III. Reasons for Recommendations and Background: (Continued)
The proposed location of the 14-inch line is in close proximity to a proposed Flood Control
District 30-inch diameter drainage line (Line A). The proposed 30 inch line is designed to serve
as an outfall line from four detention basins to Marsh Creek, in Drainage Area 52C.
In order to avoid the extra expense and disruption that separate construction of the 14-inch and
30-inch lines would entail, the City of Brentwood and the Flood Control District desire to install
Line A as a part of the City's expansion project. The purpose of this agreement is to provide
for the apportionment of project duties and costs between the City and Flood Control District.
