(http://www.fws.gov/chesapeakebay/newsletter/Fall11/Pyramid/Pyramid.html).
HISTORY
Worked in and around watershed for more than three decades
Have made flow measurements during and following major events
1944 CONDITIONS
2014 CONDITIONS
BACKGROUND
Generally flows are from the northeast to southwest Low flows occur from the commonly accepted watershed The larger the rainfall event/season, the more water that
will enter from the Corkscrew Watershed from the east
BACKGROUND
Basin Management Action Plan for Nitrogen TMDL on freshwater portion of river
Watershed is from BUS 41/SR 739 to SR 82 Overall Nitrogen reduction is 23% Reduction is planned over three five-year periods City of Bonita Springs’ reduction is 3,301#/year
(2,058#/year of credit and 1,243#/year supplement)

DISCUSSION
Density Intensity
FLOW REGIMES
Existing developments have three major types of discharge:– None– Gravity– Pump
Today SFWMD prefers gravity and will generally only allow a pump system with a single entity as system operator such as a governmental body
SOLUTIONS
Do nothing Alter design criteria for new projects Provide incentives for upgrades to existing properties
Fix only items that are created by needs of City and not rest of watershed
The City’s DRGR, as many have stated, is small relative to the Lee County portion and it is at the downstream end
SOLUTIONS
LID– Rain Gardens
Filter Marshes Pervious Pavement (+/-)
SOLUTIONS
Spring Creek– Challenge of 298 District– Interstate openings
Rosemary Canal
