Storm Water Management Design Standards

'In 2002, the State of Michigan began to implement the second phase of the Clean Water Act.  This phase - informally called 'Phase II' - requires municipalities and other governmental agencies to regulate both the quantity and quality of stormwater runoff discharging into state waters.  To accomplish this task, the Macomb County Public Works Office (MCPWO) has updated its stormwater standards, the first major revision of the rules since 1967.  Once the new standards are finalized, they will be used to evaluate development proposals that discharge stormwater into County drains. 

Three meetings were held in April to solicit comments from local communities, developers and engineers on the new stormwater engineering standards.  The meetings focused on the incorporation of the new water quality requirements, as well as changes to the existing requirements.

We would like to get your input and opinions about the MCPWO’s new draft standards. We want to know your opinions based on your experience with the modern stormwater management techniques that are included in the MCPWO's new standards.  Please submit comments using the comment form provided on this website by May 16, 2008.

After the comment period has ended, the MCPWO will review all comments voiced at the public meetings and written comments submitted to our office.  After we have considered all the comments and finalized the draft, the new standards will become effective this summer.  They will be available on our website for download, or you can pick up a hard copy at our office.

Projects that have already started the review process in the MCPWO before the effective date will continue to be reviewed under the old standards.  Projects that arrive in our office after the effective date will be reviewed using the new standards.  So, if you have a project in our office now, you won't need to make changes to meet the new standards.

If you have any questions regarding the new stormwater standards, please contact the Engineering Division at 586-469-5910.
