1. The first ½-Inch of runoff from the entire site must be maintained on lots less than 10,890 square feet (1/4 acre). One
inch of runoff from the entire site must be retained on lots more than 10,890 square feet.
2. An accurate site plan (8" x 14" minimum) must be attached with the application dearly showing the following:
a. Limits of fill.
b. Setbacks, buffers, easements, and existing vegetation to remain.
c. Buildings, sidewalks, driveways, and other impervious areas.
d. Locations and sizes of all retention areas including depth.
e. Flow arrows.

d. All retention areas must be sodded.
e. Typical section

Retention Area
4. Calculation of retention area is based on the entire lot size. Lots that are less than 10,890 square feet have a multiplier of
(0.0415) for ½-inch of runoff. Lots that are equal to or greater than 10,980 square feet have a multiplier of (0.083) for 1-
inch of runoff.
Example 1: Lot size is 10,000 square feet.
1)
Calculate the required cubic feet. 10,000 x 0.0415 = 415 cubic feet.
2)
Calculate the required square footage at a 6-inch depth. 415 / .5 = 830
square feet required. Example 2: Lot size is 21,780 square feet.
1)
Calculate the required cubic feet. 21,780 x 0.083 = 1808 cubic feet (rounded up)
2)
Calculate the required square footage at a 6-inch depth. 1808 / .5 = 3,616 square feet required.
5. Rain gutter downspouts must discharge to a retention area.
6. Proposed driveways and sidewalks must slope to a retention area.
7. All disturbed areas must be sodded.
8. Properties located in areas of the City with a designated storm water system (i.e. Florida Shores areas) must grade the
property
toward the City right-of-way, where possible.
