Development Review

 Home / Departments / Planning Department / Development Review

Delaware County planners provide advisory PA Act 247 reviews of proposed development, zoning amendments, and ordinances for County municipalities.

The Planning Department (DCPD) strives to improve the quality of development throughout the County by conducting advisory reviews of all land developments, subdivisions, and ordinances proposed in Delaware County. Staff planners present their reviews to the Delaware County Planning Commission at its monthly meetings, where official recommendations are made. In addition, Development Review staff provide technical assistance to municipalities and developers on site planning and ordinance compliance issues.
