'> Dear Lyle, _
� g i ,
�.a^�.:-., _ . � .
#�` ' On or asound July 215t, 2005, a meeting took place at the Rovick
� ��, ,
Residenc�, 1625 Bohns Point Road, Orono regarding final approval of
" _ . reworking the swales along the north property of the site. Tom Kellog, I,
and you were present at this meeting. It was discusseci at this meeting
; that our proposed work to be done .to correct drainage patterns along
- the north property line were in line with the City of Orono's requests:
� Also at this meeting, it was di5cussed that an a5-bu�lt survey needs to be
� � completed by Gronberg � Associates of the reworked areas and then,
submitted to the city for final approvaL .
,
Enclosed you will find a copy of the as-built 5urvey dated August 4,
� 2005 and signed August 2�, 2005 by Mark Gronberg. Please take
� note that Gronberg � Associates took special care in takmg many
�elevation shots to verify that the location of the rec�uired swales east of �
house; and west of house along the north property line do exist. At t�he
time of Gronberg's survey work, we had al ready placed the draintile, rock,
and french drain ad�acent to the pool area. Most of the spot elevations
' shown on the pFan are approximately on top of the rock rip rap. The true
elevat�on of the bottom of the swale is approximately 6-8" below the
existing soil elevation along the property line as the swales move5 from
: east to west towards the lake. Therefore, some of the spot elevations
noted by Gronberg on the plan are not actual bottom of 5wale. Also, for
reference, the French drain and draintile trench is approximately 24" ,
' ' wide and 24" deep starting at near the northwest corner of the house
moving west following the line noted on the as built plan, as "swale".
