Outsourcing Stormwater Control Plan

Impervious surfaces such as buildings, homes, roads, sidewalks, parking lots can significantly alter the natural hydrology of land, change the volume and rate of runoff as well as the amount of suspended or dissolved substances entering local streams.

In some cases, a change in the number of impervious surfaces can change the distribution of water in a given area, affecting local water bodies, wetlands and associated fauna and flora. The project design includes measures to reduce the level of runoff and pollutants in post-development runoff. Therefore, It is important to have a Storm Water Control Plan when developing on your site and it should get a permit from the community before you do any work on your construction site.

There are a few methods that have been successfully used:

  1. Disperse runoff from roofs or pavement to vegetated areas: This is the simplest option. Downspouts can be directed to vegetated areas adjacent to buildings or extended via pipes to reach vegetated areas further away. Paved areas can be designed with curb cuts, or without curbs, to direct flow into the surrounding vegetation.
  2. Permeable Pavement: This option can be easy to install and maintain, cost-effective, and can add aesthetic value to your project. Permeable pavements may include pervious concrete, pervious asphalt, porous pavers, crushed aggregate, open pavers with grass or plantings, open pavers with gravel, or solid pavers.
  3. Cisterns or Rain Barrels: Use of cisterns or rain barrels to comply with this requirement is subject to municipality approval. Planning and Building Permits may be required for larger systems.
  4. An above-ground planter box may be appropriate if the development site lacks level landscaped areas for dispersion and pervious pavements are not practical. Planter boxes and bioretention facilities can treat runoff from impervious surfaces 25 times their area (sizing factor of 0.04).

To achieve compliance with the stormwater requirements for Land Development projects, the compliance for each project must be carefully documented. It should be included basic information about your site:

  • Project Name/Number
  • Application Submittal Date
  • Project Location
  • Name of Owner or Developer
  • Project Type and Description
  • Total Project Site Area
  • Total New Impervious Surface Area
  • Total Replaced Impervious Surface Area
  • Total Pre-Project Impervious Surface Area
  • Total Post-Project Impervious Surface Area
  • Runoff Reduction Measures Selected
