2. The overall tract built -upon area percentage or lot sizes
for the project must be maintained at levels at least as
stringent as the low density levels specified in the
stormwater rules.
3. The development must demonstrate that no areas within the
project site are of such high density that stormwater
runoff threatens water quality.
4. Approved plans and specifications for projects covered by
this permit are incorporated by reference and are
enforceable parts of the permit.
5. The only runoff conveyance systems allowed will be
vegetated conveyances such as swales with minimum side
slopes of 3:1 (H:V) or curb outlet systems as defined in
- - the stormwater rules -and -approved by the Division.
6. No piping shall be allowed except:
a. That minimum amount necessary to direct runoff
beneath an impervious surface such as a road
b. That minimum amount needed under driveways to
provide access to lots.
C. The 1375 LF of gravel trench and sock drain piping
as shown on the revised site plan dated July 17,
1998.
7. Projects covered by this permit will maintain a minimum
30 foot wide vegetative buffer between all impervious
areas and surface waters.
8. No homeowner/lot owner/developer shall be allowed to fill
in, alter, or pipe any vegetative practices (such as
swales) shown on the approved plans as part of the
stormwater management system without submitting a
revision to the permit and receiving approval from the

9. Each of the lots in the subdivision will be limited to
the amount of built -upon area indicated in the approved
plans and consistent with item 1 above.
10. The permittee is responsible for verifying that the
