Research first
Standing water that penetrates the base weakens the material supporting the pavement surface, leading to cracking, potholes, and premature failure that resurfacing alone won't fix.
Recurring cracking, potholes, or ponding in the same spot after repairs are common signs. Ask a contractor to evaluate grading and drainage, not just patch the visible surface damage.
It can, depending on the scope and local jurisdiction, especially for changes that affect stormwater flow. Ask the contractor what permitting they expect to need.
