Traffic Analysis City Report

Traffic Analysis City Report

Here is a section from the City report that talks about key intersections in our neighborhood:

A queue analysis was performed at the intersections of Holly Street with Industrial Road and Old County Road. At the intersection of Holly Street and Industrial Road, the queue leaving town during the AM peak hour would be about 640 feet, assuming a vehicle length of 20 feet. This is about 1/3 of the distance between Industrial Road and Old County Road.

At the intersection of Holly Street and Old County Road, the longest queue would occur during the PM peak in the westbound direction. Holly Street
consists of a one-lane roadway that transitions into two 420 feet long lanes approaching Old County Road. The queue on this approach would extend about 480 feet, which is just past the two lane section.

Potential Sub Area Impacts
The intersection of Holly Street and Old County Road, which is tied also to Holly Street and El Camino Real, was found to be the key intersection that could be adversely affected by new development. This intersection would most likely be the first to show an impact if development levels were to increase beyond the baseline size. It was calculated that at the intersection of Old County Road and Holly Street, roughly 100 additional peak hour trips
could be added to the critical movements beyond baseline levels before it would begin to operate at an unacceptable level of service, LOS E.   City staff identified 8 areas of the city to test for potential impacts. The areas are the following:

Industrial Road (HIA) – from Belmont Creek (just south of Harbor Boulevard) to 405
Industrial (just north of Holly Street)
Industrial Road (central) – from Holly Street to Brittan Avenue
Industrial Road (south) – from Brittan Avenue to Cordilleras Creek
El Camino Real (north) – from Belmont city limits to Arroyo Avenue
El Camino Real (south) – from Arroyo Avenue to Redwood City limits
Laurel Street (downtown) – from Holly Street to Arroyo Avenue
Laurel Street (central) – from Arroyo Avenue to Belmont Avenue
Laurel Street (south) – from Belmont Avenue to Eaton Avenue

The sub areas were analyzed with 100,000 square-feet (s.f.) of office development in order  to see the effect of each of these areas on the key intersection. The Laurel Street (downtown) sub area was the area that would have the greatest impact at the key  intersection. Only about 220,000 s.f. of office use could be built without going over the  100 trips threshold.

There are some good design examples in the link below.  We should encourage the city council to examine these in detail and use them as a design blueprint for new development in the city.
