The building permit is dependent on the plat design, which has not been finalized
or approved at this time; accordingly, this building permit cannot be issued, as

a. Alternatively, full design and construction details of the detention system
could be included and reviewed with the current permit submittal, but this
would likely be a duplication of effort as the detention system would also
need to be reviewed with the plat civils.
Response: Okay. Short Plat civil construction plan approval will be processed concurrently to avoud
duplication.
2. The surface discharge of the perforated pipe is not permissible; reconfigure the
outfall as needed.
a. If discharge to a private system is proposed, the applicant must
demonstrate legal rights to, and adequate capacity and condition of, the
existing system.
Response: Perforated downspout pipe connected to stormwater control tank system/stub provided by
short plat development plan.
b. Given the site constraints, the City will permit the perforated pipe
connection to be placed in-serieslupstream of the detention system
(despite previous City direction).
Response: Okay.
Runoffisurface flows may not be directed across public walkways; revise plans to
collect runoff from driveway surfaces prior to flowing across the sidewalk.
Response: Per discussions with staff, driveway runoff across sidewalk is acceptable. See update
storm water memo with adjusted impervious surfaces per plan revisions.
