314-2015 LETTER TO COMMISSION
TO: Mayor Philip Levine and Membe of the Cit Commission
FROM: Jimmy Morales, City Manager
DATE: August 5, 2015
SUBJECT: LOWER NORTH BAY ROAD STORM DRAINAGE SYSTEM CONSTRUCTION
BETWEEN NORTH 20" STREET AND THE INTERSECTION OF ALTON ROAD AND
CHASE AVENUE, INCLUDING THE SIDE STREETS.
The purpose of this Letter to Commission is to provide a construction update on the Lower North
Bay Road (LNBR) Project and information regarding the commencement of the new Stormwater
Drainage System installation.
Lining of the sanitary sewers is complete. Water main installation is over 60% complete and will
continue for another 2-3 months.
The new drainage system comprising of 18 to 42-inch pipes and structures will be installed along
Lower North Bay Road from North Michigan Avenue to the intersection of Alton Road/Chase Avenue
as well as the intersecting streets.A pump station and its related components will be installed at the
West 23rd Street end. Please be advised that installation of this infrastructure will require heavy
construction machinery and temporary road closures.
During the week of August 10, 2015,the contractor will commence the drainage system installation
at the intersection of West 23rd Street and progress north toward West 29th Street. Due to the
nature of the installation and the location of the large drainage structures and 42-inch drainage
pipes(along the center of the roadway)portions of the roadway will be rendered impassable in the
immediate vicinity of the installation, except to local traffic and emergency vehicles. Access will be
coordinated and maintained to properties at all times. Maintenance of Traffic (MOT) will be
appropriately placed. Flagmen will ensure impact to local traffic flow is minimized and will direct
motorists to alternate routes. As the work progresses, weekly construction updates will be sent to
the residents, including the Sunset Islands HOAs.
Following the installation of the drainage system the street will remain unpaved for a period of time
before the contractor begins the road reconstruction process. This process involves removal of
unsuitable soils, preparation of the road sub-base, placement of limerock base, installation of valley
gutters and finally placement of the of asphalt. Construction of the drainage system will take 5-6
months. Road reconstruction should start in 2-3 months.
