Engineering -John Anderson Comments:
1. C0.0: Revise Stormwater Nutrient Credits Note to reference 0.09 lb./yr. surplus nutrient
credits, consistent with WPO201800078 Amendment #2.
Sheet C0.0 has been updated to reflect 0.09 Ib/yr of surplus nutrient credits to be consistent
with WPO201800078 Amendment #2.
2. C0.0: Please revise Stormwater Nutrient Credits Note to reference WPO201800078
Amendment #2 Sheet C6.0, dated 11-09-2020.
Note on C0.0 has been updated accordingly.
3. C4.0, C5.0: Provide CG-6 along lower edge of pavement of spa access, rather than CG-2.
Curb with gutter is required per 18-4.12.15.g. The lower edge of spa site access
concentrates runoff, which is then conveyed to storm structures inlets 118 and 120.
CG-6 has been provided as noted in these areas. See Sheets C4.0 and C5.0 for updates.
4. Provide CG-6 where curb exists fronting the 3 (typ.) parking and 2 HC parking spaces
(runoff is conveyed to Str. 116). Also, review item 3 above.
CG-6 has been included in front of the HC parking spaces.
5. C5.0: Reinforced turf pavers grading concentrates runoff along east edge of pavers for
-200' over a 5' vert. interval. Engineering recommends consider permanent measure at
lower end of pavers to distribute this east edge concentrated flow. Proposed grading
virtually assures problems at this location, over time, especially during or after less
frequent storm events which will not have time to infiltrate pavers, but will behave
more nearly as runoff from a fully impervious surface, with concentrated runoff along
the east edge likely to cause erosion. A shift in design now may help avoid remediation
effort, later.
A swale has been added to the eastern side of the emergency access road. A Nyloplast inlet
has been provided to collect concentrated runoff from this swale. See structure 136. See
updates on Sheets C5.0, C6.2, C6.3 and C7.1 accordingly.
6. C7.1: Recommend revise 8" dome grate (increase size) to limit 6.593' spread at this
location, given proximity to road and sidewalk. 6.6' spread at this location is, however,
permissible.
Inlet has been changed to 12 inches. Spread is now 5.04 ft.
7. C7.1: Please ensure storm line profiles are consistent with WPO201800078 Amendment
#2, d. 11/09/2020.
Outside of the addition of structure 136 and pipe 135, storm profiles match that of
W PO201800078.
