Stormwater Design Standards
The Stormwater Design Standards can be found in Chapter 2 of the Riverton City Standards Specifications and Plans.
Low Impact Development (LID) standards for public right-of-way.  The City must govern public LID infrastructure to assure flood control and water quality systems are adequate.  LID systems generally results a more local drainage system rather than shared regional drainage and park systems, and landscape designs involving more than just lawn, potentially increasing maintenance cost and stormwater fees.  The City desires to limit stormwater fees and help the general public understand their urban impacts by placing local LID landscape maintenance responsibilities on property owners.   The following standard detail is intended to simulate pre-development hydrology as much as practicable, conform to the permit retention standard, manage flood impacts and facilitate manageability by the resident and City.

Low Impact Development for private development
.  Private LID infrastructure has more options as it is maintained by the private entity.  It simply must conform to Permit and City Stormwater Design Standards for flood control, water quality and Long-Term Stormwater Management criteria.      

To comply with the Clean Water Act the City encourages development to reduce their runoff impact by retaining all or a portion of runoff.  Development that conforms to this approach can receive up to a 45% reduction of their Stormwater Utility Fee.  Stormwater Utility Fee Adjustments may be apply for by application.
