Fire hydrant locations are determined by the Cherokee County Development Regulation Section 4.17.C and the Water and Sewer Authority. The state-adopted 2012 International Fire Code minimum standards are met by the Cherokee County Development Regulations and Water and Sewer Authority Specifications. Keep in mind that an existing hydrant might meet the below requirement if located on the same side of the road. Required Fire Hydrant locations are as follows:
- Within 300-feet of the building structure (This distance is measured along paved surfaces. We do not measure across fields, landscaped areas, medians, etc.
- Hose lay distance can be extended to 500-feet for structures that meet Sprinkler System requirements.
- Show existing hydrants if available.
- Hydrant Installation Standard Detail (This should be obtained from the Cherokee County Water and Sewer Authority)
- Fire hydrants shall be installed so the centerline of the hydrant steamer connections is a minimum of 18-inches above grade or the barrel flange is 6-inches above the finished grade.
- The steamer connection shall face the mid-line of the street for accessibility.
- Hydrants should have 3-feet of surrounding unobstructed area based on the 2012 International Fire Code.
- Fire Hydrants must be operational and under pressure prior to the start of combustible construction as specified in the 2012 International Fire Code.
- If fire hydrants are located on private property the following note must be shown: "Where property is privately owned, thrust blocks for fire lines must be inspected by the Fire Marshal prior to back-filling trenches. The plans should have a note indicating the above requirement as well as a note to call the Fire Marshal's office at (678) 493-6290 for this inspection."
Water Availability Notes
- All water lines serving a hydrant must be a minimum of 8-inches in diameter and constructed of ductile iron pipe or C900 PVC as approved by the Water and Sewer Authority.
- Water Flow Test Results are required to be listed on the plans. The Cherokee County Water and Sewer Authority Requirements establish the minimum flows for commercial developments.
- Structures with sprinkler systems must show vault, Fire Department Connection (FDC), and valve location details. The FDC must be located away from the building structure near a truck entry point.
STREET DESIGN REQUIREMENTS
The minimum paved street width is 24-feet before curb and gutter as shown in the Cherokee County Development Regulations (CCDR) Section 4.05.A.3.H. One-way single lane streets require a minimum of 12-feet paved before curb and gutter. Although 12-foot lanes are allowed by CCDR, the 2012 IFC may require 20-foot roads in some cases. On the plans, show all street widths and clarify if the measurement shown is strictly pavement width or width from back-of-curb to back-of-curb. The figures listed above meet state adopted 2012 International Fire Prevention Code minimum requirements.
- Provide parking space dimensions and driveway aisle widths throughout the parking lot.
- Cherokee County Standard Parking Detail 209 requires that 90-degree angled spaces maintain a 24-foot wide aisle.
- The minimum allowed access road or parking lot aisle in the International Fire Code is 20-feet.
Development entrances and main intersections require a turning radius of 40-feet as listed in the Cherokee County Development Regulations section 4.05.A.3. When the entry street intersects a state road, the DOT might require a different turning radius that does not meet county minimum standards. This situation will need to be documented on the plans. Internal parking lots are required to have turning radii of 25-feet.
- An approved turnaround for fire apparatus vehicles must be provided at dead end streets. The Cherokee County Development Regulations provide a Standard Detail 205, which shows the approved cul-de-sac dimensions. A 60-foot minimum radius is required.
- Dead-end fire apparatus access road(s) exceeding 150-ft in length must be provided with an approved method for turning Fire Department vehicles around as required by the International Fire Code Section 503.2.5 and the Cherokee County Development Regulation Standard Detail 205.
Building Structure Features
- Utility service equipment must meet the protective guidelines of the National Fire Prevention Association.
- Transformers must be shown 10-feet or more from building structures and 14-feet from doors.
- Bollard protection must be shown around transformers and utility meters when located beside driveway areas.
- Building separation must comply with the 2012 International Building Code Table 602. Indicate on the plans the distance from the building structure to the property line. If less than 30-feet, fire rated building materials must be specified if needed. In the event that unlimited area provisions are needed, 60-feet to the property line may be required.
- Provide room for a 4-foot wide sidewalk or landing around the building. This is required for both exit and access doors. GA Amendments 120-3-3 IFC Section 5 requires access doors every 100-feet along access drives.
Fire Protection Features
- An all weather Fire Department access road with a minimum width of 20-ft. must be provided within 150-ft of all portions of the 1st floor of the proposed building(s) as required by the 2012 International Fire Code Section 503.1.
- Fire Lanes (No Parking Zones) are required around portions of the building(s) and hydrants to prevent blockage of Fire Department apparatus access. These must meet both the sign and marking specifications listed in the 2012 International Fire Code.
