MEMORANDUM 
 
 
TO: Ben Burchfield, Public Works Director 
 
FROM:  April Johnston, Street Superintendent  
 
DATE:  August 22, 2023 
 
SUBJECT:        North Jackson Street Repairs  
 
It was brought to Public Work’s attention that North Jackson Street directly in front of 
City Hall was beginning to experience asphalt  failures.  I inspected the area and 
determined that longitudinal cracking was beginning to reveal a subgrade issue from the 
roadway surface extending behind the concrete curb.  The edge of roadway has settled 
significantly, and safety barrels were placed to keep vehicles off the area  until further 
investigation could occur.   
 
I contacted Gresham Smith Engineering firm to vi sit the site and requested they provide 
a proposal for engineering services  to investigate the cause of the failure .  The section 
abuts Norfolk Southern railroad right of way and is approximately 250 linear feet by 12 
feet wide.  The subgrade  failures have p rogressed to  the point that they need 
immediate reconstructive effor ts.  Gresham Smith has provided a proposal to collect 
field survey data , design stabilization of the roadway section, and include g eotechnical 
services for the roadway.  This will provide the data needed to fully assess subsurface  
soil conditions and identify the cause of the s ubsidence issues. Based on the se findings, 
they will provide construction bid documents for the remediation project.   
 
This choice to bid the work is due to the amount of excavation and compaction that will 
be needed for this project, which extends beyond Public Works ability to complete with 
regards to type and amount of equipment and manpower.  Construction will need to 
commence and finish quickly so as  not to cause more damage to the sub -surface of the 
roadway which could result in a slip or fallout which could adversely impact adjacent rail 
operations.
