(3) 2035 LQ General Plan - Chapter III (11.19.13)               Chapter  III     NATURAL  RESOURCES        AIR  QUALITY      ENERGY  AND  MINERAL   RESOURCES      BIOLOGICAL  RESOURCES      CULTURAL  RESOURCES      WATER  RESOURCES      OPEN  SPACE  AND            CONSERVATION           AIR  QUALITY   III-­‐1         AIR  QUALITY     PURPOSE   The  Air  Quality  Element  describes  the  physical  causes  of  air  pollution  in   the  region  and  provides  policies  and  programs  that  will  enable  the  City   to  improve  its  air  quality.  Goals,  policies,  and  programs  set  forth  in  this   element  are  intended  to  avoid,  reduce,  or  limit  impacts  to  air  quality   resulting  from  build  out  of  the  General  Plan.     Poor  air  quality  poses  a  human  health  threat,  reduces  visibility  in  the   Valley,  affects  the  views  of  the  surrounding  desert  and  mountains,  and   interferes  with  the  livability  of  La  Quinta  for  residents  and  visitors.       The  Air  Quality  Element  is  not  a  stand-­‐alone  element,  but  part  of  an   interrelated  group  of  elements  within  the  General  Plan  that  all  strive  to   preserve  and  enhance  the  quality  of  life  in  La  Quinta.  To  that  end,  the   City  has  prepared  a  Greenhouse  Gas  Reduction  Plan  which  will  help   new  and  existing  development  reduce  greenhouse  gas  emissions.       The  Air  Quality  Element  is  directly  related  to  the  Land  Use  Element,   Traffic  &  Circulation  Element,  and  Open  Space  Element.  The  Land  Use   and  Circulation  Elements  have  the  greatest  effect  on  the  Air  Quality   Element  because  they  have  the  most  direct  relationship  to  vehicle  trips   –  the  largest  source  of  air  pollution  in  the  City.     BACKGROUND   The  Coachella  Valley,  including  the  City  of  La  Quinta,  is  located  within   the  Salton  Sea  Air  Basin  (SSAB)  and  is  within  the  jurisdiction  of  the   South  Coast  Air  Quality  Management  District  (SCAQMD).  The   SSAB  shares  boundaries  with  the  San  Diego  Air  Basin  to  the   west,  the  South  Coast  Air  Basin  to  the  northwest,  and  the   Mojave  Desert  Air  Basin  to  the  north.     Air  quality  in  the  City  is  a  result  of  local,  regional   and   area-­‐wide   conditions.     Air   quality   has   deteriorated  in  the  Coachella  Valley  over  the   last   few   decades   due   to   local   growth,         AIR  QUALITY   III-­‐2   development,  industry  and  construction  activities,  as  well  as  sources   outside   of   the  Valley,  particularly   from   the   South   Coast   Air   Basin   located  west  of  the  region.       Regulatory  Environment   Ambient  air  quality  standards  have  been  established  by  both  federal   and   state  (California)  governments   to   monitor   and   regulate   air   pollutants  and  protect  people  and  the  environment  from  the  effects  of   poor  air  quality.  At  the  regional  level,  management  districts  measure   and   monitor   air   pollution   and   develop   strategies   for   reducing   air   pollution.  Local   governments,   through   ordinances,   programs,  and   policies,  can   help   reduce   impacts   to   air   quality.   A   comparative   summary  of  the  regulatory  environment  is  shown  in  Table  III-­‐1.       Table  III-­‐1   Authorizing  Legislation  &  Implementing  Agencies  for  Air  Quality   Government  Legislation  Implementing   Agencies   Federal  Clean  Air  Act  US

 Document  for  Addressing  Air  Quality  Issues  in  General  Plans  and   Local  Planning,  SCAQMD,  May  6,  2005     Federal  Regulation1   At  the  federal  level,  the  U.S.  Environmental  Protection  Agency  (EPA)  is   charged   with   reducing   emissions   from   federally   controlled   sources   such  as  commercial  aircraft,  trains,  and  marine  vessels,  and  has  also   created  automobile  emission  standards  for  forty-­‐nine  states.  The  EPA   has  been  able  to  enforce  emission  standards  through  the  passage  of                                                                                                                   1    “2007   Air   Quality   Management   Plan,”   South   Coast   Air   Quality   Management   District,  June  1,  2007.     AIR  QUALITY   III-­‐3   the   1963   Clean   Air   Act   (CAA).   More   recently,   the   EPA   has   become   responsible  for  regulating  greenhouse  gas  emissions.       The   EPA   is   responsible   for   setting   the   National   Ambient   Air   Quality   Standards  (NAAQS)  for  criteria  pollutants.  The  NAAQS  has  established   primary  and  secondary  standards  for  six  criteria  air  pollutants  used  to   protect  the  health  and  welfare  of  citizens  and  the  economy.  Primary   standards  are  designed  to  protect  sensitive  sectors  of  the  population   such  as  children  and  the  elderly.  Secondary  standards  were  established   to  protect  economic  entities,  such  as  crops,  buildings,  and  visibility.       State  Regulation   The  State  of  California  has  created  air  quality  regulation  through  the   California  Clean  Air  Act  (CCAA),  which  became  effective  on  January  1,   1989.   The   CCAA   establishes  ambient   air   quality   standards   similar   to   NAAQS,  and  sets  forth  deadlines  for  air  management  districts  which   are  not  attaining  the  standards  to  reach  attainment  status.  The  CCAA   also  established  the  California  Air  Resources  Board  (CARB)  to  oversee   regional  air  pollution  and  develop  State  ambient  air  quality  standards,   which   are   generally   more   stringent   than   federal   standards.   CARB   advises   and   evaluates   the   efforts   of   local   and   regional   air   pollution   control  agencies  and  districts.  Districts  that  are  in  noncompliance  with   federal   and   state   standards   are   encouraged   to   prepare   State   Implementation  Plans  (SIP)  to  help  meet  the  federal  and  state  ambient   air  quality  standards.       The  passage  of  the  California  Global  Warming  Solutions  Act  (AB  32)  in   2006  made   CARB   the   responsible   state   agency   for   monitoring   and   reducing   greenhouse   gas   (GHG)   emissions   at   the   state   level,   by   establishing  an  annual  reporting  program  of  emissions  for  significant   sources.   It   also   set   limits   to   cut   the   state’s   GHG   emissions   to   1990   levels  by  2020.       Finally,  the  Governor’s  Executive  Order  S-­‐3-­‐05,  enacted  on  June  1,  2005,   takes  California’s  commitment  to  GHG  reductions  one  step  further.  It   resolves  to  achieve  statewide  emission  reductions  that  are  80%  below   1990  levels  by  2050.     Regional  Regulation   The  City  and  its  Sphere  of  Influence  are  regulated  on  a  regional  level  by   the  South  Coast  Air  Quality  Management  District  (SCAQMD).  SCAQMD   has   jurisdiction   over   approximately   10,743   square   miles   throughout   Southern   California   and   regulates   air   quality   standards   for   three   different  air  basins,  including  the  South  Coast  Air  Basin,  Mojave  Desert         AIR  QUALITY   III-­‐4   Air   Basin,   and  Salton   Sea   Air   Basin.   The   City   of   La   Quinta   and   surrounding  Coachella  Valley  region  are  located  within  the  Salton  Sea   Air  Basin  (SSAB).  The  Salton  Sea  Air  Basin  is  generally  bounded  on  the   west  by  the  San  Jacinto  Mountains  and  on  the  east  by  the  eastern   edge  of  the  Coachella  Valley.                                       The   SCAQMD   is   responsible   for   the   overall   development   and   implementation   of   the   Air   Quality   Management   Plan   (AQMP).   The   AQMP  is  a  comprehensive  plan  that  complies  with  state  and  federal   requirements   for   ensuring   air   quality   improvement.   The   latest   plan,   approved   in   2007,   builds   upon   previous   plans  and   provides   comprehensive   strategies   to   control   pollution   from   mobile   sources,   stationary   sources   and   area   sources.   It   also   proposes   policies   and   measures   to   achieve   federal   standards   for   healthful   air   quality   throughout  the  District.       The   Salton   Sea  Air  Basin   has   been   in   non-­‐compliance   with   federal   standards  for  ozone,  and  has  been  classified  as  a  “serious”  ozone  non-­‐   attainment  area.  The  region  has  also  historically  been  designated  as  a   serious   non-­‐attainment   area   for   particulate   matter   of   10   microns   or   less,  known  as  PM10.  Blown  sand  is  the  primary  source  of  PM10  in  the   City  and  the  Valley.  In  2002,  the  Coachella  Valley  State  Implementation   Plan   (CVSIP)   was   prepared   and   implemented   by   all   Valley   cities  to   reduce  the  amount  of  blown  sand  and  dust  in  the  Valley.  Since  the   approval   of   the   2003   CVSIP   by   the   EPA,   the   Coachella   Valley   has   successfully  reduced  the  amount  of  PM10  in  the  air  and  meets  current   South  Coast  Air  Quality   Management  District   Jurisdiction     AIR  QUALITY   III-­‐5   federal  standards.  However,  the  Environmental  Protection  Agency  has   not  yet  re-­‐designated  the  PM10  classification  for  the  Coachella  Valley.     Regionally,  the  Coachella  Valley  Association  of  Governments  (CVAG)   coordinates  the  management  of  PM10  for  all  Coachella  Valley  cities.  It   developed  a  model  management  plan  which  has  been  implemented   throughout  the  area.  As  a  member  of  CVAG,  the  City  of  La  Quinta  is   involved  in  the  regional  management  of  air  quality.       Local  Regulation   This  Element  provides  the  City  of  La  Quinta  with  goals,  policies,  and   programs  to  implement  improvements  to  its  air  quality.  The  City  is  also   meeting   the   requirements   of   AB32   by   preparing   a   Greenhouse   Gas   Reduction   Plan,   which   establishes   its   current   emissions  and   sets   targets  for  long-­‐term  reductions.  Community-­‐wide  activities  in  the  City   generated   an   estimated   1,228,050   metric  tons   of   carbon   dioxide   equivalence  in  2005.  Reduction  targets  in  the  Plan  strive  to  achieve  10%   below  2005  levels  by  2020.  To  reach  those  targets,  the  Plan  includes  a   wide  range  of  implementation  tools  which  can  be  implemented  by  City   officials,  residents  and  business  owners.     Regulated  Pollutants   Regulated  pollutants  fall  under  three  categories,  including  criteria  air   pollutants,  toxic  air  contaminants  (TAC),  and  greenhouse  and  ozone   depleting   gases.   Each   type   of   pollutant   is   measured   and   regulated   differently.   Criteria  air  pollutants   are   measured   by   sampling   concentrations  in  the  ambient  air,  whereas  toxic  air  contaminants  are   measured  at  the  source  and  in  the  atmosphere.  Greenhouse  and  ozone   depleting  gases  do  not  have  established  thresholds,  but  are  subject  to   federal   and   regional   policies   for   reduction.2  AB32,   for   example,   establishes  standards  for  targeted  greenhouse  gas  reduction  goals.     Criteria  Pollutants   Criteria   pollutants   are   air   pollutants   for   which   federal   and   state   air   quality  standards  exist.  Federal  and  state  ambient  air  quality  standards   exist   for   lead,   sulfur   dioxide,   carbon   monoxide,   nitrogen   dioxide,   ozone,  and  suspended  particulate  matter.  The  California  Air  Resource   Board  also  has  standards  for  hydrogen  sulfide,  sulfates,  vinyl  chloride,   and  visibility-­‐reducing  particles.  Table  III-­‐2,  below,  provides  a  summary   of  primary  sources  and  effects  of  the  NAAQS  Criteria  Pollutants.                                                                                                                   2    Guidance  Document  for  Addressing  Air  Quality

 Quality  Issues  in  General  Plans  and   Local  Planning,  SCAQMD,  May  6,  2005.     Toxic  Air  Contaminants   Toxic   Air  Contaminants   (TACs)   are   considered   “non-­‐criteria”   air   contaminants  because  no  ambient  air  quality  standards  exist  for  them.   There  are  numerous  TACs  emitted  into  the  air,  and  exposure  to  them  is   linked   to   cancer,   birth   defects,   genetic   damage   and   other   adverse   health  conditions.  Short-­‐term  exposure  is  known  to  cause  acute  health   effects  such  as  nausea,  skin  irritation,  and  respiratory  illness.         Greenhouse  Gases   Greenhouse   gases,   such   as   carbon   dioxide,   methane,   nitrous   oxide,   halons,   chlorofluorocarbons,   and   hydro-­‐chlorofluorocarbons,   are   released  into  the  atmosphere  by  both  natural  processes  and  human   activities.  These  gases  are  termed  “greenhouse  gases”  because  they   trap   heat  and   are   responsible   for   the   global   increase   in   surface   temperature  observed  over  the  last  decade.  There  is  much  debate  over   what   the   effects   of   climate   change   will   be,   but   there   is   a   general     AIR  QUALITY   III-­‐7   consensus   that  emissions  levels  need   to   be   reduced   in   order   to   minimize   air   pollution   and   limit   the   amount   of   carbon   dioxide   and   other  pollutants  that  are  emitted.       Greenhouse  Gas  Reduction  Plan   La  Quinta  is  committed  to  reducing  greenhouse  gas  emissions,  and  has   prepared  a  Greenhouse   Gas   Reduction   Plan   as   a   first   step   towards   achieving   this   goal.   The  Greenhouse  Gas  Reduction  Plan   includes   a   comprehensive  inventory  of  greenhouse  gas  emissions  generated  City-­‐ wide,  including  those  generated  by  local  government  activities.    Future   emissions  of  greenhouse  gases  are  projected,  reduction  targets  set,   and  policies  and  programs  are  proposed  as  part  of  the  Greenhouse  Gas   Reduction   Plan.  The   Plan   is   a   toolbox   the   City   will   use   to   meet   mandated  reductions.     To  be  consistent  with  AB  32  and  executive  order  S-­‐3-­‐05,  the  reduction   target  is  to  achieve  1990  level  emissions  by  2020,  and  80%  below  1990   levels  by  2050.       While  more  stringent  requirements  for  building  standards  and  vehicle   fuel  efficiency  are  being  enacted  on  a  statewide  level,  such  as  through   updates  to  the  California  Building  Code  (Title  24),  and  SB  375,  the  City   will  comply  with  statewide  efforts  and  act  locally  to  monitor,  evaluate,   and  amend  local  policies  and  programs  in  order  to  achieve  mandated   emission  reductions.     Ambient  Air  Quality  Standards   Federal   and   state   air   quality   standards   established   for   criteria   pollutants  are  designed  to  protect  that  segment  of  the  population  that   is  most  susceptible  to  respiratory  distress  or  infection,  including  the   elderly,  children,  asthmatics,  or  those  who  are  weak  from  disease  or   illness.     State   standards   are   generally   more   restrictive   than   federal   standards,  particularly  with  regard  to  carbon  monoxide  and  particulate   matter.  The  General  Plan  EIR  describes  the  federal  and  state  standards   in  place  at  the  time  this  General  Plan  is  adopted.       The   SCAQMD   operates   and   maintains   two   regional   air   quality   monitoring  stations  in  the  Coachella  Valley,  including  one  at  a  Palm   Springs  Fire  Station  and  one  in  the  City  of  Indio,  off  Jackson  Street.   These   monitoring   stations   determine   whether   existing   ambient   air   quality   complies  with   current   standards.   The   nearest   monitoring   station   to   La   Quinta,   in   Indio,   monitors   contaminant   levels   and   meteorological   conditions   on   a   daily   basis.   Ozone   and  particulate   matter   are   the   primary   pollutants   of   concern   in   La   Quinta   and         AIR  QUALITY   III-­‐8   represent  the  greatest  threats  to  air  quality  and  human  health  in  the   Coachella  Valley.  The  region  is  experiencing  a  decreasing  trend  in  the   number  of  days  that  exceed  ozone  and  PM10  levels.       Sensitive  Receptors     Sensitive   receptors   are   people   or   land   uses   that   may   be   especially   subject   to   respiratory   stress   and/or   significant   adverse   impacts   as   a   result  of  exposure  to  air  contaminants.  The  CARB  designates  people   with  cardiovascular  and  chronic  respiratory  diseases,  children  under  14,   seniors  over  65,  and  athletes  as  sensitive  receptors.  The  City’s  appeal   as  a  retirement  destination  and  resort  community  implies  that  a  major   portion   of   its   residents   and   visitors   are   potentially   susceptible   to   respiratory   distress   from   elevated   concentrations   of   air   quality   pollutants.   Accordingly,   hospitals,   nursing   and   retirement   homes,   schools,   daycares,   playgrounds,  parks,   athletic   facilities,  residential   structures,  and  hotels  are  all  considered  sensitive  land  uses.     Climatic  Conditions  in  the  Coachella  Valley     The   City   of   La   Quinta,  the   City’s  Sphere   of   Influence,   and   the   surrounding   region   are   located   in   a   hot,  arid   desert   climate.   The   surrounding  mountains  block  coastal  influences,  creating  an  area  of   low  rainfall.  The  Valley  floor  typically  receives  an  average  of  four  inches   of   rain   per   year.   Temperatures   frequently  exceed   100º   F   during   the   summer  and  can  occasionally  fall  below  freezing  during  the  winter.  The   prevailing  wind  patterns  during  spring  and  summer  blow  west  to  east   and  are  caused  by  a  desert  thermal  low-­‐pressure  area  drawing  cooler,   denser  coastal   air   through   the   San   Gorgonio   Pass.   During   fall   and   winter  months,  climatic  conditions  change  as  strong  dry  northeasterly   Santa  Ana  winds  blow  air  toward  the  coast.  These  strong  wind  events   suspend  and  transport  large  quantities  of  particulate  matter,  including   sand  and  dust,  which  can  reduce  visibility,  damage  property  and  pose  a   significant  health  threat.  The  prevailing  wind  patterns  also  draw  in  air   pollution  generated  in  the  South  Coast  Air  Basin  west  of  the  Coachella   Valley.       Regional  Pollutants  of  Concern     Compared  to  air  basins  west  of  the  Coachella  Valley,  the  City  of  La   Quinta   has   good   air   quality.   High   levels   of   ozone   and  particulate   matter,   which   are   described   below,   are   the   primary   pollutants   of   concern  in  La  Quinta  and  represent  the  greatest  threat  to  air  quality   and  human  health  in  the  Coachella  Valley.           AIR  QUALITY   III-­‐9   Ozone  (O3)     Ozone  is  a  pungent,  colorless,  toxic  gas  formed  when  byproducts  of   internal   combustion   engines   react   in   the   presence   of   ultraviolet   sunlight.    Ozone  is  emitted  daily  from  the  operation  of  automobiles.         The  Coachella  Valley  has  a  history  of  occasionally  exceeding  state  and   federal  ozone  standards;  however,  trends  do  show  a  slight  decrease  in   the   concentration   over   the   past   decade.   The   Coachella   Valley   is   classified  as  a  “serious”  ozone  non-­‐attainment  area  under  the  Federal   Clean   Air   Act.   Under   current   regulatory   plans,   the   area   must   demonstrate  attainment  of  the  federal  ozone  air  quality  standard  by   June  15,  2013.3  Local  monitoring  for  ozone  indicates  that  federal  ozone   exceedances  in  the  Coachella  Valley  are  largely  the  result  of  pollutant   transport  from  the  South  Coast  Air  Basin,  through  the  Banning  Pass.     Improving  ozone  levels  in  the  Coachella  Valley  will  be  partly  dependent   upon   reduced   ozone   emissions   in   the   South   Coast   Air   Basin.   Simulations  of  ozone  episodes,  prepared  by  SCAQMD,  show  that  the   federal   8-­‐hour   standard   will   be   attained   in   the   Coachella   Valley   by   2018.4  This  8-­‐hour  standard  is  currently  the  only  federal  standard  for   ozone.     PM10  Emissions   Particulate   matter   less   than   10   microns   in   diameter  (PM10)  includes   suspended   particles   of   dust,   sand,   metallic   and   mineral   substances,   road-­‐surfacing  materials,  pollen,  smoke,  fumes  and  aerosols.  Natural   erosion  and  sand  migration  caused  by  strong  winds  in  the  Coachella   Valley  generate  most  PM10  in  the  La  Quinta  area.  Grading  and  other   activities  associated  with  construction  are  also  significant  contributors   to  dust  generation.  Windborne  particles  may  be  further  pulverized  by   motor  vehicles  on  roadways,  where  they  are  re-­‐suspended  in  the  air.   PM10  particles  can  pass  through  the  filtering  system  of  the  lungs  and   directly   irritate   lung   tissues,   potentially   resulting   in   serious   health   problems.     Although  the  Coachella  Valley  has  a  history  of  elevated  PM10  levels,   local   government   agencies,   private  and   public   stakeholders,   and   SCAQMD  have  developed  State  Implementation  Plans,  rules,  and  local   dust  control  ordinances  to  bring  the  Coachella  Valley  into  attainment.   The   Coachella   Valley   State   Implementation   Plan   was   adopted   and   approved  by  the  EPA  on  April  18,  2003  and  includes  control  measures                                                                                                                   3    As  described  in  the  2007  Air  Quality  Management  Plan,  prepared  by  SCAQMD  on   June  1,  2007,  p.8-­‐1,  this  will  be  accomplished  using  a  photochemical  grid  model.   4    2007  Air  Quality  Management  Plan,  SCAQMD,  June  1,  2007,  p.8-­‐10         AIR  QUALITY   III-­‐10   to  reduce  PM10.5  These  measures  have  been  effective  in  reducing  the   concentration  of  PM10  throughout  the  Coachella  Valley.  Although  the   valley  currently  meets  attainment  standards,  the  EPA  has  not  yet  re-­‐ designated  the  PM10  classification  for  the  Coachella  Valley.     Pollutant  Control  Measures  Implemented  by  La  Quinta   In   2003,   to   reduce   the   impacts   of   local   fugitive   dust   and   PM10   emissions,  the  City  of  La  Quinta  adopted  Fugitive  Dust  (PM10)  Control   Ordinance  No.  391  (Chapter  6.16  of  the  La  Quinta  City  Municipal  Code).   The   ordinance   establishes   minimum   dust   control   requirements   for   construction   and   demolition   activities   and   other   land   uses.   Dust   control  measures  set  forth  in  the  ordinance  include  the  preparation   and  approval  of  a  Fugitive  Dust  Control  Plan;  reductions  in  vehicular   speeds  on  unpaved  roads  and  at  construction  sites;  the  application  of   chemical   and/or   vegetative   dust   suppressants   and   stabilizers;   and   paving  of  parking  lots  and  roadways.  The  City  will  not  issue  a  grading   or  demolition  permit  without  an  approved  Fugitive  Dust  Control  Plan.   The   City   has   the   authority   to   monitor   and   inspect   grading   and   demolition   activities   to   ensure   that   the   measures   identified   in   each   fugitive  dust  mitigation  plan  are  properly  implemented.6       The  City  also  participates  in  regional  air  pollution  reduction  measures   established  and  maintained  through  the  Coachella  Valley  Association  of   Governments.     PLANNING  FOR  THE  FUTURE   The  City  of  La  Quinta  will  continue  to  act  locally  to  meet  existing  and   future  state  and  federal  air  quality  regulations.  La  Quinta  is  exploring   alternative  energy  options,  such  as  wind  turbines,  geothermal  systems,   and   solar   energy,   electric   and   alternative   fuel   vehicles,   and   green   building   technology,  as   viable   options   for  enhancing   air   quality   by   reducing  greenhouse  gas  emissions  and  other  air  pollutants.  A  major   effort   of   this   undertaking   is   the   implementation   of   the   La   Quinta   Greenhouse  Gas  Reduction  Plan.

 GOALS   As  described  above,  this  Element  relates  to  others  in  this  General  Plan.   The  following  Goals,  and  their  associated  policies  and  programs,  are   closely  related  to  those  of  this  Element.     GOAL  SC-­‐1:  A  community  that  provides  the  best  possible  quality  of  life   for  all  its  residents.                      ENERGY  AND  MINERAL  RESOURCES   III-­‐15         ENERGY  AND  MINERAL  RESOURCES     PURPOSE     Energy   and   mineral   resources   are   components   of   the   City’s   natural   resources.  Energy  resources  include  electric  power,  natural  gas  service,   and  propane  gas  service,  which  is  limited  to  the  La  Quinta  Cove  and   some   areas   in   the   Sphere   of   Influence   (SOI).   Recent   changes   in   California  law  and  residents’  concerns  regarding  energy  efficiency  and   conservation  have  placed  a  particular  focus  on  energy  use  now  and  in   the  future.  Mineral  resources  in  the  region  consist  primarily  of  sand   and  gravel  for  construction,  which  have  not  been  mined  in  the  City  or   its  SOI  in  many  years.  Government  Code  Section  65560  requires  that   cities  consider  in  their  General  Plans  lands  for  the  managed  production   of  natural  resources.     The  Energy  and  Mineral  Resources  Element  addresses  these  resources,   and  their  relationship  to  the  City’s  long-­‐term  growth.       BACKGROUND     Energy  Resources     Electricity  is  provided  to  the  City  and  its  SOI  by  the  Imperial  Irrigation   District  (IID),  a  local  taxing  district  which  provides  electric  power  to  the   eastern  Coachella  Valley  and  Imperial  County.  IID  generates  over  60%   of  its  power  from  a  number  of  facilities,  including  the  Coachella  Gas   Turbine  facility  in  Coachella,  and  its  transmission  facilities  include  its   Green  Path  system,  which  transmits  geothermal  energy  produced   in  Imperial  County.  IID  has  diversified  its  portfolio  and  is  striving   to   achieve  its   goal   of   deriving  a   minimum   of   20%   of   its   electricity   from   alternative   energy   sources,  such   as   geothermal,  solar  and  wind  energy.       In  2005  in  La  Quinta,  a  total  of  9,750  customers   consumed  222,576,000  kilowatt  hours  (kWh)   of   electricity.   Single   family   homes   and   condominiums   consumed   on   average         ENERGY  AND  MINERAL  RESOURCES   III-­‐16   17,917  kWh  each,  and  were  the  single  largest  user  of  electricity  in  the   City.  The  City  has  committed  to  reducing  its  consumption  of  electricity   through  a  number  of  programs,  discussed  below  and  in  the  Livable   Community  Element.  .       Natural   gas   is   provided   to   the   City   by   The   Gas   Company,   which   transports  natural  gas  to  the  Coachella  Valley  through  regional  high   pressure  lines.  Limiting  stations  transfer  the  gas  to  supply  lines  with   reduced  pressure,  which  feed  local  accounts.  Natural  gas  is  the  primary   energy  source  for  water  heaters,  cooking  and  heating.  In  2005,  the  City   consumed  692,150,000   cubic   feet   of   natural   gas.  In   2009,   the   City   consumed  an  estimated  950  million  cubic  feet  of  natural  gas.     In  areas  where  natural  gas  service  is  not  available,  including  portions  of   the  La  Quinta  Cove  and  older  homes  in  the  SOI,  propane  gas  is  used   instead.  Propane  is  supplied  by  private  companies  which  contract  with   individuals  and  businesses  to  fill  on-­‐site  tanks  for  private  use.     Alternative  Energy   The  western  end  of  the  Coachella  Valley  has  produced  wind  energy  for   years.  The  City  and  its  SOI  do  not  have  sustained  winds  sufficient  to   accommodate  commercial  wind  energy  development,  but  they  have,   and   will   continue,  to   benefit   from   this   resource.   State   and   federal   programs  have  expanded  the  potential  for  wind  energy  development,   which  is  currently  being  considered  for  expansion  on  federal  lands  in   the  region.     As   described   above,   geothermal   energy   is   in   production   in   Imperial   County  and  is  currently  part  of  the  IID  energy  portfolio.  Its  expansion  is   also  likely  during  the  life  of  this  General  Plan,  as  additional  sources  are   tapped   and   harnessed.  More   studies   are   required   to   determine   whether   geothermal   energy   production   is   feasible  locally.   However,   the  City  can  expect  to  continue  to  use  geothermal  energy  produced   elsewhere  well  into  the  future.     The   City’s   abundant   sunshine   makes   solar   energy   use   the   most   promising  alternative  energy  production  method  for  the  future.    In  the   past,  consumer-­‐level  solar  energy  systems  were  costly  and  unreliable.   The  latest   technology,   however,   has  reduced   costs  and  improved   efficiency.  During  the  life  of  this  General  Plan,  it  can  be  expected  that   solar   energy   use   for   residences   and   businesses   will   increase   substantially.       ENERGY  AND  MINERAL  RESOURCES   III-­‐17   Energy  and  Greenhouse  Gases   In   recent   years,   concerns   regarding   the   existence   and   increase   in   greenhouse   gases   have   grown.   Greenhouse   gases   include   carbon   dioxide,   methane,   nitrous   oxides   and   fluorinated   gases   which   have   been  shown  to  damage  our  atmosphere  and  increase  global  warming.   Although  the  primary  source  of  greenhouse  gases  is  the  automobile,   the   creation   and   consumption   of   energy   also   produces   greenhouse   gases.  In  2006,  the  State  legislature  passed,  and  the  Governor  signed,   the   California   Global   Warming   Solution   Act,   which   requires   that   all   greenhouse  gas  emissions  be  reduced  to  1990  levels  by  2020,  and  that   reductions  of  80%  below  1990  levels  be  achieved  by  2050.  By  reducing   its  consumption  of  energy,  the  City  will  help  to  meet  these  targets   during  the  life  of  this  General  Plan.     Mineral  Resources   Mineral  resources  in  the  City  and  the  region  consist  primarily  of  sand   and  gravel  which  has  been  transported  by  wind  and  rain  into  the  Valley   from  surrounding   mountains   over   millennia.   California   requires   that   mineral   resources   be   identified  and   that   the   mining   of   identified   resources  be  protected.  The  California  Department  of  Conservation,   Division  of  Mines  and  Geology  has  mapped  the  region’s  resources  and   identified  three  Mineral  Resource  Zones  in  the  City:     MRZ-­‐1  lands  are  areas  where  adequate  information  indicates  that  no   significant  mineral  deposits  are  present,  or  where  it  is  judged  that  little   likelihood  for  their  presence  exists.     MRZ-­‐2  lands  include  areas  where  adequate  information  indicates  that   significant  mineral  deposits  are  present,  or  where  it  is  judged  that  a   high  likelihood  for  their  presence  exists.     MRZ-­‐3  lands  are  areas  containing  mineral  deposits,  the  significance  of   which  cannot  be  evaluated  from  available  data.     As  shown  in  Exhibit  III-­‐1,  most  of  the  City  and  its  Sphere  lie  within  MRZ-­‐ 1,  while  lands  south  of  Avenue  60  have  not  been  studied.         ENERGY  AND  MINERAL  RESOURCES   III-­‐18     THIS  PAGE  INTENTIONALLY  LEFT  BLANK         ENERGY  AND  MINERAL  RESOURCES   III-­‐20     PAGE  NUMBER  SPACER  -­‐  PULL  FROM  DOC     ENERGY  AND  MINERAL  RESOURCES   III-­‐21     Only   one   area   of   the   City   is  identified   as   having  the  potential   for   mineral   resources   (please   see  Exhibit   III-­‐1).   The   MRZ-­‐2   zone   was   previously   a   quarry  site,   but  has  been   developed   as   a   country   club   community  for   several   years.   The   future   development   of   the   City’s   hillsides  will  be  unlikely,  as  they  are  designated  for  Open  Space  and  are   not  expected  to  develop.  No  other  lands  are  identified  in  the  City  or  its   Sphere   as   having   the   potential   to   harbor   mineral   resources.  Lands   south  of  Avenue  60  have  not  been  studied  yet.  If  they  prove  to  contain   mineral  resources,  the  City  will  diligently  and  responsibly  manage  these   mineral  resources.     PLANNING  FOR  THE  FUTURE   The  continued  growth  of  the  City  and  its  Sphere  will  require  additional   energy  resources.  Although  IID  and  The  Gas  Company  are  expected  to   continue  to  supply  the  City  and  its  Sphere  with  electricity  and  natural   gas,   respectively,   the   City   is   also   committed  to   the  conservation   of   these  resources  and  to  reducing  energy  usage  to  the  greatest  extent   possible.   Additionally,  the   City   has   developed   a   Greenhouse   Gas   Reduction   Plan   which   establishes   reduction   targets   and   implementation  programs  to  help  the  City  meet  the  requirements  of   the   California   Global   Warming   Solutions   Act.  While   the   policies   and   programs  in  this  element  are  specifically  focused  on  energy  resources,   the  Livable  Community   Element   includes   detailed   policies   and   programs  to  achieve  global  warming  goals.             ENERGY  AND  MINERAL  RESOURCES   III-­‐22   GOALS,  POLICIES  AND  PROGRAMS   GOAL  EM-­‐1     The  sustainable  use  and  management  of  energy  and  mineral  resources.      Policy  EM-­‐1.1   Strongly  encourage  conservation  of  energy

 Resources  Element  provides  background  information  on   the  City’s  diverse  natural  habitats  and  the  species  which  live  in  these   habitats.   It   provides   information   on   the   Coachella   Valley   Multiple   Species   Habitat   Conservation   Plan   (CV  MSHCP)  and   those   species   covered  by  the  Plan  which  may  occur  in  the  City.  The  Element  also   includes   goals,   policies   and   programs   to   direct   the   preservation   of   valuable  habitat  and  the  species  which  occur  in  the  City,  and  to  comply   with  federal,   state,   and  regional   efforts   associated   with   biological   resource  preservation.     California   Government   Code   Section   65302(d)   requires   that   the   General  Plan  include  a  natural  resources  component,  which  addresses,   among   other   issues,   biological   resources.   The   Biological   Resources   Element  directly  relates  to  the  Land  Use  and  Open  Space  elements  and   has  the  potential  to  impact  both.  In  addition,  native  species  can  be   significantly  affected  by  the  availability  of  water,  tying  this  Element  to   the  Water  Resources  Element.     BACKGROUND   La  Quinta’s  natural  environment  varies  considerably,  as  its  elevation   ranges  from  130  feet  below  sea  level  in  the  southeastern  corner  of  the   Sphere  of  Influence,  to  over  1,700  feet  above  sea  level  in  the  foothills   of  the  Santa  Rosa  Mountains.  The  majority  of  the  City  and  the  Sphere   of   Influence   occur   on  the   Valley   floor,   which   has   a   climate   characterized  by  hot,  dry  summers  and  mild  winters.  Climate  has   affected   soils,   and   therefore,  the   habitats   which   can   be   sustained  in  the  City.  Most  of  the  11  soil  types  found  in  the   City  and  its  Sphere  are  sandy  in  nature  and  well-­‐drained.   Rock  and  rubble  occur  in  the  Santa  Rosa  foothills.   (Please   see   the   Soils   and   Geology   Element   for   greater  detail  on  soil  types  in  the  City.)             BIOLOGICAL  RESOURCES   III-­‐26   Naturally  occurring  habitat  within  the  City  and  on  the  Valley  floor  has   largely   disappeared  due   to   the   impacts   of   agriculture   and   urban   development.  The  majority  of  the  City’s  vegetation  consists  of  non-­‐ native   ornamental   plants   which   have   been   introduced   via  urban   development.   Native   habitat   still   occurs   on   the   slopes   of   the   Santa   Rosas,  and  lands  which  are  designated  as  Open  Space  on  the  City’s   Land  Use  Map,  and  these  areas  have  little  potential  for  development.     Common  Native  Plant  Species   The   base   of   the   foothills,  drainages   and   streams   in   the   City   consist   primarily  of  Sonoran  Creosote  Bush  Scrub,  Sonoran  Mixed  Woody  and   Succulent  Scrub,  and  Desert  Dry  Wash  Woodland.  Sonoran  Creosote   Bush  Scrub  is  the  most  common  plant  community  in  the  City  and  the   Coachella   Valley,  and   is   dominated   by   Creosote   Bush,   Burrobush,   Brittlebush  and  similar  common  species.  This  plant  community  also  has   the   highest   concentration   of   annual   desert   wildflowers,   which   can   result  in  bright  explosions  of  color  in  the  spring.  Sonoran  Mixed  Woody   and  Succulent  Scrub,  which  occurs  primarily  at  the  base  of  the  Santa   Rosa  Mountains,  is  similar  to  Creosote  Bush  Scrub,  but  has  a  higher   plant   density   and   greater   variety   of   species,   including   cacti   and   succulents.   This   habitat   can   include   Golden   Cholla,   Buckhorn   Cholla,   Beavertail,   California   Barrel   Cactus   and   Ocotillo.   Desert   Dry   Wash   Woodland   is   dominated   by   Blue   Palo  Verde,  Ironwood   and   Smoketree,   which   are   all   well   adapted   to   intermittent  water  flows  in  the  washes  and  drainage  courses  which   occur  in  the  City’s  southern  end.       The  northern  area  of  the  City  was  originally  wind  blown  sandy  habitat,   including  desert  dunes  and  sand  field  habitats.  The  development  of   lands   to   the   northwest  over   time  has  reduced   the   amount   of  sand   transported  to  these  areas  and  resulted  in  stabilized  sand  habitats  that   are  more  likely  to  support  non-­‐native  and  invasive  species,  which  have   degraded  the  natural  communities.  Little  of  this  habitat  still  occurs,   and  those  parcels  which  are  still  vacant  are  generally  isolated.  None  of     BIOLOGICAL  RESOURCES   III-­‐27   the  sand  field  habitats  within  the  City  have  been   identified  for  preservation  in  the  CV  MSHCP.     In  the  Sphere  of  Influence,  Desert  Saltbush  Scrub   occurs  on  soils  which  are  poorly  drained  and  have   high  salinity  or  alkalinity,  most  often  occurring  on   long-­‐fallow   agricultural   lands.   In   addition   to   the   native  Big  Saltbush,  Allscale  and  Honey  Mesquite,   this   habitat   often   supports   non-­‐native   alkali   tolerant  species.     Common  Native  Wildlife   Native  species  in  the  City  and  its  Sphere  of  Influence  can  be  divided   into  two  types:  those  which  have  adapted  to  the  disturbed  sand  field,   saltbush  scrub,  agricultural  and  urban  development;  and  those  which   occur  in  the  less  disturbed  habitats  that  currently  exist  on  the  southern   and  western  edges  of  the  City  and  Sphere.  Insects  common  in  the  City   and  Sphere  include  Harvester  Ants,  Creosote  Bush  Grasshopper  and   Black   Widow   Spider.   Amphibians   include   California   Toad   and   Pacific   Tree   Frog;   while   the   Zebra-­‐tailed   Lizard,   Desert   Horned   Lizard,   California   Kingsnake,  and   Colorado   Desert   Sidewinder   are   common   reptiles.  The  City  and  its  Sphere  also  support  a  number  of  native  birds,   including   the   House   Finch   and   House   Sparrow,   Abert’s   Towhee,   Mourning  Dove  and  Red-­‐tailed  Hawk.  Common  mammals  include  the   Black-­‐tailed  Jackrabbit,  Pocket  Mouse  and  California  Ground  Squirrel.  A   complete  listing  of  common  species  found  in  the  City  and  Sphere  is   available  in  the  General  Plan  EIR.     Special  Status  Species   Species  which  are  considered  threatened  or  endangered  under  either   the   California   or   federal   Endangered   Species   Acts  are   called   special   status  species.  The  US  Fish  and  Wildlife  Service  (FWS),  CDFG,  and  the   California  Native  Plant  Society  (CNPS)  all  maintain  lists  of  these  species.   The  Table  III-­‐3  provides  a  list  of  special  status  species  known  to  occur   in   the   City   or  its  Sphere   of

  described   below,   along   with   the   likelihood   of   its   occurrence  in  the  City  and  Sphere.       Glandular  Ditaxis  has  been  identified  at  two  locations   in   the   planning   area,   both   of   which   have   been   developed.   There   is   a   low   potential   for   the   occurrence   of   the   species   in   the   southern   and   western  edges  of  the  City  and  Sphere.  Spring  or  fall   surveys   are   required   for   the  species   following   sufficient  rainfall.     California  Ditaxis  occurs  in  dry  washes,  flood  plains  and  rocky  alluvial   fans.  It   was   previously   identified   west   of   Avenida  Montezuma  and  Calle  Nogales,  in   the   Cove.   There   is   a   moderate   to   high   potential   that   the   species   occurs   in   the   southern   and   western   areas   of   the   City.   Spring  surveys  are  required  for  the  species   following  sufficient  rainfall.     The  Burrowing   Owl  uses   burrows   dug   out   by   other   wildlife,   such   as  the  Kit   Fox,   Desert   Tortoise,  or  Ground  Squirrel;  it  also  uses  man-­‐ made  structures  such  as  piles  of  rubble  or  tree   branches,   pipes   or   buildings.   The   species   is   a   protected  raptor  as  well  as  a  species  of  special   concern,   and   therefore   requires   CDFG   notification   and   approved   mitigation   prior   to   any   activity   which   might   impact   the   species.   The   species   has   the   potential   to   occur   throughout  the  City  and  Sphere,  where  undeveloped  or  fallow  land   occurs.  Site-­‐specific  surveys  are  needed  to  identify  the  species.     The  Prairie  Falcon  is  a  medium  to  large  sized  migratory  raptor  which   winters   in   the   region.   Its   preferred   habitat   is   cliffs  or  steep  rock  ledges  in  the  western  and   southern   parts   of   the   City   and  its  Sphere.   Prairie   Falcons   have   been   identified   at   the   southwestern  end  of  the  City.  The  species  is  a   protected  raptor  as  well  as  a  species  of  special   concern,   and   therefore   requires   CDFG   notification   and   approved   mitigation   prior   to     BIOLOGICAL  RESOURCES   III-­‐31   any  activity  which  might  impact  the  species.  Site-­‐specific  surveys  are   needed  to  identify  the  species.     The  Black-­‐tailed  Gnatcatcher  is  a  small  resident  songbird  which  has   been  identified  at  two  locations  in  the  City,  and  which  is  likely  to  occur   in  the  western  and  southern  portions  of  the  City  and  its  Sphere.  Site-­‐ specific  surveys  are  needed  to  identify  the  species.     The  Loggerhead  Shrike  is  reasonably  common   in   California,   but   has   been   significantly   depleted  in  other  parts  of  the  US.  It  occurs  in   undeveloped   areas,   the   hillsides   in   the   south   and   west,   and   on   the   edges   of   agricultural   fields.   No   specific   study   or   preservation   prescriptions   are   attached   to   the   species.       The  Pocketed  Free-­‐tailed  Bat  has  large  ears  and   long  wings,  and  roosts  in  caves  crevices  and  cliffs.  It  is  likely  to  use  golf   courses  for  foraging  and  drinking.  Since   the   species   uses   rocky   terrain   in   the   Santa  Rosa  Mountains  for  its  roosts,  the   Open   Space   designation   applied   to   these  lands  should  protect  it  from  harm   within  the  City  and  its  Sphere.     Locations  where  the  species  above  have  been  sighted,  and  the  areas   requiring  species-­‐specific  studies  are  shown  in  Exhibit  III-­‐2.         BIOLOGICAL  RESOURCES   III-­‐32       THIS  PAGE  INTENTIONALLY  LEFT  BLANK

  The   Coachella   Valley   Multiple   Species   Habitat   Conservation   Plan   (MSHCP)  has  been  implemented  since  2008.  The  MSHCP  addresses  the   conservation   of   27   species   and   24   vegetation   communities  in   the   Coachella  Valley,  covering  more  than  1.2  million  acres.  The  MSHCP  has   two  primary   goals  –  to   balance   the   protection   of   the   natural   environment  with  the  economic  development  needs  of  the  Valley;  and   to   streamline   compliance   with   California   and   federal   endangered   species  regulations  and  permitting  for  the  species  covered  by  the  Plan.     The   MSHCP   includes   identified   conservation   areas   throughout   the   Valley.  In  La  Quinta,  conservation  areas  are  limited  to  lands  in  the  Santa   Rosa   Mountains   and   its   foothills.   The   MSHCP   quantifies   the   conservation  goals  for  La  Quinta,  as  follows:      2,545  acres  of  Essential  Habitat  for  the  Peninsular  bighorn   sheep    387  acres  of  Conserved  Habitat  for  the  Le  Conte’s  thrasher    1,409  acres  of  Conserved  Habitat  for  the  Desert  Tortoise    76  acres  of  desert  dry  wash  woodland    Conserve  occupied  burrowing  owl  burrows  as  provided  for  in   the  MSHCP  avoidance,  minimization  and  mitigation  measures.     Development   proposed   on   lands   which   are   not   designated   for   conservation  is  required  to  pay  a  mitigation  fee,  which  assures  that   funds  will  be  available  in  the  future  for  the  purchase  of  conservation   lands,  and  which  offsets  the  potential  impacts  of  that  development  on   the  natural  environment.     Streambeds  and  Blueline  Streams   The  primary  ephemeral  stream  through  the  City  is  the  Coachella  Valley   Stormwater   Channel,   known   as   the   Whitewater   River   west   of   Washington  Street.  The  Channel  qualifies  as  both  a  Water  of  the  State   of   California,   and   a  Water   of   the   United   States,   and   therefore   falls   under  the  jurisdiction  of  both  the  California  Department  of  Fish  and   Game   (CDFG)   and   the   US   Army   Corps   of   Engineers   (USACE).   Any   construction   activity   within   the   Channel   requires   consultation   with   both   CDFG   and   the   USACE  and   the   securing   of   permits   from   both   agencies.     A  number  of  smaller,  mostly  unnamed  streams  drain  from  the  Santa   Rosa   Mountains,   including   Bear   Creek,   which   enters   the   City   at   the   south  end   of   the   Cove.   These   drainage   courses  fall   under   the   jurisdiction  of  the  CDFG,  but  are  not  considered  “waters  of  the  United         BIOLOGICAL  RESOURCES   III-­‐36   States,”  as  defined  by  USACE.  Construction  activity  in  these  streams,   including  the  La  Quinta  Evacuation  Channel,  requires  consultation  with   CDFG,  and  may  require  a  permit  prior  to  the  initiation  of  work.         BIOLOGICAL  RESOURCES   III-­‐38     PAGE  NUMBER  SPACER  -­‐  PULL  FROM  DOC     BIOLOGICAL  RESOURCES   III-­‐39   Migratory  Bird  Treaty  Act   Common  and  special  status  birds  in  the  City  and  its  Sphere  are  almost   all  protected  under  the  Migratory  Bird  Treaty  Act  (MBTA).  This  federal   law  prohibits  the  disturbance  of  nests,  eggs  or  incubating  birds  while   nests  are  active.  In  the  City,  the  nesting  period  generally  ranges  from   March  through  August.  Projects  undertaken  during  that  time  must  first   determine  if  active  nests  occur  in  trees  and  bushes  prior  to  removing   them.     PLANNING  FOR  THE  FUTURE   The   City’s   native   biological   environment   on   the   Valley   floor   will   continue  to  shrink  as  development  occurs.  The  City’s  participation  in   the  MSHCP  will  help  to  offset  this  loss  by  acquiring  lands  regionally  for   preservation.  However,  the  City  can  support  the  preservation  of  native   species,   some   of   which   have   proven   to   be   adaptable   to   developed   conditions,  through  the  planting  of  native  plants  and  the  continued  use   of  drought  tolerant  landscaping  techniques,  which  do  not  significantly   increase  the  water  levels  in  the  soil.     The  City  must  also  assure  that  impacts  to  species  not  covered  by  the   MSHCP  do  not  significantly  affect  these  populations  by  requiring  site-­‐ specific  surveys  for  those  species  as  development  is  proposed  in  their   habitats.  Fortunately,  the  majority  of  these  species  occur  at  the  base  of   the  Santa  Rosa  Mountains,  in  areas  which  are  to  be  conserved  under   the  MSHCP,  and  these  uncovered  species  will,  therefore,  receive  de   facto  protection.     GOALS,  POLICIES  AND  PROGRAMS   GOAL  BIO-­‐1

Element   describes   prehistoric,   historic   and   paleontological  resources  in  the  City  and  its  Sphere  of  Influence.  The   City   has   a   rich   history   which  includes   Ancient   Lake   Cahuilla  and   its   fossilized   resources,   Native   American   settlements  and   activity,   and   European   settlement   in   more   recent   times.   The   resources   which   remain  from  each  of  these  time  periods  are  non -­‐renewable,  and  the   continued  development  of  the  City  and  its  Sphere  of  Influence  has  the   potential  to  negatively  impact  artifacts  and  fossils  which  may  occur  in   the  area.     This  Element  describes  the  area’s  history  and  provides  goals,  policies   and   programs   intended   to   assure   that   the   cultural   resources   which   have  been  identified,  and  those  resources  which  may  be  identified  in   the  future,  are  preserved.     BACKGROUND   Prehistoric  Context   It  is  believed  that  early  settlement  by  the  ancestors  of  the  region’s   current   Native   American   peoples,   the   Cahuilla,   occurred   as   early   as   1000  BC.  Anthropologists  have  divided  the  Cahuilla  into  three  groups   based  on  the  geographic  areas  they  occupied  –  the  Pass  Cahuilla  in  the   San  Gorgonio  Pass  and  Palm  Springs  area;  the  Mountain  Cahuilla  in  the   San  Jacinto  and  Santa  Rosa  Mountains  and  the  Cahuilla  Valley;  and  the   Desert  Cahuilla  of  the  eastern  Coachella  Valley.  The  early  Cahuilla  had   many  villages  in  the  area  and  lived  off  local  plants  and  animals  and   the   aquatic   food   available   in   ancient   Lake  Cahuilla.   Lake   Cahuilla  filled  and  receded  several  times,  with  its  last  stand   believed   to   be   about   1650.   In   addition   to   the   lake,   seasonal  springs  and  hand  dug  wells  provided  water   to  these  villages.  Prior  to  European  contact,  it  has   been  estimated  that  there  were  between  3,600   and  10,000  native  people  in  the  region.             CULTURAL  RESOURCES   III-­‐44   The  first  Europeans,  Romero,  Estudillo  and  Pacheco,  traveled  through   the  Coachella  Valley  searching  for  a  route  to  what  is  now  Yuma  in  1823   through  1825.  These  explorations  did  not  yield  settlement,  however,  as   the  conditions  were  harsh.  The  explorers  used  the  trails  that  had  been   established  by  the  native  peoples.     The  first  US  Government  Land  Office  surveys  in  the  area  occurred  in   the  1850s.  At  that  time,  surveyors  identified  four  native  villages  in  and   near  present  day  La  Quinta.  With  the  arrival  of  European  explorers  and   settlers,  the  native  peoples  were  decimated  by  diseases  introduced  to   the  area,  particularly  smallpox,  for  which  they  had  no  immunity.  By  the   early  20th  century,  government  surveyors  could  not  locate  most  of  the   Cahuilla  villages  identified  in  the  1850s.     The  descendants  of  the  Pass  and  Desert  Cahuilla  are  now  associated   with  several  local  reservations,  including  the  Torres  Martinez,  Cabazon   and  Augustine  to  the  east  and  south  of  the  City,  and  the  Agua  Caliente   and  Morongo  to  the  west.     Historic  Context   In  1862,  William  David  Bradshaw  “discovered”  the  Cocomaricopa  Trail,   a  route  that  had  been  established  by  native  peoples,  and  ran  from  the   Agua  Caliente  Village  (at  present  day  Palm  Springs)  to  the  Pima  villages   in  the  area  of  La  Paz,  Arizona.  Renamed  the  Bradshaw  Trail,  it  roughly   followed   the   course   of   present   day   Highway   111   and   became   the   primary  route  between  Los  Angeles  and  the  Colorado  River  and  the   nearby  gold  fields  in  Arizona.       In   the   1870s,   the   completion   of   the   Southern   Pacific   Railroad   line,   including  stations  in  the  Coachella  Valley,  began  an  influx  of  settlers,   and  by  the  1880s,  public  land  was  opened  for  private  land  claims  by  a   series  of  federal  laws.  As  a  result,  a  substantial  farming  community   developed  in  the  Coachella  Valley.  The  early  farms  were  dependent  on   artesian  wells  and  similar  naturally  occurring  water  sources.  A  reliable   and  steady  water  source  was  not  available  in  the  Valley  until  1948,  with   the  completion  of  the  Coachella  Branch  of  the  All-­‐American  Canal.  The   first  land  claims  in  the  La  Quinta  area  occurred  at  the  turn  of  the  20th   century.  By  the  1910s,  a  number  of  ranches  were  operating  in  the  area   of  present  day  La  Quinta,  including  the  Point  Happy  Ranch.     In   the   1920s,   the   tourism   industry   began   to   establish   itself   in   the   region.   The   La   Quinta   Hotel,   built   by   Walter   Morgan,   began   construction   in   1926.   The   resulting   first   class  hotel   and   its   grounds   made  the  hotel  a  favorite  of  Hollywood  stars  in  the  1930s.  Unlike  busy,     CULTURAL  RESOURCES   III-­‐45   bustling  Palm  Springs,  the  La  Quinta  Hotel  was  considered  a  tranquil   getaway  for  the  discriminating  visitor,  and  it  attracted  both  celebrities   and  industrialists.     In   the   1930s,   Harry   Kiener   subdivided   the   Cove   neighborhood  and   marketed  adobe  cottages  as  “weekend  homes,”  marking  the  birth  of   the  first  residential  community  in  the  area  to  later  become  known  as  La   Quinta.  Following  World  War  II,  La  Quinta  and  the  Valley  continued  to   grow,  and  by  1982,  when  the  City  incorporated,  it  had  a  population  of   3,328  people.       Known  Prehistoric  &  Historic  Resources  in  the  City  and  its  Sphere  of   Influence   The  City’s  location  in  and  around  ancient  Lake  Cahuilla  has  resulted  in  a   concentration  of  prehistoric  resources.  As  shown  in  Exhibit  III-­‐4,  about   60%  of  the  City  and  its  Sphere  of  Influence  have  been  surveyed  for   archaeological   resources,   yielding   over   500   recorded   archaeological   sites.  At  the  shoreline  of  ancient  Lake  Cahuilla,  which  is  believed  to   have  occurred  at  42  feet  above  sea  level,  a  concentration  of  pottery,   grinding  stones,  burned  animal  bones  and  other  remains  point  to  a   relatively  dense  population  of  native  peoples.  Sites  within  the  City  have   been  identified  as  being  from  1600  to  2300  years  ago.  Older  sites  have   been  identified  immediately  west  of  the  City  and  its  Sphere,  and  date   to  about  2700  years  ago.     In  addition  to  a  survey  of  historic  sites  by  the  County  of  Riverside  in  the   1980s,   the   City   first   undertook   its   own   survey   in   1996-­‐1997.   The   resulting   inventory   listed   90   properties   of   historic   importance,   primarily  consisting  of  buildings  and  including  a  segment  of  the  original   Coachella   Canal.   The   La   Quinta   Hotel,   its   casitas   and   La   Casa   were   identified   as   eligible  for   listing   on   the   National   Register   of   Historic   Places,   along   with   other   locations   eligible   for   listing   on   the   State   Historic  Register.  The  City’s  survey  also  identified  the  Cove  (bounded   by  Calle  Tampico  on  the  north,  Avenida  Bermudas  on  the  east,  Calle   Tecate  on  the  south  and  Avenida  Montezuma  and  Bear  Creek  on  the   west)  as  a  potential  historic  district  eligible  for  local  designation.  An   update  to  the  City’s  survey  was  conducted  in  2006,  resulting  in  the   addition   of   183   buildings   to   the   California   Historical   Resources   Inventory,  bringing  the  total  to  280.  The  majority  of  these  are  single   family  homes  dating  mostly  to  the  1930s  and  1940s.         CULTURAL  RESOURCES   III-­‐46     THIS  PAGE

The  large  number  of  resources  identified  to  date  in  the  City  and  its   Sphere  confirm  the  area’s  significance  for  Native  American  resources   and  historic  buildings  significant  to  the  area’s  early  development.       Areas   currently   in   agriculture   in   the   Sphere   of   Influence   cannot   be   discounted.  The  relatively  shallow  depth  at  which  agricultural  activities   occur  makes  it  possible  for  buried  resources  to  survive.     City  Programs  Relating  to  Cultural  Resources   The  City  adopted  a  Historic  Preservation  Ordinance  in  1991,  codified  in   Title   7   of   the   Municipal  Code.   The   ordinance   establishes  a   Historic   Preservation  Commission  to  advise  the  City  Council  on  matters  relating   to   archaeological   and  historic   resources,  and   a   historic   resources   inventory   and   designation   procedures.   In   1995,   the   City   became   a   Certified   Local   Government   under   the   State’s   enabling   legislation.   Under  this  program,  the  City  has  established  guidelines  and  standards   regarding  the   qualifications   of   archaeological   consultants,  and   implemented   programs   allowing   for   the   transfer   of   development   rights  and  the  use  of  the  State  Historic  Building  Code.     The  City  also  opened  its  museum,  located  on  Avenida  Montezuma  at   the  base  of  the  Cove.  It  provides  a  repository  for  a  number  of  historic   and  Native  American  resources  found  in  the  City,  as  well  as  exhibits   which  chronicle  the  development  of  La  Quinta  over  the  years.       Paleontological  Context   Paleontological  resources  are  the  fossilized  remains  of  ancient  plants   and  animals.  They  occur  in  older  soils  which  have  been  deposited  in  the   Valley   over   millions   of   years.   About   4   million   years   ago,   the   Salton   Trough,  in  which  the  Coachella  Valley  is  located,  was  part  of  the  Gulf  of   California,  and  extended  as  far  as  the  Painted  Hills,  northeast  of  the   current  City  of  Palm  Springs.  Eventually,  the  Salton  Trough  was  cut  off   from  the  Gulf  of  California  by  the  delta  of  the  Colorado  River.     Ancient  Lake  Cahuilla,  which  occurred  over  a  much  larger  area  than  the   current  Salton  Sea,  resulted  from  flooding  of  the  Colorado  River  and   receded  a  number  of  times.  This  process  left  behind  sediments  which   have  the  potential  to  have  buried  plant  and  animal  remains,  some  of   which  became   fossilized  over   time.   Freshwater   shells  from   the   last   stand  of  the  Lake  in  the  17th  century  are  found  on  the  surface  of  land  in   the  City  and  its  Sphere  of  Influence  today.         CULTURAL  RESOURCES   III-­‐50   In  general,  fossils  occur  in  soils  which  are  at  least  10,000  years  old,   referred  to  as  the  late  Pleistocene  Epoch.  Five  soil  units  have  been   identified  in  the  City  and  its  Sphere,  as  shown  in  Exhibit  III-­‐5.     Mesozoic  Granitic  Rock  occurs  in  the  foothills  on  the  south  and  west   edges   of   the   City.   Granitic   Rock   has   a   low   potential   to   contain   paleontological  resources.     Pleistocene  and  Older  Alluvium  occurs  in  the  southwestern  corner  of   the   City,   at   the   base   of   the   Santa   Rosa   foothills.   Fossils   have   been   found   in   these   soils,   but   not   in   the   City   or   its   Sphere.   The   closest   locality  is  in  the  Indio  Hills,  to  the  northeast  of  the  City.  Pleistocene   soils  have  a  high  potential  to  yield  fossil  remains.     Lake  Cahuilla  Beds  occur  in  areas  where  ancient  Lake  Cahuilla  covered   the  Valley  floor.  Because  of  the  multiple  stands  of  the  ancient  lake,   these  soils  can  occur  in  layers,  intermixed  with  other  soils  which  were   blown  into  the  area  when  the  ancient  lake  was  dry.  Lakebed  sediments   have  yielded  freshwater  diatoms,  plants,  sponges,  mollusks,  and  fish,   as  well  as  small  animals.  Although  the  lakebed  soils  are  much  less  than   10,000  years  old,  they  hold  potentially  significant  information  on  the   area’s   early   ecological   history  and   have   a   high   potential   for   paleontological  resources.     Holocene   Alluvium  occurs  in   the   City’s   Cove   area  and   at   the   southernmost  edges  of  the  City.  These  soils  have  been  brought  into   the  area  by  flooding  in  the  mountains  and  are  too  recent  to  hold  fossil   remains.  They  have  a  low  potential  for  paleontological  resources.     Recent  Dune  Sand  occurs  north  of  Avenue  50  in  the  City.  This  soil  has   been  blown  into  the  area  by  regional  winds  and  recently  deposited.   Dune  Sand  varies  in  depth  and  could  overlay  older  alluvium  at  depth.   Because  of  its  recent  transport  into  the  area,  Dune  Sand  has  a  low   potential  for  paleontological  resources.           CULTURAL  RESOURCES   III-­‐52       PLANNING  FOR  THE  FUTURE   The  City  and  its  Sphere  of  Influence  have  a  rich  and  varied  history.   Many   cultural   resources,  including   prehistoric,   historic  and   paleontological  resources,  have  been  catalogued  in  the  area.  The  City   has   demonstrated   its   commitment   to   its   history   through   the   establishment   of   its   Certified   Local   Government   program   and   the   opening   of   its   museum.   As   development   in   the   City   and   its   Sphere   continues  to  occur,  it  has  the  potential  to  impact  cultural  resources   which  have  not  yet  been  identified.       Further,   as   the   City   grows,   it   must   continue   to   reflect   on   the   importance   of   its   history   and   its   preservation  to   assure   that   these   resources,  which  ultimately  cannot  be  renewed,  are  not  lost  to  future   generations.     GOALS,  POLICIES  AND

PURPOSE   The  Water  Resources  Element  describes  water  supply  management  in   the  region  and  the  City.  It  is  important  to  note  that  the  aquifer  that   supplies  the  City  and  its  Sphere  of  Influence  is  shared  with  the  other   communities  of  the  Coachella  Valley.  In  order  to  assure  that  everyone   in  the  region  has  sufficient  water,  it  is  important  that  La  Quinta,  as  one   of  the  stewards  of  the  local  water  supply,  manages  and  conserves  this   important  resource.     When   describing   water   resources,   this   Element   addresses   both   the   amount  of  water  available  for  use  in  the  City’s  homes  and  businesses   and  the  quality  of  that  water.  Water  supplies  in  the  City  are  managed   by  the  Coachella  Valley  Water  District,  with  which  the  City  has  had  a   long   and   successful   relationship.   The   City’s   goals,   policies   and   programs  relating  to  water  resource  management  are  important  to  the   District’s   continued   ability   to   provide   domestic   water   to   new   and   existing  development  in  the  City  and  the  Sphere  of  Influence.     Government  Code  65302(d)  requires  that  all  General  Plans  include  a   conservation  component  to  assure  the  preservation  of  a  number  of   resources.   This   Water   Resources   Element   addresses   one   of   these   components.  Other  elements  which  relate  to  water  resources  include   the  Biological  Resources,  Land  Use,  Livable  Community,  and  Flooding   and  Hydrology  Elements.     BACKGROUND   Most   domestic   water  –  water   used   in   homes   and   businesses  –  is  pumped  from  an  under-­‐ground  aquifer,   or  series  of  aquifers,  which  occur  below  most  of  the   Coachella   Valley.   The   aquifer   is   not   continuous  –   earthquake   faults,   rock   barriers,  and   other   naturally   occurring   breaks   create   barriers   between  the  sub-­‐basins.         WATER  RESOURCES   III-­‐58   The   Whitewater   River   sub-­‐basin   is   the   Coachella   Valley’s   aquifer.   It   extends  from  Palm  Springs  to  the  Salton  Sea,  and  is  subdivided  into  a   number  of  subareas.  Water  in  the  aquifer  flows  from  the  northwest  to   the  southeast.  The  Lower  Thermal  subarea  occurs  under  the  City  and   its   Sphere   of   Influence,   and   provides   it   with   its   primary   source   of   domestic  water.  The  subarea’s  water  supply  occurs  at  depths  of  300  to   600  feet  below  the  surface,  and  may  extend  to  a  depth  of  1,000  feet.   The   Upper   and   Lower   Thermal   subareas   together   are   estimated   to   contain  19.4  million  acre-­‐feet  of  water  (1  acre-­‐foot  is  equal  to  324,829   gallons).  The  sub-­‐basin  is  illustrated  in  Exhibit  III-­‐6.     The  Coachella  Valley  Water  District  (CVWD)  is  responsible  for  providing   domestic  and  irrigation  water  to  the  City  and  its  Sphere  of  Influence.   All  domestic  water  is  extracted  from  the  aquifer  through  a  system  of   wells,  which  CVWD  operates  throughout  its  District.  In  addition,  CVWD   imports  water  from  the  Colorado  River,  which  is  used  to  recharge  the   aquifer.  There  are  three  recharge  facilities  in  the  Valley:  one  located   northwest   of   Palm   Springs,   one   located   southeast   of   La   Quinta,   in   Martinez  Canyon;  and  one  located  in  La  Quinta,  south  of  Avenue  58,   and  west  of  Madison  Street.     A   detailed   description   of   the   geology   and   capacity   of   the   regional   aquifer  is  included  in  the  General  Plan  Environmental  Impact  Report.     Water  Demand   Continued   growth   in   the   City   and   the   region   has   resulted   in   an   increased   demand   for   domestic   water.   As   a   result,   CVWD   extracts   more   water   from   the   Lower   Thermal   subarea   than   is   naturally   recharged   into   it   every   year  –  a   condition   known   as   overdraft.   The   subarea  has  been  in  overdraft  since  the  1980s,  prompting  CVWD  to   expand   its   recharge   facilities   and   conservation   efforts.   In   2009,   approximately   160,000   acre   feet   of   water   were   pumped   from   the   Lower   Thermal   subarea,   which   represents   a   decrease   in   water   production  over  1999  figures,  which  stood  at  168,300  acre  feet.  CVWD   also  estimates  that  natural  recharge,  groundwater  recharge  programs   and  similar  programs  returned  all  but  23,912  acre  feet  to  the  aquifer  –   resulting   in   an   overdraft   condition.   Although   CVWD   has   steadily   increased  its  recharge  of  the  groundwater  basin  (from  1,813  acre-­‐feet   in  2000  to  21,735  acre-­‐feet  in  2009),  drought  conditions  and  increased   demand  have  made  it  impossible  for  the  District  to  maintain  a  positive   recharge.  CVWD  plans  to  increase  recharge  efforts  as  the  City  and  its   Sphere   of   Influence   continue   to   develop.   However,   increased   development  will  contribute  to  greater  demand  for  water  resources   and  the  potential  for  continued  overdraft.         WATER  RESOURCES   III-­‐60   Water  Conservation   A  more  effective  manner  to  reduce  overdraft  in  the  aquifer  is  through   water  conservation.  The  City  and  CVWD  have  implemented  a  number   of   conservation   programs   in   recent   years   which   have   reduced   consumption   of   domestic   water.   It   is   critical   that   these   programs   continue  and  expand,  as  possible,  through  build  out  of  the  General   Plan.     Domestic  water  used  in  homes  and  businesses  is  sent  to  wastewater   treatment  plants  operated  by  CVWD.  A  portion  of  the  domestic  water   used  for  irrigation  is  returned  to  the  aquifer  when  it  penetrates  the  soil   and  percolates  back  to  its  source.  However,  irrigation  of  landscaping  is   the   largest   consumer   of   water   in   most   homes,   and   has   the   most   inefficient  return  to  the  water  table.  The  reuse  of  water  used  in  homes   for  irrigation  can,  therefore,  be  an  efficient  conservation  method.       CVWD  has  two  wastewater  treatment  plants  serving  the  City,  but  only   the  plant  which  serves  the  area  north  of  Miles  Avenue  currently  has   the  ability  to  generate  tertiary  treated  water  (reclaimed  water  which   can  be  used  for  irrigation,  but  is  not  potable).  That  plant  has  a  capacity   of  2.5  million  gallons  per  day  and  an  expansion  potential  to  7.5  million   gallons  per  day.  In  the  long  term,  the  expansion  of  tertiary  treated   water  facilities  to  serve  irrigation  needs  throughout  the  City  and  its   Sphere  will  be  critical  to  water  conservation  efforts.     The   City   has   also   implemented   water   conservation  measures  in   landscaping  maintenance.  Chapter  8.13  of  the  Municipal  Code,  Water   Efficient   Landscaping,   provides   detailed   requirements   for   water   conservation  in  landscaping  of  new  and  existing  projects.  In  addition,   Building   Code   requirements   provide   for   the   use   of   water-­‐efficient   fixtures  in  new  homes  or  businesses,  or  those  which  are  undergoing   major   remodeling.   These   requirements   extend   to   water   features,   fountains  and  lakes  within  projects,  which  can  be  a  significant  source   of  water  loss,  particularly  due  to  the  evaporation  which  occurs  in  the   City’s  desert  environment.     The  City  has  also  partnered  with  CVWD  in  conservation  programs  and   plans   to   continue   such   programs.   They   have   included   “smart   controllers”   for   landscaping   irrigation   in   the   past,   and   may   include   other  conservation  efforts  as  new  technology  develops.     CVWD  holds  seminars  and  workshops  relating  to  water  conservation   for  homeowners  and  landscape  professionals,  and  offers  rebates  and   discounts  for  the  installation  of  drought  tolerant  landscaping,  water     WATER  RESOURCES   III-­‐61   efficient   sprinklers,   and   smart   controller   systems.   The   District   also   publishes   a   number   of   brochures   on   water   conservation,   which   are   available  to  the  public.     Sustainability  of  Water  Resources   CVWD’s  Urban   Water   Management   Plan   sets   forth   a   number   of   demand   management   measures   intended   to   achieve   water   conservation  goals  and  assure  that  water  supplies  are  managed  for   long-­‐term  use.  As  part  of  the  overall  management  strategy  employed   by  CVWD,  conjunctive  use  management  will  assure  that  water  supplies   are   sustainable.   While   the   District   is   responsible   for   large-­‐scale   groundwater  recharge  efforts,  the  City  of  La  Quinta  recognizes  that   land  use  development  patterns,  lot  coverage,  and  stormwater  runoff   within  the  planning  area  contribute  to  regional  water  conditions.  The   City  has  developed  goals,  policies,  and  programs  that  aim  to  achieve   water   use   efficiency   for   all   applications   (indoor   use   and   irrigation),   support   expansion   of   recycled   water   infrastructure  and   use,   and   prevent   contamination   of   water   supplies   through   the   use   of   best   management  practices  and  control  measures,  such  as  those  specific  to   the   NPDES   and   SWPPP  (see   below).   These   City   efforts,   as   well   as   ongoing   coordination   with   CVWD,   will   facilitate   the   responsible   and   sustainable  use  of  water  resources.     Surface  Water   The  City  is  subject  to  short  duration  rainfall  events  which  can  generate   significant  amounts  of  surface  water.  This  water  source  can  be  used  to   recharge  the  aquifer  through  the  installation  of  stormwater  retention   basins   on   development   projects.   The   City   requires   that   all   projects   contain  and  control  the  rain  water  which  flows  through  a  developed   site,   most   commonly   through   the   installation   of   retention   basins.   These  basins  are  usually  landscaped  and  allow  stormwater  to  percolate   into  the  ground.  Although  stormwater  retention  will  never  represent  a   significant  increase  in  aquifer  recharge  because  of  the  limited  amount   of  rain  which  falls  in  the  City,  it  will  continue  to  provide  some  increase   in  annual  recharge  efforts.     Storm  water  which  travels  over  built  surfaces,  such  as  parking  lots  and   building   rooftops,   has   the   potential   to   be   contaminated   by   oils,   solvents,  and  chemicals.  The  City  implements  the  requirements  of  the   National   Pollution   Discharge   Elimination   System   (NPDES)   to   assure   that   stormwaters   are   protected   from   pollutants.  The   City’s   NPDES   permits  include:  1)  Storm  Water  Pollution  Prevention  Plans  (SWPPP),   and   2)  Water   Quality  Management   Plans   (WQMP),   which  are   engineering  plans  that  must  be  submitted  and  approved  by  the  Public         WATER  RESOURCES   III-­‐62   Works   Department   prior   to   construction.   These   plans   identify   the   specific  measures,  or  Best  Management  Practices,  that  will  be  taken  by   the  developer  to  prevent  storm  water  pollution  before,  during,  and   after  construction.     A   complete   discussion   of   stormwater   and   stormwater   pollution   prevention  is  included  in  the  Flooding  and  Hydrology  Element.     PLANNING  FOR  THE  FUTURE   The  build  out  of  the  City  and  its  Sphere  of  Influence  could  add  more   than   53,000   housing   units   and   almost   13  million   square   feet   of   commercial  and  industrial  space  to  the  area.  All  new  development  will   require  domestic  water  for  interior  use  and  landscaping  irrigation  and   will   increase   the   demand   on   limited   water   resources.   The   City   has   already   implemented   water   conservation   efforts  and   will   need   to   continue  and  expand  these  efforts  to  protect  its  water  resources.     GOALS,  POLICIES  AND  PROGRAMS   GOAL  WR-­‐1     The  efficient  use  and  conservation  of  the  City’s  water

following   goals  and   their   associated   policies   and   programs   are   closely  related  to  those  of  this  Element.     GOAL  UTL-­‐1:  Domestic  water  facilities  and  services  which  adequately   serve  the  existing  and  long-­‐term  needs  of  the  City.     GOAL   FH-­‐1:  Protection   of   the  health,   safety   and   welfare   of   the   community  from  flooding  and  hydrological  hazards.     WATER  RESOURCES   III-­‐65   THIS  PAGE  INTENTIONALLY  LEFT  BLANK         OPEN  SPACE  AND  CONSERVATION   III-­‐67             OPEN  SPACE  AND  CONSERVATION     PURPOSE   Some  of  La  Quinta’s  greatest  assets  are  its  scenic  mountain  vistas  and   wilderness  areas.    The  Open  Space  Element  helps  to  protect  these  and   other   assets   by   designating   policies   and   programs   for   their   management   and   conservation.     These  policies   and   programs   are   designed  to  discourage  the  premature  or  inappropriate  conversion  of   open   space   land  to   more   intense   land   uses.     They   are  intended   to   assure   the   long-­‐term   viability   of   open   space  lands  for  resource   conservation,   public   health   and   safety,   recreation,  and   scenic   enjoyment.     Government  Code  Section  65560(b)  defines  open  space  as  “any  parcel   or  area  of  land  or  water  which  is  essentially  unimproved  and  devoted  to   an   open-­‐space   use.”    These   lands   typically   include   rivers,   streams,   managed  agricultural  lands,  mineral  resources,  parks  and  recreational   lands,  and  lands  dedicated  for  the  preservation  of  biological  or  other   natural  resources.     Government  Code  Section  65302(d)  requires  that  General  Plans  include   elements  which  address  resource  conservation  and  designate  lands  for   preservation.  Government  Code  Section  65566,  also  referred  to  as  the   Open  Space  Lands  Act,  requires  local  governments  to  prepare  open   space  plans  before  adopting  open  space  zoning  ordinances.    This   helps   to   assure   that   open   space   zoning   regulations   are   consistent  with  open  space  plans.           OPEN  SPACE  AND  CONSERVATION   III-­‐68   BACKGROUND   Because  the  Open  Space  Element  addresses  a  broad  range  of  issues,  its   policies  and  programs  are  interwoven  with  many  other  General  Plan   elements,   including  Sustainability,  Land   Use,   Parks   and   Recreation,   Circulation,  Biological   Resources,   and  Environmental   Hazards.    In   addition,  the  Open  Space  Element  complements  the  Coachella  Valley   Multi-­‐Species   Habitat   Conservation   Plan   (MSHCP)   by   providing   protection  for  lands  which  may  be  identified  as  containing  important   wildlife  habitat.     Open  Space  Resources   Undeveloped  open  space  areas  located  along  the  Santa  Rosa  and  San   Jacinto  Mountains  and   their   foothills   constitute  about   half   of   the   valuable   biological,  recreational,   and   scenic   resources   enjoyed   by   residents   and   visitors   in   the   City   of   La   Quinta,   with   the   remainder   generally   consisting   of   the   City’s   storm   water   management   system,   public   and   private   golf   courses,   public   parks,   and   related   areas.   Approximately   19.1  square   miles   of   open   space   land   are  identified   within  the  General  Plan  Land  Use  Map.     !"#$%&"'(#%)'$*%+,#,%-$%)'%./-$0'1%-$%2(3#, 456 476 8696 :'0#3%;%<=>>*"='-$ ?'0/3'=%!"#$%&"'(# @>=A%B>/3,# C'3D,%'$*%E#(3#'0->$   Open  Space  for  the  Preservation  of  Natural  Resources   About  half  of  the  lands  dedicated  for  open  space  in  La  Quinta  have   been  set  aside  for  the  preservation  of  natural  resources.    Most  of  this   area  is  located  within  the  Santa  Rosa  and  San  Jacinto  Conservation   Area,   is   protected   through   a   deed   restriction,   or   has   development   limitations  under  the  MSHCP.    About  84%  of  the  City’s  General  Plan   area   located   within   the   MSHCP   conservation   boundary   is   currently     OPEN  SPACE  AND  CONSERVATION   III-­‐69   designated  as  open  space,  with  the  remainder  identified  as  low  density   residential.8       In  the  southwestern  portion  of  La  Quinta,  the  Coachella  Valley  Multi-­‐ Species  Habitat  Conservation  Plan  (MSHCP)  has  identified  most  of  the   Low  Density  Residential  parcels  located  within  Section  5,  Township  7S,   Range  7E  for  preservation  and  habitat  acquisition.    This  undeveloped   section   of   the   City,   which   contains   the   only   residentially-­‐designated   lands   located   within   the   MSHCP   conservation   boundary,   generally   consists  of  Sonoran  Creosote  Bush  Scrub  and  provides  valuable  habitat   for   special   status   species,  such   as   Burrowing   Owl   and   Peninsular   Bighorn  Sheep,  as  identified  in  the  Biological  Resources  Element.    The   MSHCP  permits  these  lands,  if  not  acquired  by  a  conservation  agency,   to   develop   up   to   10%,   while   the   balance   of   the   parcel   must   be   preserved   in   its   natural   condition.9  Approximately   105   acres   of   land   within   Section   5   has   been  acquired  for   the   preservation  of   natural   resources  by  local  and  state  conservation  agencies.     Open  Space  for  the  Managed  Production  of  Resources   La  Quinta’s  open  space  element  also  designates  lands  for  the  managed   production   of   resources.   The   Sphere   of   Influence   primarily  contains   agricultural  lands  and  has  the  potential  for  additional  properties  to  be   set   aside   in   the   future   for   the   managed   production   of   resources.   Approximately  582  acres  of  land,  all  located  within  the  City’s  Sphere  of   Influence,  have  been  set  aside  for  farmland  conservation  under  the   Williamson   Act   provisions.   Officially  titled  the   California   Land   Conservation  Act  of  1965,  the  Williamson  Act  provides  property  tax   relief  to  owners  of  farmland  and  open-­‐space  land  in  exchange  for  a   ten-­‐year  agreement  that  the  land  will  not  be  developed  or  otherwise   converted  to  another  use.  There  are  no  active  or  permitted  quarries   identified  within  the  General  Plan  area.                                                                                                                                           8  CVMSHCP,  Table  4-­‐110.   9  CVMSHCP  Vol.1  Sec.  4,  p.4-­‐154.         OPEN  SPACE  AND  CONSERVATION   III-­‐70   Open  Space  for  Recreation   The  remaining  areas  in  the  City   generally   consist   of   land   set   aside   for   Recreational   Open   Space,  such  as  City  and  regional   parks  and  golf  courses.    The  City   of   La   Quinta  operates   11   parks   and  shares  two  sports  facilities   with   Desert   Sands   Unified   School   District.     The   City   also   contains  two  regional  parks.  The   6.5   acre   La   Quinta   Community   Park,   located   in   the   Village,   is   managed   by   the   Desert   Recreational   District,   while   the   710  acre  Lake  Cahuilla  Regional   Park,   located   in   the   southern   portion   of   the   City,  is   managed   by   the   Riverside   County   Parks   Department.  In  addition  to  these  larger  parks,  small  “pocket  parks”  are   located  throughout  the  City,  within  individual  subdivisions.     In  addition  to  City  Parks,  the  City  of  La  Quinta  holds  146.7  acres  of  open   space  land   dedicated   for   the   joint   purpose   of   conservation   and   recreation.  These  areas  include  the  27.9  acre  Fred  Wolff  Bear  Creek   Nature  Preserve,  the  114  acre  Cove  Oasis  Trailhead,  and  the  4.75  acre   Bear   Creek   Trail.     These   areas   provide   an   urban   buffer   and   a  trail   connection   between   the   City   and   the   Santa   Rosa   and   San   Jacinto   National  Monument.     As  La  Quinta  is  a  well-­‐known  golfing  destination,  there  are  23  public   and  private  golf  courses  located  within  the  City,  most  of  which  are   located   within   residential   areas.     La   Quinta   has   one   municipal   golf   course,   SilverRock   Resort,   and   another   seven   private   golf   courses   available  for  public  play.    All  golf  courses  are  identified  as  open  space  in   the  General  Plan’s  land  use  map.     Open  Space  for  Public  Health  and  Safety   Due  to  La  Quinta’s  geographical  setting  at  the  foot  of  the  Santa  Rosa   and  San  Jacinto  Mountains,  some  properties  are  undevelopable  due  to   engineering  and  safety  limitations,  or  have  been  designated  for  the   purposes  of  flood  control  and  storm  water  conveyance.        These  lands   have  been  set  aside  as  open  space  dedicated  to  protect  public  health   and  safety.         Table  III-­‐4   La  Quinta  City  and  Regional  Parks   Park Acreage Adams  Park  3.5   Civic  Center  Campus  17.5

  greater   have   been   designated  as  open  space  in  order  to  protect  the  public  from  hazards   associated   with   hillside   development,   including   seismic   activity,   landslides,  flooding,  inaccessibility  for  fire  and  emergency  services,  lack   of  water  for  fire  control,  wildfires,  collapse  of  roads  and  similar  risks.     About  6%  of  the  open  space  lands  designated  within  La  Quinta  have   specifically  been  dedicated  for  purposes  of  flood  control  and  water.     These  areas  are  connected  to  a  regional  conveyance  system  managed   by  the  Coachella  Valley  Water  District,  and  include  the  Coachella  Valley   Stormwater   Channel,   the   La   Quinta   Evacuation   Channel,   the   All-­‐ American   Canal,   the   Upper   Bear   Creek   Drainage   System,   the   Lake   Cahuilla  Reservoir,  and  the  East  La  Quinta  Channel.       PLANNING  FOR  THE  FUTURE   The  General  Plan  land  use  map  is  anticipated  to  result  in  a  potential   build-­‐out   population   of   about  134,352  in   the  City   and   its   sphere   of   influence.    The  General  Plan  accommodates  this  growth  by  identifying   12,193  acres  (19.1  square  miles)  of  total  open  space  lands.  Open  Space   lands   are   divided   into   two   categories   on   the   General  Plan   land   use   map,  Recreational  Open  Space  and  Natural  Open  Space.  Recreational   Open  Space  consists  of  public  parks  and  golf  courses,  while  Natural   Open  Space  consists  of  wilderness  and  natural  resources  and  water   and  flood  control  facilities.     Thoughtful  implementation  of  the  General  Plan,  Zoning  Ordinance  and   other  regulatory  mechanisms  will  be  required  to  assure  the  long-­‐term   preservation   of   open   spaces.  The   City   and   other   conservation   organizations  can  play  an  important  role  in  acquiring  federal  and  state   grants  and  other  funding  mechanisms  for  the  purchase  of  conservation   easements  and/or  fee  simple  land  ownership  interests.    The  City  also   has   the   opportunity   to   encourage   residents   and   other   agencies   to   become   involved   in   open   space   preservation.  On-­‐going   efforts   between   the   City,  Coachella   Valley   Association   of   Governments   (CVAG),   Bureau   of   Land   Management,  National   Forest   Service,   adjoining   communities,  and   private   entities   are   necessary   for   the   continued  conservation  of  local  and  regional  open  space  resources.           OPEN  SPACE  AND  CONSERVATION   III-­‐72   GOALS,  POLICIES  AND  PROGRAMS   GOAL  OS-­‐1     Preservation,  conservation  and  management  of  the
