Solicitation # 2024110840
The City of Norco is undertaking the 2050 General Plan Update Project to establish a long-term vision for land use, development patterns, infrastructure planning, and resource conservation within the city's incorporated limits.

The plan incorporates goals and policies developed through community outreach to enhance public facilities, parks, and transportation safety.

A Program Environmental Impact Report has been developed to ensure compliance with CEQA guidelines, identifying a significant environmental impact regarding paleontological resources that requires specific mitigation. The project also mandates adherence to the Americans with Disabilities Act for pedestrian infrastructure and requires strict confidentiality regarding tribal cultural resources. Additionally, any construction activities involving soil disturbance must comply with NPDES General Permit requirements, including the development of a Stormwater Pollution Prevention Plan.
