Prosper raised impact fees $7,747 per unit in one vote. Builders can see these coming.
In 2025, Prosper more than doubled its combined water and wastewater impact fee, from $6,643 to $14,390 per service unit. On a project with 100 equivalent service units, that single agenda item added $774,700 in cost. The previous rates had been in place since 2017, which is how these increases often arrive: years of no change, then a study, a hearing, and a new number.
The DFW fee map keeps moving
Irving adopted fees in April 2024 after a 20-month process, effective that July and assessed at building permit: $1,605 water, $1,088 wastewater, and $146 to $500 roadway per service unit for most uses, with materially higher amounts for multifamily and industrial categories. Cedar Hill adopted its ordinance in July 2024 at $1,059 per vehicle-mile for roadway, plus $4,489 water and $1,686 wastewater for a one-inch meter, with a 40% reduction for single-family and townhomes.
Fort Worth's June 2025 ordinance raised water and wastewater collection to 42.5% of the maximum assessable fee in year one and 45% starting October 2026. The city's example was $5,504 combined for a typical residential connection. Across 100 connections, that is $550,400 before roadway fees.
Classification and timing matter. Under Irving's table, the same service unit costs $3,193 for most uses but $5,618 for multifamily or warehouse, a $2,425 gap. Fort Worth locks the collection rate to the date the final plat is recorded, while Irving assesses at building permit.
Chapter 395 gives you rights with short fuses
Texas Local Government Code Chapter 395 requires land use assumptions, a capital improvements plan, advisory committee review, and public hearings. It also starts clocks. A suit contesting an adopted fee must be filed within 90 days. Written hearing notice by mail is available only to people who requested it by certified or registered mail within the previous two years.
If you build regularly in a city, file the certified-mail notice request. Agenda monitoring covers additional signals: the study contract showing an update is coming, the committee meeting where the recommended maximum appears, and the hearing where the fee is debated.
The fee study is the earliest tradable signal. It can appear as a consulting contract a year or more before anyone votes on rates.
Build a fee-change checklist before the hearing
Capture the existing collected fee, proposed maximum assessable fee, proposed collection percentage, service-unit definition, meter or land-use multiplier, roadway service area, and effective date. Then calculate the change for the project's actual mix. A per-unit headline can understate a warehouse, multifamily building, hotel, or large-meter connection when the schedule applies a different multiplier.
Identify the event that locks the rate. Depending on the jurisdiction and ordinance, that may be plat recordation, building permit, utility connection, or another milestone. Put that trigger beside the development schedule. A project that cannot accelerate construction may still be able to record a final plat before a higher collection percentage begins, but only the adopted ordinance and city guidance establish the answer.
Follow the process backward as well as forward. The consultant selection signals that assumptions and capital plans will be updated. Advisory committee materials show the calculated maximum and stakeholder recommendation. The hearing notice sets the public-comment date. The adoption item sets the rate and effective date. Minutes and the signed ordinance confirm what changed. Keeping that sequence together is more reliable than carrying a number from a presentation into a closing model. Recalculate the model after the signed schedule posts, then archive the superseded assumptions with their source dates.
What a watchlist does
AgendaWire polls monitored government sources every 15 minutes and classifies each item against the impact-fee topic, including fee studies, roadway and utility impact fees, capital recovery fees, and land use assumptions. Matches include a verbatim quote and the official source link.
Coverage currently includes Dallas City Council, Fort Worth City Council, and the commissioners courts of Dallas, Ellis, Kaufman, Parker, and Wise Counties. Fort Worth, the largest fee jurisdiction discussed here, is covered.
A watchlist is $40 per month for one topic and up to 20 custom keywords, with a 14-day free trial on the first. AgendaWire is source monitoring, not legal advice and not a substitute for Chapter 395's formal notice procedures.
Prosper's increase was $7,747 per service unit. The consulting work that produced it appeared in the public record before the vote.
