documentation for reimbursement of the trails construction costs using its TDA fund allocations for years 2004-05 and 2005-06. Honorable Mayor and Members of the City Council: BACKGROUND A pedestrian/equestrian trail was proposed as part of the planned open space surrounding the Callippe Preserve Golf Course. The trail is approximately two miles in length and varies in width from 40 to 60~inches. City Staff approached the United States Forest Service about providing training in the design, construction and maintenance of trails. The City and the U.S.F.S. entered into a service agreement that authorized the training of staff and the construction of the Callippe Golf Course Preserve trail. The U.S.F.S. group providing this service is referred to as "Trails Unlimited". Trails Unlhnited has completed the training and the construction of the trail. The service agreement with U.S.F.S., Trails Unlimited, was for an amount of $68,625 and included a contingency of ten percent for a total agreed amount of $75,000. Trails Unlimited laid out a trail alignment with an objective to limit long-term maintenance as well as immediate construction costs. During the approval process, the California Regional Water Quality Control Board and the City's Golf Course Architect conducted a field review during the construction phase and requested changes that altered the trail alignment and the addition of storm water culverts where the trail crosses seasonal watercourses. The trail's alignment was moved further away from the Golf Course's fairways and greens at holes 12 and 18 as a safety precaution against errant golf balls potentially striking users of the trail. These changes pushed the trail to higher elevations, which in turn, created greater differences in elevations between the high and low spots where the trail crosses the seasonal watercourses. To limit the maximum trail grade to 20% for short segments of the trail, the length of the trail had to be increased by extending the trail back into the adjacent canyons. These canyons have steep side slopes and required lateral bracing (retaining walls) at switchbacks to brace against potential erosion and slope failures onto the trail. The California Regional Water Control Board also requested an increase in the number of arch culverts under the trail at water crossings to better disperse flow in local ephemeral creeks as they pass under the trail. Amendment No. 1 was authorized by the City Manager in the not-to-exceed amount of $26,410 to cover the changes to the scope of work. Actual costs for the changes were $22,535.00. SR:05:006 Page 2 of 3
