Re: Comments on Waterside Estates #2
Dear Mr. Anderson:
I have reviewed the referenced plans and have the following comments to
offer:
1 Standard Details should be included in the plans.
2 - Landscape and irrigation plans should be submitted.
3 - A thirty foot radius should be provided for the connection of
Spyglass Drive to Parkway Blvd. and for the connection of
Waterside Drive to MacArthur Blvd.
4 The inlets at paving station 2+00 on Greenway Drive should be
relocated to a common property line to allow for driveway
access to Lot 6.
5 - You should try to use a 250 foot minimum vertical curve on
Greenway Drive as opposed to the two 100 foot vertical curves.
6 - The grade on Westlake Drive as it approaches Greenway Drive
exceeds the maximum allowable grade of 5%.
7 - The alley between Lots 34 and 35, Blk D exceeds the maximum
allowable grade of 5%.
8 - I am concerned about the ponded/standing water that will be in
the laterals that discharge into the existing lake. Each of
the inlets will have a minimum of one foot of water continually
standing in them.
9 - The details for the 6 X 5 box culvert do not show where the
proposed water line will go in Spyglass Drive. Please show
where that water line will be located.
10 - Additional information should be provided about the type of
brick and railing. These items will need approval by the City.

11 - The manhole spacing on Line H of the sewer lines exceeds (500)
feet.
12 - An additional valve should be added on the water line in the
vicinity of Spyglass Hill as it crosses over the existing lake.
13 - The manhole at Station 6+37.4 of Line F should be relocated
away from the proposed storm drainage.
14 - On the water and sewer layout sheet there are several other
comments not specifically addressed here that should be
corrected in the plans.
15 - In the sewer profiles, notice the locations where concrete
encasements should be provided. All concrete encasements
should be a minimum of 20 foot in length.
16 - At Station 1+30 of Line K and Station 9+80 of Line A a minimum
of four (4) foot of coverage should be provided.
17 - The entire grading plan should be provided. The grading plan
that was provided only covers a portion of the subdivision and
parts of the grading plan provided does not include the
finished floors.
18 - Based on the elevations provided, it appears as though the
finished floors shown for the houses on the east side of
Westlake Drive and Westlake Court near the low point inlets
should be elevated to at least an elevation of 459.7. Also,
you should provide and show some type of positive overflow at
all the low point inlets.
There are other minor comments at various places throughout the plans that
should also be addressed prior to resubmitting these plans. Once these
changes have been made, the plans should be resubmitted along with these
mark-up sets.
If you have any questions or comments, please feel free to contact me at
your convenience.
Sincerely,
