Re: Detention Pond Certification for Plymouth Church Renovation
JR Project 39322.22
Dear Mr. Barber,�a)e�ZTC'O
The purpose of this letter is to serve as a Detention Pond and Drainage Certification for the
Plymouth Church Renovation project. JR Engineering has reviewed the following items
through field observations and a survey completed March 13, 2008 by our crews:
o Detention pond volumes/Water Quality Outlet Structures
o Flowline Elevations
o Erosion control measures
The detention/water quality ponds and respective outlet structures were surveyed by JR
Engineering after completion in early December. Regrading was required at that point and
another survey was completed on March 13, 2008 by our crews. The results of this survey
indicate that the East Pond Provides 0.042 acre-feet of Water Quality Volume at anelevation
of 5024.32 which is less than the required 0.046 acre-feet as required in the Drainage Report.
The East Pond provides the required 0.262 Acre-ft of detention storage at the 100-yr WSEL
of 5026.25 with a freeboard of 0.04'. The total detention of the East Pond is 0.271 acre-feet at
the overflow elevation of 5026.29'. East Pond shows a positive drainage towards the outlet
sttuctufR It shall be noted that Northern Engineering requested a variance to allow 0.193
acre-feet of the Water Quality Volume to be included in the total detention and a variance
requesting that the 1' freeboard requirement be waived for the site.
The survey also indicates that the West Pond provides 0.015 Ac-ft of Water Quality Volume,
which is less than the required 0.018 Ac-ft required by the DI- inage Report. The West Pond
has a total detention volume of 0.0951 acre-feet_ with a freeboard of 0.02' at the 100-yr WSEL
of 5026.20 which. is greater than the required detention volume of 0.0910 acre-feet as per the
Drainage Report. The total detention of the West Pond is 0.122 acre-feet at the overflow
elevation of '5026.22. West Pond shows a positive drainage towards the outlet structure. None
of the West Pond Water Quality Volume was added to the detention volume.
Detention volumes were adequate as shown above. The Water Quality Volumes were low
despite the fact that the ponds were constructed almost exactly to plan. A calculation check
was completed using the proposed contours provided by Northern Engineering. It was found
that even though the Drainage Report requires 0.046 acre-feet of Water Quality Volume for

970A91-9888 • Fax: 970A91-9984 • wJrengineering.wm
Mr. Jay Barber, March 17, 2008
Page 2 of 3
the East Pond and 0.018 acre-feet for the West Pond, the proposed contours provided by
Northern Engineering did not provide this volume. The design checks show that the proposed
condition as per the contours provided by Northern Engineering propose a Water Quality
Volume of 0.0432 acre-feet for the East Pond and 0.0137 acre-feet for the West Pond. This is
0.0071 acre-feet short of the requirement set forth in the Drainage Report. The Contractor
built the two proposed ponds within 0.18% of the proposed contours with a Water Quality
Volume of 0.0416 acre-feet in the East Pond and 0.0152 acre-feet in the West Pond. The As -
Built condition is 0.0072 acre-feet short of the required water quality volume as per the
Drainage Report.
The water quality outlet structures are in general conformance with the approved plans. The
water quality plate for West Pond and East Pond have the correct number and size of holes at
the correct elevation to provide the volume as shown by the contours on the approved plans.
The 100-yr detention volumes are met for the two ponds and therefore there are no negative
impacts to the safety downstream of the project. It is noted that the shortage of Water Quality
Volume is negligible and has no detrimental impacts downstream and we recommend that the
ponds be certified as is.
Enclosed with this letter you will find as -built stage -storage calculations for West Pond and
East Pond. The required water quality capture volumes (WQCV) and 100-year detention
volumes were obtained from the `'Final Drainage Report for Plymouth Church" (Northern
Engineering March 12, 2007).
As-builts of West Pond and East Pond have been attached. It should also be noted that the
elevations for West Pond and East Pond might change subsequent to the date of the surveys
due to natural and/or artificial actions, reseeding and landscaping. It is expected that these
changes should be minimal.
A survey was also completed obtaining spot elevations for curb and gutter flowlines to verify
that the drainage intent of the approved plans was maintained. The spot elevations have been
hand written on the approved plan included as an attachment to this letter. All elevations are
flowline elevations unless otherwise noted. Overall, the site maintained the intent of the
approved plan with the exceptions marked on the plan and listed below. It is recommended
that these areas be addressed.
1) The proposed condition shows that the water should follow the curb and gutter to the
north-west, but the as -built condition has a high point causing the water to flow across
the asphalt to the north-east towards the parking island.
2) A low -point is causing the water to pond at this location.
3) A low point is causing the water to gather at this point and flow west along the
asphalt.
4) A low point is causing the water to pond in this location.
5) A low point is causing the water to pond in this location.
6) It is recommended that the area beyond the drainage pan be filled in to prevent erosion
and undermining.

JR also observed that temporary erosion control measures such as silt fence and inlet
protection were in place at the time of our field visit in early December, but no erosion control
measures were present at the time of our field visit in March. The mulch and reseeding
process was in progress during the time of the site visit in early December.
Based upon our field visits and provided survey information, it is our opinion that the
drainage facilities as noted above for Plymouth Church Renovation have been constructed -in
general conformance to the approved plans with the exceptions listed herein.

Re: Detention Pond Certification for Plymouth Church
JR Project 39322.22
Dear Mr. Lamarque,
J•R ENGINEERING
A Westrian Company
The purpose of this letter is to. serve as a Detention Pond Certification for the Plymouth
Church project. JR Engineering has reviewed the following items through field observations
and a survey completed November 26, 2007 by our crews:
o Detention pond volumes
o Trickle channel size and slopes
o Erosion control measures
The detention/water - quality ponds and respective outlet structures were surveyed by JR
Engineering after completion. The results of this survey indicate that the East Pond Provides
0.041 Ac-ft of Water Quality Volume which is less than the required 0.046 Ac-ft. The East
Pond provides more than the required 0.289 Acre-ft of total storage with a total of 0.298 Ac-ft
and shows that the detention volume for the 100-Year storm is 0.289 Ac-ft at an elevation of
5026.25' with 0.04' of freeboard.. East Pond shows a positive drainage towards the outlet
structure. It shall be noted that Northern Engineering requested a variance to allow 0.0193
Ac-ft of the Water Quality Volume to be included in the total detention for East Pond and a
variance requesting that the 1'_ freeboard requirement be waived for the site.
The survey also indicates that the West Pond provides 0.025 Ac-ft of Water Quality Volume,
which is more than the required 0.018 Ac-ft required by the Drainage Report. The West Pond
has a total storage volume of 0.143 Ac-ft, which is greater than the required 0.109 Ac-ft and
shows that the detention volume for the 100-Year storm is 0.109 Ac-ft at an elevation of
5026.10' with 0.15' of freeboard. West Pond shows a positive drainage towards the outlet
structure.
The water quality outlet structures are in general conformance with the approved plans with
the exception of non -galvanized steel being used for portions of the structure. The water
quality plate for West Pond and East Pond have the correct number and size of holes. It is
noted that even though East Pond does not provide the required Water Quality Volume, the
ponds in.conjunction provide more Water Quality Volume than required for the site and
therefore it is anticipated that the existing condition will be accepted. In all, it is anticipated
that West Pond and East Pond are adequate wd.will perform as -intended.
