project boundary. The counter staff can assist you in determining the appropriate
assessors parcel number(s).
5. Local Facilities Management Zone: Write the number of the facilities management
zone within which your project is located. Ask for counter assistance in determining
which facility zone your project is located. It is important to know which facility
zone includes your project. Each facility zone must have an adopted local facilities
management plan before applications can be accepted by the City. Additionally, the
adopted facility plan for your zone may contain significant public facility
requirements which must be met before your project may be accepted as complete
or before construction permits are issued.
6. Existing General Plan Designation: Write down the General Plan Designation(s) for
the property covered by your proposed project. Ask for counter assistance if you do
not know your general plan designation.
7. Proposed General Plan Designation: Required only if your project involves a request
for a general plan amendment. If so, write in the proposed general plan designation
for the property.
8. Existing Zoning: Write down the existing zone plan designation for your proposed
project property. Ask counter staff for assistance if you do not know your zone
designation.

II. STATEMENT OF NON-SIGNIFICANT ENVIRONMENTAL EFFECTS
If you have answered yes to any of the questions in Section I but think the activity will have
no significant environmental effects, indicate your reasons below:
For the purposes of this Part I analysis, the "project" is considered to be all of the
previously described Villages, for a total of 669 dwelling units on 290.4 acres. Individual
villages will be discussed separately where necessary.
1) The project will not significantly impact or change present or future land uses in the
vicinity of the project area because the area is part of a larger developing residential
master plan. The Calavera Hills Master Plan includes 800 acres and has
approximately 1100 existing dwelling units. The proposed project has been planned
for both in the master plan and the Zone 7 LFMP. As shown on table for question
3.a., the proposed number of units is 126 fewer than what is allowable per the Zone
7 Local Facilities Management Plan. One change in product type occurs in Village
H, which is proposed for 13 single family custom estates instead of 42 multi-family
units, as permitted by the Local Facilities Management Plan based on this Village's
Growth Control Plan. This is not considered a significant land use change.
2) The proposed project, when implemented, will effect the use of the Calavera Hills
Community Park. The effect of the development will increase the demand on this
park and other future City parks in the Northeast Quadrant to the level anticipated
in the City's Growth Management Program. Areas of aesthetic value which are
considered significant have been preserved as part of the existing master plan and
also through detailed constraints mapping for Zone 7, and will not be impacted by
the proposed project.
3) The proposed project will not affect the functioning of an established neighborhood
because the new villages are in compliance the Master Plan and will provide any
necessary infrastructure improvements or upgrades to ensure that public services will
meet required standards. To avoid impacting existing neighborhoods the proposed
tentative maps have been designed to gain access from existing and future arterial
streets rather than existing local streets. Development of the proposed projects will
actually improve access to the existing neighborhoods by the constructions of College
Avenue and the remainder of Tamarack Avenue which will provide a linkage to the
existing College Avenue and Highway 78 in Oceanside.
4) No community residents will be displaced because the project area is currently
vacant.'
5) The proposed tentative maps could increase the number of low and moderate priced
housing in the City of Carlsbad. The Calavera Hills Master Plan requires that
"Villages K and L-2, by including lower cost condominiums for sale and/or rental
housing, provide the City with affordable housing and housing for the elderly." The
applicant, by providing smaller condominium units in Village K, will fulfill this
requirement and provide moderately priced housing in this portion of Carlsbad.
. .
6) Existing housing will not be affected. The proposed project will "fill" a demand for
additional housing, not "create" a demand. This question is more applicable for non-
residential proposals.
7) The natural features of the subject property are primarily rolling hills and ravines
and steep slopes and associated biological habitat. Calavera Lake also is in the
vicinity. All of these features are common to Carlsbad and the rest of the county.
8) An updated archaeology study was done for the entire master plan area in March,
1990. This study found one potentially significant site in Village W that required
additional testing. If it is determined that this site will be impacted by the
development of Village W it will be evaluated in accordance with the
recommendations of the letter dated May 22, 1990, attached to this document.
9) No scarce natural resources are known to exist in the project area and thus, their
use, extraction or conservation will not be affected.
10) A biological survey was conducted on the property in January, February, May and
June 1990. The results of those surveys are summarized in the attached report. The
major impacts are summarized as follows:
11) Several sensitive biological features may be impacted by the proposed project.
Wetland habitat of 0.11 acre of riparian scrub will be impacted where Elm Avenue
bisects Village H. The applicant will be required to obtain a California Department
of Fish and Game Streambed Alteration Agreement for the elimination of this area.
The enhancement of the existing wetland habitat in Village H or Village X would
be appropriate mitigation for the loss of 0.11 acre of riparian scrub eliminated by
the widening of Elm Avenue.
Approximately 8.9 acres of coastal sage dominated by artemisia and encompassing
a territory for a single pair of California Gnatcatchers may be impacted by the
development of Village K.
Three water line easements associated with development of Village Q will pass
through the California gnatcatcher territory found in Village K. Two of the
easements will follow existing dirt roads or disturbed areas and one easement is for
the most part, outside of the gnatcatcher territory. While the impact to the preferred
habitat of the existing gnatcatcher territory in Village K is not significantly impacted
by the three easements, it is not known if the one pair of gnatcatchers will remain
after construction of these waterlines are completed. It is recommended that an
additional survey of this area be conducted after the installation of the permitted
water lines. Based on the results of this subsequent survey, the need for mitigation
will be determined. The attached biological survey dated June 1990 provides three
possible mitigation measures if mitigation is deemed necessary.
Several other sensitive plant species will be impacted by proposed development but
not significantly.
.
The impacts to birds of prey and sensitive mammal and reptile species potentially
present and present on-site is considered an insignificant cumulative adverse impact.
For additional details see the attached Biological Report dated June 1990.
12) The proposed project will drain primarily to Aqua Hedionda Lagoon (95%) with a
small portion of Village 12 draining north to Buena Vista Lagoon. To ensure that
impacts are insignificant the applicant will comply with all of the City of Carlsbad's
standard engineering practices to control the amounts and velocities of drainage from
this project. During the construction phase water quality impacts will be mitigated
to a level of insignificance by the construction of erosion control devices to the
satisfaction of the City Engineer.
13) Agricultural lands will not be impacted by the proposed project because the area is
not used for farming. The project is adjacent to the existing residential development
of Calavera Hills. In terms of prime agricultural soils, a review of the soils map in
the previous EW (#403) prepared for the master plan shows that no prime soils are
found within the proposed project area and that past farming efforts were
unsuccessful because the soils were thin, extremely rocky and almost unfarmable.
14) The proposed project will not act as a catalyst to encourage development of presently
undeveloped areas because the project is implementing the Calavera Hills Master
Plan, part of which has already been developed. This area has always been
designated for residential development by the City of Carlsbad's General Plan and
the proposed development is in conformance with this plan. Other major
landholdings in the Northeast Quadrant of the City have been in the planning stages
for several years and will continue that process regardless of the development activity
on this site.
15) The proposed tentative maps have been designed in accordance with all applicable
established environmental standards and do not require any variances from these
standards. Detailed noise studies have been completed for each of the proposed
tentative tract maps by the firm of Mestre Greve Associates. These studies show all
of the proposed projects can be buffered from noise impacts to comply with the City
of Carlsbad's Noise Policy. The projects have been designed in compliance with the
recommendations of these reports and are in compliance with the City of Carlsbad's
Noise Policy. Copies of the noise reports for the individual tentative tract maps are
attached.
16) The proposed project is being implemented as part of the Calavera Hills Master
Plan. That plan established certain development standards and procedures that each
Village must comply with as it develops. The project also is being carried out in
accordance with the conditions of the Zone 7 LFMP, which is part of the City's
overall general plan.The proposed project will consist of six tentative maps that will
complete the development of the residential portion of the Calavera Hills Master
Plan. The impacts of the development of this area were addressed by the previously
certified EIR-403.
.
17) A permit will be required from the California Department of Fish & Game for the
elimination of the riparian scrub area adjacent to Elm Avenue in Village H. This
requirement is discussed in sections 10 & 11 of this document and the Biological
Study that is attached.
18) The project does not propose any uses requiring a conditional use permit. Site plans
and tentative map will conform to zoning requirements, negating the need for
variances.
19) The residential land use envisioned will not involve the use of hazardous materials.
Standard construction materials will be used. Potentially hazardous materials are not
known to exist in the area and have not been found in other areas of Calavera Hills.
20) The proposed project will not involve construction of facilities in a floodplain. The
subject property is not located near any creeks or rivers.
21) The proposed project is not located in an area of an active fault. The nearest fault
is approximately 7 1/2 miles west of the property, which is the Rose Canyon Fault.
22) While under construction, the proposed project will generate typical amounts of dust.
The City will require that the site be watered before and during grading operations
to control the amount of dust created by the proposed development. Grading will
have to comply with SDAPCD and CARB standards and requirements in Title 24
of the California Administrative Code to control dust and emissions. After
construction, there will be no significant amounts of dust generated from the new
residential subdivisions.
23) Vegetation will be removed from the property for preparation for building--however,
the vegetation is not anticipated to be burned, rather it will be scraped off and
hauled away.
24) The proposed project will result in incremental changes to the region's air quality
and the water quality of Aqua Hedionda Lagoon.
However, Carlsbad is in compliance with regional air quality standards because the
City's Land Use and Circulation Elements are included in SANDAG projections
which then become part of the San Diego Air Pollution Control District's projections.
Because this proposed project is in compliance with the general plan, it therefore
meets regional projections which anticipate incremental changes. Incremental
changes are not considered significant.
The water quality of Aqua Hedionda Lagoon has been incrementally impacted for
years by continuing upstream development in Calavera Hills and other areas within
the watershed. The drainage and erosion control devices required for these projects
will reduce their impact to a level of insignificance.
.
25) The project will incrementally increase fuel consumption during construction. When
completed, a residential subdivision will not consume significant amounts of fuel.
San Diego Gas & Electric Company is able to supply natural gas and electricity to
new housing projects throughout San Diego County.
26) The project proposes some development on 25% and greater slopes. This occurs in
Villages H,K,L-2,U,W, and X, and involves approximately 25.8 acres. This represents
approximately 13.7% of the area that will actually be graded by these tentative maps.
This figure of 25.8 acres is only 8.9% of the total area included within the boundaries
of Villages H,L-2,R,U,W,X and Y. In addition over 75% of the existing slopes in
excess of 25% within these villages will be preserved. A substantial portion of this
encroachment is created by College Boulevard and other roads need to provide
access to these villages. The chart below breaks down the amount of encroachment
into 25% slopes by each village.

27) There will be a significant change to existing landform with grading amounts of more
than one million to create roads and building pads on the existing hilly terrain to
achieve acceptable engineering standards. Much of this grading will be necessitated
by the construction of Elm Avenue and College Avenue two Circulation Element
Roadways. The rocky terrain of the undeveloped portion of the Calavera Hills
Master Plan, makes it infeasible to develop projects that are not sensitive to the
existing terrain. The amount of grading proposed for these tentative maps is 7864
per acre, which is in conformance with the requirements of the City of Carlsbad's
Hillside Development Ordinance. The following paragraphs explain how the grading
for this project complies with the City of Carlsbad's Hillside Development Ordinance.
Alterations to existing land form, resulting from the proposed development, may
appear significant unless viewed within the context of the overall project. Several
measures have been incorporated within the project's design to insure that grading
associated impacts will be minimized to the extent feasible.
First, project grading has been designed to balance onsite, thus eliminating impacts
normally associated with in import/export grading operation. It is important to note
that, due to the wide variation in topographic conditions between villages, this
balance may require that more than one village be included in each grading phase.
.
Additionally, over one half of the project site's 290.4 total acres will be retained as
undeveloped open space. Grading for the project will require a total cut of 1,165,147
cubic yards and a total fill of 1,286,907 cubic yards confined to an area of
approximately 159 acres which includes both onsite (approximately 152 acres) and
offsite (approximately 6.8 acres) improvements.
A "gross" grading ratio of 8094 cubic yards/acre results when the high volume of fill
is divided by the area of grading activity. A "net" ratio of 7097 cubic yards/acre is
achieved when the grading directly associated with the construction of College
Boulevard (both on- and off site: 208,142 cubic yards fill) is deducted from the
project grading totals. Following the exclusion of this circulation element roadway,
the grading ratio for the remaining villages of Calavera Heights falls within the
Hillside Development Ordinance's "acceptable" range of less than 8000 cubic
yards/acres.
Within the remainder Villages of Calavera Hills, there are three areas that involve
the construction of slopes over 30 feet in height. Those areas are located on offsite
College Blvd., within Village L-2 and Village K. Approximately 600 feet south of
the Village X boundary exists a fill slope of approximately 60 feet. This slope is
associated with the grading necessary to construct College Blvd. which is a major
Circulation Element roadway. Within L-2 a fill slope located between an existing
water tank and Cay Drive is approximately 50 feet in height. This graded slope is
due to the existence of a public utility and an existing public right-of-way (Cay
Drive). Finally, within Village K a fill slope exists west of Glasgow Drive. The
developed area (K-3) is constructed on all sides by existing constructed public right-
of-ways which restrict pad elevations and project access points. Additionally, to meet
City intersection spacing requirements, the project entry is at street 'X' which
necessitates grading into the area requiring the 45 feet of fill slope.
28) The proposed project, as part of the City's Growth Management Program, will not
substantially impact utilities, sewers, or streets because the project will provide its
share of improvements so that acceptable performance standards are maintained.
For example, there are special conditions in Zone 7 which pertain to drainage,
circulation, and sewer facilities which must be adhered to prior to developing any of
the Villages in Zone 7.
29) Soil erosion will not increase significantly as a result of the proposed project.
Maintenance of all manufactured slopes will be with standard erosion control
techniques. Permanent landscaping will be established as quickly as possible on
common areas as well as private yards. During the construction, standard erosion
control facilities will be installed to reduce the amount of erosion to a level of
insignificance.
30) Wildlife habitat has been discussed in question #s 10 & 11 and the attached
Biological assessment for this project.
S .
31) New light will be produced by streetlights and house lights in the new subdivisions.
The streetlights will be conformance with the City's standards. The proposed project
is located in an urbanizing area, and will introduce new light into a previously
darkened part of the city. The project specific impacts of light and glare from
streetlights,houselights and vehicles can be lessened to a level of insignificance.
These projects will, in conjunction with other past, present and future projects
contribute to light and glare created by all developments occurring in this portion
of the City. Lighting installed for these projects will be in conformance with all
applicable City standards.

INTRODUCTION AND BACKGROUND
This ETA addresses the proposed tentative tract maps for the remaining residential in the
Calavera Hills Master Plan. The applicant Lyon Communities Inc. is submitting 6 tentative
tract maps that will cover Villages H,K,L-2,R,U,W,X, and Y. The individual tentative tract
maps are described below. For additional details see the chart below and the tentative
maps.

In 1978 the City of Carlsbad certified an EW for the entire Calavera Hills Master Plan.
This Effi was based on a maximum development of 3452 dwelling units and 10 acres of
commercial. Since that time approximately 1000 dwelling units have been constructed in the
Master Plan area. Also a number of changes have been made to City ordinances and
policies that have resulted in substantially less dwelling units and more open space in the
Calavera Hills Master Plan. At this time the maximum number of dwelling units that can
be occupied is 2333 and there will be at least 10 acres of commercial in the Master Plan.
All of the proposed development will be occurring in portions of the Master Plan that were
designated for development by the original Calavera Hills Master Plan that was addressed
by Effi 403 that was previously certified by the City Of Carlsbad. The proposed projects
will gain access from existing and future arterial roadways that were addressed by the
. .
previously certified EW. The proposed developments will not alter these roadways or
create any new Circulation Element Roadways. These Circulation Element Roadways will
allow construction traffic to access the developable areas without driving through existing
residential areas or using local streets. This will serve to minimize the impact on the
existing residents of the Master Plan.
Attached to this ETA are the following updated studies that are in compliance with current
standards:
Biology
Archeology
Noise
Soils
Traffic
The Biological and Archeological studies also address the offsite impacts created by the
extension of College Boulevard from the southerly edge of the Master Plan to the future
alignment of Cannon Road. This alignment will follow the alignment of College Avenue
as shown on the Circulation Element of the Carlsbad General Plan. Construction of this
portion of College Avenue will have minimal environmental impacts since the vast majority
of this portion of the College Avenue alignment has been under agriculture for a number
of years.
Traffic and other public facilities were addressed in the Local Facilities Management Plan
for Zone 7. This plan addressed the impacts of existing and future development in the
Calavera Hills Master Plan. The tentative maps that are being addressed by this ETA
represent the remaining development in Zone 7 except for the 10 acre commercial site.
The traffic impacts created by future development in Zone 7 will be created by these
projects. The developer of these projects will be responsible for implementing the traffic
mitigation measures and improvements called out for in the Zone 7 Local Facilities
Management Plan. A copy of the Circulation section of the Zone 7 Local Facilities
Management Plan and the traffic studies used to prepare that section of the plan are
attached to this study.
The purpose of this ETA is to show that the impact of the proposed development which is
in compliance with the approved Master Plan, will not create any impacts that were not
addressed by the previously certified Effi. The updated studies and information in this ETA
addresses new ordinances and policies that have come into existence since the original
Effi was certified. After a careful review of the original Effi, the updated studies and the
information in this ETA the applicant believes it will be possible for the City to issue a
Mitigated Negative Declaration for these projects. The information and recommendations
in the studies and this ETA will provide the information that staff needs to write the
conditions for the Mitigated Negative Declaration.
