Summary aud Conclusions The proposed new development is estimated to consist of residential units, o.ffice space, retail, and a Town Center exp~sion. Based on the traffic analysis provided, our recommendations and conclusions re'e: 1. The number of residential units was changed in mid-May.2005. Theapartments have bebn eliminated and the total ntm~ber of residential uni'ts was. changed to 686. This change has minimal impacts on the trip generation and no impacts on. the final lane and traffic control needs. 2. An opening year of 2007 is set for all the development projects in this area. With the full development of the Pulte. Site, Town Center I, and the Superstore,. improvements will be required ~t intersections surrounding the site. These improvements include the addition of traffic lanes, a chan~ in traffic control, or ' 'major intersection reconstruction. -' -- 3. By 2007~ signalization should be considered at the intersection oFAtpine Drive and TH 10 based:on level of service analysis. Additionally, a six-lane Tt-[ 10 would bring LOS to D or better for ail movements, By 201.7, delay considerations l:or the intersection would requii'e a fidl interchange at TH 10. Although the delay is high, with the low volume of traffic on Alpine Drive it is unlikely that this intersection would meet any signal warrant analysis. If additional development occurs to the west on Alpine Drive~ the volume of traffic ush~g the .intersection may warrant signalization. 4. The intersection of'Alpine Drive and Armstrong Blvd. wilt requireimprovements before and after 2007.' These include the addition of multiple lanes and signalization as illustrated in Figures 9 and 10. By 2030, the volumes traveling ' north and south are likely to require a four-lane divided Am~strong. 5. The intersection or'Armstrong and InduStry Avenue requires extensive reconstruction to bring all movements to LOS D or better by 200Z These improvements include the reconstruction of each roadway to a four-lane roadway . with fulI turn lanes'~ Additionally; due to the hi.~'~ tm'ning volumes, dual leR turn lanes are required both northbound and westbound. - 6. After 2007, the roadway network should be redesigned to better accornn't0date the traffic, from the sites and take off the .pressure. fi-om Armstrong and Industry. The proposed re-alignment of Armstrong Boulevard would greatly improve operations' and traffic flow through the area. 7. With the new alignment 6f ga'mstrong, a new Armstrong and Industry intersection will be built. By 2017, this intersection wilt require a four-lane roadway on each approach with full turn lanes. Dual left turn lanes will also be r-equired westbound, northbound, and-southbound. By 2030, the volumes wil! be mlsed such that a tr/ple left westbound is required. This design will require a six-lane Armstrong south of Industry Avenue. Other options to alleviate this potential problem include an interchange design that allows for westbound left turns to move fi'eely or by keeping a half-diamond intemhange to the east on TH 10 off the existing Armstrong Boulevard.
