Watershed Management Plan

A watershed management plan defines and addresses existing or future water quality problems.

Experience has shown that effective watershed management includes active participation from stakeholders, analysis of the specific causes and sources of water quality problems, identification of measurable water quality goals, and implementation of specific actions needed to solve those problems.

Neighborhood Environmental Stewardship Team

The Neighborhood Environmental Stewardship Team (NEST) concept is based on the idea of promoting neighborhood involvement in environmentally friendly projects to protect and restore our water resources. The NEST program projects focus on providing watershed education and getting neighbors involved in activities that improve their neighborhoods and enhance their watershed. The program goal is to help citizens and neighborhoods become advocates and champions for the watersheds they live in. The NEST program was developed in response to a need to get citizens and the general public better educated and more involved in the management and protection of the water resources of Sarasota County.

Drainage Basins

Watersheds are areas of land with waterways that flow to a common destination. The boundaries between watersheds are elevated areas called divides. In this Atlas, the watersheds are composed of groups of creeks that flow to a single bay or group of bays. Drainage basins are subunits of watersheds and are defined by the main creek that flows through them. Sarasota County has five watersheds, named after the bays or river, and 28 drainage basins, named after the creeks. Stormwater improvements to reduce flooding and improve water quality are based on the drainage basin unit. Learn more about watersheds »
