Low Impact Development Workshop

April 9-10, 2015
Low impact development guidelines, incentives, standards, policies and research were addressed during the 2015 Low Impact Development (LID) Workshop in Tucson on April 9 and 10.  Organized by the Pima County Regional Flood Control District’s collaborative LID Working Group, Pima Association of Governments was among the workshop sponsors and planning partners.  Over 120 people attended the two-day workshop, including transportation planners, flood control engineers, landscape designers, stormwater quality regulators, urban forestry experts, academics and water resource managers.

In addition to Presentation (pdf)s on LID history and successes since 2011, the workshop included an interactive poster session, a guided tour highlighting stormwater harvesting features along Scott Avenue and group discussions on the future of LID in the Tucson region. The field experience covered best practices in LID, methods of measuring the economic benefits of LID and strategies for minimizing maintenance issues, among other insights for both public and private sector professionals.

Arid LID Conference

Green Infrastructure and Low Impact Development in Arid Environments

Arid LID is an annual Southwest regional conference for professionals, advocates, educators and academics. Sessions include Green Infrastructure (GI), research, best practices, policy and regulation, and community based approaches including hands-on activities. The emphasis is finding multiple benefits and integrated approaches among various disciplines and sectors in our arid region.

LID/GI reduces water pollution by capturing and purifying rain runoff using green roofs, permeable materials, alternative street and building design, trees and rain gardens. The EPA has found that implementing well-chosen LID practices saves money for developers, property owners, and communities while protecting and restoring water quality. Beyond cost savings, amenities include enhanced property values, improved habitat, natural aesthetics, and improved quality of life. For these reasons, EPA is incorporating LID provisions in state issued stormwater permits (NPDES permits) which are required in large towns in cities.

PAG was among the planning and sponsoring agencies that brought this conference to the Tucson region in 2012. PAG's LID resources relating to the construction industry are located here and information for the general public can be found here. For more information on conference results and proceedings, research and future conferences, click here.

Arizona Statewide MS4 Summit

The Municipal Separate Storm Sewer System Statewide Summit is run by permittees for permittees. This summit creates a space for information sharing and networking for MS4s AZPDES MS4 Coordinators, Public Works Managers, Water Quality Managers, Environmental and Construction Managers and Inspectors, and Consultants involved with SWMP implementation or development.

Pima Association of Governments is one of the founding members of the planning committee for the MS4 Summit in 2013 and our Clean Water Starts With Me outreach campaign has served as one of the sponsors.
