PROJECT DESCRIPTION AND ENV2ROMIUTTAL SETTING
This project involves adoption and implementation of a master plan
of storm drainafacilities fora 375 -acre area in tL.e northwes'L
Chico vicinity. The study area is bounded by Esplanade ;on the eas,-
Westt 6th Avenue on the south; the Southern,-Pacifa_c Railroad Vi8ht
of -way on. the west and Lando Cannel on the north. The area is
primarily outside of the corporate limits of the Ci 4 of Chino -,
v', it contiguous on the south to the city limit linea
howe8th Avenue and a portion of. West 11th Avenue have been Mi
nexed into the city. In. addition, a few parcels wLbhin the area
have also -beenL annexed: Following adoption of. the master clan,
=i
draag.e facilities will be installed in phases as requI I to
serve land development Projects in the` area.
Facilities to be installed consist of a basic collector system for
storm drainage 'which is 'an imter•-connected system of underground:
pipes Varying in diameter from P-1 ;inches to, 84 inches to,4alling
16,730 lineal feet if they, v,-oxe laid end to end. These pips , will
be,iinstalled primarily wAh;.,n the right s- of -1,;ay of el.,ci8t ng streets
Which presently serve the area and proposed streets which will, be.
built to serve future development projects. The outlet for the
systemic Located at the extreme west boundary, of the project area
and. consists of an outfall lame which parallels the east boundary

The project area is ess`entidll-y level, sloping slightly (apPro.,-i._

approved over the past sit years; it is anticipated that the ares".
will be fully developed within the next ten to fifteen years The
Butte County General Plan designates. the area medium= -low density'
residential; 5-$ dwelling per gross acre. The current zoning is

East Chico Drainage study, - the area is located adjacent to and
to the east of Chico Canyon Road, bordered on the west by
Forest Ave., on the south by Highway 32 and a portion of
Humbolt Road; and on the east by an extension of Chico CanyonRoad. This area is between the east bank of Big Chico Greek
and the north bank of Little Chico Creek.
The terrain ranges..
from very flat in the western portion to a gentle slope in the
eastern portion.
At present this area Is being developed for
residential use,_which is ;replacing the scattered small

PROJkT DESCRIPTION AND.ENVIRONMENTAL SETTING
This Project involves adoption and implementation of a master plan
of storm drainage facilities for a 420 -acre area in East Chico,
The study area is bounded by Forest Avenue on the west, Calif
Park Subdivision, and Centennial Avenue oil the a
east, Bz g ,Cha Creek
Chico arji
an the north, and Humboldt Road and State Highway 32• on the south.
Following adoption of the master lan, drainage faeilities will be
installed in` phases as required to' service la'' r�oeloprnent projectswithin the area, n
in _
Facilities to be installed consist of eight separate N 4nelines vary-
ing in diameter .from 33 -inches to 54 -inches and in 1en�srh from x'00
feet to 2000 feet, r4ive of the proposed trunk lines will drain onto

The Project' area consists mainly of rolling grassland which has been
divided into a var;,ety Of Parcel sizes ranging from small subdivision
lots (Shirley Park Subdivision, El, Monte Heights Subdivision, Cen:,
tennial Estates Subdivision) to a few large parcels of almost QO''
acres. There are scattered residences throughout the axes std some
