This program is federally funded and payments are from the budget of the Community Services Department. The rent is $1.00 per year. BACKGROUND This ground lease will provide vacant land to be used to install classrooms and a playground for a Head Start program as requested by the Community Services Department. A Mitigated Negative Declaration for the proposed Fair Oaks Head Start Facility was distributed in March for the required 30-day public review period. A number of comment letters were received from those residing in the surrounding area. The primary concerns raised were related to the shared access with the Pleasant bill Cohousing project and with the increase in trips along Lisa Lane. As a result of those comments, the transportation impacts were further evaluated, and the project was re- planned to eliminate the shared access easement. In addition, the Community Services staff met with the neighbors to further refine the project. A new Mitigated Negative Declaration for the Fair Oaks project was prepared, and was distributed on July 8, 2003. The only comment received was an inquiry from the State Department of Transportation questioning whether a study was prepared to form the assumption that 60% of the students attending the Fair Oaks Head Start program would walk to the site. The Initial Study explains that that transportation data was compiled from existing Head Start facilities in similar demographic areas. Specifically, three other Head Start facilities were reviewed to ascertain the percentage of children who walk to the site, and the percentage that are driven to the site along with siblings who attend the elementary school. In addition, the staff surveyed the Monument Corridor area around the Fair Oaks site to determine the number of families likely to utilize the services, and the percentage of these who would likely walk to the site. The purpose was to identify the new vehicle trips that would be generated by the project. The Community Services staff reports that they are continuing to meet with the members of the Cohousing project and with other neighbors regarding the facility and its operation.

The Elementary School site abuts the Iron Horse Regional Trail and Ken Lester Park (See Site Plan(Exhibit B), Photo Documentation(Exhibit C), and Circulation Plan (Exhibit E). Existing Site Conditions. The approximately 0.80 acre project site is flag-shaped with a relatively narrow portion extending to the west and the larger portion to be used for the classroom building and outdoor play yard extending to the east. Vegetation on the site is reminiscent of the historic oak woodland environment paralleling"Walnut Creek. Introduced grasses form the groundcover. There are several mature walnut trees growing along the northeast fence line and one, large, dead walnut tree occupying the east end of the site.Numerous small Valley Oak trees exist along the site perimeter and through the center of the site. Two tight clusters of Valley Oak saplings(6-12 trees each) exist within the area proposed for the classroom building. 9. Project Description. A new 4,800 square foot,metal-framed,pre-fabricated classroom building is proposed along with an outdoor play yard measuring about 6,080 square feet and parking for up to 25 vehicles. The prototype classroom building contains four separate classroom spaces, rest rooms, a small kitchen and an administrative office space. The proposed locations for vehicular access,parking, classroom building and the outdoor play yard are shown on the Site Plan attached as Exhibit B. A maximum of 20, pre-school age children can be accommodated in each of the four classrooms. There is typically a ratio of one supervisor for each eight children.

(3,6,8) z Discussion of'.Evaluation —Land.Use and Planning; I(a) The project site is located within the boundaries of the City of Pleasant.Hill and the City staff has submitted a letter indicating that a Use permit will be required. However, Government Code Sections 53090-53091 stipulate that cities and counties are exempt from zoning regulations with respect to property that one such entity may own within the territory of the other, The County General Plan commercial land use designation and zoning classification for the project site are consistent with the City designations. Both the City and County allow public facilities subject to a Conditional Use Permit. The proposed layout for the Head Start Classroom project(refer to Exhibit B) shows vehicle access from the south,parking in the center of the development area,the classroom building at southeast edge of the development area and the outdoor play yard at the northeast edge of the development area. The building and paved parking areas would be set back at least five feet from side lot lines and at least 10 feet from the rear lot line. The position of the building and the outdoor play yard east of the parking lot area will minimize the potential for conflict between vehicles and pedestrians. The one-way driveway for ingress to the project site will connect to and share the existing traffic circle located in front of Fair Oaks Elementary School. Motorists travelling to and from the site have the option of using Lisa Lane, from the west, or Hampton load, from the south. Lisa Lane ends at the Fair Oaks Elementary School and is a primary vehicle access for parents dropping off or picking up students at the elementary school. The one-way driveway for egress from the project site will lead back to Lisa Lane at the west edge of the project site. Mitigation Measures—Land Use and Planning. I(a) The proposed site plan is designed to conform to the zoning standards of both the City of Pleasant Hill and Centra Costa County. An easement must be obtained for access through the Fair Oaks Elementary School site to the Head-Start Classroom site. The parking layout shows a maximum of 20 parking spaces. Total parking provided on the site may range from 18 to 24 spaces depending on the final landscaping designs.

Users of the Head Mart classroom facility are expected to encounter seismic shaking at some time in the future. The Hayward Fault, located about 12 miles southwest of the project site, is an active fault likely to experience an earthquake of up to Richter magnitude 7.6 within the lifetime of the project structure. The Calaveras Fault, located about four miles southwest of the project site, is also an active fault likely to experience an earthquake of up to Richter magnitude 7.6 within the lifetime of the project structure. 1II(c) There is a low to moderate potential for liquefaction due to sandy soil conditions and relatively shallow water table resulting from the proximity to Walnut Creek.. Future improvements on the property would be required to conform to the Uniform Building ands Fire Codes. These codes require design to resist seismic events. The project can be designed to incorporate these measures. Mitigation Measures— Geologic Problems: IIIb) Comply with Uniform Building and Fire Codes for building design.

(3,6,8) i) Substantial reduction in the amount of groundwater otherwise available for public water supplies? (3,6,8) Discussion of Evaluation - Water: The project site is currently unpaved. Stormwater soaks into the ground or sheet flows from the center of the site towards the southwest and northeast corners of the site. Pair Oaks Head Start Facility, Initial Study Page 8 Drainage will be altered to the extent that the new classroom building, outdoor play area, parking lot and driveway are impervious surfaces that will reduce the potential for runoff to soak into the ground. The increase in impervious surfaces will cause runoff volume and velocity to increase. Some unpaved landscape and natural areas will be retained around the perimeter of the site. Site grading could result in mud and dirt being tracked onto surrounding streets by construction vehicles and sediment being carried by runoff into the public drainage system. Mitigation Measures- Water. IV(a,1) Provide a closed pipe system to carry rainfall from building roofs and paved areas to the public storm drain system. IV(a,2) Retain as much unpaved area as possible around the building,play yard, parking area and driveway to maximize rainfall percolation. Perform minimal grading outside of the development envelope. Retain natural grades that slope away from the proposed building and paved areas. 1V(c) Require the contractor to clean mud and dirt from surrounding streets and to utilize straw bales, silt fence and straw wattling to prevent sediment from leaving the site during construction. Install irrigated ground cover, shrub and tree landscaping to facilitate runoff percolation and to filter runoff to prevent sediment from leaving the site. Verification-- Water Mitigation: TV(a,1) The building design is reviewed by the County Building Department to verify that proper roof drainage has been provided. The site Grading and Drainage flan is reviewed to verify that a proper connection from paved areas to the public storm drain system is provided. IV(a,2) Grading and Drainage Plans are reviewed by the County:building Department to verify that natural grades outside of the development envelope are retained to facilitate rainfall percolation. IV(c) Grading and Drainage Plans are reviewed by the County:Building Department to verify that Best Management Practices are employed during construction. Landscape flans are reviewed to confirm that suitable, irrigated ground cover, shrub and tree planting is proposed. Fair Oaks dead start Facility,initial study Page 9 Poten.

(3,6,8,10,11,12) ' Discussion r�,f Evaluation —TransportationlCir+cuiation VI(a) It is anticipated that parents will quickly learn that the main entrance for drop-off and pick-up of children attending the Head Start facility is in the vicinity of the existing Fair Oaks Elementary School traffic circle located at the east enol of Lisa Lane. An existing non-exclusive access easement paralleling the east edge of the Iron Horse Regional trail is currently used for access to a multiple family co-housing complex located adjacent to the Head Start site. The project was originally planned to access the Fair oaks Head Start Facility,Initial Study Page 11 site from the non-exclusive access easement. However, the site plan has been modified to access the site (both ingress and egress) from the traffic circle at the Fair Oaks Elementary School. This reduces the potential for traffic conflict with the residents of the multiple family co-housing complex located to the north of the project site. The additions of a sidewalk further improves the safety of children walking to and from the site. Most of the parents driving to the Head Start Classroom site are expected to arrive for morning drop off between 8:00 AM and 8:30 AM, a time that is later than the 7:20 AM to 7:50 AM drop off time for elementary school children. This will minimize conflict between Head Start traffic and Elementary School traffic. The proposed parking lot layout for the dead Start site provides more than ISO linear feet of curb drop off space for students(enough length to accommodate at least six vehicles at a time). The traffic pattern within the site is a one-way traffic pattern with aisles wide enough for cars to pass, and parking for between 18 and 24 vehicles including one handicap parking space. The proposed one-way, circular driveway design allows easy ingress and egress for vehicles if multiple vehicles arrive at or about the same time. The four new Head Start classrooms are expected to accommodate up to 80 students and will be staffed by up to 10 supervisors. It is anticipated that all of the supervisors may drive to the site daily(maximum 20 vehicle trip ends per day). Data compiled at existing Head Start facilities in similar demographic areas of the County indicates that up to 60 percent of the students walk (48 students) and another five to ten percent(four to eight students) arrive in the same vehicle as elementary school siblings. Using this data it is estimated that 24 to 28 students would be driven to the site each day. Combining both staff and student-related traffic results in an estimated total of 116 to 132 trip enols per day. Hours of operation are from 6:30 AM to 6:30 PM thus the facility has the potential to add a minor amount of traffic during the peak hours of the adjacent Fair Oaks Elementary School. The planned service area for the Head Start classroom building is the Monument Boulevard corridor generally coinciding with the Fair Oaks and Cambridge Elementary School attendance areas. These attendance areas are both located east of Highway 680 thus travel to and from the school is not expected to affect highway 680 traffic. VI(c) The proposed parking lot area on both Site Plan alternatives provides convenient access for emergency vehicles to turn around on site. Safe and convenient access is achieved by a one-way circular drive meeting Fire Department turning radii. VI(e) The proposed site plan includes a pedestrian: sidewalk leading from Lisa Lane to the Head Start classroom building. A secondary walkway is proposed between the Mead Start classroom building and the Fair Oaks Elementary School main entrance plaza. Existing sidewalks and pedestrian crosswalks provide safe areas for students and parents to walk.along Lisa Lane. The existing Iron Horse Regional Trail provides safe pedestrian access in a north south direction from Monument Boulevard on the north, past Lisa Lane and through Ken Lester Park to the south. Fair Oaks Head Start Facility,Initial Study _ �� Page 12 Mitigation.Measures— TransportationlCirculation; VI(a,1) The project site plan has been modified to include ingress and egress from the traffic circle at the Fair Oaks Elementary School. This allows vehicles to move easily into and out of the.Head Start site while minimizing conflicts with residents commuting from the co--housing complex and parents dropping off or picking up students at the Fair Maks Elementary School. The Site Plan has been designed with at least 150 feet of on- site curb space to drop off and pick up students so that sufficient space is provided when multiple vehicles arrive at the same time. VI(a,2) Consideration should be given to establishing a drop off and pick up schedule for the Head Start facility that will avoid dropping off Head Start students between 7:20 and 7:50 A.M. so as to minimize conflicts with established drop off times at the Fair Oaks Elementary School and residents leaving the co-housing complex on their way to work. This scheduling would not apply to Head Start students being dropped off at the same time as siblings being dropped off at the Fair Oaks Elementary School. VI(a,3) The parking lot layout allows the spaces in the center of the parking lot to be assigned to all day vehicle parking for up to 10 supervisors. Spaces at the curb should be reserved for short term parking related to droop off and pick up of students so that students are not required to cross the path of oncoming vehicles. VI(c) The one-way parking lot layout facilitates safe and convenient access for emergency vehicles allowing vehicles to enter and exit the site without the need to back up. VI(e) Pedestrian sidewalks and crosswalks are proposed to serve the Head Start classroom site. A long sidewalk in front of the classroom building will provide a safe location for student loading and unloading. A new pedestrian path will connect to the existing Fair Maks Elementary School main entry plaza. Existing sidewalks, regional pathways and crosswalks provide pedestrian linkages to surrounding residential areas.
