The City of Fairfax began a public education campaign in Fall 2021 related to its proposed Stormwater Utility (SWU), a fee-for-service mechanism that would create a dedicated funding source for the City’s stormwater management capital needs. Under the proposed SWU, private property owners would be assigned one Billing Unit (BU) per 500 square feet of […]
Modeling stormwater facilities accurately in hydraulic programs depends greatly on facility specific characteristics, including stage-storage and elevation-discharge curves. It is typically assumed that these facilities are in ‘good’ operating condition with full design capacity. True field conditions, however, may uncover factors prohibiting these facilities from achieving true design capacities. It is imperative that best management […]
Urbanization results in higher runoff, sediment, and nutrients loadings, causing degraded water quality downstream. Event mean concentration (EMC) is a common method used in most watershed models for estimating nutrients and sediment loads in urban runoff. Land use and antecedent dry period (ADP) are known factors affecting water quality (WQ) EMCs; however, several studies have shown […]
