Revenue Neutral Changes

1. Fire (General Fund) – NACFR Service Level Adjustment: $93,364; 4.0 FTE (base)

Fire requests approval for a $93,364 revenue neutral appropriation increase, along with a 4.0

FTE increase, to accommodate an addendum to the current service level agreement (SLA) with

North Ada County Fire & Rescue (NACFR).

NACFR has indicated that its district revenues are increasing and has requested that NACFR

Station 16 be staffed as a four person engine company. Station 16 is currently staffed as a three

person engine; this staffing increase would provide for a greater level of safety as it is the only

station operating in the district; however, it is continued to be expected that response times may

be longer in some areas.

The 4.0 FTE increase is a base request. The requested budget appropriation is for the remainder

of FY 2015; funding for FY 2016 would be adjusted accordingly.

Parks & Recreation (Parks) requests approval to expedite the Boise Hills Greenup project along

with an expenditure appropriation of $12,000 into the current fiscal year. The Boise Hills

Greenup capital project was originally built as part of the FY 2016 budget and was 100% Impact

Fee funded for $755,000. This request would allow Parks to get a pump and well study

completed before October 1st which would allow the Department to move dirt this fall. This

request would allow the project to begin immediately.

Public Works requests approval to transfer $12,600 in available budget from the Geothermal

Miscellaneous Improvements capital project to the JUMP Geothermal Extension capital project.

The geothermal pipeline extension to the JUMP and Simplot Office Building is being

constructed to provide geothermal water as a primary heating source. Preliminary construction

estimates anticipated project costs to be $440,000. A service agreement was prepared stating

that the developer would fund the anticipated construction costs in exchange for an equal credit

of geothermal service. Final construction costs are now estimated at $452,600. The

JUMP/Simplot Buildings service agreement will remain unchanged. The additional cost will be

covered by the Geothermal Fund.

Public Works requests approval to transfer $125,000 in available budget from the Sewer

Extension capital project to the Sewer Rehab capital project for additional sanitary sewer line

repairs.

The recent Bench and Northwest sewer district mergers added approximately 200 miles of sewer

pipeline to Boise City sanitary sewer collection system. The expansion of the sewer system has

resulted in an increase of sewer repairs in which the existing sewer rehab capital budget did not

take into account. This request will allow sufficient funding for these repairs.

Public Works requests approval to transfer $789,000 in available budget from the Temperature

Mitigation capital project to the Facility Planning capital project to further evaluate EPA

obligations.

In 2012 EPA permit requirements outlined significant temperature reduction obligations that the

City must meet within a 10 year time frame. Budget for temperature mitigation studies were

approved in FY 2014 as a separate capital project to evaluate options that could be used to

comply with upcoming requirements. After further evaluation, staff recommends that funds be

combined into the Facility Planning capital project as part of a system wide temperature

mitigation planning effort. Staff is working with the EPA and Idaho DEQ to determine the types

of permits required and the conditions of those permits if reuse or groundwater discharge options

are pursued.

South Farm (TMSF) capital equipment fund into the TMSF Farm Equipment Maintenance

Building capital project.

The TMSF Office and Maintenance Building master plan identified significant equipment needs

for the design and construction of the new facility. Requested funds will be used to purchase

equipment items that need to be incorporated into the overall project based on critical timing,

logistics, installation requirements and warrantee duration. This transfer is only necessary

because the major equipment is part of the total capital project rather than purchased separately.

Public Works is requesting approval of an $8,500,000 appropriation increase to the Dixie Drain

capital improvement project funded by retained earnings. The requested appropriation is to

expedite spending authority that was originally budgeted in FY 2016 during budget

development.

The current total project budget approved through FY 2015 is $9,723,000. After completion of

the initial design phase in July 2014, a review of estimated project costs indicated a budget

increase would be needed, however a decision was made to delay an additional budget request

until the design was completed and bids were received. A total budget increase of $12.2 million

is based on subcontract bids for the second phase of construction and is consistent with the

previous estimate reported to City Council in March 2015. An increase of $8.5 million is being

requested now and the remaining $3.7 million of the overall increase will be included in the FY

2016 budget. This will bring the total project budget to $21,923,000.The operating costs have

been incorporated into the Sewer Fund annual budget.


Proposed Budget


Use Sewer PW CIP – Dixie Drain $9,723,000 $18,223,000 $8,500,000

11. Public Works (Solid Waste Fund) – Esther Simplot Park Remediation: $4,000,000 (one-

time)

Public Works requests a budget increase of $4,000,000 in the Solid Waste Fund to allow for

expenses related to the Esther Simplot Park (ESP) remediation in accordance with the ESP

Addendum 2 approved by Council on June 23, 2015 via resolution RES-296-15.

Several weeks ago contamination was found during the excavation of the Esther Simplot Park

site. The DEQ is requiring special handling and testing to determine how to dispose of the

materials. $1.5 million of the budgeted cost will be funded by Solid Waste Fund retained

earnings. The other $2.5 million will be funded by an advance from the General Fund. The

Solid Waste Fund will repay the advance in $500,000 increments over five years starting in FY

2016. A 2% Solid Waste customer rate effective October 1, 2015 will rebuild the fund balance

and fund the repayment to the General Fund. The rate increase may be sun-setted once the fund

has regained enough fund balance to complete the repayment.

Boise Airport Part 150 Study Update

Open House #1, June 3rd, 2015

1

Thank you for attending the Open House for the Boise Airport Part 150 Study Update. The purpose of a Federal Aviation Administration (FAA) 14 CFR Part 150 Study is to define the noise exposure levels in and around the Airport and provide noise compatibility planning to help alleviate noise impacts to the surrounding areas and communities. The purpose of this workshop is to review the Part 150 process, present the existing (2015) and future (2020) draft noise contours depicting noise exposure from existing and forecast aircraft operations at BOI, and to review the Airport’s previous Noise Compatibility Program (NCP). You are invited to visit the presentation board area and discuss your questions or comments with the Project Team. The same presentation will be held at 4:30 and 5:30 p.m. Information is provided on:

Commonly asked questions about the Part 150 Study;

Existing and forecast noise model input data;

Existing (2015) and Future (2020) Draft Noise Exposure Contours; and

Approved 2006 Noise Compatibility Program Measures.

Thank you for participating in the Boise Airport Part 150 Study Update. We would appreciate receiving a written record of your comments and questions. Please fill in the Comment Sheet at the back of this package and return it to the sign-in table or mail/email it to the contact listed on the Comment Sheet.

Commonly Asked Questions about the Part 150 Update Study What is a 14 CFR Part 150 study? Title 14 CFR Part 150 (Part 150) was created in 1984 in accordance with the Aviation Safety and Noise Abatement Act of 1979. Its objectives include the following:

Establishing a nationally uniform system of describing aircraft noise and noise exposure in an attempt to eliminate confusion resulting from the use of different descriptors in different communities;

Describing land use compatibility criteria for the guidance of local communities, while recognizing that these criteria will be influenced by local values and factors; and

Providing technical assistance to airport operators and other governmental agencies in preparing and executing noise compatibility planning and implementation programs.

Part 150 describes the specific document that must be submitted to the FAA for acceptance of the Airport’s program. The document must include both Noise Exposure Maps (NEM) and a Noise Compatibility Program (NCP). NEMs are prepared for the existing condition (2015) and future conditions (2020) with existing noise abatement procedures included. The NCP includes a wide range of potential noise compatibility actions including:

Noise Abatement Measures, which consider actions that could reduce aircraft noise levels by changing aircraft procedures and routes of flight.

Land Use Measures, which consider actions that could reduce existing and future non-compatible land uses.

The NCP is essentially a list of the actions the airport operator, in consultation with aeronautical users, local governments, and the FAA, proposes to undertake to minimize existing and future noise/land use non-compatibility. The NCP documentation must recount the development of the program, including a description of all measures considered, the reasons that individual measures were accepted or rejected, how measures will be implemented and funded, and the predicted effectiveness of individual measures and the overall program. What is the Day-Night Average Sound Level (DNL)? DNL is the average noise exposure level over a 24-hour period, with a 10 dB penalty added for aircraft noise occurring during nighttime (defined as 10:00 p.m. through 7:00 a.m.). This weighting reflects the added intrusiveness of nighttime noise events due to the fact that community background noise levels typically decrease by 10 decibels at night. DNL does not represent the noise level heard at any particular time, but rather represents the total noise exposure for the average annual day. DNL is the metric required by the FAA in noise contour development for the assessment of annual average day noise exposure. What is used to model aircraft noise exposure? The FAA requires the use of the Integrated Noise Model (INM) or equivalent model for use in a Part 150 study. This study uses INM to model civilian aircraft noise and the Department of Defense model (NOISEMAP) to model military operations. Each model generates noise exposure levels (e.g., DNL contours) based on input data developed specifically for the airport under consideration. Computer-based noise modeling allows for the projection of future, forecast noise exposure, and importantly, allows for the comparison of potential future scenarios that cannot be captured using noise monitoring. What is an “annual average day?” Part 150 requires the use of an annual average day to assess noise exposure. Annual average daily operations are representative of all aircraft operations that occur over the course of a year. The total annual operations are divided by 365 days to determine the annual average daily operations. Since airports and air traffic are complex systems that vary from day to day due to weather, airline schedules, and other factors, the use of average annual daily operations allows these dynamics to be included in the evaluation of aircraft noise exposure. FAA radar data (which provides information on actual flight operations at Boise Airport including date, time, aircraft type, runway use, flight track, etc.) was used in this study.

How are existing land uses identified? Determination of land use must be based on professional planning criteria and procedures utilizing as appropriate, comprehensive land use planning, zoning, building design, and/or site planning. Both the City of Boise and Ada County provided data on land use, zoning, and development information around Boise Airport. What does the Draft 2015 Noise Exposure Map (NEM) represent? The Draft 2015 NEM represents the existing noise exposure environment at Boise Airport given existing aircraft activity levels and the operational procedures in use today. For the 2015 NEM, over 128,000 annual aircraft operations are represented. What is forecast to occur in 2020? The Part 150 Update study included a detailed forecast of operations for the year 2020. The forecast anticipates that BOI will host over 138,000 operations in 2020. In consideration of the uncertain future of the Idaho Air National Guard’s current A-10 aircraft mission, the Airport has prepared multiple future forecasts that consider different potential Idaho Air National Guard missions, including a continuation of the existing A-10 mission, a replacement F-15 mission, and a replacement F-35 mission. What does the Draft 2020 Noise Exposure Map (NEM) represent? At this time, the Future (2020) Draft NEM represents an increase in passenger jet operations, which follows recent trends at BOI, and presumes that the most likely future scenario for the Idaho Air National Guard is a replacement of the current A-10 mission with F-15 operations, which have notably different noise characteristics from the relatively quiet A-10 aircraft. How can I participate in the Part 150 Update Study? Provide your comments on the study by talking to project team members at this open house and then completing a Comment Sheet. The Comment Sheet may be handed in at the open house or submitted via mail or email. To be considered in the study, comments need to be received or postmarked by July 8th, 2015. In addition, the Draft Part 150 Update Study document will be available for public review and comment in late June, and an additional public open house scheduled for early July. Should you provide your email address tonight, you will be directly informed of the second open house.

What Information is included in the Noise Model? The noise models used in this study require detailed data to produce realistic results. Essentially, the data gathered is used to define and predict, on average, typical aircraft operations at the Airport. Considerations include: Airport Location and Layout Runway location, orientation, elevation, and gradient. Terrain data at 10-foot intervals. Weather, including average temperature, humidity and wind direction: Hot temperatures reduce aircraft performance, while cold temperatures increase

performance. The annual average temperature at the airport is used to compute typical aircraft performance.

The average relative humidity affects how noise is propagated and absorbed by air. Wind data is used in the evaluation of runway use.

Aircraft Flight Operations and Fleet Mix The annual average daily flight operations forecast for the airport for 2015 and 2020 is input

into the model by aircraft type, number of operations, arrival/departure/touch-and-go, and time of day (daytime or nighttime).

In 2015, the Airport hosted over 128,000 annual aircraft operations, including operations by air carriers, the Idaho Air National Guard, charter operators, general aviation activity, and itinerant (non-local) military aircraft. By 2020, the Airport is forecast to host over 138,000 annual aircraft operations. This study has prepared multiple potential future scenarios for the potential type of aircraft flown by the Idaho Air National Guard, including a continuation of the existing A-10 mission, a replacement mission of F-15 aircraft, and a replacement mission of F-35 aircraft. The Airport anticipates that the F-15 mission is the most likely scenario at this time. Noise Model Aircraft Database and Flight Profiles The noise model contains reference noise and performance data for specific aircraft types.

Aircraft manufacturers such as Boeing and Airbus provide the data to the FAA, which is used to calculate an aircraft’s departure and arrival flight profiles, and resultant noise exposure.

Flight profiles model the vertical paths of aircraft during departure and arrival to determine the altitude, speed, and engine thrust of an aircraft at any point along a flight track. Typical aircraft operating weights for a given stage length (e.g., trip length) are factored into profile performance.

Operational Categories Aircraft types are grouped into operational categories by operator (airline, regional, cargo,

military, general aviation, etc.) in order to incorporate unique operational trends into the noise model inputs. For example, the typical runway and flight track use of a jet air carrier aircraft will differ from those of propeller-driven regional aircraft.

Runway Use and Flight Tracks Runway use is the proportion of aircraft that use a runway for departure, arrival, or touch-

and-goes, expressed as a percentage. Runway use is an average daily value based on typical operations over the course of the entire year.

Modeled flight tracks depict the approximate paths, or ground tracks, that aircraft use as they travel to and from the airport. Flight tracks are intended to be representative of typical aircraft operations at the airport.

Runway and flight track use is differentiated by arrival/departure/tough-and-go, operational category and time of day.

Average daily runway use, and flight track location and use, is derived from a sample of actual radar data obtained for periods of time in 2014. Information gathered from discussions with the Idaho Air National Guard and the Airport Traffic Control Tower (ATCT) also informed runway use.

Noise Exposure Contours

Existing (2015) Conditions Figure 1 presents the 2015 Draft NEM. The 2015 Draft NEM was developed using the input data described above for both civilian and military operations. The 2015 Draft NEM considers average runway use and the average location and use of flight tracks. The DNL 65 dB noise contour (the outermost contour shown on Figure 1) also represents the distinction between land uses that are generally considered compatible with aircraft operations and those that are not. Noise-sensitive land uses, such as residential land, schools, places of worship and nursing homes are identified on the map. As shown on the figure, the DNL 65 dB noise contour extends beyond the Airport’s property line into the surrounding land uses in two areas – to the west of the Airport along the extended centerline of the runways, and to the north of Interstate 84. Approximately 87 residential parcels are within or immediately adjacent to the DNL 65 dB noise contour. Future (2020) Conditions Figures 2 through 4 present the 2020 forecast operations at BOI, with different potential missions of the Idaho Air National Guard.

Figure 2 presents the future forecast with a continuation of the A-10 mission. Under this scenario, the changes to the noise contour are minimal, as the Airport would generally operate as it does today, with an increase in the total number of operations occurring only with civilian operations. Figure 3 presents the resulting noise contour with the change in mission of the Idaho ANG from A-10 aircraft to F-15 aircraft. Although it is not certain exactly how an F-15 mission would operate at BOI, this study considered similar F-15 missions (including how frequently the aircraft would fly, what types of training activity would occur, and how noise could be minimized) at other facilities and coordination with the Idaho ANG. Figure 3 is also presented as the Future 2020 NEM as it represents a worst-case scenario for which the City of Boise and Ada County can use to make informed land use and zoning decisions. Under this scenario, the DNL 65 dB noise exposure contour increases in size and includes a larger number of residential parcels (approximately 386 residential parcels within the DNL 65 dB noise contour) and one potentially noise-sensitive facility. The change in noise exposure is due primarily to the different noise characteristics of the F-15 aircraft. Figure 4 presents another alternative scenario for a future mission without the A-10 aircraft. Although it is not anticipated that the new F-35 would be in place by 2020, this aircraft is anticipated to have an active role in the US Air Force fleet in coming years, and as such, the potential noise impact was modeled as part of this study. Under this scenario, approximately 270 residential parcels and one potentially noise-sensitive facility would fall within the DNL 65 dB noise exposure contour.

Approved 2006 Noise Compatibility Program Once the existing and future NEMs have been identified, the Part 150 Update study process begins to evaluate ways to minimize and mitigate noise within and adjacent to the DNL 65 dB noise exposure contour. The NCP can also address preventive land use measures meant to reduce the potential for future development that may be incompatible with aircraft noise. The Airport’s 2006 NCP is reproduced below and the next step in the study is to reevaluate these measures to determine their current applicability. Noise Abatement measures address where and how aircraft operate at BOI, and require consultation and agreement with aircraft operators and the FAA:

Noise Abatement Measures 1 Preferential Runway Use

BOI would request amendment of ATCT standard operating procedures to include alternative flight procedures. FAA reviews, approves, and implements.

2 Departure Turn Altitudes This measure would continue directing jet departures from Runways 28L and 28R to maintain runway heading until reaching 5,000 feet MSL before turning north or south.

3 Departure Turn Altitudes This measure would continue directing non-jet aircraft over 12,500 pounds with destination headings to the north to fly runway heading to 4,500 feet MSL before turning.

4 Departure Turn Altitudes This measure would continue directing VFR departures with destination headings to the north to fly runway heading to the end of the runway before turning.

5 Departure Turn Altitudes This measure would continue to direct north and northwest bound turbojet departures from Runways 10L and 10R to fly runway heading to 5,000 feet MSL before turning north.

8 Distant Noise Abatement Departure Profile (NADP) BOI would establish the Distant NADP as the recommended NADP for all runway ends. This measure would apply to jet aircraft with a maximum takeoff weight greater than 75,000 pounds. For lighter jet aircraft, the continued use of the National Business Aviation Association noise abatement departure procedures would be encouraged.

9 Visual Approach Arrival Altitudes This measure would encourage ATCT to voluntarily route aircraft on the visual approach to Runways 28L and 28R at 5,000 feet MSL until the aircraft begins final approach.

Notes: *Noise abatement measures 1 through 5, 8 and 9 were “approved as voluntary” by the FAA. **Measures 6-7 were disapproved by the FAA and are not included.

Land Use measures, both preventive and corrective, address existing and potential future incompatible land uses surrounding BOI. The owner of the Airport (the City of Boise) can recommend, but does not necessarily have the ability to implement these measures:

Land Use Measures 1 Airport Influence Area

The Boise Airport Commission should recommend to the City of Boise and Ada County to maintain the current AIA boundaries until such time that noise levels require their expansion.

2 Land Use Compatibility Standards in AIA This measure would have the City and County refine land use compatibility standards for the four subdistricts within the AIA.

3 Commercial & Industrial Zoning in AIA The City of Boise and Ada County should maintain existing commercial and industrial zoning within the AIA.

4 Zone for Compatible Use in Apple Street Area Rezone property and land southeast of the airport and east of Apple Street from residential to industrial.

5 Zone for Compatible Use in Gowen Road Area Rezone land southeast of the airport, east of I-84 and south of East Gowen Road from residential to industrial use.

6 Encourage Clustered Residential Development Encourage clustered residential development southeast of the airport within the Airport Influence Area.

7 Maintain Large Lot Residential Zoning Maintain existing large lot residential zoning within the AIA.

8 Maintain Rural Preservation Zoning Maintain existing Rural Preservation zoning within the AIA.

9 Amend Subdivision Regulations and Building Permit Applications to Require Avigation Easements The AIA planning standards require the dedication of avigation easements for all permitted uses in the City and County. In addition, this measure would be required for all (residential and commercial) development within the AIA as part of the building permit process.

10 Adopt Local Building Code Amendments for Noise Level Reduction Construction in the AIA The City and County both lack specific guidance for implementing the requirement for

noise level reduction construction techniques and should adopt noise level reduction standards to supplement their building codes.

11 Adoption of Project Review Guidelines for the City of Boise and Ada County Adopt project review guidelines for rezoning special use, conditional use, planned development and variance applications.

12 Fair Disclosure of Noise Impacts in the AIA Promote means of providing the fair disclosure of potential noise impacts in the Airport Influence Area.

13 Residential Property Acquisition within 65+DNL Contour Acquire 40 existing homes within the 65+ DNL contour of the 2009 NEM.

14 Undeveloped Property Acquisition within 65+DNL Contour Acquire undeveloped land with potential to be developed noncompatibly within the 65+DNL contour of the 2009 NEM.

15 Purchase of Avigation Easements For existing noise-sensitive properties within the 65+DNL contours, BOI would seek to acquire an avigation easement from the property owner. *Homes within the 65+DNL contours of the FAA-accepted (from the 1996 study) that were constructed after October 1, 1998, are not eligible for federal funding support.

16 Purchase of Avigation Easements For existing noise-sensitive properties within the 65+DNL contours, BOI would seek to acquire an avigation easement from the property owner. *Homes within the 65+DNL contours of the FAA-accepted (from the 1996 study) that were constructed after October 1, 1998, are not eligible for federal funding support.

17 Improve City of Boise Application Process To Promote Early Recognition of Airport Influence Area within all Application Processes The City of Boise could improve awareness of AIA at time of application submittal rather than at time of first comment review.

18 Designate Airport Staff Liaison for Planning and Zoning Building Departments of both City of Boise and Ada County Airport staff should play a greater role in reviewing and participating in the development approval process inside the boundaries of the AIA.

Notes: All Land Use measures were “approved as voluntary”, but may or may not have been implemented by the City of Boise or Ada County.

Continuing Program measures are useful for implementing and evaluating the recommended noise abatement and land use measures, and represent strategies that may enhance and/or encourage dialogue between community and the Airport, particularly on airport noise.

Continuing Program Measures 1 Noise Complaint System

Boise Airport would maintain a system for recording and disseminating information on noise complaints.

2 Public Information Program This measure would establish a program to enhance public awareness of aircraft noise issues and the Noise Compatibility Program.

3 Airport Noise Committee This measure would establish a standing committee to encourage dialogue between community representatives, aeronautical users, and the Boise Airport.

4 Aircraft Noise Relations Staff Boise Airport would designate a staff position with responsibility for aircraft noise and land use compatibility issues, in order to facilitate implementation of the NCP measures, coordination with the City of Boise and Ada County, and neighboring communities.

5 Periodic Evaluation of Noise Exposure This evaluation would serve to update the NEMs when needed to account for significant changes in the airport operations or procedures at the Boise Airport. Note: The previous NCP Committed the airport sponsor to updating the NCP as necessary.

Following this meeting, the Study team will collect comments received, and evaluate the Airport’s existing NCP in consideration of the existing and future NEMs. Potential changes to the NCP will be evaluated and identified as either recommended for inclusion, recommended for inclusion with modifications, or removed from the NCP.
