The Jordan Rules went into effect on Aug. 11, 2009. Since that date, there have been many milestone steps toward rule implementation.

Nutrient Loading Accounting Tool

The Jordan Rules require that the Division develop a Nutrient Load Accounting Tool to estimate nutrient loads from new development and changes in loads due to use of Stormwater Control Measures.  The Jordan/Falls Lake Stormwater Nutrient Load Accounting Tool version 2.0 has been recently replaced by a greatly improved version of the Tool known as the Stormwater Nutrient and Phosphorus Tool, or SNAP (version 4.0).  The new tool and accompanying User’s Manual can be downloaded from the NPS Nutrient Practices and Crediting page

You may continue to use version 2.0 of the Tool until January 1, 2018.  At that time, results calculated using version 2.0 will no longer be accepted by local permitting programs or the Division for meeting nutrient export calculations.

New Development Model Program

The Jordan Rules required the division to create a New Development Model Program for use by local governments. The Environmental Management Commission (EMC) approved the model program on March 10, 2011. Local governments were required to develop and submit their programs by Sept. 10, 2011. 

New Development Local Programs

Local governments in the Jordan watershed submitted New Development programs that were approved by the EMC on May 10, 2012.  Session Laws have delayed certain rules. Please contact the local government to see if they are implementing their program.  County ProgramsMunicipality Programs.

Stage One Adaptive Management Program Annual Reports

Local governments are required to submit Annual Reports to the Division's Planning Branch staff by Oct. 31 of each year.  Please use the updated 2018 form.

Please submit the form as a Word document so it can be imported into a database. (Please don't submit a pdf.) Guidance about Stage One programs can be found here.

Stage Two Adaptive Management Program

Based on ongoing monitoring of the lake, local governments may be required to develop Stage Two Programs to reduce nutrient loading from existing developed lands. DWR has developed a draft Model Program.

Jordan Model Buffer Ordinance. In accordance with the rules, governments in the watershed developed local buffer programs and submitted them for approval by the Environmental Management Commission in September 2010, with local implementation beginning two months later. To assist in the development of these programs, the Division of Water Resources provided a model ordinance for use by the local governments.
