Section 3 Environmental Setting and Project Description
Beach and Orangethorpe Mixed-Use Specific Plan Draft Program EIR SECTION 3 ENVIRONMENTAL SETTING AND PROJECT DESCRIPTION 3.1 PROJECT LOCATION The Beach and Orangethorpe Mixed-Use Specific Plan (BOMUSP) project site is located in the City of Buena Park in Orange County, California. The project site is bordered by Melrose Street to the north, Beach Boulevard (State Route [SR]-39) the west, Orangethorpe Avenue to the south, and Brenner Avenue to the east. Regional access to the project site is provided by I-5 to the north and SR-91 to the south. The regional location and local vicinity of the project site are depicted on Exhibits 3.1-1 and 3.1-2, respectively. 3.2 ENVIRONMENTAL SETTING 3.2.1 REGIONAL PLANNING CONSIDERATIONS Southern California Association of Governments The Southern California Association of Governments (SCAG) is the Metropolitan Planning Organization (MPO) for six counties: Los Angeles, Orange, San Bernardino, Riverside, Ventura, and Imperial. The region has a population that exceeds 18 million persons in an area of more than 38,000 square miles. SCAG is mandated by the federal government to research and develop plans for transportation, growth management, hazardous waste management, and air quality. As the designated MPO, the federal government has also mandated SCAG to research and draw up plans for transportation, growth management, hazardous waste management, and air quality. SCAG undertakes the following activities: • To maintain a continuous, comprehensive, and coordinated planning process resulting in a Regional -
4.5 Bioretention
4.5. Bioretention (rain gardens) Bioretention Bioretention areas typically are landscaping features adapted to treat storm water runoff. Bioretention systems are also known as Mesic Prairie Depressions, Rain Gardens, Infiltration Basins, Infiltration Swales, bioretention basins, bioretention channels, tree box filters, planter boxes, or streetscapes, to name a few. Bioretention areas typically consist of a flow regulating structure, a pretreatment element, an engineered soil mix planting bed, vegetation, and an outflow regulating structure. Bioretention systems provide both water quality and quantity storm water management opportunities. Bioretention systems are flexible, adaptable and versatile storm water management facilities that are effective for new development as well as highly urban re-development situations. Bioretention can readily adapt to a site by modifying the conventional “mounded landscape” philosophy to that of a shallow landscape “cup” depression. Such landscape depression storage and treatment areas fit readily into: parking lot islands; small pockets of open areas; residential, commercial and industrial campus landscaping; and, urban and suburban green spaces and corridors. Bioretention works by routing storm water runoff into shallow, landscaped depressions. These landscaped depressions are designed to hold and remove many of the pollutants in a manner similar to natural ecosystems. During storms, runoff ponds above the mulch and Engineered Soil Mix in the system. Runoff from larger storms is generally diverted past the facility to the storm drain system. The runoff remaining in the bioretention facility filters through the Engineered Soil Mix. The filtered runoff can either be designed to enhance groundwater infiltration or can be collected in an underdrain and discharged per local storm water management requirements. -
