The Engineering Bureau provides design, drafting, survey, and inspection services for numerous projects undertaken by the City. In addition, the Bureau reviews all subdivision and land development plans for compliance with City ordinances and Codes, and maintains permanent records of the City’s infrastructure. Activities include design and inspection of all streets, utilities, bridges, public improvements, and permitting. The following is a more detailed description of these activities:
SUBDIVISION AND LAND DEVELOPMENT REVIEW
The process begins when a developer submits plans for subdivision or development. The plans are reviewed for compliance with applicable City ordinances, standards, and good engineering practices. Comments are made and the plans are revised. Once the plans are acceptable, the Planning Commission meets and approves the plans if appropriate. Next, we review shop drawings and cut-sheets for public improvements and prepare a cost estimate for the required financial security that the developer must post to ensure improvements are completed in accordance with the approved plan. City inspectors provide oversight of all activities within or affecting the Right-of-Way. As the project is completed, the improvements are inspected and financial security is released. As-built drawings are reviewed and filed at the completion.
The Engineering Bureau designs and implements numerous infrastructure projects each year including sanitary, storm, water and street reconstruction. Also included are annual projects to repair/replace sidewalk, trenches and street overlays. Design begins with the survey fieldwork followed by detailed design and drafting. Then, detailed specifications and a cost estimate are prepared. Any permits required from outside agencies are applied for and obtained. The construction project is then bid and awarded to a contractor. The survey crew typically provides the layout and the work by the contractor is inspected. Invoices and change orders are reviewed and processed until the projects is complete. Once completed, an as-built drawing is prepared and filed.
The Engineering Bureau reviews and signs-off or issues permits for all activities within or affecting the public Right-of-Way. This includes numerous types of permits such as: Driveways, curb, sidewalk, excavation, sewer and water connections, sprinklers, ROW encroachments, banners, fences, pools, utilities (gas, electric, phone, cable), sheds, dumpsters, and buildings.
For some larger projects, the City engages a consultant to perform the design. The City’s Project Engineer manages the project, reviewing design plans, schedule, payment invoices, and change order requests. When design is complete, construction is typically bid, awarded and inspected by the City.
