What is stormwater? It is just what it sounds like: water from a storm. Any precipitation that falls from the sky, including rain, hail, and snow, is considered stormwater.
In a natural landscape without development, stormwater is absorbed into the ground or falls into bodies of water. This gives needed water to plants and animals and replenishes reserves of surface and groundwater.
In contrast, in an urban landscape, stormwater falls onto impervious surfaces (surfaces that do not absorb water) such as roads, sidewalks, rooftops, or parking lots and is not soaked up by the ground. As a result, the falling water is swept across these surfaces as runoff.

Poorly managed stormwater runoff can cause a host of problems, including:
- Flooding. As stormwater runs off roofs, driveways and lawns, large volumes quickly reach streams, causing them to rise quickly and flood, instead of a natural slow and steady water rise. When more impervious surfaces exist, flooding occurs more rapidly and can be more severe, resulting in damage to property and people.
- Pollution. Stormwater running over roofs, driveways, roads and lawns will pick up pollutants such as oil, fertilizers, pesticides, dirt/sediment, trash, and animal waste. These pollutants "hitch a ride" with the stormwater and flow untreated into local lakes, rivers and streams, polluting our waters. Eventually, we usher some of that water into treatment plants to produce the water we use every day, and drink. It's a cycle, and our stormwater systems are a critical part of making sure the water we return to the environment is not polluted.
- Bank Erosion. When stormwater flows into rivers and streams at unnaturally high volumes and speeds, the power of these flows can cause severe erosion. Eroding banks can eat away at neighboring property, create dangerous situations, and damage natural habitat for fish and other aquatic life. This erosion is another source of sediment pollution in waterways.
Stormwater Management is the use of specific practices, constructed or natural, to reduce, temporarily detain, slow down and/or remove pollutants from stormwater runoff. Stormwater management practices are essentially designed to restore or mimic some of the natural processes provided by the vegetative cover that existed prior to land disturbance. In many regions of the country, this native vegetative cover includes trees and shrubs.
Read the Stormwater Ordinance (PDF) for the Town of Randolph to understand how it help to protect the health, safety, general welfare and environment in the management, operation and maintenance of the Town's stormwater system.
All land disturbances meeting the following categories require review and authorization by the Randolph Stormwater Authority:
|Land disturbance 5,000 square feet to 21,780 square feet (1/2 acre)
|Land disturbance greater than 21,780 square feet
|Projects where proposed use has higher potential pollutant loads

Each community with a municipal separate storm sewer system (MS4) in designated urbanized areas must develop a Stormwater Management Program (SWMP) that will guide its activities under the 2016 MS4 general permit. This SWMP was developed by the Town of Randolph to protect water quality and reduce the discharge of pollutants from the municipality's storm sewer system to the maximum extent practicable (MEP) as described herein.
The SWMP is comprised of four volumes.
- SWMP Volume 1 - Stormwater Management Plan (PDF)
- SWMP Volume 2 - Illicit Discharge Detection and Elimination (IDDE) Plan (PDF)
- SWMP Volume 3 - Good Housekeeping and Pollution Prevention (O&M) Plan (PDF)
- SWMP Volume 4 - Annual Reporting
Please dispose of your pet waste properly by placing it in a trash bin, not down a storm drain or left on the ground. Improper disposal will lead to contamination of our water supply. Thank you!
