Roadway Improvements Site for Granite Creek Road and Branciforte Drive

Welcome

Welcome to the 2018 Santa Cruz County Department of Public Works Roadway Improvements Site for Granite Creek Road and Branciforte Drive being built by Granite Construction.

This site is intended to keep the public informed and updated as construction crews work to improve the condition and longevity of these roadways over the course of the summer and fall of 2018

Schedule updates are located by street name at the links below.

Summary of Roadway Enhancements

Granite Construction has been selected as the contractor to improve the condition and drivability of these county roads. These improvements include cleaning and enhancing roadside ditches to maintain drainage off the road shoulders, the removal and replacement of many culvert crossings to improve drainage flows under the new roadway, pulverization and re-grading of the existing roadway to remove current irregularities and create a smoother more predictable driving surface, application of cement into the pulverized base course to improve strength and uniformity of subgrade and replacement of asphalt paving and roadway striping. For specific information on either road visit that link.

Why Full Depth Recycle?

Santa Cruz County has selected to use a method referred to as Full Depth Recycle (FDR) to restore these deteriorated roadways. FDR involves reconstructing existing distressed pavement sections by in-place recycling of the existing materials and treating with Portland cement to enhance the structural properties of the recycled materials to create a strengthened base for a new paved surface. Cement and water are added to the pulverized material, thoroughly mixed and compacted to create a uniform surface. Benefits to using FDR instead of removal and replacement include, recycled base will be stronger, more uniform, more moisture resistant (than the original base). Not only is the product superior to the original but recycling costs are considerably cheaper than the removal and replacement of the old surface. Recycling saves money and natural resources!

Traffic Control, Working Hours, Closures and Detours

Traffic control will be required to separate the public from the hazards associated with construction activities. Most construction activities will require single lane closures managed by flaggers. Delays of approximately fifteen minutes should be anticipated. Standard work hours will be from 8:30 a.m. until 4:30 p.m. Monday-Friday with minor deviations possible. It is probable that periods of full road closures will occur during the time of milling, FDR and paving. Machines used for these operations occupy more space than allow for safe passage in an adjacent lane. During times of road closure residents will be allowed passage as far as practicable. Residents will be notified via “door hangers” three days prior to any planned closures. Detours will also be set up to notify the public of the activity. Closures will also occur between the hours of 8:30 a.m. until 4:30 p.m. Monday-Friday with minor deviations possible. Granite will also be posting “Temporary No Parking” signs along the streets where parking could occur two days prior to commencing re-surfacing.
