Greenville Watershed Master Plans
Putting Water in Its Place

From Reactive to Proactive

The Greenville Watershed Master Plan (WSMP) project recently achieved a major milestone: Completion of the stormwater drainage systeminventory. Close to 100 surveyors inventoried 1,161,000 linear feet (or 220 miles) of stormwater pipe within the City limits. Field crews also inventoried more than 16,000 structures including catch basins, culverts, and stream channels. Throughout the inventory process, the City has been able to identify numerous locations that were previously unknown. Public Works has cleared many of these locations, thus improving numerous drainage conditions.

Project Summary

The City of Greenville’s Stormwater Management Program is implementing a study process in the City’s watersheds. Between August and December, crews will be spread throughout the city's creeks and streams for a city-wide assessment of water quality, flooding, and erosion control issues. It's part of an effort to improve the city's stormwater system through a comprehensive evaluation of Greenville's watersheds.

The goal is to recommend and prioritize projects that will control flooding, stabilize streams, and improve overall water quality in the city and adjacent areas. Field activity is expected to last for several months, but the overall process will last longer and will include many opportunities to educate, inform, and involve the public. After the field work is completed, engineering analyses of potential watershed improvement projects will begin.

Seven (7) watersheds have been identified in the City of Greenville. The Master Plan will be developed for six of the seven (one watershed, Meetinghouse Branch, was completed in a pilot project). Click here for Executive Summary.

The six watersheds to be included in the WMP are:

  • Fork Swamp
  • Greens Mill Run
  • Hardee Creek
  • Harris Mill Run/Schoolhouse Branch
  • Johnsons Mill/Parker Creek
  • Swift Creek

What is a Watershed?

Everyone lives in a watershed! A watershed describes an area of land that contains a common set of streams and rivers that all drain into a single larger body of water, such as a larger river, a lake or an ocean. Within each watershed, all water runs to the lowest point - a stream, river, or lake. On its way, water travels over the surface and across farm fields, forestland, lawns, and city streets, or it seeps into the soil and travels as ground water. Watershed boundaries are defined by nature and therefore often overlap many areas.

You will learn all about the City’s watersheds during this study process as well as the watershed you live in. Information on how to protect our creeks, streams and rivers will also be provided.

How To Stay Involved

Your Participation Matters!

A variety of opportunities have been provided to obtain feedback from Greenville residents and stakeholders including a survey, attendance at community events and seven public meetings. See the Project Document section for the survey and meeting summaries and the Photo & Video Gallery for outreach images.

We Want to Hear From You!

Invite Us to Your Event – we are available to provide information and/or attend an event for your neighborhood or organization. Send us an invite!

Attend Our Events – we will host several events at key milestones during the process. Visit this page often for updates and announcements. Next event posted here

Send Us Your Photos – do you have any photos of flooding in your area, streams overflowing or just beautiful pictures of nearby creeks and streams? Share them with us – we want to know more about the landscape of your community.
