(a) Page IV -3 The statement "The analysis shows, however, that most of the significant noise problems are within the incorporated areas of the County" is questionable since 35% of the County's population live in the unincorporated areas of Chico and Paradise, (b) Page IV -9 The natation "Inside incorporated boundaries„ used in the "Roadway Type's ,far Highway 99, Skyway interchange to the Cohasset Highway interchange, should be changed to "High Saeed"; This would allow assessment of potential freeway/ noise for the ,inincorPorated lands found adjacent to the alcove referenced 100 gray.

The City will be including the 50dhr contour in a future arr~endment to its General Plan. i) Page IV -20 The noise contours for the Chico Municipal Airport do not include 600; or snow longi -range trends as required by State mandate. Present contours wore a TO: 2 Butte County Planning Commission RE Proposed Elements -to the Butte County General Plan projected based on previous Air West flight schedules (all flights before 10:00 P.M.) and do not take into consideration the air tanker operations during fire season. (e) Pago IV -21 Noise -Sensitive Areas. School sites within the. City, but adjacent to County unincorporated areas, must be identified as noise sensitive areas (per Government Code) and consequently should be monitored to determine noise exposure levels. Such sites should also be included on Map IV -1 (f) Page IV -25. Section 65302(8) of the Government Code requires the Noise Element to be considered when developing a Land Use Element which will achieve "noise compatible land use"., Thus, one of the policies should be to revise the Land Use Element in accordance with the findings and policies of the Noise Element. (g) Map IV -1 1. The Continental Nut processing and shipping plant located on the Esplanadu should be shown on the map as an "industri'al noise area". i 2. Current noise contours and long range predictions should be provided for all areas identified as "Noise Areas" on the map, (h) The Commission regretted to see that Section 2.2 (Noise -Compatible Land Use Planning) in the Preliminary Draft Noise Element, was not included within the present draft: Said section is very informative to the reader and an excellent p d recommendations of the citizen theNoeuse in seElemeni�n'lunctian with the policies an II Draft Seismic Safety Element It is recommended this element call for more specific and refined soils data to determine probability of iiquification potential and other geologic problems related tol seismic safety.: III Safety Element It is recommended this element should provide a specific evacuation route plan.

March 4, 1977 j As requested by the Board, the County Planning Commission herd a special meeting Thursday evening, March 3, 1977, to review all element changes proposed by Board members and others. The results of that review are summarized herein. Six Commissioners were present, as well as 10 to 15 people in the audience, including Supervisor Moseley. Commissioners expressed concern about the lack of time to review proposals and the number of proposals to consider. After comparison of different versions of findings, policies and implementations the 'Commi sion recommended their preferred wording. Majority approval of each statement was indicated informally by voice, formal motions were passed approving revisions for each element. Many proposed wording changes mere accepted by the Commission; while others were rejected in 'favor of the Commissio.n's orijinal recommendations to the Board. The various text changes proposed were referred back to staff and the Board for their consideration. B. B G BG: db enclosure tIQARq Q sUhl 9V1—OLS 1.
