The City of Carlsbad Planning Division A REPORT TO THE PLANNING COMMISSION
Single Family Coastal Development Permit
Item No.
Application complete date: October 31, 2017
P.C. AGENDA OF: January 17, 2018 Project Planner: Paul Dan
Project Engineer: David Rick
SUBJECT: CDP 2017-0051 (DEV2017-0168) – HOLSTEIN RESIDENCE – Request for approval of a
Coastal Development Permit to allow for the addition of 534 square feet of habitable
space to an existing single-family residence within the Mello II Segment of the city’s Local
Coastal Program located at 4244 Park Drive within Local Facilities Management Zone 1.
The project site is not within the appealable area of the California Coastal Commission.
The City Planner has determined that the project belongs to a class of projects that the
State Secretary for Resources has found do not have a significant impact on the
environment, and it is therefore categorically exempt from the requirement for the
preparation of environmental documents pursuant to Section 15301(e), additions to an
existing structure, of the state CEQA Guidelines.
I. RECOMMENDATION
That the Planning Commission ADOPT Planning Commission Resolution No. 7284 APPROVING Coastal
Development Permit CDP 2017-0051 based upon the findings and subject to the conditions contained
therein.
II. PROJECT DESCRIPTION AND BACKGROUND
Project Site/Setting: The 0.22 acre (9,583 square feet) project site is located at 4244 Park Drive as shown
on the attached location map. The topography of the site is relatively flat with a slight incline towards the
north of the property. The neighborhood is characterized by one- and two-story single-family residences,
with two-car garages. The project would require no grading and no removal of native vegetation. Table
“A” below includes the General Plan designations, zoning and current land uses of the project site and
surrounding properties.
TABLE A
Location General Plan Designation Zoning Current Land Use
Site R-4 R-1 Single-family residence
North R-4 R-1 Single-family residence
South R-4 R-1 Single-family residence
East R-4 R-1 Single-family residence
West R-4 R-1 Single-family residence
Proposed Residential Construction: The project consists of 534 square feet of new habitable space
additions to an existing 1,004 square foot one-story single-family residence. The additions include a new
living room addition, and expansion of the kitchen and dining room. The residence would remain one-
story with no increase in height.

Proposed Grading: Estimated grading quantities include 0 cubic yards (cy) of cut with 0 cy of fill. A grading
permit will not be required for this project.
III. ANALYSIS
The project is subject to the following regulations and requirements:
A. R-4 Residential General Plan Land Use Designation;
B. One-Family (R-1) Residential Zone (CMC Chapter 21.10);
C. Coastal Development Regulations for the Mello II Segment of the Local Coastal Program (CMC
Section 21.201) and the Coastal Resource Protection Overlay Zone (CMC Section 21.203);
D. Inclusionary Housing Ordinance (CMC Chapter 21.85); and
E. Growth Management (CMC Chapter 21.90).
The recommendation for approval of this project was developed by analyzing the project’s consistency
with the applicable city regulations and policies. The project’s compliance with each of the above
regulations is discussed in detail in the sections below.
A. R-4 Residential General Plan Land Use Designation
The project site has a General Plan Land Use designation of R-4, which allows the development of one-
family dwellings at a density of 0-4 dwelling units per acre with a Growth Management Control Point
(GMCP) of 3.2 dwelling units per acre (du/acre). The project has a net acreage of 0.22, which would permit
.07 dwelling units. Per CMC Section 21.53.230(e), fractional units of 0.5 or greater at the GMCP density
are round up. The existing single-family residence is consistent with the R-4 General Plan Land Use
designation.
B. One-Family (R-1) Residential Zone (CMC Chapter 21.10)
The project is required to comply with all applicable regulations and development standards of the
Carlsbad Municipal Code (CMC) including the One-Family Residential (R-1) zone. The proposed project
meets or exceeds all applicable requirements of the R-1 zone (Shown in Table B below).
TABLE B – R-1 ZONE DEVELOPMENT STANDARDS
STANDARD REQUIRED/ALLOWED PROPOSED
Front Yard Setback 20’ 27’
Side Yard Setback 7’-5” 13’-11”
Rear Yard Setback 15’ 39’-3”
Max Building Height 30’ with >3:12 roof pitch 13’-2”
Lot Coverage 40 percent maximum 20 percent
Parking Two-car garage (20’X20’) Two-car garage (20’X22’)
C. Conformance with the Coastal Development Regulations for the Mello II Segment of the Local
Coastal Program (CMC Chapter 21.201) and the Coastal Resource Overlay Zone (CMC Chapter 21.
203)
The project site is located within the Mello II Segment of the Local Coastal Program and is not within the
appeals jurisdiction. The site is also located within and subject to the Coastal Resource Protection Overlay
Zone. The project’s compliance with each of these programs and ordinances is discussed below:
CDP 2017-0051 (DEV2017-0168) – HOLSTEIN RESIDENCE

1. Mello II Segment of the Certified Local Coastal Program and all applicable policies
The subject site has a Local Coastal Program (LCP) Land Use Plan designation of R-4 Residential, which
allows for a density of 0 to 4 du/acre and 3.2 du/acre at the Growth Management Control Point (GMCP).
At the R-4 GMCP, 0.7 dwelling units would be permitted on this 0.22 acre (net developable) property.
However, per CMC Section 21.53.230(e), fractional units of 0.5 or greater at the GMCP density are round
up. The existing single-family residence is consistent with the R-4 General Plan Land Use designation.
Therefore, the existing single-family residence and proposed additions are consistent with the R-4 LCP
Land Use Plan designation.
The project consists of additions to an existing single-family residence that include 534 square feet of
habitable space in an area designated for residential development. The additions to the existing single-
story residence will not obstruct views of the coastline as seen from public lands or the public right-of-
way, or otherwise damage the visual beauty of the coastal zone. No agricultural uses currently exist on
the previously developed site, nor are there any sensitive resources located on the site. The proposed
additions are not located in an area of known geologic instability or flood hazard. Since the site does not
have frontage along the coastline, no public opportunities for coastal shoreline access are available from
the subject site. Furthermore, the residentially designated site is not suited for water-oriented recreation
activities.
2. Coastal Resource Protection Overlay Zone
The project is consistent with the provisions of the Coastal Resource Protection Overlay Zone (CMC
Chapter 21.203 of the Zoning Ordinance) in that the project will adhere to the City’s Master Drainage Plan,
Grading Ordinance, Storm Water Ordinance, BMP Design Manual and Jurisdictional Runoff Management
Program (JRMP) to avoid increased urban run-off, pollutants and soil erosion. The subject property does
not include steep slopes (equal to or greater than 25 percent gradient) or native vegetation.
D. Inclusionary Housing Ordinance (CMC Chapter 21.85)
Pursuant to CMC Chapter 21.85.030.D.1, a project may be exempt from the inclusionary housing
requirement if an existing residence is altered, improved, restored, repaired, expanded, or extended,
provided that the number of units is not increased. Since there will not be an increase in the number of
units on the property, the project is exempt from the inclusionary housing requirement.
E. Growth Management
The proposed project is located within Local Facilities Management Zone 1 in the Northwest Quadrant of
the city. No impacts are associated with the project as the project consists of a remodel and additions to
an existing residence and no new impacts will be generated.
IV. ENVIRONMENTAL REVIEW
This project is exempt from CEQA per the exemptions listed below:
(1) Section 15301(e) of CEQA (Class 1) exempts additions to an existing structure.
A Notice of Exemption will be filed by the City Planner upon project approval.
