(Alameda County Super. Ct. No. RG08396845). Frank Roesch, Judge.
The opinion of the court was delivered by: Jones, P.J.
CERTIFIED FOR PUBLICATION
Appellants Fred and D'Arcy Tomlinson (the Tomlinsons) filed a petition for a writ of administrative mandate (Code Civ. Proc., § 1094.5), challenging the decision of respondent County of Alameda (County) to approve a subdivision development proposed by real parties in interest, Y.T. Wong and SMI Construction, Inc. (Developer). The trial court denied the petition. The Tomlinsons appeal from the trial court's order, contending the County abused its discretion in deeming the proposed subdivision exempt from the California Environmental Quality Act (Pub. Resources Code, § 21000 et seq.) (CEQA), under the categorical exemption for in-fill development (Cal. Code Regs., tit. 14, § 15332).*fn1 As we agree that this exemption does not apply, we reverse the trial court's order and remand the matter with instructions to issue a writ of mandate directing the County to set aside its decision.
FACTUAL AND PROCEDURAL BACKGROUND
In December 2006, Developer filed an application with the Alameda County Planning Department (Planning Department) to merge two parcels on Bayview Avenue into one 1.89 acre parcel, subdivide it into 12 lots, and develop each with a single-family home (the proposed subdivision). The proposed subdivision site is located in the Fairview area of unincorporated Alameda County, a residential area primarily consisting of single-family homes. The property is classified for zoning purposes as R-1 residential single-family. Three older structures are situated on the site, but the rear of the property is undeveloped. There are 34 trees on or adjacent to the site. As part of the proposed subdivision, all of the structures would be demolished, and most of the trees would be removed.
In April 2007, Developer revised its application to address concerns raised by various agencies.
On May 14, 2007, the Planning Department issued a referral notifying various agencies and local residents of Developer's revised application and inviting comments. Although the Planning Department had originally contemplated conducting an initial study (Guidelines, § 15063), the referral indicated that the proposed subdivision was exempt from CEQA "based on the site's existing conditions (developed as a low-density residential site with gently sloping land and minimal habitat value), and conformance to the existing zoning for the site . . . ."
On July 2, 2007, the Alameda County Planning Commission (Planning Commission) held a preliminary plan review for the proposed subdivision at its regularly scheduled meeting. The staff report concluded that the proposed subdivision was categorically exempt from CEQA as in-fill development (Guidelines, § 15332) because "the proposed development would occur in an established urban area, would not significantly impact traffic, noise, air or water quality, and could be served by required utilities and public services." The staff report noted that the plans did not meet zoning requirements for guest parking, and one lot violated the setback requirements of a zoning ordinance. Planning Department staff believed a reduction in the number of lots might be required to resolve these issues.
When the Planning Commission opened the floor to public testimony, residents voiced concerns about the loss of views, compatibility with existing homes, additional traffic, parking, and preservation of the mature trees. The chairman continued the matter, noting "this is the direction we've given[,] and we look forward to you [Developer] coming back to us with your formal application."
In an August 2007 email to the County, the Tomlinsons noted that two new developments were underway within half a mile of the proposed subdivision and that there were several other developments within a one-mile radius. They asked for data on recent and planned growth in the area and comprehensive plans addressing the impact on the infrastructure, including traffic, transportation, utilities, and police and fire protection.
On November 19, 2007, the County sent out another referral regarding the proposed subdivision, noting that it had been modified to address comments from various agencies and the public. The referral gave notice that the Planning Commission would consider the proposed subdivision again on December 17, 2007.
On November 30, 2007, the Tomlinsons sent County staff a letter signed by more than 70 local residents, expressing concerns about additional traffic congestion and related safety issues, increased taxes and utility costs, reduced property values, and drainage problems. Noting that other single-family homes less than a quarter mile away had been on the market for a year, the letter expressed concern that the houses in the proposed subdivision could become rentals with multi-family occupancy if they did not sell, significantly increasing parking overflow and traffic in the area. Residents requested an environmental review to evaluate whether the proposed subdivision was consistent with the goals of the general plan.
A few days later, the Tomlinsons pointed out the issues to be considered in reviewing new in-fill projects under the specific plan, including residential density, traffic, parking, public services and utilities, building height, natural features such as mature vegetation and creeks, and retention of existing areas of contiguous open space. The Tomlinsons were "particularly interested in the findings of (what we've read as required in the . . . Specific Plan) an environmental review."
Approval by the Planning Commission
The Planning Commission considered the proposed subdivision at its regularly scheduled meeting on December 17, 2007. Developer had modified the plans to reduce the density of the site to 11 lots. Ten of the lots ranged from 5,000 to 5,186 square feet, and one lot had an area of 7,170 square feet. Each lot would be developed with a two-story, 2900 square foot home.
Planning Department staff indicated that the proposed subdivision "complied with the relevant General Plan, Fairview Area Specific Plan and zoning requirements[,]" "would occur in an established urban area, has no value as wildlife habitat, would not result in significant effects relating to traffic, noise, air quality or water quality, and can be adequately served by all required utilities and public services . . . ." Accordingly, the staff recommended that the Planning Commission find the proposed subdivision "Categorically Exempt ...
