Dear Mr. Causey:

Director
The Division of Energy, Mineral and Land Resources (DEMLR), received a Stormwater
Management Permit Application for the subject project on May 11, 2017. A preliminary review
of that information has determined that the application is not complete. The following
information is needed to continue the stormwater review:
Revise the supplement to reflect the plans that the internal pond side slopes are 3:1, not
2:1.
2. Revise C-910, OCS-EC-3 section view to show 2:1 for the outer slope to be consistent
with the plan view.
3. Provide and label a SCM access easement to the nearest public right-of-way [General
MDC 9]. Since there is not a site or grading plan sheet, please show this on the post -
construction drainage plan sheet.
4. Provide supporting calculations to demonstrate that the two forebays sum to 15-20% of
the main pool volume [MDC 5].
5. Provide a trash rack on the riser [MDC 10].
6. Provide a site specific SCM planting plan. List the species, and show where on the shelf
each species should be planted [MDC 11].
7. Please note that a permit modification will be required for the future phases of the
project.
