Subject: 	122 Anderson Street

Jean ‑ I reviewed the application materials for the project and offer the following final comments and conditions of approval for the project.

*       The applicant has suggested a routing plan from 122 Anderson Street to Fox Street and Franklin Street. I find this routing to be reasonable given the driveway geometric alignment (left‑turn exit movements and right‑turn entry movements would be problematic).  Accordingly, the following recommendations are based upon this routing.

*       Based upon the limited number of trucks being generated by the project during the typical 	commuter peak time period and that trucks will be metered into the streets system, as 	recommended below, a traffic impact study is not recommended.

*       Based upon my intimate knowledge of the Anderson Street/Fox Street intersection, temporary 	enhancements to the intersection should be implemented by the applicant in advance of 	the 	permanent improvements expected to be constructed later this year. These improvements 		shall include the following and a plan shall be provided for review and approval before 	installation occurs. It should be noted that this intersection will be under 	construction beginning 	later this summer and thus some of these temporary measures may be impacted.  The 	applicant shall be responsible for maintaining these items throughout the Nova Star 	trucking season.

o   	A crosswalk shall be painted on the westerly Fox Street approach.  The crosswalk shall 	be aligned with the apex on the southwest corner of the intersection and the Coffee By 	Design 	Driveway on the northwest corner (half of the crosswalk would be in the 	driveway).

o   	A crosswalk shall be painted on the easterly Fox Street approach. The crosswalk shall be 	aligned with each corner apex.

o   	STOP bars shall be re‑painted on the eastbound Fox Street approach and the southbound 	Anderson Street approach.

*       The number of trucks entering or exiting the site over a delivery day time period (trucks arriving 	in advance of ship departure during the day and leaving the site to get to the ship) shall be limited 	to 15 trucks during 2014 operations. Following the results of the monitoring study, the number of 	trucks may be increased to a maximum number of 30 trucks either entering or exiting the site 	over a 24‑hour period. It should be noted that the monitoring study shall include all 	roadways/intersections between 122 Anderson Street and the Ocean Gateway site.

*       The applicant shall fund a traffic monitoring study to be conducted by the Planning Authority. 	The monitoring study shall be conducted within two weeks after operations begin and at a later 	date in the 2014 season. The monitoring study will ensure the conditions noted are being met and 	to identified any issues that may need resolution.  If the monitoring study identifies safety 	concerns, the applicant shall be fully responsible for implementation.  It is anticipated that 	possible mitigation actions may include additional warning signs and pavements marking, traffic 	signal modifications at intersections along Franklin Street, truck arrival/departure management, 	and route adjustments.
*       The applicant shall implement a departure management plan that limits the truck departure rate to 	a one truck per minute or more. The westbound Fox Street signal phase at Franklin Street will not 	likely be able to process more than one truck and therefore is currently a limiting factor.  The 	monitoring study will review this departure rate and recommend adjustments, as necessary.

*       The applicant shall install truck entering warning signs at the site driveway that are compliant 	with the Manual on Uniform Traffic Control Devices, Federal Highway Administration. 	Final 	details of signs shall be reviewed and approved by the Planning Authority.

*       Driveway access/egress conditions for both site driveways shall be monitored at the initiation of 	operations.  Currently, Tandem Coffee and Bunker Brewery use both driveways and this will 	continue in the future.  If deemed necessary, from the monitoring study, on‑site circulation and 	access provisions will need to be formally regulated and controlled.  An outcome of the 	monitoring study could be that the northerly driveway (with the truck scale) be used for trucks 	and employees only and the southerly driveway be used for Tandem Coffee and Bunker Brewery 	customers and the Community Center. Changes may require both regulatory and wayfinding 	signage and the applicant would be required to propose how to physically separate the two 	driveways, internally, so that vehicles are controlled.

*       The applicant shall be responsible for providing a fully paved driveway of a minimum width of 	22 feet wide from the right‑of‑way boundary extending into the site for  50 feet. A plan of this 	improvement shall be provided for review and approval.

If you have any questions, please contact me.

Agreed – they do not need to prepare a plan.  I need to discuss this with Kathi tomorrow.  She has been on vacation
