The export of cut material may be required to preserve the natural
topography of the project site. Cut material may only be exported
to an appropriate landfill or a site permitted to accept material.
|
For an addition to an existing structure, the height shall be
measured from the bottom of the first floor diaphragm on the ocean
side, or the lowest recommended finish floor elevation, whichever
is lower, and the center line of the road on the land side.
|
The Increase in Land Value Model - The economic value of the
public benefits and amenities offered by the applicant should be at
least 50% of the Increase in Land Value attributable to the additional
square footage, determined as follows: The lot area needed to build
the proposed square footage is determined, using 15% F.A.R. ("needed
lot area"). The actual area of the applicant's property is subtracted
from the needed lot area (the result is the "imputed additional lot
area"). The fair market value of the applicant's property is determined,
without considering the additional square footage, and converted to
a per square foot figure. The land value is multiplied by the imputed
additional lot area. The result is the Increase in Land Value.
|
The Avoided Cost of Development Model - The economic value of
the public benefits and amenities offered by the applicant should
be at least 50% of the Avoided Site Improvement Costs, determined
as follows: The lot area needed to build the proposed square footage
is determined, using 15% F.A.R. ("needed lot area"). The actual area
of the applicant's property is subtracted from the needed lot area
(the result is the "imputed additional lot area"). The cost to prepare
the imputed additional lot area is calculated, including such items
as grading, drainage, ingress/egress/circulation, parking, landscaping,
on site utilities, design and construction management costs (but not
the costs of the buildings). This sum is the applicant's Avoided Site
Improvement Costs.
|
The Increase in Total Project Value Model - The economic value
of the public benefits and amenities offered by the applicant, calculated
over the life of those benefits and amenities, should be at least
50% of the Increase in Total Project Value, determined as follows:
The City will engage a consultant to calculate the increase in Total
Project Value over the life of the project attributable to the additional
square footage, which calculation shall consider the following factors:
|
Annual Rent is per square foot (this would vary
based on the type of project).
|
Average occupancy over the life of the project.
Cost to Build/Sq. Ft. This is the cost for the building only (this
would vary based on the type of project).
|
Total Cost is cost per square foot (x) total square
footage.
|
Annual Debt Payment @ current rate % for 30 years
(this assumes 100% bank financing).
|
Taxes (assumes a property tax rate, including bonds
and assessments).
|
Insurance (assumes an all risk policy in the Malibu
area based on the size of the building).
|
Utilities and maintenance (assume a cost per square
foot per year respectively).
|
Depreciation (assumes a 35 year schedule for the
Total Cost of the building).
|
Income Taxes, based on the current state and federal
corporate rates (the federal rate is progressive and could change
depending on the amount of net income before taxes, the state rate
is proportional, not progressive).
|
Net Income After Taxes is the net profit to the
landowner.
|
Total Net Profit after taxes over economic life
is the net profit times 35 years.

If the bluff exhibits a factor of safety of less than 1.5 for
either gross or surficial landsliding, then the location on the bluff
top at which a 1.5 factor of safety exists shall be determined. Development
shall be set back a minimum distance equal to the distance from the
bluff edge to the 1.5 factor-of-safety-line, plus the distance that
the bluff might reasonably be expected to erode over 100 years. These
determinations, to be made by a state-licensed Certified Engineer
Geologist, Registered Civil Engineer, or Geotechnical Engineer, shall
be based on a site-specific evaluation of the long-term bluff retreat
rate at this site and shall include an allowance for possible acceleration
of historic bluff retreat rates due to sea level rise.
|
2.
|
If the bluff exhibits both a gross and surficial factor of safety
against landsliding of greater than 1.5, then development shall be
set back a minimum distance equal to the distance that the bluff might
reasonably be expected to erode over 100 years plus a ten foot buffer
to ensure that foundation elements are not actually undermined at
the end of this period. The determination of the distance that the
bluff might be expected to erode over 100 years is to be made by a
state-licensed Certified Engineer Geologist, Registered Civil Engineer
or Geotechnical Engineer, and shall be based on a site-specific evaluation
of the long-term bluff retreat rate at the site and shall include
an allowance for possible acceleration of historic bluff retreat rates
due to sea level rise.
|
For the purpose of this section, quantitative slope stability
analyses shall be undertaken as follows:
| |
1.
|
The analyses shall demonstrate a factor of safety greater than
or equal to 1.5 for the static condition and greater than or equal
to 1.1 for the seismic condition. Seismic analyses may be performed
by the pseudostatic method, but in any case shall demonstrate a permanent
displacement of less than 50 mm.
|
2.
|
Slope stability analyses shall be undertaken through cross-sections
modeling worst case geologic and slope gradient conditions. Analyses
shall include postulated failure surfaces such that both the overall
stability of the slope and the stability of the surficial units is
examined.

The effects of earthquakes on slope stability (seismic stability)
may be addressed through pseudostatic slope analyses assuming a horizontal
seismic coefficient of 0.20g, and should be evaluated in conformance
with the guidelines published by the American Society of Civil Engineers,
Los Angeles Section (ASCE/SCEC), "Recommended Practices for Implementation
of DMS Special Publication 117, Conditions for Analyzing and Mitigating
Landslide Hazards in California."
|
4.
|
All slope analyses shall be performed using shear strength parameters
(friction angle and cohesion), and unit weights determined from relatively
undisturbed samples collected at the site. The choice of shear strength
parameters shall be supported by direct shear tests, triaxial shear
test, or literature references.
|
5.
|
All slope stability analyses shall be undertaken with water
table or potentiometric surfaces for the highest potential ground
water conditions.
|
6.
|
If anisotropic conditions are assumed for any geologic unit,
strike and dip of weakness planes shall be provided, and shear strength
parameters for each orientation shall be supported by reference to
pertinent direct sheer tests, triaxial shear test, or literature.
|
7.
|
When planes of weakness are oriented normal to the slope or
dip into the slope, or when the strength of materials is considered
homogenous, circular failure surfaces shall be sought through a search
routine to analyze the factor of safety along postulated critical
failure surfaces. In general, methods that satisfy both force and
moment equilibrium (e.g., Spencer, Morgenstern-Price, and General
Limit Equilibrium) are preferred. Methods based on moment equilibrium
alone (e.g., Bishop's Method) also are acceptable. In general, methods
that solve only for force equilibrium (e.g., Janbu's method) are discouraged
due to their sensitivity to the ratio of normal to shear forces between
slices.
|
8.
|
If anisotropic conditions are assumed for units containing critical
failure surfaces determined above, and when planes of weakness are
inclined at angles ranging from nearly parallel to the slope to dipping
out of slope, factors of safety for translational failure surfaces
shall also be calculated. The use of a block failure model shall be
supported by geologic evidence for anisotropy in rock or soil strength.
Shear strength parameters for such weak surfaces shall be supported
through direct shear tests, triaxial shear test, or literature references.
|
9.
|
The selection of shear strength values is a critical component
to the evaluation of slope stability. Reference should be made to
the City of Malibu's current "Guidelines for the preparation of engineering
geologic and geotechnical engineering reports," and to the ASCE/SCEC
guidelines (see Section 9.4.D.3) when selecting shear strength parameters
and the selection should be based on these guidelines.
|
For the purpose of this section, the long-term average bluff
retreat rate shall be determined by the examination of historic records,
surveys, aerial photographs, published or unpublished studies, or
other evidence that unequivocally show the location of the bluff edge,
as defined in Chapter 2 of the Malibu LIP, through time. The long-term
bluff retreat rate is an historic average that accounts both for periods
of exceptionally high bluff retreat, such as during extreme storm
events, and for long periods of relatively little or no bluff retreat.
Accordingly, the time span used to calculate a site-specific long-term
bluff retreat rate shall be as long as possible, but in no case less
than 50 years. Further, the time interval examined shall include the
strong El Niño winters of 1982-1983, 1994-1995 and 1997-1998.
|
For all other proposed temporary events, a coastal development
permit must be obtained prior to the event.
|
In any of these circumstances, the applicant must seek to file
an application with the Coastal Commission for an amendment to the
Commission-issued coastal development permit and authorization for
the proposed new development or modification to existing development.
The Coastal Commission will determine whether the application for
amendment shall be accepted for filing pursuant to the provisions
of Title 14 California Code of Regulations, Section 13166.
|
The proposed project complies with all applicable requirements
of state and local law.
|
A.
|
The proposed OWTS is consistent with the LCP and all applicable
LCP provisions, local laws and regulations regarding OWTSs; and
|
B.
|
The proposed OWTS does not require a new or upgraded shoreline
protective device; and
|
C.
|
The proposed OWTS is necessary to protect public health and/or
improve water quality; and
|
D.
|
The proposed OWTS CDP has been conditioned in accordance with
the LCP.
|
Upon approving an OWTS CDP, the Planning Manager shall issue
a written document that at a minimum includes the following information:
| |
A.
|
Location of the project;
|
B.
|
The date of issuance;
|

|
F.
|
Findings.
|
All required approvals certifying that these conditions are
met shall be obtained;
|
In each of the above cases, the permit shall also require transfer
of development credits pursuant to Chapter 7 of the Malibu LIP.
|
If the requirements of Section 15.3 (D)(1), 15.3 (D)(2) or 15.3 (D)(3) of the Malibu LIP are not met, a coastal development permit for the proposed land division shall be denied.
|
For a merger initiated by the City, the procedural requirements
for merger of parcels set forth in the Subdivision Map Act shall be
complied with. A merger of parcels shall become effective when the
City records with the County recorder, a notice of merger, specifying
the name of the record owner and particularly describing the property
merged.

1 Systems that provide secondary
or tertiary effluent treatment prior to discharge to the subsurface
effluent dispersal systems are not required to meet these minimum
horizontal setback requirements provided that no parts of the OWTS
are, at any time, submerged or exposed to direct contact with these
surface water bodies. In the case of beachfront developments and redevelopments,
the OWTS shall, to the maximum extent feasible, be located at the
farthest point from the Ocean on a parcel to avoid the construction
of protective structures such as sea walls and bulkheads.
|
2 Where publicly owned storm drainage
pipes run across a property rendering it impossible to meet these
minimum horizontal setback requirements, the effluent dispersal system
is allowed to be located within 50 feet of the pipes provided that
these pipes are positioned vertically higher than the bottom of the
effluent dispersal system or the applicant demonstrates that the pipes
are sealed so that there is no possibility for shallow groundwater
to infiltrate the storm drain.
|
3 Where a California Registered Geologist
finds and states in writing that the stability of the fill or cut
bank will not be compromised by a shorter horizontal separation and
that a shorter horizontal separation will not result in sewage effluent
daylighting, a shorter horizontal setback for the effluent dispersal
system can be used per the said geologist's recommendation.
