I am new at template creation and coming from Power Geopak SS2 to OpenRoads Designer. I am working on our company standards to meet local municipal street section requirements. What is the best means of creating a 50' R/W 28' BC/BC 2 lane template with roll curb and sidewalk on the left side only backed up to the R/W? Typical section is 2" S9.5B finish course, 3" Type I 19/0 X Base Course, 8" CABC Stone. Should I start with one of the built-in templates and modify or start from scratch?
