HISTORY

Worked in and around watershed for more than three decades

Have made flow measurements during and following major events

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

Page 16: Water Strategy Task Force August 11, 2014. BACKGROUND Figure 1. Stream Functions Pyramid Highlights Stream Restoration Foundations Needed to Attain Higher

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
