Mona planning commission adopts private stormwater facility rule

The Mona Planning and Zoning Commission on July 2 adopted an amendment, listed as Ordinance 8-6, adding a private stormwater facility requirement to the Mona City Code. The ordinance requires developers to collect and maintain stormwater from subdivisions or businesses on their property using ponds, sumps or similar measures.

Commission members said the revision fills a gap in the code. Commissioners noted a recommended addition addressing design for a 100‑year storm that had been suggested by a commissioner identified as Jack and included in the draft prior to the vote. The commission opened a public hearing on the ordinances, discussed the recommended language and then voted to adopt the 8-6 private stormwater facility provision.

The ordinance was presented as a general rule requiring on-site retention and maintenance of stormwater infrastructure constructed by developers. The commission did not provide detailed engineering standards at the meeting beyond the referenced 100‑year storm recommendation; staff indicated external engineering review and inspections will be part of implementation on individual projects.

The meeting transcript does not provide a full roll-call vote tally for the ordinance; minutes record that a motion and second were made and the ordinance was accepted. The commission closed the related public hearing later in the meeting.

Planning staff advised that future development proposals will need to show stormwater collection and maintenance plans consistent with the new code language and that city inspectors/engineers will review site-specific installations.
