GS -10 Caloosahatchee Cross-link Project

Issue Statement: Southwest Florida is faced with

impaired water bodies; a lack of stormwater

storage and groundwater recharge; and a loss of

both habitat and wildlife corridor connectivity.

Identifying Solutions: Regional partnership with

multiple public agencies/private entities to

proactively plan for:

water quality enhancements

storage solutions

recharge solutions

increased habitat

and enhanced wildlife corridor connectivity.

Environmental Impacts on

Caloosahatchee River

Watersheds have a need for improved water quality

The estuarine portion of the Caloosahatchee River has nitrogen impairment

Load Allocation to nonpoint sources (including Ag and non-MS4 stormwater) also have the same 23%

requirement.

Unbalanced seasonal freshwater flows

Regional Issue:Habitat

Development has eliminated habitat

Comprehensive effort to link parcels

Regional partners needed to make a larger, more timely impact

How do we make a change?

Regional private/public agency partnership

Proactively plan to reduce negative impacts on the Caloosahatchee River

Opportunity for Change:

GS10 Caloosahatchee Crosslink

New reservoir: Section10 Minor Impoundment

Inter-basin connection between C43, Carlos

Waterway, Bedman Creek, Hickey’s Creek,

Orange River and Caloosahatchee River

Water quality discharge flow path for C43

Reservoir

Additional flows for Greenbriar Swamp

restoring hydro periods, flows

Increased greenspace

Restored Habitat and Connectivity
