Right of Way/ Stormwater/ Fill Application
STORMWATER/ FILL PERMIT INSTRUCTIONS & REQUIREMENTS
- 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.
- An accurate site plan (8" x 14" minimum) must be attached with the application dearly showing the following:
- Limits of fill.
- Setbacks, buffers, easements, and existing vegetation to remain.
- Buildings, sidewalks, driveways, and other impervious areas.
- Locations and sizes of all retention areas including depth.
- Flow arrows.
- Retention areas shall have the following characteristics.
- Retention areas must be maintainable
- Maximum depth of six (6) inches.
- Side slopes of 6:1 or flatter
- All retention areas must be sodded.
- Typical section
- 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.
- Calculate the required cubic feet. 10,000 x 0.0415 = 415 cubic feet.
- 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.
- Calculate the required cubic feet. 21,780 x 0.083 = 1808 cubic feet (rounded up)
- Calculate the required square footage at a 6-inch depth. 1808 / .5 = 3,616 square feet required.
- Example 1: Lot size is 10,000 square feet.
- Rain gutter downspouts must discharge to a retention area.
- Proposed driveways and sidewalks must slope to a retention area.
- All disturbed areas must be sodded.
- 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.
- No storm water shall runoff to adjacent property owners.
- Erosion control measures shall be provided during and after construction.
