A REPORT TO THE PLANNING COMMISSION '
Single Family Coastal Development Permit
P.C. AGENDA OF: October 7,1998
Application complete date: April 13, 1998
Project Planner: Van Lynch
Project Engineer: David Rick
SUBJECT: CDP 98-30/HDP 98-06 - BARBOUR RESIDENCE - Request for approval of a
Coastal Development Permit and Hillside Development Permit to allow for the
construction of a single family residence within the City's Coastal Zone located
on the south side of Hoover Street, west of Adams Street and east of Highland
Drive within Local Facilities Management Zone 1.
I. RECOMMENDATION
That the Planning Commission ADOPT Planning Commission Resolution No. 4406
APPROVING the Negative Declaration, and Planning Commission Resolutions No. 4407 and
4408 APPROVING a Coastal Development Permit and a Hillside Development Permit based
upon the findings and subject to the conditions contained therein.
11. INTRODUCTION
Pursuant to Section 21.201.030 of the Carlsbad Municipal Code, the construction of a single
family home within the City's Coastal Zone requires the processing and approval of a Coastal
Development Permit (CDP). The CDP application was reviewed for consistency with Local
Coastal Program policies and implementation. The project also requires a Hillside Development
Permit because of the sites steep topography. There are no unresolved issues. The staff
recommended approval with conditions is supported by the analysis as follows.
111. PROJECT DESCRIPTION AND BACKGROUND
Proiect Site/Setting: The project consists of developing an infill lot located on the south side of
Hoover Street between Adams Street and Highland Drive as shown on the attached Location
Map. The lot area is .344 acres (1 5,000 square feet).
Proposed Residential Construction: New two story residential structure with 35 10 square feet of
living area, 768 garage area and 1,250 square feet of balcony and deck area totaling 5528 square
feet of new construction.
Proposed Grading: 1750 cubic yards of grading is proposed (300 cu. yds. fill, 1750 cu. yds cut
and 1450 cu. yds export) with this project and a grading permit will be required.

IV. ANALYSIS
As shown on the Coastal Development Compliance Table below, the proposed development is in
compliance with all applicable regulations. Building permits may be issued subject to the
conditions contained in Planning Commission Resolutions No. 4406,4407 and 4408.
Review of Required Coastal Findings
1. Conformance with the Certified Local Coastal Program and all applicable policies.
The project is located in the Mello I1 Local Coastal Program Segment.
The project proposes the construction of a single family residence in an area designated
for single family development. The LCP Land Use Plan designates the subject site for
Residential Low-Medium density development.
2. Coastal Overlay Zones.
The subject site is located in the Coastal Resource Protection Overlay Zone, and includes
steep slopes that are greater than 25% gradient. These slope areas as identified on the
slope analysis map are small isolated manufactured slopes with elevation changes of 4 to
6 feet, which were created during previous grading and are not a natural condition.
Slopes have been created from public roadway work and private grading for pad
development and driveway cuts. The slopes do not support any endangered plant/animal
species andor coastal sage scrub and chaparral plant communities and therefore are not
considered “dual criteria” slopes. There are provisions in the coastal resource protection
zone that allow all other steep slopes to be developed. The appropriate findings to allow
for the development’of the slope areas are as follows:
a. A soils investigation conducted by Barry and Associates Geotechnical
Engineering, September 16, 1997, has determined that the slope areas are not

considered subject to seismically induced soil liquefaction and soil instability
due to such factors as soil type, density and lack of groundwater.
The grading of the slopes are essential to the development design in that the
site must have access from Hoover Street. The slopes must be graded to
provide a driveway to gain access to the site.
Slope disturbance will not result in substantial damage or alteration to major
wildlife habitat or native vegetation areas in that the site is an infill
development with single family homes to the north and east, paved driveway
to the south and a public street to the west.
The area is less that ten acres in size (.344 acres) and will not interrupt
significant wildlife corridors.
The site does not contain north facing slopes which are generally less stable
and contain more extensive vegetation.
Hillside Development Regulations
The project contains slopes of 15% or greater and an elevation differential of 15’, therefore, a
Hillside Development Permit is required. Because the project site contains isolated slope areas
over 40% that are less than 15 feet in height and that do not comprise an area of over 4000 square
feet, these areas are excluded fiom the requirements of the Hillside Development Ordinance
pursuant to Section 2 1.95.090 of the Carlsbad Municipal Code. Subsection 21.95.060(a) of the
Hillside Ordinance requires that all development on slopes of 25% and greater within the coastal
zone shall comply with the coastal resource protection overlay zone. As discussed above, the
project as proposed-is in compliance with the overlay zone. The table below indicates how the
project complies with the applicable requirements of the Hillside Development Ordinance in
effect in the coastal zone (unrevised version):
