Description

1) A Better Rainy Day - Find Flooding and Funding with Maps

Abstract: Maps will show location of projects that have involved flooding and the projects funding source to explain, how to incorporate stormwater goals into city projects that positively impact stormwater quality and design. This presentation will speak of stormwater projects that have been funded nationally and new ideas. Funding various project types that improve water quality from all directions, can greatly benefit ecosystems and how the environment connects to habitats and animal life. Online links to filters that can identify funding will be reviewed.

2) Cornell Lift Station and Storm Water Quality Retrofitting

Abstract: Water quality of storm water is a concern for many communities within the country. Retrofitting existing storm water systems with natural and/or mechanical treatment is a popular method to meet the State of Utah discharge water quality requirements while utilizing the current storm water infrastructure. However, retrofitting existing systems can be a challenging, complex, and often costly endeavor. The presentation will focus on the Cornell Lift Station Retrofit in Salt Lake City, Utah that is located along the Jordan River. The Jordan River is an impaired Utah water body with low dissolve oxygen and elevated levels of phosphorus. Salt Lake City was interested in a natural retrofit that would remove the phosphorus from the storm water and increase the dissolved oxygen before it entered the Jordan River. We will present on the project development, design, construction, recent water sampling results (if available), and discuss the lessoned learned from the project, both the good and the bad.

3) An Ugly Index for Stormwater Fees

Abstract: Ugly is in the eye of the beholder. For a developer, anything that threatens the bottom line is ugly. For a politician, any fee that threatens reelection is ugly. Residents want no fee or one that is equitable. We chose to emphasize equity because a fee that is not equitable is more likely to be challenged successfully in court. The impervious area (IA) of a parcel is a widely accepted surrogate for stormwater production. IA or hard surface includes building footprints, sidewalks, driveways, and parking lots. Fee systems range from the very simple flat fee, that is, the same fee for every parcel, to the fee used by Arvada, Colorado. Arvada has estimated the IA for every parcel in town and the fee charged for each parcel is proportional to that parcel’s IA. This is as fair as any IA-based fee can be. A flat fee is highly inequitable because a small bungalow with 500 square feet of IA pays the same as a big box store with 1,000,000 square feet. Any index should reflect the difference between a flat fee and an Arvada-style fee. Our index begins with a required income for a given level of service. Then for any fee system, the base fee is set to achieve that income. Our ugly index is the ratio of the base fee for the fee system in question to the corresponding Arvada base fee. An index less than 2 qualifies as beautiful, while one greater than 4 as ugly.
