Mark is the Chief Sustainability Officer for City of Phoenix. Mark and I cover topics like Improving Community Cohesion and also how everyone should do a "Energy Audit" for the personal place of residence. We also chat about his career path and what his day-to-day looks like as a Chief Sustainability Officer. Give the show a listen and remember to thank your local Public Works Professionals.

Misspeak: "Mark double-checked with Streets, and they said they do about 3 miles per day of cool pavement, but he had said it took a week to do the 35 miles"
