Choose the Right Rain Garden - First Step

Are EITHER of the following conditions true?

Rain garden will be located:

  • in floodplains1 or other sensitive areas such as wetlands2, riparian areas and buffers3, & habitat4
  • over septic systems5

 

Yes     |     No     |     Start Over

 

If any of the above conditions are true, answer Yes. If all of the above statements are false (preferred), answer No. Answering yes means that this location is unsuitable for a rain garden. A lack of information from any one of the following sources does not necessarily mean that your site is without any sensitive areas. The ultimate decision will fall to those with jurisdiction, so be sure to contact any agencies mentioned for assistance if in doubt. 


1 Use the 100-year floodplain area as a minimum. The 25-year floodplain may also be appropriate depending on the development standards and regulatory environment in your jurisdiction.

2 Wetlands may or may not be recognized and mapped as "jurisdictional". If a wetland has not been mapped, it may still fall under multiple jurisdictions. Rain gardens in wet or seasonally wet areas could cause damage to your property.

A riparian area can be simply defined as land adjacent to a waterway that either influences or is influenced by that waterway.

4 Numerous animal species provide important hydrologic benefits to our watersheds. There may be sensitive uplands that provide important habitat to some of our specialized native animal species.

5 Avoid installing rain gardens over a septic field or other infiltration septic system; this could ruin your septic system in a variety of ways.
