The USFS contracted with AEC to design this project to provide suitable access along 4 miles of historic but dilapidated railroad grade, to accommodate a Type III Forest Service fire engine. This would result in access for forest fuels reduction and emergency access for the Glenbrook area. The road design required a number of specific details for crossing wet or environmentally sensitive areas, and geocells were utilized to stabilize these areas. The roadbed was approximately 12-feet in width in natural terrain with over 30% existing cross slopes. This resulted in significant retaining wall designs in certain locations to support the roadbed. An alternative analysis was completed for the required retaining walls, design alternatives required approval from the Nevada State Historic Preservation Office (SHPO). The AEC team prepared the roadway log, retaining wall design report, and plans and specifications for the project.

Project Description: The United States Forest Service (USFS) contracted with AEC to provide design services for this reconstruction and retrofit project. The Project included redesigning the day use area to maximize efficiency of the paved surfaces for parking, to increase the number of parking stalls to 160, and to provide BMP’s for the site located in sandy soils very close to shoreline of Lake Tahoe. The site consists of three individual, interconnected parking lots, each of which was graded to allow the stormwater runoff to sheet flow to large central landscape island.
