HomeMy WebLinkAbout117-AB 162 Compliance Review.pdf Attachment 4 AB 162 Compliance Review Assembly Bill 162 was passed by the legislature and signed by the Governor in 2007. The bill requires cities and counties to review the Conservation and Safety Elements of their General Plans in connection with required updates to the Housing Element. The Conservation and Safety Element reviews are required to consider the extent to which those elements address the flooding and hydrology issues described in the first column of the table below. The second column of this table describes how the City of Saratoga’s existing Conservation Element and Safety Element address the issues of concern. For issues not addressed by the current General Plan the third column proposes amendments that would address the requirements of AB 162. Where no amendments are required the third column states “None Necessary.” (In describing changes to existing text, text to be added is indicated in bold double- underlined font (e.g., bold double-underlined) and text to be deleted is indicated in strikeout (e.g. strikeout ). Text in standard font remains unchanged. ) AB 162 Requirement Existing General Plan Provisions Proposed Amendments (if necessary) Conservation Element (CE) Requirement: Identify rivers, creeks, streams, flood corridors, riparian habitats, and land that may accommodate floodwater for purposes of groundwater recharge and stormwater management. CE pg. 4: discussion of flood easements by SCVWD. CE pg. 12: discussion of flood plain. CE pg. 15: discussion of watershed protection areas. Exhibit OSC-3: Identifies areas within the 100- year flood plain. Goal OSC 9: Goal and subsequent policies address protecting existing watercourses and to retain surface water to the greatest extent possible. On page 12 of the Conservation Element, insert the following paragraph at the end of the section titled “Flood Plain & Flood Protection” : As indicated by Exhibit OSC-5, upland areas in Saratoga contribute to groundwater recharge and are protected as watershed protection areas. Given the nature of Saratoga’s topography and hydrology, however, there is no significant accumulation of flood water and consequently, no opportunity for groundwater recharge in association with flooding. Safety Element (SE) Requirements: (A) Identify information regarding flood hazards, including, but not limited to, the following Discussed below. Discussed below. 2 AB 162 Requirement Existing General Plan Provisions Proposed Amendments (if necessary) (i) Flood hazard zones. As used in this subdivision, "flood hazard zone" means an area subject to flooding that is delineated as either a special hazard area or an area of moderate or minimal hazard on an official flood insurance rate map issued by the Federal Emergency Management Agency. The identification of a flood hazard zone does not imply that areas outside the flood hazard zones or uses permitted within flood hazard zones will be free from flooding or flood damage. FEMA maps show the 100 year floodplain. FEMA has not identified any areas of “moderate or minimal hazard.” The SE includes a schematic map showing areas subject to flooding. Other elements of the General Plan include a more detailed map showing the 100 year flood plain. On page 13 of the Safety Element, revise the first sentence of the section titled “Identification of Areas Subject to Flooding” as follows: “Several creek areas in Saratoga have been identified as flood hazard areas (see Map 3, Exhibit OSC-3, Federal Emergency Management Agency maps on file with the Department of Public Works and, with respect to risks from the Lake Ranch Reservoir, the Dam Failure Inundation Hazard Map for Saratoga prepared by the Association of Bay Area Governments on file with the Department of Public Works). Lands within the 200 year floodplain are shown on maps prepared by the Department of Water Resources as part of its Awareness Floodplain Mapping Program available at: http://www.water.ca.gov/floodmgmt/lrafmo/fmb/fes/awarenes s_floodplain_maps/.” (ii) National Flood Insurance Program maps published by FEMA. The City received new Flood Insurance Rate Maps from FEMA, as published on May 18, 2009. These should be referenced in the Safety Element. See text change proposed above. (iii) Information about flood hazards that is available from the United States Army Corps of Engineers. The Army Corps of Engineers declined requests to provide any information in this regard. None Necessary (iv) Designated floodway maps that are available from the Central Valley Flood Protection Board. Not Applicable, as the Central Valley Flood Protection Board pertains to jurisdictions located within the San Joaquin Drainage District, which is located in Madera, Fresno, Merced, Stanislaus, San Joaquin, Contra Costa, Sacramento, Solano, Yolo, Sutter, Yuba, Placer, Colusa, Butte and Glenn counties. None Necessary (v) Dam failure inundation maps prepared pursuant to Section 8589.5 that are available from the Office of Emergency Services. The Safety Element discusses the possibility of failure of Lake Ranch reservoir dams but does not include any mapping. See text change proposed above. (vi) Awareness Floodplain Mapping Program maps and 200-year flood plain maps that are or 200-year flood plain maps are not available on the DWR website. The Awareness Floodplain See text change proposed above. 3 AB 162 Requirement Existing General Plan Provisions Proposed Amendments (if necessary) may be available from, or accepted by, the Department of Water Resources. Mapping Program maps are not referenced in the Safety Element. (vii) Maps of levee protection zones. As there are no levees in Saratoga, there are no levee protection zones. None Necessary (viii) Areas subject to inundation in the event of the failure of project or nonproject levees or floodwalls. As there are no levees or floodwalls in Saratoga, no areas are subject to inundation. None Necessary (ix) Historical data on flooding, including locally prepared maps of areas that are subject to flooding, areas that are vulnerable to flooding after wildfires, and sites that have been repeatedly damaged by flooding. SE pg. 12: section on Historic Data on Flooding in Area. SE pg. 15: information on areas likely to be flooded. None Necessary (x) Existing and planned development in flood hazard zones, including structures, roads, utilities, and essential public facilities. Saratoga does not have homes or essential public facilities planned within any flood hazard zones. In light of limitations on new construction in flood hazard areas there is little development in flood hazard zones. On page 14, immediately preceding the section titled “Flood Control and Emergency Services” insert the following new paragraph: Saratoga works to limit the placement of development in flood hazard areas through the measures described above and by requiring compliance with the City’s Floodplain Management Ordinance (Saratoga Code, Article 16-66). Public facilities adjoining the 100 year flood plain are shown in Figures S-1 through S-4 at the end of this Element. At the end of the Element insert the Figures referenced above. (xi) Local, state, and federal agencies with responsibility for emergency services flood protection, including special districts and local offices of emergency services. SE pg. 14: section on Flood Control and emergency services. Santa Clara Valley Water District has established an emergency operations center in San Jose to gather and disseminate information, to evaluate existing and potential flood and earthquake conditions, and to advise local communities of corrective measures as necessary. None Necessary (B) Establish a set of comprehensive goals, Discussed below. Discussed below 4 AB 162 Requirement Existing General Plan Provisions Proposed Amendments (if necessary) policies, and objectives based on the information identified pursuant to subparagraph (A), for the protection of the community from the unreasonable risks of flooding, including, but not limited to: (i) Avoiding or minimizing the risks of flooding to new development. Safety Goal 3.0 and subsequent policies reduce the damage to public and private property as a result to flooding. This section also refers all proposed projects to the Water District for review and comments. SE pg. 12: Describes conditions of approval required for tentative subdivision maps. SE pg. 13-14: Explains that Saratoga participates in NFIP, which requires certain city actions to minimize risk. SE does not describe the City’s comprehensive floodplain management ordinance. See text revisions to page 14, discussed above. (ii) Evaluating whether new development should be located in flood hazard zones, and identifying construction methods or other methods to minimize damage if new development is located in flood hazard zones. Safety Goal 3.0 and subsequent policies reduce the damage to public and private property as a result to flooding. This section also refers all proposed projects to the Water District for review and comments. None Necessary (iii) Maintaining the structural and operational integrity of essential public facilities during flooding. The Safety Element addresses emergency preparedness on pg. 33. Safety Goal 5.0 address emergency preparedness and identifies policies that include an update to the city’s Emergency Plan on a regular basis, coordination with local jurisdictions and regional agencies, encourages citizens to take responsibility for their own safety (this includes participation in city sponsored disaster preparedness exercises.) None Necessary 5 AB 162 Requirement Existing General Plan Provisions Proposed Amendments (if necessary) (iv) Locating, when feasible, new essential public facilities outside of flood hazard zones, including hospitals and health care facilities, emergency shelters, fire stations, emergency command centers, and emergency communications facilities or identifying construction methods or other methods to minimize damage if these facilities are located in flood hazard zones. Map 6 of the City’s Emergency Evacuation Plan illustrates evacuation routes and primary places of assembly (Saratoga High School, West Valley College, and the Odd Fellows Home.) The City’s emergency operating centers are also show on the map at City Hall and the Saratoga Fire Station. The figures referenced in the new text addition at page 14 of the Safety Element indicate the relationship of public facilities and flood hazard areas.
