Re: Option A for Sunwood (Pond) Subdivision Landscape M District
Dear John:
We have prepared Option A for your review and consideration regarding the
improvement to the pond and related areas of the above
As you can see in a of Option A and Option B, there is a $20,714.00
reduction in cost. The reduction is due in great part to the el of
the pond equipment and the el of the copper sulfate
It is our belief that Option A provides a more realistic and safe level of
in addition to being more palliateable The cost per
home for Option A is $25.24/mo versus $82.78 for Option B. We
your concern and of Option A.
Should you have any q please do not hesitate to call.
Very truly yours,

RE: District for Sunwood
Dear Lee:
Attached hereto please find a copy of the 8" x 10" of the Sunwood
Tract on Pomerado Road. Cross-hatched are the areas proposed for the
You will note that the District includes:
° the pond area,
° the equestrian/ trail,
* landscaping around the pond and along the trail, and
° the area along the eastern side of the lots that rear onto Pomerado
Road.
Also a%tached please find the proposed ASSESSMENT DISTRICT BUDGET. The costs
are yearly and should cover all of the areas that we previously disc ssed. We
have added a twice a year of copper sulfate, the perforate "leaky"
pipe, a pumping station and vault, and a weir system and vault. It s our plan
to maintain the level of the pond, from the City water system. In a dition,
the BUDGET includes costs for trail creek and land-
scaping The specifics of the work to be perfomed on the Pond are
attached as Exhibit "A" to the ASSESSMENT DISTRICT BUDGET.
For y ur records we are also supplying you two blueline prints and one sepia
le of the plans for the DISTRICT IMPROVEMENTS. We trust that you
will ind all in order and be able to expeditiously schedule the of
the D STRICT before the City Council. As you know, we already have people
renting the homes. They are probably as anxious as we are to sell them the
homes.

EXHIBIT "A"
1. The lake will be filled with water four feet above the 428 foot culvert
level, i.e. to 432 feet. ~
2. The invert levels of the existing culverts at the western pond
will be raised to a level of 432 feet with fish guards installed. Rip rap
to the southern most outlet will be added.
3. The northern drainage pipe will be plugged to prevent flooding
of the adjacent property.
4. An automatic fill line from the city water ~upply will be installed. This
will ensure that the water level will be in the pond at 432 feet
at all times.
5. The middle of the lake will be cleaned of reed growth, while
a band of reeds along the north, east and west
This will save the natural of the wetlands for a wildlife refuge
and preserve.
6. Aeration will be provided to "The Pond" by a 4-inch "leaky pipe" down the
middle of the lake above the bottom approximately one foot. A
low duty ' 1-type blower, powered by a one
HP motor, will supply the air to the pipe. The equipment will be installed
in a security vault on shore.
7. Concret piers will be used to ancho aeration pipe work and serve as
substrate ensuring that f sh have hiding places from p
his he ps to establish an ecol gica ly balanced fish communit'. The
ake wi 1 be stocked with mosqu to f h as well as other appro riate fish.
he Mosquito Abatement program shan led by the Bureau of Vec or Control,
ounty of Public Hea th. he routinely nspects
all pond areas within the county and f larvae are found, is~
initiated and inspections are done weekly. This service, as well as supply-
ing mosquito fish, is free. Yearly of reed removal and thinning
will eliminate build-up of dead reed mats which foster mosquito breeding.

"The Pond"
Live Water Systems, Inc. has reviewed the grading and landscaping plans, as
well as the permeability report prepared by Geocon. We have had site meetings
with Geocon and with our consultants in fresh water biology. Based on the
intended uses of "The Pond" as a limited access, wildlife habitat and
wetlands, with bridle paths the of the pond, we
the following most cost course of action:
1. The lake should be filled with water four feet above the 428 foot
culvert invert level, i.e. to 432 feet.
2. The invert'levels of 'the existing culverts at the western pond
should be raised to a level of 432 feet with fish guards
installed. Rip rap to the southern most outlet should be added.
3. The northern drainage pipe should be adequately plugged to prevent
flooding of the adjacent private property.
4. An fill line from the city water supply'should be installed.
This will ensure that the water level will be in the pond
at 432 feet at all times. Algae growth ' in shallow warmer
waters. Deeper water tends to remain cooler.
5. The middle of the lake should be cleaned of reed growth,
while a band of reeds along the north, east and west
This will save the natural qualities of the wetlands for
a wildlife refuge and-preserve.
6. Protective substr~te should be added to the lake bottom to ensure that
fish have hiding places from .. This helps to establish an
ecologically balanced fish community. The lake should be stocked with
~osquito fish as well as other ap fish. The Mosquito
program is handled by the Bureau of Vector Control, County
of Public Health. to this agency, "The Pond" has
not een a mosquito problem in the pas~, in spite of its shallow water
and ense reed mats. The department routinely inspects all pond areas
with n the county and if larvae are found, is ' and
are done weekly. This service, as well as supplying
mosqu to fish, is free. Yearly of reed removal and
thinn ng will eliminate build-up of dead reed mats which foster
mosqu to
Based on the report from Geocon, we have figured that by filling the lake to
the 432 foot level, percolation hrough the in the worst case would

mpermeable as it is now. The s des are more permeable. However, some water

Evaporation data, based on information from Lake Miramar, that the
loss from only, is 55 to 62 inches per year. An average loss from
evaporation of 60 inches will require the addition of 3 million gallons of
water per year. Again, replacement water is desirable for its diluting effect.
