Comments from GIS Division/Address & Street Name Management
Project Address
Overall Project Site address is approved as 349 Military Cutoff Rd. Individual buiding and unit addresses will be assigned upon release for construction of this project.
Development Name
The development name Carroll at the Avenue is approved for use for this development.
Street Names
Any public street or private drive which is more than 200 feet and serves as the primary means of ingress/egress for a minimum of 4 homes/dwellings or 12 commercial structures, will be required to have a street name. The development has 3 private drives/roads which require an approved street name. Please submit 6-8 names for review as soon as possible.
All street names must be approved by the City of Wilmington. Proposed street names should be submitted to one of the following City employees for approval:
Once the names are approved, they will be placed on a reserve list to be used for Carroll at the Avenue
Approved street names must be properly labeled on all final construction plans and final plats submitted to the City. Failure to properly label the names may result in the re-submittal or re-recording of a construction plan or plat.
Street name signs for public and private streets must be erected before a Certificate of Occupancy is issued. Contact Traffic Engineering at 910.341.7888 for information about street signs for this project.
Street names may not duplicate, sound-alike, or be similar to any other street name or development name in New Hanover County (Addressing Standards and Procedures, Section 2.2.5).
Street names must be a minimum of three (3) characters and a maximum of twenty-four (24) characters in length (Addressing Standards and Procedures, Section 2.2.1 and 2.2.2).
Street names should avoid the use of special characters, such as hyphens, apostrophes, or periods (Addressing Standards and Procedures, Section 2.2.3).
Street names should avoid the use of words or syllables that may be confused with directional or street type designations (i.e. Northglen Dr or Circle Dr) (Addressing Standards and Procedures, Section 2.2.4).
Continuous streets passing from one existing subdivision to a new one should continue the same name (Addressing Standards and Procedures, Section 2.3.4).
The Addressing Standards and Procedures Manual for the City of Wilmington and New Hanover County can be found online by clicking here. Please reference this document for additional information about street suffix usage (Section 2.4.1) and other details or rules regarding street naming and addressing.
Final dwelling/unit addresses
Individual dwelling and/or unit addresses will be assigned upon final site plan approval and will be based on approved street names.
Lot or unit numbers should be labeled on site plan. Lot numbers shown on site plan should not be used as unit/dwelling address.
It appears with the mixed use structures there are FDC’s missing and notes pertaining to sprinkler systems. Please address the following:
- Show all FDC locations on the plan.
- FDC must be on the front of the building unless otherwise approved.
- Fire Hydrants to be installed per City of Wilmington ordinance and CFPUA Standards
- Water flow analysis may be required to determine the correct water main size to meet sprinkler system demand and fire flow requirements due to the size of the project.
- Standpipe(s) will be required because the floor elevation is greater than 30' above the lowest level of fire department vehicle access.
- The type of Building Construction according to the International Building Code must be present on the plans.
Please add the following to the Fire & Life Safety Notes:
- New hydrants must be brought into service prior to combustible materials delivered to the job site
- A hydrant must be within 150' of the FDC (measured as the truck drives for practical use)
- FDC must be within 40' of fire apparatus placement
- Additional fire protection and/or accessibility requirements may be required due to any special circumstances concerning the project.
- Private Underground Fire Lines require a separate underground fire line permit from the Wilmington Fire and Life Safety Division 910-343-0696
- Contractor shall submit a Radio Signal Strength Study for all commercial buildings that demonstrates that existing emergency responder radio signal levels meet the requirements of Section 510 of the 2018 NC Fire Code.
