2016 National Association of Counties Award

STORM is proud to announce that Maricopa County Environmental Services Department has earned the 2016 National Association of Counties award for its School Outreach Program. Since 2012, the MC Environmental Services Department has been re-working their outreach program. In 2014, they incorporated a mascot, Sam the Salamander, a slogan, Make Clean Storm Drains Happen, and a multi-grade educational lesson program to ramp up the school age stormwater education. The program outperformed permit requirements for classroom training, and owes some of its success to alignment with the Arizona Science State Standard, which was achieved by seamlessly meshing stormwater lessens with grade specific school curriculums. This approach has created a unique learning atmosphere for k-8 students. Program success has been measured by the rise in teacher class requests and the surge of school age children trained.

Clear Protection for Clean Water

Today, in an historic step for the protection of clean water, EPA and the U.S. Army finalized a rule under the Clean Water Act to more clearly protect the streams and wetlands that form the foundation of the nation’s water resources.

Clean water and water ecology are topics of special interest to many environmental educators. Students of all ages understand the importance of clean water in their own lives. Local watersheds provide opportunities to connect students to nature.

Flash Flooding

Many of you may be aware of the flash flooding that hit US89A between Marble Canyon and House Rock Valley on August 9th. The rain total was between 1.3 and 1.7 inches in 15-20 minutes and is an estimated 200 year event. The really large (trailer-size) boulders in some of the photos were washed down to the culverts from House Rock Valley which is about 1.5 miles upstream. Some of these were actually pushed up onto the road surface when they met the culverts.
