Neighbors press Laguna Beach board over Zelle Drive excavation, board approves project with limits

The Laguna Beach Design Review Board voted 4‑1 June 12 to approve a revised design for a new single‑family residence and related site work at 2840 Zelle Drive, but not before an extended hearing that centered on neighbor concerns about deep excavation and privacy.

At issue: The applicant sought approval for a new multi‑level home with attached garage, an upper‑level deck, retaining walls and an in‑ground spa. Neighbors said the project still required significant excavation — roughly 900–1,000 cubic yards by the participants’ estimates — into hard bedrock close to adjacent foundations. Residents and a consulting engineer warned of vibration, dust and potential structural damage without careful monitoring; they asked the board to require a smaller building program or additional site studies.

Why it matters: The property sits on a steep hillside with limited usable yard area; the design’s below‑grade garage and patio areas require rock removal near neighboring foundations. The scale of excavation and the nearby residences made this more than a routine design review; board members weighed geotechnical risk, neighborhood compatibility and the extent of outdoor living areas proposed on the west side of the lot.

Key points from the hearing - Neighbors’ objections: Multiple neighbors — including 2849 Chelan/Chalon and 2850 Zelle Drive residents — testified that the revised plans still demanded heavy excavation near existing homes, could cause structural damage and produce substantial truck traffic through neighborhood streets. They asked the board to require a bond for potential damage and to reduce the amount of sandstone removal. - Applicant response: Architect David Parker and the project geologist told the board they expected the bedrock to be “rippable” with heavy equipment rather than requiring blasting. The applicant’s geotechnical engineer recommended pre‑construction condition assessments and vibration monitoring during grading and offered mitigation strategies if vibration readings exceeded thresholds. The team agreed on the record to provide monitoring and to work with building‑department requirements for shoring and protection methods. - Board conditions and redlines: To address neighbor concerns, the board approved the project only after the applicant agreed to several on‑the‑record changes: (1) reduce the rear patio usable concrete area by following a redline (staff to verify — described during the hearing as roughly a 20–30 percent reduction in usable patio area); (2) remove a fence at the rear property line and replace it with a hedge with a capped height (privet hedge noted in plans, to be maintained below the eave/ridge per board direction); (3) adopt the applicant’s geotechnical recommendations including pre‑construction condition surveys and vibration monitoring during grading; (4) reduce exterior landscape lighting (applicant agreed to cut numbers roughly in half and to change recessed soffit fixtures to narrower‑spread, low‑glare models); and (5) confirm retaining‑wall locations and minor plan adjustments per staff redline.

Board deliberations: Board members split on risk tolerance. One member said the applicant’s geotechnical memo left too much ‘‘unlikely’’ risk and opposed approval absent removing the deep subterranean work; other members emphasized that similar excavation has been accomplished elsewhere in Laguna Beach, that the applicant accepted monitoring and mitigation, and that revised plans reduced mass and grading. The motion passed 4‑1 (Bauta, Coveney, Weil, Gannon in favor; Gibbs opposed).

Clarifying details recorded on the record - Applicant/engineer: recommended preconstruction surveys and vibration monitoring; reported that no blasting is anticipated and that experienced operators and equipment reduce the likelihood of structural damage. - Excavation estimate discussed by neighbors: approximately 973 cubic yards (neighbors’ figure; applicant noted reductions from prior submittals). The exact final export quantity will be determined at building‑permit stage. - Landscaping: hedge specified as privet; board required maximum mature heights not to exceed the roof eave/ridge in critical view corridors.

Next steps: Staff must confirm the applicant’s redline changes and update the resolution text; the building department will require submittal of the geotechnical monitoring plan, vibration limits and a shoring plan (if required) before issuing grading or foundation permits. The approval is appealable under the city’s 14‑day appeal period.

Quotes (on the record) - “If appropriate equipment and experienced operators and contractors perform the excavations, it is unlikely that such vibrations will be sufficient to promote structural damage to the vicinity,” the applicant’s geotechnical memo said (applicant presentation). - On public risk, a neighbor’s engineering memo said: “This excavation appears to be into hard bedrock…Damage to the adjacent home is very likely,” and requested additional geotechnical work before approval (neighbor comment).

Ending: The board balanced neighborhood risk concerns and professional mitigation measures; it approved the project with explicit, on‑the‑record modifications to reduce patio area, cap landscape heights and require monitoring during grading.
