Attached is the Growth Management Oversight Commission's 1990 Report which is scheduled
to be reviewed on July 25, 1991, at 4:00 p.m.
This meeting will give the GMOC an opportunity to discuss their review of the City's
compliance with the Quality of Life Threshold Standards for 1990 with the City Council.
RECOMMENDATION: That Council accept the 1990 GMOC Report and direct staff to docket
the required resolutions and ordinance amendments to implement the recommendations.
BOARDS/COMMISSIONS RECOMMENDATION:
The Planning Commission, on July 10, 1991, voted 4-0 to accept the 1990 GMOC Report as
recommended with the addition of a Visual Impact Threshold Standard.
The Montgomery Planning Committee, on July 10, 1991, voted 5-0 to accept the 1990 GMOC
Report with the addition of a Visual Impact Threshold Standard.
DISCUSSION:
The GMOC approved their 1990 Report and recommended Statements of Concern regarding
schools, water and air quality on June 27, 1991. On July 10, 1991, the Planning Commission
and Montgomery Planning Committee met in joint session with the GMOC. The Planning
Commission and Montgomery Planning Committee voted to accept the 1990 GMOC Report and
to recommend that the GMOC give consideration to adding a Visual Impact Threshold to the
Threshold Standards Policy next year. The concern is the increasing amount of visual pollution
occurring from graffiti, trash, cluttered drainage channels, erosion of banks, and animal
sediment in various parts of the City.
Staff will review the City's current programs regarding visual pollution with the GMOC during
the next review period and include a recommendation for the Planning Commission,
Montgomery Planning Committee and City Council consideration.
1-1
~-4-.
Page 2, Item ~
Meeting Date 75i
The other major concerns of the Planning Commission and the Montgomery Planning Committee
were how to increase the number of parks on the west side of the City and the continuing
problem of overcrowded schools.
The GMOC continues to be uncomfortable with its role regarding the Economic Threshold. The
economic monitoring function of GMOC should be shifted to the newly created Economic
Development Commission. The Economic/Fiscal Threshold would be renamed Fiscal Impact
Threshold Standard and would deal solely with the fiscal impacts of growth, including reports
on collection and expenditure of development impact fees. If Council concurs, an amendment
to the Economic Threshold Standard could be included in the implementation of the 1990 GMOC
Report.
The ordinance adopted by Council on May 7, 1991 (No. 2447) changing the GMOC to a
Commission technically terminated the existing members' term of office as of June 30, 1991.
Council will need to appoint 8 members to the Growth Management Oversight Commission prior
to the start of the next annual review in October, 1991.
The next annual review will change the review period from a calendar year to a fiscal year basis.
As such, the next GMOC review will need to start sometime in October, 1991. This will enable
the GMOC to complete its report and recommendations prior to City budget adoption. It also
will enable the GMOC to review data from various City departments and other public agencies
on a fiscal year basis which is the normal time period for local government operational reports.
FISCAL RdPACT: None. Future implementing actions will contain additional fiscal impact
review.

TO: The Honorable Mayor and City Council
FROM: Growth Management Oversight Commission
SUBJECT: 1990 GMOC Report
The GMOC ;s pleased to present its 1990 Report to the Mayor and City Council.
In many respects, 1990 was a significant year with respect to the City's
growth and development. The GMOC was very pleased with the Council's strong
leadership in adopting the first Growth Management Program and Ordinance for
the City of Chul a Vi sta. We bel ieve thi s program is an excellent step in
defining the prerequisites for the City's future growth.
We also acknowledge the preparation of the first mid-range Development
Forecast by the Planning Department which is now being used by City
departments and outside ,agencies in preparing their Threshold Status Reports
for GMOC. These forecasts will help all of us plan for the future rather than
simply letting it happen with unexpected consequences. .
Other noteworthy events wh i ch occurred inca 1 endar year 1990 are further
detailed in the 1990 GMOC Report. Highlights of the report include:
1. The City is in compliance with the following threshold standards:
Police
Fire and Emergency Medical Services
Parks and Recreation
Sewer
Drainage
Traffic
Economic/Fiscal
libraries
2. GMOC recommends that the City Council issue Statements of Concern
for the following threshold standards:
Air Quality
Schools
Water
3. GMOC repeats our recommendat i on from 1 ast year to amend the Parks
and Recreation Threshold.
4. GMOC is recommending changing the Traffic Threshold Standard from
the Intersection Capacity Utilization method to the 1985 Highway
Capacity Manual method.

During 'the course of preparing the 1990 Report, the GMOC met ten (10) times
from February 14 to June 27, 1991. As a general observation, we found the
written reports submitted for evaluation of thresholds which are the sole
concern of the City (i.e., police, fire, economics, libraries, sewer,
drainage, traffic and parks and recreation) were timely and adequate. The
information prepared by staff on the City Recycling Program was very good.
The report from Park and Recreation staff was equally as good and very
complete.
The GMOC is concerned that the reserve sewage capacity in the San Diego Metro
system set aside for Chula Vista may not be available when we need it in the
future. We have asked the Engineering staff to help us obtain information on
this concern fro. the City of San Diego.
In the course of our deliberations, the Commission continues to be concerned
about the deficiencies in park acreage on the west side of the City. We are
repeating our recommendations from last year's report with respect to changing
the parks and recreation threshold since no action has been taken as of this
date. Innovative steps need to be taken to alleviate the serious shortage of
park lands in the older part of the City.
The traffic threshold standard is proposed to be improved. The GMOC has
learned that the 1985 Highway Capacity Manual (HCM) method of measuring
traffic congestion is less theoretical and more empirically based than the
Intersection Capacity Utilization method. We have included in our report a
recommended traffic threshold standard based on the 1985 HCM method together
with a complete report discussing the recommended change.
The annual fiscal/economic report provided by the fiscal consultant was beyond
the oversight level of our review. We suggest that staff consider using the
fiscal/economic data used in preparing the City's annual budget for our
threshold review next year. We also noted in our report that the sales tax
revenue per capita in Chu1a Vista continues to be near the bottom of cities in
the County. We need to stress economic development in order to continue city
services at optimum levels.
We were most happy to learn of the City's success in obtaining the $6.85
million grant .from the State Library Bond Program to build the Montgomery
Library. This library was desperately needed by citizens in the Montgomery
community and will certainly enrich the quality of life in the community.
The GHOC noted that the information provided to us by the San Diego County Air
Pollution Control District (APCD) was much improved from last year. We would
still like to receive information on industrial pollution and enforcement
actions by APCD on industries in Chula Vista. We are hoping for better
information from APCD in the future.
The GHOC noted the improved coordination between the City and the
districts with the creation of the Inter-Agency Water Task Force.
promises to improve the exchange of vital information between all
entities to better address our long range water needs.

The situation with school overcrowding still requires further improvement.
The Chula Vista Elementary District is taking steps to more forcefully
articulate the position of the District regarding funding of new facil ities.
Clearly there is a continuing need for action at the policy level to address
the faCility needs of our school district.
In conclusion, GHOC wishes to comp1 iment the staff from all departments and
agencies who provided support during our review process. They were extremely
helpful and made our task more enjoyable and productive.

GROWTH MANAGEMENT OVERSIGHT COMMISSION
1990 REPORT
CITY OF CHULA VISTA
INTRODUCTION
In November 1987, the City Council adopted the Threshold/Standards Policy for
Chula Vista. Eleven issues are addressed in the Policy Statement and are
discussed in terms of a goal, objectives, threshold or standard, and an
implementation measure. Adherence to these Citywide Standards is intended to
preserve and enhance the public services, environment, and quality of life of
Chula Vista residents.
To provide an independent annual City-wide threshold review, a Growth
Management Oversight Committee (GMOC) was created. The Committee was
appointed by the City Council in the summer of 1988. It is composed of nine
members with geographical balance as well as a .cross section of interest
including educational development, environmental interest, and business
interest. There is also representation by the Planning Commission. In April
of 1991, the Counc i 1 changed the des i gnat i on of the Commi ttee to the Growth
Management Oversight Commission.
The responsibilities of the Commission include the following: a determination
as to whether each threshold is appropri ate for its goal, whether any new
thresholds should be adopted for any issues, whether any new issues should be
added or deleted to the threshold group, whether or not comp 1 i ance wi th the
thresholds has been maintained over the prior year, whether compliance is
likely to be maintained based on both short term and long-term development
forecasts, what the fiscal impact of compliance may be, whether the City has
been us i ng developer fees for the intended purpose, and whether the means of
achieving compliance are appropriate.
In April 1991, the Council incorporated the threshold standards into the
Growth Management Program and Implementation Ordinance. Future development
projects in Chula Vista will include measures to assure that the threshold
standards are maintained as growth occurs. This "concurrency" policy will
promote the continuation of a high quality of life for existing as well as new
city res i dents.
The GMOC also reviewed the recommendations of the Resource Conservation
Commission regarding the need to improve the measurability of the threshold
standards. It was acknowledged that measurable threshold standards were
desirable and the GMOC continues to make improvements to these standards each
year. For example, last year, the traffic, park and recreation and
economic/fiscal threshold standards were reviewed and improved. The threshold
standards for Civic Facilities, Corporation Yard, and Schools will be
addressed during the next annual review.
PROCESS
The Threshol d Pol icy calls for the Growth Management Overs ight Commi ss i on to
meet at the beginning of each calendar year. The first several meetings were
spent reviewing the threshold policies and determining compliance with those
2-1
GMOC REPORT

policies based on reports that were received from individual departments and
agencies. Background information and presentations were made by
representatives of the three water districts, both school districts, San Diego
County Air Pollution Control District and City staff including Engineering,
Traffic Engineering, Parks and Recreation, Library, Fire, Police, Fiscal,
Administrative and Planning. As each issue was reviewed, the GMOC determined
whether or not it was appropri ate to issue a statement of concern or take
other action regarding that issue. Following the completion of the individual
threshold reviews, this annual report was prepared, and adopted by the
Commission.
The next annual review is proposed to begin in the fall of 1991 so that the
GMOC report can be completed by March 1992. The original policy called for an
annual review and the first three reports have been based on a calendar year.
However, as the GMOC work' has grown in volume and soph i st i cat ion, the time
required to carry out the review has generally taken January to July. By
placing the review on a fiscal year basis, the GMOC can begin its work in
October and finish by the first part of March. This will enable the GMOC
recommendation to be considered by the City Council prior to Capital
Improvement Program and Annual Budget adoption. This was the original idea in
the Threshold Policy and the GMOC believes this change in schedule will better
serve the City Council.
DEVELOPMENT FORECASTS
In order to look ahead as well as back over past performance, the
threshold/standards policy calls for City staff to prepare development
forecasts at the beginning of the annual GMOC review process. These forecasts
were prepared in February and distributed to the respective agencies for
eva 1 uat i on and report back to the GMOC. Duri ng the 1 ast fi ve years Chul a
Vista has averaged between 1,000 and 1,500 residential building permits per
annum. The high was 2,076 dwelling units in 1986 and the low was 664 units in
1990. In terms of population growth during the past five years, the City has
grown from 116,325 in January 1986 to 135,163 in January 1990, or an increase
of about 3,839 people per year during this time frame.
Looking at building completions and occupancy over the next 18 months, the
Planning Department has estimated that there could be up to 2,124 units
added. This would be comprised of approximately 451 units to be constructed
in the Sweetwater Authority water service area (i.e., the area generally west
of 1-805,) as well as approximately 1,673 dwelling units in the Otay Water
District service area (comprised of those areas generally east of 1-805). The
growth projections for the Otay District area are predicated on the Otay Water
District water allocation program, which is limiting issuance of building
permits to between 700 and 1,000 per year within the City of Chula Vista
portion of the Otay Water District over the next several years. This forecast
does not take into account the current recession, S & L failures, housing
affordability, or the drought, all of which are contributing to an overall
slowdown in housing starts.
J-S
GMOC REPORT
PAGE 3
With regard to long term development forecasts, Planning Department staff has
estimated that a long term growth rate of 300 dwelling units per year could be
realized in the Sweetwater Authority area, and 1,280 dwelling units per year
coul d be constructed in the Chul a Vi sta portion of the Otay Water Di stri ct
service area over the next 7 years. This would result in an annual rate of
growth ranging from 1,500 to 1,600 units per year, for the duration of the
seven year forecast period.
ANNUAL REVIEW OF THRESHOLDS
ISSUES WHERE THRESHOLDS ARE MET
1. Police
THE GMOC FINDS THAT THE POLICE THRESHOLD HAS BEEN MAINTAINED ON BOTH A
CUMULATIVE AND PROJECT BASIS.
In 1990, the threshold for Police services was met for both Priority 1
and Priority 2 calls. The threshold for Priority 1 (emergency calls)
requires that 84% of these calls be responded to within 7 minutes and
that an average response time to all Pri ority 1 call s of 4.5 mi nutes or
less be maintained. The actual performance for 1990 indicated that 87.6%
of all Pri ority 1 call s were responded to wi th in 7 mi nutes and that the
average response time for all priority calls was 4.13 minutes. This
indicates that the threshold standard for Priority 1 calls was met during
1990.
With regard to Pri ority 2 call s (urgent ca 11 s) the threshold standard
requires that 62% of all Priority 2 calls be responded to within 7
minutes, and that an average response time to all Priority 2 calls of 7
minutes or less be maintained. The actual performance for 1990 was that
68% of all Priority 2 calls were responded to within 7 minutes and the
average response time was 6.25 minutes. Again, the data indicated that
the threshold for Priority 2 Police services was met.
The Police Department did not indicate any specific concerns with regard
to its abi 1 ity to cont i nue to meet these standards duri ng the comi ng
year, based on development projections.
2. Fire
THE GMOC FINDS THAT THE FIRE THRESHOLD HAS BEEN MAINTAINED ON BOTH A
CUMULATIVE AND PROJECT BASIS.
The threshold standard requires that 85% of all emergency fire and
medical emergency call s be responded to within 7 minutes. The actual
performance for 1990 was that 92.3% of all emergency calls were responded
to within 7 minutes. These data indicate that the threshold for fire
response was met during 1990.
~"
GMOC REPORT'
PAGE 4
The Fire Department indicated that they did not foresee any specific
problems with meeting the Fire threshold standard during 1991, based on
the development projections that were provided.
Fire Department staff is developing a plan to open a fire station in the
eastern territories to enable the City to maintain the present level of
service.
3. Sewer
THE GMOC FINDS THAT THE SEWER THRESHOLD HAS BEEN MAINTAINED ON BOTH A
CUMULATIVE AND PROJECT BASIS.
There were no major problems attributable to new growth in the City
during calendar year 1990 with respect to the established thresholds for
sanitary sewers. The City design capacity for sewers has been revised to
limit the flow in sewers up to 12" in diameter to 50% full and to 75%
full for sewers larger than 1211. The City has also allowed flow up to
75% full in 811, 1011 and 12" diameter sewers if it can be shown that
ultimate development has already occurred.
However, there were two major developments in the planning stage during
1990 which would discharge into sewers flowing near or over design
capacity. These are the Palomar Trolley Center and the Scripps Memorial
Hospital expansion. Since sewers along Industrial Blvd. have peak flows
over design capacity, use of a sewage holding tank would be required for
a development in this area prior to construction of a planned relief
sewer. Since a portion of the sewer lines on "GII Street and IIH" Street
are flowing near or over design capacity at times of peak flow,
preparation of a technical report analyzing impact of flows from the
Scripps Memorial Hospital expansion and recommending necessary
improvements was required.
The City is using several methods to identify and determine the cause of
peak flows exceeding City standards in existing sewers. The City's sewer
TV inspection crew continues to monitor problem sites in order to
determine if the condition of the sewer lines has affected the flow.
The Wastewater Master Plan prepared in 1989 includes an analysis of
current and projected future flows for all City trunk lines and provides
recommendat ions for construct i on of new and upgraded sewers and
preliminary cost estimates. In addition, adequacy of sewers must also be
addressed in the environmental documents of proposed new developments.
Sewage facilities identified through these methods may be considered for
inclusion in the Capital Improvement Program or the Sewer Rehabilitation
Program. Construct i on work on Phase I I I of the Sewer Rehabi 1 i tat ion
Program has recently been completed based on information obtained by TV
inspect i on of sewer 1 i nes. New developments wi 11 be requ i red to pay a
proportionate share for the construction of new sewers needed.

GMOC REPORT
PAGE 5
The City is currently under contract for preparation of the Telegraph
Canyon Sewer Basin Improvement and Financing Plan. This plan is to
estimate current and ultimate sewage flows, recommend necessary sewerage
system improvements, and determine fees or a funding mechanism to finance
these improvements.
With respect to sewer capacity, the City's total daily wastewater flow
into the Metro Sewage System is approximately 12.8 million gallons per
day (mgd). This includes 10.5 mgd of metered flows and 2.3 mgd of
unmetered flows which discharge to the Spring Valley Sanitation
District. The installation of six new permanent metering stations during
the current fiscal year will enable the Spring Valley flows to be more
accurately measured.
The City's existing sewage capacity reservation with Metro is 19.2 mgd
including the Montgomery area. The Engineering Science plan predicts
that the flow rate would reach the available capacity by the year 2000.
However, since the plan uses an existing flow of 13.5 mgd for 1990, 0.7
mgd more than the actual flows, the projected dates for reaching capacity
flow will need to be re-eva1uated.
It is projected that the ultimate average daily wastewater flow of 25.1
mgd will be reached in about the year 2020. A consultant is currently
completing a study which will evaluate wastewater treatment, disposal and
reclamation alternatives and determine the most cost-effective method of
providing for the City's current and future needs. Additional technical,
financial and legal consultants will be retained in FY 91-92 to aid in
the decision-making process.
The City of San Diego Water Utilities Department was asked to comment on
the availability of future sewer capacity to accommodate Chu1a Vista's
01 anned qrowth as projected in the Development Forecasts. There is a
concern reqardinq the ability of the Metropolitan Sewaqe System to
accommodate Chu1a Vista's future flow rates in accordance with our 19.2
mqd sewer capacity reservation. The City of Chu1a Vista has not received
a response from the City of San Diego reqardinq this matter.
4. Drainage
THE GMOC FINDS THAT THE DRAINAGE THRESHOLD HAS BEEN MAINTAINED ON A
CUMULATIVE AND PROJECT BASIS.
No major problems can be attributed to new growth in the City during
calendar year 1990 concerning the threshold standards for drainage. One
reason for this is that developers have constructed detention basins such
that downstream flows are not increased. Each new subdivision is
required to construct all drainage facilities to handle storms of a
certain magnitude and discharge the flows into a downstream facility.
The Envi ronmenta 1 Impact Report for each development must address any
possible drainage problems either on-site or off-site. The developer is
required to implement mitigation measures, if necessary.
2-'
GMOC REPORT
PAGE 6
In addition to the construction of drainage facilities, developers will
shortly be faced with a need to obtain National Pollution Discharge
Elimination System permits for each grading operation affecting an area
of five acres or more. The requirements for these permits will be based
upon the need to prevent pollutants from reaching drainageways.
The permits are to be issued by both the Regional Water Quality Control
Board and this City. Details of this aspect of the NPDES program are not
fully worked out yet, but the EPA regulations callout November 16, 1991
as the date when applications must be submitted.
The permit from the Regional Water Qual ity Control Board which the City
operates under provides for implementation of a Best Management Practices
Program covering this activity to be started January 31, 1992.
Developers will be required to dedicate land and construct facilities
necessary to serve their proposed developments. Facilities benefiting an
extensive area with multiple owners may be financed through assessment
districts.
5. Libraries
THE GMOC FINDS THAT WITH THE APPROVAL OF THE STATE LIBRARY FUND GRANT OF
$6.85 MILLION TO CONSTRUCT A NEW LIBRARY IN MONTGOMERY, THE CITY HAS
ACHIEVED CONFORMANCE WITH THE LIBRARY THRESHOLD ON A CUMULATIVE BASIS.
The threshold standard for libraries requires that 500 sq. ft. of library
space (adequately equipped and staffed) be provided per each 1,000
population. Based on a population estimate of 135,163 as of December 31,
1990, a total of 67,582 sq. ft. of 1 ibrary space would be required,
whereas currently 57,329 sq. ft. is provided in the Chula Vista Public
Library as well as two branch libraries. This results in a shortage of
library space of 10,253 sq. ft. The objectives contained in the
threshold for 1 ibraries recommends that the City supplement the Central
library facility by providing branch library facilities in the
Montgomery/Otay area and in the area east of I-80S.
On August 16, 1990 the City Council adopted a resolution (1) authorizing
Library staff to prepare a pre-application and application for California
Library Construction and Renovation Bond Act Funds; (2) Approving the
proposed Orange and Fourth Avenue park site for the library and (3)
appropriating $114,500 for the required professional design services for
the applications submission.
On November 21, 1990 the Chula Vista Public library filed a Preliminary
Application with the California State Library to apply for California
Li brary Construction and Renovation Bond Act funds for the construct i on
of a 35,000 sq. ft. library in the Montgomery/Otay Planning Area. The
Bond Act authorizes $75 million in bonds to be issued for public library
construction and renovation, including new buildings. The Bond Act
provides that the funds be awarded on a 65% State/35% local matching
basis by a five person board.

The Chula Vista Public Library has also been allocated $200,000 in the FY
1990-91 Capital Improvement Program to hire an architect to begin design
work on a 24,000 sq. ft. 1 ibrary to be built at the corner of H Street
and Paseo Ranchero in the Sweetwater/Bonita Pl ann i ng area. The Library
intends to begin the architect selection process in the Spring of 1991.
An additional $266,000 has been requested in FY 1991-92 to complete the
design work through construction drawings.
Work on a 4,000 sq. ft. store front 1 i brary in East 1 ake Vi 11 age Center
has been put on hold since the Eastlake Development Company has not yet
finalized construction plans for that commercial complex.
6. Economi cs
THE GMOC FINDS THAT THE ECONOMIC THRESHOLD HAS BEEN MAINTAINED ON A
CUMULATIVE BASIS.
The economics threshold standard was revised last year (1989 GMOC REPORT)
by the City Council to provide the GMOC with an annual fiscal report to
show an evaluation of the impacts of growth on the City in terms of
operations and capital improvements and to also provide the GMOC with an
annual economic monitoring report to provide an analysis of economic
development activity over the previous year as well as looking at future
conditions. The GMOC is to evaluate the fiscal and economic effects of
growth and report any adverse impacts or recommended actions.
The Annual F i sca 1 and Economi c Report was prepared for the GMOC. In
order to have accurate data, the fiscal year 1989-90, which ended June
30, 1990, was analyzed.
The report revealed the beginning effects of the recession on certain
revenue accounts, however, the imp 1 ementat i on of the Publ i c Facil it i es
Development Impact Fee during 1989-90 provided a new source of revenue
from new development. The largest dollar increase in expenditures was in
the Police Department which snowed an increase of $1,670,961, or 11.8
percent.
The fiscal impact analysis of forecasted growth reveals a fiscally
positive result based upon the 12 to 18 month development forecast. The
annual net impact (revenue minus expenditures) is projected to have a
surplus of $135,000. This produces a revenue/cost ratio of 1.13 which is
generally considered a favorable result.
2-/ /J
GMOC REPORT
PAGE 8
The five to seven year forecast also projects positive results, but to a
lesser extent. The estimated revenue/cost ratio is 1.06 which is still
on the plus side, but not as large as the short term forecast.
In terms of economi c act i vi ty, i ndi cators showed cont i nued steady growth
with respect to taxable sales transactions and increases in assessed
value of property (plus 13.3%). Residential construction dropped by 36.5
percent between calendar year 1989 and 1990. This is due to the
recession and also to Otay Water District's water allocation program.
The GMOC felt that future reports should address the fees collected by
the City through the Transportation Development Impact Fee, Public
Facilities Development Impact Fee and the Park Dedication Fee and
document how such fees were spent and/or credits granted to developers
where facilities were built in lieu of fees.
The GMOC also concluded from the Annual Fiscal and Economic Report that
there are no significant fiscal or economics problems that warrant
special attention. The conclusions of the report found that the growth
that occurred over the 1 ast 12 -month peri od had a pos it i ve fi sca 1 impact
on the City's fiscal well-being. The report also forecasts that over the
next 12-18 months and the next five to seven years, the same relationship
is projected to continue. Thi s forecast will be revi ewed each year and
future forecasts will be revised accordingly.
With respect to the long-term, the report suggests paying close attention
to the need to expand both industrial and retail growth in order to
maintain a positive revenue/cost relationship to support city services.
In future years, the GMOC will continue to monitor the fiscal/economic
impacts of growth to see how well the forecasts track over time and
identify structural problems before they become serious.
This is a pioneering effort and will involve a certain degree of
refinement of the analysis in the future. The GMOC would point out that
the analysis shows a significant fiscal difference between
Commercial/Industrial and Residential growth from a fiscal point of
view. The commercial/industrial type of growth is positive on City
revenues and a certain amount of Commercial/Industrial growth is
absolutely necessary to support city services.
7. Parks and Recreation
THE GMOC FINDS THAT THE PARKS AND RECREATION THRESHOLD HAS BEEN
MAINTAINED ON BOTH A PROJECT AND CUMULATIVE BASIS.
The Parks and Recreation threshold is a population based standard calling
for 3.0 acres of neighborhood and community park land to be provided for
every 1,000 residents east of 1-805. Last year, the GMOC recommended
that the threshold standard for parks be revised to include a consistent
standard for a 11 new development. The GMOC recommendat i on is that the
goal is to have the three (3) acres per 1,000 population city-wide.
2"'//
GMOC REPORT
PAGE 9
At the en9 of 1989, the City had a population of 131,603 and park acreage
totalling 299.15 acres, for a ratio of 2.27 acres per 1,000 population.
At the end of 1990, based upon population estimates of 135,522 and park
acreage totalling 317.65 acres, the population ratio increased to 2.34
acres per 1,000 population. For the area east of I-80S, based on a 1990
estimated population of 36,448 and park acreage of 188.5 acres, the
population ratio is 5.17 acres/1,OOO people. Therefore, the existing
threshold standard has been met and actually exceeded.
In 1990, two new City parks were constructed. Sunbow Park, a four acre
neighborhood park was completed by the developer of Sunbow and Discovery
Park, a 14..5 acre community park was completed by the Rancho del Rey
developer.
In 1991, a number of renovation and construction projects should be
compl eted. Memori a 1 Park, Norman Park Senior Center, Parkway Community
Center, Parkway Pool, Lorna Verde Pool, Community Youth Center and Tennis
Courts at two high schools will be improved. In addition, construction
of Eastlake Community Park and Terra Nova Park expansion should begin.
For Fiscal Year 1989-90, the City collected $144,030 in PAD fees, of
which $19,110 was from west of I-80S. The PAD fees were increased by
Council on April 24, 1991, and this should provide additional funds for
park construction projects in future years.
With respect to last year's GMOC recommendations, the following indicates
the current status of each:
a. Revise park threshold standard west of 1-805.
The Parks and Recreation Department report to Council
dated April 2, 1991 recommended that staff be directed to
bring back for future Council consideration changes to the
Threshold Standard. The GMOC would repeat its same
recommendation from last year's report regarding changing
the threshold standard for parks to include a standard for
new development west of 1-805, as well as addressing park
deficiencies for existing residents west of I-80S.
b. Adopt a specific definition of net usable acreage when calculating
park ac:reaqe.
Parks and Recreat ion Department is worki ng to refi ne the
suggested net usabl e acreage cri teri a recommended by GMOC
and will bring appropriate changes to the Parks Dedication
Ordinance to Council at a future date.
3. -I;'
GMOC REPORT
PAGE 10
c. The City Council should adoot a requirement that all new
multi-family residential development provide private recreational
areas (i.e.. tot lots) wherever possible.
The Parks and Recreation Department has requested
i ncl us i on of small grassy areas and a tot lot when no
private recreational facilities are shown for new
apartments. Staff has been directed to prepare changes to
the appropriate City code to make this recommendation a
requ i rement and bri ng the item back to the City Counc il
for approval.
d. Park fees should be charged for all new residential development.
rather than only for developments which require tentative mao
aoorova 1 . At the present time, apartment projects are not charqed
PAD fees.
PAD fees can only be assessed for residential development
on a subdivision map or parcel map per State law.
However, staff is researching other ways for assessing
apartment projects, a park fee at the building permit
stage for smaller residential as well as commercial and
industrial projects. Parks and Recreation Department is
working on a "Park Benefit Fee" and a Park Development
Impact Fund to address this need.
e. Park Acquisition and Development (PAD) Fees should be used solely
for acquisition and development of new parks rather than for repair
and maintenance of existing park facilities.
PAD fees cannot be used for maintenance due to State law.
Such fees have been used to renovate existing neighborhood
and community parks, recreation centers and for
development of new parks. Due to the shortage in PAD fees
to construct new parks west of 1-805, the City Council
concurred with the Parks and Recreation Department and
Parks and Recreation Commission that PAD fees shall
continue to be used for upgrades and enhancements to
local/neighborhood parks and community parks and
facilities, recreation centers/pools/gyms and specialty
parks since these facilities are of a community-wide
benefit and use.
The GMOC wishes to re-emphasize the need for the City to complete the
necessary work to implement last year's recommendations as set forth in
'a' through 'd' above.
New Recommendations:
a. In addition, the GM~C recommends that the City adopt a long range
plan to expand existlng parks or provide additional new parks in the
area west of 1-805 to meet the needs of existing residents, with a
~-/3
GMOC REPORT
PAGE 11
goal of meeting the standard of three acres per 1 tOOO people on a
Citywide basis within 20 years. The implementation of this plan
should be funded by new revenue sources in addition to PAD fees.
b. The GMOC supports the Parks and Recreat i on Department proposal to
charge fees to non-residents of Chula Vista for reservation of park
facilities for groups only.
8. Traffic
THE GMOC FINDS THAT THE TRAFFIC THRESHOLD HAS BEEN MAINTAINED ON BOTH A
CUMULATIVE AND PROJECT BASIS.
The GMOC reviewed a report entitled 1990 Traffic Monitoring Report (See
Attachment D). The report provides an assessment of the current
operational status of 109 signalized intersections based on existing
conditions. The report findings disclosed an improvement from last
year's conditions at critical intersections.
The report revealed that of 109 intersectionst a total of seven
intersections experienced congested operations with levels of service
ranging from D to E. This compares with last year's report which found a
total of 13 intersections operating with levels of service ranging from D
to E. The improvement may be in part, due to the connection of SR 54
from 1-5 to 1-805 in December of 1990.
The Traffic: Monitoring Report al so addressed the methodology that the
city uses in assessing traffic conditions throughout the City. The City
has been us i ng the Intersect ion Capac ity Ut il i zat i on (ICU) method for
calculating capacity and levels of service at signalized intersections.
The ICU method is a short-cut procedure to manually determine the
crit i ca 1 volume to capac ity rat i 0 of the intersect ion. By way of
contrastt the 1985 Highway Capacity Manual (HCM) technique completely
redefines LOS as a function of vehicle Stopped Time Delay. In additiont
the HCM method also provides a measurement for the direct calculation of
delay based upon:
Volume
Saturation Flow Rate
Lost Time
Cycle Length
Phase Time
Progression
The actual delay experienced by the motorist when traveling along a
segment of the street system with four or five signalized intersections
is the essence of the HCM method. The HCM method is superi or to ICU
because signal timingt progressiont and cycle lengths have a greater
impact on Level of Service than the ICU's simplistic volume/capacity
ratio. With ICUt low V/C ratios do not necessarily indicate good levels
,. -/~
GMOC REPORT
PAGE 12
of service, and high V/C ratios do not necessarily indicate poor levels
of service. The GMOC agrees with the change from ICU to HCM recommended
by the JHK Report and the City Traffi c Engi neer and recommends that the
City Council adopt the revised Traffic Threshold Standard attached to
this report. The new Traffic Threshold Standard does not lower the LOS
Standards that have been in existence since 1987.
The cost of monitoring the existing system is estimated to be
considerably less (perhaps 50%) than previous traffic monitoring studies
because much of the work can be automated.
After this new traffic threshold standard has been put in place, the GMOC
will reevaluate its effectiveness on an annual basis.
The two GMOC recommendations made last year regarding changing the
Traffic Threshold Standard No. 3 and replacing language in item 3, Notes
to Standards in the Threshold Standards were both adopted by the City
Council on April 23, 1991.
H Street Corridor
The GMOC also reviewed the H Street Corridor Report prepared by the City
staff. The report addresses: (1) the re 1 at i onshi p between growth and
development in the Eastern Territories Planning Area and the resultant
traffic activity on H Street; and (2) documents the importance of
redesignating H Street between Hilltop Drive and Third Avenue as a
six-lane major street.
The conclusions of the report are as follows:
Existing roadway capacity on H Street (for four lanes) adequately
serves current travel demand with the exception of poor level of
service on H Street and Hilltop Drive during the PM peak hour.
The interaction of tri ps result i ng from current and future Eastern
Territories Planning Area development contributes significantly (in
excess of 50 percent of traffic activity on H Street west of I-80S
in Years 1990, 1995 and buildout).
The remaining buildout of the Eastern Territories Planning Area
represents a smaller share of all traffic (52 percent) than what
exists today (56 percent) on H Street west of I-80S. However, it is
recognized that this contribution is still significant in the
long-term (forecasted to be in excess of 50 percent).
The recommendations of the City staff regarding H Street Corridor are:
Near-Term Measures
Focus future geometric improvements at signalized intersections
where impediment to traffic flow are greatest. This measure may
forestall the need for mid-block widening.
~-J~
GMOC REPORT
PAGE 13
Prohibit on-street parking along critical mid-block segments to
increase capacity and improve traffic flow.
Lonq-Term Measure
Study a General Plan amendment for a six-lane facility.
Adopt a minimum roadway width standard to minimize impacts of future
widening on adjacent properties.
For segments west of Fourth Avenue, the City shall require roadway
widening in addition to right-of-way dedication to implement the
modified roadway width standard as a condition of development.
For the segment between Third Avenue and Fourth Avenue the City may
defer mid-block widening and focus on improving intersection
capacity.
The GMOC is concerned that future increases in traffic on H Street may
contribute to a threshold standard problem in the future unless
mitigation measures are carried out by the City.
THRESHOLDS REFLECTING STATEMENTS OF CONCERN
1. Air Quality
THE GMOC RECOMMENDS THAT THE CITY COUNCIL ISSUE A STATEMENT OF CONCERN TO
THE AIR POLLUTION CONTROL DISTRICT (SEE ATTACHMENT B).
The APCD provided the GMOC a summary of the requirements of the
California Clean Air Act of 1988. The Act requires the APCD to prepare a
new plan for smog, carbon monoxide, and nitrogen dioxide that meets State
standards and submit the pl an to the State Ai r Resources Board by June
30, 1991.
The APCD staff is complimented on providing a much improved report to the
GMOC this year which contained considerable information regarding the
State Clean Air Act of 1988 and regional planning regarding the status of
compliance.
One of the requirements of the plan is transportation control measures.
Since on-road motor vehicles are the predominant source of smog-forming
po 11 ut i on (hydrocarbon and oxi des of nitrogen), the State 1 aw requi res
that regional air quality plans reduce emissions from all sources of at
1 east 5 percent per year until attainment. To meet the State standards
of 5 percent emission reduction per year, emissions of both reactive
organic gases and oxides of nitrogen need to be reduced by 65 percent by
2000. Some of this reduction will be achieved by industrial and new
motor vehicle controls, but to achieve the 5 percent reduction will
require implementation of all feasible transportation control measures,
. .2..1'-
GMOC REPORT
PAGE 14
which include as a mlnlmum a single passenger vehicle trip reduction
program, a parking management program, a truck operation program, an
alternative transportation mode capacity expansion program,
transportation system management, land use and an indirect source review
program.
The Indirect Source Review Program (an indirect source is any source
which, by itself does not necessarily emit air pollution but generates
pollution by the fact that it attracts vehicle trips) will be of
particular interest to Chula Vista. The indirect source control
regulation adopted by APCD will be delegated to Chula Vista only if we
adopt an air quality element or otherwise implement air quality programs
conforming to the APCD indirect source control regulation. This
regulation will need to be carefully reviewed by the City prior to
adoption by APCD and the State Air Resources Board.
Last year the GMOC recommended to Council that a Statement of Concern be
transmitted from the City of Chula Vista to the APCD concerning several
issues.
The three concerns from last year were as follows:
a. A general lack of leadership by the APCD in dealing with the impacts
of growth on air pollution.
The GMOC still has not received any information from APCD
as to major sources of air pollution in the City of Chula
Vista. The GMOC is particularly interested in major
industrial facilities such as SDG&E, Rohr, etc. We are
interested in knowing if there are any industrial uses in
violation of APCD standards and, if so, what is being done
to enforce regulations.
b. A lack of direction by the APCD to the local agencies in how to deal
with the impacts of local growth on air pollution.
APCD is proceeding with the new Regional Air Quality
Strategy required by the State Clean Air Act of 1988 and
this plan is scheduled for completion in the third quarter
of 1991.
c. A concern regardinQ the impacts on air pollution by the proposed new
power plant and aUQmentation of the existing power plant at the
South Bay site by San DieQo Gas and Electric.
This concern is on hold since APCD staff has indicated to
the GMOC that SDG&E has withdrawn the application for the
proposed augmentation in the South Bay as a result of the
proposed merger.
~-'7
GMOC REPORT
PAGE 15
Last year the GMOC also made four recommendations as follows:
a. That the APCD update the San Dieqo County Air Quality Manaqement
Plan at the earliest possible date. and provide direction to local
aqencies as to how they can ensure that reqional air Quality
standards are met on a local basis.
Thi s recommend at i on wi 11 be met by APCD's current effort
to prepare the new regional Air Quality Strategy which is
in process and due to be completed this year for
submittal to the State Air Resources Board.
b. Tha t the APCD work with the Cali forn i a Enerqy Commi ss i on to
ensure that air Quality is not adversely impacted by the new
power plant and auqmentation of the South Bay plant proposed
by San Dieqo Gas and Electric.
The procedure regarding this recommendation is for the
application to be filed directly with the State Energy
Commission and then the Energy Commission goes to the Air
Pollution Control District to determine the type of
permits that are required.
c. That the APCD i dent ify the major sources of air poll ut ion in Chul a
Vista. includinq an evaluation of the impacts of landfills (methane
emissions) on air quality.
The APCD reports that methane emissions from landfills
does not contribute to the regional ozone problem. The
i nformat i on requested 1 ast year concerni ng major sources
of pollution in Chula Vista is still a concern since the
APCD has not furnished the GMOC the requested information.
d. That the City support the use of efficient mass transportation as a
means of mitiqatinq air Quality impacts.
The last recommendation regarding the use of efficient
mass transportat i on has been endorsed by the APCD in its
adopted Transportation Control Measures Criteria entitled
Alternative Transportation Mode Capacity Expansion.
The GMOC also noted that APCD historically has not enlisted the support
of cities in controlling industrial sources of air pollution.
According to the APCD staff, about 90 percent of the total amount of air
pollution coming from industrial sources in Chula Vista is coming from
SDG&E's bo il ers.
J. -18
GMOC REPORT
PAGE 16
The GMOC would like to receive information about the Air Quality in Chula
Vista and any information as to what is actually being done in the
investigation of air pollution. City staff offered to meet with APCD to
simplify the request for information.
There has been much improvement from 1 ast year and the GMOC recommends
more frequent communication and exchange of information on a regular
basis. The City needs much more guidance in responding to APCD air
quality program. At present, the City receives no information from APCD
regarding enforcement activities or periodic inspections.
2. Water
THE GMOC RECOMMENDS THAT THE CITY COUNCIL ISSUE STATEMENTS OF CONCERN TO
BOTH THE SWEETWATER AUTHORITY AND THE OTAY WATER DISTRICT (SEE ATTACHMENT
~
The GMOC was briefed on efforts of the Inter-Agency Water Task Force to
address drought related issues. It was noted that the City of Chu1a
Vista had saved 14.1 percent over the previous year.
Some of the things that may be done in the future include:
,
1) Improve collection of run-off because during periods of
rainfall, much of the water is lost to the ocean.
2) Use reel aimed water. The County Water Authority has pl ans for
200,000 acre feet by the year 2010.
3) Study desalination of sea water, although this could be four to
five times as expensive as imported water, at present.
4) Changes in the types of landscaping and lifestyle which can
produce significant reductions in water use.
Last year's GMOC report identified the areas of concern as:
a. A concern about the long-term water supply situation, and the need
to coordinate efforts among the Water Districts and the City.
The Inter-Agency Water Task Force was formed to do a better
job of coordinating efforts to provide water service to
address the long term water supply situation. Additional
water has been stored in the Sweetwater Reservoi r for a
1992 drought reserve. The Sweetwater Authority has a
better reserve now than two years ago.
b. The proposed Bayfront project may create probl ems for the exi st i ng
facilities of the Sweetwater Authority.
Rohr Industries corporate headquarters building of some
265,000 square feet wi 11 have fi re f1 ow demands of 5 000
gallons per minute. The water district does not have that
~-I'
GMOC REPORT
PAGE 17
kind of delivery capacity since there was no need for it in
the past. Rohr will be upgrading the water supply system
from existing Sweetwater Authority storage reservoirs on
Oxford Street and at Bonita Valley to provide the required
5tOOO gpm fire flow. These improvements will be paid for
by Rohr and are estimated to cost approximately $.5 million.
3. School s
THE GMOC RECOMMENDS THAT THE CITY COUNCIL ISSUE STATEMENTS OF CONCERN TO
BOTH THE SWEETWATER UNION SCHOOL DISTRICT AND CHULA VISTA ELEMENTARY
SCHOOL DISTRICT (SEE ATTACHMENT B).
a. Sweetwater Union High School District
The 1990 report from Sweetwater Union High School District included
only the eight schools located within the City of Chula Vista.
Previous reports included the entire district and was based on the
CBEDS datat giving the GMOC information on the housing of students
in addition to the count.
Sweetwater Union High School District reported that they are in
comp 1 i ance with the threshold standards. The current capac ity of
the four high schools within the Chula Vista area of the district is
7.084 studentst and the current student population is 7.012
studentst so there is capacity for the students. Howevert this
capacity includes relocatable trailers that have a capacity of 960
students.
The key statistic with respect to the four junior high schools
within the Chula Vista area is that ,the total capacity is 5,886
students and the current student population is 5t867 students.
While there is city-wide capacity this yeart the Bonita Vista Junior
High is over capacity by approximately 208 students.
The following measures are under consideration to alleviate
overcrowded conditions:
The anticipated opening of Eastlake High School in the Fall of
1992.
Boundary adjustments in the attendance areas for the Bonita
Vista High and Bonita Vista Junior High Schools.
Proposed boundary adjustments in the attendance areas for the
Montgomery High and Southwest High Schools.
The anticipated opening of the Youth Facility at Chula Vista
High School.
J--~O
GMOC REPORT
PAGE 18
The anticipated construction of 10 new classrooms at Chula
Vista Junior High School.
It is anticipated that with these changes the enrollment levels at
Bonita Vista Junior, Bonita Vista High and Castle Park High will be
brought down to more acceptable levels.
Based on the Sweetwater Union High School District reports and
conclusions, the GMOC has determined that conditions have not
changed significantly from last year.
The District also reported that there are 44,000 people attending
adult school classes, which is an average of about 5,600 students
per day. In the last two years, the District has added 22
classrooms to accommodate these students.
The GMOC is also concerned that the airport master plan study of
Brown Field and the proposal to locate a twin port international
airport at the U.S.-Mexico border on Otay Mesa may be contributing
to overcrowded schools in Chula Vista. The reason for this concern
is because the high school district is apparently unable to obtain
State approval of new school sites on Otay Mesa until the airport
issues are resolved. In the meantime, the district is experiencing
continued growth but is unable to construct new schools in the Otay
Mesa portion of the district. Thus, the remaining areas of the
district such as Chula Vista may continue to be impacted until
relief is provided by the construction of new schools.
b. Chula Vista Elementary Schools
Last year in response to the City's 12 to 18 month growth forecast,
the District identified seven of the 12 schools in the western
portion of Chula Vista projected to be over capacity by
approximately 481 students. This growth was accommodated through a
combination of busing, facilities modifications and program changes.
This year, the City estimated that within the western portion of
Chula Vista, 135 children would be generated by new development.
This growth will contribute to further overcrowding of the affected
schools.
The opening of Clear View School which is located in the Terra Nova
area in September 1991 will provide additional capacity (550
children) and some relief for western area schools.
New development with in the Eastern Territori es is provi ded school
facilities through the voluntary establishment of Mello-Roos
Community Facilities Districts. Approximately 502 new students are
projected over the next 12 to 18 months.
~...3-'
GMOC REPORT
PAGE 19
The report from the Chula Vista City School District staff described
a number of activities the District is undertaking to keep abreast
of changing conditions.
The new school planned in the Rancho del Rey Community will be
postponed for a year due to the economi c slow down and the water
allocation policy of the Otay Water District.
The GMOC is concerned about the continuing overcrowded school
conditions in western Chula Vista. The GMOC noted that Clear View
School will be opening on time and that the District is using a
number of strategies to address the overcrowded conditions including
individual school growth studiest residency verificationt and
pursuing redevelopment money. The District has also been more
forthright in stating thei r concerns regardi ng the impact of new
projects in western Chula Vista such as Trolley Squaret "H" Streett
Scripps Hospital expansion on the school district.
Concerns were also expressed by the District regarding the impact of
the General Plan Amendment and re- zon i ngs of the central port i on of
Chula Viista which generated a recommendation that the City include a
condition to require compliance with school district facility
mi t igat i on recommendations. Thei r recommendation was also made to
the Planning Commission at their April 10,1991 meeting following
review and action on this General Plan Amendment.
The GMOC commends the Chula Vista Elementary School District for
their outstanding report. The GMOC strongly emphasizes the need for
policy llevel solutions between the City Council and the Chula Vista
Elementa.ry School District Board for the problems identified in the
District's report to the GMOC.
c. School Unification
The latest information indicates that the County School Board
approved two petitions for unification and the election could occur
as early as June 1992.
The GMOC re-emphasizes the discussion regarding school district
unification from last year's report which statedt "The GMOCt without
taking a position at this time on the issue of school district
unification supports the idea of a study on the advantages and
disadvantages of establishing a Unified School District grades K-12
for the Chula Vista area. This study would be a significant
undertak.ing which is beyond the scope of the GMOC but we feel would
be beneficial to the community in light of the difficulties facing
both districts in meeting the educational needs of the community."

OTHER AREAS REVIEWED BY GMOC
Solid Waste and Recycling
In the GMOC Second Annual Report, it was determined that based on a review of
the information regarding AS 939 (Solid Waste Management Act of 1989), that it
was not necessary to recommend adoption of a specific standard for solid waste
management. It was also concluded that the City should establish baseline
information regarding local solid waste generation within the City of Chula
Vista as soon as possible, in order that it can properly evaluate whether the
required reduction under AB 939 are being met.
The GMOC received excellent reports from City staff on the recycling program
adopted by the Ci ty. The GMOC determi ned that there is no need for further
review of this function. The City is encouraged to promote the use of
recycled materials because they are essential to a successful recycling
program.

To establish a performance standard which is consistent with the Regional
Growth Management Standards.
To maintain consistency in terms of LOS ratings between the previous
Intersection Capacity Utilization (ICU) methodology and the 1985 Highway
Capacity Manual (HCM) methodology.
OBJECTIVES
1. Ensure timely provlslon of adequate local circulation system capacity in
response to planned growth, maintaining acceptable levels of service
(LOS).
2. Plan new roadway segments and signalized intersections to maintain
acceptable standards at build-out of the General Plan Circulation Element.
THRESHOLD STANDARDS
City-wi de: Ma i nta in LOS 'c' or better as measured by observed average
travel speed on all signalized arterial segments except that during peak
hours a LOS of '0' can occur for no more than any two hours of the day.
West of I-80S: Those signalized arterial segments which do not meet the
standard above, may continue to operate at their current (Year 1991) LOS,
but shall not worsen.
Notes to Standards
Arteri a 1 segment LOS measurements sha 11 be for the average weekday
peak hours, excluding seasonal and special circumstance variations.
Urban and suburban arterials are defined as surface highways having
signal spacing of less than 2 miles with average weekday traffic
volumes greater than 10,000 vehicles per day.
Arterial segments are stratified into three classifications:
Class I arterial s are roadways where free flow traffic speeds
range between 35 mph and 45 mph and the number of signal i zed
J .11.-
._,.........._-_._>,-,..,.....,-,.~~,-
Notes to Standards (continued)
intersections per mile are less than four. There is no parking
and there is generally no access to abutting property.
Class II arterials are roadways where free flow traffic speeds
range between 30 mph and 35 mph, the number of signalized
intersect i on per mil e range between four and ei ght, there is
some parking and access to abutting properties is limited.
Class III arterials are roadways where free flow traffic speeds
range between 25 mph to 35 mph and the number of signal; zed
intersections per mile are closely spaced. There is
substantial parking and access to abutting property is
unrestricted.
The LOS measurements of arterial segments at freeway ramps shall be
a growth management consideration in situations where proposed
developments have a significant impact at interchanges.
Circulation improvements should be implemented prior to anticipated
deterioration of LOS below established standards.
The criteria for calculating arterial LOS and defining arterial
lengths and classifications shall follow the procedures detailed in
Chapter 11 of the 1985 Highway Capacity Manual (HeM) and shall be
confirmed by the City Traffic Engineer.
During the conduct of future Traffic Monitoring Program field
surveys, intersections experiencing significant delays will be
identified. The information generated by the field surveys will be
used to determine possible signal timing changes, geometric and/or
traffi c ope rat iona 1 improvements for the purpose of reduci ng
intersection delay.
Level of service values for arterial segments shall be based on the

EXECUTIVE SUMMARY
ANNUAL FISCAL/ECONOMIC REPORT
JUNE 1991
2""'-
EXECUTIVE SUMMARY
GROWTH MANAGEMENT OVERSIGHT COMMISSION
ANNUAL FISCAL AND ECONOMIC REPORT
MAY 1991
In 1990 the economics threshold of the City's Growth Management Program was revised to read:
a. The GMOC shall be provided with an annual fiscal impact report which provides an
evaluation of the impacts of growth on the City, both in terms of operations and capital
improvements. This report should evaluate actual growth over the previous 12-month
period, as well as projected growth over the next 12-18 month period, and 3-5 year
period.
b. The GMOC shall be provided with an annual "economic monitoring report," which provides
an analysis of economic development activity and indicators over the previous 12-month
period, as well as projected growth over the next 12-18 month period, and 3-5 year
period.
The Planning Department retained the local government fiscal consulting firm of John McTighe
& Associates to prepare this annual report. John McTighe & Associates has prepared fiscal
analyses for all of the major development projects in the city over the past eight years. John
McTighe & Associates also assisted P&D Technologies with the preparation of the fiscal analysis
of the General Plan Update prepared in 1989.
FISCAL IMPACT ANALYSES
The fiscal impact analyses were prepared using the same basic fiscal impact models that have
been used to analyze the fiscal impacts of proposed development projects and the General Plan
Update. In the case of the analysis of the fiscal impact of the actual growth "over the previous
twelve month period," the analysis actually covers the period between July 1989 through June
1990. In order to have accurate expenditure and "revenue amounts that could be analyzed, it was
necessary to use the most recently completed fiscal year. That is fiscal year 1989-90, which
ended on June 30, 1990. Since the impact of growth on the City's revenues and need to provide
services is generally not immediately felt (except for development fees and planning & building
processing), the use of the actual expenditures and revenues of the City is believed to be an
accurate reflection of the impact of growth on the City's fiscal well being.
Previous Twelve Month Period
This analysis has reviewed the changes in the City's actual expenditures and revenues between
fiscal year 1989 and fiscal year 1990. The analysis has examined the changes in the individual
~-37
departments and activities and the various revenue accounts in the general fund and selected
special funds.
The analysis shows uneven results on both the expenditures and revenues. It makes particular
note of the growth in the Planning and Public Works Departments 'related to new development
in the City. The significant 49% increase in the expenditures of the Planning Department were
related to the additional expenditures for the Otay Ranch joint planning project and increases in
department staff and consultant services to process the general plan update and several large
scale projects that were in process during 1989-90. Much of these costs were directly offset
by reimbursements from the affected developers. In terms of dollar increases, the largest was
in the Police Department which showed an increase of $1,670,961, or 11.8%. Approximately
half of this increase was attributed to inflation, while the other half was a result of additional
staffing to maintain the population to staff ratio.
Those revenues that are directly related to new development showed an overall decline between
1988-89 and 1989-90 as the amount of new development slowed from the previous year.
However, the City implemented the Public Facilities Development Impact Fee during 1989-90
which provided a new source of revenue from those developments which did receive building
permits in that year.
Twelve to Eighteen Month Forecast
The fiscal impact analysis based on the current twelve to eighteen month forecast projects that
the combination of residential and non-residential development contained in that forecast will
have fiscally positive results on the City's operations and maintenance budget. The annual net
impact (revenue minus expenditures) after buildout of this forecast is projected to be a surplus
of approximately $135,000. This produces a revenue/cost ratio of 1.13 which is generally
considered a favorable result. One reason for the relatively high ratio is the amount of office
and industrial acreage contained in the short term forecast.
Three to Five Year Forecast
The "three to five year forecast" is actually based on the five to seven year growth forecast
presented to Growth Management Oversight Commission earlier this year. This fiscal analysis
also projects positive results on the City's fiscal condition, but to lessor extent. At buildout of
the forecast, it is projected that the new development will cause an annual surplus of
approximately $490,700. This produces a revenue/cost ratio of 1.06 which is still positive,
but less so than from the shorter term forecast.
2 ,2..38'
ECONOMIC MONITORING REPORT
The economic monitoring report has documented a number of demographic and economic
indicators in an attempt to track the economic progress of the City and to forecast. where
possible, the economic future. Since this is the first attempt at a comprehensive economic
monitoring report. there may be certain indicators included that the GMOC does not wish to have
included in future reports. Likewise. there may be other indicators that have not been included
that the Commission may wish to see tracked in the future.
The work now being performed by the City's Community Development Department in support of
the newly created City Economic Development Commission should assist the GMOC's efforts at
providing forecasts of future economic development activities. Unfortunately. that work is now
only in its formative stages and has not been able to provide any concrete information that could
be included in this year's economic monitoring report.
The economic indicators that have been tracked show that the City's overall economic health
remained strong during the period between fiscal year 1988-89 and 1989-90. Taxable sales
transactions grew by 5.8% between the second quarters of 1989 and 1990. However, it should
be noted that the Chula Vista sales tax revenue per capita is still among the lowest in the county.
The assessed value of property within the City grew by 13.3% between fiscal year 1989 and
fiscal year 1990. while the residential building permit activity dropped significantly by
36.5% between calendar year 1989 and calendar year 1990. This latter reduction in building
permit activity is a reflection of the building slowdown resulting from a combination of the Otay
Water District's water allocation policy and the onset of the current recession during 1990.
Comparison of office and industrial building activity show that the amount of office space in the
City grew by some 88,000 square feet (+8.1 %) between the second quarter of 1989 and the
second quarter of 1990, with vacancy rates increasing from 2.1 % to 4.00%. Industrial space
grew by 566.901 square feet (+8.9%), while vacancy rates decreased from 6.3% to 3.9%. No
comparable information could be found for retail space within the City. However, the inventory
kept by Coldwell Banker Commercial Real Estate as of April 1991 showed a vacancy rate of
4.1 %. The continued strong demand for retail, office and industrial space reflected in these
figures has led to the somewhat high volume of non-residential projects that were seen in the
current twelve to eighteen month growth forecast discussed previously. It could be anticipated
that as these new projects build out, the City will see noticeable increases in vacancy rates as
the amount of non-residential space will exceed the demand until initial "lease up" of the new
3 ;l-!'
projects has occurred. How long this takes will depend to a large extent on the recovery from
the current recession, a factor the City has no control over.
The 1992 economic monitoring report will include comparative information from the detailed
results of the 1990 Census. This information will become available later this year and will
help in building an overall social and economic profile of Chula Vista of 1990 compared with
other cities in the region and with itself in 1980.

CITY OF CHULA VISTA GROWTH MANAGEMENT PLAN
YEAR 1990 TRAFFIC MONITORING PROGRAM
EXECUTIVE SUMMARY
1. BACKGROUND
In 1988 the City of Chula Vista adopted a Growth Management Plan. This plan was based
on a series of threshold standards regarding the operational aspects of the existing infrastructure on
a city-wide basis. The purpose of the Growth Management Plan is to assist the City of Chula Vista
in assessing the environmental, fiscal and operational effects of land developments. Traffic was
one of the elements included in this Growth Management Plan. The Year 1990 Traffic Monitoring
Plan (TMP) analysis is based on the current "Traffic Element" as shown on Table S-1.
In response to the adopted Traffic Threshold Standards, the City of Chula Vista Public
Works Department developed a request for proposal (RFP) to perfonn the initial Traffic
Monitoring Program for Year 1989. JHK & Associates (JHK) was retained by the City to conduct
this imponant monitoring project. To establish a more substantial data base, the City of Chula
Vista selected JHK to conduct a similar study for Year 1990. The primary focus of the Year 1990
TMP project was to again detennine the current operating condition of all signalized intersections
throughout the City. A study area map highlighting the location of the 109 project intersections for
the Year 1990 TMP is shown on Figure 1-1. This project also required an analysis of the existing
conditions at the 22 freeway ramp intersections on Interstate 5 and Interstate 805 within the City of
Chula Vista.
The following sections summarize the most critical elements of each of the topics addressed
during the completion of the Year 1990 Traffic Monitoring Program.
This Executive Summary is divided into the following sections:
1. Project Summary
2. Intersection Data Collection Summary
3. Summary of Signalized Intersection Performance
4. Summary of Freeway Ramp Intersection Performance
5. Conclusions and Recommendations - Year 1990 Traffic Monitoring Program

ADOPTED TRAFFIC ELEMENT
WAL:
To provide and maintain a safe and efficient street system within the City of Chula Vista.
OBJECTIVE:
1. Ensure timely provision of adequate local circulation system capacity in response to planned growth, maintain-
ing acceptable levels of service (LOS).
2. Plan new roadway segments and signalized intersections to maintain acceptable standards at build-out of the
General Plan - Circulation Element.
THRESHOLD STANDARD:

their current (1989) LOS. but shall not worsen.(p)
3. City-wide: No intersection shall operate at LOSE OfF as measured for the average weekday peak hour.(p)
Notes to Standards:
1. LOS measurements shall be for the average weekday peak hour. excluding seasonal and special circumstance
variations.
2. The measurement of LOS shall be by the ICU (Intersection Capacity Utilization) calculating utilizing the City's
published design standards.
3.Tbe measurement of LOS at signalized intersections of City arterials and freeway ramps shall be a growth
management consideration in situations wbere proposed developments bave a significant impact at inter-
changes.
4. Circulation improvements should be implemented prior to anticipated deterioration of LOS below established
standards.
IMPLEMENTATION MEASURES: .
Should the GMOC determine that the Threshold Standard is not being satisfied, then the City Council shall. within 60
days of the GMOC's report. schedule and hold a public hearing for the purpose of adopting a moratorium on the accep-
tance of new tentative map applications. based on all of the following criteria:
1. That the moratorium is limited to an area wherein a causal relationship to the problem has been established;
and.
2. That the moratorium provides a mitigation measure to a specifically identified impact.

2. INTERSECTION DATA COLLECTION SUMMARY
The City of Chula Vista Growth Management Plan identified 109 anerial intersections and
22 freeway ramp interchanges to be studied for the Traffic Monitoring Program. This project
required a minimal amount of data collections. Most of the intersection turning movement data was
obtained from the City of Chula Vista Traffic Engineering Division. For 20 of the 109 project
intersections, JHK was directed to collect field data as a supplement to the data provided by the
City. Data collection at these 20 critical locations was conducted during the fust two weeks of
February 1990.
To perform the intersection data collection effort, the JHK Project Team supervised a staff
of 8 to 12 trained temporary personnel. The data collection process consisted of manual turn
movement counts during three time periods: AM, Mid-Day, and PM. The AM, Mid-Day, and PM
count periods consisted of 2-hour counts (7:00 to 9:00 a.m., 11:30 a.m. to 1:30 p.m., and 4:00 to
6:00 p.m.). Data was recorded in 15-minute increments during the count period to ensure that
during the data reduction process the peak hour volumes could be determined accurately.
To aid in the data reduction, JHK developed a computer program to determine the peak
hour and perfonn intersection capacity analysis. The field data was input into the program and the
results were summarized for each period for each of the 109 project intersections. The Einal
Technical Report prepared by JHK in May 1991 contains a complete summary of all data collection
activities and technical analyses.
3. SUMMARY OF SIGNALIZED INTERSECTION PERFORMANCE
An important part of the City of Chula Vista Growth Management Plan was the accurate
determination of intersection capacities and Levels of Service (LOS). The Intersection Capacity
Utilization method simulates traffic operations of an intersection and typically summarizes the
operations by using ranges of LOS. LOS is simply a measure used to evaluate the operating
perfonnance of an intersection. LOS may range from A to F, with A being the best quality of
service and F the poorest.
Table S-2 summarizes the intersection capacity analysis findings for both Years 1989 and
1990 traffic monitoring programs. As shown on the table, the perfonnance of the signalized
intersections improved slightly from Year 1989 to Year 1990. This is due primarily to the
downward fluctuation in traffic volumes at specific arterial intersections during the peak periods, as
well as the implementation of new improved intersection geometries at critical locations within the
City of Chula Vista.

Summary Statement
In summary, of the 14 leu calculations which indicate poor levels of service, only 13
intersections are impacted. Upon close review of the summary information listed above, it is
apparent that all 13 impacted intersections operate in the LOS 0 or E range. Further review reveals
that five of these intersections actually QQ conform to Threshold Standard Number 1 based on the
fact that these intersections (No.'s 16,21. 61, 66, and 71) operate at LOS 0 for a period of less
than two hours per day.
Thus, the remaining six intersections: (No.'s 14, 18,34,62, 82 and 94) do not conform to
Threshold Standard Number 1 and funher analysis is required at these locations (see Standard
Number 2 below).

Year 1989 Data (Continued)
Summary Statement
The ICU analysis revealed that the eight intersections listed above, which are located in the
central portion of Chula Vista (West of 1-805), must be monitored closely to detennine if current
(Year 1989) levels of service deteriorate in the future. This is due to the fact that current operations
at these intersections result in extended periods of LOS D or E conditions.
· STANDARD NUMBER 3
- City-wide: No intersection shall operate at
LOS F as measured for the average weekday
peak hour.(P)
Statement of Conformance
The capacity analysis conducted by JHK revealed that no intersection operates at LOS F
during the average weekday peak hour.
It should be noted that the intersection of Hilltop Drive and H Street (No.82) is operating at
the threshold of LOS ElF. Thus. close monitoring of this intersection is warranted and as traffic
activity increases at this location in the future. geometric modifications may be required.

Summary Statement
In summary. the lCU calculations indicate that a total of seven intersections are impacted by
poor Levels of Service (LOS D or E). Further review reveals that six out of the seven intersections
actually dQ conform to Threshold Standard Number 1 based on the fact that these intersections
(No.'s 2.37.39,53.55. and 60) operate at LOS 0 for a period of less than two hours per day.
Thus, the remaining one intersection (No.7. Hilltop Drive and H Street) does not conform
to Threshold Standard Number 1 and further analysis is required at this location. (See Threshold
Standard Number 2 Analysis shown below.)

Summary Statement
As shown on the table above. the Year 1990 level of service for the intersection of Hilltop
Drive and "H" Street remained at LOS E. while the ICU at the intersection improved to 0.95 (Year
1990) from 1.00 (Year 1989). The primary reason for this changes in ICU was a reduction in

Year 1990 Data (Continued)
Year 1990 total PM peak hour intersection entering volume by approximately 6 percent.
Additionally, JHK tested this intersection with the provision of right turn only lanes on the
southbound and the eastbound approaches. As a result of this analysis, it is recommended that the
City Traffic Engineer install new striping for these movements to fonnally designate exclusive right
turn only lanes at this intersection.
· ST ANDARD NUMBER 3. City-wide: No intersection shall operate LOS E or
F as measured for the average weekday peak
hour.(P)
Statement of Conformance
The capacity analysis conducted by JHK revealed that none of the analyzed intersections in
the City of Chula Vista operate at LOS F during the average weekday peak hour for Year 1990
conditions. It should be noted that the intersection of Hilltop Drive and H Street is operating at
LOS E (0.96 ICU). Thus, close monitoring of this intersection is warranted and as traffic activity
increases at this location in the future, geometric modifications may be required as described in the
Threshold Standards Number 2 analysis presented previously.

THRESHOLD STANDARDS
The following statement summarizes the third element under the Notes to Standards section
of the Revised Traffic Element. The purpose for referencing this note is to allow City staff to
utilize the findings of this TMP study in the review of future development projects which impact
freeway interchange operations and ramp intersection levels of service.
Notes To Standards:
Note 3. The measurement of LOS at City arterials and freeway ramps shall be a growth
management consideration in situations where proposed developments have a significant
impact at interchanges.
Results of the Year 1990 review of the performance of signalized freeway ramp
intersections is summarized above. As shown on Table S-3, a total of five of the 11 freeway
interchanges located within the City of Chula Vista are impacted by poor levels of service (LOS E
or F conditions). Table S-3 identifies these five interchanges and the seven signalized ramp
intersections which are impacted.

5. CONCLUSIONS AND RECOMMENDATIONS
The study found that a limited number of intersections operate poorly during certain peak
periods. The peak hour analysis of traffic flow conditions at the 109 project intersections revealed
that a tot.a.l of seven locations experienced congested operations with levels of service ranging from
D to E. This compares with the Year 1989 Traffic Monitoring Program which reponed a tot.a.l of
13 locations experiencing congested operations with levels of service ranging from D to E. The
improvement in system performance in Year 1990 may be panially attributable to the connection of
SR 54 to 1-5 in December of 1990. The following list identifies the problem locations for Year
1989 and Year 1990 Traffic Monitoring Program Capacity Analysis:

Section S (Continued)
As was the case in Year 1989, all of these Year 1990 problem intersections are located west
of Interstate 805. This ponion of the circulation system is constrained by existing development
and the design of many of these older intersections were based on outdated standards. The
primary difficulty in this developed area of the city is the limited amount of right-of-way available
to construct additional turn lanes or throughways at many of these intersections. It is important to
recognize however, that the City Traffic Engineering depanment is in the process of reviewing all
City signalized intersections to determine the opportunity for providing additional exclusive right-
turn only lanes by restriping particular approaches to signalized intersections. Thus. in the future.
the City Traffic Engineering department will continue to implement improved geometric
configurations by restriping approaches to signalized intersections where opportunities exist.
The periodic monitoring of the performance of the transportation system within Chula Vista
is an important element of a well balanced growth management plan. Thus. it is further
recommended that all future traffic monitoring programs include the most critical intersections
(with peak hour operations of LOS C or lower) in both Central Chula Vista, west of Interstate 805,
and the newly developing areas east of Interstate 805 in the Eastern Territories. This will ensure
that conditions of these high-volume locations, which have existing levels of service approach in
the critical limits of the Threshold Standard, are analyzed on an annual basis. The periodic
monitoring process will allow the City to establish intersection level of service trends over time.
In conclusion. this Year 1990 report provides the City of Chula Vista with a Second
Annual Traffic Monitoring Program Data Base. Critical intersections have been identified and
potential mitigation has been discussed. The report presents a conservative estimate of intersection
operations based on the guidelines developed by the City of Chula Vista. The intent of this
document is to provide City staff with an indication of the current status of the overall circulation
system in terms of intersection capacities and levels of service. In the future, this report along with
the Year 1989 report, will be used as a tool for the accurate identification of existing traffic flow
conditions in the specific areas of the City where new development or redevelopment is occurring.
Also. this project accurately identifies "Hot-Spot" locations which warrant close attention in the
future.

6. REVIEW/CRITIQUE CURRENT LOS PROCEDURES AND TRAFFIC
THRESHOLD ORDINANCE
During the review of the Year 1989 Traffic Monitoring Program (TMP), the City Council
requested that the Year 1990 TMP funher examine the ICU technique for calculating capacity and
levels of service at signalized intersections as compared to the 1985 Highway Capacity Manual
(HCM). Also raised as an issue by the City Council was the question of an appropriate method for
detennining future impacts from proposed developments. "acceptable" levels of service. and what
should be the horizon year for traffic impact studies. These issues associated with future planning
are discussed in detail in Section 8.
Review/Critique Current LOS Procedures
. ICU (Intersection Capacity Utilization) - A "shon-cut" procedure to manually determine
the cri tical V IC ratio.
· 1985 HCM - The 1985 HCM completely redefines LOS as a function of vehicle
"Stopped Time Delay."
In addition to the new LOS definition. the 1985 HCM also provides an equation for the
direct calculation of delay based on the following factors:
· Volume
· Saturation Flow Rate
· Lost Time
· Cycle Length
· Phase Time
· Progression
· V IC Ratio
· Green Ratio
. The actual delay equation is quite complex. However, the personal computer negates the
complexity, and funher, the computer allows programming of the equation such that it becomes
very easy and quick to do much more engineering of signalized intersections than has ever been
possible previously.

Comparison of Year 1989 and Year 1990 Capacity Analysis - HCM Methodolol:Y
To understand how these two capacity analysis techniques apply to conditions in the City
of Chula Vista, JHK conducted a comparison of ICU and HCM on the 13 most critical
intersections within the City of Chula Vista. The 13 critical intersections were identified in the
Year 1989 TMP. Table S-4 summarizes the results of this comparison. As shown on Table S-4,
the HCM (Delay) method typically predicts a lower LOS as compared to the ICU method

Section 6 (Continued)
However, it is recognized that exceptions exist, and each intersection is unique. Thus, the
following findings and recommendations are presented.
Research conducted by the national Transportation Research Board (TRB) and accepted by
the TRB Committee on Highway Capacity and Quality of Service indicated that the detennination
of LOS based on capacity did not adequately represent signalized operations. The TR.B determined
that the intersection volume-capacity (V IC) ratio had the least impact upon LOS of signalized
intersections and that signal timing, progression, and cycle lengths had the greatest impact.
Therefore, low V IC ratios did not necessarily indicate good levels of service, and high V Ie ratios
did not necessarily indicate poor levels of service.
The basis of level of service was found to be best represented by ~elay and was agreed
upon by the TRB committee. It is recognized that the existing practice of calculating capacity and
level of service within the region is inconsistent with the research conducted nationally and does
not agree with the definition of level of service as accepted by ITE, TRB, and the FHW A, except
for those agencies which have already adopted the delay based definition for level of service.
The Year 1990 TMP recommends the use of the Delay Methodology, as defined in the
1985 Highway Capacity Manual, as an area-wide uniform method to perform Capacity and Level
of Service analysis of signalized intersections. We found this method to best reflect observed
signalized operations, as well as to conform to the national definition of level of service. The leU
should continue to be used in the calculation of capacity utilization, but should not be related to
level of service.
Applying the delay definition of LOS and the recommendation of acceptable LOS would
greatly enhance the quality of impact studies and address our regions' growth in a responsible
manner as well as meeting the requirements of regional Quality of Life Standards, Congestion
Management Program goals, and Air Quality legal mandates.
· Delay methodology provides the best available tool for analyzing signalize intersections
and can be easily used for both planning and operational analysis.
· Other methodologies define Level of Service by inconsistent criteria which cannot be
correlated with the delay definition.
· Software is presently available to allow quick and easy application of the delay
methodology.
Therefore, based on this review there should be only one definition of LOS and it should
be based on the 1985 HCM. As a result of this recommendation all future Traffic Monitoring
S-17 ~ -5'
Section 6 (Continued)
Programs and Traffic Impact Study Repons will be required to utilize the HCM Delay
methodology for calculating intersection levels of service and system performance.
Review/CritiQue Traffic Threshold Ordinance
As requested in the RFP for the Year 1990 TMP, JHK performed a review/critique of the
current traffic threshold ordinance adopted by the City of Chula Vista.
As a result of the review, the following recommendations are provided for consideration by
the City of Chula Vista:
. Conduct Average Weekday Peak Period (AM, Mid-Day, PM) Travel Time Studies on a
System-Wide Basis.
. Prepare Network Performance Graphics with Observed Speeds and LOS.
. Collect and Analyze Peak Period Turning Movement Data at Critical Intersections.
. Utilize HCM Methodology to Establish LOS Findings.
. Modify Current Threshold Standards to Conform to HCM Methodology and LOS
Calculations.
These recommended modifications to the current TMP process have been designed to
provide a more realistic indication of network performance and an accurate reflection of observed
conditions at signalized intersections. Also, this methodology conforms with the national
definition of level of service and JHK believes that applying the delay definition of LOS would
greatly enhance the quality of the Traffic Monitoring Program.
Recommended Reyisions to Traffic Element
Revisions to the adopted "Traffic Element" of the Growth Management Plan were
developed through consultation with City staff. These recommended Year 1990 revisions are
intended to reinforce the goals and objectives of the current "Traffic Element". Table S-5 presents
the revised "Traffic Element" as approved by the Growth Management Oversight Commission at
their meeting on May 23, 1991. A more detailed discussion of the revised "Traffic Element" is
contained in the Final Report prepared by JHK in June 1991. Figure S-3 shows the recommended
anerial analysis network to be used in conducting the Year 1991 Traffic Monitoring Program.

CITY OF CHULA VISTA GROWTH MANAGEMENT PLAN
REVISED TRAFFIC ELEMENT - MAY 1991
GOALS
· To provide and maintain a safe and efficient street system within the City of Chula Vista.
· To establish a performance measurement methodology enabling the City to accurately
detennine existing levels of service for motorists.
· To define a level of service value that represents a high quality of traffic flow under constrained
operating conditions during peak periods of traffic activity.
· To establish a performance standard which is consistent with the Regional Growth
Management Standards.
· To maintain consistency in terms of LOS ratings between the previous ICU methodology.
OBJECTIVES
1. Ensure timely provision of adequate local circulation system capacity in response to planned
growth, maintaining acceptable levels of service (LOS).
2. Plan new roadway segments and signalized intersections to maintain acceptable standards at
build-out of the General Plan Circulation Element
THRESHOLD STANDARDS
· City-wide: Maintain LOS "C" or better as measured by observed average travel speed on all
signalized arterial segments except that during peak hours LOS of "0" can occur for no more
than any two hours of the day.
· West of 1-805: Those signalized anerial segments which do not meet the standard above, may
continue to operate at their current (Year 1991) LOS, but shall not worsen.
Notes to Standards
.
Anerial segment LOS measurements shall be for the average weekday peak hours,
excluding seasonal and special circumstance variations.
.
Urban and suburban arterials are defined as surface highways having signal spacing of less
than two miles with average weekday traffic volumes greater than 10,000 vehicles per day.
Anerial segments are stratified into the following three classifications as shown on the
attached graphic:
Class I anerials are roadways where free flow traffic speeds range between 35 mph and 45
mph. and the num~r of signalized intersections per mile are less than four. There is no
parking and there IS generally no access to abutting property.

Class II anerials are roadways where free flow traffic speeds range between 30 mph and 35
mph, the number of signalized intersection per mile range between four and eight, there is
some parking and access to abutting properties is limited.
Class III arterials are roadways where free flow traffic speeds range between 25 mph to 35
mph and the number of signalized intersections per mile are closely spaced. There is
substantial parking and access to abutting property is unrestricted.
· The LOS measurements of arterial segments at freeway ramps shall be a growth
management consideration in situations where proposed developments have a significant
impact at interchanges.
· Circulation improvements should be implemented prior to anticipated deterioration of LOS
below established standards.
· The criteria for calculating arterial LOS and defining arterial lengths and classifications shall
follow the procedures detailed in Chapter 11 of the 1985 HCM and shall be confmned by
the City Traffic Engineer.
· During the conduct of future TMP traffic field surveys, intersections experiencing
significant delays will be identified. The infonnation generated by the field surveys will be
used to detennine possible signal timing changes, geometric and/or traffic operational
improvements for the purpose of reducing intersection delay.
· Level of service values for arterial segments shall be based on the following table:
Level of Service Average Travel Speed (MPH)
Class l Class 2 Class 3
A ~ 35 ~ 30 ~ 25
B ~ 28 ~24 ~ 19
C ~ 22 ~ 18 ~13

Research Board, National Research Council, Washington, D.C., 1985.
Imolementation Measures
· Should the GMOC detennine that the Threshold Standard is not being satisfied, then the
City Council shall. within 60 days of the GMOC's repon, schedule and hold a public
hearing for the purpose of adopting a moratorium on the acceptance of new tentative map
1. That the moratorium is limited to an area wherein a causal relationship to the problem
has been established; and,
2. That the moratorium provides a mitigation measure to a specifically identified
impact.

7. "H" STREET CORRIDOR ANALYSIS
This chapter was developed to address traffic concerns expressed the City Council at their
August 30, 1990, meeting during discussions growth management, directed staff to report on
impacts of Eastern Territories Area Growth and Development on existing and future traffic
volumes on "H" Street west of Interstate 805. Also, on March 5,1991, the City Council directed
staff to examine the impact of increased development within the "H" Street corridor between Third
A venue and Interstate 5. Related to the impact of Eastern Territories Planning Area developments
on "H" Street is the action taken by the City Council on July 11, 1989, designating "H" Street
between Hilltop Drive and Third Avenue as a four-lane major street When the Final General Plan
Circulation Element was presented to the City Council, staff recommended that "H" Street be
classified as a six-lane major street, continuously, between I-80S and 1-5. The six-lane
classification was based on forecasted volumes resulting from the implementation of the adopted
General Plan Land Use Element.
To address the Eastern Territories Planning Area traffic impact issue and the "H" Street
four lane designation issue, staff has performed an initial traffic evaluation of existing and future
traffic conditions on "H" Street west of I-80S. The findings of this traffic evaluation report are
intended to provide the City Council with: (1) the relationship between growth and development
in the Eastern Territories Planning Area ,and resultant traffic activity on "H" Street; and (2) to
document the importance of redesignating "H" Street between Hilltop Drive and Third Avenue as a
six-lane major street.
Conclusions
1. Existing roadway capacity on "H" Street (for four lanes) adequately serves current travel
demand with the exception of poor level of service at "H" Street and Hilltop Drive
during the PM peak hour.
2. The interaction of trips resulting from current and future Eastern Territories Planning
Area development contributes significantly (in excess of 50 percent of traffic activity on
"H" Street west of 1-805 in Years 1990, 1995 and buildout).
S-22 ~ -~ 4/
3. The remaining buildout of the Eastern Territories Planning A;-ea represents a srnnller
share of all traffic (52 percent) than what exists today (56 pcrcer.t) on "H" Street west of
1.805. However. it is recognized that this contribution is still significant in the long-term
(forecasted to be in excess of 50 percent).
Recommendations
"H" Street Roadway Classification - Six Lane Implementation Policy
Near-Term Measures
. Focus future geometric improvements at signalized in:e'rsections where impediment to
traffic flow are greatest. This measure may forestall the need for rnid-block widening.
. Prohibit on street parking along critical mid-block sefments to increase capacity and
improve traffic flow.
Lont:-Term Measure
. Study a General Plan Amendme.nt for a for six-lane facility. This would enable staff to
extract adequate rights.of-way in the future as a condition of development.
. Adopt a minimum roadway width standard to minimize. impacts of future widening on
adjacent properties.
. For segments West of Fourth Avenue. the City shall require roadway widening in
addition to right-of-way dedication to implement the modified roadway width standard
as a condition of development.
· For the segments East of Fourth Avenue the City may defer mid-block widening and
focus on improving intersection capacity.
The Final Report prepared by JHK in May, 1991 contains a complete discussion of all issues
related to the "H" Street Corridor Analysis.

8. ANALYSIS OF EASTERN TERRITORIES GROWTH IMPACTS
As requested by the Growth Management Oversite Committee JHK has prepared an
analysis of Eastern Territories growth impacts on existing transponation facilities with the Central
Chula Vista area west of Interstate 805. The three most critical links identified by the Growth
Management Oversite Committee for review during the 1990 Traffic Monitoring Program process
were "H" Street. "L" Street. and Palomar Street.
"R" Street Analvsis
The segments approaching the intersection of Hilltop Drive and "H" Street were selected
for review. These segments are representative of segments west of Interstate 805 which are
impacted by Eastern Territories growth and traffic activity.
The roadway system adjacent to the intersection of Hilltop Drive and "H" Street
experienced a reduction in traffic activity primary in the east/west direction do to the relief provided
by the opening of State Route 54 between Interstate 805 and Interstate 5 in December 1990. Year
1991 counts indicate an approximate reduction of 6 percent in the east/west volume activity along
"H" Street near the intersection of Hilltop Drive and "H" Street A corresponding improvement in
intersection Level of Service was identified a Hilltop Drive and "H" Street (Year 1989 - ICU 1.00.
LOS E and Year 1990 - ICU 0.95, LOS E).
"L" Street Analvsis
In addition to the "H" Street segments. the segments approaching the intersection of Hilltop
Drive and "L" Street have been impacted by Eastern Territories Growth and traffic activity. Both
east/west and nonh/south segments approaching the intersection of Hilltop Drive and "L" Street
showed a significant decrease in ADT volumes after the opening of State Route 54 between
Interstate 805 and Interstate 5. As described within the "H" Street analysis. volumes decreased
due to the diversion of east/west traffic to the recently opened State Route 54. Traffic along "L"
Street has also decreased due to the completion of this alternative route as well. A corresponding
improvement in intersection Level of Service was identified at Hilltop Drive and "L" Street (Year
1989 - ICU 0.84, LOS D and Year 1990 - ICU 0.80. LOS C).
An increase in the utilization of State Route 54, which connects Interstates 805 and 5 would
also explain the decrease in nonh/south ADT volumes at the intersection of Hilltop Drive and "L"
Street.

Section 8 (Continued)
Palomar Street Analvsis
At the present time there are no development projects in the Eastern Territories Planning
Area that induce measurable travel within the Orange AvenuelPalomar Street Corridor. Traffic
studies for proposed Eastern Territories developments indicated that the orientation of the majority
of trips generated from these Eastern Territories projects is primarily nonh/south along Interstate
805. Future growth in traffic activity along Palomar Street will occur as a result of infill
development within the Montgomery Cormnunity and surrounding area west of Interstate 805.
It is important to note that an Environmental Impact Report (EIR) has been prepared for the
Proposed Palomar Trolley Center Project to determine future impacts within the corridor. This
EIR Traffic Study is an example of the circulation improvement requirements that will be mandated
on future development projects to assure that the cumulative effect of traffic growth is mitigated
IItR' 'luately.
9. PROCEDURAL GUIDELINES FOR PREPARING TRAFFIC IMPACT STUDY
REPORTS
It is recommended that the Delay Methodology, as defined in the 1985 Highway Capacity
Manual. be used as an area wide uniform method to perform Capacity and Level of Service
analysis of signalized intersections. This method best reflects observed signalized operations.
Delay methodology conforms to the national definition of level of service and is the methodology
recormnended for the San Diego regions' traffic Congestion Management Program. The ICU
should continue to be used in the calculation of capacity utilization, but should be limited to the
cursory examinations of future development planning. The preliminary recormnendations is to
require a minimum intersection LOS of "C" for all new development projects. Traffic mitigations
for new development should be required to achieve the minimum LOS. In such cases where the
existing LOS is substandard, mitigation by a private party should be such that the LOS is at least
maintained and the intersection V Ie ratio not increased; thereby. the impacted intersection is not
made worse.
