Appendix B – Visual Resources Documentation
This appendix contains the following supporting documentation on visual resources in the North Coast Corridor (NCC):
- Photo Documentation: Current photographs of various locations along the Interstate 5 (I-5) highway corridor. Table B-1 lists the view locations and the number of photographs that appear for each. Figures B-1A through B-1G are key maps illustrating the locations of each view. The photographs themselves appear on the gallery after the maps, and are lettered sequentially based on their view number (e.g. Figure SD-01A, Figure SD-01B, etc.).
- Proposed Locations of Intermediate Access Points (IAPs), Overhead Signs and Scanners: At the start of the gallery, Figures B-2A through B-2I are maps of proposed locations for Express Lane IAPs, overhead signs and overhead scanners.
- IAP Signage Criteria: The final section of this appendix contains descriptions, schematics and photos of proposed design features for corridor signs at IAP locations.

Proposed Locations of Intermediate Access Points (IAPs), Overhead Signs and Scanners
Intermediate Access Point (IAP) Signage Criteria
1. Placement of HOV/Managed Lanes advance warning signs as outlined Chapter 2G of the 2012 California Manual on Uniform Traffic Control Devices (CA MUTCD).
Minimum advance sign placement is about 1 mile from entry point of the Intermediate Access Points (IAPs) with advance signs to IAP entrance placed in 0.5 mile increments. Tolling signs are placed (at minimum) about 0.25 mile and 0.65 mile from the IAP entrance, respectively. Sign dimensions are summarized in Table 2G-1. Note that the figure below show only regulatory (guide) signs as they apply to IAPs.
2. Minimum Sign and Plaque sizes.
Dimensions of signing outlined on Figure 2G-17 and Figure 2G-24 above are shown on Table 2G-1 with the appropriate signs and highway facility type marked *. See Figure 2G-24 for sign designations. Dimensions are in inches.

3. Overhead signs.
Caltrans Standard Plans S30 show typical placement and minimum clearance from freeway pavement. Signs and sign structures require a minimum vertical clearance of 18 feet from freeway high point and edge of shoulder, respectively. Tubular overhead signs can be specified as slanted or vertical post.
4. Overhead Sign- Single Post Type.
Span (cantilever) range from 20 feet to 38 feet. Height to centerline of mast arm(H) ranges from 21 feet to 29 feet relative to the bottom of base plate and is a function of the sign panel depth(D). Sign panel depth range from 50 inches to 120 inches. H and D in turn would be used to determine the post type and thickness. Please see Standard Plan S31 below for additional details.
6. Overhead Sign- Two Post Type.
Spans range from 50 feet to 145 feet. Height to centerline of mast arm(H) ranges from 21 feet to 29 feet relative to the bottom of base plate and is a function of the sign panel depth(D). Sign panel depth range from 50 inches to 120 inches. H and D in turn would be used to determine the post type and thickness. Please see Standard Plan S32 below for additional details.
8. Plan showing details and dimensions for the same sign structure shown on the photo above.
9. Overhead Sign Truss - Single Post Type
Truss frame length, which is the sum of the left and right arm lengths of the sign structure, range from a minimum 12 feet to a maximum of 60 feet. Standard Plan S4 show details for the placement of sign panels on the sign structure (left and right sides) as well as minimum and maximum length of the panels (0 feet and 40 feet, respectively). Table IV of Standard Plan S4 show truss frame depth and maximum vertical spacing, L, as a function of sign panel depth (ranges from 50 inches to 120 inches).
10. Standard Plan S5
Outline details as to the structural connection and spacing of vertical, horizontal and diagonal elements of the truss as a function of frame length and sign panel depth.
