Decorah council approves amended school site plan and records land-use agreement with district

The Decorah City Council voted unanimously to approve an amended site plan for the Decorah Community School District and to record a land‑use agreement that formalizes continued community use of school grounds outside of school hours.

City staff told the council the recorded land‑use agreement is intended to memorialize prior understandings and terminate an earlier 2011 28E agreement related to the tennis courts. The motion to approve the land‑use agreement was moved by Councilmember Chisel and seconded by Councilmember Olson and passed on a roll‑call vote.

The council first voted to reconsider the earlier site‑plan decision before taking up the amended plan. Staff reviewed the amended packet (SP 101) and recommended approval contingent on five items: (1) an easement agreement for a storm‑sewer relocation with clear maintenance and replacement responsibilities; (2) corridor and replat adjustments to reconcile a corner of parking and the northeast tennis court with right‑of‑way lines; (3) conveying sidewalk easements where sidewalks straddle private property and including telecommunications easements where lines run under sidewalks; (4) a maintenance plan for on‑site detention and underground stormwater features; and (5) verification of fire‑protection infrastructure and compliance with state fire marshal standards.

Staff highlighted a materials and standards issue tied to the storm sewer. “The amended site plan includes HDPE pipe, which Iowa DOT standards only allow for diameters up to 48 inches. Current pipe is 54 inches,” staff said, flagging concerns about long‑term structural integrity and noting local contractors' skepticism about using HDPE at that size. Staff proposed that if the school insisted on HDPE, the easement agreement should assign responsibility for any resulting pipe failure to the district.

An engineering reviewer said he would examine the school’s stormwater calculations and that prior work on Hively Street had reduced watershed loading into the system. He recommended a structurally sound pipe (concrete or similar) where feasible to limit collapse risk and reduce long‑term maintenance.

Councilmember Chisel moved to approve the amended site plan with the five contingencies; Olson seconded. The roll call recorded aye votes from Chisel, Olson, Whittle, Neil, Parker and Olson (duplicates in the transcript recording were reconciled at roll call), and the motion carried. Council and staff praised the collaborative work with the school board and Superintendent Cronin and said outstanding technical details (easement language, final civil details and maintenance agreements) must be completed before building permits are issued.

What happens next: staff will work with the school district and its design team to finalize easement language, replat options and stormwater design details; the approved contingencies must be satisfied before the district can obtain building permits.
