Model Stormwater Ordinance from Oregon DEQ and guidance for including post-construction elements in TMDL Plans.
Stormwater Management Plan Template (MS Word): This Stormwater Management Plan Template (SWMP Template) was developed through a combined effort of the Oregon Department of Environmental Quality (DEQ), the University of Oregon, the Oregon State Extension Sea Grant Program, the City of Cottage Grove, the City of Creswell, and the City of Eugene. In addition to managing stormwater for flood protection, this SWMP Template incorporates water quality measures to address Total Maximum Daily Load (TMDL) pollutants, especially temperature, bacteria and mercury.
The intended audience is cities with populations between 10,000 and 50,000, not covered by a MS4 permit forStorm Water Phase II Regulations (Append E). Non-MS4 Phase II cities with populations fewer than 10,000 are intended to adopt applicable portions of the template which apply to their stormwater goals.
Water Quality Model Development Code: This guidebook integrates many of the “smart development” inspired code recommendations of the TGM project with recommended code language to achieve water quality objectives. This publication is a companion to the Model Development Code and Users Guide for Small Cities.
Model Development Code for Small Cities: The Model Development Code for Small Cities, 3rd Edition, is a TGM program publication. It is a useful tool for smaller communities around the state that wish to update their development codes in a way that promotes efficient land use and transportation planning. The Model Development Code for Small Cities uses planning techniques and best practices to advance TGM principles by addressing all relevant modes of travel (with special attention to walking, bicycling, and transit), including mixed uses, efficient use of land, vibrant downtowns, and improving the connectivity of the street network.
Communities can use the Model Development Code for Small Cities in its entirety or in part. It is a user-friendly document that is free to download and use. It is available as a PDF and in Microsoft Word. Many of the graphics are editable so that a community may adjust graphic labels to fit their needs.
Low Impact Development: A Practical Guide for Watershed Health (doc), Forthcoming: This guide was created for small cities with limited budgets who need practical information on implementing low impact development to meet their TMDL regulations. Written as a prescriptive stormwater management manual template, it might also be used in a voluntary fashion to identify appropriate practices and implement them in planning, design, construction, and maintenance phases. Please email Maria Cahill if you'd like to take an early look at this or be kept up to date on future trainings.

“Incorporating Green Infrastructure Concepts into Total Maximum Daily Loads (TMDLs)”
“Use of Green Infrastructure and Low Impact Development to manage stormwater can reduce pollutant inputs and help restore and maintain the natural hydrology in a watershed. The purpose of this fact sheet is to summarize how Green Infrastructure/Low Impact Development (GI/LID) practices can be incorporated into Total Maximum Daily Loads (TMDLs), and to show how these concepts have been applied in two recent TMDLs.“
Outreach to the Community. Oregon Environmental Council’s publication ““LID: Protecting Oregon’s waters as we grow” provides a brief overview of why a variety of stakeholders in your community should be interested in promoting LID.
Funding Stormwater Programs: Developed by Priscilla Wolverton for Southern Oregon, but it applies all over Oregon. It considers grants and low interest loans. One program of note is the Clean Water State Revolving Fund. If your jurisdiction is already building a large water-related capital improvement project, then you essentially get free money to implement low impact development projects. In reality, the interest rate will be lowered until the cost of the two projects equals the cost of the project you were goiing to build anyway.
