Street Maintenance and Improvement

Weekly Updates - Week of March 19, 2015


Street paving locations will be posted here when the season kicks off in April.

We are currently working on ADA ramp construction in these neighborhoods:

  • Harvey Park South
  • Barnum
  • University Hills
  • Green Valley Ranch

Concrete/ADA Ramp Program
Starting in 2015, Denver will greatly expand ADA pedestrian ramp construction. 

According to standards set by the ADA, newly constructed or altered streets must contain curb ramps. As a result, Denver’s Annual Concrete Program is prioritizing the installation of ADA pedestrian ramps in all locations where the Street Maintenance Division is planning to do street work and a ramp does not exist. Building ramps before the street work is done saves money, preventing new street work from being damaged by ramp installation. Please refer to the weekly construction update on this page and other information below to track ADA ramp construction in your neighborhood and to learn more about the process.


Because of ecological impact of unpaved alleys and the economic drain of maintaining them, in 2005 Mayor Hickenlooper created a program to pave with asphalt the more than 1000 unimproved public alleys in the City. The program took approximately 6 years to complete with 100 to 200 alleys being paved each year.

Alley Types and Maintenance

There are four kinds of alleys in Denver, and each is maintained differently.

  • Asphalt Overlaid Alleys
    There are about 1,400 asphalt overlaid alleys in the City & County of Denver. These alleys are constructed of concrete with a layer of asphalt over the concrete. The City maintains all asphalt overlaid alleys using treatments as explained in paving options for streets and alleys.
  • Unimproved Alleys
    There are less than 150 undedicated unimproved alleys in the City and County of Denver. There is a program in underway to pave these remaining alleys in asphalt by the end of 2016.
  • Concrete Alleys
    There are nearly 2500 concrete alleys in the City and County of Denver. Public Works maintains the city's concrete alleys using treatments as explained in paving options for streets and alleys.
  • Asphalt Alleys
    When the Unimproved Alley Paving Program is complete there will be approximately 1000 asphalt alleys. Public Works maintains these alleys using treatments as explained in paving options for streets and alleys.

Sidewalks

City ordinances establish that abutting property owners are responsible for installation, repair, and maintenance of all sidewalks within the public right-of-way in the City of Denver. If requested, the City will inspect sidewalks and if they are found to be in need of maintenance, notify property owners of their responsibility to arrange for repairs.

Curb and Gutter

The City of Denver is responsible for the maintenance of all curbs and gutters along public streets in the City. In those areas where no curbs exist, the City will require developers to install curbs if property development/redevelopment is occurring, or in select cases, the City may install curb lines as part of other capital maintenance activities. In instances where sidewalks and curbs have been constructed as one unit, the City will make an assessment if any needed repairs are the responsibility of the City or the abutting property owner.

The majority of curb repairs made by the City are in conjunction with other projects such as paving operations or utility work. This helps to provide a higher quality project and fewer construction disruptions to any specific street. A citizen may request an inspection and ‘spot’ repair, but these will be made only if a public safety issue is discovered. Repairs to normal aging will be deferred until that entire neighborhood is scheduled for pavement rehabilitation.


Sidewalk Reporting Policy

Damaged sidewalk complaints must be submitted with a verifiable requestor name, address and phone number. If you wish to remain anonymous, contact your City Council representative to report the issue on your behalf.

  • The City allows one complaint per year per complainant and will not accept lists of complaints or multiple addresses. 
    Contact Right of Way Construction at 303-446-3469
  • All anonymous complaints with an appearance of harassment or discrimination will be discarded and similar new ones will not be accepted.


Street lights in the City of Denver are maintained by Excel Energy. Any street light problems should be reported to them using their "Street Light Outage" form. 


Street Light

Street Lights or Street Lamps come in a variety of shapes, styles and sizes, but in general, the term refers to the lights that are on the sidewalks or the sides of streets and shed light on the right-of-way.

Traffic Light

Sometimes referred to as a "Traffic Light" or "Stop Light", these are the red, yellow and green lights that direct traffic at intersections. The correct term for this type of light is "Traffic Signal" or "Illuminated Traffic Signal".




New street or alley light request

Every year, Denver Public Works engineers prioritize the City's paving needs and create a paving plan for work to be completed. Street Maintenance wrapped-up the 2014 paving plan in November!

Treatment for Roadways

  • Hot-In-Place-Recycle (HIPR) heats the top inch of existing asphalt pavement and mixes this with new asphalt. This process is less expensive and more environmental friendly than mill and overlay and provides a pavement that will last 8 to 10 years
  • Chipseal and the related Capeseal are minor surface treatments, relatively inexpensive, that seal and restore the surface of a pavement and adds 6-8 years of life to a pavement
  • Mill/Overlay is a major process where typically the top 2" of pavement are removed by grinding and replaced with new asphalt. This process adds approximately 12 years to the life of a pavement
  • Major Machine Patch crews cut out section of the roadway for repair anywhere from 50' to 200' long and 10' to 30' wide and 8" deep and apply 7 tons or more of asphalt for repair


Potholes and sinkholes may have similar appearances but their causes are different. Both are deformations in the pavement that collect water, can be jarring to hit, and in extreme cases, cause damage to our cars.

Potholes

Water, freezing temperatures and vehicle loads can combine to break apart the surface of a pavement. These can rapidly develop into potholes that range in severity from a nuisance to a significant safety problem. Street maintenance has crews that are out daily as weather allows looking for and patching potholes. In warm weather most potholes are patched with hot asphalt, but in winter months the potholes are patched with temporary cold asphalt to make the street safe until warm weather allows for a more permanent repair.

Sinkholes

Occasionally a problem will occur beneath a street where soil washes away. This usually occurs when a break occurs to an underground pipe. The pavement will settle into the void, creating a sinkhole. The initial appearance of a sinkhole is similar to a pothole. Street Maintenance and other agencies will investigate all suspected sinkholes for underlying problems and then perform a permanent repair to utilities if warranted and then the pavement.

Sidewalks

City ordinances establish that abutting property owners are responsible for installation, repair, and maintenance of all sidewalks within the public right-of-way in the City of Denver. If requested, the City will inspect sidewalks and if they are found to be in need of maintenance, notify property owners of their responsibility to arrange for repairs.
