Authorize the Mayor to sign and send a letter to the Liberty Union High
School District regarding traffic issues at Heritage High School.
The City of Brentwood has completed various traffic-related projects in the
vicinity of Heritage High School and Adams Middle School. As a result,
school-related traffic congestion has improved. The City Police Department
and Engineering Division evaluated the flow of traffic in the area after the
City’s projects were completed and recommend some additional actions be
taken by the Liberty Union High School District to improve internal
circulation at Heritage High School.
The attached letter has been prepared to update the Liberty Union High
School District as to the improvements constructed thus far and provides
recommendations for additional future improvements.

Dear Ms. Hartman and Board of Trustees:
The City of Brentwood appreciates the challenges and efforts of both the
Liberty Union High School District and Brentwood Union School District in
constructing new school campuses. Together we have provided outstanding
facilities, both educational and recreational, for our residents. One of our
remaining challenges is the traffic congestion on American Avenue.
Since the opening of Heritage High School in 2005 and Adams Middle School in
2006, the City has completed the following projects to alleviate traffic
congestion on Balfour Road and American Avenue:
1) A second left turn pocket was added on westbound Balfour Road at American
2) A second right turn lane was added on American Avenue at Balfour Road.
3) The traffic signal was modified at Balfour Road and American Avenue to
allow additional vehicles to turn right onto Balfour Road.
4) The crosswalk on the east side on Balfour Road was removed to increase
the time available for vehicles to turn right onto Balfour Road.
5) Two sets of stop signs were removed along American Avenue to expedite
vehicles leaving Adams Middle School.
The City and Brentwood Union School District jointly funded the addition of
a second lane at the southern end of American Avenue to provide two lanes
for vehicles leaving Adams Middle School.
In addition, the City has provided police services during peak times.
While these projects have been successful in improving capacity on Balfour
Road and American Avenue, the City’s Police Department and Engineering
Division believe traffic circulation on the Heritage High School campus is
continuing to cause congestion on American Avenue and Balfour Road.
The City’s Police Department and Engineering Division assessed the situation
and recommend the following actions to improve internal circulation:
1) Place a crossing guard at the main parking lot entrance to move right
turning vehicles into the parking lot while controlling pedestrian
2) Allow multiple lanes of traffic in the student parking lot, instead of
one, to facilitate drop off and pickup traffic;
3) Add a secondary exit off of the student parking lot onto Balfour Road;
4) Allow student drop off in front of the rotunda; and
5) Relocate the staff parking area to enhance circulation in the student
The City Council recognizes that the internal circulation of traffic on the
campus is within the District’s purview, and not the City’s. We respectfully
request that the District work with its traffic consultants and strongly
consider our recommendations to resolve these internal circulation problems.
We thank you for addressing this matter expeditiously.
Mayor, City of Brentwood
