Dear Mr. Boyd:
This letter is to address the review comments made by the Engineer Department on March 1,
2018. The numbers of the responses correspond to the comments on the review. I will attempt
to point out how and where the comments have been addressed on the attached revised plans
and reports.
TESC
4) The title of the SWPP section needs to be updated to "The Construction SWPPP 13
Elements".
The title of the SWPP section has been revised.
DRAINAGE AND SITE DEVELOPMENT PLAN
11) The overflow elevation is higher than the footing drain elevation. Footing drains will
flood before groundwater exits the footing drywell via overflow. Please revise the
overflow elevation. Ensure there is 1' of cover for the overflow pipe. Current there is no
cover provided.
Drywell has been deleted. Footing drain will be discharged to the existing ditch at the
front of the property.
12) Revise note 2 to indicate maximum slope of 20%. If pipe slope exceeds 20%, pipe
anchors will be required.
Note 2 has been revised
COMBINED UTILITY PLAN
13) Please relocate the water service as there is less than F of horizontal clearance from
the stormwater system (infiltration trench and roof drain line).
The water service has been relocated.
14) Please show the entire stormwater system faded back on the combined utility plan.
Add a note that a minimum of 18" of vertical clearance is required between sewer and
stormwater lines at crossings.
Comment has been addressed. Note (#11) has been added.
Thank you for your time and effort in this review. If you have any questions or need additional
information, please do not hesitate to call.
