Engineering

The mission of the Engineering Department is to furnish professional expertise to various Township Boards, Commissions, Township Manager, and other departments as necessary in order for those Boards and Departments to fulfill their charge under the Township's Home Rule Charter. Some examples of our advice concern engineering, stormwater management, stormwater runoff, sanitary sewers, flood plain management, and subdivision, and land development issues within Radnor Township. The Engineering Department is the liaison to the Planning Commission, Shade Tree Commission and the Environmental Advisory Council.

Grading Permits


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 Surfaces


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 Departm0ents.  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.
