Request City Council approve expenditures up to $3,293,000 for FY2022 pavement management projects.

Approve expenditures in the amount of $3,293,000 to complete pavement management projects in various locations throughout the city. (Hugh Bigalk, P.E., City Traffic Engineer)

The FY2022 pavement management budget includes $3,479,000 in HURF and General Funds in the Engineering Operating budget.  Identified in Table 1 below are the FY2022 pavement management projects.

Table 1:  FY2022 Pavement Management Projects

Item	TOTAL
Asphalt Micro Surfacing	$1,715,000
Asphalt Slurry Seal Application	$1,063,000
Surface Seal	$265,000
ADA Ramp Improvements	$250,000
Total	$3,293,000

On March 17, 2014 and August 25, 2014, the city’s pavement management consultant, APT, presented an update on their pavement management project at which time treatment strategies and funding recommendations were discussed.  During those presentations, the City’s Pavement Condition Index (PCI) of 68.1 was presented to Council.  The city’s PCI has increased by 6.8 points from 68.1 in FY2014 to 74.9 in FY2021 from the inventory of all city maintained streets.  We anticipate the PCI will remain stable in future years based on the pavement management program, the Capital Improvement Program, and the continued development of unimproved roads in the city.

Proposed FY2022 pavement management projects total 92.12 lane-miles of pavement preservation projects.

A description of each preservation type is provided below, followed by a list of roadways or neighborhoods recommended for the designated pavement treatment:
 

1. Micro Surfacing – A product that is commonly used on arterial and collector roads, and is effective at correcting or inhibiting raveling and oxidation of the pavement surface, improving surface friction, sealing the pavement surface, and filling minor surface irregularities and wheel ruts up to 1.25 inches deep.  Micro-surfacing typically lasts 5 - 7 years. 

• 159th Ave from McDowell Rd To Monte Vista Rd
• Indian School Rd from Citrus Rd to Perryville Rd
• Cotton Ln from McDowell Rd to Thomas Rd
• Thomas Rd from Cotton Ln to ADOT ROW
• Sarival / Virginia Ave from McDowell Rd to Pebble Creek Pkwy
• Monte Vista Rd from Sarival Rd to 150th Dr
• Central Ave Van Buren St to EOP
• 158th Ave from Van Buren St to Harrison St (South Bound Only)
• Elwood St from 159th Ave Alignment to Sarival Ave (West Bound Only)
• Elwood St from Sarival Ave to Cotton Ln
• Commerce Dr from Sarival Ave to Cotton Ln
• Cotton Lane from MC-85 to Estrella Pkwy
• Goodyear Blvd from Yuma Rd to Sherman St
• Goodyear Blvd from Estrella Pkwy to Yuma Rd
• 150th Dr from Encanto Blvd to McDowell Rd
• Estrella Pkwy from Lavender Ln alignment to EOP
• Willis Rd from Estrella Pkwy to Mountain Vista Dr

2. Slurry Seal – A mixture of crushed, well graded aggregate (fine sand and mineral filler) and an asphalt emulsion that is spread over the entire pavement with a spreader box attached to the back of a truck.  Slurry seals are commonly used in neighborhoods and are effective in sealing low-severity surface cracks, waterproofing the pavement surface, and improving skid resistance at speeds below 30 MPH.  Slurry seal typically lasts 5 to 7 years. 

• Wildflower Ranch
• Legacy Ranch
• Curtis Commons
• North Subdivision
• Tranquility @ EMR
• Serenity @ EMR

3. Guard Top Ultra Sealcoat – A high performance mineral and fiber reinforced asphalt emulsion blended with polymers and special additives.  Guard Top Ultra sealcoats are commonly used on residential streets with minimal aggregate loss and cracking.   Provides a long lasting rich black color while waterproofing the surface.  Typically lasts 5 to 7 years.

• Centerra
• Medina @ EMR
• Stone Canyon @ EMR
• Terrata @ EMR
