Subject: Request for Additional Information
Stormwater Permit No. SW5190501
Chatham Charter School — Recreation Fields Expansion
Chatham County
Dear Mr. Norris:
The Division of Energy, Mineral and Land Resources (DEMLR), received a Stormwater
Management Permit Application for the subject project on May 22, 2019. A review of that
information has determined that the application is not complete. The following information is
needed to continue the stormwater review:
Please note that the project site is located within 5 miles of Siler City Municipal Airport
(Section II, 5) See Session Law 2012-200, Part VI for more information regarding BMP
types to be used. This does not affect your design as shown, however it should be
corrected on the application and kept in mind when designing the Phase II quantity
control.
2. Please include the area of the surface waters that exist within the property boundary, for
example the unnamed tributary of Blood Run Creek (Section IV, 6). If there are surface
waters present on the property site and the total surface water area is less than 0.01 acres,
you may write "< 0.01" in this section and treat it as zero for calculation purposes.
3. Please recalculate the Total Project Area and Project Percent of Impervious Area if
needed. (Section IV, 7 & 8)
4. Please correct the drainage area information in Section IV, 10. For low density projects,
the Total Drainage Area is comprised of only of an Onsite Drainage component, which is
the Total Project Area, listed in Section IV, 7. There should not be any off -site drainage
areas or off -site impervious areas.
5. Please provide documentation of the qualifications and identity of the individual who
made the on -site wetland determination (Section VI, 8, m).
