Site Design MeasuresProjects that create and/or replace between 2,500 and5,000 sq. ft. of impervious surface must implement one ormore of the following:1)Stream Setbacks and Buffers2)Soil Quality Improvement and Maintenance3)Tree Planting and Preservation4)Rooftop and Impervious Area Disconnections5)Porous Pavement6)Green Roofs7)Vegetated Swales8)Rain Barrels and Cisterns
Site Design MeasuresOPTION 1On project siteOPTION 2Off project site butwithin campus and insame watershedOPTION 3Combination of on-siteand off-siteOptions for implementing site design measures on project site orat another location on campus within the same watershed variesfrom campus to campus. Please work with your campus stormwater manager.

LID Design Standards(Low Impact Development)Required for “Regulated Projects” defined as projectsthat create and/or replace 5,000 sq. ft. or more ofimpervious surface: Site Design Measures Source Control Measures Numeric Sizing Criteria for Storm Water Retentionand Treatment Storm Water Treatment and HydromodificationManagement Measures
LID Design StandardsSource Control MeasuresSource control measures should be designed, constructed,inspected, and operated to control pollution-generatingactivities and sources, such as: Spills or leaks Vehicle and equipmentcleaning Floor drains Vehicle and equipment Building and groundsmaintenancemaintenance Indoor/outdoor pest control Fuel dispensing areas Fire Sprinkler Test Water Food service operations Storage of solid wasteSource control measures should be designed consistent with CaliforniaStormwater Quality Association’s (CASQA) Stormwater BMP Handbook forNew Development/ Redevelopment. For O&M procedures, consult CASQA’sStormwater BMP Handbook for Municipalities.
LID Design StandardsSource Control Measures (continued)Source control measures should be designed, constructed,inspected, and operated to control pollution-generatingactivities and sources, such as: Pools, decorative Drain or wash water fromfountains, and other water boiler drain lines,featurescondensate drain lines,rooftop equipment, Parking/storage areadrainage sumps, and othermaintenancesources Loading docks Non-storm water Outdoor storage ofdischargesequipment or materialsSource control measures should be designed consistent with CaliforniaStormwater Quality Association’s (CASQA) Stormwater BMP Handbook forNew Development/ Redevelopment. For O&M procedures, consult CASQA’sStormwater BMP Handbook for Municipalities.
For projects that create and/orreplace 5,000 sq. ft.For all “Regulated Projects”, Low Impact Development DesignStandards required. If impervious surfaces increase by .less than 50% .greater than 50%ExistingBuilding 12,000 sq ftExistingBuilding 12,000 sq ftBuilding Expansion to17,500 sq. ft.Building Expansion to21,000 sq. ft.Runoff from NEW imperviousarea must be treatedRunoff from existing and newimpervious area must be treated
LID Design StandardsSite Design MeasuresInfiltrate the 85th percentile rainfall event as determinedin the Numeric Sizing Criteria methods using Site DesignMeasures.Use the Post-Construction Water Balance Calculator toverify that the 85th percentile event has been capturedDetermine if there is remaining runoff to be addressed.If remaining runoff needs to be addressed, then SWTreatment/ Hydromodification is required throughbioretention or equivalent
LID Design StandardsStorm Water Treatment and RetentionStorm water treatment and retention must be designed to evapotranspire,infiltrate, harvest/use and/or biotreat storm water using one of thefollowing sizing criteria : Volumetric criteria:For detention basins, retentionbasins, and infiltration areas Flow-based criteria:For swales, sand filters, andscreening devicesPhotos source: CASQA BMP manual for New Development and Redevelopment
LID Design StandardsSW Treatment/ HydromodificationBioretention:Facilitiesdesigned toinfiltrate,evapotranspire,and/or biotreatrunoff.Specific guidelines outlined in MS4 permit Section F.5.g.2.d.CASQA’s BMP Stormwater Handbooks and the Central Coast Low Impact DevelopmentInitiative are great resources!

The process of site layout planning describes the design and allocation of site equipment such as tower cranes or containers.
Design, Construction and Operation of Landfill Gas Collection and Control Systems. The foundation of any LFGE project involves the design, construction and operation of a landfill gas collection and control system (GCCS). GCCSs require proper engineering design, construction and operation by trained personnel to maximize intended benefits.
