See Agenda Bill No. 16,222 on file with the City Clerk
EXHIBITS:
1. Ordinance No. NS-589
i All new development, substantial rehabilitation, redevelopment or related
activity, shall be designed and conducted in compliance with all applicable local
ordinances including Chapter 15.12 of the Carlsbad Municipal Code Stormwater
Management and Discharge Control Ordinance, the Standard Specifications for
Public Works Construction when performing public work, and applicable provisions
of the NPDES General Permit for Storm Water Discharges Associated with
Construction Activity issued by the State Water Resources Control Board (State
Board Order No. 92-OS-DWQ), and any subsequent amendments, and the San Diego
NPDES Municipal Storm Water Permit issued to San Diego County and Cities by the
California Regional Water Quality Control Board (Regional Board Order No. 9042)
and any amendment, revision or re-issuance thereof.
In addition the following shall apply to development within Kelly Ranch:
New development and significant redevelopment of private and publicly-owned
properties, must incorporate design elements and/or Best Management Practices
(BMPs) which will effectively prevent runoff contamination, and minimize runoff
volume from the site in the developed condition. to the greatest extent feasible. At a
minimum, the following specific requirements shall be applied to development of
type and/or intensity listed below:
Residential Development
I Development plans for, or which include residential housing development with
greater than 10 housing units shall include a drainage and polluted runoff control plan
prepared by a licensed engineer, designed to infiltrate, filter or treat the volume of
nmoff produced from each and every storm event up to and including the 85th
percentile 24-Hour runoff event, prior to conveying runoff in excess of this standard
to the storm water conveyance system. The plan shall be reviewed and approved by
the consulting soils engineer or engineering geologist to ensure the plan is in
conformance with their recommendations. The plan shall be designed in consideration
of the following criteria, and approved prior to issuance of a coastal development
pennit:
i. Maximize the percentage of permeable surfaces and green space to allow
more percolation of runoff into the ground and /or design site with the capacity to
convey or store peak runoff from a storm and release it at a slow rate so as to
minimize the peak discharge into storm drains or receiving water bodies;
ii. Use porous materials for or near walkways and driveways where feasible;
. . . 111. Incorporate design elements which will serve to reduce directly connected
impervious area where feasible. Options include the use of alternative design features
such as concrete grid driveways, and/or pavers for walkways.
iv. Runoff from driveways, streets and other impervious surfaces shall be
collected and directed through a system of vegetated and/or gravel filter strips or other

media devices, where feasible. Selected filter elements shall be designed to 1) trap
sediment, particulates and other solids and 2) remove or mitigate contaminates
through infiltration and/or biological uptake. The drainage system shall also be
designed to convey and discharge runoff from the building site in a non-erosive
manner.
V. Selected BMPs shall be engineered and constructed in accordance with the
design specifications and guidance contained in the California Stormwater Best
Management Practices Handbook (Municipal).
vi. The plan must include provisions for regular inspection and maintenance
of structura.l BMPs, for the life of the project.
Parking Lots
Development plans for, or which include parking lots greater than 5,000 sq. ft. in size
and/or with 25 or more parking spaces, susceptible to stormwater, shall incorporate
BMPs effective at removing or mitigating potential pollutants of concern such as oil,
grease, hydrocarbons, heavy metals, and particulates from stormwater leaving the
developed site, prior to such runoff entering the stormwater conveyance system, or
any receiving water body. Options to meet this requirement include the use of
vegetative filter strips or other media filter devices, clarifiers, grassy swales or berms,
vacuum devices or a .combination thereof. Selected BMPs shall be designed to
collectively infiltrate, filter or treat the volume of runoff produced by each and every
storm event up to and including the 85* percentile 24-Hour runoff event. BMPs shah
be engineered and constructed in accordance with the guidance and specifications
provided in the California Stormwater Best Management Handbooks Handbooks
(Commercial and Industrial).
All Development
A public education program shah be designed to raise the level of awareness of water
quality issues around the lagoon including such elements as catch basin stenciling and
public awareness signs.
A landscape management plan shall be created that includes herbicide/pesticide
management.
Such measures shall be incorporated into project design through a water quality/urban
runoff control plan and monitoring program to ensure the discharge from all proposed
outlets is consistent with local and regional standards. Such measures shall be
required as a condition of coastal development permit approval at the subdivision
stage

SECTION VII: That Section 21.203.040 of the Carlsbad Municipal Code is
amended by the addition of Subsection 21.203.040 (G) to read as follows:
G. Within the Kelly Ranch. scenic public views from Interstate 5, Cannon Road and
Agua Hedionda Lagoon shall be preserved, as feasible, through the following
measures:
1. Landscaping and Setbacks: Use of trees or fire retardant vegetation with
substantial height as a landscape screen and/or setbacks from the
ridgelines and open space areas;
2. Building Colors: Exterior wall and roof colors shall be of low intensity
earth or vegetative tones. Stucco with accent materials such as tile, natural
stone, or other compatible natural building materials shall be preferred.
Roof colors shall be low intensity colors which blend with the
environmental setting of the project;
3. Residential Building Height: Maximum height limits and variation in roof
heights shall be utilized, as necessary, to minimize visibility of structures
from scenic public roadways, public vista points and public trails.
SECTION VIII: That Section 21.203.040 of the Carlsbad Municipal Code is
amended by the addition of Subsection 2 1.203.040 (II) to read as follows:
H. Within the Kelly Ranch, landscaping shall be utilized as a visual buffer and be
compatible with the surrounding native vegetation and preserved open space by
incorporation of the following measures:
1. All residential development shall be required to identify and implement a
landscaping plan that provides for installation of plant species that are
native or non-invasive and drought tolerant to the maximum extent
feasible. Ornamental (non-invasive) vegetation shall be permitted in the
interior of residential subdivisions only;
2. Approved landscaping shall be installed immediately upon completion of
construction and maintained by the property owners in good growing
condition for the life of the development;
3.
4.
Landscape screening of structures, including specimen trees and fire
retardant vegetation of substantial height, shall be required to screen and
soften the view of structures from I-5, Cannon Road, Agua Hedionda
Lagoon, public trails and public vista points;
The landscape treatment shall cause the development to blend in with the
natural setting and present a visually cohesive appearance as viewed from
Agua Hedionda Lagoon, Cannon Road and Interstate 5
