The attached sketch shows the new layout for the storm drain at Belt Line connection as per our conversation in
the field yesterday morning. I followed the City's recommendation moving the proposed 72" storm pipe to the
south to avoid any conflict with the traffic, and to make the construction work on the grass area. I also made a 22
1/2 degree connection to the existing culvert as the City's Inspector required. I believe that this alternative
minimizes the construction on the asphalt pavement area, as it was requested by the City. Please provide to Pac
Trust any impact of the construction cost with this alternative and also request approval from Mat Oyen prior to
any field work. Please call me for any clarification.
Thanks
