Recommendations

• Due to the health risks involved from extended PM
  exposure, and the detected influence of unpaved
  streets in PM emissions, it seems obvious that
  reducing the paving deficit should be re-assigned
  as a policy with the highest priority.

Recommendations

• Due to the health risks involved from extended PM
  exposure, and the detected influence of unpaved
  streets in PM emissions, it seems obvious that
  reducing the paving deficit should be re-assigned
  as a policy with the highest priority.

• Consideration should also be given to enact
  public policy towards preventing any further
  approval of urban developments without paved
  streets there is no sense in trying to reduce
  the current deficit, if new developments continue
  adding unpaved streets. Low-income housing
  developments constructed by the City with public
  funds, should include paving of streets as part
  of the minimal infrastructure provided (currently
  only electricity, water and sewage are provided).
  

• Along with the previous recommendation, further
  studies should be conducted to rearrange urban
  design of public low-income housing developments
  to obtain optimal densities and minimize roadway
  area, such that pavement could be included
  without increasing the projects construction
  cost per capita.

• Programs on frequent sweeping should be
  encouraged, but this will have notorious
  cost-efficiency only after paving deficit in the
  city is considerably reduced.

• Optimize strategy for urban area PM study
  concentrate on selective silt sampling / no
  traffic field-data needed (use travel model).
