Good Evening John,
We were actually onsite and while we were there I took a look at the Filterra inlets in question. All of the inlets shown
on the plan are actually already installed, including the Filterras. The good news is that the manufacturer (Contech)
must have sent some of their old designs already fabricated to be installed, and the throat inlets are indeed the original
values, and not the corrected values. Therefore all of the throat lengths remain the same from the original approved
plan, and this table has not been affected with this revision.
I hope this clears the concern. But if not feel free to ask any questions for clarity.
Thanks!
Ryan

Ryan,
Thanks for note of explanation, and for your patience.
A single follow -up: please share verification that the few on -grade Filterra flanking inlets that were affected still meet the
capture efficiency of the original Filterra inlets. Provide original v. revised capture efficiency comparison.
Thank you.

John,
Thank you for meeting with us last week at our weekly Thursday timeslot. As discussed, I have prepared short responses
to each item that were listed below. Please let me know if you have any further questions prior to Plan Approval.
1. Storm structure A -29 is a manhole added per the manufacturer's request. We originally had 2 Filterra units
connected in series, which the manufacturer informed us could not be done due to the invert depths. Because
of this we rotated the proposed Filterra unit 90 degrees and shifted it to the head of the parking space instead
of the side of the space. The drainage area stayed the same going to the inlet for capture and treatment
purposes.
2. This Wegmans plan shows the correct SWM vault layouts as approved in WP0201500013.
3. There was a construction conflict between the bottom of the lid and the top of the weir in the flow splitter
structure directly upstream of the proposed Sand filter. The entire Sand filter was lowered one (1) foot in order
to provide adequate clearance for water moving over the weir. The drainage area and sizing calculations all
stayed the same for the Sand filter, just the vertical location was lowered by 1 foot.
4. As discussed, the roof drains have revised again since this last submission, so this table no longer applies.
5. As discussed, the Filterra manufacturer (Contech) now only produces the inlet openings in intervals of
4'. Therefore the Filterra sizes remained the same, sized accordingly for the accompanying drainage areas. The
inlet openings were rounded to the nearest 4' interval for construction purposes. I have verified that the few
on -grade Filterra flanking inlets that were affected still meet the capture efficiency of the original Filterra inlets.
Please let me know if you have any other concerns prior to approval.
Thank you!
Ryan

Ryan,
I had hoped to comment on (linked/12 sheet) Bohler Engineering plans titled Final Site Plan Amendment 1, Srh Street
Station — Wegmans last week (link via email, below). Thank you for your patience.
I am writing to request clarification or information required to evaluate revisions or additions to the Approved Wegmans
Final Site Plan, dated 12/13/13. —Ref. Attached.
I especially hope to understand context of WPO- related changes.
Attached letter is directed to Glenn Brooks, the County Engineer. He may be more familiar with WPO- related items. As
soon as possible, please help with the following items listed in Daniel R. Hines letter to Mr. Brooks:
(from Letter — "text" =text from letter)
"Added Storm Structure A29 per manufacture request." Clarify. What is structure A29? (Cannot locate in inlet
computations table, I IG,or Filterra summary table, I IE) What is effect of adding this structure?
2. "Underground Vaults have been revised per the SWMBMP WPO Phase II Amendment I Plan
Approval." Clarify. Where is revision to underground vaults approval recorded? Can you reference WPO
number?
3. "Sand filter 3 revised due to construction conflict." Clarify. Did size or underlying performance or function of
the sand filter change with revision? Was change discussed with Engineering, or with Glenn Brooks?
4. "Roof drain computations revised to reflect new layout." What is effect of revised computations? -brief
narrative. Consider circumstance of 3 (highlight) sections below. Confirm that runoff "Q" exceeds Capacity.

"Filterra table revised per manufacturer request." Clarify. Compare Amendment submittal table (revision) with
Approved Wegmans Final Site Plan design. Has this item been discussed with Engineering? (with Glenn
Brooks)
This information will help prepare a meaningful response, both for Bohler Engineering and Planning Div. Planning
Coordinator, Ms. Yaniglos.
Thanks in advance for your help with this Ryan. You have helped already by removing 54 sheets.
Your response will help correlate Daniel's letter and amendment items with Approved WPO and SWM requirements.
Please feel free to call. I will be out this afternoon, in meetings 1 1A till then.
Tomorrow, you may have a better chance of reaching me.
Also, feel free to email.
Thanks, again
