4. Bid Option 3 – Monument Sign with Accessible Parking: includes but is not limited to new monument sign (wood posts and panel, steel structure, concrete foundations, stone veneer base), asphalt pavement, retaining wall adjacent to parking lot, concrete paving, and a concrete valley cross pan adjacent to the parking area for the monument sign pull-off. Also included in this option is a stormwater solution to route drainage from the roadside ditch beneath the pull-off and back into the roadside ditch to the east.

5. Bid Option 4 – Variable Message Sign: includes but is not limited to wood posts, steel structure, concrete foundations, stone veneer base, trenching/conduit/ power/communications to the sign, a supplemental conduit (laid in same trenching) for future electrical primary replacement, and electronically changeable message sign.
