Annual Street Program


The purpose of the street program is to prolong the life of City streets.  The City of Gahanna has 325 lane miles of roads that require regular maintenance to keep them in a condition that is safe for travel.  Gahanna experienced a boom in residential development over the past 25 years which has almost doubled the amount of residential streets.  The annual cost of street maintenance has increased in proportion to this growth.

Frequently Asked Questions

The Service Department is responsible for rating the condition of all City-maintained streets.  This is completed annually.  For rating purposes, streets are divided into three categories as follows:

Residential (Composite): consists of 3-inch asphalt layer on top of a 7-inch concrete base with a separate curb and gutter

Residential (Detroit): a concrete street where the curb, gutter and street base are poured as one unit (some of these concrete streets have had a 3-inch asphalt layer applied in an attempt to extend the lifespan of the street)

Arterial: consists of 2-5 lanes and carries most of the traffic into, out of and through the city

The overall rating of a street is called the Pavement Condition Rating (PCR).  The rating system is based on a scale of 0-100 (100 being excellent condition).  The following criteria determine a street’s PCR: extent of cracking, concrete condition, crack seal condition, and pavement defects (ie: potholes, ride quality, etc).  Each contributes to the overall rating; however, pavement defects are weighted the heaviest because it relates to ride quality and maintenance costs.  Industry standard is for streets to rate above 75.

When a new residential street is built, it typically consists of a 3-inch asphalt layer (pavement) on top of a 7-inch concrete base with a separate curb and gutter.  The street is estimated to last 25-30 years before needing rebuilt.  One way to assure streets meet this target lifespan is to utilize proper preventative maintenance applications that extend the life of a street.  These applications include crack seal, microsurfacing and overlay.

Crack Seal
Crack seal is a temporary preventative maintenance application applied to a street when minor cracks become pronounced throughout the pavement surface. This technique fills moderate sized cracks in the surface. This reduces the penetration of water and ultimately aids in extending the lifespan of the asphalt pavement. During this treatment debris is cleaned from the cracks with compressed air and a hot sealant is applied into and across the crack. This treatment is a moving operation so traffic is maintained at all times except in the immediate vicinity of the crack sealing operation.

Microsurfacing is a temporary preventative maintenance application applied to a previously crack sealed street when the pavement surface begins cracking to the extent that the existing crack seal is no longer suitable. This technique spreads a thin layer of surface treatment over the existing pavement. The material consists of small gravel, an asphalt binder and additional additives. The microsurface binds to the pavement to protect it from sun, snow, rain and damage from vehicles and ultimately aids in extending the lifespan of the asphalt pavement. The rough surface is hard-wearing which promotes traction and prevents slipping. When the material is first applied it may appear brown in color and very course. Over several weeks it will appear more black in color. Travel on the street is prohibited while the material cures which typically takes three to four hours.

When the pavement surface has reached the end of its useful life, the deteriorated asphalt layer is removed and replaced. This is also known as overlay, resurfacing or paving. This technique removes, or planes, the top 3-inches of the existing pavement and installs a new structural layer of asphalt. It may be up to 10 days after the planing occurs before the new asphalt surface is installed while repairs are be made to the base pavement. Sections of deteriorated curb may also be identified for repair and curb ramps are made ADA-compliant if not already in that condition. Curb repairs in front of driveways will require time for the newly placed concrete to cure before it can be opened up to vehicles. Traffic is maintained throughout the treatment, but driveway access may be restricted for up to 7 days while curb repairs are completed. This treatment will provide a smooth pavement surface which should yield 25 to 30 years if properly maintained.

When other treatments are no longer cost effective, the pavement is reconstructed. The existing pavement is removed entirely and new pavement is installed. This includes the 3-in asphalt layer along with the 7-inch concrete base. Reconstruction typically includes new curbing and the partial removal and replacement of driveway approaches. Curb ramps at intersections will be made ADA-compliant if not already in that condition.

The following is the preventative maintenance cycle currently used to maintain residential streets.  The cycle determines the next application to be performed considering the previous treatment for any given street.  The 3 types of preventative maintenance applications are repeated until treatments are no longer effective after which the street is rebuilt.


Please report all potholes to the Service Department at 614-342-4005.

Dead Animals
The City will pick up dead animals Monday through Friday, between the hours of 7:00 am and 3:00 pm, that are in the City's right-of-way.

Snow and Ice
The City is responsible for clearing roadways and bridges. Property owners are responsible for their sidewalks, driveways and driveway approach. The City will clear main streets first, then secondary roads and finally courts. If you are experiencing a weather related problem with the roadways (i.e. icy intersection), call 614-342-4005, Monday through Friday, 8:00 am - 5:00 pm. After 5:00 pm and on weekends and holidays, call 614-342-4240.

Signage Issues
The City erects and maintains all signage in the right-of-way (i.e. stop, no parking, street names, etc). Please report any damage to signage. Call 614-342-4005, Monday through Friday, 8:00 am - 5:00 pm. After 5:00 pm and on weekends and holidays, call 614-342-4240. If a stop sign or any potentially dangerous signs are down, please call the police at 614-342-4240 anytime.

Traffic / Pedestrian Lights
The City is responsible for maintaining traffic lights, Street lights and pedestrian crosswalk lights. If a traffic or pedestrian crosswalk light is out or not working correctly, please notify the City. Call 614-342-4005, Monday through Friday, 8:00 am - 5:00 pm. After 5:00 p.m. and on weekends and holidays, call 614-342-4240.

Mailbox Standards
The U.S. Postal Service (USPS) regulations require residents to provide and erect at their own expense mailboxes which meet USPS official standards.  The front mailbox and door are to be 6 inches behind the back edge of curb and 38-42 inches above the ground.  If these guidelines are followed it will ensure that the City plows will not physically hit the mailbox.  If your mailbox is damaged by a plow or by the force of snow pushed off the plow, please contact the Service Department at 614-342-4005.  In addition, property owners are responsible for clearing snow from in front of their mailbox so delivery is not interrupted.
