Traffic and infrastructure do not conform to neighborhood boundaries. While certain roads or areas may experience the most visible effects of congestion, the transportation system operates as an interconnected network. When major corridors such as Route 1 become overburdened during peak travel periods, the impacts are distributed throughout the town. The central issue is not simply proximity to a particular location, but how Westwood’s road network responds to congestion and redistributes traffic flows. As Route 1 becomes congested, drivers are pushed onto alternate routes, including residential streets. 

These impacts can include:

• Delays in emergency response times

• Disruptions to school bus routing

• Reduced access to critical town services and community resources for Westwood residents, including:  schools, polling locations, town hall, police, sports fields, libraries, and the senior center, with impacts on daily mobility, civic participation, and quality of life

• As pressure on the primary corridors increases, traffic is often redirected onto secondary and residential streets including: Smith Drive, Pine Lane, East Street, Everett Street, Canton Street, Forbes Road, Carroll Avenue, Gay Street, Fox Hill Street, Thatcher Street, Milk Street, Washington Street, Clapboardtree Street, and Nahatan Street, as drivers seek alternative paths through the network 

As a result, congestion impacts are not confined to a single roadway but are distributed across the broader transportation system, with varying levels of intensity throughout the town. 

Large-scale developments can place additional demands on municipal services, even if the project is not located in Westwood, as impacts from Costco will still require Westwood to allocate public resources. These include: 

• Increased need for Westwood police traffic enforcement 

• Greater Westwood fire and EMS response complexity, including traffic-related incidents

• Potential infrastructure upgrades in the town of Westwood is funded through our public resources (traffic studies for new traffic patterns, etc.)

• Additional cut-through traffic, congestion, noise, and safety concerns can change the character of residential areas and may influence how residents and prospective buyers perceive those neighborhoods over time. These quality-of-life impacts could contribute to reduced neighborhood desirability and, potentially, downward pressure on property values. 

These impacts are not isolated to a single neighborhood. They extend across Westwood and may require the town to dedicate additional public resources, including municipal services, staff time, infrastructure planning, and taxpayer-funded investments. While the direct benefits of the development accrue primarily to Norwood and Costco, the potential costs may extend beyond Norwood's borders, leaving Westwood residents to absorb impacts through increased demands on local services, municipal resources, and the potential degradation of neighborhood quality of life. 

The project would generate no direct tax revenue for the Town of Westwood, as the site is located entirely within Norwood. At the same time, Westwood residents would likely experience significant fiscal impacts from the substantial increase in vehicle traffic associated with the development.

These impacts may include:

• Increases in taxes due to an increase in traffic enforcement & emergency services

• Higher home insurance and car insurance premiums for our zipcode

• Lower home values (less tax revenue for Westwood)

As a result, Westwood could bear many of the burdens associated with the project without receiving corresponding municipal benefits.

The property was originally approved for laboratory and research uses, not large-scale destination retail. On April 14, 2026, the Norwood Zoning Board of Appeals (ZBA) approved a change-of-use permit allowing the property to be used for retail trade, service, and vehicular service. This is more than a change in zoning classification. It represents a fundamental shift in how this property functions within an established neighborhood, changing the daily experience of residents and the character of the surrounding community.

Laboratory and research facilities generally operate during standard business hours and primarily serve employees. Traffic is concentrated around the beginning and end of the workday, with relatively limited activity during evenings and weekends. A regional warehouse retailer operates on an entirely different scale. It is designed to attract a continuous flow of customers throughout the day, with peak activity occurring during evenings, weekends, and holidays, precisely when residents are most likely to be driving, walking, biking, or spending time outdoors.

That change affects far more than traffic volumes. It changes the daily experience of the surrounding neighborhood. Streets that residents use to walk dogs, ride bicycles, jog, or allow children to play outdoors will experience heavier traffic, more turning movements, longer queues at intersections, and increased cut-through traffic as drivers seek to avoid congestion. Crossing local roads becomes more dangerous, neighborhood streets become busier, and the character of the area shifts from a primarily residential neighborhood to a regional shopping destination.

Costco's operating model intensifies these impacts. Unlike a traditional retailer, Costco draws customers from multiple communities and offers services including a warehouse retail store along with services such as tire sales and installation; optical exams and eyewear sales; hearing testing and hearing aid sales; food preparation and sales; meat preparation and sales; bakery operations and baked goods sales; alcohol sales; a gas station; pharmacy services; and a food court. These features increase both the number of trips and the amount of time customers spend on site. The resulting traffic patterns are more comparable to those of a small regional shopping center than a typical commercial business.

The effects would not stop at the property line. Increased congestion, traffic diversion, and additional pressure on major roadways would affect travel throughout Westwood, while the neighborhoods closest to the site would experience the most immediate changes in noise, traffic, and daily activity. This is not simply a new commercial tenant. It is a fundamental change in the intensity of the property's use and in the character of the surrounding area.

Even residents who live farther from the project site have a vested interest in maintaining overall community conditions. This includes:

• Preserving predictable traffic patterns

• Limiting regional congestion that affects daily travel

• Access to Route 128 train station/University shopping center

• Access to the senior center, sports fields, and schools

• Protecting property values tied to town character, schools, and livability

In suburban communities, quality of life is interconnected and depends on the stability of the overall environment, not just individual neighborhoods.

The approval of a high-impact development of this scale in a neighboring community can influence future development decisions beyond the immediate site. Large regional retail projects can become examples for other communities considering similar proposals, gradually shifting expectations about the appropriate intensity and scale of commercial development near established residential neighborhoods.

While one project alone may not transform a region, a pattern of approving increasingly intensive uses can reshape traffic conditions, neighborhood character, and the balance between commercial and residential areas. The impact of these decisions extends beyond nearby residents and helps define future growth patterns across the region.
