Why this matters for planning
Sterling Heights adopted its own Stormwater Management Standards, effective May 17, 2023, and prohibits illicit discharges into the city storm sewer. The city also requires a floodplain development permit for work proposed within mapped flood hazard areas -- both relevant to moisture conditions around foundations, crawl spaces, and grading.
Official sources

Nothing citywide tells you a specific lot's flood zone, historic status, permit needs, soil type, or what's hidden in the construction. Get those confirmed by the right authority and your provider before work starts.
