CHULA VISTA CITY COUNCIL MEETING OF: February 5, 1974
ITEM TITLE: Resolution.. Approving tentative map of Bonita Ridge Estates
Subdivision PCS~73~6
INITIATED RY: Director of Planning
A. BACKGROUND
r:-TIieffinning Commission first considered this. subdivision map on December 12, '1973.
After hearing extensive testimony from the staff, applicant, and residents living
adjacent to the area, the Commission continued the matter to January 23, 1974 to
enable the staff and applicant to redesign the subdivision map to improve the circula~
tion system. .
2. Tb~ revised te..ntative map, a copy of which is enclosed, was considered by the
Planning Commission to adequately improve the circulation pattern by deleting one
of the two street connections to Acacia Avenue.
3. (IR~73~17 was adopted by the Planning Commission on December 12, 1973 for the
original tentative map. After the revised map was submitted the Environmental Review
, Committee determined on January 10, 1974 that the changes proposed waul d not require
a new E. I.R. '

B. ANALYSIS
1. General Information.
This development, which proposes 136 lots on 107 acres, is located in the northern
portion of the same ri dge as Ranchito Robi nhood, the tentative map approved by the
Ci ty .Counci 1 on November 27, 1973. The.re are three phases of development, starting
with the land adJacent to Bonita Bel Aire subdivision and Otay Lakes Road. The lot.
sizes have been reduced from 20,000 sq. ft. minimums to an average of 10,600 sq. ft.
. to pennit the developer to minimize the grading of the 107 acres (approxtrnately 50%
of the site is being left in its natural state}. The "H" District provistons were

were not used for comparison on this project since the R~E zone category was deleted
from the nomograph. However, if the property were zoned R~l~H approximately 110
dwelling units would be allowed. The development conforms to the intent and spirit
of the "H" District Pol icy by: (l) minimizing grading, (2} reducing the density
considerably below what would be expected under a mass grading plan with 20,000 sq.ft.
lots, (3) using various design features, such as panhandle and sp1it~leve1 lots, to
better fit the development into the existing topography.
2. Circulation.
The majority of the streets are to be public and have 51 feet of right of way with
24 to 36 feet of pavement. Otay Lakes Road is being widened to one..ha 1 f of its
ultimate width. Private drives have been provided ranging from 12 feet for individual
homes to 24 feet for groups of homes. T~type turn arounds have been provided in
various areas which pose difficult problems for larger vehicles, such as fire equip~
mente The major street system along the ridge top connects to Camino E1evado to the
north and to the Ranchito Robinhood street to the south.
One cu1 de sac in Unit #2 gains its access via a connection to Acacia through an
existing parcel. Access to Unit #3 is dependent upon development of Ranchito Robin~
hood.
3. Drainage.
a. On Site.
The Director of Public Works retains full review and approval authority over
all drainage improvements on the property. Detailed drainage plans are reviewed
after the tentative map is approved, but before the final map and improvement plans
are approved.
b. Off Site.
The Director of Public Works has determined that development of this subdivision
will create an insignificant increase in runoff. The attached memoranda, one from
the Director of Public Works dated January 16, 1974 and the other from the County
Department of Sanitation and Flood Control dated January 9, 1974, discuss the method
by which the off-site drainage facilities can be improved between this development
and Bonita Road. That method involves the fonnation of a "Specia1 Drainage Area"
(S.D.A.) among the property owners involved. This action was apparently acceptable
to the spokesman for the affected property owners, Mr. Robert Walton, 4030 Acacia;
however, neither the City nor the County has to date received a written request to
have the S.D.A. action initiated.
4. Site Design.
a. Over one-half (83) of the 136 lots are proposed for split level houses,
taking advantage of the views or reducing the size of the manufactured slopes between
lots. Some of the lots have panorama views and the units will be oriented to take
advantage of these views.
b. 35 of the lots are either panhandle lots or are served by the private common
driveway, thereby implementing one of the major design features of the Hillside
Development Policy.
c. Varying setbacks are proposed along the streets. The drawings which have
been submitted to the City show an average front yard setback of 25 feet which con-
forms to the R-E zone provision.
d. Significant stands of existing vegetation will be retained.
5. Open Space Maintenance District.
The applicant proposes to petition the City to form an Open Space Maintenance
District comprised of lots 137 through 144. The District will include an equestrian
trail s system.

6. Landscaping.
All manufactured slopes will require landscaping and irrigation; the natural ungraded
areas will also require supplemental landscaping and associated irrigation similar
to that proposed for Ranchito Robinhood. All such landscaping and irrigation will
be subject to review and approval by City staff.
7. Relationship to homes on Acacia Avenue.
Some of the homes of this project will overlook the Acacia Avenue development,
particularly those lots in Unit 2. This development, however, is separated from
Acacia horizontally by a major drainage area. The closest point of approach of the
lots of this development to those on Acacia is 60 feet to the lots and 100 feet
to the houses. Significant slopes have been created in Unit 2 to provide the pads.
The elevation differences in Unit 2 of this development range from 198 feet to 237
feet. The elevations of the homes on Acacia range from 170 to 190 feet.
The significance of the slope is minimized by three factors: (a) The natural
slope in this area is approximately 3:1 (3' horizontally to 11 vertica11yl compared
to the proposed 2:1. (b) The slope extends across the rear of four lots and then
blends into the natural slope. (c) Landscaping will be required for aesthetic
beauty as well as erosion control.
8. Sewer.
Sewer will be built along the course of the drainage area to serve the Bonita Ridge
project. This sewer line will be physically accessible to Acacia homes where there
has been a history of septic tank problems. However, in order to obtain a sewer hook
up a house would have to be in the City Limits of Chu1a Vista or a recognized sewer
district.
9. Equestrian Trail System.
The applicant has indicated his willingness to provide access for equestrian trails
across the property. The location of these trails is shown schematically on the
tentative map enclosed in the packets. Details of the trails, including grading
and dimensions, will be included in the landscaping, irrigation and improvement plans.
10. Environmental Impact Report.
The EIR identifies two impacts for which mitigating measures will be needed as
follows:
a. Lots 1-6 will have a normally unacceptable noise level at the second story
level during peak hour traffic conditions.
b. Downstream offsite drainage facilities are inadequate for even today's
runoff. The accumulative effect of future development of Long Canyon drainage
basin will cause a significant drainage problem unless these facilities are
improved.
11. There is an existing pump station located adjacent to "A" Street presently
operated by California American Water Company. Because of its close proximity to
the road, special architectural treatment should be considered to house the facility.
12. Proposed land swap.
At the point where proposed street "D" crosses over from Ranchito Robinhood into
this project, there is proposed to be a mutual land swap which will facilitate the
site design of proposed lots. This land swap will be executed by an agreement between
owners, a copy of which will be furnished to the City. In addition the tentative maps
of both projects will be revised to show the new boundaries.
13. Architecture.
Site plan and architectural review of house plans for each lot will be submitted to
the City staff. The developer has indicated units will be in the $50,000 to $70,000
price range, containing in excess of 2,000 sq. ft. with wood shake roofs. ;( 71/Pf
