Stormwater Presentation

DESCRIPTION: Paul Hausler and Carrie Rivette from Progressive Companies are here today to present on various topics relating to stormwater infrastructure and their impacts. BUDGET ACTION REQUIRED: N/A COMMITTEE/COMMISSION REVIEW: N/A LEGAL REVIEW: N/A SAMPLE MOTION: N/A

Stormwater Presentation These days, most lakefront homeowners are aware of how their actions can affect the water quality in their lakes. However, lakes with storm sewer discharges to them are facing additional issues, that can’t be resolved only by lakefront homeowners’ actions. Lakes in more urban areas are dealing with runoff from yards beyond the lakefront and from streets and parking lots. Our presentation is intended to give the City of Saugatuck a quick update on sources of stormwater contaminants and their impacts on lakes and rivers, especially with rainfall frequency and intensity changing. The precipitation information consists of personal anecdotes and those from across the state with a few graphics on anticipated future rainfall conditions. From there, we will discuss green infrastructure/nature-based solutions that can reduce contaminants coming in from stormwater systems that discharge to the Kalamazoo Lake/River. Below is an outline of the presentation. While we can customize this to fit your community’s needs, it is intended that items A through D are a brief refresher. The emphasis is on nature-based solutions. A. Impacts of stormwater on surface water B. Probability for more extreme precipitation events C. Contaminant sources a. Lawn/Driveway Runoff i. Fertilizers ii. Pet and Avian Waste iii. Pesticides iv. Household Chemicals v. Salt b. Streets i. Sediment ii. Oils and Greases iii. Cleaners/Detergents iv. Increased Water Temperature v. Salt c. Outfalls i. Soil Erosion Sediment ii. All of the Above D. Impacts of above contaminants (i) Harmful algal blooms (ii) Biological oxygen demand – anoxic “dead zones” (iii) Loss of biodiversity (iv) Habitat loss E. Nature-based Solutions a. Rain gardens and bioswales b. Natural shorelines and filter strips c. Daylighting outfalls and buffer strips d. Permeable pavement e. Leaching catch basins f. Mechanical filters F. Questions

Carrie Rivette, a Project Manager and Senior Civil Engineer who recently joined Progressive Companies, brings over a decade of specialized experience in stormwater management and green infrastructure. For 12 years, she managed Grand Rapids’ Municipal Separate Storm Sewer System (MS4) permit, playing a vital role in advancing the City’s green infrastructure initiatives. Her work supported significant urban sustainability plans, including the Green Grand Rapids Master Plan Update, the Stormwater Master Plan, and the Vital Streets Plan, and she helped shape the city’s Green Infrastructure Portfolio Standards and Strategic Plan. Carrie’s collaborative efforts connected the City with prominent organizations like Friends of Grand Rapids Parks and Plaster Creek Stewards and saw her serve nearly ten years on the executive committee for the Lower Grand River Organization of Watersheds (LGROW). Among Carrie’s notable projects, the Curb Cut Rain Gardens Initiative (2013– 2023) stands out as a model of sustainable infrastructure. In partnership with Plaster Creek Stewards, she guided the installation of around 150 curb cut rain gardens in the city, an effort that other local municipalities have since adopted. Her leadership in the Daylighting at The Highlands project (2018–2023) also exemplifies her commitment to environmental restoration. Partnering with the Land Conservancy of West Michigan and other stakeholders, she oversaw the removal of 1,500 feet of stormwater pipe to restore 2,000 feet of natural stream, aligning the project with both grant and city requirements. In the Rainy Day Project (2018–2020), Carrie collaborated with WMEAC and the Green Homes Coalition to implement water conservation efforts and green infrastructure assessments in underserved Grand Rapids neighborhoods, achieving a community-wide reduction in water usage. Carrie’s project portfolio reflects her dedication to sustainable, communitydriven solutions and her skill in managing complex partnerships and regulatory requirements. Her extensive experience in green infrastructure development and collaborative project management will enhance Progressive Companies’ approach to water resources and urban sustainability.
