The Project Scope
Fallon Sports Park is located in Dublin, California, a suburban city of about 60,000 people located 35 miles east of San Francisco, in the region known as the Tri-Valley area which is a triangle-shaped region of the eastern San Francisco Bay Area. Over the last 30 years, Dublin has planned its population growth across former agricultural lands through a series of carefully crafted specific development plans that has organized transportation, housing growth, parks, schools and retail development and used parkland dedication and park development fees paid by new homeowners at the time of home purchase to fund park development. In 2003, the City of Dublin hired Carducci Associates to prepare the master plan for Fallon Sports Park, and identified a 60-acre parcel on Fallon Road in Eastern Dublin as a "park facility to accommodate the majority of competition ball fields in the city." The firm completed phase 2 of the park in the spring of 2018.
The site has an overall elevation change of approximately 100 feet, from north to south. This 100-foot drop occurs over a length of 2,500 feet, creating an overall 4% slope across the site; and much of the site exceeds 5%, which is too steep for sports fields. On the western edge of the park is a continuous 80-foot-wide stream corridor that was developed for environmental mitigation purposes and contains entirely California native riparian plants. The grass-covered, treeless rolling hills provide attractive views to the east, west and to the south. The prevailing western winds often dominate the park environment. The existing soil is classified as predominantly of the Tassajara formation characterized by a high-clay content and poor drainage.
The Fallon Sports includes the following amenities: baseball fields, synthetic turf soccer fields, softball fields, tennis courts, basketball courts, BMX track, children's play area, jogging and walking loop, family and group picnic areas, bocce ball courts, shade structures, restrooms, concessions, public art, lighting for sports fields and parking lots.
In order to create usable, level surfaces for the sports facilities, and to accept soil fill from adjacent developments, two main terraces (upper and lower) have been created. These terraces create a dramatic grade change of 30 feet between each level and significant embankment at the corners of the park. The terracing also allows for two main vehicular entries.
Each field, hub, and parking lot serves as its own watershed and connects to the perimeter storm drainage system. All park storm water is cleaned before it exits the park. No park drainage enters the stream corridor, which is only meant to accept drainage from northerly developments and is intended to be a wildlife corridor as it runs along the sports park. The natural grass sports fields have a "Cambridge-like" sand drainage system in the amended clay top soil.
