2.3.3.20 Storm Drainage (Runoff)

Storm Drainage (Runoff)

Drainage is a critical requirement for every subdivision. Inadequate drainage can lead to flooding , resulting in erosion, loss of stability or in property damage.  In addition, subdivisions that are not properly drained can result in damage to highways both in and downstream from the subdivision, resulting in a public safety hazard.

Storm water must be considered both in the subdivision and outside of it. The applicant may be required to have a drainage study or design prepared by a Professional Engineer or hydrologist. Drainage should be carried to a natural outfall or approved storm drain capable of carrying the additional flow.
