Consultants press 'gateway neighborhood' strategy as Portsmouth master plan moves to public rollout

Consultants from UTIL presented a detailed update of Portsmouth’s comprehensive/master plan to the Planning Board on March 26, emphasizing a pivot from a downtown-centric approach toward five “gateway neighborhood centers” where the city would concentrate infrastructure and zoning changes to better deliver walkable mixed-use development and attainable housing.

Matthew Lutalma, UTIL principal, and Zoe Mueller, associate principal and project manager, said the draft plan incorporates extensive public engagement and new recommendations shaped by survey feedback, including a new goal on fiscal health and “managing growth” in ways that reflect community priorities. Mueller read a draft vision that calls for Portsmouth to “protect the places that anchor our shared identity and historic character, and invest in sustainability and resilience,” and to “expand attainable housing options for residents at every stage of life.”

Why it matters: The consultants framed gateway centers as a strategy to spread the benefits of a mature downtown — like walkability and fine-grain commercial fabric — into neighborhood corridors that are already attracting private investment. The approach pairs spatial priorities with targeted mobility upgrades (three transit routes currently serve these areas) and zoning adjustments intended to reduce barriers to housing types that match existing development patterns.

Key recommendations and evidence presented

- Spatial framework: The city is divided into three change categories — preserve, enhance, adapt — with the gateways identified as adaptation focus areas where public investment and regulatory changes would be concentrated. The consultants showed visual scenarios for the West End and the Islington corridor illustrating public-realm investment, tighter building frontage, and conversion of surface parking to street-facing uses.

- Mobility priorities: UTIL proposed a tiered bikeway network to link gateway centers with transit routes (identified as routes 43, 40 and 41 in the presentation) and recommended embedding the Seacoast greenway into neighborhood connections. They also urged intersection redesigns and micro-mobility management to support walking and cycling beyond downtown.

- Zoning and design: The team recommended simplifying district categories, clarifying intent in zoning text, and using design guidelines to achieve predictable quality without imposing overly burdensome discretionary review. They said a zoning memo will be provided to staff summarizing recommended changes (the consultants said they will not draft final ordinance text as part of this phase).

- SRB district analysis: A focused analysis of the single-residence B (SRB) district showed a large mismatch between existing lot patterns and current minimum lot-size rules — the consultants reported roughly two-thirds of lots are smaller than zoning allows. UTIL argued that allowing calibrated small multi-family and lot-size adjustments in SRB would align zoning with long-standing neighborhood form and enable incremental housing opportunities.

Board reaction and requests

Planning Board members generally welcomed the strategic pivot to gateway centers but pressed for more technical detail and clearer public messaging. Specific requests included:

- Data on infrastructure capacity and an order-of-magnitude estimate of capital costs for prioritized neighborhood investments, to inform trade-offs. - Quantification of how lot-size changes would translate into potential new dwelling units (a suggested way to make zoning changes tangible for homeowners). - Clarification in outreach strategy to reach school-age families (consultants said the April 22 evening open house is one milestone and that they will follow with targeted pop-ups and digital engagement).

On design, board members asked whether the plan will recommend stronger design guidance; consultants said the plan will recommend design guidelines and possible review processes while noting trade-offs in administrative burden.

Next steps

UTIL will circulate draft written recommendations to the board and internal stakeholders in early April and use board comments (requested by April 13) to refine materials before the April 22 public open house. The board did not take a vote on the plan itself at the March 26 meeting; the presentation was a milestone in the draft-to-public phase.
