PROJECT REPORT
PROJECT ID: CT 93-08/PUD 93-07 PREPARED BY: Kenneth Quon
PROJECT NAME: RANCHO CARRILLO, VILLAGE '0' APPROVED BY: / :('/f
LOCATION: West of Melrose Avenue, south and east of Carrillo Way, in the Rancho Carrillo
Master Plan area.
BRIEF DESCRIPTION: A tentative map and planned unit development consisting of 51 single family
homes on 52 lots.
ENGINEERING ISSUES AND DISCUSSION
TRAFFIC AND CIRCULATION
Projected Average Daily Traffic (ADT): 10ADT/unit x 51 units = 510 ADT
Traffic Study Performed by: Darnell and Associates, Inc.
The circulation system for Village '0' has been laid out in accordance with the requirements of the
previously approved Rancho Carrillo Master Plan.
The road system consists of local through streets and local cul-de-sac streets, all of which are public.
These streets have been designed to City standards and will consist of a curb-to-curb paved width of
either 40' or 36', curb, gutter and a 5' wide utility easement on each side. Sidewalk will be provided
on one side only for single loaded streets, and provided on both sides for double loaded streets.
Access to Village '0' will be through a short 40' wide street that connects the project to Carrillo Way.
A second street intersection with Carrillo Way at the south end of the project will serve as an
additional access point.
This project also includes a portion of the Rancho Carrillo Master Plan Trail system. This trail will be
located at the northern end of the development and will terminate at the intersection of Carrillo Way
and Melrose Drive.
The stretch of Carrillo Way from the entrance of Village 'Q' to the southern boundary of Village '0'
has also been proposed as part of this tentative map. This portion of roadway will be constructed with
full width street improvements.
The Rancho Carrillo Master Plan identifies several planned streets to be included in the adjacent Village
'Q' that will also serve as access to Village '0'. It is also likely that the planned street improvements
for Village 'Q' will be constructed prior to the development of this project. However, as a "stand
alone" project, this tentative map requires the identification of a second access point outside of the
proposed access on Carrillo Way via Melrose Drive. A condition will be placed on this project to
identify and delineate a second access point on the conformed tentative map exhibit.
As circulation improvements have yet to be constructed for the entire Master Plan area, a condition
of this project will specify that the construction of Melrose Drive, Poinsettia Lane, and El Fuerte Street
be guaranteed prior to approval of the final map, and substantially completed prior to occupancy of the
first unit.
SEWER
Sewer District: Carlsbad Municipal Water District
Sewer EDU's Required: 1 EDU/unit x 51 units = 51 EDU's
Sewer service to Village '0' will be provided by a public sewer line that will tie into a 12" sewer main
to be installed for the entire Rancho Carrillo development. The sewer line for this project will drain by
gravity flow in a westerly direction and through the northern portion of Village 'Q', where it will join
the 12" sewer main. This sewer main will connect with an offsite pump station, which will pump
sewage to the existing Buena/San Marcos Interceptor system presently located on El Camino Real.
As sewer improvements have yet to be installed for the entire Master Plan area, a condition of this
project will specify that an alignment for the sewer be established, an environmental review be
completed, and a financing mechanism guaranteeing construction of the sewer facilities be provided
prior to approval of any final map.
WATER
Water District: Carlsbad Municipal Water District
EDU's Required: 220 GPD/EDU x 51 EDU's = 11,220GPD
Domestic water will be provided to Village '0' from a trunk line of the 12" water main on Melrose
Avenue. The trunk line will enter the development through a 15' wide easement located at the
northern end of the project. The 12" water main will be installed concurrently with the construction
of Melrose Avenue.
An 8" reclaimed water line will also be installed on Melrose Avenue, and will be tapped for irrigation
of the slope areas in Village '0'.
As water improvements have yet to be installed for the entire Master Plan area, a condition of this
project will specify that water line improvements be guaranteed prior to approval of the final map.
GRADING
Quantities: Cut: 102,600 cy Fill: 428,300 cy Export: 325,700 cy
Permit Required: YES
Offsite Approval required NO
Hillside Grading Requirements met: YES
Preliminary Geotechnical Investigation Performed by: Geocon, Inc.
Development of the Rancho Carrillo project includes plans for a comprehensive 7-phase grading
operation. Phase 1 will complete a majority of the grading required within the entire Master Plan. This
mass grading effort will include grading of the circulation element roads, partial grading of several
village areas, remedial work to correct underlying geotechnical issues, and mitigation areas required
by road impacts on sensitive biological areas.
The remaining phases will be limited to site specific grading of the residential village areas, such as
Village '0'. For this project, the grading quantities (in cubic yards) identified above will be performed
in the following phases:
Cut Fill Import
Mass grading (Phase 1) 100,700 418,500 317,800
Site specific grading 1,900 9,800 7,900
TOTAL 102,600 428,300 325,700
The geotechnical report for Village '0' states that no soil or geologic conditions were observed or noted
that would preclude the development of this project, provided the recommendations of the report are
followed. The report did cite that two medium size landslides and a number of smaller slides have been
mapped along the eastern portion of the Village '0' property. However, in general, these landslides
are ancient landslides that have likely been dormant for some time, and can be stabilized by following
the recommended operations detailed in the report.
DRAINAGE AND EROSION CONTROL
Drainage Basin: San Marcos Creek Watershed
Preliminary Hydrology Study Performed by: Rick Engineering
Erosion Potential: Low
Surface drainage will be conveyed by standard curb and gutter that drains to an underground storm
drain system. The underground storm drain system will discharge into a check dam system to be
located on the opposite side of Carrillo Way. In turn, this check dam system will connect to the major
drainage outlet planned for the Rancho Carrillo development.
As drainage improvements have yet to be installed for the entire Master Plan area, a condition of this
project will specify that construction of drainage improvements be guaranteed prior to approval of the
final map.
LAND TITLE
Conflicts with existing easement: NO
Easements dedication required: YES
Site boundary coincides with Land Title: YES
Easements to be dedicated include a 15' wide public easement for water service, a 15' wide public
easement for sewer, a 15' wide public easement to convey drainage from the slope areas, and a public
drainage and access easement. The slope area facing Carrillo Way will be dedicated as a public open
space easement to the City.
IMPROVEMENTS
Off site improvements: YES
Standard Variance Required: NO
Project improvements will consist of major sewer, water, drainage, and roadway facilities.
Construction of these improvements will be in accordance with the Rancho Carrillo Master Plan and
with the Conditions of Approval for the project. Project development cannot occur until such time as
all major infrastructure is provided.
