The Division of Energy, Mineral and Land Resources (DEMLR), received a Stormwater
Management Permit Application for the subject project on August 1, 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:
1. Remove the "preliminary" and "conceptual" notes on all plan sheets. Plans must be final
plans for permitting [02H .1042(2)(g)].
2. Add the proposed contours to the grading plans to show all proposed grading (roads,
swales, lot grading, etc.) [02H .1042(2)(g)(iv)].
3. Show on the plans boundaries of all surface waters, wetlands, flood zones, and vegetated
setbacks, or a note on the plans that none exist [02H .1042(2)(g)(iii)].
4. The pond bottom and sediment cleanout elevations are not consistently shown on the
O&M Agreement, Supplement form, and the plans.
5. What is the shaded square in the middle of the pond riser detail? If it is a weir, please
label invert elevation and dimension.
6. Provide energy dissipation at HW -90; and supporting calcs to show non-erosive for the
10 -yr storm [General MDC 4].
7. Show an access and maintenance easement around the SCM to a public right-of-way
[General MDC 8 & 9].
