the subdivision plat. The Deed book and page will be added to the final site plan, but not the road plans
(this set of plans) as the road plans will need to be approved prior to the subdivision plat being recorded.
Then, the site plan is approved after these (2) approvals and the recordation of the plat. The recordation in
formation will be added to the final site plan.' (Rev. 2) No revision to Road Plan required, comment relates
to final plat approval.
11. Sheets 7, 8: Multiple driveways serving attached units are proposed to be steeper than 5%. Nate, AST Ca^°"4

[guidance text removed]
To the extent site plan requirements apply to attached units, please note Max. grade for parking spaces is
5%. [18-4.12.15.c.] (Rev. 1) Addressed. Applicant: `As discussed during the engineering meeting, this
comment is removed. Driveways are not required to adhere to the 5% max slope. However, as discussed
in the meeting, the driveway slopes have been adjusted, and there are no driveway slopes steeper than 8%
or 9%.'

`As noted in comment #5, the wall and maintenance easements have been shown on the plan sheets, and
these easements will be put to record with the subdivision plat, prior to the approval of the final site plan.'
(Rev. 2) No revision to Road Plan required. Requirement will be addressed with final subdivision plat.
14. Note: Flow in pipe between structures 6 and 4 is 96.4% of capacity. Recommend a more conservative
design approach in this section of system. (Rev. 1) Addressed.
15. Increase pipe diameter, slope, or both between SWM and Str. 48. Proposed flow (27.22 cfs) is 99.93% of

`UPDATE Oanderson2 7/31/2020 3:27 PM)
Revised Engineering Division ROAD Plan review comments include not -new comments sent with email on
6/23/2020 identified as requesting revision to Berkmar Overlook Road Plan.
Items 2.4. follow a more -detailed review of SUB202000004 that compares existing conditions with
improvements /demolition proposed to occur (near or) on TMP 45-112F:
1. Please ref first /second emails, a./b. below, and provide design remedy to address non -compliant
parking space geometry outlined in these 6/23 emails.
a. First email: June 23, 2020 12:52 PM, with appearance of CV -system memo —Also
attached to (this) email sent to Applicant, 3:28 pm, this date.
b. Second email: 6/23/2020 4:32 PM —this email makes explicit reference to both site and
road plan revisions.
2. Provide recorded (offsite) sight -distance easement across TMP 45-112F so that proposed sight
distance easement is continuous along Berkmar Drive, south of development entrance.
3. Obtain a temporary construction easement to demolish or construct improvements on TMP 45-
112F, as proposed with Road Plan SUB202000004. A right -of -entry (ROE) letter from owner of TMP 45-
112F may suffice.
4. Clearly, accurately depict existing conditions on TMP 45-112F. Please see satellite imagery
