Although not entirely clear to staff, it appears that all of the proposed streets within the development are public streets. The City typically requires 80 -foot right-of-way for collector streets and 60 -foot right -of way for new local streets. However, the right-of-way and street widths will need to be reviewed in detail with a preliminary plat.

Ponding for water quality and rate control will be required on site and must be compliant with City standards.
