6 Skew Angle - WINDSOR Pkwy intersects ROSWELL Rd at a 57 angle (90 is ideal) Split-Phase - As a result of the skew angle, the signal cannot allow the east and west movements to occur at the same time for safety reasons and green time is reduced Turn Lanes - WINDSOR PARKWAY is a 2 lane approach with a left thru and a right turn lane Separation and Queuing are not Desirable: Signal separation between the ROSWELL road with WINDSOR Pkwy and W. Wieuca Rd is 700 (GDOT criteria currently requires 1,000 minimum) Substandard separation creates vehicle stacking and weaving movements that degrade operations The vehicle queue northbound on ROSWELL road often blocks the INTERSECTION with Meadowbrook road and spills back through West Wieuca and often Wieuca Roads Traffic Volumes: Existing volume of left turns from westbound WINDSOR Pkwy to southbound ROSWELL road are at the threshold volume to warrant a dual left turn lane Traffic volumes on ROSWELL road are heavy and demand the majority of signal green time creating longer delays on WINDSOR Pkwy 11 WINDSOR PARKWAY INTERSECTION Overview Operational Summary Future Condition Level of Service (LOS) C Projected: Skew Angle: Corrected to a 90 Split-Phase.

7 Signal can run without split phase allowing improved operation (frees up an estimated 25 seconds of green time per cycle) Turn Lanes: WINDSOR Pkwy configured with 2 left turn lanes in all current options under consideration Separation and Queuing are more Desirable: Future options result in additional stacking and queuing length on ROSWELL Rd. of approximately 300 between West Wieuca and new WINDSOR PARKWAY re-alignment. This meets City and GDOT criteria requiring 1,000 minimum spacing between traffic signals Traffic Volumes: The new design does not reduce traffic volumes; however, it provides additional turn lanes and improved signal operation to improve the level of service at the INTERSECTION 12 Related Actions West Wieuca Turn Lane (City of Atlanta) Level of Service (LOS) A for the Existing and Future Conditions 13 DRIVE #3 NORTH WINDSOR PARKWAY INTERSECTION Relocation Option #1A (Auction site) 14 WINDSOR PARKWAY INTERSECTION Relocation Option #1A Pros: Greatest level of service provides for dual left turns, dedicated through and right turn lanes Provides a 50 buffer from WINDSOR PARKWAY to the townhomes Increases queuing length Cons.

9 Highest total construction cost Displaces active restaurant Least amount of queuing length along ROSWELL road Reduced level of service of overall INTERSECTION due to lack of dedicated right turn lane onto ROSWELL road 19 WINDSOR PARKWAY INTERSECTION Relocation Cost Estimating Methodology Construction Cost Estimates Prepared by Michael Baker Corp. using GDOT Mean Item Summary construction cost database. 10% contingency applied due to concept stage of design Property Valuations Prepared by Carr, Lawson, Cantrell and Associates Real estate using Sales Comparison Approach for parcels under consideration Business Impact Market range formula provided by HDH Advisors to assess business enterprise value 20 WINDSOR PARKWAY INTERSECTION Relocation Options Planning Level Cost Comparison Option #1A (Auction site) - $ Option #1B (Auction site) - $ Option #2 (Restaurant site) - $ 21 WINDSOR PARKWAY INTERSECTION Relocation Funding Options Impact Fees (CIE)
