Topeka planners present modest Land Use and Growth Management Plan edits, stress preserving urban growth area

City planning staff on Wednesday presented proposed edits to Topeka’s Land Use and Growth Management Plan and reiterated a policy stance against supporting urbanization outside the city limits.

The presentation led by Mike, a city planning staff member, summarized updated background data, changes to the executive summary and specific growth-management policies. Mike told the commission, “the policy does not support urbanization outside of the city, is what I would say.”

The update frames several measurable questions for the plan’s next review, including whether Topeka is gaining population share in Shawnee County and whether land use has become more compact. Staff reported the answer to both questions is currently no: “Is Topeka growing and capturing a greater percentage of population relative to Shawnee County? The answer to that 1 is no,” Mike said.

Why it matters: the plan’s policies guide annexation, subdivision and utility rules that shape where infrastructure and housing get built. Staff emphasized the plan still aims for fiscally responsible growth and to preserve land for future urban development rather than permitting scattered low-density lots that can lengthen infrastructure costs.

Key points from the presentation

- Urban growth area (UGA) and subdivision policy: Staff reminded commissioners the plan established a 20-acre minimum for lots intended to be planning-exempt inside the UGA and applies an 80/20 “largest-lot” split policy when plats are required. Where an owner seeks planning exemption inside the UGA, each resulting tract generally must be 20 acres and meet a minimum frontage and a depth‑to‑width ratio intended to avoid “piano key” lots. Outside the UGA, minimum tract sizes and frontage requirements are smaller (staff noted a minimum of 3 acres outside the UGA under current rules).

- Flexibility for very large tracts: staff described a proposed amendment to allow somewhat more than 20 percent of a very large parent tract to be developed in certain cases (e.g., the 20% allowance could be modestly higher for very large holdings), to reflect past practice on a few large parcels.

- Utilities and annexation: staff said subdivision and utility regulation changes and limits on sewer and water extensions are being enforced to curb sprawl. Mike noted the city has used unilateral annexation in recent years and said he will testify on a legislative bill the next day that would limit a city’s ability to unilaterally annex property.

- Neighborhood investment and transportation: staff pointed to continuing neighborhood investment programs (called Dreams 1 and Dreams 2 in the presentation) and cited a major sidewalk grant—approximately $25 million—planned to expand pedestrian infrastructure in areas that lack sidewalks. Staff also cited city and county sales-tax allocations that fund bikeways and other multimodal improvements.

Commissioner and public questions

Commissioners asked for clarifications about the tiered treatment of subdivisions, how the 80/20 split is applied (including the 300-foot frontage and 2:1 depth/width ratio inside the UGA), and whether the plan should say more about city–county coordination or zoning outside the city. Commissioner Copp urged the commission to consider whether the absence of city zoning in the extraterritorial area has driven low‑density development patterns. Staff responded that utilities and subdivision rules are the primary levers, and that zoning is “third on the list” of tools to manage fringe-area growth.

Next steps

Staff said it will return with additional sections of the plan at a future meeting (either next month or in May, depending on agenda load), will continue refining the proposed language on growth-management and land-use mapping, and will provide additional clarifications on use of data sources (staff said they would follow up on questions about use of the American Community Survey).
