The City of Fairfax has taken an active role in restoring the city’s stream channels. The need for stream channel restoration is a result of the increase in stormwater flows over the years. The main source of this increase is from development in the city. When open areas are developed and paved, the amount of runoff increases because the infiltration capacity of the land is reduced. This water enters the storm drains, which eventually drains to the city’s open stream channels.

Current city regulations require stormwater management for new developments and redevelopment (see City of Fairfax Code). Stormwater management is a means to control excess storm runoff resulting from the development of a site. Stormwater management measures include stormwater management ponds and underground detention vaults to hold excess stormwater so that it can be released at a rate equal to the water leaving the site prior to development. Because much of the city was development prior to the issuance of stormwater management regulations, there is a significant amount of uncontrolled stormwater entering the city’s stream channels. Many of the streams are not able to handle the existing storm flows, which has resulted in severe stream bank erosion and increased sediment loading.
