Page: [8] C-301 UTILITIES LAYOUT Author: haileyg File Name: Little Leaf - 1350 Mountain View Drive Civil 11-14-17 Stamped Permit Set.pdf More information is needed on the tap configuration. On the plan drawings show the tap is on the water main line, not on the lateral to the fire hydrant. How will it be tapped to avoid the thrust block? Most likely there is not enough room to tap between the hydrant valve and 90 degree bend and thus the tap will need to be located on the eastern or western side of the main (before the valve). The west side should be investigated as it may eliminate a bend or two in the service line closer to the house, and avoids the sanitary line.
