How Does Springfield Plan Review Differ from Greene County?

City of Springfield review is a coordinated process across building, zoning, public works, and stormwater functions. The building permit application routes structural, architectural, and MEP plans to the city's reviewers, while the site and civil plans pick up comments on grading, stormwater detention, water quality, and access. The items that surprise out-of-town design teams are the karst items: the sinkhole report and sinkhole permit are checklist items, not optional extras, and the geotechnical engineer should be scoped to produce a report that satisfies the city's reviewers, not just the structural engineer. Floodplain development permits are a separate track for parcels touching mapped floodplains, with elevation documentation and floodproofing details reviewed on their own merits. The city's design standards also govern how private development ties into public systems. Sewer extensions carry detailed checklists covering lateral slopes, cover depths, cleanouts, and manholes, plus county highway department signatures where the work touches county right-of-way and grading permits where county rules apply. Land disturbance permits cover erosion and sediment control during construction, with inspections that continue until the site is stabilized. Because these are separate permits with separate reviewers, the project schedule should sequence them honestly: a building permit does not authorize grading, and grading approval does not authorize building. The engineer maps every required permit at the start and tracks them as parallel workstreams.

Unincorporated Greene County permitting centers on the county's Resource Management office, which handles building permits, land-use review, and inspections for parcels outside any city limit. The submittal still needs engineered plans, but the review team is the county's staff rather than the city's, with different forms, fee schedules, and inspection request procedures. Karst does not disappear at the city limit: the county publishes sinkhole guidance and expects development to address sinkhole risk, and its reviewers will ask how the project handles known or suspected karst features. Floodplain, grading, and driveway access to county roads each follow county rules, and state permits enter the picture for highway access or work near streams and wetlands. The county path rewards early coordination for a different reason than the city path: fewer overlapping departments means fewer chances to catch a missed requirement in someone else's review. The engineer should confirm directly with county staff which permits a given scope triggers, because assumptions carried over from city projects do not always transfer. Septic systems are a county-path staple, since many unincorporated parcels are beyond sewer service; where city sewer is extended to a county parcel, the annexation question and the utility's extension requirements become part of the permit strategy. As with the city, the AHJ decides what is approved and on what timeline, so the submittal should be complete, internally consistent, and responsive to the county's published checklists.
