RE: Drainage and Flood Plain Conservation Easement
Horse Haven Estates-2710 Horse Haven Lane
College Station, TX
Dear Jay:
I am writing in response to your letter dated March 23, 2005, regarding the above
easement. I have reviewed the Correction Drainage and Flood Plain Conservation
Easement as you requested. It appears that Ofcsarzak is a successor-in-interest to the
Hermann tract. Therefore, Ofcsarzak is not a successor-in-interest of the "Owners of the
Development Land" as defined in the Easement and does not accrue a right to use the
easement through the Owners of the Development Tract.
I agree that the easement is non-exclusive; and, therefore, Ofcsarzak as a fee
simple owner and successor-in-interest to Hermann has the right to use the easement.
The only restriction on the use that I have noted in the Easement is under Section
2.3 which provides "neither Boriskie nor Hermann shall cause or pennit any alteration to
the Drainage Facilities, the Flood Plain Excavation Area or the Detention/Retention
Facilities". Therefore, the design and plans for Oakwood Custom Homes' use of the
detention facility cannot physically alter the Drainage Facilities, the Flood Plain
Excavation Area or the Detention/Retention Facilities without the consent of all the
parties to the agreement.
If you would like to discuss this further, please feel free to call.
Yours truly,
~~

Project Scope:
This report outlines the drainage improvements for Phases II and III of Horse Haven Estates.
This drainage report will consist of the requirements necessary for the improvements of this
16.44-acre site in accordance with the provisions of the Drainage Policy and Design Standards of
the City of College Station.
General Location and Description:
The project site is located on the northeast side of Highway 6 on Horse Haven Lane in the Carter
Creek Drainage Basin. Currently, the project site is undeveloped and exists in a relatively natural
state that is covered with native grasses, weeds, and light underbrush. This land generally slopes
from the northwest to the southeast with a grade of approximately 5.28%. The project site drains
directly into Carter Creek.
Drainage System Modeling:
For all drainage system modeling, the volume of runoff will be calculated. The drainage
calculations are summarized accordingly using the Rational Method: Q = CIA, where "Q" is the
runoff in cubic feet/second, "C" is the runoff coefficient, "I" is the storm intensity in inches/hour
for each selected frequency, and "A" is the drainage area in acres. The time of concentration was
calculated using the equation: T = D/60V. A minimum 10-minute time of concentration for all
calculations will be assumed. The selected frequencies will be 2, 5, 10, 25, 50, and 100-year
rainfall events. Tabulations of post-development runoffs for the site are provided.
Drainage Areas
The project site and surrounding areas were divided into ten drainage areas. Area 1 is
located west of the project site and consists of 11.13 acres. It drains to the southwest onto
the existing road and does not contribute to the storm sewer system of the site. Area 2
consists of 1.95 acres and drains to the southwest. It is located west of the site, drains into
the existing road, and does not contribute to the project site drainage. Area 10 is located
to the west of the site, directly under Area 2. It consists of 0.43 acres , drains to the
southwest into the existing road, and does not contribute to the project site drainage
system. Areas 3-9 are located on the project site and directly contribute to the drainage
system. Area 3 is 2.09 acres and drains to the southeast into Inlet 1. Area 4 is 1.26 acres
and drains to the southeast into Inlet 2. Area 5 consists of 2.16 acres and drains to the east
into Inlet 4. Area 6 is 1.58 acres with the majority of its runoff flowing to the east into
Inlet 5. Much of the impervious cover of Area 6 drains into Inlet 3. Area 7 is 2.39 acres
and drains to the southeast into Inlet 8. Area 8 is 1.82 acres and contributes runoff to
Inlets 7 and 9. Area 9 is 1.12 acres and drains to the southeast into Inlet 6. A map
displaying the drainage areas is provided.
Storm Sewer Inlets
Storm sewer inlets are a part of the storm sewer system evaluation. They were sized
according to the determined 10-year land area runoffs using the equation: Q = 3Ly3 12
,
where "Q" is the capacity in cubic feet/second , "L" is the length of the opening which
water enters into the inlet, and "y" is the total depth of water or head on the inlet. Tables
labeled "Inlet Sizing" are provided and show the sizes, as well as ground elevations for
the inlets for both the 10 and 100-year rainfall events.
Storm Sewer System
The program StormCad by Haestad Methods aided storm sewer system calculations.
Within this program, basic geometry and characteristics of a storm sewer system can be
defined. This would include data such as drainage basin calculations, type and
configuration of several types of inlet boxes , and controlling factors of the conveyance
system. From this program critical information can be determined about the storm sewer
system. Tables entitles "Pipe Sizing" are provided and contain information on the storm
sewer for both the 10 and 100-year rainfall events. The storm sewer system was designed
from the 10-year rainfall event.
According to the Drainage Policy and Design Standards of the City of College Station,
storm sewer pipes of 24 inches or less in diameter must be sized assuming 25% reduced
cross-sectional area. This guideline was met as the flow , when divided by the pipe
capacity, is less than or equal to 75% for all pipes of 24 inches or less in diameter for the
10-year rainfall event.
According to the Third Edition of the State Department of Highways and Public
Transportation Bridge Division Hydraulic Manual, "if the plotted hydraulic grade line
does not rise above the top of any manhole or above the gutter invert of any inlet, the
pipe system is considered satisfactory. Wherever it does rise above any of these points,
however, blow-outs through inlet slots and manhole covers will probably occur during a
design storm." The designed Storm sewer system for Horse Haven Estates meets these
guidelines for the 10-year rainfall event, and is therefore considered satisfactory.
Drainage Improvements:
As previously discussed, the majority of the site drains directly into Carter Creek. Because of
this , a detention basin will not be necessary. The storm sewer will discharge into a channel at the
southern corner of the site and directly into an existing non-functional stock tank (Drainage
Basin Easement Vol. 4107 , Pg. 07). Calculations for the channel are provided.
Results:
As previously mentioned, the designed storm sewer system is satisfactory for the project site.
Calculation results and design parameters for the system are shown in the Pipe Sizing tables
provided. Runoff calculations and results for the drainage areas are also provided.

RE : Horsehaven Extates Subdivision Phase 2
Dear Mr. Gibbs ,
We bel ieve we have made the changes that you required to have the plans approved and a
Development Permit issued for Phase 2 only per our meeting last Friday. We have attached the
latest cost estimate and our estimate for Appomattox Drive which our client will provide surety
for in-lieu of actual construction at this time . We have notified him that he is required to
provide the surety prior to being allowed to pick up the DP . We hope to clear up the remaining
issues for Phase 3 next week and submit our plans for that phase . If you have any questions
please contact me .
Very sincerely yours ,
Municipal Development Group
