Due to Pittsburgh’s history and unique terrain, the City has several environmental conditions that can be impacted by developments ranging from fences to new skyscrapers. These environmental conditions are steep slopes, landslide prone soils, undermined areas due to former coal mine activities, and floodplains. To ensure that these conditions do not negatively impact proposed developments, projects may be subject to stormwater management plan review, floodplain review, and/or geotechnical report review.
