Stormwater Management System
City of Satellite Beach
The System
(insert map) (describe general lay of the
land)
Primarily City owned, operated and funded
System includes pipes/culverts, ditches, swales ponds, inlets, structures, baffle boxes, etc.
17.83 miles or 94,141 feet of pipe ranging from 6” to equivalent 8’ diameter along with 791 inlets and structures
Replacement value of pipe is $14,168,212
Much of system was built by developers that had different goals and regulations to abide by
What is Stormwater Management?
Operation of facilities (pipes, inlets, ditches, ponds, etc.) Maintenance of facilities Renewal and replacement of facilities Compliance with evolving State and Federal regulations NPDES MS4 Permit Indian River/Banana River Lagoon BMAP
Compliance with City Comprehensive Plan Goals/Objectives Addressing environmental changes Sea level rise
Near Future Concerns/Needs
Renewal and replacement Large portion of existing pipe was installed
in 1960’s/1970’s Much of this pipe has reached its useful
life BMAP compliance Established in January 2013 Allocated City pollutant load reductions 15 year compliance
Flood alleviation Sea level rise of up to 8 inches by 2040
and 13 inches by 2070 More intense and frequent large rainfall
events
Current Stormwater Masterplan Update
Update of 2001 Masterplan Incorporating 2013 Stormwater Quality Master Plan Inventory and condition assessment of faciliites Update of facility mapping Computer modeling of storm events (existing condition,
future conditions and proposed improvements)Cassia Basin - Ocean Spray and Willow

Funding - Revenue
City stormwater utility fee Established in 1997 Currently $104 per year per ERU or $2.89 per 1,000 SF of
impervious per month $512,000 in revenue per year Average rate in Florida is currently $2.78 per 1,000 SF of
impervious per month, average rate in Brevard County is $1.92 Rates for barrier island cities generally higher due to low
elevations, limited available land and tidal impacts Loans Grants
Funding – Expenditures
$160K debt service through 2020 Recommended five year renewal/replacements of $700K or
$140K per year BMAP compliance previously estimated at $566K per year
through 2028 Flood alleviation/capacity improvements can usually be
accomplished concurrently with renewal/replacement and treatment projects Assuming 25% grant funding for treatment projects, $423K
per year is needed Typical large scale project like Desoto or Cassia costs $1M to
$2M
