Long before sustainability and green stormwater infrastructure were buzz words, AHBL staked a flag on the emerging landscape of Low Impact Development (LID). We have been pioneering advancements in this field since 1993 and bring unparalleled experience in sustainable policy development and design. Our multidisciplinary firm offers a rare perspective of sustainability from both sides of the table. We have not only authored countless code amendments to encourage or require the use of LID, we have also implemented sustainable design solutions in both public and private projects across the state. In fact, our work is referenced as official guidance in Western Washington’s Phase I and Phase II Municipal Stormwater Permits and California’s statewide NPDES Municipal Stormwater Permit.

As environmental restrictions become more rigorous, our planners, engineers and landscape architects pride themselves on staying abreast of these ever-changing regulations. We strive to achieve our client’s goals within the boundaries of the code requirements by using the right mix of traditional and sustainable design solutions.

Our Expertise Includes:

  • The integration of LID Best Management Practices (BMPs) into local codes and ordinances;
  • Design and engineering of projects using LID BMPs and LEED standards;
  • Community goal setting and strategic planning of sustainable community systems; and
  • Sustainable master site planning.
