A "threshold" level of service is needed countywide, but a higher level of service is needed in the urban and suburban areas. At this time, the utility's service area encompasses only those unincorporated urban and suburban areas where the immediate needs are greatest. The County will continue to pay for the threshold level of service from general tax revenues.
This map (PDF) shows the "Service Area" that has been defined as the utility service area. Generally, it encompasses Martinez and Evans within the Reed Creek, Jones Creek, Betty's Branch, and Euchee Creek watersheds. This area has been most severely impacted by recent urban and suburban development.

The County's right-of-way is typically the first 10 feet beyond the curb. This area is reserved by the County for the placement of public utilities such as water lines. Repairs and upgrades are necessary from time to time, and this area has to be excavated.
A modern roundabout is a circular intersection where drivers travel counterclockwise around a center island. There are no traffic signals or stop signs in a modern roundabout. Drivers yield at entry to traffic in the roundabout and then enter the intersection and exit at their desired street.
The waters from the Savannah River and Clarks Hill Reservoir have concentrations of manganese and iron salts. Trace amounts of these minerals pass through the filter systems at our treatment facilities. When the water pressures in the pipes go up or down, the mineral deposits are pulled off the walls of the pipes, causing the water to have a brown or rusty orange color. A mineral deposit the size of a dime can cause water supply to be discolored for an entire house. This does not cause health problems. If your water is discolored you can call the Water Office at 706-863-6928, and the water mains in your area will be flushed.
Any questions concerning paving of dirt roads or resurfacing of existing paved roads need to be directed to the Road Construction Department 706-447-7600.
To improve Stormwater Quality, you can start by preventing pollution. Do things like recycle, throw away trash in proper trash cans, and don’t dump anything down a storm drain. Remember, only rain down the drain!
In Columbia County, only wastewater is collected and transported to the water treatment plant by the sanitary sewer system. Stormwater, on the other hand, flows through the storm system, ditches, and channels. It empties, untreated, into our streams, ponds, and lakes.
Stormwater pollution prevention is stopping pollution from entering the stormwater system and eventually ending up in our local waterways. Water pollution is less visible than flooding, erosion, and sedimentation but still exists.

A speed "bump" is a shorter speed control device that is primarily used in parking lots, they are approximately 12-15 inches wide. A speed "hump" is used as a traffic control device on streets and roads. They are approximately 20 feet or wider.

Columbia County no longer installs "Children at Play" or "Watch for Children" signs. The Manual of Uniform Traffic Control Devices (MUTCD) no longer recognizes "Children at Play" signs. There is no evidence to prove that this sign helps reduce pedestrian accidents or lower speeds and in some instances studies have shown that speeds have increased in areas where these signs are present. Currently, when a "Children at Play" or "Watch for Children" sign is present in a work area, it will be removed.
According to the Manual of Uniform Traffic Control Devices (MUTCD), a stop sign shall not be used to control speed.

This is a common myth, research conducted throughout the country over several decades has shown that drivers are influenced by the type of street and the current traffic conditions and not the posted speed limit.
The placement of speed limit signs are based on several factors. One of the main factors is the functional classification of the roadway. If it is a local road (typical subdivision street), speed limit signs are normally placed only on the local roads that serve as entrances/exits to subdivisions. Usually, none of the interior subdivision streets have speed limit signs placed.
The stop bar is supposed to be placed at the critical point. It should be placed where one will be out of the flow of oncoming traffic and where the stopping vehicle can see oncoming traffic. According to code requirements, the stop sign can be anywhere from six feet to fifty feet from the edge of the intersecting street.
A sewer (top) is usually located in the middle of the road and has no type of drainage from the road whereas a storm drain is usually located at the curb and water is able to drain into it. A storm drain can also be located at the back of property.
