RFP 13436 - BHSA_Zip_Codes.pdf

This document is a geographic reference file prepared by the San Diego County Office of Business Intelligence for the Health and Human Services Agency (HHSA) Regional Boundaries mapping, supporting the RFP for Perinatal Outpatient Substance Use Disorder Services. The file delineates current geographic ZIP codes across five HHSA regions in San Diego County: North Coastal, North Inland, Central, East, and South. The document explicitly excludes historic and P.O. Box ZIP codes and provides a comprehensive listing of active ZIP codes organized by regional boundaries. The reference data was sourced from the San Diego County Enterprise Portal Geographic Information Systems database as of April 15, 2025, with contact information provided for Ricardo Gutierrez of the Office of Business Intelligence for questions regarding the geographic data.

This geographic mapping document serves as a foundational reference tool for the Perinatal Outpatient Substance Use Disorder Services RFP, which anticipates awarding up to five contracts (one per lot) with an initial base period of one year and four one-year renewal options. The ZIP code demarcation by HHSA region enables potential bidders and the County to clearly identify service delivery areas and geographic boundaries relevant to the contract opportunity, facilitating accurate proposal submissions and service area definitions for vendors responding to the solicitation.
