Exhibit_E_-_WATER_QUALITY_MANAGEMENT_PLAN_(WQMP)_DATED_OCTOBER_7_2022.pdf

This is a Water Quality Management Plan (WQMP) document dated October 7, 2022, prepared for the Crawford Canyon Park and Sidewalk Extension Project in Orange County, California. The WQMP outlines comprehensive water quality management strategies and best management practices (BMPs) required for the project, which includes site clearing, grading, parking lot construction, playground installation, concrete walkways, pedestrian bridges, landscaping, irrigation systems, electrical improvements, and storm drain construction along Crawford Canyon Road and Newport Avenue/Boulevard. The document establishes protocols for managing stormwater runoff, erosion control, sediment management, and pollution prevention throughout the project's construction and post-construction phases. The plan addresses site-specific conditions, identifies potential water quality impacts from construction activities, and prescribes mitigation measures to protect local water resources and comply with applicable water quality regulations and permit requirements.

The WQMP serves as a technical exhibit supporting the broader Crawford Canyon Park and Sidewalk Extension Project bid solicitation, which carries an estimated contract value of $5,635,000 and is restricted to six pre-qualified contractors. The document establishes environmental compliance requirements that all bidders and their subcontractors must incorporate into their project execution plans, including implementation of erosion and sediment control measures, stormwater pollution prevention practices, and post-construction water quality maintenance. These water quality management requirements are mandatory elements of project performance and must be detailed in contractor proposals to ensure responsive and responsible bids meet the County of Orange's environmental protection standards and regulatory obligations under applicable stormwater management and water quality laws.
