Manvel council hears roadway impact-fee primer as staff eyes study

Consultants from Friese Nichols gave Manvel City Council a step-by-step briefing on roadway impact fees at a March 17 workshop, saying the charge would apply only to new development and would be used to pay the share of capital projects needed to serve growth over a 10-year planning horizon. "Impact fees are a financing tool that allows you to recoup the cost of a portion of growth that's happening in the next 10 years," said Ashida Rahman, Friese Nichols, in the presentation.

Rahman told council that roadway impact fees differ from the city's existing water and wastewater fees. Whereas water fees are assessed by meter size, roadway fees are based on the development's scale, type and service area and only fund capacity-increasing projects — for example, adding lanes to an arterial, not routine maintenance. She noted Texas Local Government Code requirements for notices, advisory committee review, and at least one public hearing for updates; roadway service areas are limited to a six-mile diameter and must be inside city limits.

The consultant outlined a required calculation sequence: adopt land-use assumptions, identify impact-fee-eligible capital projects from the city's thoroughfare plan, apply a 'rate credit' (either a statutory 50% reduction or a debt-service credit analysis) to avoid charging both ratepayers and developers for the same costs, then divide eligible costs by projected service-unit growth to set a per-unit fee. Rahman said impact-fee accounts may pay for engineering, land acquisition and debt service tied to eligible projects, but not routine operations and maintenance.

Council members pressed on how fees would interact with Municipal Utility Districts (MUDs) and whether developers could pass fees through to homebuyers. Staff and the consultant said the fee assessment occurs at planning and collection at permitting; developers often incorporate the cost into lot pricing or infrastructure financed through a MUD, but existing residents would not be retroactively charged. Several council members, including Mayor Davis, expressed interest in pursuing a study to prepare Manvel for continued growth while protecting existing taxpayers.

The presentation prompted council direction to staff to explore the study and potential funding sources; consultants estimated the study process would take about nine to ten months and would include public presentations to advisory committees and public hearings before any fee adoption.
