Council approves amendment shifting service-layer timing, escrow for Hunchke subdivision streets

The Common Council on June 17 approved an amendment to the Hunchke subdivision development agreement that changes how new streets are paved and who pays for the final service layer. Under the amended terms, the developer will still cover the full cost for a 3-inch asphalt street but will place a 2.5-inch binder lift initially; the city will hold escrow funds and place the final service layer when the subdivision reaches about 80% occupancy.

Why it matters: The city’s standard for finished residential streets moved from a 3-inch requirement written into the agreement to a 4-inch standard citywide and staff said the amendment better protects the service layer from damage during remaining construction. The amendment also instructs the developer to leave the binder lift in place until near the end of construction and creates an escrow mechanism to fund the service layer at city expense when the subdivision is substantially complete.

The Board of Public Works had recommended the amendment after discussing standard pavement practices and the risks of putting the final surface down too early. The board voted to recommend approval to council; council then approved the amendment unanimously. The amendment does not change the developer’s contractual obligation to pay the full 3-inch cost; it changes timing and creates the escrow to cover the city’s portion for completing the service layer at the 80% occupancy threshold.

No specific dollar amounts for the escrow or the expected timing for the city-funded final lift were provided at the meeting. Staff noted the change aims to reduce future repair costs caused by construction traffic and equipment while the subdivision is still active.
