City of San Leandro 2824 Halcyon Drive Residential Project 8 Parcel A would be situated on top of an underground storage box for hydromodification.1 The project’s drainage systems would be designed to comply with the Alameda Countywide Clean Water Program, C.3 Stormwater Technical Guidance and Alameda County National Pollutant Discharge Elimination System (NPDES) Municipal Stormwater Permit. Fencing New 6-foot precast concrete walls 2, painted to match the existing precast wall, would be constructed along the southern perimeter of the site to fill in gaps in the existing precast wall. Within the project site, 6-foot-high wood fences would be built around each of the residences to separate each lot. Landscaping The project would include a total landscaped area of 19,600 square feet, or approximately 19 percent of the site. Landscaping would include front yards, planter strips, and the shared passive use open space area located at the southeastern corner of the project site. This shared open space area would also act as a drainage management area and contain underground storage boxes which would be part of the larger drainage management and bioretention system occurring on the project site. The landscaped and bioretention areas located throughout the project site are indicated as the shaded and dotted portions of Figure 3. Approximately 0.78 acre of the site is comprised of mixed ornamental woodland trees that would be removed as part of the project (ficus, redwood, Mexican fam palm, Himalayan cedar, acacia, lemon, southern magnolia, pine, tree of heaven, loquat, and willow) (Appendix BIO). There are 18 new street trees (London plane trees) proposed along the new public street as well as a variety of accent trees along the perimeters of the southwestern and northeastern courts connecting to the new public street that would connect Muscari Street and Elderberry Way, and in the front yards of proposed residences. The proposed plant species list can be found in Appendix PLAN. A fully automatic irrigation system would be installed throughout the bioretention areas to provide supplemental irrigation in the dry months which would utilize water conserving methods (Appendix PLAN). The project would include 23 individual bioretention areas landscaped with shrubs and grasses. There would be one bioretention area in front of each residence as well as at the end of the northeastern court and intermittently along the new public street between the pavement and the sidewalk. Lighting The project would include new outdoor lighting fixtures including streetlights along the new public road and one coach light on the front of each residence. Site Preparation and Construction The existing two residences and two accessory structures would be demolished and hauled away by the contractor to Argent Materials in Oakland, California, approximately 6.3 miles from the project site. Demolition would comply with the City’s Construction & Demolition Debris Waste Reduction 1 Hydromodification refers to “the alteration of the natural flow of water through a landscape” (Law Insider). 2 Precast concrete walls refers to walls created by pouring concrete into a reusable wall mold or form and curing the molded concrete in a controlled environment at an off-site location. The cured, molded concrete is then transported to the construction site and lifted into place (The Constructor 2020).
