Gresham's parking lots run a high mix of suburban retail strips along Powell Boulevard and Burnside Road, MAX-station park-and-rides, and aging commercial pads on Division that need channelization upgrades during recoats. Cojo installs delineators across the city tuned to pavement age and traffic mix rather than ordered off a catalog default.
The 60-word direct answer: Cojo installs delineators on Gresham parking lots, drive-thrus, and pickup zones per MUTCD Section 3F.04 color rules and Gresham Community Development Code site-plan review. Standard spec is engineered urethane flex posts on surface-mount spring bases with ASTM D4956 Type IV retroreflective sheeting. Project sizes run 8 to 50 stations.
Three Gresham-specific factors shape most projects.
Color rules per MUTCD Section 3F.04: white on the right of travel, yellow on the left, blue at hydrants. Sheeting type per ASTM D4956. NCHRP 350 or MASH crash-test compliance for posts near public streets.
Gresham's Community Development Code treats parking-lot channelization as part of site-plan review. Lots connecting to a public street require staff review of circulation and accessible-route geometry; Cojo handles the spec submittal.
ADA Std 402 and ADA Std 307 protruding-object rules apply on any lot with accessible parking. Posts inside an accessible route must have cane-detectable bases or sit fully outside the 27-to-80-inch protruding-object zone.
Standard parking-lot spec for Gresham, with anchor adjustment for mature pavement:
Mature-pavement chemical-anchor spec adds $4 to $9 per post in material cost relative to wedge anchors but extends installation life from 5-to-7 years to 10-plus years.
Same-week mobilization on jobs of 8 posts or more is the norm.
Standard crew throughput, with mature-pavement adjustment:
A 22-post job typically completes in 1 to 1.5 shifts on aged Gresham pavement vs 1 shift on newer pavement.
Most parking-lot work does not need a separate permit because parking lots are private. Exceptions:
Cojo handles permit coordination on projects that require it.
Cojo installs delineators across Gresham parking lots, drive-thrus, and MAX-corridor commercial properties per MUTCD spec and Gresham site-plan review. Aging pavement gets chemical-anchor spec; newer pavement gets standard wedge anchors. Contact Cojo for a Gresham delineator install quote.
