SUBJECT: Request for Design Documentation of Proposed Marked Crosswalk
Approval for aproposedmarked crosswalk is requested for this project.
PROJECT DESCRIPTION
Provide a general description of the project including city and street location, length of project, proposed improvements, speed limit, design speed, and amount of TE funds awarded to the project. Indicate which roadways included in this design documentation are on the State Highway System and which are local roads.
FEATURE(S) REQUIRING DESIGN DOCUMENTATION
Provide a general description of the benefits of the proposed marked crosswalk. (Examples: The proposed marked crosswalks located at station xx+xx on xx Street. The marked crosswalkwould improve pedestrian safety, accessibility,and facilitate connectivity to existing/proposed parking areas along the project corridor. The crossing would also be a traffic calming device. Two accessible ramps and striping at an existing uncontrolled mid-block crossing would be replaced with the proposed ADA accessible marked crosswalk. The proposed marked crosswalk would be surfaced with stamped asphalt or concrete in contrasting colors to visually delineate the crosswalk. In addition to this architectural treatment, an 8" white thermoplastic stripe would be placed parallel to the crosswalk on each side.)
GDOT STANDARD CRITERIA AND ANALYSIS
Section 12.4 of GDOT's Signing and Marking Design Guidelines version 4.0 Table 12-1 provides guidance on marking crosswalks. Provide explanation why marking the crosswalks meets the GDOT criteria. List current traffic data relative to GDOT’s signing and marking crosswalk guidance.(Examples: Vehicle ADT on XX Street is less than #,000. The speed limit is ## mph. The street is a local two-lane thoroughfare. Sight distance is xxxxxx linear feet to the north and xxxxxxx linear feet to the south. The proposed crosswalk would be approximately xxxx feet from a controlled intersection. Provide actual or estimated ADT for roadway to demonstrate that the ADT is less than the ADT figure in Table 12.1. Add the percentage of truck traffic for the corridor. Add the estimated number of pedestrians that would utilize the crossing on a daily basis.) Add finding that perSection 12.4 of GDOT Signing and Marking Design Guidelines version 4.0 Table 12-1, this location is a candidate for a marked crosswalk.
RECOMMENDATION
Based on this guidance, adequate sight distance, and low vehicular volume, I, Name, Engineer of Record, document the decision to construct a marked mid-block crossing for these locations and conclude this proposed mid-block crossing would not present an increased safety risks to pedestrians.
Should you have any questions please feel free to contact me at Name, email address or telephone number.

** The following section must be on an individual page within the letter. Include a separate signature section for each marked crosswalk location, for example,one signature section for proposed marked crosswalk at station 10+50 on Main Street/SR14, an addition signature section for proposed marked crosswalk at station 12+50,Main Street/SR14.
The above analysis documents the decision, to mark a crosswalk(s) at station ###, ### Street following GDOT guidance on marking crosswalks.
