Residential Projects: As required by the City’s Subdivision Ordinance, as-built surveys are required for all storm drainage systems that are installed as part of residential or commercial subdivision infrastructure that is to be publicly-maintained. Storm drainage system as-built surveys must contain information regarding storm drainage constructed to the extents that correspond to the boundary of a recorded Subdivision Plat map. Storm drainage as-builts are to be sealed and signed by a Registered Land Surveyor.
Commercial Projects: The City's Post-Construction Ordinance requires as-built surveys for commercial projects. As-built certifications and surveys are also required for stormwater management facilities and Best Management Practices (BMPs) in subdivisions and commercial development sites or residential subdivisions. Most BMP as-builts need to be signed, sealed by both a Registered Land Surveyor and a Professional Engineer and must include a standard PE certification statement (see checklists below).
PROCESS & REQUIREMENTS
As-builts are to be submitted electronically in PDF format for City Engineering review, along with a completed Site Application. Visit the EPLAN webpage for more information on how to submit. For storm drainage as-builts associated with new street construction in subdivisions, the limits of the as-built survey must correspond to the limits of a recorded subdivision plat map. Be sure to include a PDF copy of the recorded Subdivision Plat map whose boundary contains the storm drainage being certified, or simply provide a reference to the Map Book and Page Number of the plat at the Register of Deeds.
The submitted information will be logged in for a detailed review by an Engineering reviewer. The review progress can be tracked in Accela Citizen Access on-line. 1st submittal As-built reviews are completed within 15 business days. If the as-built cannot be approved, any revisions that are required will be relayed to the applicant as redline comments on the As-built survey plan. Subsequent submittals also have a 15 business day turn-around time. Final approvals will be noted in Accela Citizen Access and an e-mail will be sent to the applicant to alert them of approval. The assigned Site Inspector will then be notified that a project can progress toward CO Hold Release for Commercial projects, and Bond Release and/or final Street Acceptance process for a Subdivision Street.
The Engineering team has prepared multiple checklists to aid in the preparation & review of as-built surveys. These are mainly a staff review tool, but it is encouraged that surveyors/engineers use the checklists as a guide to verify all required information is shown prior to submittal:
Detention (Surface and Underground)
Extended Dry Detention BMP
Sand Filter BMP
Wet Pond BMP
