This permit shall be effective from the date of issuance until July 27, 2019, and
shall be subject to the following specified conditions and limitations:
I. DESIGN STANDARDS
This permit is effective only with respect to the nature and volume of
stormwater described in the application and other supporting data.
This stormwater system has been approved for the management of
stormwater runoff as described in Section 1.6 on page 4 of this permit. The
stormwater controls have been designed to handle 21,039 sf of building
roof tops, and 19,196 sf of permeable asphalt parking areas. Based on
design, the permeable pavement sections have been given a 53 % credit,
yielding a net 8985 sf of impervious area.
3. All stormwater collection and treatment systems must be located in either
dedicated common areas or recorded easements. The final plats for the
project will be recorded showing all such required easements, in
accordance with the approved plans and permit.

The runoff from all built -upon area within the permitted drainage areas of
this project must be directed into the permitted stormwater control system.
The following design criteria have been provided for the infiltration basins
and must be maintained at design condition:
a. Total Site Area:
1.42 acres
b. Total Impervious Surfaces: roof tops

this permit, the approved plans and specifications, and other supporting
documentation. Any deviations from the approved plans and
specifications must be noted on the Certification. A modification may be
required for those deviations.
7. If the stormwater system was used as an Erosion Control device, it must
be restored to design condition prior to operation as a stormwater
treatment device, and prior to occupancy of the facility.
8. Access to the stormwater facilities shall be maintained via appropriate
easements at all times.
The permittee shall submit to the Director and shall have received
approval for revised plans, specifications, and calculations prior to

the stormwater management measures, built -upon area, details,
etc.
b. Project name change.
C. Transfer of ownership.
d. Redesign or addition to the approved amount of built -upon area or
to the drainage area.
e. Further subdivision, acquisition, lease or sale of all or part of the

file by the Permittee at all times.
12. The Director may notify the permittee when the permitted site does not
meet one or more of the minimum requirements of the permit. Within the
time frame specified in the notice, the permittee shall submit a written time
schedule to the Director for modifying the site to meet minimum
requirements. The permittee shall provide copies of revised plans and
certification in writing to the Director that the changes have been made.

This permit is not transferable except after notice to and approval by the
Director. In the event of a change of ownership, or a name change, the
permittee must submit a formal permit transfer request to the Division of
Water Quality, accompanied by a completed name/ownership change
form, documentation from the parties involved, and other supporting

Example #1 bir-M Q13, iO3+PG431
Project is a lot with a maximum allowed BUA of 5,000 sq. ft. that drains to class SC waters.
Project proposes a 1,000 sq. ft. permeable concrete driveway with a 6" gravel base.
Managed grass factor = 0.6
1000 x 0.6 = 600 square feet is counted as managed grass.
1000 - 600 = 400 square feet is counted as built -upon area.
5000 - 400 = 4,600 square feel available for house and other BUA.
Example #2
Project is a high density commercial site with a 5,000 square foot parking lot.
Project is within 1/2 mile of and draining to SA waters. An infiltration system is proposed.
The parking lot will handle <100 cars per day and is a flexible pavement with a 4" gravel base.
Managed grass factor is one half of 0.4. = 0.2
5000 x 0.2 = 1000 square feet is counted as managed grass.
5000 - 1000 = 4,000 square is counted as impervious.
The total BUA used to calculate the minimum volume draining to the
infiltration system can be reduced by 1,000 square feet.

Example #1 b.czb bg 103 laym-431
Project is a lot with a maximum allowed BUA of 5,000 sq. ft. that drains to class SC waters.
Project proposes a 1,000 sq. ft. permeable concrete driveway with a 6" gravel base.
Managed grass factor = 0.6
1000 x 0.6 = 600 square feet is counted as managed grass.
1000 - 600 = 400 square feet is counted as built -upon area.
5000 - 400 = 4,600 square feet available for house and other BUA.
Example #2
Project is a high density commercial site with a 5,000 square foot parking lot.
Project is within 1/2 mile of and draining to SA waters. An infiltration system is proposed.
The parking lot will handle <100 cars per day and is a flexible pavement with a 4" gravel base.
Managed grass factor is one half of 0.4. = 0.2
5000 x 0.2 = 1000 square feet is counted as managed grass.
5000 - 1000 = 4,000 square is counted as impervious.
The total BUA used to calculate the minimum volume draining to the
infiltration system can be reduced by 1,000 square feet.
