Planning staff proposes targeted rewrite of major‑street setback rules to reduce arbitrary 50‑foot requirement

Planning staff on July 15 asked the Marshfield Plan Commission to consider a targeted amendment to the city’s major‑street setback requirements that would remove the blanket 50‑foot setback for many streets and instead apply an approach tied to actual right‑of‑way needs.

Bryce Henbrook, the city planner and the item’s presenter, told commissioners the current rule uses a 2007 functional‑classification map to identify “major streets,” which produces inconsistent results when compared to the updated 2017 comprehensive plan. Henbrook said the result has been an “arbitrary requirement” that applies a 50‑foot setback along many streets where the city does not need additional right‑of‑way.

Henbrook said staff’s proposed approach replaces the map blanket with a calibrated method: remove major arterials that already meet required widths (for example Central Avenue and Veterans Parkway) from the requirement and apply an adjusted setback (the property’s underlying zoning setback plus 10 feet) only on corridors where the city’s Chapter 19 subdivision standards show additional right‑of‑way is needed. He said the city could continue to accept right‑of‑way dedication through certified survey maps rather than initiating involuntary acquisitions.

“We're not looking to acquire any, you know, property at this time,” Henbrook told the commission, noting that dedications typically occur during lot splits or certified survey map filings. He said the proposed change aims to reduce the number of nonconforming buildings created when right‑of‑way needs are adjusted.

What staff looked at

- Functional‑classification confusion: staff identified inconsistencies between the 2007 map that the code references and the 2017 comprehensive plan classifications. - Right‑of‑way inventory: staff mapped streets where Chapter 19 standards indicate additional right‑of‑way may be necessary (examples include Peach Street, Oak Avenue and Lincoln Avenue) and proposed reserving increased setbacks only for those segments. - Applicability: downtown mixed‑use (DMU) and urban mixed‑use (UMU) districts would remain exempt (0‑foot setback) where the code already provides for that form.

Commission response and next steps

Commissioners asked for clarification about nonconforming structures, dedications and whether existing dedications would be re‑subject to any new requirement. Henbrook said the proposed approach would not require immediate acquisitions and that dedications already recorded through CSMs would satisfy future right‑of‑way needs; he said staff can add clarifying language if the commission desires.

The commission voted to direct staff to prepare a formal text amendment and return with draft language and a staff report at a future meeting. The motion passed without amendment.

Why it matters

The change would reduce the number of properties rendered nonconforming by broad application of a 50‑foot setback and limit the city’s larger setbacks to corridors where future roadway expansion or standardization actually requires additional right‑of‑way. That may reduce permitting friction for property owners along corridors that are not planned for widening.

Meeting context

The discussion grew out of prior internal reviews dating to 2020 and was prompted by recent development review activity (for example, a seven‑foot dedication on McMillan Avenue accepted through a CSM). The commission asked staff to return with concrete text and clarifying edits to the UMU/DMU language.
