The Sustainable Development Code

  1. 1. Working  Paper     The  Sustainable  Community  Development  Code:     Regulating  a  Sustainable  Urban  Land-­use  Patterns  for  a  Post-­Carbon  World   James  van  Hemert    Introduction   Local  government  land-­‐use  codes  must  be  reformed  if  they  are  to  play  an  important  societal  role  in  achieving  a  sustainable  and  livable  post  carbon  future.  The  United  States  of  America’s  100  largest  metropolitan  regions  include  9,000  cities,  towns,  and  counties.i  They  are  failing  to  sufficiently  change  their  codes  to  advance  the  emerging  paradigm  of  sustainability.ii  Worse,  their  codes  represent  a  significant  barrier  to  achieving  sustainability   Tgoals.  This  chapter  describes  a  comprehensive  framework  for  land-­‐use  code  reform,  an  initiative  of  the  Rocky  Mountain  Land  Use  Institute  of  the  University  of  Denver.  The   AFSustainable  Commuity  Development  Code  is  discussed,  featuring  the  code’s  rationale,  approach,  and  structure,  as  well  as  an  explanation  of  one  of  the  code’s  chapters.   Our  land-­‐use  patterns  and  transportation  networks  have  substantially  contributed   Rto  the  bloated  size  of  our  ecological  footprint,iii  which  weighs  in  at  over  four  times  the  global  average,  which  is  itself  already  1.3  times  the  planet’s  carrying  capacity.iv  The  low   Ddensity  and  limited-­‐use  character  of  our  settlements  is  coupled  with  an  almost  exclusively  automobile-­‐focused  transportation  system,  and,  together,  they  conspire  to  trap  us  in  a  wasteful  mobility  patterns  in  which  each  household  depends  almost  exclusively  on  a  privately  owned  vehicle.  Our  built  environment  represents  68  percent  of  our  total  energy  use,  of  which  buildings  represent  39  percent  and  transportation  represents  29  percent.v  We  use  fossil  fuels  to  generate  85  percent  of  our  energy.     In  the  United  States,  the  rate  of  urban  land  consumption  over  the  past  several  generations  has  exceeded  the  rate  of  population  growth  by  several  times.vi  This  increases    
  2. 2. Working  Paper    the  rapidly  growing  financial  burden  of  maintaining  an  automobile-­‐centered  infrastructurevii  and  increases  our  dependency  on  fossil  fuels  with  all  the  attendant  environmental  costs,  including  carbon  greenhouse  gas  emissions.  The  Association  for  the  Study  of  Peak  Oil  and  Gas  (ASPO)  projects  global  “peak  oil”viii  to  occur  in  2010.ix  If  true,  our  entire  human  settlement  infrastructure  and  its  economic  basis  are  in  grave  danger  of  imminent  collapse.x       Global  warming  induced  climate  change  is  already  threatening  the  viability  of  coastline  settlements,  increasing  drought  in  the  Rocky  Mountain  West,  increasing  the  potential  for  disease,  increasing  flooding,  and  threatening  the  viability  of  agricultural   Tproduction.xi  Biologists  predict  that  the  current  alarming  rate  of  species  extinction  will   AFaccelerate  further  under  the  combined  effects  of  climate  change,  declining  habitat  due  to  deforestation,  agriculture,  and  urbanization.xii     Our  current  and  future  land-­‐use  patterns  are  substantially  locked  in  place  by  local   Rgrowth-­‐management  policies  and  development  codes  which,  despite  using  “smart  growth”  labels,  severely  limit  land-­‐use  choices  and  density,  creating  in  effect,  legally  mandated  low-­‐ Ddensity  sprawl.  xiii     Breaking  free  from  this  balkanized  local  land-­‐use  code  regulatory  trap  will  be  excruciatingly  difficult  for  psychological,  social,  political,  and  financial  reasons.  Exacerbating  the  challenge  is  the  fact  that  our  attention  is  distracted  by  narrowly  conceived  technical  fixes  for  addressing  climate  change  and  “peak  oil.”  These  fixes  include,  for  example,  plug-­‐in-­‐hybrid  cars,  that  will  still  require  fossil-­‐fuel  based  electricity.xiv  Most  biofuels  have  yet  to  achieve  a  net  positive  return  on  energy  inputs  and  represent  direct  competition  with  global  food  supplies.xv  Deceptively  named  “clean  coal,”  requiring  carbon    
  3. 3. Working  Paper    sequestration,  remains  uneconomical  and  faces  enormous  technological  challenges.xvi  A  hydrogen  economy  may  be  a  very  long  ways  off.xvii  “Green”  buildings  are  not  necessarily  energy  and  carbon  efficient.xviii  These  fixes  fail  to  address  the  fundamental  problem  of  unsustainable  land-­‐use  patterns,  inflexible  land-­‐use  regulatory  regimes  and  an  exceedingly  burdensome  and  dysfunctional  automobile-­‐focused  roadway  network.  Additionally,  local  politics,  often  excessively  influenced  by  NIMBYs—“not  in  my  back  yard”  activists),  whose  ranks  include  “no  growth”  environmentalists—exacerbates  the  difficulties  already  inherent  in  meeting  the  challenge  of  a  more  sustainable  future.xix       The  critical  and  necessary  starting  point  to  break  free  of  this  regulatory  leg-­‐hold  is   Tcomprehensive  reform  of  land-­‐use  codes  focused  on  the  environmental,  the  economic  and   AFthe  social  equity  elements  of  sustainability  as  the  central  paradigm.      Land-­use  code  family  tree   R Understanding  the  nature  of  our  current  land-­‐use  code  types,  their  history,  and  their  strengths  and  shortcomings  is  a  necessary  first  step.  We  will  be  building  upon  and   Dreforming  these  edifices:  they  are  not  about  to  be  disassembled.  There  are  basically  four  typological  strains  of  land-­‐use  codes  in  operation:  Euclidian,  Planned  Development,  Performance,  and  Form  Based  (as  well  hybrid  codes  that  combine  some  aspects  of  each);  each  of  the  four  primary  types  are  explained  below  in  more  detail.  Most  communities  have  evolved  over  the  years  a  hybridized  form  of  zoning  that  incorporates  elements  to  varying  degrees  of  these  four  types.  An  emerging  fifth  type  of  code  is  the  sustainable  code.      1.  Euclidian    
  4. 4. Working  Paper    In  1926  the  U.S.  Supreme  Court  in  “Village  of  Euclid  vs.  Ambler  Realty  Companyxx”  upheld  the  validity  of  an  ordinance  to  separate  land  uses  into  zone  districts,  specifying  permitted  and  excluded  uses,  prescribing  minimum  lot,  area,  and  bulk  requirement  for  all  permitted  uses.  Land  uses  are  separated  and  sorted  into  groups  based  upon  their  perceived  compatibility  in  order  to  promote  public  “health,  safety,  and  welfare.”  Euclidian  zoning,  also  referred  to  as  “conventional  zoning,”  remains  the  default  base  code  in  most  cities,  towns,  and  counties.    Euclidian  codes  have  not  been  shown  to  be  particularly  effective,  however,  in  dealing  with  myriad  environmental  issues  such  as  floodplain  management  and  habitat  protection.  Their  focus  on  density  maximums  and  the  separation  of  uses  have  the   Tparticularly  pernicious  effect  of  enabling  NIMBY  groups  to  prevent  sustainable  compact   AFand  mixed-­‐use  urban  development.    2.  Planned  Unit  Development  (PUD)     RPlanned  Unit  Development  is  a  means  of  land  regulation  typically  associated  with  large-­‐-­‐scale,  unified  land  development.  Generally  it  promotes  a  mixture  of  land  uses  and  dwelling   Dtypes,  increased  administrative  discretion  of  local  professional  planning  staff,  and  the  enhancement  of  the  bargaining  process  between  the  developer  and  government  municipalities.  This  strengthens  the  municipality’s  site  plan  review  and  control  over  development.  PUDs  exhibit  a  much  greater  degree  of  flexibility  granted  relative  to  the  more  rigid  Euclidian  zoning  scheme.  Although  PUDs  can  address  sustainability  issues,  their  highly  negotiated  and  custom-­‐designed  character  means  that  critical  sustainability  matters  are  often  inadequate  or  left  unaddressed.        
  5. 5. Working  Paper    3.  Performance  Systems    Developed  in  the  1970s  in  response  to  the  overly  rigid  and  often  environmentally  damaging  Euclidian  zoning  system,  performance-­‐based  zoning  takes  as  its  starting  point  an  environmental  carrying  capacity  model  whereby  the  type  and  level  of  development  must  fit  the  unique  characteristics  of  the  individual  property.  Lane  Kendig’s  extensive  work  on  this  system  has  made  his  name  virtually  synonymous  with  it.xxi  Essentially,  the  code  allows  almost  anything  to  be  built  anywhere,  provided  appropriate  mitigation  measures  are  taken  into  consideration.  The  approach  placed  an  emphasis  on  environmental  protection  hitherto  not  present  in  any  Euclidian  scheme.     T   AF4.  Form-­Based  Form-­‐based  development  codes,  popularly  represented  by  the  SmartCode,xxii  focus  heavily  on  the  public  realm  and  the  type  of  urban  form  necessary  to  create  welcoming  public   Rspaces  and  walkable  neighborhoods.  It  is  based  on  an  urban-­‐to-­‐rural  transect  urban  planning  which  defines  a  series  of  zones  that  transition  from  sparse  rural  lands  to  the   Ddense  urban  core.  The  transect  is  an  important  part  of  the  New  Urbanist  and  Smart  Growth  movements.  The  code  is  highly  prescriptive  regarding  urban  form  and  has  limited  explicit  focus  on  environmental  and  natural  resources.  To  the  extent  that  many  New  Urbanist  developments  rely  heavily  on  automobile  transport  and  serve  the  detached  single-­‐family  housing  market,  they  often  fall  short  of  being  truly  sustainable.  Furthermore,  form-­‐based  codes  and  the  SmartCode  in  particular  are  incomplete  and  no  community  can  adopt  them  as  a  stand-­‐alone  regulatory  ordinance.      
  6. 6. Working  Paper    The  Sustainable  Community  Development  Code   The  Sustainable  Community  Development  Code  is  a  holistic  framework  for  local  government  regulation  of  land  use  and  the  environment.  Its  core  distinguishing  feature  is  the  promotion,  enhancement,  and  enforcement  of  environmental,  social,  and  economic  sustainability.  The  meta-­‐goal  of  the  code  is  to  reform  land-­‐use  codes  in  such  a  way  that  human  settlements  move  toward  smaller  ecological  footprints.  This  can  be  measured,  for  example,  in  movement  toward  zero  carbon  emissions,  zero  waste,  zero  fossil  fuel  consumption,  improved  prosperity,  and  greater  social  cohesion.       When  we  began  shaping  the  sustainable  community  development  code,  we  were   Tinfluenced  by  the  work  of  Peter  Brandon  (University  of  Salford,  UK)  and  Patrizia  Lombardi   AF(University  of  Turin,  Italy)  as  expressed  in  “Evaluating  Sustainable  Development  in  the  Built  Environment.”xxiii  Their  work  is  heavily  influenced  by  the  Dutch  philosopher  Herman  Dooyeweerd,  whose  once  obscure  writings  have  gained  currency  recently  in  legal  and   Rplanning  literature.    Dooyeweerd  developed  the  concept  of  modalities,  an  integrated  and  holistic  philosophy  that  can  be  used  to  explain  the  interdependence  between  aspects  of  the   Durban  environment.  This  concept  can  also  be  linked  to  the  wider  sustainable  development  agenda.  The  holism  of  modalities  allows  an  integrated  view  of  the  issue  and  assists  in  explaining  what  is  meant  by,  and  what  contributes  to,  sustainable  development.xxiv       This  overview  covers  the  code’s  distinct  characteristics,  describes  the  intellectual  genesis  of  its  topical  substance,  lists  the  topics  organized  by  major  themes  and  explains  one  of  the  code  chapters  to  describe  the  code’s  operational  features.       The  code’s  distinct  characteristics  include  the  following:   1. A  high  degree  of  comprehensiveness;    
  7. 7. Working  Paper     2. The  integration  of  natural  and  man-­‐made  systems;   3. A  progressive  nature,  drawing  upon  useful  features  of  other  code  frameworks   already  proven  and  in  use:   4. It  is  based  on  sustainable  comprehensive  policy  plans  and  long-­‐term  civic   engagement;  and     5. It  is  tailored  to  local  and  regional  climate,  ecology,  and  culture.  Innovative  operational  features  include  a  user-­‐friendly  web-­‐based  framework,  the  use  of  hyperlinks  to  references  and  government  web  sites,  commentary,  and  sustainability  measurements.  A  key  organizational  feature  is  the  division  of  topics  into  three  categories:   Tovercoming  obstacles,  applying  incentives  and  enacting  regulations.     AF  Major  topics  of  the  code  are  organized  according  to  the  following:  1. ENVIRONMENTAL  HEALTH  AND  NATURAL  RESOURCES   R 1.1. Climate  change   1.2. Low  impact  development  and  green  infrastructure     D 1.3. Natural   resource   conservation—including   wildlife   habitat   and   sensitive   lands   protection     1.4. Water  conservation   1.5. Solid  waste  and  recycling  2. NATURAL  HAZARDS     2.1.

Lighting    Illustration  of  a  code  chapter:  Food  production  and  security   T The  topic  of  food  production  and  security  is  a  salient  illustration  of  the  code  because   AFof  the  significant  impact  it  has  on  our  carbon  emissions.  Food  production  and  security  touch  upon  other  elements  of  sustainability  such  as  human  health,  social  equity,  and  a  healthy  local  economy.  With  the  average  morsel  of  food  on  our  dinner  plates  coming  from   R1500  miles  away,  the  food  system  is  as  sprawling  and  dependent  on  fossil  fuel  as  our  cities.xxv   D    
  10. 10. Working  Paper    Commentary,  Key  statistics,  Goals,   The  chapter,  “Food  production  and  security,”  succinctly  lays  out  the  key  issues  and  rationale  for  inclusion  of  the  topic  in  local  community  development  codes.    The  American  food  system,  which,  broadly  defined,  is  the  sequence  of  activities  linking  food  production,  processing,  distribution  and  access,  consumption,  and  waste  management,  as  well  as  all  the  associated  supporting  and  regulatory  institutions  and  activities.xxvi    In  2000,  approximately  10%  of  all  energy  used  in  the  U.S.  was  consumed  by  the  food  industry.xxvii  Agricultural  activities  were  responsible  for  7%  of  total  U.S.  greenhouse  gas  emissions  in  2005,  of  which  livestock  is  a  major  contributor.xxviii    Goals,  which  can  be  included  in  a  code’s  purpose   Tstatement,  are  suggested  and  include:     AF 1)  The  elimination  of  barriers  such  as  restrictions  on  farmers  markets,  animal   husbandry  and  overly  simplistic  rural  agricultural  zoning  provisions;   2)  Incentives  to  encourage  urban  agriculture  and  increase  access  to  healthy  food;   R and    3)  The  enactment  of  standards  for  sustainable  large  scale  food  production,  access  to   D healthy  foods,  and  limits  on  unhealthy  food  choices  such  as  fast  food  restaurants,   the  expansion  of  permissive  animal  unit  regulations,  and  the  broadening  of     permitted  uses  by  right  in  agricultural  zones.    Within  this  framework  of  goals  local  development  codes  can  play  a  significant  role  in  enhancing  more  energy  efficient  food  production,  increasing  access  to  healthy  foods,  and  supporting  a  local  agricultural  economy.      
  11. 11. Working  Paper    Measurement  index  Suggested  specific  sustainable  measurement  metrics  include:   1. Energy  consumption  to  food  production  ratio;     2. Average  distance  a  food  item  travels  (the  lower,  the  better);   3. Percentage  of  community  demand  met  from  agriculture  within  the  community;   4. Average  distance  to  healthy  food  (absence  of  food  deserts);  and   5. Energy  consumption  to  food  production  ratio.    The  matrix   T The  heart  of  the  code  is  the  matrix  of  regulations,  levels  of  achievement,  references   AFand  commentary,  and  existing  code  examples  from  communities  around  the  USA  and  the  world.  Along  the  x-­‐axis  are  categories  of  achievement  ranging  from  good  (bronze),  better  (silver)  to  best  (gold).    The  remaining  columns  on  this  axis  include  commentary  with   Rreferences  and  exemplary  codes  with  hyperlinks.  The  y-­‐axis  rows  are  organized  according  to  overcoming  barriers,  creating  incentives,  and  enacting  standards.   DFor  this  particular  chapter,  the  matrix  is  further  organized  in  accordance  with  three  broad  categories:  large  scale  commercial  agriculture,  small  scale  urban  agriculture,  and  access  to  healthy  foods.  Table  1  illustrates  the  matrix  in  a  condensed  form.  The  full  chapter  and  matrix  may  be  viewed  at  the  Rocky  Mountain  Land  Use’s  web  site.xxix  It  contains  hyperlinks  to  the  majority  of  references  and  local  development  code  examples
