The Case for Green Infrastructure

Green InfrastructureStormwater poses challenges to urban areas in the form of combined sewer overflows (CSOs) and flooding.  Impervious surfaces such as driveways, sidewalks, streets, parking lots, and rooftops prevent stormwater from naturally soaking into the ground. This water also carries bacteria and other pollutants into nearby bodies of water.  Waterways are especially vulnerable in cities that have combined sewer systems, which discharge a mixture of sewage and stormwater runoff when these systems overwhelm their designated treatment plants. After a waterway has been degraded, it is difficult and expensive to restore it to a healthy condition.  Prevention is the way to go, and urban communities across the country are turning to “Green Infrastructure (GI)” as a cost-effective, environmentally friendly solution to stormwater management.

HAKS Offers Clients Mobile LiDAR

Mobile Lidar2Contributed by Ken Stigner, PLS, PP

In October 2012, after being retired from space flight, the Space Shuttle Endeavour made a crosstown journey from the Los Angeles International Airport to the California Science Center in Exposition Park.  A new technology known as Mobile LiDAR (for light detecting and ranging) was used to identify and map obstructions so that the shuttle could maneuver through city streets and arrive intact.  LiDAR is a remote sensing technology that measures distance by illuminating a target with a laser and analyzing the reflected light to create a detailed map of the landscape.  HAKS has recently added Mobile LiDAR to our land surveying and mapping service portfolio.  Continue Reading…
