Board approves 317-unit Castle View multifamily project with reduced parkland fee and conditions

The Douglas County Board of County Commissioners on May 27 approved a use-by-special-review (USR) allowing a 317-unit multifamily project on about 12.6 acres near the I‑25/E‑470/County Line Road interchange (project file US2024-009).

The Board approved the Castle View Filing 1, second amendment (lots 1A and 2A) with nine conditions after the applicant and staff negotiated a reduced cash-in-lieu parkland payment. Staff’s standard calculation produced a land-equivalent park obligation that would exceed the site area; the applicant proposed an alternative formula relying on lower expected persons-per-unit and credit for on-site private recreational amenities.

Why it matters: The site is in the C (Commercial) zoning district and adjacent to existing multifamily housing, I‑25, E‑470 and the County Line light-rail/RTD station; it therefore raises questions of noise mitigation, parking demand, multimodal access and whether privately provided amenities can substitute for public parkland dedication.

Key facts - Proposal: 317 multifamily units on 12.6 acres in C Commercial zoning; private amenities include a clubhouse, fitness center, pool, dog park and a game lawn. - Parkland: Under the county’s default Article 10 formula the site’s parkland cash-in-lieu would have been approximately $9.8 million (and a land dedication larger than the site). Staff and the applicant agreed a credit for prior payments on the property and on-site amenities reduced the proposed cash-in-lieu to $1.9 million in the staff analysis; during the hearing the applicant offered a revised proposal of about $2.7 million and the board accepted the application with the conditions presented. - Parking: The county’s standard parking requirement is two spaces per unit; the applicant proposed a reduced parking ratio of 1.8 spaces per unit supported by field counts at comparable developments and was granted an alternative parking ratio by the community development director (582 spaces proposed vs. 643 required under 2/ unit). - Airport and noise: The property lies within the Centennial Airport review area. The applicant agreed to record a navigation (avigation) easement for the Arapahoe County Public Airport Authority. An acoustical consultant reported interior noise modeling at or below the 45 DNL standard advocated by airport reviewers.

Public review and staff analysis Staff presented referral comments on traffic, drainage and engineering matters and noted the Centennial Airport Authority’s request for a navigation easement; the FAA offered no objection to building heights. The Planning Commission recommended approval (8–0). Two public comments to the Planning Commission opposed residential uses near the airport due to safety and noise concerns; those concerns were addressed in part by the applicant’s noise attenuation design and the proposed recorded avigation easement.

Board discussion focused heavily on the parkland calculation and precedent. Commissioners said they were reluctant to undercut parks policy broadly but were also mindful of project feasibility and the county’s interest in adding workforce housing near transit and regional employment centers. Commissioner discussion concluded with an applicant concession during a recess: the developer revised its cash-in-lieu proposal to a reduced payment of roughly $2.7 million (after credits for prior payments and on-site amenities), and the board accepted the application with the nine staff conditions.

Formal action and conditions The board approved the USR and required the applicant to complete nine conditions before recordation or building permits. Key conditions (summary): approval of required USR improvements and public-improvements agreements; securing private recreational amenities via the USR improvements agreement; recording a navigation easement to Arapahoe County Public Airport Authority; recordation of required drainage/utility/sidewalk easements and vacating certain existing storm drainage easements; payment of cash in lieu of 2.801 acres of parkland (the staff figure) in an amount described in the staff packet or as otherwise modified by the board’s acceptance of the applicant’s proposal; payment to Douglas County School District for cash in lieu of land dedication; technical corrections to the plan exhibit; and the standard reliance-on-commitments condition.

Noise and safety The applicant retained an acoustician who testified the proposed building materials and upgraded wall/roof/window assemblies should result in interior noise levels below airport/noise thresholds. "I did the analysis. I did modeling, and we were below 45 d d b a d and l inside the apartment," the acoustician said on the record. The applicant also proposed a 10‑foot noise wall adjacent to outdoor amenity areas to reduce ambient highway noise at the pool and dog‑park spaces.

Voting and next steps The motion to approve Castle View Filing 1, Second Amendment (US2024-009) with nine conditions passed unanimously after the applicant’s revised parkland payment was added to the record. The applicant confirmed it will finalize and record the required agreements and easements as a condition of final plan approval; building permits cannot proceed until the listed conditions are satisfied.
