What if the solutions to flooding, pollution, and climate resilience were growing right in front of us? In this episode of P is for Parterre, we dive deep into green infrastructure — what it is, why it matters, and how it's shaping communities across New England. Host Liz Cox is joined by Parterre's ecological crew lead Julia Halm and special guest Kelsey Kern, a water resources engineer at Nitsch Engineering. Kelsey shares her winding path from landscape architecture to civil engineering, her work shaping green infrastructure projects across New England, and why she calls herself a "certified stormwater nerd." We cover how green infrastructure differs from traditional gray infrastructure, the challenges of public perception and maintenance, and how homeowners can implement small-scale green infrastructure on their own property — from rain barrels to backyard rain gardens. Plus, Kelsey leaves listeners with two homework questions you won't be able to stop thinking about, and we get a behind-the-scenes look at her legendary Halloween costume contest streak. Guest: Kelsey Kern — Water Resources Engineer at Nitsch Engineering. Kelsey's work sits at the intersection of sustainability, design, and stormwater management. Over the past six years, she has helped shape green infrastructure projects across New England, from developing guidance for the Boston Water and Sewer Commission to advancing community-focused initiatives like Safe Routes to School. She holds degrees in landscape architecture (Kansas State University) and civil engineering, and is a three-time champion of the Nitsch Halloween costume contest. Co-Host: Julia Halm — Ecological Crew Lead at Parterre Garden Services. Julia specializes in green infrastructure maintenance, including rain gardens in Boston and surrounding towns. Her background spans environmental science, water quality testing, and floodplain restoration in Vermont.
