How to Use This Spreadsheet

JULY 31, 2007 Introduction to the Interactive Municipal Storm Water Ordinances Spreadsheet: "Low Impact Development" ("LID"), also known as "Green Infrastructure," is a general term referring to environmentally-friendly development and building practices. With regard to storm water management, LID is much more than just an environmentally-friendly exercise. More and more communites are recognizing that LID is a powerful tool in their efforts to control storm water runoff volume and quality. Simply put, LID is a series of methods used for keeping and using rain where it falls, instead of letting it go into the sewer system, causing overflows. This spreadsheet was created in order to document LID storm water management practices across the United States. While there are a handful of cities that stand out as being at the forefront of Reading the Storm Water Spreadsheet: Cities or counties are listed in the leftmost column, and the information about that city or county follows to the right. Below is an explanation of what to expect in each column. CITY OR COUNTY Combined Sewer System? WATER/ STORM WATER DEPARTMENT ORDINANCE NOTES. HYPERLINKED TO ONLINE COPY OF THE ORDINANCE A brief description of relevant storm water ordinances, with a link to an online copy, if possible. NAME, GREEN TITLE, AND ROOFS ADDRESS OF CONTACT PERSON The name and contact information of someone available to give more in-depth explanations of the municipality's storm water programs. Many cities are turning roofs into gardens in order to absorb storm water. If the city has a significant green roof program, this space will mention it. "GREEN" PAVEMENT RAIN BARRELS/ BIORETENTION DOWNSPOUT DISCONNECTION VEGETATED STORM WATER SWALES/ FEE RAIN GARDENS LAND ACQUISITION OTHER The name of the city or county being examined in that row. If this space is marked "CSS", then this city or county has a combined sewer system. The name of the government body responsible for storm water management, and a link to their webpage. Permeable pavement decreases storm water runoff, and a few cities are implementing it. Rain barrels can be connected to downspouts of residential, commercial, and governmental buildings to detain storm water for use with plumbing or landscaping. Many older residential areas have downspouts that connect directly to the sewer system. Disconnecting these downspouts keeps storm water out of the system. Vegetated swales can be installed along streets to absorb storm water. Rain gardens can be installed on property to absorb rainwater from downspouts. Many localities are beginning to charge a fee for all property owners based on the amount of impervious surface on their property. This raises money for storm water management, and encourages LID. Some cities are buying land to create or preserve greenspace. This allows for "green corridors" for the absorption and retention of storm water. This space is used to explain or link to any program that doesn't fit into one of the other columns. Navigating the Storm Water Spreadsheet. This an interactive spreadsheet that contains web links to municipal storm water ordinances, programs and other useful information. Clicking once on the cell will take you to the linked website. Click and hold on the cell to remain in the spreadsheet. Note 1: You will notice that many of the squares on the Storm Water Spreadsheet are empty. This means either that the locality for that row of the Spreadsheet lacks a program for that column, or the information on that program was not found during the course of our research. Note 2: Many of the links on the Storm Water Spreadsheet are for large PDF documents that may take several minutes to load before appearing. Note 3: The "Addional Resources" worksheet lists several organizations which have significant Storm Water Resources. Many of these organizations do consulting/research/ and ordinance drafting. HELPFUL DEFINITIONS FOR THE STORMWATER SPREADSHEET: BMP Best Management Practice: This is a storm water management method that has been recognized as effective and is recommended. LID BMP A Low Impact Development Best Management Practice: an LID method that has been recognized as effective and is recommended.

This workshop requires a fee of $15.00 for each participant. Cost covers the rain barrel and all supplies. The city initiated a stormwater utility in 1999, but it was struck as being an unconstitutional tax. The city either has implemented, or is currently working to implement, a new stormwater utility. In the signing of the Consent Decree, the City of Atlanta committed to several projects designed to improve water quality in Metro Atlanta and downstream, including the Greenway Acquisition Project. The Greenway Acquisition Project is referenced in the Consent Decree as a Supplemental Environmental Project (SEP). The $25 million Greenway Acquisition Project is to be implemented in the City of Atlanta and fourteen (14) counties in Metro Atlanta through March, 2007. The intent of the Greenway Acquisition Project is to acquire streamside "buffer" areas to protect streamside areas from development and to provide a vegetated filter for surface runoff.

The design of the bioretention area will allow for the collection and treatment of storm water runoff from existing paved areas. All owners of single-family residential, agricultural or vacant and undeveloped properties will be charged a semi-annual rate of $6.50, or $13.00 per year. Nonresidential property owners are charged based on the square footage of hard surface on their property. For example, if a commercial property has three times as much hard surface area as the average residence (12,000 sq. feet or 3 ERUs), its storm water charge would be three times the residential rate per year, or three times $13.00 ($39.00). The Greater Cincinnati Rain Garden Alliance presented a 2-day Technical Training and Workshop on Rain Gardens and infiltration practices. Canton, OH Charlotte/ Mecklenburg Cty., NC See chapter 18-39 and 18-40 for the Stormwater charge, which may be offset by reductions in peak flow and total runoff.

HYPERLINKED TO ONLINE COPY OF THE ORDINANCE NAME, TITLE, AND ADDRESS OF CONTACT PERSON GREEN ROOFS "GREEN" PAVEMENT Chicago, IL Metropolitan Water This new ordinance, which takes effect on January 1, 2008, requires new Reclamation District of developments or redevelopments of a certain size to capture the first half-inch of Greater Chicago runoff from all impervious surfaces (roofs, driveways, sidewalks, and so forth) onsite, instead of allowing it to run into the sewers or nearby waterways. Developers can adopt a variety of techniques—such as green roofs, permeable pavement, rain barrels and cisterns, bioswales or rain gardens—to capture this initial rainfall so that the water will infiltrate and recharge the underground aquifer. For developments that do not directly discharge to waterways or to a separate municipal storm sewer system, the ordinance seeks to achieve a 15 percent reduction in impervious surfaces from existing conditions.---Note: a copy of this ordinance is in Vorys' document folder #646084.

While the new requirements do allow increases in stormwater runoff volumes after development, they require that the rate of release be controlled. Suggested quantity controls include detention basins, parking lot storage, underground tank storage, and even ―green roofs." ―Post-construction quality controls‖ are permanent features to catch small rain events on-site and reduce pollutants. The specific list of these controls in the manual includes: stormwater basins, media filters, vegetated swales and filter strips, and controls for commercial activities.

Rain barrels are for Chicago residents only. Residents are limited to 1 barrel per household (per year). The City actively encourages homeowners to disconnect their downspouts from the sewer system and direct the water instead to their yards or gardens. Public service announcements, community meetings, instructional video tapes, brochures and discounts on materials for downspout disconnection have all been provided to homeowners. The City will continue and expand its efforts to educate citizens on the benefits of disconnecting existing downspouts and on alternative uses of stormwater. Yes. The City is creating a green infrastructure by utilizing unique open spaces to hold water that would normally drain directly into the sewer system. For instance, the City built a new kind of alley in a North Side community as part of a pilot project. The alley, constructed of a rigid grid system and gravel, allows rainwater to soak into the ground-reducing water flow into the sewer system and backyard flooding. Cleveland, OH Columbus, OH Swales are recommended for drainage areas of 1-2 acres. See page 140 of the Manual. Page 9 of 40 JULY 31, 2007 CITY OR COUNTY Combined Sewer System?
