How Eagle Mountain Handles Environmental Rules: A Practical Guide

By CityRuleLookup Editorial Team

Eagle Mountain maintains 111 local ordinances across all categories, and 5 of those deal specifically with environmental rules. Here is a breakdown of what the city actually requires, what is prohibited, and where Eagle Mountain falls on the strict-to-permissive spectrum compared to other cities.

Stormwater Management

Eagle Mountain charges a storm water utility fee on every developed parcel with impervious surface that contributes runoff, set under EMMC 13.75.070, and requires developers, property owners, and businesses to obtain a storm water permit from the city engineer before disturbing an acre or more of land, or less under specified conditions, per EMMC 13.75.100.

Key details: Fee basis: 1 ERU equals 4,000 sq ft impervious surface (13.75.070). Permit trigger: 1+ acre land disturbance (EMMC 13.75.100). Also triggers permit: Parking lots over one-tenth acre. Waiver: City engineer may waive in writing, no impact. Penalty: $50.00 to $5,000 per day (EMMC 13.75.170).

Violating the storm water chapter, including operating without a required storm water permit, is enforced under EMMC 13.75.160 through notices of violation, consent orders, show-cause hearings, and cease-and-desist orders, and is a Class C misdemeanor. EMMC 13.75.170 backs that with a civil fine of $50.00 to $5,000 per day, with each day of violation a separate offense, appealable to the city council within 15 days under EMMC 13.75.180.

Erosion Control

Eagle Mountain requires a sealed sediment and erosion control plan for every construction activity that disturbs land, under EMMC 13.75.110(H). The plan must be prepared by a registered professional engineer licensed in Utah, describe the site's erosion risks, and detail control measures, and any soil or debris tracked onto streets must be cleared by the end of the work day.

Key details: Plan required: For all construction land disturbance (13.75.110(H)). Certification: Sealed by a Utah licensed professional engineer. Street debris: Remove by end of work day. Late removal: Deemed a violation of the chapter. Penalty: $50.00 to $5,000 per day (EMMC 13.75.170).

Failing to remove sediment, soil, or debris tracked onto streets and public ways by the end of the work day is deemed a violation of EMMC Chapter 13.75. The city engineer enforces the erosion control plan requirement under EMMC 13.75.160 with notices of violation and stop-work orders, and EMMC 13.75.170 sets a civil fine of $50.00 to $5,000 per day, each day a separate violation, appealable to the city council within 15 days.

Defensible Space

Eagle Mountain requires property owners, including the city itself, homeowners, and HOAs, to maintain adequate defensible space as a fire break under applicable state fire ordinances. Construction and staging areas must independently maintain at least a 30-foot defensible space throughout construction. The rule sits in the subdivision improvement standards chapter, EMMC 15.10.360, and noncompliance exposes a project to a stop-work order.

Key details: Governing section: EMMC 15.10.360. Construction clearance: At least 30 feet around staging areas. General duty basis: Set by applicable state fire ordinances. Who must comply: City, homeowners, and HOAs. Enforcement: Stop-work order, bond forfeiture, or permit hold.

Noncompliance with the defensible-space standard falls under EMMC 15.10.340's general enforcement clause for Title 15: the city engineer or a designee may issue a stop-work order, hold building permits, or draw on the project's improvement bonds until the required 30-foot clearance around construction and staging areas is restored. There is no separate fine schedule specific to this section.

Flood Zones

Eagle Mountain regulates construction in flood-prone land under Chapter 15.105 EMMC, Flood Damage Prevention, which applies citywide even though FEMA has not mapped defined special flood hazard areas for the city. A development permit, meaning a building permit, is required to ensure any construction complies with the chapter, and violations carry criminal penalties.

Key details: Governing chapter: EMMC 15.105, Flood Damage Prevention. Applies to: All areas of Eagle Mountain that may flood. FEMA study relied on: Utah County Flood Insurance Study, June 19, 2020. Permit required: Development (building) permit before construction. Administrator: City building official as floodplain administrator.

Constructing, locating, extending, converting, or altering a structure or land without complying with Chapter 15.105 EMMC is a misdemeanor under EMMC 15.105.060, punishable by a fine of up to $1,000, up to 30 days in jail, or both, for each violation, plus the city's costs and expenses in the case. The floodplain administrator, the city building official, may also pursue any other lawful action to prevent or remedy noncompliance.

Flood Elevation Requirements

Eagle Mountain's floodplain administrator, the city building official, requires a building permit applicant to document the elevation of the lowest floor of new and substantially improved structures under EMMC 15.105.030(C). Where a variance allows a structure's lowest floor to sit below the base flood elevation, EMMC 15.105.040(J)(3) requires written notice of the added flood insurance risk.

Key details: Elevation data required: Lowest floor elevation relative to mean sea level. Who reviews it: Floodplain administrator (city building official). Variance below BFE: Requires written insurance-risk notice, EMMC 15.105.040(J)(3). Small-lot variance: Available on lots of one-half acre or less. Floodway limit: No variance if it raises base flood levels.

A structure built without documenting its lowest floor elevation as required by EMMC 15.105.030(C), or built below the base flood elevation without a variance and the written insurance-risk notice required by EMMC 15.105.040(J)(3), is out of compliance with Chapter 15.105 EMMC. EMMC 15.105.060 makes noncompliant construction a misdemeanor, fined up to $1,000, jailed up to 30 days, or both, per violation, plus the city's costs.

The Bottom Line

Eagle Mountain's environmental rules rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Eagle Mountain is broadly strict or permissive.
