A. Basic Context


B. County Provides Regional Services Across Municipalities

  1. Elections
    • County Elections Division runs all elections in every municipality (polling places, mail ballots, certification).
    • Municipalities provide polling locations (schools, fire halls), but county controls administration.
  2. Courts & Justice
    • Criminal and civil cases from every municipality flow into the county Court of Common Pleas.
    • Local police file charges, but prosecutions run through the county District Attorney.
    • County Jail holds pre-trial detainees from every borough/township.
  3. Public Health
    • County Health Department enforces food safety, air quality, immunizations countywide.
    • Municipalities don’t run their own health departments.
  4. Human Services
    • County DHS provides child protection, foster care, behavioral health, aging services across all 130 municipalities.
    • Delivered through nonprofit contracts and community providers embedded locally.
  5. Transit & Mobility
    • Pittsburgh Regional Transit (PRT), overseen by county, serves riders in dozens of municipalities.
    • Municipalities have no independent transit systems.
  6. Infrastructure & Parks
    • County Public Works maintains county-owned bridges/roads that cross municipal boundaries.
    • Nine county parks supplement local municipal parks and recreation.
  7. Property Assessment
    • County maintains uniform property values; municipalities and school districts then levy taxes based on these assessments.

C. Municipalities Retain Local Control


D. Shared or Overlapping Roles


E. Fiscal and Taxation Interactions


F. Collaboration & Tensions


Summary

Interaction between Allegheny County and its municipalities is a layered system of complement and overlap. Municipalities handle hyper-local services (police, zoning, trash), while the county manages regional systems (elections, courts, health, human services, transit, assessments). Funding and oversight flow downward from the county into local governments, but authority remains split, creating both collaboration and friction. The county is the glue that holds together 130 independent jurisdictions without dissolving their autonomy.
