The fourth edition of the Engineering Standards Manual was adopted on March 9, 2009. The fifth edition is here on the City’s website and is available for review and comment until January 29, 2016 at 12 p.m.
It is anticipated that a resolution will be brought to City Council on March 14, adopting the new manual. Provided adoption occurs at that time, either edition may be used during a transition period from March 14-June 1. After June 1, the fourth edition will no longer be in force.
Among the important changes to the ESM are: minimum pipe standards for both sanitary and stormwater applications; maximum pipe depth for sanitary applications; wastewater lift station design; 100-year freeboard and storm duration; tailwater calculations for storm sewer design; floodplain compensating storage vertical limits and connectivity to floodplain; requirements and eligibility for mass grading permits; the ability to direct-pay for testing services; pavement design and elimination of minimum pavement thicknesses; and streamlined surveying and platting requirements.
