Insome cases, runoff ponds behind the berm and gradually flows through it or is infiltrated. === Biofilter ===A bioretention stormwater best management practice featuring an impermeable linerand underdrain that prevents infiltration of runoff into the underlying native soil; providessedimentation and filtration of urban runoff as it passes through the mulch layer, engineeredfilter media and vegetation root zone. === Bioretention ===A stormwater filtration and infiltration practice. The practice is a shallowexcavated surface depression containing a prepared soil mix, mulch, and planted with speciallyselected vegetation. The system is engineered to temporarily store runoff in the depression andgradually filters it through the mulch, engineered soil mix, and root zone. They removepollutants from runoff through filtration in the soil and uptake by plant roots and can help toreduce runoff volume through evapotranspiration and infiltration. = C ==== Check Dam ===Structures constructed of a non-erosive material, such as suitably sizedaggregate, wood, gabions, riprap, or concrete, used to slow runoff water to allow sedimentation,filtration, evapotranspiration, and infiltration into the underlying native soil. Can be employed inpractices such as dry and enhanced grass swales. === Cistern ===Tank used to store rainwater (typically roof runoff) for later use. = D ==== Depression Storage ===A technique for incorporating shallow depressed areas into urbanlandscaped areas for storing and infiltrating runoff. Typically, depression storage areas aresmall and have limited capacity and limited duration of retention in order to address propertyowner concerns relating to insects, damage to structures and inconvenience of ponded water ontheir property. === Detention ===The temporary storage of stormwater to control discharge rates, and allow forsedimentation. === Drawdown Time ===The period between the maximum water level and the minimum level (dryweatheror antecedent level). === Dry Swale ===Linear bioretention cells designed to convey, treat and attenuate stormwater runoff;The engineered filter media soil mixture and vegetation slows the runoff water to allowsedimentation, filtration through the root zone, evapotranspiration, and infiltration into theunderlying native soil. = E==== Evapotranspiration ===The combined loss of water to the atmosphere from land and watersurfaces by evaporation and from plants by transpiration. === Enhanced Grass Swale ===Vegetated open channels designed to convey, treat and attenuatestormwater runoff, also referred to as enhanced vegetated swales. Enhanced grass swales arenot capable of providing the same water balance and water quality benefits as dry swales, asthey lack the engineered soil media and storage capacity. === Environmental Impact Report (EIR) ===The evaluation of the possible effects that may arise from aproposed project on the environment, together consisting of the natural, social and economicaspects. === Exfiltration ===Loss of water from a drainage system as a result of percolation or absorption intothe surrounding medium (e.g., the infiltration of water into the native soil through a perforatedpipe wall as it is conveyed). = F = = G = = H = = I = = J = = K = = L = = M = = N = = O = = P = = Q = = R = = S = = T = = U = = V = = W = = X = = Y = = Z =
