Independence City Council approves the Pines' Third Edition plat, orders additional stormwater study

The Independence City Council voted 6–0 on Feb. 10 to approve the final plat for the Pines' Third Edition subdivision and authorized the mayor to sign the resolution, while adding a requirement that the developer provide additional stormwater analysis so the city can confirm the detention basin meets local criteria.

The action came after residents and engineers raised concerns about a previously uncharted 30-inch storm pipe discovered during construction that now passes through the detention basin footprint. Tom Celestei, president of the Goldfinch Homeowners Association, told the council the nearby condos "are going to be worrying about being flooded out" and urged a water study to protect older residents and basement units.

Why it matters: Council members and staff said the unexpected pipe could change how the basin detains water for smaller storms. Fair Graham, the city's independent reviewer, wrote that it could not "confirm the development complies with the city storm water management criteria" without additional data on the drainage area and elevations for the 30-inch pipe. Sam, an engineer with Fair Graham, told the council they needed to determine how much additional inflow comes from the south before certifying compliance.

What engineers said: A representative of Crawford Engineering, the developer's engineer, said construction was performed according to the submitted plans and that "the pond will still function," noting inlet and outlet capacities were preserved. Sam of Fair Graham countered: "we just can't say with certainty" that the built basin meets the city's stormwater policy until the drainage area and elevations for the 30-inch pipe are quantified.

Technical details: Council and staff described the system as having a 30-inch pipe that brings water from the south into the basin and a 24-inch controlled outlet to a ditch at Sixth Avenue, plus an emergency spillway. The basin was originally designed to detain a 100-year storm and release at a five-year rate, but staff and Fair Graham said the added inflow could mean the basin no longer provides detention for smaller (five- to 25-year) events unless modifications or further analysis are completed. Council members noted the basin now receives storm sewer flows from the new Bluebird Court work and that an easement on Lot B (the detention lot) was granted to the city to allow access if remediation is required.

Council response and next steps: Councilmembers amended the resolution to require that Crawford, as the developer's engineer, provide the additional information and analysis needed for Fair Graham to complete its review; if the review finds modifications are required, the developer must work with the city to address the concerns. The mayor and staff said the scope and cost of any further hydraulic study will be discussed at a March 2 work session. The motion to approve the plat and the amended resolution then passed on a roll-call vote.

Vote at a glance: The roll-call approval recorded yes votes from Hannah, Moore, Bradder, Maynor, Olaflin and Weber; one member (Applebe) was excused.

Public comment: In addition to Celestei’s remarks urging a study, another resident expressed ongoing worry about water collecting on Spruce Drive and said she had purchased flood insurance after heavy rains in July 2025. Council members acknowledged resident concerns and said the planned study could be expanded at the March work session to consider surrounding drainage areas.

The meeting adjourned after the vote. The council scheduled discussion of the study scope for its March 2 work session; if Fair Graham’s subsequent analysis finds the built system does not meet city stormwater criteria, the resolution requires the developer to work with the city to address identified issues.
