO BE LEFT AS A PERMANENT

FILTER. ENGINEER WILL SPECIFY SEEDING REQUIREMENTS.

MAINTENANCE NOTES:

1. THE COMPOST (SILT) SOCK MUST BE REPLACED IF CLOGGED OR TORN. IF CLOGGING BECOMES EXCESSIVE, THE SOCK MAY NEED TO BE REPLACED WITH A LARGER DIAMETER OR A DIFFERENT

MEASURE.

2. SEDIMENT SHOULD BE REMOVED WHEN ACCUMULATIONS HAVE REACHED 12 THE ABOVE GROUND HEIGHT

OF THE FILTER SOCK.

3. THE COMPOST (SILT) SOCK SHALL BE INSPECTED UNTIL LAND DISTURBANCE IS COMPLETE AND THE

AREA ABOVE MEASURE HAS BEEN PERMANENTLY STABILIZED.

4. ONCE ALL SOIL HAS BEEN STABILIZED AND CONSTRUCTION ACTIVITY HAS BEEN COMPLETED, THE COMPOST MEDIA MAY BE REMOVED FROM THE PROJECT SITE OR DISPERSED WITH A LOADER, RAKE, BULLDOZER, OR SIMILAR DEVICE AND MAY BE INCORPORATED INTO THE SOIL AS AN AMENDMENT OR LEFT ON THE SOIL SURFACE TO AID IN PERMANENT SEEDING OR LANDSCAPING, EXCEPT IN WETLAND AREAS. THE MESH NETTING MATERIAL SHOULD BE EXTRACTED FROM THE MEDIA AND DISPOSED OF PROPERLY. PHOTODEGRADABLE MESH NETTING MATERIAL, IF USED, DOES NOT NEED TO BE EXTRACTED AND DISPOSED OF. USING BIODEGRADABLE COMPOST SOCKS COMPLETELY ELIMINATES THE NEED AND

COST OF REMOVAL AND DISPOSAL.
