The Town of Morrisville owns, operates, and maintains public infrastructure systems for the benefit of its citizens. These systems include storm water, streets, sidewalks, greenways and other ancillary systems. The Town also imposes certain development standards for quality and appearance for the Town. Proper construction of these systems is needed to insure the safety of the citizens and save unnecessary expenditures of public funds, during both initial construction and future operation and maintenance. As such, the Engineering Design and Construction Manual has been created to provide minimum criteria for the design and construction of new infrastructure within the Town, while balancing the needs, rights, and expectations of private property owners, the citizens, and the general public. Additionally the Engineering Department has developed Administration Manual for site plan and construction drawing submittals.
Site Plan and Construction Drawing Review
The Engineering Department is responsible for the review of public infrastructure systems detailed in site plan and construction drawing submittals to verify that the applications meet Town specific design standards as specified within the Engineering Design & Construction Manual. Public infrastructure systems such as stormwater, streets, sidewalks, greenways and other ancillary systems are reviewed by the department for compliance with the design and construction standards to protect the safety of the citizens and minimize unnecessary future expenditures of public funds. The following information is provided in support of the development review and submittal process:
