Ada County hears hours of opposition to Shaw (Shadow) Valley planned community; decision tabled

The Ada County Board of Commissioners on Nov. 12 heard a detailed staff presentation and more than an hour of public testimony on a proposal to establish the Shaw (sometimes referenced in materials as "Shadow") Valley planned community, then voted to close the record and table the matter to Dec. 16 for further review.

Staff planner Brent Danielson told the board the two‑step request (a comprehensive plan map and text amendment now, with a later implementation plan and development agreement) would designate about 560 acres for a mixed residential community east and west of Highway 55 and allow up to roughly 395 homes on the east side and 89 on the west side. Danielson said staff recommends approval, subject to agency approvals and conditions, and explained how the applicant proposes to supply water and wastewater: "Pauble water will be provided to the development through a stand alone public water system utilizing on‑site wells, which will require approval from the Idaho Department of Water Resources," and the applicant plans a community wastewater treatment plant that would treat effluent for reuse in golf‑course irrigation and require Idaho DEQ approval.

Why it matters

Neighbors pressed three central concerns: groundwater and well impacts, safety and capacity of Highway 55 and local access roads (notably Spring Creek Way), and wildfire risk in the foothills. Several residents said Spring Creek Way is narrow, steep and already dangerous during summer weekends and argued that the proposed density (the east side’s ~306 homes on ~118 acres excluding the golf course) would overwhelm local roads long before off‑site mitigations could be built. Rachel Artner, who organized an online petition opposing the rezone, said: "We had over 1,070 digital signatures in opposition — this is not a blank slate of land; people have lived here for 40‑50 years and this will change the character of our neighborhood."

Applicant response and developer commitments

Developer Larry Keim, speaking for the golf course owner, framed the proposal as a way to preserve and fund long‑term maintenance of the existing golf course while adding housing. Keim said the project team is pursuing municipal water rights and an on‑site membrane‑based wastewater plant that would return "about 95%" of treated water to the irrigation system and argued the design includes open‑space buffers and wildlife mitigation. "We will be building our own private municipal water system," he told the board, describing negotiated settlement agreements with some neighbors and a commitment to run a water line through vulnerable neighborhoods so residents would have an option to connect in the unlikely event their private wells fail.

Two institutional responses caught commissioners’ attention. The Planning & Zoning Commission recommended denial, citing traffic impacts and neighborhood character; staff recommended approval, saying many concerns can be addressed later in the implementation plan. Boise Hunter Homes — a nearby developer whose Dry Creek Ranch project funded extensive local road improvements — said it would support approval only if Shadow Valley reimbursed a share of previously constructed transportation improvements. Josh Leonard, counsel for Boise Hunter Homes, told the board: "Using the number of homes proposed, we determined Shadow Valley's 395 proposed homes comprise 18% of the new homes that will use the transportation improvements paid for by Boise Hunter Homes, and we ask that the board require reimbursement." He proposed a reimbursement figure and asked the board not to defer that question to ACHD or ITD.

Board action and next steps

After several hours of public testimony — with dozens of residents describing safety and water worries, and the applicant answering questions about infrastructure and mitigation — commissioners said they needed more time to review the voluminous record and legal questions. The board closed the public record and unanimously voted to table the application to the Ada County open business meeting on Dec. 16, 2025, with no new evidence to be accepted before that date. If the board advances the comprehensive plan designation at that time, a second step — the implementation plan with zoning, development agreement, detailed infrastructure plans and agency approvals — would follow and require additional public hearings.

The county’s next procedural step is the Dec. 16 open business meeting, when commissioners said they will revisit the record and may vote to adopt the comprehensive plan amendment or take other action.
