Frequently Asked Questions

We are a traffic engineering firm that provides studies and analyses to support land development, public works, and transportation planning. Our services include Traffic Impact Analyses, Trip Generation Assessments, Safety Studies, Parking Assessments, and more.

Our office is in downtown Puyallup, Washington, and we serve cities, counties, and developers throughout the Pacific Northwest.

We partner with private developers, architects, civil engineers, and public agencies. Whether you’re submitting a development application or planning roadway improvements, our team provides the data and analysis required for approval.

A Traffic Impact Analysis evaluates how a proposed development will affect nearby roadways and intersections. It identifies potential traffic issues and recommends improvements to keep traffic flowing safely and efficiently.

Most jurisdictions require a TIA when a development reaches a certain size or generates a significant number of new trips. Requirements vary by city or county, so we confirm with the permitting agency before starting.

This study estimates the number of trips (vehicle, pedestrian, bicycle, transit) a project will generate. We use the Institute of Transportation Engineers (ITE) Trip Generation Manual and adjust the data to local conditions.

A Safety Study focuses on crash history, roadway design, and potential safety risks, while a TIA measures traffic operations and capacity. Some projects need both, depending on the scope.

Yes. Parking Assessments review code requirements, on-site supply, and expected demand to ensure projects provide adequate but not excessive parking.

You can contact us through our website, email at info@heathtraffic.com, or by phone at (253) 770-1401.

We typically need a site plan, land use description, and any requirements from the permitting agency. We’ll confirm the exact scope before starting.

Timelines depend on the project’s size and complexity. Smaller trip generation memos may take 1–2 weeks, while larger TIAs may require 4–6 weeks, especially if agency coordination is involved.

You’ll receive a professional report with text, tables, figures, and recommendations. Reports are formatted to meet agency requirements and can be submitted directly with your application.

While our office is based in Washington State, our engineers are also licensed in Oregon, Idaho, Montana, and Colarado, allowing us to provide services throughout the region. We are open to expanding into additional states as client needs arise.

Yes. We work directly with city and county staff to confirm scope, provide updates, and respond to questions during review. This helps avoid delays in the approval process.

We design our studies to match local and state requirements. Where flexibility exists, we present data-driven solutions that balance project goals with public safety.

Costs vary depending on project size, number of intersections studied, and agency requirements. We provide clear proposals with no hidden fees before beginning work.

Yes. Our engineers can present findings and answer questions at hearings, planning commission meetings, or public forums.

Yes, we do offer expert witness service. Our team has experience providing technical analysis, written reports, and testimony related to traffic engineering, transportation planning and safety evaluations. We support clients through all phases of the process, including depositions and public hearings.
