This project involves accessibility improvements to the existing Doane Pond & Thunder Springs Trails at Palomar Mountain State Park. Accessibility improvements are designed to bring the trails in compliance with California State Parks accessibility guidelines and associated legal mandates. Project implementation will meet accessibility requirements and guidelines as stated in “California State Parks Accessibility Guidelines” and the federal access board’s outdoor recreation guidelines, and will assist in meeting the legal accessibility requirements as stated in the (Tucker v. California Department of Parks and Recreation) consent decree. As a designated Level 3 park for accessibility, it is the Department of Parks and Recreations (DPR) responsibility to address providing at least 0.5 miles of accessible trails within the park unit. Once implemented this project would create approximately 0.73 additional miles of accessible trails. The existing Doane Pond Trail is an approximately 0.3 mile trail that originates at the Doane Pond Day-Use parking lot and loops around the pond. The accessibility improvements will reconstruct the existing trail and one adjacent picnic/shade ramada area. Small section of the existing trail along the southeast side of the pond will be shifted a couple of feet away from the pond edge. On the northeast side of the pond a vehicle fish unloading area & overlook area will be constructed to provide a location for Department of Fish & Wildlife to restock the pond. The existing Thunder Springs trail is an approximately 0.43 mile trail that originates on the Doane Pond Trail and ends at the juncture of the Chimney Flats and Upper Doane Valley Trails. Only the portion of the trail from Doane Pond Trail to near the Thunder Springs will be improved to accessibility guidelines. Of the existing trail that is going to be improved, 80% of the trail will be relocated up the slope away from the Doane Creek edge. Relocation of the trail will include the removal and restoration of the existing Thunder Springs trail. The type of improvements on one or both trails will include accessible parking, signage, wall-less turnpikes, wood turnpikes, drain lenses, rock causeways, retaining walls, boardwalks, armored drain crossings, puncheon, and 4 bridges. Three accessible parking spaces will be reconstructed at the Doane Pond Day-Use parking lot.
