The Brighton City Council on July 1 approved acceptance of public improvements and public lands associated with the Marisol subdivision plan, a proposed mixed‑use development on about 155.59 acres north of East Bromley Lane.

City planning staff told council the subdivision plan lays out water, sewer, stormwater, road and park improvements to be constructed in five phases, and requires that public infrastructure be completed and accepted by the city before any vertical building permits are issued. Senior planner Emma Lane said, “The subdivision plan ensures that water dedication requirements will be met in accordance with the policies in effect at the time of final plat or site plan approval.”

The subdivision plan calls for connections to existing water and sewer lines, installation of nonpotable irrigation lines, on‑site stormwater detention in a pond at the site’s southeast corner, and construction or improvement of surrounding public roads including South 40 Fifth Avenue, Southern Street and East Bromley Lane. Staff described a north–south pedestrian trail under the overhead transmission lines and about 5.01 acres of proposed parkland (including a 3.89‑acre park and two pocket parks) and roughly 22.98 acres of open space.

Developer Ryan Carlson, representing Carlson Associates, told council the team purchased the property in 2024 and has coordinated with staff and external reviewers to refine the phasing and infrastructure design. Public works Director Greg Libri said Colorado Department of Transportation (CDOT) was consulted on improvements within CDOT right of way and that CDOT did not approve signalization at one early proposal; Libri added that the planned widening and new connections should provide alternate routes and relieve pressure at the existing frontage‑road intersection.

Councilmembers raised traffic and school‑drop‑off concerns at the frontage road and the Bromley Lane roundabout. Lane and Libri said traffic impact studies were performed and that final, more detailed traffic analyses and CDOT review will occur at the time of final plat and site development. Lane noted that some intersections and signals are warranted with specific phases and that the developer is required to design and construct the warranted signals and roundabout improvements as shown in the phasing plan.

Staff, the Development Review Committee and the planning commission recommended approval; planning commission unanimously approved the plan June 12. Councilmember Pulaski moved to approve the resolution accepting the public improvements; Councilmember Taddeo seconded. The council voted 6–0 (two absent) to approve the resolution.

If conditions in the subdivision plan change at final plat — for example, to meet park or open‑space credit requirements or CDOT requests — those changes must be reflected in the final plat process and in any required development agreements.
