Josh,
I phoned earlier and left a message, but this is what it was about. We are having a discussion in the office about
intersection designs and how we should present them for this interim design until the ultimate roadway is built.
Attached are four rough exhibits, two of the WS Phillips /Odell intersection and two of the WS PhillipsNictoria
intersection. Hopefully they are sufficient to convey our thoughts on the designs.
The question is whether we need to build the future left and right turn lanes with our project(s). The problem is
that the left turn lanes are on the wrong side of the road in the interim design. If we build them now, the "inside"
curb will meander in and out, making it confusing for the drivers. I suggest we leave the "inside" curb straight as
shown in Exhibit A. You can envision the alternative by looking at the ultimate design in Exhibit B. This
intersection design will be replicated every 800 feet or so at each residential street. I believe the street will look
cleaner and be less confusing for drivers if it is left straight in the interim. We will still plan to build the left turn
lanes at Greens Prairie, Victoria, and the future street on the adjacent property to the northwest.
On Exhibit D, I have shown a right -turn lane from WS Phillips to Victoria on the Ultimate Design. I also show
the small bike path lane at the intersection as required in the UDO when a right turn lane is provided. It is not
likely that a right -turn lane will be needed at that intersection for a long time, if ever, but I wanted to show there is
room available when/if one is needed. I propose to leave it off of our interim design as shown in Exhibit C.
I'd like to get your feedback on these ideas. I thought it best to ask now rather than wait until a design is
submitted. FYI, we are nearing completion of the construction plans for Section 200. We hope to print them for
internal review early next week. I hope to be ready for our first submittal to you shortly after that. CSC
Engineering is conducting a geotechnical investigation of the site to give us a pavement design. They will also be
conducting an analysis of the Waters of the US. At this time, Rick Conlin feels we will fall under one or more
Nationwide Permits, so it will not be necessary to do much more that simple notification to the COE.
