SUBJECT: PRE 95-21 - FALCON HILLS
APN: 167-112-07
Preliminary review of your project was conducted on June 29 and July 6, 1995. Listed below
are the issues raised by staff. Please note that the purpose of a preliminary review is to provide
you with direction and comments on the overall concept of your project. The preliminary
review does not represent an in-depth analysis of your project. Additional issues of concern
may be raised after your application is submitted and processed for a more specific and
detailed review.
Planning:
1. The plans submitted were very general and conceptual in nature and typically would not
have sufficed for a standard preliminary review. However, the applicant's stated purpose
for the preliminary review was specifically to have staff comment not on the plans, but
rather on the concept of lowering the pads via double and triple split level terraces while
at the same time increasing the pad area outward through the corresponding lowering of
the pads and slopes. Therefore, given the agreed to conceptual nature of the review,
nothing in this letter is intended to be a firm staff comment regarding architecture,
landscaping, setbacks, grading quantities, or compliance with applicable development
standards.
2. Staff feels that the existing pads in the subject Falcon Hills subdivision are sufficient in
size to accommodate a reasonable house while complying with applicable development
standards. Scaling out the footprints shown on the submitted preliminary exhibit, homes
ranging upwards of 3,000 square feet are depicted. While these structures would have
to be trimmed to fit on existing pads, they still appear to accommodate good sized
residences. The CC&R's of Falcon Hills are apparently more restrictive than City
limitations regarding height and therefore represent a constraint beyond the City's control
or influence. In addition, the City's Zoning Ordinance prohibits encroachments into/onto
slope greater than 40%. However, the basic concept of lowering/terracing the pad areas
and increasing/extending the pad areas is supportable by staff on a conceptual level
(consistent with staffs allowance for very minor encroachments for single family
scenarios) with certain limitations as outlined below:

* Only minimum disturbance will be allowed to the existing pads and adjacent slope
area. This means wall/retaining wall heights must be 3 feet or less in order to
consider any modifications to the existing site.
* All pertinent aspects of the Hillside Development Ordinance must be complied
with including grading quantities, slope heights, etc.
* A formal amendment to the existing Hillside Development Permit would be
required to gain approval of the proposed grading concept/modification.
* A 10 foot minimum structural setback from the top of slope (future or existing)
must be provided with the future placement of homes.
* Grading and building permits will likely be required.
* Adequate screening of walls/revised landscape concept and plans will likely be
required.
3. It is anticipated by staff that your proposed concept will be more fully developed in
conjunction with specific floor plans/architectural product types and that a second
preliminary review will take place with staff prior to submitting the HDP amendment
package. In this manner, staffs level of support can be gauged again during the evolution
of the proposed concept.
Engineering:
1. Lowering the pads and having a structure that steps down the hill would be desirable
from Engineering's point of view except for the drainage issue as noted below.
2. Changing an existing grading scheme that has standard drainage to the street to one that
requires this drainage to be directed to adjacent property should be undertaken only with
a careful examination and full knowledge of the difficulties involved. The difficulties we
see and some related comments follow:
a. Although the property before grading had a drainage pattern hi the general
direction proposed in this preliminary review, that is not the direction of the total
amount of drainage now. There would be a requirement to keep the drainage
amount no greater than the amount would be if the existing, as graded, pattern
remained.

b. In order to keep the amount of drainage equal to existing, a retention system
capable of reducing the 100-year frequency post development peak amount to the
existing peak amount would be needed.
c. Such retention facility as above would most likely need to be impervious to
percolation. That is, unless a thorough examination of the underlying soil
conditions and geological formations made by a qualified professional reveal that
such percolation would not be a problem.
d. There exists the possibility that this retention facility should be considered an
underground reservoir within a hillside area and that presents very stringent design
requirements.
e. Also the discharge would need to be controlled to obtain an acceptable flow
pattern.
f. There is a shallow canyon on the downstream adjacent property that will tend to
concentrate any drainage amount into a flow channel. The amount and velocities
of drainage and erosive properties of the soil will need to be evaluated.
g. Possibly the amount of drainage could be reduced by keeping the driveways and
front yards draining to the street with as much roof drainage as possible collected
and directed to the driveways. Only a detailed hydrology study would be able to
tell this, but the reduction may be able to make the above retention facility a more
practical size and design.
h. Alternatively to retention, the developer could obtain easements and build a
drainage facility to an approved drainage course. When a facility handles drainage
originating only on private property, the facility would necessarily be privately
maintained. Each lot contributing drainage would need to have the responsibility
for maintenance clearly identified.
i. Also alternatively to retention, the downstream property owners may be willing
to accept the drainage increase and acknowledge this in an acceptable form such
as granting the developer a drainage easement. Such an acceptance would need to
be reviewed to assure the City that the owners are fully aware of the developer's
specific proposal.
j. In either case, the developer-owner would have to assume full responsibility and
hold the City harmless for any amount of cross lot drainage. Unless such an
agreement has already been recorded a Hold Harmless Agreement for Drainage
would be recorded on any lot causing cross lot drainage.

re: Falcon Hills
Please find attached a preliminary review application for the noted project. Our intent in making this application
is to determine the feasibility of building split level, single family homes on the existing parcels. We have
developed preliminary designs using that concept and believe that they are feasible. Our purpose in submitting
this application to discover if such a concept will be in conformance with City ordinances and the conditions of
approval for this project.
If you have any questions or need more information, please do not hesitate to call me at 943-1915.
Thank you for your attention to this matter.

PRE 95-21 FALCON HILLS SUBDIVISION
At a regular engineering staff meeting today, the preliminary review was discussed. The submitted plan itself
is not considered suitable for a preliminary review. However we did review the concept of lowering pads and
draining to the back of the lots.
1. Lowering the pads and having a structure that steps down the hill would be desirable from
engineering's point of view except for the drainage issue, below.
2. Changing an existing grading scheme that has standard drainage to the street to one that requires
this drainage to be directed to adjacent property should be undertaken only with a careful
examination and full knowledge of the difficulties involved. The difficulties we see and some related
comments follow:
a. Although the property before grading had a drainage pattern in the general direction
proposed in this preliminary review, that is not the direction of the total amount of drainage

would be if the existing, as graded, pattern remained.

reducing the 100-year frequency post development peak amount to the existing peak amount
would be needed.
c. Such retention facility as above would most likely need to be impervious to percolation. That
is, unless a thorough examination of the underlying soil conditions and geological formations

LIST OF ITEMS NEEDED
TO COMPLETE APPLICATION:
No. HDP 89-18
PLANNING:
1. Assurance of accurate hillside mapping is required pursuant to Section
21.95.020(c) of the Zoning Ordinance. Both the slope analysis and slope
profiles are required to be stamped and signed by either a registered
landscape architect, civil engineer, or land surveyor.
2. Indicate the datum and source of topographic data used in the slope
analysis and slope profiles.
3. Provide contour information for the driveway and indicate the proposed
slope percentage. Consult engineering standards for permitted maximum
slope.
ENGINEERING:
1. Existing slope at Cazadero Drive is too steep. Will require filling to
2:1 or installation of retaining wall.
2. Setbacks from property line are insufficient.
3. Cross lot drainage will not be allowed.
4. Title report is too old.
ISSUES OF CONCERN
PLANNING:
1. Volume of fill and area of grading. The site design should utilize a
development approach requiring a minimal amount of grading consistent with
the intent of the Hillside Development Regulations. One alternative is
to build into the existing slope of the site and limit the area to be
graded as has been accomplished on neighboring properties. The applicant
should consult the Hillside Development Guidelines.
2. Vertical nature of proposed crib retaining wall slope. Graded slopes
should not exceed 2:1. Crib walls should not be used as proposed adjacent
to the existing sewer easement because of their vertical nature which does
not blend in with the existing topography.
3. Screening of graded slopes. Graded slopes should be obscured from view
by utilizing landscaping screens such as trees downslope in addition to
placing a berm or small block wall along the top of the north facing slope.
