Water district proposes lower impact fee for ultra‑water‑efficient homes, drawing city questions on enforcement and equity

A water district representative on April 16 described a voluntary “ultra water efficient” development standard that would let developers pay a smaller regional water impact fee if new single‑family homes reduce potable water use roughly one‑third compared with current practice. The district official said the program would be optional in city limits and mandatory where the district is the expected retail water provider for unincorporated areas.

The district representative, identified in the meeting as Doug, told the Hurricane City Council and planning commissioners the program is not a new code or regulation and “would work in the exact same way with your planning commission and with all the codes and standards and processes you already have in place.” He said the reduced impact fee would reflect the smaller expected burden on regional treatment and conveyance infrastructure and could be “a third less than whatever the standard impact fee winds up being” after the current impact‑fee study is complete.

Why it matters: Impact fees fund regional water infrastructure such as treatment plants, pipelines and recycled water projects. Council members pressed the district on whether a discounted fee is appropriate in unincorporated county areas where infrastructure needs can be greater, and asked how the district would prevent the discount from shifting costs onto existing customers.

Key details from the presentation and discussion

- Target and mechanics: The program aims to encourage new single‑family homes that use about 33% less water than the district’s current standard. The district would create a new fee class for developments meeting the standard; developers or cities that approve projects meeting the standard could pay the lower fee when they connect to the regional system.

- Where it applies: Doug said the discount would be available “either place, a city or within unincorporated,” but clarified it would be mandatory in county areas where the district is expected to serve as retail provider and voluntary inside municipal boundaries.

- Performance and protections: To ensure homes perform to the standard, the district would require developers of subdivisions to create homeowners associations (HOAs) that include the landscaping and irrigation standards in CC&Rs and would implement surcharge mechanisms similar to those now used for homes that have only culinary (potable) water indoors and separate irrigation supplies outdoors.

- Landscaping and amenities: The draft standard would generally limit irrigated private yards to roughly 2,000 square feet of drip‑irrigated planting adjacent to homes on typical 6,000‑square‑foot lots, discourage private swimming pools (allowing shared community pools instead), permit freestanding spas up to 100 square feet and allow 25‑square‑foot ornamental water features already in code. The standard also envisions community parks sized so that a neighborhood of 15 houses could provide about 1,500 square feet of active recreation area.

- Softener and wastewater concerns: The district asked builders to avoid offering salt‑based water softeners as part of buyer packages because salt brine is a key contaminant for downstream water recycling facilities. The district suggested alternatives such as potassium‑based systems or template assisted crystallization, citing research from Arizona State University as an example.

Council concerns and staff clarifications

Council and planning commissioners repeatedly pressed the district on several points: whether the discount is an incentive if the program will be mandatory in county service areas; whether regional infrastructure costs actually decline for low‑use homes that still require pipelines and treatment; how the district will reconcile municipal requirements such as required secondary systems; and whether the reduced fee would meaningfully lower the purchase price for new homes.

- Fee examples: The district said the prior single‑family impact fee was about $13,500 (scaled by lot size), and home builders reported secondary‑system hookups cost roughly $3,500 per household. The district told the council it would seek to price the new fee commensurate with the expected reduction in regional demand.

- Surcharges and existing customers: Doug stressed the district would implement surcharges and monitoring to ensure homes actually meet the performance standard. He also clarified a billing concern for long‑time homeowners: the district’s surcharge for homes built before 2023 is currently $1 per 1,000 gallons for usage above 35,000 gallons in a month; the district calculated that even very high month‑to‑month use yields relatively modest monthly surcharge amounts.

- Municipal discretion: The district emphasized it would not substitute for city land‑use review or require cities to change ordinances. Cities retain discretion to require parks, secondary systems or other features through their planning and subdivision processes; the district’s role would be to offer an alternate fee for developments that meet its water‑use standard.

No final action taken

The discussion was informational and part of outreach while an impact‑fee study is under way. No ordinance or fee schedule was adopted; the district indicated it will continue outreach with cities and developers, refine the standard and incorporate feedback before any formal proposal returns for local action.

Ending

City officials said they will continue to review the district’s draft, ask staff to coordinate on implementation details and raise questions at future meetings about how to protect municipal interests — including equitable cost allocation and enforceability — before any fee changes are adopted.
