Street Conditions Part 1 – State of the Streets Part 2 – Repairs and Maintenance Costs Part 3 – Options for Funding
Street Conditions Part 2 - Repair and Maintenance Costs
Pothole Repair Temporary fix Clean out loose material Cold patch asphalt Larger holes require dig-out
Crack Sealing Blow out crack Apply asphalt sealer $ 1/linear foot Not cost effective for streets Keeps water out of subgrade
Slurry Seals Clean pavement Apply thin asphalt emulsion, sand slurry $0.20/ft 2 Service life 3-5 years
Dig-outs Dig out hole to base material Fill with hot mix Pavement has failed structurally Service life 25 years $5/ft 2
Overlays Grind existing gutter edge Pave with 1 ½ - 2” hot asphalt $1.10/ft 2 Service life 15-20 years
AC – asphalt concrete $1.10 /ft2 Willow St. ARHM – asphalt rubber hot mix $1.80/ft2 S. Montgomery St.
Other: Striping Single white line Yellow and double- yellow Crosswalks Parking spaces Fog lanes Bike paths
Pre-2006 Pavement Management Program Emergency repairs only Limited Caltrans maintenance work on SR 150 and SR33 in city limits Maintenance staff positions cut Minimal preventative maintenance since 2003
Pavement Condition Index (PCI) What is it? Computerized quality rating 0- 100 0 no structural stability, very deteriorated 100 new street How is it calculated? Type and percentage of cracks, thickness of pavement, condition City has 147 road segments. Average PCI Citywide is 48 Other Cities Try to Maintain +/- 65
Current Street Conditions 0-20: 21 segments 21-40: 33 segments 41-60: 40 segments 61-80: 39 segments 81-100: 14 segments
Identifying Need Scheduling Repairs Pavement Condition Index (<20) Traffic Volume (increased volume = decreased street life) Truck traffic 06-07 $400,000 budget (includes 5 years of STP funding)
San Francisco/Bay Area Transportation Commission
Repair Costs Estimated repair cost $8 million Reconstruct or overlay Assumes PCI=65 Assumes maintenance budget is provided.
Five-Year Pavement Improvement Plan Repair cost $1.6 M annually for five years plus $80K maintenance Some emergency repairs will be needed before five years. Assumes City = PCI 65
Recommended Annual & Preventative Maintenance Program Striping – ½ city/year$15,000 Slurry seal – 5 year intervals$50,000 Crack sealing – not recommended Pothole Repair – As needed, requires reinstatement of maintenance personnel plus materials $15,000 ( material only)
Caltrans Maintenance Contract $74,000 contract to perform maintenance on SR 150 and SR 33 in the City limits Better knowledge of City needs Fast response time Limited by reduction of PW maintenance staff
Proposed 06-07 Street Improvements Cuyama (SR33-Church) 54250 ft 2 Cuyama (Church-Del Norte) 41040 ft 2 Palomar (Bristol-Cuyama) 26280 ft 2 El Paseo (Bristol-Cuyama) 6520 ft 2 Canada (SR150-McKee) 102160 ft 2 Vista Hermosa (Foothill-Del Oro) 19680 ft 2 Fulton (SR150-Grand) 72720 ft 2
