1. Please add an approved seed mix to the plan that will cover all areas disturbed by construction activities and not covered with hardscape. Seed mixes should correspond to the watershed. Consult Riparian Habitat Mitigation Guide for plants in this watershed.

2. Please install a 6" Sch 40 PVC sleeve at a 2.5 foot depth under the road at the Craycroft intersection that extend 2" beyond the driveways on each side within the ROW. Plug ends to prevent backfill dirt from entering pipe.

Comments for the Garden Stone Drive PIA, which I note ties into the improvements that will
be constructed as part of the Blackhawk Ranch Phase 1 PIA:
- Sheet 2: Why is design speed 45 mph (10 mph over posted speed) instead of 40 mph?
- Sheet 3: I recommend that the typical secon is revised to 11 foot travel lanes and 7 foot bu?ered bike
lanes (5+2) (WS4 stripe o?set 2' from WS6 travel way edge stripe). Same comment made on Blackhawk
PIA where this road es in
- Sheet 8: From Sta 14+61 on, the plan shows a broken yellow centerline, which would indicated
motorists can make passing movements on this 35 mph roadway that includes horizontal curves.
Recommend that the YDS4 striping be used the length of the project to prohibit passing movements and
encourage motorist traveling speeds to stay low
Thank you,
Greg
