The project is surrounded by existing and approved SR -1 (one acre per home) residential development which is built or being built at equal or greater density to the project, making this project truly an "infill" project even though it does not meet the ALUC criteria for such. 2. The project is proposed for development at an average density per acre of about 1.3 acres per residence which is well below the North Chico Specific Plan (N CSP) SR -1 zoning minimum size lot per residence of one -acre, by subdividing 43.83 acres into 30 one -ace lots. 3. The 5 -acre park ,%vas moved from the north end of the site where it was tentatively proposed to be located under the NCSP, to a better location along the southern boundary of the site. bordering Keefer Slough where the park will serve the multiple purposes of creek corridor • wildlife habitat and recreational trail expansion, flood plain protection, improved waste disposal,. and could provide.an emergency landing area before aircraft reach the subdivision. Butte County Board of Supervisors. March 27, 200.1 Page 2 I This relocati . on is supported bythe Chico Area Recreation* Park District (CARD) for these same reasons. Airport Land Use Consistency On September 20, 2000, theButte County ALUC reviewed the project for consistency with the CMA under ALUC's Comprehensive Land Use Plan Update, adopted December 29, 1999 (1999 CLUP). The 1999 CLUP recommended a minimum..2. 5 -acre parcels per residence, despite the fact that the Butte County Board of Supervisors had previously approved 1 -acre minimum parcel sizes for this site under the NCSP. The Schuster project has been designed to be consiste . nt with the NCSP I acre parcel sizes approved by the Board. For the following reasons, the proj ect will pro,6de for the orderly development of the CMA and the area surrounding this airport so as to promote the overall goals, and objectives of the California Airport . Noise Standards and to p�event the creation of new noise and safety problems, as well as protect public health, safety, and welfare by insuring the orderly expansion of the CMA by the adoption of land use measures that minimize the public's exposure to excessive'noise and safety hazards within areas around that airport, as required by California's Public Utilities Code 21670, et seq. (PUC): Conditions of approval can be adopted to ensure airport compatibility and consistency. 2. The project is located further away from the CMA than the Stephens residential development project (Stephens) which Was approved in 1998 by the Board of Super -visors. pursuant to findinas and overruling considerations thereafter upheld by the Butte County Supenior Court as legal and va . lid acts by the Board. The Schuster project i S' located just one-quarter mile immediately west of Stephens. Because of this, most of the Board's findings supporting approval of the Stephens project are relevant to Board approval of Schuster, and are attached and incorporated by reference into. this letter for t he Board's consideration. (Attached.) 70% of the project lies within the CalTrans Safety and Over Flight: Approximately ALUC's 'Traffic Pattern Zone' (TPZ). The remaining approximate 30% lies entirely within self -devised Over Fli-ht Protection Zone "B". (Attached.) According to the 1993 CalTrans Handbook at page 9-16, the discussion of "Acceptable Forms of Development'.' concerning C' 0 the TPZ concludes that "the potential for aircraft a cidents is relatively low and the need f r land use restrictions is minimal . . . Typical -residential subdivision densities of 4 to 6 dwelling units per a&e are acceptable from a safety perspectiv6 ... Even higher densities mav be r easonable, especially if development is clustered to provide open space . . ." Thus, ALUC's limit of one dwelling unit per 2.5 acres far exceeds CalTrans expert 4.. . 0 Butte County Board of Supervisors March 27, 2001 Page 3 recommendations and is'unnecessary. The proje . ct's 1 -acre pe . r dwelling density fal Is well. within CalTrans allowable levels of 4 to 6 dwellings per acre. The Over Flight Protection 1 0 Cp Zone"B" wholly -created by ALUC which purportsto prohibit new single family dwellings is not one of the six zones recognized by . CalTrans as necessary to protect airport operations within the meaning of the PUC. Furthermore, the project proponent proposes to relocate and expand a 5 -acre park site from the north end (TPZ) of the site to the. south end.(Zone "B") of the site where it will provide a permanent, nearly 7 -acre area of. open'space where no single family dwellings will be built, Which furthers th6 goals and objectives of the PUC.. In fact, at this location, the park could provide for 'greater- public safety protection by' providing, an emergency landing area b I I C� 0 efore aircraft fly over the subdivision, in the event it is needed. There . fore, the project does not -create safety . problems or result in public exposure to excessive safety or over flight hazards. 4. Noise: The 1999 CLUP "Future CNEL Noise Contours" exhibit. (attached) showg the entire project site lies well outside.of the 55 dB CNIEL line. According, to CalTrans, exposure to outdoor noise of 55 dB CNEL or less, which is comparable to background music or a dishwasher running; in the next room, is considered "quiet" and fully compatible with single family dwellings. (CalTrans Handbook, Chapter 6.) Even single -event noise such as aircraft engine testing i s determined to result in less than a 2% chance of sleep disturbance at this location at ni-ht time by CalTrans. Therefore, the project does not create noise problems or result in public exposure io excessive noise hazards. Airspace Protection: The CalTrans Handbook recommends that "airspace obstructions" such as tall buildings and other land use characteristics which pose "other potential hazards to, fli alit by attracting birds or creating visual or electronic: interference with air navi cation" be avoided by development in proximity to airports. (CalTrans Handbook, Chapter 3.) The Schuster project proposes I single family residential dwellings,and related land- uses which, by their nature, and by existing design standards are generally limited to heights below 35 feet and are otherwise designed so as not to pose a potential airspace obstruction, nor attract birds, nor create visual or electronic interference to air navigation. Therefore, the project does not create a threat to airspace.protection. V �4 (IT' Butte County Board of Supervisors March 27, 2001 Page 4 Conclusion Basedupon all ofthe substantial fa6tual evidence stibmitted-into,.the record, durincy the course of public hearings upon the Schuster application prior to- and including Board of Supervisors hearings, we ask that the Board of Supervisors (1) approve the Schuster project by.a 4/5's vote, (2) overrule the A-LUC inconsistency determination, and (3)'make findings in fulfillment of the requirements of Public Utilities Code Section 21670, et seq., that approval of this project provides for the orderly development of the Chico Municipal Airport and the area surrounding the airport so as to promote the overall goals and objectives I of the California Airport Noise Standards adopted pursuant to the PUC, and that the project prevents ihe.creation of new noise and safety problems. Furthennore, we ask that the Board acknow ' ledge that approval of the.Schu�ter project adequately protects the public health, safety and welfare by ensuring the orderly expansion of the Chico Municipal Airport for the reasons described in this.letter, in staff reports, and in all other submittals and exhibits which explain how the public's exposure to excessive noise and'safety hazards around the Chico Municipal Airport are minimized. and which demonstrate.that adequate over flight and airspace protection have been taken into consideration. Thank you very much for your consideration of this very important request to approve Mr. Schuster's Pheasant Landing project by the 4/5's vote of the Board which is required by state law.

Consideration of overriding findings for ALUC consistency findings. G.P.: Agricultural Residential APN: 047-250-141 Location: On the west side of Hicks Lane immediately adjacent to the Chico Municipal Airport, approximately between Keefer Slough and Mud Creek Parcel Size: A 230 acre portion of a 300 acre parcel Related Projects: Development Agreement 99-01 SUMMARY: The Butte County Planning Commissions,recommendation for this project is still a denial recommendation. If the Board of Supervisors chooses.to approve the amendment to the North Chico Specific Plan (NCSP), the Commission recommends , the use of a Development Agreement to ensure certain conditions are met. Additionally, the Board must make findings to override the Butte County Airport Land Use Commission's determination that the project is not consistent with the recently amended Chico Municipal Airport Environs Plan. Due to the requirement of overriding findings, the Board mus�t approve this project by a 2/3 majority . DISCUSSION: On October 21, 1998 the Butte County ALU.Q approved an amendment to the 1978 Chico Municipal Airporl Environ� Plan (CMAEP). The amendments became effective immediately upon adoption. These changes to the airport plan affect the Stephens property and therefore this requested amendment to the North 'Chico Specific Plan (NCSP). The amendments to the CMAEP included the adoption of Overflight Protection Zones "A" and "B". Zone "A" prohibits the establishment of all new residential dwellings and zone "B" prohibits all new single family dwellings but allows multi -family structures. After adoption the amended plan, the County has 180 days to either bring their general plan and any specific plans into conformity with the airport plan or make overriding findings. Theprocedure for an override is spelled out in detail in the Cal Trans Division of Aeronautics Airport Land Use Planning Handbook. Enclosed as attachment "A" are the -pertinent override sections. Based upon the amendment to the airport plan, the Board referred this project back to ALUC for bonsistency findings. ALUC heard the project on November 18, 1998 and found that it was inconsistent with the amended plan. Specifically, ALUC found that the recently adopted overflight v Butte County Department of Development Services Agenda Report a K'Schuster HorresftrM Chico Sub&ision (6096-W01)*enda reW (bos),I*pd 1 . . M1 2.24PM - zones A & B prohibit new single family residences in orderto minimize'the public's exposure to excessive noise and safety hazards in area that are subject to the most intense overflight activity. This includes flight activity from several different i types of heavy aircraft.. Noise exposure to the i site comes from general aviation activities but the site is also subject to excessive noise levels during'' CDF response to campaign ' fires and during military aircraft operations. Additionally, Aero Union. routinely does. engine run -ups during the nighttime hours of the summer months when the aircraft are most heavily used. The findings also state that Stephen . s project site is located in *a'n are . a that has an elevated likelihood of being impacted by both arrival and departure aircraft accidents. The. full findings and supporting data is enclosed as attachment B. BOARD OPTIONS: In making a decision on the is project, the Board should. consider"'fh-e - ----- recommendation of the Planning Commission, which was to.deny this project. The Commission's - recommendation was based upon two main points., that an increase in residential dwellings in this area represents a potential conflict with the Chico, Municipal Airport, and; that the development potential of -the Stephens property was not adversely affected by the NCSP, even though 103 acres was designated open space. It should also be noted that, in addition to previous correspondence from a variety of interests favoring,denial of the project, t he County has received additional letters from local residents, the City of Chico, and Aero Union Corporation strongly opposing residential development for this site. If a motion for denial is made no specific findings are required as this' is a legislative act. If the Board chooses to make a motion for approval, required findings and overriding findings must be made and recommended findings area provided as stated below: Approval Motion: Section 1:' Environmental Findings. A. An Environmental Impact Report has been adopted and certified for the North Chico Specific Plan (NCSP) which identified significant environmental impacts and provided mitigation measures to address those impacts. The EIR also identified significant unavoidable impacts for which no mitigation Was available; traffic and circulation, air quality impacts and land u ' se impacts. However it was found that the NCSP had significant benefits and overriding findings were adopted as fully discussed in Resolution 95-47. An Initial Study,was completed in compliance with the California Environmental Quality Act for the Stephens proposed amendment to the North Chico Specific Plan and rezone.. No new potentially significant environmental effects were identified that were not identified and mitigated as part of the Stephens Negative Declaration or Final EIR (FEIR) for the North Chico Specific Plan or overridden at the time of adoption of the NCSP. Impacts that were previously identified as significant unavoidable impacts have not changed or been exacerbated because the Stephens project does not exceed any of the development assumptions and thresholds evaluated in the NCSP as witnessed below: The NCSP EIR identified an increase of approximately 63,000 daily trips based upon Ahe development of 3,093 new dwelling units and approximately 267 acres of new industrial development. As adopted, the plan reduced the number of dwellings to approximately 2,803 and the number of developable acres of industrial land to 247 acres. With the adoption of this amendment, the m Butte County Department of Development Services Agenda Report a USchuster Hornesftm Chic— SubdM�n (6096-0001)% agenda repw (bos).wpd 2 31WO 12:24 Ki residential buildout of the Plan will be 2,896 dwelling units, well within the number cont*mplat6d by the certified FEIR; e 2. The impacts to air quality were based upon the creation of 3,093 new dwelling units and approximately 267 acres of new industrial development.. As adopted the plan -provided for approximately 2,803 new dwelling units and estimates the number of developable acres of.iridustrial land to be,247- acres. With the'.-.' adoption of this amendment ' ''the residential buildout'of the Plan will be 2,896 dwelling units, well within the number contemplated by the certified. FEIR; and, The loss of open space was identified as a significant unavoidable impact of the�. NCSP. The retained open space within the NCSP was -intended to help maintainthe rural atmosphere that currently exists, and was 6. component of an.' overall environmental strategy to mitigate .*development within the �NCSP area as detailed on page's 6-13 through 6-16,. 7-5, 8-3, 13-7, and.1 5-3 of the NCSP draft EIR and FEIR. The 103 acres identified on the Stephens' property as open space by the NCSP, will be 'retained for that purpose and will not be reduced in size. B. An Initial Study was completed in compliance wi ' th the California Environmental Quality Act for the proposed Development Agreement and no potentially significant environmental effects were identified; and C. The Board of Supervisors has - independently reviewed, analyzed and considered both proposed Negative Declarations prior to. making its decision on the amendment to the NCSP and rezone and the Development Agreement; and said Negative Declarations reflect the independent judgement of the County of Butte; Section 2: General Plan Consistency Findings. A. The proposed amendment to the North Chico Specific Plan and associated rezoning is consistent with the policies-, including the text and map, of -the Butte County General Plan as discussed below: 1. The Butte County General Plan Land Use -Element designates the 230 acres north of Mud Cre i ek as Agricultural Residential. The maximum development potential allowed by this designation is 1 dwelling unit per acre. The net result of the proposed amendment to the NCSP is the develop mient of up to 160 dwelling units within the boundary of the 230 acres for an average density that is consistent with,the General Plan Land use designation. .. Specific policies in support of the proposed amendment include:- CA.e. - Encourage urban expansion toward the least productive soils. The site contains marginal agricultural soils capable of supportin g only grazing or limited agricultural,use�. v Butte County Department of Development Service s Agenda Report a U.Schuster McmesWorth Ch,co Subdivisien (609"001)%agenda repon (bcs).-mpd 3, M 12.24 PM 0.1.b. Provide a diversily. of housing sites va[ying in ize. density and location'. sl The PD combining zone will provide the ability to offer more housing - choices in the NCSP. D.2.a. Correlate residential densities to soil. SIODe and other nqti irql ctifim characteristics. The site has few limiting characteristics. Sewage disposal. and drainage are two areas that cou,ld potentially limit dieveloipirh 6 n*t.'* However, the 103 acres of open'space acreage is available to overcome these limitations. D. 2. c. Relate residential densities to intensily and compatibility of adiacent uses. The resulting residential development will, not be as dense as adjacent residential uses in the Village"core and will provide a suitable transition to the 1 acre parcels to the north and west. D.2.d. Balance residential densities with traffic -carrying capacities of existing and groposed circulation plans. The proposed circulation - plan and improvements proposed by the NCSP will accommodate the additional traffic generated by this project because the improvements were based upon a greater number of dwelling units than ultimately approved by the NCSP, including the proposed amendment. G. 5. b. Prevent development and site clearance other than river bank protection of marshes and significant riparian habitats. The Development Agreement provides. for riparian protection and'enhancement through the use of creek side setbacks and vegetation plantings. H. 3. a. limit development in areas with siqnificant drainaqe and floodina i)roblems until adequate drainage or flood control facilities are Provided. The incorporation of drainage conditions to reduce peak project site runoff to 10% below pre -development conditions will serve to reduce downstream flooding. An easement along the westerly property boundary will also be deeded to the County in order to provide for future drainage -improvements; that will allow the transfer of flood waters from. Keefer Slough to Mud Creek., This is a critical component I in solving downstream flooding problems on Keefer Slough. 10.0 Provide for a safe and convenient bicycle transportation system which is integrated with other transportation modes. Pedestrian trails and bicycle paths are integrated as part of the NCSP and are also required.as part of the Development Agreement. Section 3: Airport Consistency Findings. 1978 Chico Municipal Airport Environs Plan A.

The detailed findings are'contained in a,report from the ALUC dated December 9, 11997;�and B. In a public hearing'held on December. 11, 1997, the Planning Commis'sidn' recommended that the applicants revise their project to preclude the pla.ceme ntofany residential units within the existing open space lands, addressing one of' A'LUC's concerns; and C. In a letter dated February -6, 1998 the Stephens' attorney responded to the ALUC findings and provided information intended to support a finding that the project was consistent with the Chico Municipal Airport Environs Plan. The letteralso contends that all of the environmental and project consistency findings made by ALUC we're either unsupported by substantial evidence in the record and/or were contrary to law and thus invalid. and that approval of the project does hot require overriding finding S, adopted'by a 2/3 majority vote; and D. In a letter dated April 28,1998, the Stephens'aftorney further responded to the ALUC finding by demonstrating that approval of the project should not require overriding findings adopted by a 2/3 majority vote, because the amendment to Ahe Specific Plan and the rezone remain completely consistent with all relevant findings and the statement of , overriding considerations previously adopted by the Board -.of Supervisors on March 28, 1995, when it approved.the NCSP and.at that time adopted Overriding Findings Regarding the Airport, Land Use Commission finding of inconsistency for the NCSP; and E. In a public hearing held on February 12,1998, the Planning Commission reviewed a project that - was revised in accordance with the Planning Commission's recommendations made at the December 12,1997 meeting, to propose development of up to 160 dwelling units without building upon'any land within the NCSP open space designation; and F. Prior to the Board of Supervisors hearing on June 23, 1998, the applicants again revised their project to address the balance of ALUC's concerns related to the future expansion of the Chico Municipal Airport, and agreeing to limit development of the site to no more than 126 dwelling units until a new Comprehensive Land Use Plan (CLUP) was prepared. Upon adoption of the new CLUP, up to 34 additional dwelling units out of the total maximum of 160 dwellings. could be applied for subject to a finding of consistency with the new CLUP. At the June 23,hearing, the Board of Supervisors recommended that a0evelopment Agreement be used to clarify and Vest both the applicants' and, the County's rights and obligations for development of the property under the revised amendment to the NCSP and the rezone; and G. At a public hearing held on August 19, 1998, the ALUC reviewed. the Development Agreement proposed for the project and found the project as proposed on that date to be both consistent with'. the. Chic 6- Municipal Airport Environs Plan -as well as compatible with the viable, responsible operation of the Chico Municil5al Airport. A finding of Development Agreement consistency amounts to a consistency finding for w Butte County Department of Development Services Agenda Report n k1schuster Horms'North Chico Subdivision (6096-0001)lzgenda report (bos).wpd 5 1W 2:24 PM 0 the entire Stephens project because the Development Agreement controls all aspects of development under the amendment to the NCSP and the rezone for the project site including, the number and, density of dwelling units, precise approval of development and open space areas, and timing of the construction of the dwelling u.91ts and 'public improvements. The ALUG consistency finding Was based upon one (1) required conditio,n, eight (8) recommended conditions and two (2) reco * mmend.6d changes to' the Development Agreement, the details of which are contained' in ALUC's.,- consistency finding report dated August 20,1998, all of which conditions.,tnd changes have been incorporated into and made a part of the Development Agreement and therefore also apply to the amendment to the NCSP and the rezone; and H. At a public hearing held on August 27, 1998,'the PlanningCommission re I viewed the Development Agreement and proposed further recommended changes' to the document, none of which limited the effectiveness of ALUC's conditions or the consistency finding. Planning staff and the Planning Commission. recommended that ' the Board of Supervisors enter into Ihe Development Agreement if the amendment to the NCSP and the rezone are approved; and 1. Based upon the several significant limitations upon the amendment to the NCSP and the rezone which are made binding upon the applicants under the Development Agreement that was found to be consistent with, the Chico Municipal Airport Environs Plan as well as compatible with. the viable, responsible operation of the Chico Municipal Airport, the Board of Supervisors4may approve'the Development Agreement, amendment to the Specific Plan and rezone by a simple majority vote in compliance with Public, Utilities Code Sections 21670, 21676, et seq.; and J. Because these same numerous modifications to the project overall have brought the entire project into compliance with the March 28,1995 Overriding Findings Regarding the Airport Land Use Commission, adopted by the Board of Supervisors by a 2/3 majority vote when it approved the NCSP, the requirements of Public Utilities Code Sections 21670, 21676, et sbq.,- have already been legally satisfied. Therefore, the Stephens'Development Agreement, amendment to the NCSP and rezone provide for the orderly development, expansion, and long-term viability of the Chico Municipal Airport and orderly development of the area surrounding the airport in the same manner as the NCSP such that the Board of Supervisors hereby makes the following same findings as were made for the NCSP, th*at: 1. . Residential land uses, at densities greater than one (1) unit per acre, are not allowed within 3,700 feet from the centerline of the main runway, as shown on the Alternative Land Use Map in the FEIR, thus limiting the potential for complaints.of incompatibility with airport uses; 2. Open space has been planned for the area westerly of the Clear Zone, northerly of Mud Creek, as shown.on the Alter�ative Land Use Plan in the FEIR, further reducing the potential for complaints of incompatibility with airport uses; I .

The Specific Plan provides for airport protection measures as part of the Development Regulations in Chapter 7 of the Specific Plan, pages 7-6 and 7-7. K As with the NCSP, theStephens'Development Agreement, amendment to the NCSP and, rezone also protects the public health, safety, and welfare by minimi . zing exposure to excessive noise and safety hazards within areas adjacent to the Chico; Municipal Airport as follows: Avigation easements are required, as indicated on page 7-'6 of the'NCSP text, for all residential development within the Plan area; 2.

Municipal Airport Clear Zones and very low in the vicinity of the Village Core, which'vicinity includes theStephens property; 4. The Compan . son of Flight Tracks and School Sites, together with the testimony pertaining thereto at the Board of Supervisors public hearing on January 10, 1995, by the Countys consultant, Steve Honeycutt, indicates that aircraft on flight tracks at Chico Municipal Airport are at a sufficient flight distance and altitude so as to not expose the high density residential and the elementary school sites to excess.ive noise or safety hazards..: These aircraft flight tracks are also at a sufficient flight distance and altitude so as to not to expose the Stephens property to excessive noise or safety hazards; L. Furthermore still, because the applicants incorporated into the Development Agreement, amendment to the NCSP and the rezone, the one required condition that the minimum lot size for any parcel is not less than 8,125 ' square feet if served by individual wells and on-site sewage disposal systems, or 6,500 square feet if public sewage disposal service,is provided, the effect of ALUC's consistency finding is that the entire project is consistent with the Chico Municipal Airport Environs Plan and that the project is compatible with the viable, responsible.operation of the Chico Municipal Airport. . a Butte County Department of Development Services Agenda Report a .

The Development Agree ment shall stipulate that the tentative subdivision map to create 34 DTUs within the 126 acre portion of the subject property is I to be reviewed by the Airport Land Use Commission for consistency with the Updated CLUP for the Chico Municipal Airport when adopted or the existing Chico, Municipal Airport Environs Plan,. if the CLUP update has not been completed within 24 months (subsequently changed to 30 months by the Planning �Commissi ' on) from the date that the Development'Agreement is executed.' If the proposal to create the 34 DTUs within the 126 acre portion of the 1property is found by the ALUC to be inconsistent with the applicable Airport Land Use Plan, the property owner/applicant waives their right to request that the Board of Supervisors adopt Overriding Findings. to approve the project. However, if a finding of inconsistency is made by the ALUC to create the 34 DTUs within the 126 acre portion of the subject property, the property owner/applicant may submit a subsequent tentative subdivision map to create the 34 DTUs within another property that is located within the North Chico Specific Plan Area. The tentative subdivision map, for such a transfer must also be reviewed by the Airport Land Use Commission for consistency with the applicable Airport Land Use Plan. The property owner/applicant agrees to waive their right.to request that the Board of Supervisors adopt 'Overriding Findings to approve the transfer of the units to another property if that proposal is also found to be inconsistent by the ALUC. N. On October 21, 1998,* the Butte County Airport Land Use Commission (ALUC) amended the 1978 Chico Municipal Airport Environs Plan finding that the standards within the plan were not compatible with the intent of the State Aeronautics Act and the guidelines contained in the CalTrans' 1993 Airport Land Use Planning Handbook. The amendment adopted an Overflight Protection Zone (OPZ) and Outer Safety Zone. Under the amendment, the Stephens property is located in both an Overflight Protection Zone "A" and "B". Said zones "A" and "B" purport to prohibit new single family dwelling uses. If the Stephens'- project, were brought back before ALUC for consistency findings, it is acknowledged that the project would not, be found compatible with the amended plan and overriding findings would be required to approve the project. The Boa ' rd hereby makes the findings required by Public Utility Code 21670 and 21676 et seq., as supported by those specific findings set forth in Sections J through M above, which findings are incorporated herein and support the conclusion that approval of the Stephens' project, as conditioned, will not create any new noise and safety problems near the Chico Municipal Airport. Furthermore, the approval of the Stephens' project, as conditioned, includes land use measures that minimize the public's exposure to excessive noise ' and safety hazards. These conclusions are further supported by the detailed information contained in the "Exhibits in the Administrative Record," dated June 23, 1998, submitted by the applicant. Therefore, the approval of the Stephens' project is consislent with the Butte County Department of Development Services Agenda Report n KI.Schuster FiorriesWorth Chico Subdivision (6096-000 1)*enda report (bos). wpd 9 3,W1 2.24 PM 0 -purposes of Article 3.5 of Cha0ter4 of Part I of Division 9 of the Public Utilities Code, as stated in Section 21670. 0. If the Board of Supervisors, pursuant to Public Utilities Code Section.s 21670 and 21676, in the. alternative, approves the Development Agreement, amendment to the NCSP and the rezone by a 2/3 vote, the Board of Supervisors hereby makes Sopc' " ific Findings that the Stephens' project is consistent with the purposes of Public Utilitie si Code Section 21670,,based upon all of the findings previously described above. Override findings to the.1998 amended Chico Municipal Airport Environs Plan On October 21,1998,ALUC purported to adopt an amendment to the 1978 Chico Municipal Airport Environs Plan (CMAEP) (Because there is significant legal uncertainty as to whether the October 21 amendment is legally in force and effect because of the manner by which ALUC provided public notice prior to their adoption of the October 21 amendment to the' CMAEP, the Board of Supervisors. has also made the above findings pertaining to ALUC's prior consistency findings under the 1978 CMAEP for the Stephens' project.). On November 18, 1998, ALUC reviewed the Stephens' application for consistency with the 1978 CMAEP as amended on October 21, 1998. . While the 1993 Airport Land Use Planning Handbook ("CalTrans Handbook") identifies. four functional categories for determining airport land use compatibility: Safety, Overnight, Noise and Airspace Protection, on November 18th, ALUC reviewed the Stephens' project application for' consistency with the amended CMAEP regarding policies to address Safety and Overflight Protection. However, because Exhibit B to ALUC's October 21 amendment to the CMAEP and "Other Commission Comments" included- outside of 4he- Project Consistency Findings in the November 18 ALUC ' review of the Stephens' project, discuss noise compatibility and allude to airspace protection, the following override findings address all four issues: Safety, Overflight, Noise and Ai ' rspace Protection, to factually demonstrate that approval of the Stephens' project by the Board of Supervisors rTieets all Public Utilities Code Section 21670 and 21676 requirements - A. Safety and Overfliq ht. On October 21, ALUC purported to adopt an Overflight Protection Zone (OPZ). with two subzones identified as Zone A and Zone B, both of which are stated to prohibit new single-family residential development entirely within their boundaries. ALUC Exhibit A (Drawing CIC -14) depicts the OPZ. Exhibit AJs designed to depict the OPZ identified in Exhibit 111-1, "2010 Airport Noise Compatibility Plan," of the FAR Part 150 Airport Noise Compatibility Program and Environs Plan for the Chico Municipal Airport (FAR Part 150). The four safety zones depicted on page 9-16 of the 1993 CalTrans Handbook have also been overlaid onto this exhibit. The Runway Protection Zone (1),* Inner Safety Zone (2), and Inner Turning Zone (3) are all contained within the OPZ. The only CalTrans safety zone which ALUC states the OPZ does not incorporate is the Outer Safety Zone (4). Because the CalTrans Handbook at page 9-16 indicates that there are a total of six safety zones, including a Sideline Safety Zone (5) and a Traffic Pattern Zone (6), the OPZ must therefore also incorporate the Sideline Safety Zone (5) and -traffic Pattern Zone (6) sincethe only CalTrans / a Butte County Department of Development Services Agenda Report m K:'SchuSter Homesftr1h Chieo Subdwsim (60%0001)%agenda repcn NS).wpd 10 3/&012:24 PM safety zone which. the. OPZ does not incorporate, is the Outer Safety Zone (4) according to ALUC's October 22.1etter to Thomas Parilo (pps. 2-3). .2. Approximately one.third of the northern portion of the Stephens' property lies.. within the Inner Turning Zone as identified in Drawing -CIC-14 and in the' CalTrans Handbook in Figure 9G. it page - 9-16. In its discussions of nTh6*1-...-*,-" Concept of Acceptable Risk" and "Protecting People and Property'on" th6'-,,, Ground" (Chapter -9), the CalTrans'Hand book. states on page 9-22 urid , et "Acceptable Forms of Development" that for the Inner Turning Zone,'"[t]he minimum lot size criteria for residential uses should be somewhere in.the range -..'- encompassed by the inner and outer safety zones; that is, between 2 and 10 acres." To assure Chico. Municipal Airport safety and ov6rflight compatibility, the Board requires that the Stephens' Development Agreement incorporate the following language from the August 20, 1998 ALUC Consistency Findings, requiring that: Residential densities within 'the Inner Turning Zone shall be restricted to the densities recommended within the 1993 Airport Land Use Planning Handbook (no more than one dwelling unit per two acres) to.protect the safety of aircraft and persons on the ground. Based upon CalTrans criteria, the Board of Supervisors has determined that one residential dwelling unit per two acres on the Step hens'*p rope rty within the Inner Turning.Zone is an acceptable form of development, -as recommended in the CalTrans Handbook'on pages 9-21 and 9-22.'For this reason, a complete prohibition on residential development within'Zones ' A and B on the- Stephens' property is unnecessary to satisfy the requirements of Public Utilities Code Section 21670. 3. For the remaining majority of the Stephens' property which is located within the Traffic Pattern Zone as identified in Drawing. CIC -14 and in the CalTrans Handbook in Figure 9G at page 9-16, the discussion of "Acceptable Forms of Development" states that: Traffic Paftern Zone -- Within other portions of.the airport area routinely overflown by aircraft, the potential for aircraft accidents is relatively low and the need for land use restrictions is thus minimal. . . . Only very large assemblies of people in the 150 or,more people -per -acre range -- need to be avoided. . Typical residential subdivision densities of 4 to 6 dwelling units -per -acre are acceptable from a safety perspective. . . . Even higher densities may be reasonable, especially if development is clustered to,provide open space.... The Stephens' Development Agreement also incorporates from the August 20, 1998 ALUd Consistency Findings, the requirement that: "[R]esidential densities .within the Traffic Pattern Zone shall not exceed 6 units per acee." Butte County Department of Development Services Agenda Report a K.%Schuster HornesWorth Chico Subdivision (609&0001)%agenda report (bos).wpd M1 Z.24 PM Based upon CalTrans criteria, the Board of Supervisors has determined that six residential dwelling units pera c*re on the ' Stephens' property within the Traffic Pattern Zone is an. acceptable form of development satisfying the requirements. of Public Utilities Code Section 21670, as recommended in the CalTrans Handbook on pages 9-21 through 9-23.. For this reas on, a. complete prohibition on residential development within Zones A and Bon the Stepheris. property. is unnecessary. 4. The Stephens'Development Agreement incorporates an amendment to the text of the North Chico Specific Plan (NCSP) adding a PD -Planned Development-.. 7 Combining Zone which requires that a minimum of 25% of the gross acreage within the'PD designation will befetained as open space and that residential dwelling units will be built upon a vahety of lot sizes, including the clustEdng of residential dwelling units. The retention of open space and the. use of clusteMg residential dwellings are recommended by CalTrans as strategies to improve the compatibility of residential development within all CalTrans safety zones, including the Inner Turning Zone and Traffic Pattern Zone, within the airport environment. The CalTrans Handbook, on. page 9-24, in its discussion of "Clustering Versus Spreading of Development,". states that: . . . Mradeoffs between safety and economic concerns usually dictate some amount of development near airports.... The premise behind the concept of clustering is that, in most Off -airport mishaps, the aircraft are under some degree of control when forced to land. Clustering thus allows a greater,'amount of open space towards which the pilot can aim. In addition to reducing the risks for people on the ground ', open space also- provides benefits for aircraft. occupants. Regarding the Inner Turning Zone, the CalTrans Handbook states on page 9-27, "[a]t least 15% to 20% of the zone should remain as open space." Regarding the Traffic Pattern Zone, the CalTrans Handbook states on page 9-27, ". . . 10% to 15% useable open space or an open. area approxima , tely every 1/4 to Y2mile should be provided.". Because the new PD zoning and the Development Agreement both require the retention of 25% of the gross acreage as open space, the Board of Supervisors hereby determines that the goals and objectives of Public Utilities Code 21670 to minimize the public's exposure to excessive safety (a'nd. noise) hazards are already accomplished by the Stephens' project design. In fact, the new PD zoning, NCSP amendment and the Development Agreement together now, for the first time, allows clustering of dwellings, variable lost sizes and requires much greater open space retention, actually making residential development upon the Stephens' property more airport compatible than under the prior zoning for the property. 5. In Exhibit D (Drawing CIC -17) and Exhibit E (Drawing CIC -18) to the ALUC October 21, 1998 action, ALUC alleges that these exhibits -- which were adapted from the CalTrans Handbook and the University of California Berkeley, Institute of Transportation Studies (1993) -- identify areas with particular safety-related concerns.

As described above, on November 18, 1998, ALUC reviewed the Stephens' application for -consistency with the October �1, 1998 purported amendment to the 1 ' 978. CMAEP. The Overflight Protection Zone (OPZ) adopted as part of these amendments seeks to prohibit new single-family residential development. Based solely upon unspecified information allegedly from the Chico.Municipal Airport tower, ALUC's unsubstantiated opinion is that an unquantified number of heavy military aircraft and firefighting air tankers make unscheduled low -altitude approaches, which operations involving these types of aircraft can be particularly annoying to residents because of their size. Based solely upon this statement unsupported by substantial evidence in the administrative record, ALUC-concluded that the only effective strategy is to prohibit residential development because the CalT ' rans Handbook 'recommends that the ideal strategy cited on Page, 3-9 of the handbook 'is to avoid development of Butte County Department of Development Services Agenda Report s K:Schustor HomsXcrlh Chico Subdimsion (6096-0001)�zgenda repon (bos).wpd 13 31&01214 PM Runways of 6,000 Feet or More," in the CalTrans Handbook are. referenced to explain the meaning 6f ALUC Exhibits D and E depicted in Drawings CIC -17 and. CIC -18, talTrans Handbook states. on pages 8-32 and 9-26 -that, "Accidents in which aircraft are under control are bunched relatively close to the runway ends mostly within, about 3,000 feet -- both for arrivals and deoartu'res.'':, These observations lead to the'following suggested criteria: ...... Inner Turning Zone 15% to 20% ... open space- . . Traffic Paftern Zone 10% to 15% usableopen space. . . As described previo'usly.ih the�e findings, particular safety-related concerns are minimized by design requirements for the Stephens' project so that the Stephens' property no longer needs to be identified as an area with particular safety-related concerns. For.-: example, residential land uses at densities greater than one (1)- unit per acre, - will not be allowed within 3,700 feetfrorn the centerline of the existing main runway, thus limiting the potential for complaints of incompatibility with airport uses. Furthermore, the Board of Supervisors finds that, because the open space provided by the new PD zoning exceeds that recommended by CalTrans for residential developments within both the Inner Turning Zone and Traffic Pattern Zone, where the Stephens' project is located, safety, as well as noise, overflight and air space protection concerns, are reduced well below CalTrans' recommended thresholds to ensure a.irport compatibility. 6. Based upon the location of the Stephens' project within the Inner Turning Zone and the Traffic Pattern Zone, CalTrans data further demonstrates that the safety hazard risk for all accident sites--- arrivals and departures -- is minimal. Specifically, the CalTrans Handbook "-indicates 'on page, 9-17 that for airports with runways of 6,000 feet or more, --.the chance of all -aircraft accidents within the Inner Turning Zone is 0.03%/acre in Table 9A, "Safety Compatibility Issues." The likelihood of all aircraft accidents within the Traffic Pattern Zone for runways of the same length is 0.02%/acre as indicated in Table 9A in the CalTrans Handbook. Because the likelihood of ain aircraft accident is so low, between 2/100 of 1 % and 3/100 of 1 % anywhere within a full one -acre area, the Board of Supervisors finds that the likelihood of an aircraft accident involving any particular residential dwelling represents an exceptionally low safety risk, well within.the acceptable limits recommended by the CalTrans Handbook. is 7. As described above, on November 18, 1998, ALUC reviewed the Stephens' application for -consistency with the October �1, 1998 purported amendment to the 1 ' 978. CMAEP. The Overflight Protection Zone (OPZ) adopted as part of these amendments seeks to prohibit new single-family residential development. Based solely upon unspecified information allegedly from the Chico.Municipal Airport tower, ALUC's unsubstantiated opinion is that an unquantified number of heavy military aircraft and firefighting air tankers make unscheduled low -altitude approaches, which operations involving these types of aircraft can be particularly annoying to residents because of their size. Based solely upon this statement unsupported by substantial evidence in the administrative record, ALUC-concluded that the only effective strategy is to prohibit residential development because the CalT ' rans Handbook 'recommends that the ideal strategy cited on Page, 3-9 of the handbook 'is to avoid development of Butte County Department of Development Services Agenda Report s K:Schustor HomsXcrlh Chico Subdimsion (6096-0001)�zgenda repon (bos).wpd 13 31&01214 PM residential uses in affected locations. However, page 3-9 of the CalTrans Handbook also states that:. To the extent that this approach is not, practical, the alternative is to make people better aware of the airport's proximity before they move to the area. This can be accomplished through.buyer aw6renes.s­ measures such as: Dedication of aviation or overflight easements, Recorded deed notices; and/or Real estate disclosure statements., Thus, the Board of Supervisors concludes that a complete prohibition of new tingle -family residential dwellings is hot only not practical, -but. clearly not*, necessary. if these three CalTrans-recommended measures are followed. Inthis case, the Stephens Development Agreement minimizes potential incompatibility with the airport by already incorporating all three of these- buyer awareness measures. Because of the inclusion of these several buyer awareness measures in the Development Agreement, the Stephens'. application incorporates other adequate "compatibility 'strategies" recommended by CalTrans to make the project compatible with the'Chico Muni.cipal Airport without the need to avoid, residential development in this location. 8. Regarding whether the Stephens' -project, creates.'a. safety or overflight concern posing any threat to continued -firefighting- air tahker dperations at the Chico Municipal Airport, Gary, F.Ross, Unit'Chief, Butte Ranger Unit, Butte County Fire Department and California Department of Forestry and Fire Protection, states in his May 6, 1998 letter to the Board of Supervisors that: The California Department of Forestry and Fire Protection and the Butte County Fire Department find no potential negative. impact resulting from the proposed amendment to the North Chico Specific Plan which would allow increased residential density on certain portioris of the property owned by Robert and Ann Stephens. The property, identified as APN 047-250-141, is located west of'Hicks Lane in Chico, California. In that the planned development provides for leaving 103 acres along Hicks Lane as open space, adjacent to the Chico Airport, there will be no significant impact on the fire fighting air tanker activities that operate from the airport. Likewise, the increased density from one acre parcels to 3/4 acre parcels on the remainder of the property, as specified in the proposal, will have no significant negative impact on fire fighting resource planning requirementsw Based upon Mr.. Ross'letter and all of the reasons described in Sese findings, the Board of Supervisors hereby concludes that establishment and application o'Butte County Department of Development Services Agenda Report n 14 Mi 2:24 PM KASchuster Hor=ft* Chico SubdiNision (6096-0001)%agenda repod (bos).wpd of the OPZ by ALUC on October 21 and November 18, 1998 along with ALLIC's corresponding policies and measures are unnecessary to protect the public health, safety and welfare, as well as to protect the continued viability of aircraft operations to and from the Chico' Municipal Airport. F ' urthermore, the. Board concludes that because the Stephens' application already includes the. application of.the several significant land use measures described herein which minimize the public's exposure to excessive. safety (and noise) hazards in' compliance with Public Utilities Code Section 21670 and 216.76. B. Noise. 'The Chico Municipal Airport FAR Part 150 Airport Noise Compatibility Program and Env ' irons Plan (FAR Part 150) states on pages 1-5 and 1-8 that the General Plans of Chico ' and Butte County set forth maximum exterior noise 'levels for residential and other noise -sensitive uses to be a Community Noise Equivalent Level (CNEULdn) of 65 decibels (dB). The intent of these standards is to establish guidelines and methods for determining the acceptability of specific land uses with ' respect to various noise levels since these levels usually allow normal outdoor and indoor activities, such as communication and sleep, to occur without interruption. CNEL 65 dB is the criterion noise level above which residential and 'other noise -sensitive land uses (e.g., schools, churches, hospitals and libraries) should not be allowed unless noise attenuating construction is utilized. Table 111-1, "Recommended Land Use Compatibility Designations Chico Municipal Airport" from FAR Part 150, states that residential land uses are compatible in areas .,exposed -.to a.'CNEL of..up..,to* 70 dB, but recommends that measures to achieve outdoor -to -indoor noise*reduction levels (NLR) of at least 25 dB and 30 dB shodId.b*e`incorporated into -building codes and be considered in individual approvals. According to the FAR Part 150 study, the maximum amount of noise to which any portion of the.Stephens' project site is exposed, even projected for the year 2010, is a'CNEL of 60 dB. Approximately 25% of the site lies between the 60 d13 and 55 dB contours. The remaining approximately 75% of the site lies outside of the 55 dB contours as -demonstrated in Exhibit 1-3, "Noise Exposure Map: 2010 Forecast.Conditions," and Exhibit 111-1, "Airport Noise Compatibility Plan." 2. As explained previously, in Exhibit B (Drawing CIC -1 5) to the October 21, 1998 action, ALUC sought to amend the 1978 Chico Municipal Airport Environs Plan (CMAEP) by combining the "CNEL Noise Contours" (Drawing CIC -3) in the 1978 CMAEP with'the CalTrans Safety Zones described above. The noise contours from CIC -3, which were prepared*in 1978, have been shown by much more recent analysis to be an overly optimistic view of future air traffic potential for the Chico Municipal Airport. In an "Aviation Activity Forecast" prepared by P & D Aviation (P & D).as part of the Aircraft Noise Exposure Map Report in 1992, it 'was revealed that the Federal Aviation Admini s*tration's National Plan of Integrated Airport Systems (NPIAS) growth forecast was in excess of 5% per year for Chico airport expansion*. This underlying assumption ?or the noise contours in CIC -3 of the 1978 CMAEP is now "believed to be an a Butte County Department of Development Services Agenda Report a K:SchustefXornesWo*ChiCo Subdivision (6096-Ml)lageidarepon(bos).'mpd 15 YH1.2:24 PM overly -optimistic view of future air traffic potential." (P & D, p. I 11-10.) The result being that,-"[t]he 1978 Environs Plan [CMAEP] forecasts have proven to be highly optimistic." (ibid.) Bated upon more current and more precise data, P &. D also considered an "Enhanced Growth Forecast" for the Chico Municipal Airport to seek to determine a more accurate u . pper range for aircraft activity that more realistically might result from increased aircraft activity at the Chico Municipal Airport. The Enhanced Growth Forecast assumed .'the commencernent of a Flight Training Center at the Chico Municipal Airport by.the year 1995. Flight training operations,were assumed to increase at an average annual rate of 3% per year through the year 2010 forecast p , eriod. . (P. & D" Exhibit 111-1 on p. 9 and pp. 111-12 to 111-14.) At the end of 1998, a flight training facility has not yet been established. "The Enhanced Growth Forecast provides for the introduction'of approximately 5,000 annual operations of turboprop aircraft operations (e.g.,'Beech King Air) by the year 2000.... The Enhanced Growth Forecast also includes allowances for yet additional.flight operations of multi -engine aircraft for several classes of general aviation users.... Allows for, greater.use by heavy turboprop.... For example, expanded aerial firebomber. operations or additional corporate aviation.... The potential for greater levels of corporate turbojet activity is also provided for in the "Enhanced Growth Forecast." (ibid.) The Enhanced Growth scenario resulted in a total of approximately 173,000 total annual aircraft operations in the year 2010 for the Chico Municipal Airport. (P & D, Exhibit 111-2on page 111-16.) The1978CMAEP assumed a total of 250,000 annual aircraft operations in the year 2010. (Ibid.) (This is 77,000 fewer operations or 31% less than the assumptions which created the noise contours in Drawinq CIC -3 of -the CMAEP that were relied upon in Drawing CIC -15 by ALUC on'Octobe-r 21', 1998.) P&D also analyzed. in the same study an '.'Indigenous Demand Forecast" projecting,growth based upon actual annual aircraft operations at the Chico Municipal Airport. The Indigenous Demand Forecast projected a total of approximately 130,000 annual aircraft operations in the year 2010. (Ibid.) (This is 120,000 fewer operations or 52% less than the assumptions which created the noise contours in Drawing CIC -3 which were relied upon in'Drawing CIC -15 by ALLIC on October 21, 1998.) Based upon this expert analysis, P & D concludes that, "[i]t is very important to note that available annual airport capacity greatly exceeds the 20 -year forecast for aircraft operation's under both the 1ndigenous and enhanced growth scenarios." (P&D, p. 111-15.) This means that under either current total aircraft operations, or a more realistic forecast of future growth, total aircraft operations at the Chico Municipal Airport fall far short of the much higher total aircraft operations assumption reflected in the noise contours in Drawing CIC -3 of the 1978 CMAEP which comprise the noise contours now relied upon by ALUC.in Exhibit B (Drawing CIC -14) to the October 21, 1998 ALUC action. It is unclearwhy ALLIC only chose to incorporate portions of the 1995 FAR Part 150 study in its 1998 Safety and Overflight analysis and not to incorporate the updated Noise analysis from the same 1905 study found on Exhibit 1-3, "Noise Exposure Map: 2010 Forecast Conditions" and Exhibit 111-1, "Airport Noise Compatibility Plan." A portion of Exhibit 111-1 was incorporated into ALLIC Exhibit a Butte County Department of Development Services Agenda Report s K:Zchustar HcMeSUM Chico Sub6wsion (6096-0001)kagenda report (bos):*pd' 16 ISO 1 2:24 PM A (Drawing CIC -1 4) and ALUC Exhibit B (Drawing CIC -1 5) in the October 21 ALUC action to establish the Overflight Protection Zone but the noise contours in*Exhibit 111-1, which are based upon the better data described above which are 17 years more current, were ignored by ALUC with no explanation. This aberration is significant and would appear quite. arbitrary since ALUC has stated in writing repeatedly that its position is that the entire .1978 CMAEP. is "terribly outdated." The Board of Supervisors chooses instead to rely upon the much more recent and reliable data found in the 1995 FAR Part 150 program to determine airport noise compatibility, in addition to the 1992 Aviation Activity Forecast for the Chico Municipal Airport by P & D. Both of these more recent studies conclude that, even with future growth scenarios forthe Chico Municipal , Airport, the Stephens'project is, and will likely remain for some time, compatible with, Chico Municipal Airport operations. .3. In ALUC's November 18, 1998 transmittal, ALUC states outside of its "findings" in "Section 3: Other Commission Comments" that the project site is likely to be exposed to single -event noise levels and other episodes which exceed "normally acceptable" noise levels for'residential development. Potential single -event noise level generators are listed as unquantified "intensive" CDF air tanker operations during campaign fires and occasional military activities, Aero Union and other businesses under *contract with CDF and the U. S. Department of Forestry which periodically run up their.aircraft engines at night for the purposes of aircraft engine* maintenance and operational testing. No known or estimated decibel levels were specified by ALUCand no noisestudies are:cited to support this contention. To the contra r)r*, the -,� Board, of,"Sup�ervisors, cites the 1993 CalTrans Handbook at Page 6-27 in its'discussion entitled, "Sleep Disturbance," which states that: A British study (UK Department of Transport --.1992) found that an average person has only a 1 in 75 chance of being awakened by an aircra ' ft noise in the outdoor range of'90 dB to 100 dB SEL. Allowing .for the noise level reduction of the structure, this indicates that indoor single -event sound levels of 70 dB to 80 dB will cause less than a 2% chance of sleep disturbance. Based upon thi's recent British study'and other supporting analysis in Chapter 6 of the CalTrans Handbook, the Board of Supervisors finds that the likelihood of single -event noise, even at extreme 90 dB to 100 dB SEL outdoor ranges to, which people might be exposed during summer months with open windows at nighttime, present no more than minimal public -exposure to noise. 1 4. Based upon the testimony of Robert Koch, an ALUC member representing the City of Chico. and present in ALUC's- public hearings on October 21 and November 18, 1 998, the City of Chico has experienced minimal if any complaints by the'public regarding single -event or any other noise levels generated by the Chico Municipal Airport. Mr. Koch stated on thepublic record that the City of Chico keeps detailed logs of citi.zen complaints and the logs a Butte County Department of Development Services Agenda Report a KASchuster Hornes\Norb) Chico Subdi-ision (60964001)1agenda repon fts).wpd 17 IS101 2.24 PM A r reflect few if any complaints regarding noise of any type generated by the Chico Municipal Airport. In the ALLIC public hearing on November 18, Commission* Member Norman Rosene also stated on the record that it was his belief that no noise study data existed for single -event noise to support ALUC's conclusion that single -e vent noise expos ' ed the public to a hazard of excessive noise. ALUC staff member, Laura Webster, stated, too, that she was unaware of whether CalTrans or any other expert in the field had established specific standards for determining when single -event noise exposure to the public was excessive. 5. ALUC relies upon Exhibit 44, "Land Use Compatibility for Community Noise Environments" found on page 4-33 of the'1978 CMAEP for the premise that noise levels for residential land uses are "normally acceptable" up to CNEL.60 dB. However, Exhibit 4-4 also states that exposure of residential land uses to CNEL up to 70 dB is'also acceptable' if new construction or development is' conditioned to require noise reduction and noise insulation features in housing design. Exhibit 4-4 also states that, "[c]onventional construction, but with closed windows and fresh air supply systems or air conditioning will normally suffice" by itself to keep noise levels in the acceptable range -- even without noise reduction and noise insulation features included in design and construction. Because the Stephens' Development Agreement already requires that "[r]esidential dwelling_units shall be designed and constructed to achieve an interior noise level of no.more.than 45 dB,�'the Board of,Supervisors concludes that community noise'environments.for.resid6ntial,dwellidgs on the Stephens' project, including single-�event noise levels, will remain within acceptable levels under not only the 1978 CMAEP, but also according to the specifications in the FAR Part 150 program and the CalTrans Handbook. C. Airspace Protection. The November 18 ALUC "Project Consistency Findings" state that Chapter 3 of the CalTrah s Handbook identifies fourfunctional categories that address airport land use compatibility concerns. These include: Noise, Safety, Airspace Protection and Overflight ' Protection. While ALUC only found the applicant's proposal to be inconsistent with the 1998 amendments to the 1�978 CMAEP based uponimeasures and policies designed to address Overflight Protection and Safety, the Board of Supervisors also hereby finds that the Stephens' project is compatible with Chico Municipal Airport operations because it does not cause a significant risk to the Airspace Protection. In determining a project's compatibility with Airspace Protection, the.CalTrans Handbook states on pages 3-7 and 3-8 that the particular hazards of concern are "airspace obstructions" and land -use characteristics which pose "other potential hazards to flight. by attracting birds or creating visual or electronic interference with air navigation." "Compatibility Strategies" recommended by CalTrans for protection of airport airspace are, (1) to avoid airspace obstructions by limiting the heigqt of buildings and antennas'and other types of structures and trees so as not to pose a potential hazard to flight and (2) land uses which may create the types of a Butte County Department of Development Services Agenda Report w K:'Schuster Homes%NcM Ctico Subdmsion (6096-0001)%agenda repw (bos).wpd . 18. MI 124 PM 0 A E. Ibed above should be avoided near. an airport or modified so as hazards descr not to include the- offending characteristic (i.e., attractions to birds, creation of visual or electronic inte'rference with air navigation). The Stephens' project proposes single-family residential dwellings and related.,. land uses which, by their nature, and by existing.design standards,. are generally limited to heights below 35 feet and. are otherwise designed so. as not to pose a potential airspace obstruction. Furthermore, no evidence has been presented by ALUC or'otherwise on the record to demonstrate that land uses associated...,.' with the project create potential hazards to flight by attracting birds *or creating visual or electronic interference with'air navigation. These'types of hazards are not hazards which would normally be expected as a component of a standard single-family residential development of this type on the Stephens' property. Conclusion to airport consistency find Based upon all of the substantial factual evidence . submitted into the record during the course of the several public hearings upon the Stephens' application before ALUC, the Butte County Planning Commission, and the -Butte County Board of Supervisors in 1997 and 1998 as described in these findings and the exhibits and attachments and other data referenced herein, including the Applicant's Exhibits in the Administrative Record dated June 23,''1968, all of which are incorporated herein into the administrative record by reference, the Board of Supervisors hereby concludes in. fulfillment of the requirements of Public.Utilities Cod'e-Sections 21670 and 21676 that approval of the St ' ephens' project provides for the,orderly development.of the Chico .Municipal Airport and the area surrouhding!the airport so as to promote the overall goals and objectives of the California Airport Noise Standards -adopted pursuant to Section,21669 of the Public Utilities Code, and, as designed and conditioned, the Stephens' project prevents the ' creation of new noise and safety problems. Furthermore, as designed and conditioned, approval of the Ste ph ens' project protects .the public health, safety and welfare -by ensuring the orderly expansion of the Chico Municipal Airport by'and through the adoption -of the numerous land use measures described herein. and in the exhibits attached hereto which rhinimize the- public's exposure to excessive noise and safety hazards within a.reas around the Chico Municipal Airport, and which also.adequately provides for overflight and airspace protection.'

Proposed Specific Plan Improvements The overall circulation concept for the North Chico Specific Plan (NQSP) area.is development -- of a circulation pattern which provides adequate levels of service, a reasonable and conv6ni6n't'- access pattern, and recognizes and corrects existing and potential access problems..... The circulation system for the Plan area was developed based on results of the traffica�a�is prepared for the Specific Plan which evaluated project traffic generation, road and intersection.. operations under existing and buildout conditions. Traffic was distributed on vicinity roads based on utilization of the Chico Area transportation model developed by the City of Chico. In developin- the circulation system for the Specific Plan, Level of Service "C" was assumed io be the minimum acceptable standard. It was also assumed that no new traffic signals would be installed alon- State Route 99 (per Caltrans policy), that existing lane configurations would be used as the basis for all scenarios, and that Eaton Road would be extended to State Route 32 and easterly to Manzanita to form a ring road around the urban area. In order to provide an adequate circulation system through the Plan eenumber of road and T 1 9-6.

L__ CV e I TO 5� Existing intersections will require s e modifications, especially along Eaton Road where signals will be required at the intersections with the State Route 99 interchange, the New Arterial, and Cohasset Road. Due to the proximity of Hicks Lane to the Eaton/State ' Route 99 intersection, the Plan requires traffic control on Hicks Lane to right -turns in and out, only. Within the NCSP area, multi -way stop signs will be necessary at the intersections of the new road with realigned Hicks and Garner.- -A stop sign also will be needed on the New Arterial at its intersection with State Route 99. The Plan also provides for the safe and efficient movement of vehic'les, bicyclists, pedestrians, and equestrians. A network of bicycle paths and pedestrian trails link the North Chico Specific Plan area with surrounding areas within the Chico community. LMPACTS AND MITIGATION MEASURES Standards of Significance: For the purposes of traffic and circulation impacts, the criteria for determining significance include creation of or contribution to unacceptable leveli of service; inadequate road width; an&or creation of inadequate circulation patterns. Impact: Implementatio * n of the Specific Plan will result in an increase of approximately 63,000 daily trips and approximately 7,000 PNI peak hour trips.

Westbound left turns from Keefer onto 99 will continue to operate at Level Service "E." The feasibility of potential improvements to this intersection is limited-dy.e.'.0 Caltrans' policy which would discourage si analization at this location. - The only mitigation to reduce the level of service to a "less -than -significant" level would be the construction of.a"full interchange. Therefore, traffic at this'intersection will exceed acceptable'servic6-,1eV6,1§,' resultifig, in a significant, unavoidable impact, although overall traffic volumes will remain relatively low at this location (262 total peak -hour trips with project compared to 174 existing trips, with total left -turn movements increasing by 20 peak -hour trips). The traffic identified for buildout of the NCSP area represents a worst-case condition and doe's not take into account two key components of the Plan: inclusion of shopping and employmen ' t centers within the Plan area, and incorporation of bicycle and pedestrian tails to fa�ilf - t - e alternative modes of transportation within the Plan area. Key components of the Plan aire. integration of land uses which minimize commute traffic and a system of trails to encourage pedestrian and bicycle travel. The mixed-use desi an of the Plan, combining residential, commercial, industrial, and grade school in close proximity, allows for greatly increased pedestrian and bicycle trips in place of automobile trips. To achieve a reduction in auto trips, the Plan emphasizes the separation of vehicular traffic from other modes of ' transportation, making, non -auto trips short and pleasant. These features of the NCSP could reduce project trips by 5% to 10%. Project Elements that Mitigate.

Addition of Specific Plan traffic to cumulative traffic would further decrease the level of. service at the State Route 99/Garner Lane intersection, necessitating the addition of a southbound lane on Garner. Cumulative traffic increases would also further worsen cumulative conditions at the Eaton/State Route 991Hicks intersection and the Eaton/Cohasset intersection.

Airport operations raise issues of safety, noise, and thus land use compatibility issues -for larid uses adjacent to the facility. Noise issues are discussed in the Noise section of, this EIR.,,_ Althouah none of the Plan area is within airport clear zone, the area is withiq general flight pattern areas, which raises concerns regarding safety. Currently, land uses in the Plifiliriii adjacent to the Airport are undeveloped, open space lands, which appear to be mostly subjecte'd to noise, rather than safety issues. The areas immediately adjacent to the Airport are generally designated for low-density residential or light industrial uses, which typically would not result in significant concentrations of people. The proximity of the airport to the area also raises safety issues associated with siting of a new elementary school as proposed in the Plan. During the course of preparation of the NCSP, the Chico Unified School District (CUSD) Site Acquisition Steering Committee evaluated five potential elementary school sites in the NCSP area. These sites were evaluated against the District's siting crit ' eria, and reviewed by the -U—.S-. California Department of Transportation, Division of Aeronautics due to their close proximity to the Chico Municipal Airport. The Aeronautics Division detem-dried that of the five proposed sites, the sites along Keefer Road and Hicks Lane were unsuitable for school sites because of safety and noise issues related to frequent overflights at 400 to 800 feet above ground level.

LAND USE Existin2 Land Uses The North Chico Specific Plan (NCSP) area is located north of and adjacent'to the bulk o'f'tfi6,,,r Chico urban area. The Plan area is genierally bounded by Sycamore Creek,on' 'the south, St- ate Route 99 on the west, Rock Creek on the north "and. Chico Municipal Airport anddear ion'e-o' n-" the east. An an -n of the NCSP boundary extends northwesterly: between Keefer Road'a"nid" Rock Creek. Two smaller portions of the Plan area, consistin of approximate'ly. 1'70 Acres,'air-e located south of Sycamore,Creek to the north of Eaton Road. As more fully discussed in section 3 Project Description, the Plan area is partially devel6ped' with suburban and rural residential, oene'ral commercial and industrial land uses. Approximately 630 dwelling units and 1,450 residents now reside within the area, with:Ian additional 70-80 dwelling units immediately adjacent. Lot size is variable, ranging from I to�'5� acres in the area adjacent to Keefer Road to smaller, more suburban-8ized lots (.5± a6r�s) in*th�'�.' subdivisions eas ' t of State Route 99. The residential area along Keefer Road appears wl*ell established, with little potential for change, except for some limited infill. Figure 3-2 provides a graphic summary of developed and undeveloped lands within the NCSP area. The undeveloped parcels within the Plan area total. approximately 2,100 acres and are comprised mostly of fallow land, with roughly 500 acres of almond, walnut and olive orchards. The orchard uses are generally in th"e westerly portion of the Plan area, where soils are deeper. The majority of soils in the NCSP are classified as Class VII according to the Soil Conservation Survey. Under these *classifications, Class I or Class 11 soils are con sidered prime agricultural coils. There are limited areas of Class I soils adjace.nt-to State Route 99. Other vacant parcels have been used for seasonal livesiockgrazing, A forTner quarry is located in the central portion of the area, north of Mud Creek and east of C' Garner Lane. Recional land uses are generally far less ext C� ensively developed, with heavy agricultural uses westerly of State Route 99 (Skg9*), and open space/seasonal grazing to the'l-north between SR99 and the foothills. The Chico Municipal Airport and clear zones predominate the easterly edge of the Plan area, along with a former missile base (now abandoned), and rural residential uses. Chico Municipal �iMorT Operations The Chico Municipal Airport contains two parallel runways that are used by air carriers, air taxi, and -eneral aviation operations. Runway 13L/I'R 6,722 feet long and is used by air carriers and other heavy aircraft, as well as a majo ity of the creneral aviation operations. ri Runway. I ' )R/3 I L is 3,004 feet lon(Y and is used for liolht aeneral aviation aircraft operations. I -; I Land Use Local flight patterns operate both east and west of the airport, but foothills located easterly of the airport limit pattern operations in that direction. Approximately 150 permanently -based aircraft were housed at the facility in 1992'. Ile number of annual airport operations has fluctuated between 58,000 and 9 1,000 over the last 14 years. Operations in 1992 totaled 74,642. It is projected that total operations will incre'w.to 173,000 by the year .20 10 (McClintock, Becker & Associates, December'l 092) In evaluating potential conflicts arising between the airport and other land uses, three issues must be addressed: safety, flight hazards and noise. Airport noise issues are addressed in. section I I of this draft EIR. Areas near airports are' exposed to various levels 6f accident' potential depending *on the type of aircraft using the airport, the frequency of aircraft overflights, and local weather conditions. Historically the risk of being killed or injured on the ground near an airport is extremely small. Various reasons have been offered for the-low-.-� incidence of major accidents near airports in relation to the volume of traffic handled. These include the safety features designed into modem general aviation and commercial aircraft, pilot actions in accident situations, and preventive land use planning. (Metropolitan Transportation Commission, 1983). Enaine failure or malfunction is the most frequent type of general aviation accident. Eng"ine',.'. failures are most common during climbout when the engine is exerting maximum power. No all engine failures result in crashes, since the pilot may be able to make a controlled landing at_.:',. the airport or in a clear area around the airport. Control problems are more difficult in twin engine aircraft if an engine fails. The principal types of accidents occurring during landin'gs are short landing, stalling the aircraft (due to lack of air speed), running out of fuel, failure to"clear obstructions in the approach path, and engine failure (ibid.). A variety of safety zones are established around airports to minimize impacts of an accident. Clear zones/safety zones are established in order to provide for land use controls around airports. The purpose for establishing land use restrictions in safety zones is to minimize the number of people exposed to aircraft crash hazards. The two principal methods for reducing the risk of injury and property damage on the ground are to limit the number or concentration of persons in an area and to limit the area covered by structures occupied by people. The FAA clear zone and imaginary approach surfaces that extend outward from an airport's 4= runways along the extended runway centerline have commonly been used to establish airport Im safety zones. Clear zones are fan -shaped (trapezoidal) areas nearest to the runway that must be kept clear of major structures or concentrations of people. These areas lie on the ground underneath the imaginary runway approach surfaces described below. Safety concerns are areatest in the clea�zone areas due to the possibility of crashes on takeoff or landing. The dimensions of runway clear zones vary according to ihe type of aircraft that utilize the airport and the operating capability of the airport during poor weather (Ibid.). C C The Chico Municipal Airport Environs Plan (1978), evaluates noise exposures and safety considerations regarding airport operations, and recommends guidelines for development in the 0 airport environs. "Compatible Land Use Zone" (CLUZ) planning areas are established in the C Airport Plan and were developed by superimposing the noise contours, au'craft flight corridors, and land ownership boundaries. The plan recommends where and what type of nolse control Land Uie I ;.-) -�x 0 Draft -Environnsemat Impacf Norfh i6 SpeciJ measures and land use intensity" m—ay 'be, necessary to achieve consistency with airport operations.

LMPACT� AND MITIGATION MEASURES Standards of Significance: Future development would be considered to..-resule. in significant impacts if land use patterns or character of the surrounding area are substantially altered, planned land uses result in incompatible uses adjacent, or land use intensities are. incompatible.with airport operations. The majority of the Plan area is undeveloped, but the existing residential subdivisionsalong Keefer Road and east of State Route 99 establish a development pattern for these portions of the Plan area. The combination of ±1 -acre residential lots and surrounding open space also creates a rural character for the area. The proposed I- to 3 -acre lots'nor-th of Mud Creek are consistent with lot patterns established in this area. The planned Mud Creek greenbelt also will serve to buffer existing and planned lower density residential land uses north of the creek from planned highu density uses in the Village Core, south of the Creek. However, an area -of medium density residential (6-8 units/acre) is planned north and west of the existing 1 -acre' lot subdivision off of Caballo Way. This does not allow for adequate buffer between existing suburban I -acre densities and the higher urban densities of the Village Core. Impact: Conversion of approximately 1,630 acres of existing open space to urban/suburban uses. This is considered -a significant, unavoidable impact. Implementation of the Specific Plan will cause the developrhent of a majority of the existin- a open space/vacant lands within the plan area to urban and suburban uses. This is significant because the acreaoe involved is substantial and the conversion is irreversible.

Airport operations raise issues of safety, noise, and thus land use compatibility'issues for land . y uses adjacent to the facility. Noise issues are discussed in the Noise section of this EIR.

The proximity of the airport to the area also raises safety issues associated wi ' th siting o f anew elementary school as proposed in the plan. During the course of preparation of the NCSP, the c' Chico Unified School District (CUSD) Site Acquisition Steering Committee evaluated five potential elerfientary school sites in the NCSP area. These sites were evaluated against the District's siting criteria, and reviewed by the U.S. Department of Transportation, Division of Aeronautics due to their close proximity to the Chico Municipal Airport. The Aeronautic.s Division determined that of the five proposed sites, the sites alon,, Keefer Road and Hicks Lane were unsuitable for school sites because of safety and noise issues related to frequent overflights at 400 to 800 feet above ground level. The school site identified in the North Chico Specific Plan was approved by the CUSD, and the U.S. Dept. of Transportation, Division of Aeronautics. As the area develops, and the residential population increases, there may be increased complaints regarding airport operations or noise. The development regulations set forth in the Specific Plan require dedication of avigation easements as part of new development. Generally, an avigation easement is intended to protect certain airport rights, such -as right-of- fli-ht at an altitude above acquired easement surfaces, right to cause noise, vibration, fumes, ve dust and fuel particle emissions, right to prevent erection or growth of all objects abo acquired easement surfaces; and the right to prohibit creation of electrical interference, unusual C light sources and other hazards to aircraft flight. Recognizing that many complaints regarding conflicting land uses arise from the perceived failure of disclosure as to the potentially offensive use, the Specific Plan requires several measures meant to ensure proper notice.

The proposed NCSP generally is consistent with existing Butte County 'General Plan' desiomations, except for the Village Core. In this area a combination of commercial, . office aid urban -density residential uses are.proposed. A review of project consistency with existing County policies is provided in Appendix A of the Specific Plan. The analysis does not reveal any inconsistencies. The existing Butte County General Plan Land Use Map also designates a "Greenline" on the Land Use Map to define the limits of urban/suburban development, and separate these uses from agricultural uses. This line generally borders State Route 99 in the project vicinity. According to County policy, the "agricultural side" of the greenline includes lands to the west of the line, which generally includes the area west of State Route 99. Lands to the edst of the greenline. including the Plan area, are considered the "urban side" of the greenline. All uses on the agricultural side of the gre-enline are intended to remain a--ncultural. Citv of Chico Plans As pre,;1ously indicated. the NCSP area is.located on the northern boundary of the Chico Urban Area as s:,.,-nerally defined by the City's Sphere of Influence (SOI).

The parcels range in size from 1.0 to 1.3 acres. The�property is located on the east side of Garner Lane, immediately north of Keefer Slough, northwest of the Chico Municipal Airport. FOR: Airport Land UseCommission Meeting of September 20, 2000 SUMMARY: Staff recommends ALVCfind the project inconsistent with the 1978 Chico Municipal Airport CL UP as amended on October 21, 1998, and December 29, 1999. 1 BACKGROUND: The project site is located northwest of the airport on the east side of Garner Lane, immediately north of Keefer Slough. The property is in the County's jurisdiction and is within the North Chico Specific Plan. The applicant previously submitted a Tentative Subdivision Map for this site proposing 34 lots. On May 18, 2000, ALUC found that project inconsistent with the 1978 Chico Municipal Airport CLUP as amended on October 21, 1998, and December 29, 1999. ANALYSIS: The northwest comer of the project site is designated on the North Chico Specific Plan as the location for a 5 -acre neighborhood park. The proposed park location contains the best soils on the property for sewage disposal. As a result, the applicant is proposing to relocate the park site to the southerly portion of the site, adjacent to Keefer Slough. This requires an amendment of the NCSP to change the General Plan for the old park site from Public to Agricultural Residential and from Agricultural Residential and Open Space to Public for the new park site. Corresponding rezoning to PQ and SR- I will also be implemented. The NCSP currently requires a I 00 -foot riparian buffer and a I 0 -foot bike path easement along the north side of Keefer Slough. The change* will replace the open space land with a neighborhood park for this stretch of Keefer'Slough. Along with the proposed general plan and zoning changes, the applicant has submitted a revised Tentative Subdivision Map to create 30 parcels ranging in size from 1.0 to 1.3 acres. The proposed design utilizes a single loaded street adjacent to the park land, consistent with the design standards in the-NCSP. The resulting average density is one dwelling unit per 1.5 acres. * Butte County *Airport Land Use Commission # ml oi 0 I 0 0 According to the 1999 Chico Airport Land Use Plan amendment, Safety Zone Map "6- 1," the project site is partially located in, Overflight Protection Zone A/Overflight Protection Zone B and totally situated within Safety Zone 6 -Traffic Pattern Zone (refer to Exhibit Q. Overflight, Zone A prohibits new residential uses. Overflight Protection Zone B prohibits new single family residential uses but allows multi -family residential development. Safety Zone 6 allows residential development at a density not to exceed one dwelling unit per 2.5 acres. As proposed, Lot 1.8 and half of lot 1.7 in Overflight Protection Zone A and cannot be developed with any type of r esidential uses. The majority of lots 19, 20, 29, and 30, as well as half of lot I are in Overflight Protection Zone B, where the development of new single family dwellings is prohibited. The remainder of the property, approximately 28 acres, may be developed with a 2.5 acre minimum parcel size. The current project proposes an average density of one dwelling unit per 1.5 acres. Taking into account all of the CLUP provisions, the development potential for the site is approximately I I parcels of 2.5 acres or larger. All lots must be located in Traffic Pattern Zone 6. Development in this zone is subject to other criteria that are not applicable to the proposed project for single family residential uses. The proposed changes to the General Plan and Zoning are more compatible with airport operations than the existing plan layout. By moving the park area adjacent to Keefer Slough, more non- residential acreage is placed in the more restrictiVe Overflight Prbtedction Zones A and B. However, the SR- I zoning must stillbe found inconsistent with the density recommended by the ALUC. The proposed changes do have one positive feature, potential useable open space for emergency landings. " The combined park, roadway, and drainage detention basin provide an area approximately 250 feet wide -and 1,400 feet long. With consideration given to where trees are planted, this could be one of the "bail out" sites the Commission desires. The applicant has expressed a willingness to deed this land to the County or Chico Area Recreation District if the project were approved for the number of lots proposed. Flight Tracks: The subject property is located directly under the generalized flight track for light aircraft. According to available maps, it, is also under the location where planes are turning to make a landing. As discussed at the July 19, 2000, ALUC meeting, this is a point where pilots are having to make adjustments to their aircraft to prepare for landing. The general consensus of the Commission was that densities should be limited in these areas. I I Consistency with the draft 2000 CLUP: Since the Commission appears to have reached some consensus on the Draft 2000 CLUP, staff has included an analysis for a consistency finding relative to the prov isions of this Draft. At this time, only a preliminary review is possible, along with the understanding that the proposed planisin a state of flux and may still change. At the July 19, 2000, ALUC meeting, it was the consensus of the Conunission to designate this area as a compatibility zone C 1. The C I compatibility zone limits the N *Butte County *Airport Land Use Commission 2 0 , 0 residential density, to not more than one dwelling unit per five acres. Based upon the recommendation, this project would not be compatible with the proposed 2000 CLUP criteria. Airspace Protection and Safet The topography of the site is ' generally level. The site elevation is approximately 200 feet above sea level. The project site is located under the horizontal surface which has an elevation of 388 feet above sea level. With approximately 188 feet between the ground and horizontal surface, and a 35 - foot maximum building height imposed by the zoning, no conflicts are expected. The execution of an avigation easement is recommended to protect future airport operations. The 1978 CLUP for the Chico Municipal Airport, as amended on October 21, 1998, contains diagrams which depict the locations of potential aircraft -related accidents for the facility based on general accident scatter information presented within the 1993 Airport Land Use Planning Handbook (refer to Exhibit D - CIC -17). The highest concentration of both departure- and arrival -related aircraft accidents takes place within the Runway Protection Zone and Approach Surface. Due to the project site's location ' in an overflight zone, approximately 6,000 feet away from the northerly end of runway 13L, the risk of aircraft -related accidents is not considered significant for the residential density recommended in the CLUP. Environmental Documentatio No environmental documentation has yet been prepared for this project. RECOMAHNDATION: Staff recommends that the Butte County Airport Land Use Commission find that ALUC File No. AOO-07, General Plan Amendment/Rezone and Revised Tentative Subdivision Map (APN 047-350-013, 014, and 015) is inconsistent with the 1978 Comprehensive Land Use Plan (CLUP) for the Chico Municipal Airport, as amended on October 21, 1998, and December 29, 1999. If a residential subdivision is to go forward on this property, it is recommended that the project be re -designed in accordance with the conditions listed in Exhibit "A".

These data are based on the findings of a number of studies, documents, and reports generate& by individuals, firms, and agencies recognized as having expertise in the field of Airport Land Use Planning and land use compatibility (refer to Exhibit B, List of References). The following findings have been prepared at the direction of the ALUC and are for the consideration of the Lead Agency (County of Butte) when *making a decision on the project. SECTION 1: ENVIRONMENTAL FINDINGS A. No environmental documentation was submitted at the time of project review. SECTION 2: CONSISTENCY FINDINGS FOR PROPOSED PROJECT A. The proposed project is inconsistent with the 1978 Comprehensive Land Use Plan (CLUP) for the Chico Municipal Airport, as amended on October 21, 1998, and December 29, 1999, as follows: I A portion of the proposed project is located in Overflight Protection Zone A. This, area is subject to frequent low altitude overflight activity. No new residential uses are permitted within this zone. The proposed project shows one parcel and the majority of two other parcels, planned for single-family residential use, in this zone. 2. A portion of the proposed project is located in Overflight Protection Zone B. This area is subject to less intensive overflight activity. No new single-family development is allowed, but multi -family uses may be permitted in this zone. The proposed project shows three par cels' and the majority of four other parcels, planned for single-family residential use, in this zone. 3. The balance of the proposed development is in Safety Zone 6 (Traffic Pattern Zone). This area permits residential development at a density not to . exceed I dwelling unit per 2.5 -acres. Inconsistent with that, the proposed project shows residential lots ranging from 1.0 to 1.3 acres in size within this zone. I Butte County *Airport Land Use Commission 4 0 B. Approval, of the project as proposed would necessitate the -adoption of Overriding Findings by a 2/3 vote of the governing body. Overriding Findings by the governing body can only be made based on substantiated facts and must be supported by new substantial factual evidence introduced into the public record that the proposed action is consistent with the State Aeronautics Act. as stated in Section 21670. Overriding Findings cannot be adopted as matters of opinion, heresay, or upon the unsubstantiated fears and desires of the governing body. SECTION 3: PROJECT REQUIREMENTS FOR CONSISTENCY If the applicant wishes to revise the development proposal to conform with the requirements of the 1978 Comprehensive Land Use Plan (CLUP) for the Chico Municipal Airport, as amended on October 21, 1998, and December 29, 1999, the following conditions shall apply: The lot design shall be amended to show no single family residential building sites within either Overflight Protection Zone A or B. No residential lot for a single family dwelling shall be less than 2.5 acres in gross size. 2. A condition shall be required on the Final Map stating that prior to the issuance of a Building Permit the property owner shall sign an avigation easement granting to the City of Chico the right of continued use of the Chico Municipal Airport in the airspace above the proposed parcels and acknowledging any and all existing or potential airport operational impacts. SECTION 4: ADDITIONAL FINDINGS A. Airspace Protection The Conunission finds that due to the topography of the project, there are no transitional surface problems. The subject property is located slightly below the airport surface with approximately 188 feet between the ground level and the horizontal surface. Approach surfaces would not be affected due to topography or ftiture development. A condition should be included on the Final Map stating, that any project -related lighting shall be directed within the project site and shielded to prevent adverse impacts on adjacent properties and aircraft flight activities. #Butte County *Airport Land Use Commission # 5 2. A condition should be included as part of the proposed rezone or future parcel map stating that uses which have the potential to create visual, electronic, or physical flight hazards including the generation of dust, smoke, glare, electronic interference, or the attraction of birds, to the p rioject area shaU be avoided. Accident scatter information adopted as part of the October 21, 1998, Chico Munic*ipal'Airport CLUP Amendme ' nt, Exhibit D (Hodges and Shutt -1993. and UC- Berkeley, Institute, of Transportation Studies - 1993) indicates that the highest' concentration of both departure- and arrival -related aircraft accidents� takes place within the Runway Protection Zone and Approach Surface off the ends of the runway and on either side of the runway. Due to the project site's location away from these runway areas, no special conditions ate necessary for safety -purposes provided that the recommended residential density is adhered �.to.
