Hamilton County Drainage Board denies Jackson's Grant window‑well non‑enforcement, approves Ambleside maintenance agreement and several routine items

The Hamilton County Drainage Board on Aug. 25 denied a non‑enforcement request for a basement window well that would encroach into a regulated drain easement in the Jackson's Grant subdivision and approved a package of routine drainage business, including a maintenance agreement for a shared detention pond in Ambleside and a statement of basis for just compensation for a temporary easement on the Anchorage Drain project.

The denial concerned a proposed window well that would extend 3 feet into a 15‑foot regulated drain easement between lots in Jackson's Grant. A drainage board presenter recommended denial, saying, “we are recommending, denial of the non enforcement, for a couple reasons.” The presenter described the easement as an emergency flood route and said the window well is attached to the house foundation, which would make removal impractical if the county needed maintenance access.

John McKenzie, the home builder who addressed the board, said the excavation provided required basement egress and noted site constraints. “We have egress windows there, obviously required for emergency exit,” McKenzie said, and added that the top of the window wells would sit above the minimum flood protection grade. He also told the board that each lot has a 15‑foot easement so there is 30 feet between houses, and that the proposed 3‑foot encroachment would still leave 27 feet for access.

Board members said the combination of the easement's role as an emergency flood route and the fact that the wells are fixed to the foundation weighed against granting the non‑enforcement. A motion to deny the non‑enforcement passed by voice vote.

The board also approved a statement of basis to set just compensation for a temporary easement needed for the Anchorage Drain project. Staff told the board the valuation was reevaluated and reduced after earlier appraisals had anticipated removals that turned out not to be necessary; the board authorized staff to make an offer to the landowner based on that revised statement of basis.

On a separate, time‑sensitive matter, the board approved a maintenance agreement among the county, the Ambleside homeowners association and Lennar Development covering a shared detention pond that serves Ambleside and a 140 Sixth Street (Towne Road) parcel. The agreement expands an existing regulated‑drain pond onto Lennar property and specifies that both HOAs will share maintenance responsibilities. The board discussed enforcement language and billing for repairs; staff said the agreement contains a mechanism for one party to perform work and bill the others if necessary. The board set a 60‑day deadline for all parties to execute the agreement.

Other formal actions taken by the board included approval of minutes for July 28 and Aug. 11; approval of non‑enforcement items 1–12; signing of an executive‑session memorandum; and approval of a recorded agreement related to the Masthead Drain with the Phillips property owners. Staff provided construction and project updates on multiple drains, including Cool Creek, Mary Wilson, Hortonville, AF Ingram, William Lear (JS McCarty phase 3), West Arcadia, Emily Vessel, Elwood Wilson, and related arms of regulated drains. Staff said some work will wait until crops are out, that the last easement for the William Lear project was recently acquired through condemnation, and that several projects have mobilized or begun staking and excavation.

The board did not hold any hearings and had no spill or surety releases to report. Several items remain pending for future meetings, including outstanding ordinances requested from the county attorney’s office.
