Engineering has reviewed the boundary line adjustment plat, and offers the following review comments:
1. Sheet 1: Provide note to indicate steep slopes exist on TMPs (PIDs) 04600-00-00-10800 and 04600-00-00-
10900, as well as steep slopes field -surveyed on 12/23/20 found to be less steep than 25 percent slope.
2. Sheet 2
a. Since separate deeds accompany SWM and public drainage easements, please provide graphic
separation to discriminate variable (or fixed) width storm water management facility easement/s
from public drainage easements (SWM facility pipe outfalls) as shown on system 1 and 2 plan
views, sheet C-907 (Bolder Engineering, 5/18/22, WP02021-000581. best accomplished by:
i. East SWM facility:
1. No new or revised linework, but leader lines with labels that define a portion of
SD20 (51.50% SD21, SD22, and 6.30' (tie) as shared, common to both variable
width SWM facility easement, and public drainage easement. The public
drainage easement at East SWM facility consists of SD7-SD12, together with
line segments common to both SWM and pipe outfall.
2. Revise SD7-SD-12 labels in favor of PD7, PD8, ... PD12 to distinguish public
drainage easement from storm drain easement lines (SWM facility easement),
alternative labels are needed for public drainage easement (SWM pipe outfall).
3. Provide leader line for public drainage easement.
4. Revise sheet 1 tables, as needed.
ii. West SWM facility:
1. No new or revised linework, but provide leader line Aabel to identify a portion
of SD5 (slightly > 20.0') as shared, common to 49.10' SWM facility easement,
and 20' public drainage easement. The public drainage easement at West SWM
facility consists of SD3, SD4, and portions of SD5 and 435.88' Lot 2 boundary
(slightly >20.0').

2. Revise SD3, SD4 labels in favor of PD3, PD4 (or similar) to distinguish public
drainage easement from storm drain easement lines. Alternative label is needed
for public drainage easement (SWM pipe outfall).
3. Provide tie, SD4 to SD5.
4. Revise SWM easement label to 49.10' storm water management facility
easement (hereby dedicated) rather than variable width.
5. Provide leader line /label for public drainage easement at west SWM facility.
6. Revise /create sheet 1 tables, as needed.
b. Provide (show, label, define) SWM facility access easement between SWM system 2 and private
access easement (plat, sheet 3), to provide corridor for future maintenance/replacement.
c. Calculate and label SWM facility easement areas (ft2).
3. Sheet 4
a. Please check PA ties (383.60', 340.61') and 34.00' PA width against 755.43' boundary length.
b. Provide alternate tie to rebar w/cap set to an boundary monument, since 91.2' tie to U.S. Rte. 29
station 2657+31.80 is a design reference not verifiable in the field (not a monument), recommend
tie to monument that may lie = S27°14'53"W, a boundary comer of PID: 046135-00-00-001D0.
