AUGUSTIN BERNAL MOUNTAIN BIKE TRAIL PROJECT DRAFT INITIAL STUDY The proposed trail would require an access easement with the Golden Eagle Homeowner's Association (HOA) because the HOA owns land between the staging area parking lot and Augustin Bernal Community Park that the proposed alignment would cross.The easement is anticipated to extend approximately 50 feet on either side of the trail alignment to allow for construction and maintenance. In addition to developing the proposed trail, the City also proposes to decommission approximately 4,300 linear feet of existing user-created trails,as shown in Figure 6.Trails to be Decommissioned.This would involve removing constructed features such as berms and jumps, rehabilitating soil, and broadcasting a seed mix to promote new vegetation growth. Project Site Characteristics The project site is located within Augustin Bernal Community Park, which is a destination for cyclists and hikers from the City of Pleasanton due to its nine major trails, as shown in Figure 4. Augustin Bernal Community Park is known to support a mosaic of vegetation communities and species, and scenic views and vistas (see Figure 7, Scenic Views), along with its biking and hiking trails. The three other biking trails within the park have slopes that range from an average of 5%to 9%downgrade(City of Pleasanton 2019a). Currently,the project site hosts several unofficial trails and trail spurs.The use of unofficial trails that have not been designed has resulted in sections with higher risk of erosion and rutting, as well as improper banking and other deficiencies. Figures 8a and 8b, Existing Trail Condition Photos, provides examples of these degraded or deficient sections. The parking lot on Golden Eagle Way was originally constructed in 1993 and was expanded in July 2018 in response to public input.Currently,the staging area contains 4 horse trailer spaces,41 vehicle spaces,2 ADA parkingspaces, and a restroom. Golden Eagle Way is accessed via residential roads off of Foothill Boulevard and is accessible only to City residents and to non-residents who first obtain a no-fee permit card from the City. Existing Land Use and Zoning • General Plan Land Use Designation:Augustin Bernal Community Park is designated Parks and Recreation and the portion of land owned by Golden Eagle HOA that the trail would cross is designated Agriculture and Grazing(City of Pleasanton 2009a). • Zoning:The Augustin Bernal Community Park and parking lot/staging area are zoned Public and the portion of land owned by Golden Eagle HOA that the trail would cross is zoned Planned Unit Development - Low Density Residential(City of Pleasanton 2018). Surrounding Land Uses The project site is surrounded by existing park and recreational facilities. Most of the trail would be contained within Augustin Bernal Community Park, but the lower third of the trail would cross Golden Eagle HOA property,subject to an access easement.To the west, north,and south is Pleasanton Ridge Regional Park,which consists of more than 9,000 acres and is owned and operated by the East Bay Regional Park District.To the south is Castlewood Country Club, a private golf course. Augustin Bernal Community Park lies on the western boundary of the City. The City boundaries extend approximately 4.75 miles to the north and approximately 5.75 miles to the east. 12956 DUDEK 9 April 2022
