Emigration Canyon planning commission advances Title 19 review; fire-access, disturbance limits and bonding left for follow-up

Emigration Canyon Planning Commission met Feb. 13 to continue its multi‑month review of Title 19 site‑development standards, focusing on private road and driveway definitions, wildfire access standards, a proposed trail‑density bonus, limits of disturbance and bonding for grading permits. Staff and commissioners agreed to seek Unified Fire’s guidance before finalizing standards on road width and apparatus loading and to prepare visual demonstrations of disturbance limits for future meetings.

The meeting’s central work item was Title 19, the city’s site‑development chapter. Commissioners and staff discussed aligning Title 19 definitions with the engineering details in Title 14, clarifying whether features should be called "private roadways" or "private access roads," and whether to adopt Title 14’s more detailed engineering cross‑references. "We need to be consistent throughout the code with our definitions," Commissioner Jim (not specified) said, urging cross references to avoid confusion for applicants. Staff proposed using Title 14’s definitions for consistency and then adjusting as needed after the fire authority’s input.

Why it matters: the definitions determine which engineering standards apply (surface width, pavement/compaction and load capacity) and affect what private property owners must build or maintain. The commission flagged three specific technical points for follow up: the minimum unobstructed paved width (20–25 feet was debated), whether the surface must carry a 24‑ton vehicle as currently written, and whether a higher 80,000‑pound standard for “fire apparatus access road” applies in canyon settings.

On fire‑access standards, staff reported they had contacted Unified Fire. "The answer to both of these questions is the 2006 Utah Wildland Urban Interface code," said Matt (staff member), quoting the Unified Fire contact’s response, and added that Unified Fire bases its approach on the International Fire Code. Commissioners noted an apparent discrepancy between the 2006 WUI reference and the 2021 International Fire Code and asked staff to confirm which current code the fire authority will enforce. Commissioners repeatedly requested Unified Fire or its plan reviewer, Sean Peterson, attend a future meeting to explain minimum widths, surface composition and the required load capacity of access roads for the canyon.

The commission also debated how prescriptive the ordinance should be about pavement types and subsurface road base. Staff said the traffic engineer and the new MSD engineering hires (a traffic engineer onboarded recently) should review the technical standards; commissioners agreed to wait for Unified Fire and the traffic engineer before changing numeric standards.

Trail density bonus and master plan coordination: Staff presented a draft framework for a density bonus tied to developer contributions to trails — a metric staff estimated as roughly $15,000 per additional unit in a candidate formula. Commissioners supported the concept in principle but agreed to defer any ordinance language until the city finalizes a trails master plan and public engagement occurs. "We should temporarily remove it until we have that master plan," one commissioner said; several members added that any required trail work should be part of an adopted plan and that the city must account for long‑term maintenance costs.

Limits of disturbance (LOD): Staff outlined a proposed approach to limit disturbance by lot size with concrete thresholds — for example, minimum allowances of 3,000 sq. ft. up to maximums near 10,000 sq. ft. or 40% of a lot, depending on parcel area. Commissioners raised canyon‑specific concerns: many lots include steep, largely unbuildable acreage, so a simple percent‑of‑lot rule can permit excessive clearing within the actually buildable area. Suggestions included excluding very steep slopes from the calculable area, excluding long private access drives from the disturbance total, and retaining a director approval path for unusual cases. Commissioners asked staff to prepare demonstration diagrams for several representative lot sizes and to show how setbacks, stream corridors, wetland buffers and slope limits would affect allowed disturbance.

Bonding and grading permits: Commissioners discussed the Glassman property as a case study where grading occurred and retaining walls planned but not constructed. Participants said the grading permit and erosion controls (a Stormwater Pollution Prevention Plan) had been inspected, but the retaining walls were not completed; commissioners worried the eventual cost to repair a slide or downstream water contamination could exceed the original work cost. Staff said bonding policy may need procedural fixes rather than only code changes — for example, requiring a bond when a grading permit is issued without an associated building permit or when engineered retaining structures are part of an approved grading plan. The commission asked staff and MSD stormwater/engineering to research possible bonding thresholds and return with options.

Process and next steps: The commission directed staff to invite Unified Fire (or its plan reviewer Sean Peterson) to a future session to explain wildland‑urban interface and apparatus access requirements, to have the new traffic engineer review roadway‑width and loading metrics, and to prepare visual demonstrations of limits‑of‑disturbance scenarios. Staff said they expect three to four additional working sessions to finish the review. Matt (staff member) said he will copy relevant parties and attempt to schedule the fire reviewer for the next meeting.

Votes at a glance: The only formal votes recorded during the meeting were procedural. Commissioners approved the Jan. 9 meeting minutes with modifications (motion carried by voice vote; unanimous) and later approved a motion to adjourn (voice vote).
