Stormwater Management

Know Where Your Drinking Water Comes From

North Port is unique in that the Stormwater drainage system of roadside swales, ditches, canals and the Myakkahatchee Creek collect rainwater which the City uses as its main potable water supply.

Everyone wants clean water, but the choices we make today when maintaining lawns and septic systems can affect our water resources tomorrow. The good news is that you can help. Read about your drinking water supply(PDF, 416KB) and learn simple ways to nurture a beautiful lawn and maintain your septic tank while protecting Florida's and North Port's environment.

Stormwater Quality Monitoring

Approved by the Florida Department of Environmental Protection in May 2009, the City's Water Control Monitoring Plan defines the procedures to be used to monitor the quality of water found in the City's natural surface water bodies. The approved plan allows the use of hydrobiological (HB) monitoring data and sampling sites to satisfy the monitoring requirements of the national pollutant discharge Elimination System (NPDES). The sampling locations provide specific water quality data for the surface water runoff from the City of North Port. To view a copy of the annual NPDES Report, please contact the Stormwater Manager of the Department of Public Works at 941-240-8050.

To report a surface water quality pollution issue, please contact the North Port Stormwater Manager at the Department of Public Works at 941-240-8050.

A Charlotte Harbor Water Atlas is available on the Coastal and Heartland National Estuary Partnership (CHNEP) website to provide the public with comprehensive and current water quality, hydrologic, and ecological data, as well as information on water resource issues.

Canal Watch Group

The City in cooperation with citizens of North Port have recognized the need to form a Canal Watch Group. The Canal Watch Group is open to anyone that wishes to conduct observations on any stretch of canal. Members will become ambassadors for our canals and environmental stewards for conserving North Port’s natural resources.

We take water quality concerns very seriously, and water quality calls are treated with priority at the City of North Port. In fact, the City in cooperation with citizens of North Port have recognized the need to form a Canal Watch Group.

Canal Watch Observation Forms can be downloaded here.(PDF, 125KB)

The canal system in North Port serves as the city’s drinking water source and must be protected from pollution. One major goal of the Canal Watch Group is to educate the public on how to minimize pollutants in our water resources through communication within our communities and neighborhoods. Another goal is to observe the canals for any illicit discharge or general unhealthiness. Examples of concern include excessive fertilizing or fertilizing during prohibited wet months.  Concerns also include oil sheen, illegal dumping, improper disposal of plant and animal waste, algae blooms, excessive turbidity, dead fish and other affected wildlife.  To help protect our water quality, North Port City Commission unanimously approved a resolution on October 9, 2018, to encourage the voluntary non-use of fertilizer year-around.

Fertilizer Ordinance

The City of North Port has adopted a fertilizer ordinance with enhanced regulations to protect drinking water quality and the environment. To learn how this ordinance affects you, read the ordinance(PDF, 235KB) and the 2023 amendment(PDF, 2MB) . A (PDF, 550KB)fertilizer fact sheet(PDF, 3MB) is also available to review the key points of the ordinance.


On May 9, 2023, the North Port City Commission approved Fertilizer Ordinance No. 2023-14 Amendment(PDF, 2MB). The notable changes that this includes are:

  • Use of fertilizer on turf grass is prohibited between April 1 through Sept. 30. Use of fertilizer on landscape plants is still permitted.
  • Commercial and Institutional Applicators no longer need a proof of training vehicle decal, but shall produce a copy of their Florida Green Industries Best Management Practices training certificate to enforcement staff if observed performing fertilizing activity.

All commercial and institutional applicators of fertilizer (except homeowners applying fertilizer on their own property) must receive training and certification in a City approved training program such as the Green Industries Best Management Practices (GI-BMP) training that is offered by UF-IFAS.

The training is hosted by Sarasota County Extension Services (941-232-6882). Once the training certificate is received, please bring a copy to the City of North Port's Development Services Department at City Hall. Applicators will need to produce a copy of this certificate to enforcement staff if observed performing fertilizing activity.

Residents encouraged to voluntarily not use fertilizer

On Tuesday, Oct. 9, 2018, North Port City Commission unanimously approved a resolution to encourage the voluntary non-use of fertilizer year-around(PDF, 140KB).

The City of North Port recognizes that fertilizers from many sources can enter into our waterways and may contribute to algal blooms including the Florida red tide organism, Karenia brevis, which has caused widespread detrimental effect along the coastal communities. These nutrient pollutants can affect the regional watershed, and the City of North Port desires to be part of a regional effort to improve water quality. Water quality is critical to the Charlotte Harbor estuarine system and watershed. It is also critical to the City of North Port’s environmental, economic, and recreational prosperity and to the health, safety and welfare of the citizens of the City.

The City of North Port’s Fertilizer Ordinance has a restricted period of April 1 through Sept. 30 each year which prohibits use of nitrogen and phosphorus fertilizer on turf, but landscape plants can still be fertilized with fertilizer containing 50% or more slow release nitrogen. In the period after September 30 and before April 1, fertilizing of both turf and landscape plants are allowed.

In a previous Commission meeting on Sept. 25, 2018, it was the desire of the North Port Commission to adopt a resolution as soon as possible to encourage non-use of fertilizers year-round for the health, well-being and safety of the community.

This resolution approved on Oct. 9, 2018, will contribute to a regional effort to reduce fertilizer runoff into waterbodies that flow to the estuary and ocean. This resolution encourages a voluntary non-use of fertilizer year-around, which is more restrictive than the City’s fertilizer ordinance.
