The project team analyzed four alternatives (including a no-build option) for the intersection at Fort Johnson Road and Secessionville Road
To determine which alternative best met the project goals, the project team evaluated right of way (ROW) impacts, grand tree impacts, property relocations, construction costs, and the projected traffic impacts. Staff recommends Alternative 1, a Traffic Signal, for the intersection at Fort Johnson Road and Secessionville Road. Below you will find the recommended alternative and the additional alternatives the County considered.
|Grand Oak Tree(s) Removal||1|
|Level of Service* AM/PM (up to year 2037)||B/B|
|Construction Cost ($ Million)||$1.8|
|Grand Oak Tree(s) Removal||0|
|Level of Service* AM/PM (up to year 2037)||B/C|
|Construction Cost ($ Million)||$1.5|
|Grand Oak Tree(s) Removal||3|
|Level of Service* AM/PM (up to year 2037)||F/F|
|Construction Cost ($ Million)||$1.6|
*Level of service (LOS) is a scale that rates how well a transportation facility is operating from a traveler's perspective. Typically, the six levels of service are rated from A to F, with LOS A representing the best operating conditions, and LOS F the worst. Project managers use LOS to describe how a roadway or intersection is currently functioning, or how they will function in the future with or without improvements.
If you are considering all modes of transportation, why are there
not sidewalks through the entire construction limits?
We will keep existing sidewalks in place and add proposed sidewalks where there is not property owner opposition.
I don’t understand why we can’t simply put up stop signs and make an all way stop?
In order to utilize an All Way Stop Control (AWSC) for this intersection, it must meet SCDOT criteria. The level of service with AWSC, even with turn lanes, is not acceptable and would create excesive delays. This delay exceeds what SCDOT standards allow.
What type of trees are being impacted?
The intersection improvements project will result in impacts to a 38” water oak in poor health.
