MEMORANDUM
DATE: April 14, 1993
TO~~irman and Members of the Planning Commission
F~Brad Buller, City Planner
~Y: -- Dan Coleman, Principal Planner
SUBJECT: TRANSITION OF DENSITY FOR RESIDENTIAL PROJECTS
This memo is intended to facilitate Commission discussion on this item
by providing copies of existing standards and guidelines for proper
transition of density. As you can see from the attached excerpts from
the Development Code and planned community texts, there is a wealth of
regulation addressing this important site planning issue.
Two approaches are evident: 1) definitive, objective standards, such as
increased setback and height restrictions at property line, and 2)
general "good neighbor" policy statements regarding the need for
"harmony" between land uses of differing intensity (i.e., height density
next to lower density).

That standard street widths be established as follows:
Density Range
Up to 2 du/ae
2-8 du/ac
Street Pavement Width
Conditions
36-foot standard;
reduced width may be
nilowed subject to
Design/Technical Review(a)
Reduced width requires
availability of suffi-
cient visitor parking
plus minimum on-site
spaces as required by
the Development Code.
36 foot standard;
reduced width may be
nllowed subject to
Design/Technical Review(a)
Reduced width requires
availability of suffi-
cient visitor parking
plus minimum on-site
spa,es as required by
the Development Code.
8 + du/ac 28 feet minimum Parking subject to Code
and Design/Technical
Review to insure adequate
visitor parking.
(a) Reduced pavement width may be nilowed where innovative site planning techniques
such as semi-detached or attached houses, clustering, zero lot line, and skewed house
plotting provide streetscape variety and visual interest, increases lot usability, or where
necessary to preserve rural character, significant natural features, historic landmarks or
to minimize cut and fill grading in hillside areas.
O. Zero Lot Line. The dwelling unit may be placed on one interior side property line
with a zero (0) setback, and the dwelling unit setback on the other interior side
property line shall be a minimum of ten (10) feet, excluding the connecting
elements such as fences, walls, and trellises. Pools, de.ks, garden features, and
other similsr elements sbn]! be permitted within the ten (10) foot setback area,
provided, however, no structure, with the exception of fences or w~l]s, shall be
placed within easements required below. Where adjacent Zero Lot Line dwellings
are not constructed against a common lot line, the builder or developer must
provide for a perpetual wall maintenance easement of five feet in width along the
adjacent lot and parn]lel with such w~!!.
Absolute Policies are intended to address the most critical issues associated with
idential development. These include assuring neighborhood compatibility,
pliance with adopted plans, adequacy of public facilities and services, and
teetion of the environment and public health. Eaeh project must satisfy all absolute
icies before approval can be granted. These policies are used in evaluation of a
esidential project as described in Section 17.06.030 of thi~it.l~e~/~~/~~
Section 17.08.050
Plans & Policies
1. The Project is consistent with the adopted General Plan, Land Use Plan,
Development Code, and all applicable Specific Plans.
2. The Project is consistent with the adopted Master Plan of Trails.
3. The Project is consistent with the adopted Parks and Recreation Plan.
4. The Project is consistent with the adopted Circulation Plan.

/ 1. The Project is compatible with and sensitive to the immediate environment
~ of the site and neighborhood relative to architectural design; scale, bulk,
~ density and unit size; identity and neighborhood character; building
orientation and setback; grading; and visual integrity. ' _
~, 2. The conflicts that are presumed to exist between the proposed development
~ and surrounding land uses as described in Table 17.08.050-F pertaining to
~ "Land Use Conflicts", have been effectively mitigated in the~_r~oject design.
3. The Project is designed so that the additional traffic generated does not
have significant adverse impact on surrounding development.
Section 17.08.050
,,
The Project eontairm streamside woodland associations, identified as a
significant natural resource in Figure IV-2 of the General Plan, and site
investigations have been completed, and mitigation measures proposed
(ineludiag clustering) to mitigate impacts upon riparian community.
The Project is located on a site or contains a structure or other feature
which is designated as a historic landmark, and provision has been made for
preservation of said landmark in accordance with the Historic Preservation
Ordinanoe.
The Project site is designated by the General Plan as Hillside Residential, or
is a hillside condition (defined as having natural slopes 8 peroent or greater),
and environmental studies have been conducted to determine land holding
capacity and site development constraints, and the proposed density is no
greater than two units per net buildable acre.
The Project site is designated by the General Plan as Open Space, and
development has been concentrated to preserve open space, and the proposed
density is no greater than an average density of one unit per 40 acres.
The Project promotes energy efficiency through the use of energy efficient
building design (e.g., south facing windows, energy conserving building
materials and appliances, etc.) and site planning (e.g., east-west aligned
units, landscaping for solar access, etc.).
8. The Project contains trees protected by the Rancho Cueamonga Municipal
Code that are worthy of preservation; an application for a tree removal
permit and report have been submitted and healthy trees are preserved

between land u,s. ~, t~e, of mitestim me,.~, list~ in ~, foUowi~ ,etio~ ~
are ~e desi~ t~ that should be employ~ either ~pa~tely or ~ combination to ~
mitigate existing or potential land use conflicts. The Absolute Policies require that
i/such conflicts be effectively mitigated in the project design.
1. Land Use Conflict Mitt~ation Measures
(a) Open Space Setbacks. By providing an open space buffer between
eonflietin~ land uses conflicts ran often be avoided. The width of the
buffer requtred wiU depend on the severtty of conflict and the extent
of landscaping. To work effeettvely, the ownership, use, and
maintenance of the open space buffer must be clearly defined.
(b)
Landscaping and Tooc~raphie Changes. As part of an open space
buffer or as a treatment of land immediately adjacent to buildings,
landscaping ran be used to recktee conflicts.
(c) Define plantings of evet~Teens can provide a visual buffer.
(x)
Sensitive landscaping ran soften the sharp visual contrast
between two abutting land uses by subduing the differences in
architecture and bulk and by providtng a gradual transition
rather than a harsh edge between uses.
(2)
Dense growth of plants can be visually appealing but also can
be used to discourage unwanted and unsafe pedestrian or
bicycle arcres between land uses.
~J -82- "revised 3/8/90"
(d)
(e)
(f)
Section 17.08.050
(3) Landscaping can be used in cembination with other mitigation
measures, such 8s reducing the width of open space buffer
required and soften the visual conflict created by safety and
security fences.
(4) Recontouring of the land can alter views, subdue sounds,
reduce glare, change the sense of proximity, and channel
pedestrian travel.
Orientation. The strict spatial proximity between land uses and the
apparent or functional proximity can be very different depending on
the orientation of buildings and activities in the two land uses.
(1) The buildings themselves can cause a buffer to be created by
effectively turning their backs on each other -- orienting
views, access and principal activities away from the other land
use. Care must be taken, however, that a hazardous and
unaesthetic "no-marts" land is not created in the process.
(2)
Alternately, the intervening space can be eliminated
altogether if the two buildings share a common back waU.
An entire site plan ~ oriented so that the activities and-'~
functions are aUgned hierarchieaUy -- placing those least~
cempatible furthest from the common boundary between land{
uses and those most compatible near that boundary (i.e., single/
story adjacent to single story).
Barriers and Alleviation. It may be appropriate and necessary to use
physical barriers to prevent the undesirable attributes of one land use
from affecting the people and activities in the edjaeent land use.
(l) Pences, walls and betres can prevent the passage of people into
areas that would be unsafe or insecure.
(2) Light and noise can also be mitigated through physical barriers
such as fences, walls, betres, screens and landscaping.
Architectural Compatibility. In addition to the architectural
considerations involved in mitigation through orientation, the
architectural design of buildings can reduce conflict and promote
compatibility.
(1)
Materiml% colors, scale, and prominence of buildings in
adjacent land uses can he coordinated so there is a gradual
transition from one land use to another rather than a sharp and
displeasing contrast. Purely aesthetic details that are "tacked"
onto a building to cover up land use conflicts, however, will
cause more harm than good.
(2)
The architectural compatibility should rise from a total
consideration of the function of each land use and the function
of the space between them.

from straets through combinations of moundJng, landscaping, low profile wal~s
and grade separations. The design of parldng areas should also mqnqmJze auto
nMse, glare, end increases in ambient at~ temperetune. T~s can be
accomplished through sound walls, screening w%th ~ences or hedges, t~ees, and
separation o~ parktrig spaces and oYlveways from residence~
Stte Design: Openness, ~duced structure mass and convenlence of

UBJECT: RESIDENTIAL DEVELOPMENT - VARIATION IN LOT SIZES
Currently, the Development Code mandates variety in lot size in new
subdivisions by requiring an average lot size 1,000 square feet greater
(500 square feet under Option Standards) than the minimum lot size in the
Low-Medium Residential District. The average could be raised. Lot size
variety is also indirectly encouraged by using curvilinear streets and
cul-de-sacs. However, if the lot width does not vary, then increasing the
average lot size will not impact the streetscape appearance. Lot width
could be amended to require an average greater than the current minimum.
Copies of the Development Code and planned community regulations are
attached.

RESIDENTIAL DESIGN GUIDELINES
S I N G LEFAM I L Y
Single family residential development should promote an attractive streetscape through architectural and site "~
planning design elements that create vadety and interest. Housing tracts characterized by repititious street ~
scenes of nearly identical two-story houses built at the minimum setback lines are not desirable. Generally, it ~
_requires_the us.e of a combination of des~n concepts or solutions to achieve the goal of creating varied, J
i~ting and Sactive streetscape~,~ ~ ~
El Excession repetition of single family homes with near identical floorplans and elevations is discouraged.
Floorplans and elevations should be varied as follows:
Number of Single Minimum Number of Minimum Number of
Family Dwellings' Floorplans* Elevations / Floorplan**
5-10 3 2
11-20 4 3
21-40 5 3
41-60 6 4
61-80 7 4
81-100 8 4
Over 100 1 Additonal For
Each 40 DU's Over 100
* The following may be counted as additional floorplans:
Reverse footprints.
Alternate orientation o~ 90 de~p~c= or greater.
Alternate garage orientation (i.e., side entry or detached).
Reverse footprints shall not count as additional elevations~ Variations in the
following design elements which create a significant difference in streetscape
appearance shall count as additional elevations:
1. Plans with different architectural styles.
2. Plans with changes in massing and scale.
3. Plans with roof ridges running in different directions.
~ 4. Plans~th sig~ficant changes in.,,~..~.~...~_~a~pl~rOpriate robie..
~Lot $~t width~ons~ encouraged in order to pmvide designers with opportunities to "~"~'"'"\
1 dmc u e sign~i' cant variations in house orientations that balances livable open space with mass. For example,
wider lot creates oppoprtunity for greater separation between homes and accomodates side entry garages.
Significant variations in setback and footprint orientation are encouraged.
El House size and mass should be proportional to the lot size a~xi lot dimensions. Houses which project a
two sWry volume straight up at the minimum setbacks on small lots are inappropriate.
Two-story houses on comer lots should have extra deep setbacks. · ·
