5. Byron Utility Analysis Update
Beth Lee reported that a Federal Aviation Administration (FAA) grant was received to perform the
infrastructure analysis and to design pavement, lighting and signage enhancements.
The infrastructure analysis is in its final stages and should be completed in the next 30 to 45 days. The
results will be used to start the General Plan amendment process for the Byron Airport.
Supervisor Piepho reported that there are plans to expand Clifton Forebay before more water starts being
sent to Southern California.
Supervisor Piepho suggested that Airport staff look over the Environmental Impact Report (EIR)
on the project to see how the expansion will affect the Airport.
o Supervisor Mitchoff commented that the EIR is due out in mid to late October and that
there would be a 120 day response period.
Supervisor Piepho commented that the expansion could have impacts on the Byron Airport like
runway lengths, infrastructure and wildlife.
6. FAA Funding Application for Buchanan Field Wildlife Hazard Assessment Update
Keith Freitas reported that every year an FAA Certification Inspector does an inspection of Buchanan
Field as the Part 139 Commercial Certificate has been maintained.
All airports with Commercial Certification are required to update wildlife hazard assessments.
Although Buchanan Field does not have any particular issues; FAA grant money was received to
have a new assessment performed.
o The assessment will start on or about October 1, 2013, and will take about 13 months to
complete.
o A final report will be completed which will identify potential hazards and things that can
be done to mitigate them.
7. Airport Fiscal Year (F/Y) 2012/13 Budget at 99%
Keith Freitas reported that the Airport met its revenue target at 103% and expenses came in at 92% of
budget.
Capital Projects still need to be funded
o Painting of hangars
o Pavement repairs and replacement
Recommendation was made to add $60,000 to the Airport Reserve Fund (Fund) bringing the
fund total to $400,000.
o Fund balance would then be consistent with County policy and the Fund policy.
o Supervisor Mitchoff requested a copy of the F/Y 2013/14 budget be forwarded reflecting
the Fund change. Footnote changes that note costs of funds dedicated from the Mariposa
Community Benefit Fund ($800,000).
Supervisor Piepho asked if any of the Mariposa Community Benefit Fund (MCBF) monies had been
used.
Keith Freitas stated that the monies would be pulled when projects are complete.
Supervisor Piepho asked to have footnotes added to the F/Y 2013/14 budget reflecting the
projects and amounts of the MCBF that have been allocated.

1. Introduction
The Contra Costa County Airports Division is planning for development of the Byron Airport (Airport) as
permitted under the Byron Airport Master Plan. As part of planning the Airport development, the existing
utilities will need to be upgraded to serve the additional development areas. The Airport is currently
served by a fire protection system consisting of a 3,000 gallons per minute (gpm) fire pump and a pipeline
system with 20 fire hydrants. The sanitary sewer system consists of approximately 2,500 linear feet (LF)
of sanitary sewer collection main, a 3,000-gallon septic tank, lift station, and drain field. The domestic
water system consists of a groundwater well, chlorine feed system, 4,000-gallon storage tank and booster
pump, and approximately 2,000 LF of small diameter distribution mains.
The purposes of this study are to evaluate capacity limits for the existing fire protection system, sanitary
sewer system, and domestic water system to determine capacity remaining in the systems to
accommodate development; identify and analyze necessary infrastructure improvements needed for
development; and to prepare cost estimates and an implementation plan to upgrade the systems
mentioned above for full build-out of the Byron Airport Master Plan. The Airport Layout Plan (ALP) is
included in Appendix A.
In addition, a general review of the private utilities and storm drainage system at the Airport has been
included in this study.
1.1 Airport History
From the Contra Costa County website:
Studies carried out by Contra Costa County in the late 1970's / early 1980's identified the need for
one or more airports in the County to relieve the aircraft parking and operational pressures on
Buchanan Field Airport in Concord. Continued urbanization in the western and central sections of the
County made it impossible to develop a new airport in those areas. The County then focused its
attention on finding a site for a new airport in the eastern part of the County. The East Contra Costa
County Airport Master Plan completed in May 1986 was the third of three documents prepared as
part of the East Contra Costa County Airport Site Study, the others being the Phase 1: Site
Identification and Evaluation (October 1984) report and the Environmental Impact Report: East
Contra Costa Airport (Draft, September 1985; responses to comments, January 1986). Preparation
of an Airport Layout Plan for the Byron site and assessment of the environmental impacts of airport
development at Byron were presented in the Environmental Impact Report (EIR). The EIR was
reviewed by governmental agencies as well as the general public, responses to comments were
prepared, and the document was subsequently certified by the County Planning Commission.
The site evaluation culminated in the County Board of Supervisors' selection of the Byron Airpark (a
small privately owned airport located in the southeastern area of the County) to provide aviation
facilities for the residents of East Contra Costa County. The Byron Airpark was purchased in 1986,
and the new airfield constructed in the early 1990's. The new Byron Airport was opened to the public
2
X:\4186500\121867.00\CORR\Rpts\Byron Airport Infrastructure Study Report.doc
in October 1994, replacing the Byron Airpark that occupied the northwest corner of the current airport
property. The Airport is 1307 acres with the majority (814 acres) of the land reserved for Habitat
Management Land for a variety of endangered and special status species of mammals and plant life.
2. Byron Airport Master Plan Potential Development
The main goal of the 2005 Airport Master Plan (AMP) was to provide land use guidelines which satisfy
future aviation demand. The 2005 AMP provides an evaluation of the Airport’s aviation demand and an
overview of the systematic airport development that will best meet those needs. Land use guidelines are
established in the 2005 AMP for future airport functions, including general aviation, airport support,
aviation-related land uses, and non-aviation land uses. The 2005 AMP categorized the potential future
land development into two categories; near-term aviation-related land uses and long-term aviation-related
land uses.
From the Executive Summary of the 2005 AMP, regarding development at the Airport:
• Cargo development at Byron Airport would be expected to follow a development cycle. Large air
cargo aircraft operations are unlikely in the next 10 to 15 years, and likely Airport activities in the
short-term will result from trucking activity and the Airport’s relationship to other airports. Feeder (or
propeller) aircraft represent the most likely source of initial air cargo activity and incremental growth at
the Airport, building on trucking activity.
• Regional economic trends will likely support aviation growth. The eastern section of Contra Costa
County, in which the Airport is located, has experienced growth in residential and industrial
development as population and business activity force new development outside more developed
areas of the East Bay (specifically, Alameda County). This trend is expected to continue in the long-
term. Diversified regional development, including office, light industrial, warehousing and logistical,
and residential development would likely facilitate economic and aeronautical growth.
• The Bay Area’s general aviation market has a long-term need for facilities. Corporate aviation has
been and is expected to be one of the fastest growing general aviation market segments, and is
expected to spur demand for aircraft hangar storage and for the fixed base operators that support
such corporate activity.
• The major factors that will affect the potential development of air cargo and general aviation are
external to the Airport. There is currently a low concentration of “cargo-generating” business and a
low concentration of population and business relevant to general aviation, surrounding the Airport.
Improvements of the regional road and highway network would also be needed.
• Developments on-Airport could support and enhance regional development and the potential for air
cargo and general aviation. Incremental development of general aviation and specialty aviation
activity at Byron Airport would attract and facilitate aviation support services useful to potential air
cargo feeder operators. Incremental development of non-aeronautical property at Byron Airport
3
X:\4186500\121867.00\CORR\Rpts\Byron Airport Infrastructure Study Report.doc
would assist in generating sufficient local business activity that could support air cargo development,
including office and light industrial parks and distribution centers.
Boundaries on land use areas are determined by setbacks and clearances required by the Federal
Aviation Administration (FAA) standards to facilitate the safe and efficient operation of the airport. Based
upon the required setbacks and clearances, developable areas of property were defined.
2.1 Setbacks and Clearances
Setbacks and clearances from runways and taxiways are required for multiple reasons, most importantly
to maintain safety margins that allow for safe and efficient airfield operations. Setbacks and clearances
are also established to limit growth in areas where the airport may expand aeronautically in the future
(such as runway expansion or instrument approaches) and for aviation related or non-aviation
development.
Safety areas illustrated on the airport layout plan (ALP – See Appendix A) of record are typically used to
determine setbacks to building and development areas. Multiple areas and zones are illustrated on an
ALP that limit certain types of land use or activity in an area. These critical areas are determined by
various factors such as the critical aircraft, wingspan and wingtip clearances, and visibility minimums and
instrument approaches.
2.1.1 2013 Airport Layout Plan
FAA regulations and design standards specify critical area dimensions and setbacks on an ALP be based
on design aircraft, instrument approach minimums and other factors detailed in various Advisory Circulars
(AC). Some of the most prevalent ACs are AC 150/5300-13A: Airport Design and Federal Aviation
Regulation Part 77: Safe, Efficient Use, and Preservation of the Navigable Airspace.
The ALP for Byron uses FAA guidance to determine the appropriate safety areas and critical setbacks for
Byron Airport. The ALP is being updated concurrently with this Infrastructure Study, and is referred to as
the ‘2013 ALP’ in the balance of this Study. As of this writing, the 2013 ALP is in a draft state and has
been reviewed and accepted by the Airport to be used as part of this Study, but has not yet been
approved by the FAA. The 2013 ALP is being updated to conform to new FAA guidance on ALP
preparation. Land use shown on the current ALP reflects the vision of the Airport from the approved
Master Plan. Critical safety areas are detailed on the 2013 ALP.
2.2 Ultimate Land Use
The 2013 ALP set contains a Land Use Map that details future land use areas and acreages. The Land
Use Map was edited using the 2005 Airport Master Plan as a guide and revised based on Airport staff
input and current FAA standard for critical areas and setbacks. Land Uses are illustrated in Exhibit 1.
4
X:\4186500\121867.00\CORR\Rpts\Byron Airport Infrastructure Study Report.doc
2.2.1 Land Use Designations and Calculations
Definitions for each land use:
• Airport Related Use – Land that is designated for aviation or non-aviation uses. Any non-aviation
use may require FAA approval and release of land.
• Aviation Reserve – Land that is reserved for uses that would be directly related the airport and
aeronautical functions.
• Aircraft Storage – Area allocated for aircraft storage hangars near the existing building area. This
area is outside of the BRL.
• Aircraft Parking – Land near the existing building area that is set aside for outdoor aircraft
parking. This area is between the BRL and the OFA.
• Low Intensity Use – Land that is open space but may offer potential land use in the form of
agriculture, as long as it does not attract birds or other wildlife that may interfere with airport
operations. These areas need to be free of structures but may offer some revenue generating
use.
• Habitat Management Land – Property designated for open space.
The following table provided acreages for each land use. See Exhibit 1 for more clarification.

Aircraft Parking West of Runway 12-30 (Existing Building Area) 9.7
Low Intensity North and East of Runway 12-30 39.0 48.9 Runway 23 Approach – Runway Protection Zone 8.9
Habitat Management Land 810.6
Areas east of Runway 12-30 that are bisected by irrigation canals are not included in acreages for
potential land use. A large irrigation canal (Byron Bethany Irrigation District 45 Canal) traverses much of
the northeastern development area and a large detention basin is sited on a portion of the eastern area.
These facilities and their associated setbacks further reduce the availability of developable sites within
5
X:\4186500\121867.00\CORR\Rpts\Byron Airport Infrastructure Study Report.doc
these areas. In addition, existing and proposed roads and right-of-ways are also excluded from land use
calculations.
Eighteen acres east of Runway 5-23 is not considered available for major development since it is located
at the extension of the runway and is currently used as a storm drainage detention basin. The detention
basin may be expanded to allow for future development. Refer to Section 7 below for storm water
evaluation.
2.2.2 Development Phasing
According to the 2005 Airport Master Plan, two terms of phasing development are proposed: near- and
long-term. Phasing is illustrated on Exhibit 1 and only applies to areas where future potential building
development is possible (Airport Related and Aviation Reserve land uses).
According to the 2005 Master Plan, the near-term planning scenario was meant to correspond a time
frame from 2008-2010. However, since the near-term time frame has passed as of the date of this report,
the updated near-term time frame is from 2014-2019. The near-term development area is located west of
the intersection of the two runways, and is reserved for general aviation and airport support (See Exhibit
1). A total of 56.8 acres are designated for near-term development. In order to facilitate movement of
ground vehicles and to maintain runway approach and safety requirements, it is recommended that
Falcon Way be upgraded and extended to provide access to these areas as part of near-term
development.
The 2005 Master Plan projects the long-term planning scenario from 2023-2025. However, since the
near-term time frame has passed as of the date of this report without development, the updated long-term
time frame is from 2020-2029. The long-term development areas are located north and east of Runway
12-30 and immediately north of Runway 5-23 (See Exhibit 1). The area designated for long-term
development totals 96.7 acres.
3. Fire Protection System
3.1 Existing Fire Protection System
The existing fire protection system consists of approximately 11,000 feet of pipeline and 20 hydrants, and
is supplied by a 100-horsepower (HP) fire pump which is located in a pump house on the northeast side
of Runway 12-30. The Airport is required to maintain the capacity to fight the design fire which includes a
total fire flow of 3,000 gpm, supplied from three hydrants flowing simultaneously at 1,000 gpm each for
three hours with 20 pounds per square inch (psi) residual pressure in the main. The duration of the
design fire is three hours. The minimum requirement is to provide water storage and pumping capacity
for one design fire.
The existing fire pump has a design pumping capacity of 3,000 gpm. The fire protection system was
designed for three hydrants flowing simultaneously for three hours with 20 psi residual pressure in the
main. The fire pump is supplied by a lined fire protection pond which receives water from the Byron
6
X:\4186500\121867.00\CORR\Rpts\Byron Airport Infrastructure Study Report.doc
Bethany Irrigation District (BBID). There is also a siphon pump station located southeast of the runway
intersection that provides water from an underground 96-inch diameter pipe as a supplement to the fire
water pond.
In order to provide enough water to meet the fire protection system requirements, the pond requires a
minimum capacity of 540,000 gallons. The lined pond has been estimated to contain a storage capacity
of approximately 750,000 gallons based on the construction record drawings. Approximately one million
additional gallons of water is available from the 96-inch diameter pipe. The 96-inch diameter pipe is
approximately 3,200 feet long and is a section of the BBID Canal 45, which was piped underground for
development of the Airport. During irrigation season when the BBID canal is in operation, typically May
through October, the pond may be refilled as needed and there is no limitation to water supply for fire
protection. Outside of irrigation season, the supply of water available for fire protection is limited to the
storage within the pond and 96-inch diameter pipe; however, the BBID is willing to assist the Airport in
providing water for fire suppression in an extreme fire event where the pond and 96-inch diameter pipe
are depleted.
Based on available storage capacity, the Airport currently has sufficient storage to fight approximately
three design fires outside of irrigation season and no limit during irrigation season. The fire pump has the
capacity to fight one design fire at a time, which meets current requirements.-
The Airport has been experiencing difficulties with the fire pump and has had to replace it twice in recent
years. The fire pump is currently operating without any reported issues. The fire pump does not have an
on-site back-up system; however, the County owns a trailered unit that can be driven to the site if the fire
pump fails.
3.2 Existing Fire Protection System Capacity
The existing fire protection system was modeled using WaterCAD Version 8i developed by Bentley
Systems, Inc. The WaterCAD program is a design tool used to model water supply systems and
calculates how much flow is available at any hydrant or group of hydrants in the system, based on supply,
pressure and flow constraints. Fire flows were simulated near the western end of Runway 12-30 because
hydrants at this location are furthest from the fire pump. The modeling assumed that adequate water
storage was available for the duration of the fire, and that the fire pump is performing as indicated on the
manufacturer’s pump curve. The results of the model confirmed that the fire protection system is capable
of supplying three hydrants simultaneously with a flow of 1,000 gpm each for three hours, while
maintaining a minimum of 20 psi residual pressure in the water main pipeline. The WaterCAD model
report is included in Appendix C. The existing system meets the current fire protection requirements of
the Contra Costa County Fire Protection District and the National Fire Protection Association.

3.3 Fire Protection System for Potential Development
3.3.1 On-Site Fire Protection System
As discussed in this section, the existing fire pump is capable of supplying water for fire protection for the
near-term and long-term future development. The fire protection system extensions required to service
the near-term and long-term future development connects to the existing system and is shown on the
Utilities Plan in Appendix D. The near-term and long-term fire protection improvements include
approximately 9,100 feet and 12,600 feet of 12-inch pipeline, respectively, to serve the development
areas. The pipeline extensions would provide a looped system to maintain pressure in the pipeline,
extend fire protection to all areas, and add flexibility of water delivery if sections need to be isolated for
maintenance.
The fire flow requirements are based on the 2010 California Fire Code (Part 9 of the Title 24, California
Code of Regulations (CCR). Future code updates may require changes to the fire flow requirements.
The future fire protection system was modeled using WaterCAD to verify adequate volumes and pressure
of water for fire protection and to verify pipe sizing for the future pipelines. The fire protection pipeline
was assumed to be 12-inch PVC, which matches the existing system pipes, and fire hydrants were
modeled at maximum 500-foot spacing. The model simulated the fire along Runway 5-23 because this is
the most remote part of the future system and is not fully looped. The results of the model concluded that
the existing fire pump is capable of supplying water to three hydrants simultaneously with a flow of 1,000
gpm each, while maintaining a minimum of 20 psi residual pressure in the water main pipeline for the
near-term and long-term developed condition, as shown on the Utilities Plan.
3.3.2 Discovery Bay Water System Connection
The Discovery Bay Community Services District (CSD) completed their water system Master Plan update
in January 2012. Extending water service to the Airport was not anticipated in the Plan; however, the
CSD does have capacity in their system to provide water for domestic and fire protection uses. In
discussions with the CSD, sufficient capacity is currently available and the CSD would be open to
discussions on serving the Airport. However, it should be noted that the CSD’s obligations may change,
so there is no guarantee that there will be capacity in the future if/when the Airport would want to connect
to the CSD system. In addition, since the Airport and pipeline route are outside of Discovery Bay’s
service boundaries, the connection would have to be approved by the Contra Costa Local Agency
Formation Commission (LAFCO). It is not known at this time if local residents or property owners along
the pipeline route would support or oppose the project.
The assumption made for cost estimating purposes is that the Airport would be responsible for all costs
associated with the connection to the Discovery Bay System, which is likely to include a water storage
tank, pipelines, a water booster pump station, and easements. Refer to Appendix E for a map of a
proposed alignment for a utility connection to Discovery Bay, and Appendix F for an on-site Utility Plan
with a Discovery Bay connection. As shown on the Utility Plan, the domestic water and fire protection are
combined in a single water main.

3.3.3 Byron Water System Connection
The community of Byron does not have a domestic water system. The residents primarily rely on
individual domestic water wells. There is a small community water system with two wells located along
Main Street, but the system has insufficient capacity to provide water to the Airport.
3.4 Opinion of Probable Construction Costs (OPCC)
A comparative opinion of probable construction costs (OPCC) was developed for the fire protection
system improvements required to support future development. The OPCC only included the major
construction components for each scenario. Unit costs were estimated using the RS Means Heavy
Construction Cost Data Manual 2013, Contractor bids for related work, and discussions with
contractors/suppliers.
3.4.1 On-Site Improvements
An OPCC was prepared for extending the existing fire protection system to the near-term and long-term
potential development areas. Since the existing fire pond and pump have the capacity to support the
development areas, only pipeline extensions were required for the future areas. The OPCC’s for the
near-term and long-term development are provided below.
The near-term developments include extensions of the fire protection system to serve the development
areas along the west side of Runway 12-30.

The long-term developments include extensions of the fire protection system to serve the development
areas along the northeast side of Runway 12-30 and immediately north of Runway 5-23 to provide a
looped system. The long-term improvements assume that the near-term improvements have already
been constructed.

3.4.2 Connection to Discovery Bay
An OPCC was prepared connecting to the Discovery Bay water system for fire protection for the existing
developed areas and the near-term and long-term potential development areas. The alternative included
a transmission main from Discovery Bay, a water storage tank, and a booster pump station. The costs for
the connection to Discover Bay would be included in the near-term development costs, and the long-term
development OPCC only included on-site pipeline extensions to the development area since it is
assumed that the water transmission from Discovery Bay, booster pump station, and water storage tank
were already constructed for the near-term development area. The OPCC’s for the near-term and long-
term development are provided below. Since the size of a water transmission pipeline for a joint-use of
fire protection and domestic water is governed by the fire flow demand, this alternative also includes
providing water service for domestic and irrigation uses.

4. Sanitary Sewer System
4.1 Existing Septic System
The Airport’s sewer service is currently provided by approximately 2,500 LF of sanitary sewer collection
mains and a 3,000-gallon underground septic tank with a lift station to a leach field that is located
southwest of the main aircraft ramp. The lift station includes two 2-HP Hydromatic Submersible Sewage
Grinder Pumps (model SPGL200M2-2) with a 46 gpm maximum capacity each.
4.1.1 Soil Application Rates
Based on the United States Department of Agriculture Natural Resources Conservation Service soils
map, the soil in the Airport development area is typically Linne Clay Loam (LbD), San Ysidro Loam (Sc),
and Solano Loam (Sk). The permeability of these soil types range from 0.2-0.6, 0.6-2.0, and 0.6-2.0
inches per hour, respectively. The geotechnical investigations conducted as part of the Byron Airport
Engineer’s Design Report showed near surface soil conditions of silty clay and sandy clay along Runway
12-30 which would correlate with an infiltration rate of 0.6. For this analysis, a conservative infiltration
rate of 0.6 inches per hour was assumed, which equates to a percolation rate of 100 minutes per inch and
a soil loading rate of 0.2 gallons per square feet per day1.
4.2 Existing Septic System Capacity and Current Demand
The existing septic system capacity is limited to the capacity of the leach field. As shown in the as-built
plans, the septic system leach field is approximately 8,600 square feet. With a soil loading rate of 0.2, the
leach field has a capacity of 1,720 gallons per day (gpd).
The current septic system demand is low due to the few water users. The main water uses at the Airport
include 7 sinks, 5 toilets, 3 urinals, and the aircraft wash rack. There are no restrooms located inside the
Byron Jet Center; however, there are stubbed utilities for future connection to water and sewer service.
1 Percolation Rates and Soil Loading Rates are from Appendix 2 of the Contra Costa Health Services Health Officer
Regulations Chapter 420-6.
11
X:\4186500\121867.00\CORR\Rpts\Byron Airport Infrastructure Study Report.doc
In order to estimate the peak sewage flow, the number of aircraft based at the Airport (112 aircraft) was
multiplied by the estimated sewage flow for a service station (10 gpd2) and then multiplied by a factor of
60% since all aircraft are not expected to be maintained during a peak day. Therefore, the estimated
peak daily sewage flow for the existing conditions is 672 gallons, or approximately 39% of the capacity.
The existing system does have capacity to support future development and can handle an additional
1,048 gpd. The extent of development that the system can handle would depend on the type of
development. For example, restroom facilities require approximately 5 gallons per person per day, so the
existing system has sufficient capacity to support approximately 210 additional users per day.
4.3 Sanitary Sewer System for Future Development
The septic system analysis was based upon design flow criteria stated in the Central Contra Costa
Sanitary District’s Collection System Master Plan Update. For this analysis, the septic system
conservatively assumed the entire developable area would be converted to Industrial uses. The base
wastewater flow (BWF) used in the analysis was 1,000 gallons per day (gpd) per acre. The table below
summarizes the short and long term anticipated wastewater generation rates.
Land Use Category
Area
(acres)
Wastewater Flows
(gpd)
Short-term development 57.6 57,600
Long-term development 96.7 96,700
Total 154.3 154,300
4.3.1 On-Site Expanded Sewage Leach Fields
The near-term development is estimated to require a minimum 44,400 gallon septic tank and 6.6 acres of
leach field. The long-term development is estimated to require an additional minimum 73,700 gallon
septic tank and 11.1 acres of leach field. Large leach fields of these sizes are typically not used due to
the high initial construction and operations and maintenance cost, so several smaller leach fields would
be required to support the development.
The on-site handling of the potential near-term and long-term development is not feasible at a centralized
location given limitations on leach field sizing. However, septic systems with leach fields would be
feasible as separate systems at each development site. Requiring each development to construct
individual septic systems would eliminate the need for sanitary sewer piping within the Airport, but would
reduce developable acreage, increase permitting requirements, and increase construction and operations
and maintenance (O&M) costs for the developments.

Regulations Chapter 420-6.

X:\4186500\121867.00\CORR\Rpts\Byron Airport Infrastructure Study Report.doc
4.3.2 On-Site Sewage Treatment
On-site treatment is feasible with a package wastewater treatment plant. There are a number of
manufacturers of packaged wastewater treatment plants that would meet the Airport’s treatment needs
for both short term and long term development. The treatment plant would be permitted through the
Regional Water Quality Control Board (RWQCB) General Order 97-10. The treatment plants are
available in both above ground and partially underground models and with a wide range of flow rates. A
package wastewater treatment plant would include the following components and processes:
• Influent equalization chamber
• Sludge holding chamber/aerobic digester
• Aeration chamber
• Clarifier
• Filter Equipment (for irrigation discharges)
• UV Disinfection
One issue with on-site treatment is the disposal of the treated effluent. The effluent can be treated to
meet California Title 22 requirements which would allow for the treated effluent to be used for landscape
irrigation.
Permitting a new treatment plant is a lengthy process as the RWQCB prefers regionalization of sewage
treatment. One factor that will work in favor of permitting the use of a package treatment plant is that the
Airport is not in proximity to a regional wastewater treatment facility that has sufficient capacity; therefore
the RWQCB would be more likely to approve a new treatment plant.
A package sewage treatment plant does require ongoing O&M costs, primarily for labor and electricity
usage. The Airport could perform O&M wastewater treatment activities with the proper certifications or
could contract for the O&M services. The RWQCB requires regular reporting of the plant operation. For
planning purposes, we estimate that the plant would require the following O&M expenses:
1. Electricity - 25 HP x 0.735 KW/HP x 24 hrs/day x 365 days/year x $0.12/KWH = $19,300/year
2. Labor (operation requires 1 man hr/day) - $40/hour x 365 hours/year = $14,600/year
3. Replacement (typically 2% of equipment cost annually) - $375,000 x 2% = $7,500/year
4. Chemicals - $0 for UV disinfection
Total O&M cost is estimated at $41,400 per year
4.3.3 Discovery Bay Sewer System Connection
The Town of Discovery Bay CSD was formed in July 1998 with the responsibility to provide water and
wastewater services to the Discovery Bay community. The CSD recently completed their sanitary sewer
Master Plan in February 2012 and providing sewage service to the Airport was not anticipated in the Plan.
In discussions with the CSD, sufficient capacity is available and the CSD would be open to discussions
on serving the Airport. Since the Airport and sewage forcemain route are outside of Discovery Bay’s
service boundaries, the connection would have to be approved by the Contra Costa LAFCO. It is not
13
X:\4186500\121867.00\CORR\Rpts\Byron Airport Infrastructure Study Report.doc
known at this time if local residents or property owners along the pipeline route would support or oppose
the project.
The assumption made for cost estimating purposes is that the Airport would be responsible for all costs
associated with the connection to the Discovery Bay System, which is likely to include modifications to the
existing sewage lift station (or a new lift station) and a forcemain to Discovery Bay. There may also be a
connection fee to join the CSD; however, a connection fee cannot be negotiated until a firm plan and
construction timeline is developed. Refer to Appendix E for a map of a proposed alignment for a potential
connection to Discovery Bay, and Appendix F for an on-site Utility Plan with a Discovery Bay connection.
4.3.4 Byron Sewer System Connection
The Byron Sanitary District operates the Waste Water Treatment Facility (WWTF) for the community of
Byron. The WWTF is permitted for a sewage flow of 96,000 gpd and is currently operated at
approximately 56,000 gpd. The District has indicated that the Airport could connect to the WWTF, but a
major expansion would be required to handle the estimated flow from the full development of the Airport.
The WWTF needs to retain sufficient spare capacity to allow for increased flows from the Byron
community and the fully developed sewage flow from the Airport exceeds the remaining WWTF treatment
capacity.
Since the Airport and sanitary sewer forcemain route are outside of Byron’s service boundaries, the
connection would have to be approved by the Contra Costa LAFCO.
4.4 Opinion of Probable Construction Costs (OPCC)
A comparative OPCC was developed for the potential improvements required to support future
development. The OPCC only included the major construction components for each scenario. Unit costs
were estimated using the RS Means Heavy Construction Cost Data Manual 2013, Contractor bids for
related work, and discussions with contractors/suppliers.
4.4.1 On-Site Expanded Sewage Leach Fields
An OPCC was prepared for providing sewer service to the near-term and long-term potential
development areas. Since the existing sewer lift station and leach field cannot support the full future
development, the OPCC includes a sewer pipeline and a sewer lift station. A separate sewer system
would be required for the near-term and long-term development areas due to the size of the leach field.
The OPCC’s for the near-term and long-term development are provided below. The long-term
improvements assume that the near-term improvements have already been constructed.

An OPCC was prepared for providing sewer service for the near-term and long-term potential
development areas. Since the existing sewer lift station cannot support the full future development, the
OPCC includes a sewer pipeline and a sewer lift station. The costs include a budgetary estimate of the
package wastewater treatment plant required for both the short-term and long-term development.
However, it is recommended that the Airport install the package wastewater treatment plant for the full
build-out (near-term plus long-term development) initially due to permitting and site constraints.
Constructing a near-term only package treatment plant would only be recommended if the long-term
development were determined to be indefinitely delayed (beyond the long-term time frame) behind the
near-term development. The OPCC’s for the near-term and long-term development are provided below.
The long-term improvements assume that the near-term improvements have already been constructed.

plant required is constructed as part of the near-term development. The long-term costs would include
pipe extensions to connect to the long-term development areas.

An OPCC was prepared for delivering sewage flow to Discovery Bay for the existing developed areas and
the near-term and long-term potential development areas. The alternative includes modifications to the

5. Domestic Water System
The domestic water system analysis was based upon design flow criteria stated in the Central Contra
Costa Sanitary District’s Collection System Master Plan Update. Typically, sanitary sewer design flow is
approximately 70% of the domestic water design flow. However, since the domestic water design flow
usually includes irrigation, minor losses, and fire protection (fire protection is a separate service for the
Airport), it was concluded that a 1:1 ratio between domestic water and sanitary sewer design flows would
be appropriate.
For this analysis, the domestic water system conservatively assumed the entire developable area would
be converted to Industrial uses. The design flow used in the analysis was 1,000 gpd per acre.
5.1 Existing Domestic Water System
The existing domestic water system consists of a groundwater well with a 4,000 gallon holding tank. The
domestic water system includes a booster pump and chlorination system. The domestic water system is
non-potable and is not used for fire protection.
The groundwater well was drilled and installed by Dejesus Pump and Well Drilling, Inc. (Dejesus Pump) in
September 1994. The well is 200 feet deep and consists of a 6-inch diameter plastic casing placed inside
a 12.25-inch diameter bore hole. The well casing is screened from 50-70 feet and 180-200 feet below
ground surface, with the remaining casing blank. The annular space in the upper 50 feet was filled with
17
X:\4186500\121867.00\CORR\Rpts\Byron Airport Infrastructure Study Report.doc
cement and the remaining 150 feet was filled with 0.25 inch gravel. The Well Completion Report is
included in Appendix G.
The domestic water system includes a 2-inch diameter pipeline extending from the well to the northwest,
parallel to the taxiway and past the hangars to the Byron Jet Center. The existing water system pipeline
is shown on the Utilities Plan in Appendix D.
5.2 Existing Domestic Water System Capacity
The groundwater well production has significantly decreased since it was developed, and the County
estimates it pumps approximately 40-60 gallons per hour. There have been instances where a faucet
was accidentally left on or a toilet continued to run causing the tank to drawdown and the well pump to
run continuously. The Airport has had to fill the tank by hauling water from off-site sources. In addition,
the Airport has experienced times when the groundwater well was not producing any water because the
aquifer was dry due to a drought.
The existing domestic water system capacity was based on the California Department of Public Health
regulations, specifically Section §64554 of the California Waterworks Standards (CWS) Title 22, Chapter
16, California Code of Regulations, CCR. The CWS states that the system shall meet at least 4 hours of
peak hourly demand (PHD) through source supply, storage, and emergency source connections. The
PHD of the existing system is conservatively 520 gallons per hour, based upon the area of the existing
facilities. At current water demands, the tank will deliver 2,080 gallons during four hours of PHD. The
supply to the tank, based on the well pump estimates, will fill 160 gallons in 4 hours. Thus, the current
operational storage volume is 1,920 gallons (2,080 gallons minus 160 gallons). Since the existing
domestic water system utilizes a 4,000 gallon tank, the current water system is at approximately 48%
capacity.
The existing domestic water tank has capacity to support future development and can provide an
additional 2,080 gallons of water over a 4-hour period of peak hourly demand, or approximately 560
gallons per hour, provided that there is an adequate supply from the well. The extent of development the
system can handle would depend on the type of development at the Airport.
5.3 Domestic Water System for Potential Development
The development of the Airport would require a significant amount of domestic water, which would need
to be potable to support the various users. Based on the areas reserved for potential development, the
water design flow would be 57,600 gpd and 96,700 gpd for near-term and long-term development,
respectively, based on an industrial demand of 1,000 gpd of developable area. The full build-out demand
of water for domestic uses is projected to be 154,300 gpd.
5.3.1 On-Site Water System
Based on a review of nearby groundwater wells and conversations with Dejesus Pump, there is a low
probability of locating a groundwater source in the area with the supply and water quality needed to
18
X:\4186500\121867.00\CORR\Rpts\Byron Airport Infrastructure Study Report.doc
support the future development. The stratigraphy in the area changes quickly over a short area, so the
presence of a quality aquifer similar to the supply for the nearby Discovery Bay wells is not likely. Water
quality tests taken at the location of the existing well prior to development indicated that the water
contains about 13,000 mg/l of total dissolved solids, and water of this high concentration is considered not
drinkable. A potential location for a water source could be near the Byron Hot Springs, but there is also a
high possibility for salt in this source. Another location for a new well may be the area north of Runway
12-30 towards Armstrong Road instead of the current location to the west of the intersection of the two
runways.
To determine the availability of groundwater to supply the development at the Airport, a few test wells
should be drilled as part of the decision process on how to move forward on water supply. Test well
locations need to be based on a review of nearby groundwater wells. The test wells would be pumped to
establish the reliable quantity of water available and also tested for water quality to establish the
treatment requirements needed to treat the water for potable uses.
The groundwater aquifers in the area are expected to be low yielding (approximately 10 gpm), so more
than one groundwater well would likely be required to provide adequate water for the future development.
The build-out demand for domestic water is approximately 110 gpm. However, for cost estimating
purposes, groundwater conditions supporting a yield of approximately 40 gpm was assumed and four
wells were included in the OPCC (two well for near-term and two well for long-term development). It
should be noted that if a high yielding aquifer is not located, constructing a series of multiple low-yielding
wells (5 or more) is not cost effective and another source of water should be considered.
If on-site water sources are identified, an option for water treatment would be to install a Z-Box Packaged
Treatment Plant manufactured by GE. The GE treatment plants are pre-engineered systems that are
cost effective and compact solutions for potable water treatment. The packaged system uses an
ultrafiltration membrane which effectively blocks particles, bacteria, viruses and cysts from water supplies.
The system was designed with an expandable setup, so the system can be installed with a single
membrane tank (up to 100,000 gpd capacity) for the near-term development, and expanded with an
additional membrane tank for the long-term development. The Z-Box S Packaged Plant has a maximum
capacity of 400,000 gpd, so it has the capability to be expanded beyond the expected near-term and
long-term development needs. The Z-Box S Packaged Plant with two membrane tanks (200,000 gpd
capacity) would require a space approximately 16-feet long by 8-feet wide, and approximately 6-feet tall.
The Z-Box S Packaged Plant is included in the OPCC for on-site water improvements below. However, it
should be noted that the Z-Box Packaged Treatment Plant will require continual O&M activities. For
planning purposes, we estimate that the plant would require the following O&M expenses:
1. Electricity - 20 HP x 0.735 KW/HP x 24 hrs/day x 365 days/year x $0.12/KWH = $15,400/year
2. Labor - (operation requires 1 man/hr/day) $40/hour x 365 hours/year = $14,600/year
3. Replacement - (typically 10% of membrane replacement cost) $25,000 x 2% = $2,500/year
4. Chemicals - $0 for UV disinfection
Total O&M cost is estimated at $32,500 per year

5.3.2 Discovery Bay Water System Connection
The Discovery Bay CSD recently completed their water services Master Plan in 2012 and an Airport
connection was not anticipated in the Plans; however, the facilities do have capacity to provide water for
domestic and fire protection uses. It should be noted that the capacity may not be available in the future,
depending on development within the CSD boundaries and timing of Airport development.
For cost estimating purposes, it was assumed that the Airport would be responsible for all costs
associated with the connection to the Discovery Bay System, which is likely to include a water storage
tank, pipelines, and a water booster pump station. Discovery Bay may also charge a connection fee for
connecting to the system. A budgetary cost estimate for the fee is not available and would be negotiated
at the time of application to the CSD. The connection would have to be approved by the Contra Costa
LAFCO, as described above under the fire protection discussion. Refer to Appendix E for a map of a
proposed alignment for a utility connection to Discovery Bay.
5.3.3 Byron Bethany Irrigation District Water Supply
The Byron Bethany Irrigation District (BBID) provides untreated water to the Byron area from March to
October, dependent upon irrigation demands. The BBID has indicated they have the ability to supply
water to the Airport year-round, and is serving the Mountain House development in a similar
arrangement. BBID owns a 20-million-gallon per day (MGD) pumping plant along the California Aqueduct
which pumps water to the Mountain House water treatment plant through a water main. The water
treatment plant is currently operating at 15 MGD, with full build-out of 20 MGD. The pumps within the
pumping plant could be improved by including a variable frequency drive, or potentially installing a new
small pump along with connecting piping and valving to supply the Airport. The BBID pumping plant is
located approximately 2 miles from the Airport. The water would require treatment from a packaged
water treatment plant such as the Z-Box system described above.
Two options are available to convey water from BBID to the Airport: (1) utilize the existing irrigation canal,
or (2) construct a pipeline. The use of BBID irrigation water for potable uses would require a sanitary
survey and would have to be approved by the State Department of Health Services (DHS). Since the
open canal has the potential for contamination from surface runoff, grazing livestock, or vandalism, it can
be foreseen that the DHS would not be favorable to this alternative. Therefore, this alternative will include
a new buried pipeline to deliver water to the Airport. Refer to Appendix H for a map of a proposed
alignment for a water conveyance facility to the Airport from the BBID pumping plant
BBID water would require treatment for potable uses. The Z-Box packaged treatment plant discussed
above would be required to treat the water for potable use. The treatment plant could be operated and
maintained by the Airport, or the BBID could operate the treatment facility. In addition, the water system
would require a booster pump and water storage tank. The water storage tank would be sized at 150,000
gallons, which is approximately the average day demand at full build-out development.
20
X:\4186500\121867.00\CORR\Rpts\Byron Airport Infrastructure Study Report.doc
5.3.4 Combination Domestic Water Supply and Fire Protection
A permanent water supply connection to BBID or Discovery Bay would allow the Airport to utilize the
supply for both domestic uses and fire protection and eliminate the need for the fire pond and fire pump.
Utilizing water from Discovery Bay for fire protection in addition to domestic uses is feasible. The
domestic water and fire protection water could utilize a common pipe, similar to municipal water systems
because the water is treated by Discovery Bay.
A storage tank and booster pump station with back-up redundant pump would need to be sized to provide
the flows and volume of water required for firefighting in addition to the domestic water requirements.
The water storage tank would require a storage volume of 600,000 gallons and the booster pump station
would need a capacity of 3,110 gpm. The water system is required to have sufficient capacity to deliver
the fire flow and the domestic uses simultaneously, 3,000 gpm for fire flow and 110 gpm for domestic
uses. The water storage tank would have several days of water storage under normal usage conditions.
Chlorine may need to be added to the water storage tank to maintain the minimum level required for
disinfection.
Utilizing water from a BBID domestic water pipeline for both domestic water supply and fire protection
would be feasible, but more expensive. The additional supply required for fire protection would require
more extensive pump upgrades in the BBID pump station.
The fire protection system would continue to utilize a separate pipeline to avoid having to treat the water
used for fire protection. A common system for both fire protection and domestic water uses would require
sizing the treatment plant to accommodate the fire flows at 3,000 gpm, which would be a significantly
more expensive plant. A common system would also limit the available water for firefighting to the
treatment plant’s capacity and storage volume. Currently, there is no limit on available water during
irrigation season, and arrangements can be made with BBID for supplying water during the off-season.
Utilizing a new BBID supply for both fire protection and domestic supply would require the following:
• Significant upgrades to the BBID pump station
• Two water storage tanks for fire protection and treated domestic water
• Two booster pump stations for fire protection and domestic water
• Separate pipelines
5.4 Opinion of Probable Construction Costs (OPCC)
A comparative OPCC was developed for the potential improvements required to support future
development. The OPCC only included the major construction components for each scenario. Unit costs
were estimated using the RS Means Heavy Construction Cost Data Manual 2013, Contractor bids for
related work, and discussions with contractors/suppliers.
21
X:\4186500\121867.00\CORR\Rpts\Byron Airport Infrastructure Study Report.doc
5.4.1 On-Site Improvements
An OPCC was prepared for providing domestic water service to the near-term and long-term potential
development areas. Since the existing domestic water well and tank cannot support the near-term or
long-term future development, the OPCC includes the drilling of a new well, a new storage tank, a new
water treatment facility, and water pipeline to the on-site development areas. A separate water system
was included to support the long-term development areas. The OPCC’s for the near-term and long-term
development are provided below. The long-term improvements assume that the near-term improvements
have already been constructed.

The well cost estimate takes into account the probability that test wells and additional measures would
need to be included to site and develop the well to produce and adequate water supply. The cost
estimate includes the following:
• Test wells and test pumping to locate optimum well site
• Well development
• Well casing, piping, pump and motor, and connection to water system
• Electrical supply and controls

5.4.2 Connection to Discover Bay
An OPCC was prepared for providing water for domestic uses from Discovery Bay for the existing
developed areas and the near-term and long-term potential development areas. This scenario assumes
that fire protection would be handled by the on-site system. The alternative included a transmission main
from Discovery Bay and on-site booster pump station, water storage tank, and piping. The OPCC does
not include any connection fees that may be required by Discovery Bay, or any allowances for
environmental mitigation. The OPCC’s for the Discovery Bay connection, booster pump station, and
water storage tank would need to be constructed in the near-term.

5.4.1 Connection to BBID
An OPCC was prepared for providing water for domestic uses from BBID for the existing developed areas
and the near-term and long-term potential development areas. This scenario assumes that fire protection
would be handled by the existing on-site system. The alternative included a transmission main from BBID
and on-site pipe extensions to the potential development areas. The OPCC does not include any
connection fees that may be required by BBID, or any allowances for obtaining utility easements or
environmental mitigation. The pipeline route is located primarily on Airport property or within BBID
property. The pipeline route located on Airport property is largely within the areas designated as the
Biologically Sensitive Area and would need to be permitted. It is anticipated that the water transmission
from BBID, package water treatment plant, storage tank, and booster pump station would be constructed
for the near-term development area. The OPCCs for connection to BBID are provided below. The BBID
23

6. Private Utilities
Telephone and electric service is provided to the Airport. Both of these utilities are routed to the Airport
from the intersection of Holey Road and Byron Hot Springs Road. The utility lines cross beneath the
runway and taxiway to the electrical room located inside the Fixed Base Operator Hangar. No television
or natural gas services are provided to the airport; however, several empty conduits are installed under
the runway and taxiway to allow for future utilities.
6.1 Electrical Service
The electrical service to the Airport is provided by the Pacific Gas and Electric Company (PG&E). The
existing service is delivered by a 12-kilovolt line, which is sufficient to supply power to the future
development at the Airport discussed in this report.
24
X:\4186500\121867.00\CORR\Rpts\Byron Airport Infrastructure Study Report.doc
6.2 Natural Gas Service
There is currently no natural gas service provided to the Airport. However, there is a PG&E high pressure
transmission line that crosses Runway 5-23. PG&E doesn’t foresee any issues with extending natural
gas service to the Airport; however, the final determination cannot be made until a formal service request
has been submitted.
6.3 Communication Service
The communication service to the Airport is currently provided by AT&T through underground lines.
Telecommunications, video/television, and data services can be added to the Airport to serve future
development. There is an existing fiber-optic line along Byron Highway, which can be extended to the
Airport’s demarcation point and then wired throughout the Airport property to the individual users. The
Airport would have to submit a service request to AT&T describing the types of services to be added at
the Airport property.
6.4 State Route 239 TriLink Program
First identified in 1959, SR-239 is a legislatively approved, but unconstructed route in the California state
highway system. SR-239 is a potential multimodal link between SR-4 near Brentwood and I-205 west of
Tracy in San Joaquin County. The route has not been adopted by the California Transportation
Commission; however, Contra Costa County was awarded $14 million for initial study and planning under
SAFETEA-LU in 2005. Administration of the study, now called TriLink, was transferred to the Contra
Costa Transportation Authority in January 2012. The Parsons Transportation Group is working on the
project and is performing a study to identify ways to improve transportation in the area.
The TriLink project study currently includes a connector link to the Byron Airport, which could improve
access to the airport and potential future airport development. In addition, the TriLink project includes
utility planning, which could potentially be extended to serve the airport. However, at this time the TriLink
feasibility analysis is too premature to include in the report. It is recommended that the Airports Division
contact the SR-239 planning group to inquire about potential utility connections when the near-term and
long-term development plans are prepared.
7. Storm Water System
7.1 Existing Infrastructure
The existing storm water system includes a combination of storm drainage pipes and ditches to convey
water to the detention basin. Along Runway 12-30, storm drainage pipes convey water to the northeast
side of the runway to a parallel drainage ditch. The drainage ditch flows southeast to the detention basin.
The storm water from the existing development west of the runway is conveyed through pipes and is
connected to the piping beneath the runway and to the drainage ditch. Along Runway 5-23, storm
drainage pipes convey water to the south side of the runway to a parallel drainage ditch. The drainage
25
X:\4186500\121867.00\CORR\Rpts\Byron Airport Infrastructure Study Report.doc
ditch flows easterly to the detention basin. The storm drainage facilities were designed for a 10-year
storm event.
The existing storm water detention basin east of Runway 5-23 has an area of approximately 15 acres.
The existing basin was designed to reduce the peak storm water flows of the pre-development condition
at the Airport for the 3-, 6-, and 12-hour storm duration for a 10-, 25-, 50-, and 100-year storm event. The
storm water discharges from the property into the roadside ditch along Holey Road. The storm water
flows east along Holey Road to Byron Highway and then north along Byron Highway to a ditch which
flows into the Italian Slough.
7.2 Storm Water Infrastructure for Future Development
The storm water infrastructure improvements required to serve the near-term and long-term future
development were evaluated to meet the requirements of the Contra Costa Clean Water Program
(CCCWP): Stormwater C.3 Guidebook, 6th Edition. The Guidebook requires both flow control and water
quality control to be incorporated into the storm water facilities.
The CCCWP recommends working with the County and utilizing the USEPA Hydrologic Simulation
Program-Fortran (HSPF) model to simulate flows for a 30-year period. Given the preliminary nature of
the planned developments, we utilized an alternative modeling approach (the Rational Method) for both
flow control and water quality control, which meet CCCWP requirements. The Rational Method is more of
a generalized or programmatic approach to detention basin sizing. The C.3 Guidebook stipulates that the
basin should be sized to detain 80% of the total runoff during the simulation period. As the development
plan becomes more focused, the Airport would begin preparing a Storm Water Master Plan and
consulting with the CCCWP on modeling the proposed developments with the HSPF model.
In sizing the detention basin, it was assumed that all storm water would be treated at the detention basin.
Low Impact Design (LID) features on the individual development areas were not included. As part of the
future development, various on-site LID features may be required on individual sites, which would reduce
the required size of the detention basin. The lands north and east of the existing basin could be utilized
to expand the basin to support the future development. The existing basin could also be modified to meet
the storm water requirements for the existing airport and future development, but for the purposes of this
evaluation, new detention capacity constructed adjacent to the existing basin was considered in order to
be conservative in cost estimating.
The storm water conveyance system for future development was preliminarily designed using concrete
pipes to convey the storm water to the detention basin. The storm pipe sizing is based on a 10-year
storm. It may be feasible to utilize the existing ditches parallel to the two runways to convey storm water
from the development areas. The capacity of the ditches would need to be evaluated to determine if they
could support the additional flows. For the purposes of this evaluation and to be conservative in cost
estimating, storm drainage pipes were considered.
26
X:\4186500\121867.00\CORR\Rpts\Byron Airport Infrastructure Study Report.doc
7.2.1 Near-Term Storm Water Improvements
The near-term storm water improvements include an expansion of the detention basin, water conveyance
pipes, and storm drainage inlets. The detention basin volume required for the near-term development is
approximately 1.9 acre-feet. For estimating purposes, detention basin dimensions of 380 feet long,
110 feet wide, and 2 feet deep were assumed. A concrete broad crested overflow weir for outlet control
was also included to prevent overtopping of the basin during extreme storm events. The storm water
conveyance for the development area southwest of Runway 12-30 includes approximately 5,600 LF of
18-inch and 24-inch diameter pipe and 14 drainage inlets/manholes. The storm water conveyance for the
development north of Runway 5-23 includes approximately 2,600 LF of 12-inch diameter pipe and 7
drainage inlets/manholes.
7.2.2 Long-Term Storm Water Improvements
The long-term storm water improvements include expansion of the detention basin in addition to the
expansion required for the near-term development. Conveyance pipes and storm drainage inlets would
be extended to serve the development areas. The detention basin volume required for the long-term
development is approximately 2.3 acre-feet. For estimating purposes, detention basin dimensions of
420 feet long, 130 feet wide, and 2 feet deep were assumed. A concrete broad crested overflow weir for
outlet control was also included to prevent overtopping of the basin during extreme storm events. The
storm water conveyance for the development area northeast of Runway 12-30 includes approximately
5,400 LF of 18-inch diameter pipe and 13 drainage inlets/manholes.
7.3 Opinion of Probable Construction Costs (OPCC)
An OPCC was developed for the storm water system improvements required to support future
development. The OPCC only included the major construction components. Unit costs were estimated
using the RS Means Heavy Construction Cost Data Manual 2013, Contractor bids for related work, and
discussions with contractors/suppliers.
7.3.1 On-Site Improvements
An OPCC was prepared for extending the existing storm water system to the near-term and long-term
potential development areas. The OPCC’s for the near-term and long-term development are provided
below.
The near-term developments include extensions of the storm water system to serve the development
areas along the west side of Runway 12-30.

8. Recommendations
8.1 Existing Infrastructure
No upgrades are recommended for the fire protection system for the existing conditions at the Airport.
The existing fire protection system is adequate for the current usage at the Airport. The fire protection
system meets current code requirements and has adequate firefighting capacity when the pond is full and
during the operating season of the Byron-Bethany Canal. The nearly one million gallons of stored water
in the 96-inch diameter pipeline and the supplemental pump provide sufficient backup supply outside of
irrigation season. The on-going O&M activities should continue in order to maximize the life of the
system. However, since the Airport has historically had issues with the fire pump, it may be beneficial to
investigate the implementation of an on-site back-up system in case the main fire pump were to fail.
No septic system upgrades are recommended for the existing conditions at the Airport. The existing
sanitary sewage system is currently functioning adequately and has approximately 1,000 gpd of
remaining capacity. Leach fields typically have a limited useful life, approximately 15-20 years depending
28
X:\4186500\121867.00\CORR\Rpts\Byron Airport Infrastructure Study Report.doc
on usage. At some point, the leach field will need to be replaced, even without additional development.
There is a reserve area established adjacent to the existing leach field. Since the existing system is near
the typical useful life cycle for septic systems, the system should continue to be monitored and inspected
to identify potential problems.
Since the existing groundwater well is not functioning adequately, we recommend that the Airport conduct
test wells to identify a better location for a new groundwater well as described in Section 5. The
groundwater well has been losing productivity and does not provide sufficient flow for current uses. The
quality of the groundwater is also poor and the water is considered non-potable due to high levels of total
dissolved solids. Rehabilitating the well may increase the production, but based on discussions with
Dejesus Pump, it appears that the well is not located in a productive aquifer.

8.3 Fire Protection for Future Development
The fire protection system was modeled to extend water pipelines to the near-term and long-term
development areas. With the water pipeline extended to the full build-out condition (near-term and long-
term development), the fire protection system meets the current code requirements and has adequate
firefighting capacity when the pond is full and during the operating season of the Byron-Bethany Canal.
Similar to the existing conditions, the approximately one million gallons of stored water in the 96-inch
diameter pipeline and the supplemental pump will continue to provide sufficient backup supply outside of
the irrigation season. In addition, water supply to the fire pond should not be an issue since the BBID has
stated they would support the Airport with fire suppression by delivering water outside of the normal
irrigation season, as needed.
At this moment, our recommendation is to continue to utilize the existing fire protection system with
extended distribution piping and fire hydrants for the near-term and long-term development areas. The
on-going O&M activities should continue in order to maximize the life of the fire pump system. An
investigation of the fire pond’s filtering system could reduce the amount of debris from entering the
system and thereby extending the life of the fire pump.
8.4 Sanitary Sewer for Future Development
The existing sanitary sewage septic system is currently functioning adequately and has limited capacity to
support future development. However, due to the required size and cost of septic systems to support the
future development, the use of septic systems for Airport expansion is not recommended. The size of the
leach field as well as the leach field reserve area would also add constraints on Airport development.

At this moment, it is our recommendation that the Airport explore the construction of an on-site
wastewater treatment plant to handle sanitary sewer flows generated from Airport development. With this
alternative, the Airport would have control of the treatment system, and could possibly use treated effluent
for landscape irrigation. This alternative would require on-going O&M of the treatment plant; however,
this work can be contracted to an outside service. In order to reduce construction costs, it is
recommended that the package wastewater treatment plant be installed for the required full build-out
capacity during the near-term development plan, unless it is expected that the long-term development
would be delayed indefinitely (beyond the long-term time frame).
8.5 Domestic Water for Future Development
The development of the Airport would require a significant amount of domestic water, which would need
to be potable to support the various users. Based on a review of nearby groundwater wells and
conversations with Dejesus Pump, there is a low probability of locating a groundwater source in the area
with the supply and water quality needed to support the future development. The existing groundwater
well production has significantly decreased since it was developed. Therefore, we do not recommend the
use of groundwater wells to support future site development.
At this moment, it is our recommendation that the Airport explore construction of a package water
treatment plant to treat water from BBID for potable water uses. The use of BBID water is a reliable
source, and BBID has been open to discussions to supply water to the Airport. This alternative would
require on-going O&M of the packaged treatment plant; however, this work can be contracted to the BBID
or an outside service. A similar system is used for the nearby Mountain House community, which
receives water from BBID and treats the water for potable uses at the treatment facility.
