It is the oldest publicly owned airfield in the U.S., with its original dirt runway built in 1928. The airport serves the general aviation and commercial service needs of Stanislaus County. The airport has two runways for general aviation and commercial uses. The longer 5,911 -foot runway serves the commercial uses, while the 3,459 -foot runway is used for general aviation purposes. In 1978, the Stanislaus County Airport Land Use Commission (ALUC) adopted an Airport Land Use Plan for the Modesto City -County Airport. Under various provisions of state law, cities and counties are required to either bring their general plans and zoning and any specific plan into compliance with the adopted County Airport Land Use Commission (ALUC) plan for territory around designated airports_or make specified findings. The purpose of the airport land use plan and the consistency requirement is to eliminate or minimize development around airports that would be subject to significant levels of aircraft noise orwbuld pose a safety hazard to aircraft or occupants of the development in the event of a crash. For the purposes of this General Plan, the City developed.airport,planning area safety zones and standards based on the guidelines in the. 1993 . California Division of Aeronautics Airport Planning Handbook, in: consultation with the Modesto City -County Airport Manager and the California Division of Aeronautics. The City relied on the more current guidelines rather than using the standards in the 1978 ALUC Plan, since the ' most current guidelines represent more recent scientific and planning analysis of risks around airports, and to plan for and anticipate future changes in this area if or when ALUC updates its 1978 plan. See also the 'Aircraft Crash Hazards *section in Chapter 7, Health. and Safety. GOAL 1.H: To regulate future development near the airport to provide for protection of public health and safety. POLICIES 1.H.1. The City shall emphasize compatibility of land uses for both urban development and for airport facilities to ensure the availability of local air transportation services and a quality living environment. 1.H.2. The City shall' allow new development within Airport Safety'Zones (Figure 1-4) according to the standards in Table 1-2. At the discretion of the Ceres Director of Planning and Community Development, an applicant for a permit or other entitlement may be. required to submit survey information sufficient to document the location of a property or development site in.relation to the various Airport Safety Zones. 1-25 Ceres General Plan Pblicy Document r+ N a% TABLE 1-2 RESIDENTIAUNONRESIDENTIAL DEVELOPMENT STANDARDS MODESTO CITY -COUNTY AIRPORT SAFETY ZONES Nonresidential Gross Floor Percentage Residential Density/Intensitr Area"/ Open Flammable/ Airport Safety Zones Densities (max. pop/ Population Space Special Care Hazardous No. (See Figure 14) (max. du/ ss ac) gross ac) fa/ ) (ave. %/ac) Uses` Materials' I Runway Protection Zone (RPZ) None 10 11090 100 Prohibited Prohibited 2 Inner Safety Zone (ISZ) 0.1 (or 1 du/10 ac) 40 270 50 Prohibited Prohibited 3 Inner Turning Zone (ITZ) 2.0 (or 1 du/0.5 ac)` 100 108 20 Prohibited Prohibited 4 Outer Safety Zone (OSZ) 0.4 (or 1 du/2.5 ac)` 100 108 159 Prohibited Prohibited 5 Sideline Safety Zone (SSZ) 0.5 (or 1 du/0.5 ac) 60. 180 30 Prohibited Prohibited 6 Traffic Pattern Zone (TPZ) 6" 150 .70' 10 Conditional Permitted 6A Traffic Pattern Zone (TPZ) 6" 150 70 10 Prohibited Prohibited a Structural occupancy only — determined by Uniform Building Code standards; maybe higher in a single location on the same property or properties if combined into a single development provided maximum not exceeded on a per acre basis. b Example of gross floor area using maximum population per acre assuming 25% site -coverage. c Includes public and private schools, colleges, hospitals, nursing homes, and other similar. uses. d Permitted if in small quantities or if stored in underground tanks. e Portion of 1T7 for Runway IOR-28L designated LDR and zoned R -1 -may be developed to R-1 densities; balance of area south and/or west of River Road not. in the City of Ceres may be developed at a maximum density of 4.0 du/gross acre. i .,f Densities may be transferred from OSZ to portions of same or adjacent property in TPZ; density on portions of property receiving transferred units may exceed density limit of VLDR but may not exceed 6 du/gross acre. g 30% required within the 500 -foot wide strip along center line extended in OSZ. h .

(a) The Legislature hereby finds and declares that: (1) It is in the public interest to provide for the orderly development of each public use airport in this state and the area surrounding these airports so as to promote the overall goals and objectives of the California airport noise standards adopted pursuant to Section 21669 and to prevent the creation of new noise and safety problems. (2) It is the purpose of this article to protect public health, safety, and welfare by ensuring the orderly expansion of airports and the adoption of land use measures that minimize the public's -exposure to excessive noise and safety hazards within areas around public airports to the extent that these areas are not alrgady devoted to incompatible uses. (b) In order to achieve the purposes of this article, every county in which there is located an airport which is served by a scheduled airline shall establish an airport land use commission. Every county, in which there is located an airport which is not served by a scheduled airline, but is operated for the benefit of the general public, shall establish an airport land use commission, except that the board of supervisors of the county may, after consultation with the appropriate airport operators and affected local entities and after a public hearing, adopt a resolution finding that there are no noise, public safety, or land use issues affecting any airport in the county which require the creation of a commission and declaring the county exempt from that requirement. The board shall, in this event, transmit a copy of the resolution to the Director of Transportation. For purposes of this section, 'commission" means an airport land use commission. Each commission shall consist of seven members to be selected as follows: (1) Two representing the cities in the county, appointed by a city selection committee comprised of the mayors of all the cities within that count y, except that if there are any cities contiguous or adjacent to the qualifying airport, at least one representative shall be appointed therefrom. If there are no cities within a county, the number of representatives provided for by paragraphs (2) and (3) shall each be increased by one. (2) Two representing the county, appointed by the board of supervisors. (3) Two having expertise in aviation, appointed by a selection committee comprised of the managers of all of the public airports within that county. 95 (D) Adopt processes for the amendment of general and specific plans to be consistent with the comprehensive airport land use plans. (E) Designate the agency that shall be responsible for the preparation, adoption, and amendment of each comprehensive airport land use plan. (3) The Division of Aeronautics of the department shall review the processes adopted pursuant to paragraph (2), and shall approve the processes if the division determines that the processes are consistent with the procedure required by this article and will do all of the following: (A) Result in the preparation, adoption, and implementation of plans within a reasonable amount of time. (B) Rely on the height, use, noise, safety, and density criteria that are compatible with airport operations, as established by this article, and referred to as the Airport Land Use Planning Handbook, published by the division, and any applicable federal aviation regulations, including, but not limited to, Part 77 (commencing with Section 77.1) of Title 14 of the Code of Federal Regulations. (C) Provide adequate opportunities for notice to, review of, and comment by the general public, landowners, interested groups, and other public agencies. — (4) If the county does not comply with the requirements of paragraph (3) within 120 days, then the plan and amendments shall not be considered adopted pursuant to this article and a commission shall be established within 90 days of the determination of non compliance by the division and a plan shall be adopted pursuant to this article within 90 days of the establishment of the commission. (d) A commission need not be formed in a county that has contracted for the preparation of comprehensive land use plans with the Division of Aeronautics under the California Aid to Airports Program (Title 21 (commencing with Section 4050) of the California Code of Regulations), Project Ker -VAR 90-1, and that submits all of the following information to the Division of Aeronautics for review and comment that the county and the cities affected by the airports within the county, as defined by the plans: (1) Agree to adopt and implement the comprehensive airport plans that have been developed under contract. (2) Incorporated the height, use, noise, safety, and density criteria that are compatible with airport operations as established by this article, and referred to as the Airport Land Use Planning Handbook, published by the division, and any applicable federal aviation regulations, including, but not limited to, Part 77 (commencing with Section 77.1) of Title 14 of the Code of Federal Regulations as part of the general and specific plans for the county and for each affected city. (3) If the county does not comply with this subdivision on or before May 1, 1995, then a commission shall be established in accordance with this article. (e) (1) A commission need not be formed in a county if all of the following condition are met: (A) The county has only one public use airport that is owned by a city. (B) (i) The county and the affected city adopt the elements in paragraph 2 of subdivision (d), as part of their general and specific plans for the county and the. affected city. (ii) The general and specific plans shall be submitted, upon adoption, to the Division of Aeronautics. If the county and the affected city do not submit the elements specified in _ paragraph (2) of subdivision (d), on or before May 1, 1996, then a commission shall be established in accordance with this article. damages to property or personal injury resulting or county's decision to proceed with the action, regulation or permit. (g) A commission may adopt rules and regulations which exempt any ministerial permit for single-family dwellings from the requirements of subdivision (b) if it makes the findings required pursuant to subdivision (c) for the proposed rules and regulations, except that the rules and regulations may not exempt either of the following: (1) More than two single-family dwellings by the same applicant within a subdivision prior to June 30, 1993. (2) Single-family dwellings in a subdivision where 25 percent or more of the parcels are undeveloped. (h) Until June 30, 19.93, no action pursuant to Section 21679 to postpone the effective date of a zoning change, a zoning variance, the issuance of a permit, or the adoption of a regulation by a local agency, directly affecting the use of land within one mile of the boundary of a public airport, shall be commenced in the County of Mendocino. (1) This section shall become inoperative on June 30, 1993, and is repealed on that date. SEC. 2. In enacting Section 21670.3 of the Public Utilities Code pursuant to Section 1 of this bill, the Legislature finds and declares that: (a) The Legislature has not extended the deadlines in Sections 21671.5 and 21675.1 of the Public Utilities Code for the Willits Municipal Airport. (b) This act shall have no effect on the pending litigation brought by the City of Willits regarding the lack of a comprehensive land use plan for the Willits Municipal Airport. (c) The Legislature does not intend to further extend the deadlines in Sections 21671.5 and 21675.1 of the Public Utilities Code for the County of Mendocino. SEC. 3. The Legislature finds and declares that a special law is necessary and that a general law cannot be made applicable within the meaning of Section 16 of Article IV of the California Constitution because of the unique circumstances of the commission in the County of Mendocino. The facts constituting the special circumstances are: There are unique problems involved for the commission in preparing the comprehensive land use plans with sufficient resources and broad public involvement, taking into consideration such factors as the county's natural resources and lands of high scenic values. Airport Owned by a City, District, or County; Appointment of Certain Members by Cities and Counties 21671. In any county where there is an airport operated for the general public which is owned by a city or district in another county or by another county, one of the representatives provided by paragraph (1) of subdivision (b) of Section 21670 shall be appointed by the city selection committee of mayors of the cities of the county in which the owner of that airport is located, and one of the representatives provided by paragraph (2) of subdivision (b) of Section 21670 shall be appointed by the board of supervisors of the county in which the owner of that airport is located. [ Initiation of Proceedings for Creation by Owner of Airport 21673. In any county not having a commission or a body designated to carry out the responsibilities of a commission, any owner of a public airport may initiate proceedings for the creation of a commission by presenting a request to the board of supervisors that a commission be created and showing the need therefor to the satisfaction of the board of supervisors. Powers and Duties 21674. The commission has the following powers and duties, subject to the limitations upon its jurisdiction set forth in Section 21676: (a) To assist local agencies in ensuring. compatible land uses in the vicinity of all new airports and in the vicinity of existing airports to the extent that the land in the vicinity of those airports is not already devoted to incompatible uses.

It is the oldest publicly owned airfield in the U.S., with its original dirt runway built in 1928. The airport serves the general aviation and commercial service needs of Stanislaus County. The airport has two runways for general aviation and commercial uses. The longer 5,911 -foot runway serves the commercial uses, while the 3,459 -foot runway is used for general aviation purposes. In 1978, the Stanislaus County Airport Land Use Commission (ALUC) adopted an Airport Land Use Plan for the Modesto City -County Airport. Under various provisions of state law, cities and counties are required to either bring their general plans and zoning and any specific plan into compliance with the adopted County Airport Land Use Commission (ALUC) plan for territory around designated airports,or make specified findings. The purpose of the airport land use plan and the consistency requirement is to eliminate or minimize development around airports that would be subject to significant levels of aircraft noise or would pose ' -4; safety hazard to aircraft or occupants of the development in the event of a crash. For the purposes of this General Plan, the City developed. airport;planning area safety zones and standards based on the guidelines in the 1993 California Division of Aeronautics Airport Planning Handbook, in consultation with the Modesto City -County Airport Manager and the California Division of Aeronautics. The City relied on the more current guidelines rather than using the standards in the 1978 ALUC Plan, since the most current guidelines represent more recent scientific and planning analysis of risks around airports, and to plan for and anticipate future changes in this area if or when ALUC updates its 1978 plan. ;t See also the 'Aircraft Crash Hazards "section in Chapter 7, Health and Safety. GOAL 1.H: To regulate future development near the airport to provide for protection of public health and safety. POLICIES 1.H.1. The City shall emphasize compatibility of land uses for botKu' roan development and for airport facilities to ensure the availability of local air transportation services and a quality living environniient. 1.1-1.2. The City shall allow new development within Airport Safety•Zones (Figure 14) according to the standards in Table 1-2. At the discretion of the Ceres Director of Planning and Community Development, an applicant for a permit or other entitlement may be required to submit survey information sufficient to document the location of a property -or development site in relation to the various Airport Safety Zones. 1-25 Cees General Plan Policy Daunt ►+ N C� • • TABLE 1-2 RESIDENTIAUNONRESIDENTIAL DEVELOPMENT STANDARDS MODESTO CITY -COUNTY AIRPORT SAFETY ZONES Nonresidential Gross Floor Percentage Residential Density/Intensity' Area"/ Open Flammable/ Airport Safety Zones Densities (max. pop/ Population Space Special Care Hazardous No. (See Figure 14) (max. du/ ss ac) Rross ac) fa/ ) (ave.

(a) The Legislature hereby finds and declares that: (1) It is in the public interest to provide for the orderly development of each public use airport in this state and the area surrounding these airports so as to promote tffd overall goals and objectives of the California airport noise standards adopted pursuant to Section 21669 and to prevent the creation of new noise and safety problems. (2) It is the purpose of this article to protect public health, safety, and welfare by ensuring the orderly expansion of airports and the adoption of land use measures that minimize the public's exposure to excessive noise and safety hazards within areas around public airport's to • the extent that these areas are not alripady devoted to incompatible uses. (b) In order to achieve the purposes of this article, every county in which there is located an airport which is served by a scheduled airline shall establish an airport land use commission. Every county, in which there is located an airport which is not served by a scheduled airline, but is operated for the benefit of the general public, shall establish an airport land use commission, except that the board of supervisors of the county may, after consultation with the appropriate airport operators and affected local entities and after a public hearing, adopt a resolution finding that there are no noise, public safety, or land use issues affecting any airport in the county which require the creation of a commission and declaring the county exempt from that requirement. The board shall, in this event, transmit a copy of the resolution to the Director of Transportation. For purposes of this section, 'commission' means an airport land use commission. Each commission shall consist of seven members to be selected as follows: (1) Two representing the cities in the county, appointed by a city selection committee comprised of the mayors of all the cities within that count y, except that if there are any cities contiguous or adjacent to the qualifying airport, at least one representative shall be appointed therefrom.

J CITY OF CERES GENERALPLIAN Adopted February 24,.1997 t. ----)AIRPORT AREA DEVELOPMENT C� 0 LAND UVAND COMMUNITY DESIGN,ChaP ter 1 The northeastern part of the Planning Area is close to the Modesto City - County Airport, located north of the river in Modesto. Itis the oldest publicly owned airfield in the U.S., with its original dirt runway built in 1928. The airport serves the general aviation and commercial service needs of Stanislaus County. The airport has two -runways for general aviation and commercial uses. The longer 5,911 -foot runway serves the commercial uses, while the 3,459 -foot runway is used for general aviation purposes. In 1978, the Stanislaus County Airport Land Use Commission (ALUC) adopted an Airport Land Use Plan for the Modesto City -County Airport. Under various provisions of state law, cities and counties are required to either bring their general plans and zoning and any specific plan into compliance with the adopted County Airport Land Use Commission (ALUC) plan for territory around designated airports.. or make specified findings. The purpose of the airport land use plan and the consistency requirement is to eliminate or minimize development around airports that would be subject to significant levels of aircraft noise or would pose a safety hazard to aircraft or occupants of the development in the event oT-a crash. For the purposes of this General Plan, the City developed airport planning area safety zones and standards based on the guidelines in the 1993.4 California Division of Aeronautics Airport Planning Handbook, in consultation with the Modesto City -County Airport Manager and the California Division of Aeronautics. The City relied on the more current guidelines rather than using the standards in the 1978 ALUC Plan, since the most current guidelines represent more recent scientific and planriitig analysis of risks around airports, and to plan for and anticipate future changes in this area if or when ALUC updates its 1978 plan See also the 'Aircraft Crash Hazards 'section in Chapter 7, Health and Safety. GOAL 1.H: To regulate future development near the airport to provide for protection of public health and safety. POLICIES 1.H.1. The City shall emphasize compatibility of land uses for both urban development and for airport facilities to ensure the availability of local air transportation services and a quality living environment. 1.H.2. The City shall allow new development within Airport Safety Zones (Figure 1-4) according to the standards in Table 1-2. At the discretion of the Ceres Director of Planning and Community Development, an applicant for a permit or other entitlement may be required to submit survey information sufficient to document the location of a property or development site in relation to the various Airport Safety Zones. 1-25 Cees General Plan Policy Dmume tt .0 72 VerLAJ - 1T .:ji I:'i_..� --'•I �_� =r--- _ - — _r•• •: '.i�• I Jaz.:21 •�..•.IY71:1 _ �•r _..1.1.L ' I lr.~1`: _ _ _.. ef_.. _.• '•rsa.,n.. .l.• 47 Ql.t1��-- ''r-4 so® 7-L= `4, \1.>w/{"•i.s-- �. `'TOSIYRG:_..:-.c... vr.•s•-n..: o:.rcir.7N�:.«'B17iLv :..a..::e�.1�Ir,n:;:re.stt.._.. \ � i \ -� ...

This supplemental allocation, together with the earlier allocation of $41,000 is intended to assist with -funding updates to the Comprehensive Airport Land Use Plans (CLUP) for all four public use airports within the County. -� The combined allocation of $81,000 is considered by the CTC and Caltrans to be up to 90% of the total project cost. Therefore, the match for the total grant amount is 10% of the total project cost or $9,000. This can be a cash match, an "in kind" match, or some combination of both. Although the precise project cost will not be known until proposals are submitted by qualified consultants and a firm is selected, the grant funding that has been approved is expected to be adequate fora majority of the total project. According to previous information provided by the Department of Transportation, the allocated funds are not released as a lump sum. They are released as a reimbursement for. monies which the ALUC pays to the consultant, less the 10% county match and a 10% holdback until the project is completed. Since the funds can only be released in the form of a reimbursement, it is likely that the '98-99 annual budget for the Butte County ALUC will need to be modified in some fashion to ensure that adequate funding is available for up front project costs. In order to complete the grant agreement process, an authorized official of the sponsor identified by minute order or resolution must sign and return an executed copy of the Public Entity's Acceptance of the Allocation for Additional Funds on or before June 18, 1998. The necessary. resolution will be presented to the Board of Supervisors for approval at their regular meeting on June 9, 1998 to ensure that acceptance of the funds is completed well in advance of the deadline. • Butte County • Airport Land Use Commission • 0 2. Status of the RFP for CLUP Preparation - At the time of this report (June 1, 1998), ALUC staff has not received written comments from the Department of Transportation Aeronautics Program regarding that agency's suggestions for changes to the Draft RFP for preparation of the CLUP for all public use airports within the County. The Draft RFP was originally submitted to Caltrans for their authorization on May 6, 1998. Prior to and following ALUC's regular meeting on May 20th, staff has kept in close contact with Christa Engle of the Aeronautics Program to help expedite completion of that agency's response.

Following the receipt of Caltrans' comments on both the Draft RFP and Airport Layout Plans for the Chico Municipal Airport, Paradise Skypark Airport and Ranchaero Airport, staff will finalize the RFP and distribute it to a list of qualified consultants. The tentative due date for proposal submittal is one month following the release of the RFP.
