AGENDA NO. 6.k.
ATTACHMENTS: Memo Update to Engineering Guidelines APPROVED BY: LJM
RECOMMENDED ACTION: Motion to adopt an update to the Engineering Guidelines
BACKGROUND
The City of Rosemount’s Engineering Guidelines provide direction to developers, engineering and
builders within Rosemount. The current version was approved in 2008 and with an interim update in 2016
with the adoption of Atlas 14 precipitation data to guide stormwater design within the City of Rosemount.
This update is being provided to ensure continuity since the update of City Code Title 12 – Subdivision
Regulations will remove direction on street and right of way standards. The standards from Title 12 are
incorporated in to the guidelines. These standards are the same as those currently in the subdivision
ordinance and do not change any requirements of developers or builders.
A more comprehensive review and update is currently underway and will completed in early 2021. That
update will be brought to City Council for approval at that time.
RECOMMENDATION
Staff recommends that Council adopt a motion approving the attached update to the Engineering
Guidelines.
