Glenville Rd/St Corridor Traffic Improvements

The Town of Greenwich has decided on a preferred corridor concept and completed the preliminary design of the Traffic Signal Optimization and Intersection Improvements along the Glenville Street/Glenville Road Corridor for a distance of approximately 1,500 feet. Funding for this project is provided under the Congestion Mitigation and Air Quality Improvement Program (CMAQ) with 100% Federal funds administered by the Connecticut Department of Transportation. The Town has selected Milone and MacBroom, Inc. for the design of this project.

The Town conducted the 1^st Public Information Meeting on Wednesday, March 20, 2019 at 7:00 p.m. at the Bendheim Western Greenwich Civic Center, to gain input from the public in order to develop different design concepts. Meeting materials from the 1st meeting are attached.

The Town conducted the 2^nd Public Information Meeting on Tuesday, May 21, 2019 at 7:00 p.m. in the lower room of the Bendheim Western Greenwich Civic Centerto present several design concepts based on the concerns heard at the 1^st Public Meeting. A print out of the Power Point Presentation from the 2nd meeting is attached.

The Town conducted the 3^rd Public Information Meeting on Wednesday, September 25, 2019 at 7:00 p.m. in the lower room of the Bendheim Western Greenwich Civic Center to present the preferred corridor concept based on the comments heard at the 2^nd Public Meeting and correspondence from the public shortly thereafter. Meeting materials are attached.

Preferred Corridor Concept:

Concept No. 1, which has the least ROW impacts and potential for environmental permits, was chosen as the preferred corridor option. It is anticipated that this concept will significantly improve traffic operations and safety along the entirety of the corridor. With this concept, the future level of service (LOS) at each of the intersections, will operate at LOS C or better during the morning and afternoon peak hours. The proposed corridor improvements would be as follows:

A. Glenville Street at Shopping Center Driveway

• Widen the Glenville Street segment from the shopping center driveway to Angelus Drive to provide a longer westbound right-turn lane into the shopping plaza while maintaining parking along the northern edge of Glenville Street. Additionally, provide a dedicated eastbound left-turn lane into Angelus Drive. The proposed widening would be accommodated within the existing ROW with no impacts.
• Provide new sidewalks along the southern edge of Glenville Street.
• Realign crosswalks and reconfigure ramps for Americans with Disabilities Act compliance.
• Install new traffic signal equipment.
• Relocate the parking in front of Brighton Cleaners further south on Glenville Street away from the intersection

B. Glenville Street at Riversville Road

• Extend the raised island on Riversville Road to better control gas station access in and out of the Sunoco gas station.
• Tighten the northeast corner radius to slow down vehicles negotiating the right turn from Glenville Road to Riversville Road.
• Install new traffic signal equipment.
• Maintain the existing WebsterBank entrance-only driveway at Riversville Road.
• Maintain but signalize the existing stop sign controlled Webster Bank drive-through.
• Reconstruct and better define the existing parking spaces along both sides of the east leg of Glenville Road.

C. Glenville Road at Pemberwick Road

• Install a traffic signal at this intersection.
• Widen Pemberwick Road to provide dedicated left-and right-turn lanes. This improvement will result in ROW impacts to the park in the southwest corner of the intersection. 
• Widen the eastern leg of Glenville Road to provide a dedicated westbound left-turn lane and a through lane. 
• Provide sidewalks and new crosswalks to improve pedestrian access at the intersection.
• The proposed geometric improvements would result in the elimination of the parking area in front of Glenville Pizza.

D. Glenville Road at Weaver Street 

• Widen the western leg of Glenville Road to provide a dedicated right-turn lane and an eastbound throughlane. This will result in ROW impacts to the Civic Center ball field.
• Widen Weaver Street to provide dedicated left- and right-turn lanes.
• Provide sidewalks and new crosswalks at the intersection.
• Install new traffic signal equipment. 

Historic Notes:

1. The Glenville Corridor is part of Glenville's National Register of Historic Places (NRHP) District.

2. A historical and archaeological review was performed by the Connecticut Department of Transportation (CTDOT).

3. Foundation remains of the Episcopal Church may be present in the western corner of Glenville Road at Pemberwick Road.

4. CTDOT recommends no adverse effects to historic properties and will be making an application to the State Historic Preservation Office (SHPO) with a no adverse effect recommendation.

5. A Section 4F environmental review is needed due to impacts to the civic center park (~900 square feet of impacts). Public comments regarding impacts to the park will be open for 2 weeks. If there is no opposition, the town will provide a letter indicating that impacts to the recreational resource will be de minimus.

6. Approximately 12 areas have been identified as "high risk," and a Task 110 corridor screening is needed to further assess environmental impacts.

Next Steps: 

The Town is planning to:

• Have the consultant advance the preliminary design plans following review and approval from the Connecticut Department of Transportation.
• Work with the design consultant to reduce portions of the design and reduce costs.
