Normally all applications for construction projects must apply for a grading permit. This permit is required if the footprint of any impervious surface is being expanded and/or replaced. A grading permit must be approved before a building permit application is accepted by the Community Development Department.
Impervious surface is any surface that prevents the infiltration of water into the ground. Impervious surfaces include, but are not limited to, streets, sidewalks, pavements, driveway areas, or roofs. Any surface designed to be gravel or crushed stone shall be regarded as impervious surfaces.
Earth moving in any instance also institutes the necessity of a grading permit.
Subdivision and Land Development (SALDO) All requests for subdivision and land development in Radnor are processed through the Engineering Department and reviewed for compliance with the Township's zoning code and subdivision ordinance by the Community Development, Public Works, and Engineering Departments. Their findings are considered by the Planning Commission, which also evaluates projects' adherence to the comprehensive land use plan. The Board of Commissioners then reviews the recommendations of staff and Planning Commission members before deciding to approve or reject a proposal.
