turnaround on site. How will truck tires be kept clean of debris while on site? Maybe a rock
construction loop could be provided on site?

truncated domes.
th
9.An ADA compliant curb ramp is required at the corner of 234 & Highway 99. In looking
through City standard details, detail E2.16 looks to be the most appropriate, less a curb ramp for
crossing Highway 99. Truncated domes are required at this intersection. Please reference and
provide detail (with modifications) within plan set.
th
10.Please provide curb/gutter elevations at the NW corner of 234 & Highway 99. Will an
additional CB be required in this area?

th
Placement of curb on north side of 234 should allow for a minimum of two (2) 12 lanes.
12.Curb and gutter shall not be placed over the top of water valves and shall be shifted to the north
as required to avoid this conflict.
13.It appears as though the power pole at the west end of the new sidewalk will need to be
relocated. The new concrete sidewalk will need to be constructed to the west property line with
a 1:12 max slope ACP ramp at the west end of the sidewalk.
14.The fog line shall be repainted as required to match existing.
15.A retaining wall has been shown along the east edge of the parking lot and is shown to support a
