INTRODUCTION
Recent California legislation (AB 3180) requires the adoption of a mitigation
measure/monitoring and reporting program in conjunction with approval of pro-
jects for which a final subsequent EIR was prepared and mitigation measures were
recommended - action with significant impacts.
The purpose of the law is to establish a reporting and monitoring program to
assure implementation of recommended mitigation measures.
The following monitoring program is recommended as part of the South Poway
Planned Community: CalMat-Poway Subsequent EIR {May 1990}. The subsequent EIR
discusses the reclamation plan and aggregate extraction on the approximately
166-acre site located north of Beeler Canyon Road and south of Kirkham Road in
the South Poway area. This proposal involves Reclamation Plan 89-05 and
Conditional Use Permit 89-05. The following excerpts from the subsequent EIR
address the mitigation monitoring and reporting program for seven types of
impacts along with the analysis of significance. The seven impacts addressed
are: Biological resources, land use, aesthetics/landform alteration, traffic,
noise, air quality, and utilities. A complete discussion of the potentially
significant environmental impacts and mitigation measures for each topic is con-
tained within Section 4 Environmental Analysis of the subsequent EIR.

RESOURCES
MITIGATION MONITORING AND REPORTING PROGRAM
References in the following monitoring requirements apply to the same numerical
designations in the mitigation section above.
1) The spring survey would be included as a condition of the CUP.
2)
The CUP will depict an open space easement over the riparian habitat. During
the annual review of the CUP, a biologist will confirm that no disturbance has
occurred to the wetland resources.
3)
Approval of the restoration plan will incorporate provisions of the coastal sage
scrub vegetation and monitoring program.
4)
Partial mitigation for the southern California grassland would include off-site
acquisition of e.,fisting high.quality grassland or degraded grassland which could be
enhanced.
5)
Payment toward the California gnatcatcher study and or acquisition funding will
be made a condition on the CUP.
ANALYSIS OF SIGNIFICANCE
propoxcd. The mitigation measures proposed by the applicant do not reduce the
significant adverse biological resource.impacts to a level below significance.
4.2 LAND USE

Page 7
MITIGATION MONITORING AND REPORTING PROGRAM
Closing Bcclcr Canyon Road to all heavy truck traffic entering and leaving the CalMat -
Poway operation by providing an internal'road with access via Kit 'kham Road within one
ye-ar two years of approval of expansion would be a condition of approval for the
Conditional Use Permit.
ANALYSIS OF SIGNIFICANCE
The proposed project is substantially in conformance with the General Plan and the
South Poway Plam~cd Community regulations and no significant land use impacts have
been identified. Regarding adjacent land use impacts, significant impacts would be
mitigated to a level below significance with the rerouting of heavy truck traffic on a
private access roadway built to public road standards with access via Irdrkham Road and
with the barring of all heavy truck traffic on Beeler Canyon Road.
Resolution Ilo. 90-163
4.3 AESTHETICS/LANDFORM Page 8
ALTERATION
MITIGATION MONITORING AND REPORTING PROGRAM
City staff would review and City Council would approve a revised Reclamation Plan for
the CalMat - Poway site concurrent with thc approval of thc Conditional Use Permit.
The revised Reclamation Plan would be monitored annually to ensure on-going
revcgctation and reclamation are in conformance with the approved Reclamation Plan.
AN,~kL,YSIS OF SIGNIFICANCE
There arc significant impacts associated with thc landform alteration of the 166-acre
CalMat - Poway site. Because thc topography range is prominent and currently vacant
and because the extraction process necessitates removal of the landform, impacts to the
landform of thc proposed project are considered to be significant. An environmentally
sensitive Reclamation Plan which includes a phased or concurrent rcvegetation and
reclamation process would, however, reduce the significance of these impacts but not to
below a level of significance. As indicated previously, overriding considerations would
be required.
4.4 TRAFFIC
Resolution Iqo. 90-163
Page 9
MITIGATION MONITORING AND REPORTING PROGRAM
Completion of an access road built tO public road standards to carry truck traffic in/out
of the proposed project site to thc north within two years of project approval would be
a condition of thc Conditional Usc Permit.
ANALYSIS OF SIGNIFICANCE
The proposed project expects to generate approximately 886 daily trips by heavy trucks
for a worst case scenario. With completion of an internal road to handle heavy truck
traffic, impacts relating to traffic generated by the expanded plant operation would be
considered at a level below significance.
In the long term, most of the streets in the project vicinity will operate at LOS D or
better, which is a goal for the City of Poway for long range plamzing. Some sections of
Poway Road and Pomcrado Road will operate at less than desirable levels of service.
Under short term conditions, the intersection of Poway Road with Pomerado Road is
expected to operate at LOS D, which is a lcss than desirable level of service. Since.thc
opening of thc South Poway Parkway (Alternative SA) is expected to change the regional
traffic patterns in thc area, thc LOS for this intersection, under long term conditions, was
not calculated. Thc increase in traffic generated by CalMat - Poway is not significant
on a project-level; however, it does contribute incrementally to an already congested
condition.
Resolution No. ~0-163
4.5 NOISE Page 10 ;
MITIGATION MONITORING AND REPORTING PROGRAM
Potentially significant noise impacts associated with normal operation of the facility have
been identified. However, an additional acoustical analysis will be performed to
determine exact sources and levels of noise, based on specific layout and design of thc
expanded processing plant site. Once this analysis has been performed, a comprehensive
monitoring and reporting program can be implemented by a Mitigation Monitoring
Coordinator who will ensure that proper, normal operating hours and appropriate noise
lcvcls mcct all city rcquircmcnts. Periodic monitoring will be conducted by tile
Coordinator.
As a condition of approval of the CUP, a detailed acoustical report will be required to
determine thc size o£ tile acoustical barrier (i.e., berm and wall). It is anticipated that
up to a ten foot barrier will be required. The exact siting m~d height will be identified
in tile acoustical study.
ANALYSIS OF SIGNIFICANCE
If tile mitigation measures suggested in the acoustical report (siting of machinery and
stockpiles, construction of a noise barrier, and using flashing strobes during twilight hours
and night usc of equipment back-up alarms) and in this document arc implemented as
conditions of thc CUP, then potential noise impacts would be mitigated to a level below
significance.
4.6 AIR QUALITY Reso'lut'ior, Ho. ~0-163
Page 11
MITIGATION MONITORING AND REPORTING PROGILAM
Although thc City of Poway is thc lead agency for thc proposed project, responsibility
for aggressively pursuing an active monitoring and reporting program would rest with
cooperation of the facility operators and thc San Diego APED.
Numcrous alternatives exist to monitor compliance of thc operation of thc facility. To
a large degree thc permitting process establishes some form of controls and reporting
means. A qualified APCD staff member would conduct site inspections during initial
implementation of the proposed expansion. Eka-m-cottectcd--at--the-cto~e~t-monitohng

,~'uNALYSIS OF SIGNIFICANCE
Though some unavoidable, adverse impacts are associated with the operation o£ this type
of facility, no significant impacts can be expected with respect to basin air quality, if the
above mentioned nfitigation recommendations are fully and actively implemented.
UTILITIES Resolution No. 90-163
Page 12
MITIGATION MONITORING AND REPORTING
Water
To ensure that impacts to water quality and quantity arc reduced to levels below
significance, RWQCB will specify a formal monitoring and reporting program as
conditions to issuance of a Waste Discharge permit. Water quality monitoring and
reporting will be required, as well as technical reports concerning the quantity and quality
of any waste discharge, to assure RWQCB requirements have been met. The City will
review thc report as a part of their annual review of the Conditional Use Permit (CUP).
No significant impacts were identified. Should CalMat choose to utilize natural gas,
written notification from SDG&E stating thai adequate itffrastructure is available to
service the needs of the CalMat-Poway facility must be made prior to approval of CUP.
ANALYSIS OF SIGNIFICANCE
Water
Impacts to water supply can be mitigated to below a level of significance by
incorporation of the above mentioned mitigation program.
Eneri..W.
Thc lack of adequate infrastructure to service thc cncrgy demands of thc proposed
expansion project is.considered to be a significant but mitigable impact. Provision of
right-of-way casements and a gas line with the capacity to transport 12 million BTU/hr
of fuel would mitigate these impacts to a level below significance should thc usc of
propane or alternative fuel source not be used.
The expansion o£ the facility to increase the amount of aggregate to be mined and to
add thc asphaltic concrete projection element would contribute to the increased use of
non-retrievable natural resources.

CANDIDATE FINDINGS
FOR THE
CALMAT- POWAY
FINAL SEIR
Resolution No. 90-163
Page 14
The following findings are made relative to the conclusions of the Final Environmental
Impact Report (EIR) for the CalMat-Poway project. The project involves the expansion
of the current operation from 83 acres to a total of 166 acres. CalMat proposes to
construct a private access road to divert truck traffic from Beeler Canyon and Creek
roads per recommended mitigation for expansion of aggregate extraction in the South
Poway Planned Community EIR. Through negotiations with City staff in the winter of
1989-90, CalMat agreed to construct the access road to public road standards as part of
the expansion project. The expanded site will contain primary and secondary processing
facilities which allow production of a full range of construction aggregate, road base and
fill material. A ready-mixed concrete batch plant will continue operations, along with an
asphaltic concrete and cement-treated base plant. To expand the site, the City of Poway
will need to approve a Conditional Use Permit because CalMat's Special Use Permit
P73-130M3W issued by the County of San Diego, prior to the City of Poway's
incorporation will expire in October 1991; as well as approval of the Reclamation Plan.
These findings are made pursuant to Section 21081 of the California Public Resources
Code and Sections 15091 and 15092 of the California Administrative Code.
FINDINGS
mo
The City of Poway, as lead agency and decision maker, having reviewed and
considered the information contained in the Final EIR for the project and the
public record, finds, pursuant to CEQA and CEQA State Guidelines, that changes
or alterations have been required in, or incorporated into, the project which avoid
or substantially lessen the significant environmental effect as identified in the Final
EIR with respect to the areas of (1) biological resources, (2) land use, (3)
aesthetics/landform alteration, (4) traffic, (5) noise, (6) air quality, and (7) utilities.
Specifically, the City of Poway makes the following findings with respect to the identified
significant environmental effects of the project:
With respect to biological resources (EIR, pg. 4-1), the proposed project
involves the expected loss of all of the site's breeding California
gnatcatchers (a minimum of four pair), all of the sensitive Diegan coastal
sage scrub (71 acres), Southern California grassland (10 acres), chamise
chaparral (8 acres), and the combined loss of all the site's other sensitive
species. These losses would be considered regionally significant adverse
impacts of the proposed project both individually and in a cumulative sense.
There are feasible mitigation measures which would reduce impacts to
below a level of significance; however, the applicant has determined that
Resolution No. 90-163
Page 15
these measures are not feasible. The following mitigation measures are
incorporated into the project but do not reduce biological resources impacts
to below a level of significance. Overriding considerations per the
California Environmental Quality Act (CEQA) would need to be developed
for the City Council action in the event the City Council approved a
project. The following mitigation measures should be incorporated into the
resolution for the project.
a. A "spring survey" would be conducted in April through June to
assess the status and distribution of the following sensitive species
which are potentially present on-site: San Diego thorn-mint, Orcutt's
brodiaea, San Diego goldenstar, California adder's-tongue fern, and
variegated dudleya. All but the last of these would occur in the
Southern California grassland or adjacent areas. Variegated dudleya
could occur in dry diegan coastal sage scrub habitat. These are
significant species, and the presence of any of these in substantial
numbers would constitute a regionally important biological resource
of this site, requiring mitigation through a supplement to this
subsequent EIR. No disturbance of the spring time survey site shall
be allowed until completion of the survey and further environmental
review, if any.
b. Impacts to the on-site riparian scrub habitat would be avoided by
all grading operations. An open space easement would be designated
on the CUP. If inadvertent impacts occur, there would be mitigation
on-site through the development of a wetland mitigation plan. Such
a plan should require full mitigation of wetland losses which result
from implementation of this project. Such a plan would be prepared
by a qualified biologist familiar with such programs, working in
concert with a revegetation specialist or certified landscape architect.
A five-year monitoring program would also be required.
c. Impacts to on-site diegan coastal sage scrub vegetation would be
partially mitigated by the development of a diegan coastal sage
Scrub Habitat Restoration Plan, using manufactured slopes areas
which would be prepared for this purpose following the completion
of extraction activities. This will be incorporated into the restoration
plan. Additionally, to ensure success there should be long term
biological monitoring, including the preparation of status reports to
be reviewed by the City annually for a minimum of ten years. Such
a plan should be prepared by a qualified biologist familiar with such
programs, working in concert with a revegetation specialist or
certified landscape architect.
d. Off-site mitigation to partially compensate for the loss of the site's
Southern California Grassland could be developed in the form of
habitat restoration and/or enhancement. This would require the
2
Resolution No. 90-163
Page 16
eo
identification of target areas, suitable for the establishment or
restoration of a diverse native grassland. South Poway still contains
several large areas of grassland habitat which could be augmented
and/or upgraded through the development of a native grassland
restoration project. The specifics of such a plan are beyond the
scope of the biological report prepared for the EIR; however, it
would require, at a minimum (a) off-site restoration or enhancement
area identification; (b) the preparation of a precise planting program,
specifying species and quantities to be used (based on indigenous taxa
and diversity ratios); (c) possible specimen, soil and/or inoculum
salvaging from the existing grassland; (d) a complete soil preparation
plan; (e) maintenance, including irrigation requirements, the control
of exotic annuals, etc; and .(f) long-term biological monitoring,
including the preparation of status reports to be reviewed by the City
annually for a minimum of five years. Such a plan should be
prepared by a qualified biologist familiar with such programs, working
in concert with a revegetation specialist or certified landscape
architect.
The City of Poway is currently conducting a California gnatcatcher
study. The goal of this study is to provide direction to the City as
to the appropriate measures necessary for the preservation and
enhancement of gnatcatcher habitat. CalMat should contribute
financially for the acquisition of lands targeted by the study for
preservation. This mitigation measure would be a condition of the
CUP. The amount of financial contribution will be determined by
the City staff. Funds contributed will be specifically used for the
acquisition of land for enhancement or preservation of gnatcatcher
habitat.
With respect to land u~e (EIR, pg. 4-15), the proposed project involves the
use of the site to mine aggregate in keeping with the Mineral Resource
Zone-2 (MRZ-2) for aggregate by the State of California Department of
Conservation, Division of Mines and Geology. The project is generally in
conformance with the extraction goals of the South Poway Planned
Community regulations and no significant land use impacts have been
identified. Regarding adjacent land use impacts, significant impacts would
be mitigated to a level below significance with the incorporation of the
following measure:
ao
Closing Beeler Canyon Road to all heavy truck traffic entering and
leaving the CalMat-Poway operation by providing an internal road
built to public road standards with access via Kirkham Road within
15 months of approval of expansion plans. This measure will be a
condition of approval of the CUP.
Resolution No. 90-163
Page 17
o
With respect to aesthetics/landform alteration (EIR, 4-22), the proposed
project involves excavation of the entire approximately 166-acre site. The
final landform will include an 88-acre pad at the base of the aligned slopes,
a maximum 2:1 slope of approximately 300 feet, and several flat pads at the
top of the slopes. Because the topography range is prominent and currently
vacant and because the extraction process results in removal of the
landform, impacts to the landform of the proposed project are considered
significant. The following mitigation measures have been recommended to
reduce impacts but not to below a level of significance (Overriding
considerations per CEQA would be required):
ao
Concurrent reclamation restricting the disturbance area and
revegetating disturbed areas of the slopes before mining begins in
another area.
Co
do
Revegetation to include native and natural plant species which would
blend with existing vegetation.
Undulating the slopes following the original contours of the landform,
rather than one large pad.
Establish transition areas or buffer areas to blend the graded areas
with native areas.
Benching of slopes to ensure long-term stability and minimize slope
erosion.
On-site landscape screening of existing and proposed operations which
block views from nearby sensitive receptors.
With respect to traffic. (EIR, pg. 4-33), the proposed project would involve
the routing of heavy truck traffic (incoming and outgoing) onto a private
internal road built to public road standards. The total number of truck
trips associated with the project expansion is expected to be 886 trips.
Impacts relating to traffic generated by the expanded plant operation would
be considered at a level below significance; however, it does contribute
incrementally to an already congested regional condition. The following
measure has been incorporated into the project design which would reduce
impacts to below a level of significance.
Completion of an access road to carry truck traffic in/out of the
proposed project site to Kirkham Road within 15 months of project
approval would be a condition of the CUP.
With respect to noise (EIR, pg. 4-41), the project involves the increase in
noise levels resulting from operation of on-site equipment and truck traffic
along the internal access road. These potentially significant noise impacts
R~so'lution ho. ~,0-163
Page 18
o
would be reduced to a level below significance with the provision of the
following mitigation measures incorporated into the project design:
ao
Conduct an additional acoustical analysis to determine exact sources
and levels of noise, based upon specific layout and design of the
expanded processing plant site.
A detailed acoustical report be required as a condition of the CUP
to determine the location and height of acoustical barrier (i.e., berm
and wall) along the access road.
Co
All production operations shall be limited to the time period set in
the CUP.
do
The processing plant layout would be evaluated in terms of
maximizing the use of storage and surge piles to shield noisy
equipment such as secondary crushers and vibrating screens. In
addition, the secondary crusher would be sheltered in such a way as
to create a pit in which noise will be 'funneled upward instead of
radiating outward.
Back-up alarms on loaders, dozers, water trucks and other mobile
equipment would be turned off during twilight hours and replaced
with a flashing strobe as authorized by MSHA to minimize the
intrusive noise from such alarms.
With respect to air quality (EIR, pg. 4-47), the project involves the increase
in fugitive emissions (primarily dust) and traffic generated emissions. These
impacts are considered to be unavoidable adverse impacts associated with
the operation of an aggregate extraction and processing facility which can
be mitigated to below a level of significance. The following mitigation
measures have been incorporated into the project design and identified
which would reduce impacts to below a level of significance:
ao
Authority to construct and permits to operate must be obtained from
the San Diego APCD that satisfy the air district that all available
measures have been taken to minimize the project air quality impact.
bo
Annual monitoring of emissions will be done by the APCD to ensure
that the plant operates as designed.
c. Paving and daily wet sweeping would be required on the access road.
do
Conveying, screening and crushing operations will require adequate
water at transfer points for dust control.
Resolul:ion No. 90-163
Page 19
eo
Frequent watering of the haul routes will be required to limit dust
emissions from the equipment moving on unpaved in-plant surfaces.
An extensive planting program along the access road from the site
would include both a fast-growing shrub component such as oleander
as well as a dense row of trees to act as a windbreak, confining dust
and sand particles to within the site during Santa Ana wind
conditions from the east/northeast.
go
A baghouse will be required for the asphalt plant to control
particulate emissions as well as blue smoke control of hydrocarbon
vapors from the asphalt heater/drier and storage silos.
ho
Implementation of effective controls on process emissions using best
available technology to prevent the formation of any significant air
quality effects from normal plant operations.
Implementation of an aggressive housekeeping program to control
fugitive dust emissions (e.g., Runoff and Sedimentation Control Plan).
Re-routing haul traffic through industrial areas and along the
proposed new private access road, away from existing residential
developments.
With respect to utilities (EIR, pg. 4-63), the project involves the estimated
water requirement of approximately 381 acre-feet per year (1.66 acre-feet
per day) which was determined to be significant but mitigable to below a
level of significance. No significant impacts were identified for energy
consumption; therefore, no mitigation is required. The incorporation of the
following water conservation measures would reduce impacts to below a
level of significance.
A formal Runoff and Sedimentation Control plan be developed to
assure that excessive erosion and sedimentation would not occur
which could adversely affect Beeler Creek.
bo
A technical study be conducted to determine the maximum utilization
of reclaimed water for aggregate production.
Dual piping would be added to the project site upon expansion to
ensure facilities are in place once reclaimed water becomes available.
This would minimize potable water use. Reclaimed water would be
used for all mining operation and for on-site dust control.
do
Environmentally-safe surfactants are mixed with water used to spray
roads to control dust to maximize effectiveness and reduce water
consumption.
Resolution No. 9d-163
Page 20
Bo
Co
eo
Aggregate plant process water would be clarified by means of settling
ponds and recycled for continued use.
Rainfall runoff from the plant site would be directed into a
sedimentation pond so that it can be used for dust control purposes.
go
Mixer truck cleanout water would be directed into a sump for re-
use by the plant.
ho
The floor of the pit would be graded to direct water to an erosion
sump/containment basin at the lower end of the pit.
The City of Poway, as lead agency and decision maker, having reviewed and
considered the information contained in the final subsequent EIR for the project
and the public records, finds that there are changes or alterations to the project
which avoid or substantially lessen the significant environmental impacts,
specifically, implementation of the mitigation measures detailed above.
The City of Poway, as lead agency and decision maker, having reviewed and
considered the information contained in the final subsequent EIR for the project
and the public record, finds there are no specific economic, social, or other
considerations which make infeasible the mitigation measures in the EIR. With
regards to the project alternatives, several issues may render any part or all of
each alternative(s) infeasible for reasons included below:
With regards to the No Project Alternative, 'the on-going extractive and
processing operations at the present site (68 acres) would continue until
expiration of their SUP in October 1990 at which time all further quarrying
activities would end, and the site would be reclaimed in accordance with
the SUP. This alternative would eliminate the significant adverse
unmitigable impacts to biology and aesthetics/landform alteration. In
addition, significant but mitigable impacts to land use, traffic, noise, air
quality, and utilities would not occur. This alternative would have the
following additional impacts:
ao
Adoption of this alternative would not provide a local source of
aggregate for nearby construction, thus requiring construction projects
to travel greater distances to obtain this resource.
bo
Utilization of the present CalMat facility and the surrounding area
of enlarged extraction potential, as indicated in the South Poway
Planned Community Land Use Plan, and as set forth as partial
mitigation for the loss of regionally-significant mineral resources
resulting from industrial development, would not occur.
Resolution No. 90-163
Page 21
o
This alternative would also not meet the following objective;
maximize the recovery of the on-site regionally-significant mineral
resource.
With regards to the Limited-Scale Alternatives there are two scenarios
including 1) continued operation within the existing boundaries with no
additional uses, and 2) expanded extraction operations into the 166 total
acres without an asphaltic plant on-site.
Scenario one (1) would reduce the magnitude of impacts to biology and
aesthetics/landform alteration. This alternative would result in an
incremental reduction in impacts to noise, air quality and utilities.
This alternative would not meet the objectives of CalMat for the following
reasons:
This alternative would not meet the project's objectives of providing
processing facilities for asphaltic concrete and expansion to include
the additional 83 acres.
The adoption of this alternative does not meet the intent of the
partial mitigation requirement for the loss of regionally-significant
mineral resources resulting from industrial development.
Scenario two (2) would result in an incremental reduction in air quality
impacts as a result of no asphaltic concrete plant. 'Impacts to land use,
traffic, noise and utilities would be similar to the proposed project. Impacts
to biology and aesthetics/land form alteration would be adverse and
unmitigable.
This alternative would not meet the objectives of CalMat for the following
reasons:
a. This alternative does not significantly reduce the level of impacts.
This alternative would not meet the project's objective of providing
processing facilities for asphaltic concrete.
With respect to Alternative Siting. three sites were evaluated.
alternative sites would have the following additional impacts:
These
This alternative would not meet the following objectives of the
proposed project:
Extend the existing SUP as a CUP so that CalMat-Poway could
continue extraction in the South Poway Planned Community.
Resolution No. 90-163
Page 22
Provide for the expansion of the site as partial mitigation for
the loss of this mineral resource made unavailable by the
development of the Pomerado Business Park.
The increased hauling distance and cost of these sites would
make it economically infeasible to serve CalMat-Poway's 1-15
corridor marketing area which extends from the Kearny Mesa
area to Escondido.
With respect to Alternative Use-Residential Development, this alternative
would allow for reclamation of the site upon expiration of SUP in October
1990 to be developed as a low density residential community. The site
would experience typical air quality, biological, land use, traffic, noise,
aesthetics/landform alteration, and utilities/public services impacts associated
with residential use.
