The design storage is for the runoff from all
impervious surfaces resulting from 1-inch of
rainfall and is located above the permanent pool.
The permanent pool is designed for 85% TSS removal.
The runoff completely draws down to the permanent
pool in 5 days, but not less than 2 days.
The mean depth of the permanent pool is a miniTum of
3 feet.
The inlet structure is designed to minimize
turbulence and short circuiting.
6. Yes (jg�D All overflow and discharge flows through a
vegetative filter at least 30 feet in length.
7. Yes GNy� A method is used to provide even distribution of
runoff over,the length of the vegetative filter.
8. Yes �� The slope and width of the vegetative filter
provides non -erosive flow for the 10-year 24-hr
storm with a 10 vear, 1-hr intensity.

10. Yes Cj� The vegetative filter is natural, grassed or

Dear Sir
The Environmental Management Commission (EMC) recently adopted
new stormwater regulations which became effective on 1 January
1988 The new rules will affect much of the development taking
place in the 20 coastal counties Any development project _
located in a coastal county that is required to submit a
Sedimentation and Erosion Control Plan to a State, County or City
review agency, must comply with the newly adopted Stormwater
Regulations
The Division of Environmental Management has received a copy of
your Sedimentation & Erosion Control Plan (or your Stormwater
Management Plan) for the subject project. At this Lime your
submittal concerning Stormwater Management
Appears to be complete, and your project will be reviewed as
soon as possible
GIs not complete. The following information is needed to
complete your submittal Please submit the following items
within 30 days, or your project will be returned as
incomplete
For projects using density limits approach
A site plan that clearly indicates all built -upon
areas (i e., streets, driveways, walkways, building
footprints, etc )
_ Computations showing the percent built upon areas,
both existing and planned.
A copy of deed restriction(s) and restrictive
covenants which include the State as a beneficiary.
_ The attached submittal form should be completed for
projects using the density limits approach
Other
✓ For projects involving an engineered Stormwater
Management System
_ Plan and profile drawings of the collection and/or
disposal systems

Computations or other criteria used to support
design of the system
Volume of runoff
_ Volume of containment/disposal system
_ Dewatering time of containment/disposal
system.
Length of vegetative filter strip needed
Other A MA"P SHCbWI%lF F-W-U R E 4 S 3 ACRE
-RA-gceL W1T CIEARLY SHOWAL
_ Supporting data concerning the hydrogeology of the
site.
Seasonal high water table.
_ Infiltration capacity - saturated hydraulic
conductivity.
Other
Drainage pattern(s) for design storm event, and
drainage pattern(s) for runoff in excess of design
storm event.
_ A complete stormwater maintenance manual including
responsible party, quantitative and qualitative
criteria which would indicate when corrective
maintenance is required, and a periodic maintenance
table as needed.
A proposed monitoring program for the system
Other
Please be reminded that construction of the subject project may
not commence prior to approval of the Stormwater Management Plan.
