BACKGROUND The Pedestrian and Bicycle Master Plan recommends a paved trail on the south side of the Arroyo Mocho canal from Hopyard Road to the eastern City limit. The project includes three different paving methods to "test" the performance properties of the three materials. The plans had been reviewed and approved by the Bicycle, Pedestrian, and Trails Committee, and the Parks and Recreation Commission. This project consists of paving the Arroyo Mocho trail on the south side from Sutter Gate Avenue to Guzman Parkway with asphalt paving and two innovative test sections. The existing asphalt-paved trails along the Arroyo Mocho and the Arroyo De La Laguna have experienced major distresses and have become a significant maintenance concern. The Engineering Division investigated the issue and determined that the distresses are a function of the underlying soils and the trails' proximity to the sloping channel bank. In efforts to reduce the maintenance impacts and create a smoother riding surface, the Engineering and Traffic Engineering divisions worked to identify some alternative paving materials. It was determined that using a decomposed granite (DG) surface, porous concrete, and strengthened asphalt are viable long term trail surface alternatives. The three alternate trail surfaces (in one segment each) are proposed to be installed as part of the project to determine the acceptability, durability and maintenance of the three options. The first segment of trail will be a test section of decomposed granite (DG) with a resin binder (TerraPave). The segment will be 12' wide and located between Sutter Gate Avenue and the Stoneridge Drive Bridge (approximately 1700 LF or 0.3 mile). The second segment of the trail under the Santa Rita Road & Stoneridge Drive bridges will be 10-feet wide pervious concrete. This section will not include a two-feet wide DG running path alongside the concrete trail because the trail surface is below the wet weather, high water line and would likely wash away during the rainy season. Zone 7 Water Agency requested the addition of four-feet-wide geoweb for slope protection in the channel along this section which is included in the project plans. The third segment, from Santa Rita Road to Guzman Parkway (upper trail), will be a ten- feet wide asphalt trail with two-feet wide DG on both sides, and three-feet-wide native vegetation at the edges. The asphalt paving will be strengthened by adding geotextile fabric below the surface. The three-feet-wide vegetation requirement is a condition from California Department of Fish &Wildlife (CDFW). Due to the date restriction from CDFW, the anticipated start of construction is July 15th and the anticipated project completion date is October 15th. A schedule is provided with this report to accommodate this time restriction. During construction the access to the trail will be limited. There will be construction traffic from Hopyard Road to the east end of the trail. The first and second segments will be closed for pedestrian traffic but there will be access at Sutter Gate Park. At the third segment, east side of Santa Rita Road, pedestrians will be directed to the lower trail through the gate at Santa Rita Road and a fenced walkway provided by the contractor. Page 2 of 4
