Subject: 	118 Congress Street - Final Traffic Comments

Jean ‑ The following is a status update of my December 12, 2013 comments and represent my final comments.

*        The project will be providing in excess of one parking space per residential unit and therefore meets City     standards.

Status:  I would note that per zoning standards, parking provisions for the commercial uses are not required and thus the project only provides parking for the residential use.

*        I find the proposed driveway condition to be acceptable.  The project will be eliminating two curb cuts 	 on Congress Street and providing one driveway on St. Lawrence Street.

Status: No comment necessary.

*        Some of the parking spaces on site do not meet City standards (reduced size ‑ but larger than compact size spaces) and a waiver will be required.  A formal waiver and supporting information shall be provided by the applicant.

Status: In addition to the request for a parking stall dimension waiver, the applicant is also requesting a waiver for a reduction in parking aisle width from 24 feet to 23 feet.  I support waivers from these City standards.

*        In my professional opinion the proposed project will not generate a significant amount of traffic and is not expected to have a negative impact on traffic safety and operations in the study area.

Status: No comment necessary.

*        Historically a crosswalk has been provided on Congress Street at the easterly side of the St. Lawrence Street intersection.  The City's Crosswalk Committee shall review the subject location and identify recommendations for installing a crosswalk.  If deemed appropriate by the Crosswalk Committee the applicant will be responsible for installing the crosswalk and all supporting features.

Status: A condition of approval should be included that notes if a crosswalk is required by the City's Crosswalk Committee the applicant will be responsible for implementation of all features of the crosswalk including but not limited to pavement markings, signage, and ADA compliant ramps.

New Comments

*       Changes in on‑street parking regulations will be required as a result of the project.  Accordingly changes to the City's Traffic Schedule will be required, thus requiring City Council action. The applicant will be responsible in providing materials in support of the Council request packet.

*       Deliveries and services vehicles for the project will be expected to do so from the street. The applicant shall coordinate with the Parking Division and the Department of Public Services for the type of on‑street regulations to be implemented on Congress Street along the project frontage.  The applicant will be responsible for all costs associated with signage installation.

*       I have reviewed the construction management plan provided by the applicant and I find the general concept to be acceptable.  Specific comments are noted below:

o   All temporary sidewalks and crosswalks will need to be ADA compliant.

o   Further detail will be required for determining the safest location for a temporary crosswalk on St.  Lawrence Street. This includes sight distance and driveway locations, at a minimum.

o   The applicant will be responsible for winter maintenance of the temporary facilities as well as along the public street abutting the detour on Congress Street.

o   The details of the delineator posts need to be further reviewed.

o   The contractor will be responsible for work including signage and pavement markings and work must meet requirements of the Manual on Uniform Traffic Control Devices.

o   A schedule of activities should be provided and documentation on the need for sidewalk closures, in terms of duration, shall be provided.

o   The applicant shall be responsible for submitting a Construction Management Plan for review and approval prior to the issuance of any City Permit.

If you have any questions, please contact me.
