Staff Report to the Planning Commission
RE: CONDITIONAL EXCEPTION TO ROAD DESIGN STANDARDS FOR MAXIMUM
CUT AND FILL ALLOWED; LANDS OF HORTON; CHAPARRAL WAY
SUBDIVISION; FILE# 77-04-MISC.
FROM: _ Angelica Herrera Olivera, Assistant Planner
APPROVED BY: Carl Cahill, Planning Director
RECOMMENDATION That the Planning Commission:
1. Recommend for City Council approval the proposed roadway retaining wall design and
conditional exception, which includes approximately 15 feet of cut and 9 feet of fill,
subject to the attached conditions of approval and findings.
BACKGROUND
The City Council approved a Tentative Map for a four -lot subdivision on Chaparral Way on July
18, 2002, subject to conditions in Attachment 3. A 20 -foot wide road, within the existing 40 -
wide Chaparral Way right-of-way, provides access to the site from Moody Road. The proposed
entry cul-de-sac off of Chaparral Way contains a 24 -foot roadway within a 60 -foot private
easement, which provides direct access to Lot 1. A 35 -foot wide private easement provides
access to Lots 2, 3 and 4 off the western side of the cul-de-sac.
The steep terrain along the roadways leading from Moody to the end of the cul-de-sac, along with
required drainage facilities along and above the retraining walls necessitate taller retaining walls
than the originally proposed 4 -foot tall retaining walls on the preliminary grading plan for the
Tentative Map.
The applicant is requesting a conditional exception to the road design standards for the Town,
which limits the maximum cut and fill to 10 feet and 8 feet respectively. The proposed roadway
retaining wall design requires up to 15 feet of cut and 9 feet of fill. However, the actual heights
of the proposed roadway retaining walls vary from 4 feet to 101/2 feet tall.
Pursuant to Section 9-1.703 of the Subdivisions Ordinance, a 10 -foot maximum cut and 8 -foot
maximum fill is permitted in designing public and private roads.
Pursuant to Section 9-1.1501 of the Subdivisions Ordinance, the Planning Commission may
recommend for Council approval conditional exceptions from the provisions of this chapter
when, in the opinion of the Planning Commission, undue hardship may result from the strict
compliance with the provisions of this chapter, and an exception would not be contrary to the
public interest. A recommendation for Council approval of a conditional exception requires that
the Planning Commission approve certain findings. Staff has prepared the necessary findings for
the Commission's review in Attachment 2.

Roadway Retaining Wall Design
The color -coded Sheet 1 of the Retaining Wall Site Plan illustrates the range in retaining wall
heights proposed for the required roadways leading from Moody Road and Chaparral Way. The
areas where the proposed cut and fill exceeds the maximum allowed pursuant to the Subdivisions
Ordinance have also been labeled on Sheet 1. A majority of the retaining walls along the
proposed roadway will exceed 4 feet in height. Approximately 2,595 lineal feet of retaining wall
length will exceed 4 feet in height—approximately 64 percent of the total amount of retaining
walls. Staff is recommending in condition of approval #1 that the proposed retaining walls
shown along the driveway for Lot 1 (on west side of cul-de-sac), which include a 10'/z tall
retaining wall, be reviewed at the time of site development with a new residence.
Sheet S0.0 shows the typical retaining wall section along the roadway. The majority of the
proposed retaining walls are terraced, up to three walls, in order to reduce the overall height of
the retaining walls and to provide area for landscape screening. In addition, the walls are sloped
back at a six degree angle to provide a more natural looking appearance. Three different types of
roadway retaining walls were originally proposed: tie -back walls, pier and grade beam walls, and
geogrid walls. However, the Town Geologist voiced several concerns regarding the proposed
geogrid retaining walls, including a greater anticipated impact on existing trees. The current
proposal involves only tie -back walls and pier and grade beam walls.
Landscaping and Materials
The Initial Study for the 4 -lot subdivision indicated that a total of 36 oak trees would have to be
removed on the access road and Chaparral Way. An oak tree replacement plan is required as part
of the Tentative Map project as mitigation. Oak trees that need to be removed shall be replaced at a
1:1 ratio as part of a landscape replacement plan submitted to the Planning Department for approval prior
to recording the Final Map.
The applicant is proposing to mitigate the extensive length of retaining walls by using a stone-
like, earth tone colored, Allan -block veneer. Attachment 4 includes two separate views of the
proposed roadway retaining wall design. Staff is recommending in condition of approval #2 (see
Attachment 1) that the proposed color scheme for the Allan -block veneer be a darker hue of the
same colors to blend in with the proposed and existing vegetation. A recommendation is also
proposed for the color of the roadways and all proposed concrete surfaces to reduce the potential
visibility of the improvements from other surrounding hillside properties.
The proposed landscaping selection, size, and placement are shown on Sheets 1, 2 and 3.
Extensive landscaping is proposed both along the bottom as well as overhanging the tops of the
retaining walls. As stated on the plans, the plants have been selected for their native or
"naturalized" characteristics, drought and deer resistance, and compatibility with the weather and
soils of the region. All planting areas shall be irrigated with a fully automatic drip irrigation
system. Attachment 5 illustrates a colored version of Sheet 4 of the plans, which demonstrates
the view of the terraced retaining walls from Moody Road immediately after landscaping and a
view of the walls a few yeas later.

Geotechnical Review
The Town Geologist has reviewed the proposed roadway retaining wall design and has provided
conditions, which have been incorporated in Attachment 1. The main issues centered on the
structural feasibility of the proposed retaining wall design and the overall impacts to the site
regarding grading and vegetation removal.
Engineering Review
The Engineering Department reviewed the proposed roadway retaining wall design for the
maximum heights of cut and fill only. The final detailed grading and drainage plan for the street
improvements for the Tentative Map shall be submitted to the Town once the retaining wall
design has been approved.
Possible Alternatives
While alternatives to the proposed roadway design are possible, the net effect would be similar—
substantial oak tree removal and excessive grading. The overall steepness of the site limits the
possible alternate locations for the roadway. Situating the roadway further to the east would cut
further into the hillside, requiring taller retaining walls and the additional removal of vegetation.
Siting the roadway further to the west would create the same situation on the hillside east of the
natural drainage Swale.
The width of the roadway is another way in which the proposed roadway retaining wall design
could be altered. The July 18, 2003 conditions of approval for the 4 -lot subdivision require a 24 -
foot roadway. A lesser width could reduce the required cut and fill, retaining wall heights and
perhaps be cause for fewer oak trees to be removed. However, the steepness of the winding cul-
de-sac necessitates the 24 -foot width for fire truck access.
Findings for a Conditional Exception
In making its findings, the Planning Commission shall consider the existing land use of the area,
the nature of the proposed use of the land, and the probable effect on traffic conditions. The
nature of the proposed use of the land calls for a 4 -lot subdivision. Any worsening of the traffic
condition along Chaparral Way during the construction of the entry cul-de-sac will be mitigated
once the existing road is widened to a 20 -foot wide paved roadway.
The strict application of the provisions of this chapter would deprive the applicant of the
reasonable use of the subject property. There are special circumstances and conditions affecting
the property that seem to warrant a conditional exception: 1) The majority of the site has 40
percent slopes or greater; 2) There is a large drainage swale located in the center of the site which
drains to Chaparral Way and Moody Road, 3) One relatively small landslide deposit and two
debris slides are located west of the main drainage Swale; and 4) The hillside site includes
extensive oak woodland and grassland habitat.
By granting the conditional exception to the applicant, no other landowner shall be deprived of
the reasonable use of their individual land or subjected to undue burdens or hardships or be

deprived of any material use or enjoyment of their individual property. The aesthetic
improvements, retaining wall replacement and widening along Chaparral Way will enhance the
access for the property owner to the east of the entry cul-de-sac (Lands of Mak) as well as for the
property owners located further west along Chaparral Way.
SUMMARY
The proposed roadway retaining walls have been designed to be aesthetically pleasing and
natural looking through the use of earth tone colored stone and extensive landscaping. Based on
the findings discussed earlier, the steep terrain and natural conditions of the property provide
special circumstances that merit a Conditional Exception to the allowable cut and fill for the
design of the proposed roadways.
Staff is available to answer any questions that the Commission or the public may have.
Staff determined the project to be categorically exempt from CEQA pursuant to Article 11,
Section 15162, "Subsequent EIRs and Negative Declarations" which allows project revisions that
do not involve new significant environmental effects or a substantial increase in the severity of
previously identified significant effects.

SUBJECT: Supplemental Geotechnical Review
RE: Horton/Blue Oak Ridge Subdivision
Chaparral Way
At your request, we have completed a supplemental geotechnical review of permit
applications for the construction of a new roadway and associated retaining walls using:
• Retaining Wall Elevations, Sections and Details (Sheets S1.2, S2.1 and S3.5)
prepared by Adamo & Associates, dated July 23,2004;
• Blue Oak Ridge Subdivision- Roadway retaining walls (8 sheets) prepared by
Adamos & associates, dated July 14,2004; and
• Retaining Wall Structural Calculations prepared by Adamo & Associates,
dated July 14, 2004.
In addition, we have reviewed pertinent technical documents from the proposed
project subdivision file.
DISCUSSION
We understand that the applicant is seeking Town approval of plans for the
construction of a roadway, and associated retaining walls into the subject property. In
our previous project review memorandum (dated July 1, 2004), we relayed a discussion
regarding project retaining wall design issues with Tom Adamo (Project Structural
Engineer), who had assisted in preparation of earlier project roadway wall design plans.
Mr. Adamo indicated that the originally designed geogrid reinforced retaining walls
along the roadway alignment would be replaced with tieback walls and/or pier and
grade beam walls. We understand that the basic appearance of these replacement walls
will be the same as the other tie -back walls and pier and grade beam walls previously

proposed for use along the roadway. The referenced revised roadway retaining wall
plans illustrated the design and proposed distribution of the above two types of walls.
Based on our review of the referenced documents, the revised roadway plans
resolve our previously indicated geotechnical concerns with project retaining wall
design. Consequently, we do not have remaining concerns with geotechnical aspects of
proposed project design.
We did note one apparent drafting error in the table on Plan Sheet SI.2 where the
values provided for 125 percent and 150 percent test loads are reversed. It would be
helpful if an additional column was added to this table indicating design load values for
each of the various sizes of wall tieback bars. We have presented these comment to the
Project Structural Engineer.
Prior to issuance of permits allowing initiation of roadway construction, we
recommend that the following Condition 1 be satisfactorily addressed.
1. Geotechnical Plan Review - The applicants geotechnical
consultant should review and approve, all geotechnical aspects of
the project building and grading plans and supporting wall
design calculations (i.e., site preparation and grading, site
drainage improvements and design parameters for retaining walls
and pavement to ensure that their recommendations have been
properly incorporated.
The results of the plan review should be summarized be the
geotechnical consultant in a letter and submitted to the Town
Engineer for review prior to issuance of building permits.
2. Geotechnical Field Inspection- the geotechnical consultant
should inspect, test (as needed), and approve all geotechnical
aspect of the project construction. The inspections should include,
but not necessarily be limited to: site preparation and grading, site
surface and subsurface drainage improvements, and excavations
for foundations and retaining walls prior to the placement of steel
and concrete. The consultant should also inspect the testing of
wall tiebacks.
The results of these inspections and the as -built conditions of the
project shall be described be the geotechnical consultant in a letter

This review has been performed to provide technical advice to assist the Town
with discretionary permit decisions. Our services have been limited to review of the
documents previously identified, and a visual review of the property. Our opinions and
