December 27, 2018 comment - Please submit a stormwater report consistent with the
2012/14 Stormwater Manual and the city's Stormwater Addendum. Please include full
infiltration calculations (see Appendix B of the Addendum to determine the specific
testing requirements). Ensure the stormwater management design for the proposed single
family lot is reflective of the eve line of the house, driveway, and any patios, walkways,
etc. Show a stormwater mitigation system on the plans based on the infiltration rate and
the infeasibility checklists. If there will be an outfall, show what it connects to and where.
Plans show connection to a catch basin that is not on the city system. Please show the
catch basin as proposed. Provide approximate invert elevations for all points of connection
as well as length and size of pipe, including the City storm system inverts if applicable.
Thank you.
