Timnath council approves Ladera South preliminary plat amid debate over North Reservoir open space and ownership

The Timnath Town Council unanimously approved Resolution 61 Series 2025 on Sept. 23 to accept the Ladera South Subdivision preliminary plat and set conditions for final plat review.

The preliminary plat covers the remaining unplatted land in the Ladera subdivision and as presented creates nine lots, two outlots (permanent open space) totaling about 74 acres in outlots overall, and four larger tracts reserved for future subdivision. Applicant Connell LLC described program elements for the North Reservoir open space (roughly 35 acres), including a roughly one-mile, 10-foot-wide multi-use concrete and decomposed-granite trail, benches, picnic tables, interpretive signage and pet-waste stations. Applicant Kirsten Starman said the reservoir area "is currently home to a decent stand of native grasses and wildflowers" and noted the limits that floodplain rules impose on permanent structures.

William Welch, Ladera infrastructure project manager, urged a lower-intensity, natural-area approach for the North Reservoir parcel, saying the area is largely inside the county floodway. "This entire open space is in the floodway," Welch told council, and he described prior local flood events that moved large rocks and damaged constructed trails in riparian corridors. Welch and the applicant said the southern reservoir open space is intended to be the more-active amenity area while the northern area should be treated as largely passive, native habitat.

Planning staff (Troy Jones) told council the preliminary-plat review criteria have been satisfied, but staff identified one outstanding item: the North Reservoir landscape plan submitted for preliminary review did not yet meet final-plat-level detail for code compliance. Staff proposed Condition 1 requiring that the final plat demonstrate compliance with the town's open-space design standards (cited in the application as section 5.7.0.6 subsection d) and that staff be allowed to work with the applicant on minor non-substantive modifications as part of final plat review.

Council and staff spent substantial time discussing ownership and maintenance. The applicant asked the council to designate the North open space as privately held and ultimately maintained by the Ladera Business Improvement District; town staff and the town attorney's office said a business improvement district is a governmental entity for these purposes and that ownership/maintenance should be documented during final plat and consistent with code. Staff said the town had previously indicated it did not want to take on maintenance responsibility for this particular open space.

Council members asked about timing and constraints tied to ongoing mining operations and reclamation on the southern portions of the site. Applicant representatives said mining and reclamation work must be completed before portions can be released for development; they expect phased releases and reclamation work through early next year for some areas, and longer-term reclamation for others.

The council approved the preliminary plat with a motion that includes the standard staff condition allowing staff to negotiate minor, non-substantive final-plat modifications and explicitly requiring final-plat compliance with the cited open-space provisions; the vote was 5-0.

What's next: the applicant will submit final-plat materials. Staff and applicant will resolve the North Reservoir landscape plan and ownership/maintenance details during final-plat review; mining reclamation and utility construction schedules will determine when specific tracts are ready for final plat and building permits.
