Street Improvement Projects

The Street Division utilizes both in-house crews and contractors to complete road improvement projects on the city’s 1,135 lane miles.

Crack seal

Crack Seal seals the cracks in roads to protect from water intrusion and other damaging factors.  This is one of the city’s most cost effective preventative maintenance strategies in reducing asphalt deterioration and prolonging pavement life. 

Crack Seal will be completed in the following subdivisions in 2020:

Amherst, Appleblossom, Arrowhead, Boulevard Plaza, Brittany Oaks, Cheyenne Ridge, Church Ranch, Country Club Highlands, Countryside, Franklin Square, Green Acres, Green Knolls, Harris Park, Huntington Trails, Hyland Greens East, Hyland Village, Kings Mill, Legacy Ridge, Northridge Manor, Prospectors Point, Quail Crossing, Ranch Reserve, Shaw Heights, Sheridan Green South, Shoenberg Farms, Skyland Village, South Westminster, Standley Lake, Stratford Lakes, Sunset Ridge East, Sunstream, The Rach, Trendwood, Vista Village, Warwick Station, Westcliff, Westminster Station and Woodcreek,

Hot applied chip seal

Westminster uses contractors to place a surface treatment that combines a Chip Seal and a thin layer of open graded friction course (rock) providing a double surface.  This process provides a durable surface and waterproof membrane that will improve the existing asphalt.

Hot Applied Chip Seal will be completed on the following streets in 2020:

  1. Simms Street, 100th Avenue to north city limits
  2. 117th Avenue, Wolff Street to Sheridan Boulevard
  3. Wolff Street, 117th Avenue to 118th Place

Slurry seal

The city's contractor, Vance Brothers, Inc, will place slurry seal in three neighborhoods in 2020. Slurry seal is a thin restorative surface treatment that does not require milling and extends the useful life of asphalt by keeping air and water out and stopping oxidation.

Slurry Seal will be completed on streets within the Home Farm, Harmony and The Orchard neighborhoods in that order. Project map.


  • Week of May 18 - Mid-June - Concrete work begins and is expected to take about two weeks in each subdivision. No parking signs and variable message boards will be placed at the entrances to alert homeowners of the work happening in the area. 
  • Mid-June - Asphalt patching will take place after the concrete work is complete.
  • Mid-June - Crackseal will be used to place a final seal at the joints in the roadway. 
  • Mid to late-June - Final slurry seal operations will begin. 

Asphalt paving

A contractor will place a new asphalt surface.  This pavement may be placed either over an existing roadway or on roadways that have received milling operations. Milling is the process of grinding up and removing the existing asphalt surface. Milling may be only at the edges of the roadway or may be the full width of the roadway.

  1. 104th Avenue, Sheridan Boulevard to Church Ranch Boulevard
  2. 80th Avenue, Lowell Boulevard to Sheridan Boulevard
  3. 88th Avenue, Wadsworth Parkway to Harlan Street

Concrete Replacement Program

Street Inspectors have completed the evaluation process and have marked concrete for replacement in 2020.  The areas where work will be completed are shown on this list.  Residents affected by the replacement program will be notified prior to work beginning in front of their homes.  The tentative start date for this work is June 1.   Silva Construction, Inc. will be the contractor working in these areas.
