Independence council approves Pines Third Edition plat, requires additional stormwater analysis

The Independence City Council voted Feb. 10 to approve the final plat for the Pines Third Edition and authorized the mayor to sign the accompanying resolution, while adding a requirement that the developer's engineer provide additional stormwater data and analysis to the city's reviewer before the detention-lot infrastructure is finally accepted.

Neighbors and engineers have disagreed about whether the basin, as constructed, meets city stormwater criteria after crews found an uncharted 30-inch pipe running through the detention area. The council's vote (six in favor, none recorded against on the final action) approved the plat but included language directing Crawford Engineering, the developer's engineer, to supply the information Fair Graham needs to confirm compliance; the council scheduled a March 2 work session to set the study's scope.

During the public-comment period a resident said she purchased flood insurance after heavy rains in July 2025 and asked who would be liable if properties flood. "I guess my concern is I'm just still concerned about the water that collects back there," the resident said, urging the council to address the problem. Tom Celestei, president of the Goldfinch Homeowners Association, told the council that 13 condos adjacent to Bluebird Court include older residents and basements and "I certainly urge a water study to be completed on this." The council acknowledged neighbors' concerns and the need for further analysis.

Planning staff described the site and said the newly proposed lots would route most new runoff to a detention basin on lot B. Staff and the developer's engineer said the basin was designed to detain the original nine-acre drainage area, but that a previously unknown 30-inch pipe has the effect of routing additional water through the basin. "We submitted a design and Fair Graham reviewed that design," a representative for Crawford Engineering said, adding that construction was completed in accordance with the plans and that the "pond will still function."

Fair Graham's reviewer, Sam, told the council the firm could not confirm the basin meets the city's stormwater-management standards without additional calculations, including delineation of the drainage area served by the 30-inch pipe and elevation data. "We just can't say with certainty...that what's out there currently as built will meet what the city's storm water management policy is," Sam said, recommending a targeted analysis of how much additional flow the 30-inch pipe contributes and whether the basin can detain the required events.

Council members and staff discussed technical options for mitigation — for example, partial orifice control or rerouting some flow — and noted trade-offs, including the risk that impeding the 30-inch pipe could create persistent water in the basin or require a larger detention design. Staff also said the developer granted the city an easement across lot B so city crews can access and address clogs or maintenance issues if necessary, while the homeowners association will maintain the detention lot under the approved resolution.

Under the resolution as amended, the council approved the final plat and the dedication of public improvements but excluded lot B (the detention basin) from dedication and acceptance; lot B will remain the responsibility of the homeowners association. The amendment added a requirement that Crawford Engineering provide the additional analyses and any required modifications be addressed by the developer in coordination with the city. The council directed staff to place the study-scope discussion on the March 2 work-session agenda.

The meeting record shows a roll-call approval for the amended resolution; staff said they will return with the proposed study scope and, if necessary, recommended modifications. With those directions in place, the council adjourned.

Next steps: staff will work with Fair Graham and Crawford Engineering to define the study scope and timeline for the additional stormwater analysis; the council set a March 2 work session to consider the scope.
