1.3.47 SCR-47 Traffic Control Plan

In lieu of the traffic plan provided as a part of these contract documents, the contractor may opt to submit an alternative Traffic Control Plan to USACE (SPK) and City of Sacramento for review and approval prior to commencing construction activities. At a minimum, the alternative Traffic Control Plan shall achieve the following objectives:

(1) Two-way bike lanes are to be provided during construction. A two-way bike lane is to be provided by closing off the Garden Highway south east-bound land and will be kept open between Gateway Oaks Drive and Natomas Park Drive during construction phasing. If the bike paths are adjacent to vehicle traveled lanes, then a temporary concrete barrier shall separate the two types of traffic.

(2) The northern entrance to Discovery Park at Natomas Park Drive and Garden Highway shall not be impacted by construction during their three main events. These events have not been scheduled, however they are generally scheduled for early May (Bassmaster Tournament), the second week of September (the California Brewers Festival) and the Third week of October (the Aftershock Music Festival). During construction the Discovery Park entrance will remain open except when the construction of the cutoff wall is crossing Natomas Park Drive. Temporary road reconstruction measures and plating shall be done to reopen the Natomas Park Drive entrance to Discovery Park for vehicle and bike access as soon as possible but no longer than 4 days after the closure of the intersection for cutoff wall construction.

(3) Where feasible, one westbound and one eastbound lane shall be provided on Garden Highway between Gateway Oaks Drive and Natomas Park Drive during construction. In the event only one lane can be kept open (e.g.

when actively trenching on Garden Highway and swing radius of trenching equipment is a concern) a two way, one lane access will be provided on Garden Highway with traffic controls in place.

(4) The contractor shall implement traffic control measures to ensure vehicles exiting I-5 onto Garden Highway do not back up onto I-5.

Full roadway closure between Truxel Rd. and Northgate Blvd. shall not occur until absolutely necessary for progress of the construction of the cutoff wall to continue to end of project.

The fiber optic sensors will be installed in no more than two elements as defined in Specification Section 31 56 13 Slag Cement-Cement-Bentonite Cutoff Wall - Open Trench. The data collected using the fiber optic sensors will not be used to determine cutoff wall acceptance nor will the installation relieve the contractor of any of the requirements of the contract specifications and drawings. The Contractor must allow the installation of the fiber optic sensors after completion of full depth excavation of the cutoff wall element but prior to the initial set of the cutoff wall element. Following installation of the fiber optic sensors, the Contractor shall allow access to representatives of the University of California, Berkley to collect data near the installation location of the fiber optic sensors. Access afforded by the Contractor to representatives of the University of California, Berkeley at no cost to the Government. The Contractor may be requested to assist in lowering the fiber optic sensors into the cutoff wall element using either the long stick excavator or other available excavation equipment at the project site. The estimated time required will be two hours per element. The cost of this item is appurtenant to the Construction of the Project. No additional payment shall be made for allowing access to the site or assisting in the installation of the fiber optic sensor.
