Check permit triggers early in project planning to avoid delays.

Stormwater Management Requirements

Key requirements typically include retention, detention, water quality treatment, erosion and sediment control during construction, and long-term maintenance of stormwater facilities. Project-specific thresholds and design standards are set by the City and referenced design manuals.

  • Design standards and manuals: follow City-adopted stormwater design criteria.
  • Permits: development and construction stormwater permits are required when land-disturbing activity meets City thresholds.
  • Maintenance: perpetual maintenance obligations for on-site storm facilities are assigned to owners or homeowner associations.
Most small maintenance projects still require erosion controls during work.

Sewer Connection Requirements

Private sewer connections to the City system must meet construction standards, be inspected, and in many cases require a permit or authorization from Utilities. Connection fees or capacity charges may apply. Contractors typically must use licensed plumbers and schedule inspections with the City. Wastewater and Sewer[2]

  • Inspections: schedule and pass required sewer lateral inspections prior to cover.
  • Fees: connection or capacity fees may be assessed at time of permit issuance.

The Utilities department conducts inspections during construction and may require post-construction certification of installed stormwater and sewer facilities. Property owners are responsible for ongoing maintenance and for responding to City notices of violation.
