Arapahoe County approves Eastgate general plan and water/sewer extension; special-district plan continued

Arapahoe County commissioners voted Feb. 11 to approve a general development plan for the 44-acre Eastgate site and to authorize a 10-41 permit extension allowing the City of Aurora to provide water and sewer to the project, while continuing consideration of the special district service plan to March 11 because one required notice was lacking.

The board’s approvals set a framework for a mixed-use planned unit development (PUD) that the applicants said would accommodate up to 1,000 residential units (capped in the GDP) and roughly 400,000 square feet of commercial and light-industrial space, including an industrial block visible from I‑70. The board approved the GDP (GDP 23-003) on a motion by Commissioner Baker, seconded by Commissioner Campbell; the 10-41 service extension (ASI 24-001) was approved on a motion by Commissioner Warren Gully, seconded by Commissioner Baker. The Eastgate special district service plan (SD 24-002) was continued to March 11, 2025, because one portion of the notice requirements did not meet the county’s standards.

Why this matters: the approvals move forward a large mixed-use project on the county’s border with the City of Aurora that applicants said will add housing variety and retail/industrial capacity. County staff and the applicants described substantial right-of-way dedication and infrastructure work needed to serve the site, and attached conditions intended to ensure utility preconditions, traffic mitigation and environmental safeguards are met before vertical construction.

The proposal and approvals Kat Hammer, senior planner with the county’s Public Works and Development Department, presented the applications as three related items: the Eastgate General Development Plan, a 10-41 application to extend domestic water and sewage systems, and a special district combined service-plan. Hammer told the board the planning commission held a public hearing on the applications and voted 7–0 to recommend approval of all three, and that referral comments had been addressed in staff’s recommended conditions.

Allison Hibbs of Plan West, representing the GDP applicant, said the rezoning request would convert about 44 acres from A‑1 agricultural/mixed use to a mixed-use PUD to create an “integrated mixed-use neighborhood” with a retail corridor on Monahan Road, light industrial near I‑70 and stepped residential density adjacent to existing neighborhoods. Hibbs said the GDP caps residential development at no more than 1,000 units and anticipates roughly 400,000 square feet of commercial space. She described a planned dedication of approximately 72 feet of right-of-way for Monahan Road widening and a proposed realignment of Colfax and East 12th Avenue through the site to improve connectivity.

Jeff Keeley of JMC Investments described the ASI 24-001 10-41 application and said the project team negotiated a territorial service agreement with the City of Aurora; Keeley said the applicants plan to tap Aurora’s existing or recently installed mains and that, after construction, operations and maintenance of the lines would transfer to Aurora. He told the board the site has no surface water or wetlands, that two on-site domestic wells would be abandoned when the development reaches those portions of the project, and that archaeological reviews identified sites that were not eligible for further protection.

Public comment and applicant responses A caller identifying herself as Jacqueline Berryman spoke on behalf of Sky Ranch residents and said the area lacks nearby grocery and fuel options and asked whether planning area PA‑1 (light industrial on the draft plan) could be rezoned or used for larger commercial uses such as big-box retail and theaters to provide amenities, jobs and tax base. Hibbs and staff responded that much of the permitted uses for the planning area overlap and that the concept plan contemplates retail and big-box–type uses adjacent to Monahan Road; staff noted final tenant mix will be market-driven and would be determined at later, more detailed permitting steps.

Conditions and next steps Staff recommended, and the board adopted, a set of conditions for both the GDP and the 10-41 approval. Key conditions recorded in the motions include: - Applicant must address Public Works and Development staff comments before final signatures and complete all preconditions for water and sanitation in the agreement with the City of Aurora prior to issuance of building permits for vertical construction. - Applicant must submit a transportation demand management (TDM) plan with the specific development application and coordinate with CDOT (Colorado Department of Transportation) on roadway concerns; the applicants agreed to contribute a prorated share of improvements at the I‑70/Monahan intersection as determined through the approval process. - Applicant must provide a spill prevention and response plan with final plats and administrative site plans, and must notify the county if any historical, archaeological or paleontological resources are discovered during construction. - Applicant must secure all necessary easements prior to site disturbance.

The board continued the Eastgate special district service-plan hearing to March 11, 2025, at 9:30 a.m. to allow the applicant to correct a deficiency in the public‑notice record; Kat Hammer signaled the county lacked one required portion of the notice for that specific item but had jurisdiction to move forward with the GDP and 10-41 hearings.

Context and board comments Commissioners asked about housing types and transit. The applicants said duplexes and townhomes are expected to be ownership units while multifamily buildings would likely be rental; the GDP includes a limit on single‑family detached housing to preserve a diversity of housing types. County and applicant representatives said RTD bus service does not currently reach this area; the applicants committed to a TDM study and internal multimodal and trail connections, and county commissioners referenced regional efforts to expand transit and shuttle services along the I‑70 corridor.

A planning-stage map presented to the board showed an airport noise contour affecting the northeastern portion of the site; staff and the applicant said that contour prohibits residential uses in that corner and that commercial or light industrial uses would be more appropriate there.

What the approvals do not do The board’s votes approved the GDP framework and the 10-41 extension subject to conditions; they do not approve final plats, specific development plans, site-level permits or any tenant-level commercial uses. Those details must come through subsequent Planning Commission or administrative reviews and permitting steps.

Votes at a glance (as recorded in the meeting) - GDP 23-003 (Eastgate General Development Plan): Mover – Commissioner Baker; Second – Commissioner Campbell; Outcome – approved (ayes recorded). Recorded motion includes conditions listed above. - ASI 24-001 (Eastgate 10-41 water/sewer extension): Mover – Commissioner Warren Gully; Second – Commissioner Baker; Outcome – approved (ayes recorded). Recorded motion includes conditions listed above. - SD 24-002 (Eastgate special district combined service plan): Mover – Commissioner Baker; Second – Commissioner Campbell; Outcome – continued to March 11, 2025, 9:30 a.m., due to a notice defect.

Ending The board’s approvals advance the Eastgate project into more detailed review and require the applicant to satisfy infrastructure preconditions, provide traffic and environmental mitigation plans and secure necessary easements before vertical construction. The special‑district service plan remain pending until the March 11 hearing; members of the public and adjacent neighborhoods will have additional opportunities to comment at later planning‑stage hearings and during the March continuation.
