Site Layout, Access, and Circulation
<br /> The proposed subdivision is located just south of Dublin Creek. The location of the adjacent
<br /> creek and creek setback has been used to determine a suitable area for the development, with
<br /> all buildings, structures, and paved areas placed outside of the 20-foot creek setback
<br /> established in the prior approval. The Traffic Engineering Division, Engineering Department,
<br /> and Fire Department have reviewed the proposed site access including turning radius within
<br /> the site and have found it acceptable. The main entry is centrally located and at a similar
<br /> location as the originally approved entry that allows for ingress/egress to the project from
<br /> Dublin Canyon Road, which has a speed limit of 45 miles per hour. The secondary driveway
<br /> access is located on the far west side of the site buffered by a 15-foot landscape strip directly
<br /> adjacent to an existing single-family home. This driveway is to allow better access and
<br /> circulation for deliveries and garbage, as well as to accommodate emergency vehicles.
<br /> In addition to the on-site improvements, the applicant would be required to provide various off-
<br /> site improvements as described previously including a new bicycle lane along Dublin Canyon
<br /> Road, meandering path on the north side of Dublin Canyon Road, and turn pockets and
<br /> deceleration lanes into the project. Staff has included conditions addressing these items.
<br /> Additionally, the applicant will be required to pay the required regional and local traffic fees.
<br /> Arborist Report and Landscape Plan
<br /> An arborist report was submitted assessing the existing trees on the subject site. The
<br /> proposed landscape plan has a list of plant species including a mix of native and non-native
<br /> plant species with low water use requirements. At the conclusion of the Planning Commission
<br /> work session, the applicant reviewed their proposed landscape plan and based on the required
<br /> undergrounding of utilities along Dublin Canyon Road, the meandering sidewalk, and the
<br /> overgrown state of the existing trees, the applicant is proposing to remove the majority of the
<br /> trees along Dublin Canyon Road and replant a new palette of native species trees and shrubs.
<br /> Since final construction plans have not been finalized, the City's landscape architect is
<br /> requesting that the applicant continue to explore options to save trees if feasible, particularly
<br /> trees 946, 951, 952, and 953 along Dublin Canyon Road, but understands the difficulty caused
<br /> by the required utility infrastructure improvements. In addition, the applicant is proposing a 15-
<br /> foot landscape strip along the west property line adjacent to the nearest single-family
<br /> residence to be planted with 'Saratoga' Sweetbay. After reviewing the final plans, the City's
<br /> landscape architect has included conditions of approval that require the Dublin Canyon Road
<br /> frontage trees to be modified to be primarily native oak trees as well as native shrubs to retain
<br /> the rural feel of the area. Additional trees will also be planted along the interior perimeter of the
<br /> site as well as within the parking lot area.
<br /> Based on concerns discussed at the work session regarding screening of the parking lot, staff
<br /> including the City's landscape Architect worked with the applicant to review the plans and
<br /> believe the proposed landscape palette along Dublin Canyon Road directly in front of the
<br /> proposed parking is appropriate to screen the parking. The proposed plants to be utilized for
<br /> screening are summarized in Table 2, and, in addition to the trees to be planted, include
<br /> shrubs and perennials with dense foliage and a mature height of three to six feet, intended to
<br /> provide screening of vehicles parked within the parking lot, which sits between 1 to 2 feet
<br /> above the finished grade of Dublin Canyon Road decreasing from east to west. Overall, staff
