Escondido planners approve six-lot Chestnut Drive subdivision despite neighbors’ drainage and tree concerns

The Escondido Planning Commission on June 9 unanimously approved Planning Commission Resolution 2026-05, clearing a tentative subdivision map (PL240309) for a six-lot residential subdivision at 500 Chestnut Street.

Alex Rangel, associate planner for Escondido’s planning services, told commissioners the project proposes six single-family lots on about 4.15 acres with two open-space lots and a private 36-foot access road maintained by a homeowners association. The staff presentation described lot sizes ranging from about 15,000 to 29,800 square feet, proposed retaining walls, grading exemptions for slopes down to 1.5:1, and a preliminary geotechnical investigation. Rangel said the project is identified in the city’s housing-element suitable sites inventory and that CEQA’s Class 32 infill exemption applies.

The project’s environmental and technical analysis, as summarized to the commission, included a no-net-loss review (the SSI presumed a buildout of 12 above-moderate units but the project proposes six), hydraulic calculations for drainage features designed for the 100-year storm, and geotechnical justification for the steeper slopes. Staff recommended adoption of Resolution 2026-05 subject to the standard conditions of approval.

Neighbors raised multiple concerns during the public-comment period. Debbie Arnold of 939 Hailrest questioned whether the proposed catch basin and new drainage swale would be large enough to handle existing runoff that currently flows into her driveway and whether the developer would encroach on her property. Michael Collins Frizz asked whether blasting or dynamite might be required in the rock and whether the city would require a bond to cover potential damage. Saber Hansen, who lives on a private road off Chestnut, asked about temporary access during construction, fence removal and dust or noise impacts that could affect health. Kristen Beller urged the commission to preserve the open space west of 941 Hailrest to protect a wildlife corridor including egrets. Tabitha Yanig asked for clearer renderings and assurances about erosion, dust controls and grading exemptions. Bill Listister stressed construction duration, loss of large trees and long-term noise implications.

Commissioners pressed staff on those points. Rangel and engineering staff said the design includes a concrete drainage swale and underground stormwater treatment sized using hydraulic calculations; staff stated the proposed drainage measures are adequate for the modeled storms. The planning staff noted the project will export roughly 10,000 cubic yards of material (the presentation referenced about 17,000 cubic yards of cut and 6,000 cubic yards of fill in total) and that best-management practices (BMPs) for dust, erosion control and construction hours are required and enforced through building and grading permits. On grading exemptions, staff said slopes below 2:1 trigger additional engineering review; the preliminary geotechnical report supported the proposed 1.5:1 slopes for the site. For trees, staff described replacement and protection rules for mature or protected trees and said a default 2:1 on-site replacement is applied when protection is not feasible.

Commissioners said the project’s small scale — six lots versus the SSI’s higher buildout — and staff’s technical responses weighed in favor of approval. Commissioner Stevie emphasized the constraints created by recent state housing laws and said projects that preserve larger lot sizes where possible can be a pragmatic outcome of that regulatory environment. After debate and clarifying questions, a motion to adopt Resolution 2026-05 passed unanimously; Chair Spear announced, “The vote is 7 to zero to approve Resolution number 2026-05.”

The approval is for the tentative map and preliminary grading; staff and the applicant will return with final maps, grading permits and subsequent plan checks that address construction-phase BMPs, final surveys to confirm property lines and any required tree replacement or protection measures. The planning staff also noted that final engineering, landscape and lot-level building plans will be reviewed as the project moves through the entitlement and permit stages.
