CONSENT TO EXTENSION OF TIME ON
MEMORANDUM OF UNDERSTANDING ON
WILLIAMSON COUNTY MUNICIPAL
UTILITY DISTRICT NO. 3
WASTE DISCHARGE PERMIT AMENDMENT
The undersigned are parties to that certain agreement entitled
"Memorandum of Understanding on Williamson County Municipal Utility
District No. 3 Waste Discharge Permit Amendment ", executed in
October, 1984, hereafter referred to as the "Memorandum of Under-
standing". For reference, a copy of the Memorandum of Understanding
is attached hereto. The defined terms used in the Memorandum of
Understanding have the same meanings when used in this consent.
It was contemplated at the time the Memorandum of Understanding
was executed, and the basis for the execution of the Memorandum of
Understanding was, that the Regional System to be constructed by
Brushy Creek Water Control & Improvement District No. 1 ( "BCWCID ")
would be in operation by January 1, 1987, or that construction
thereof would have commenced by that date and be completed by
July 1, 1987. As a result of a change in policy by the current
Board of Directors of BCWCID, BCWCID has decided not to proceed
with the Regional System. Accordingly, the timetable for the
Regional System to be constructed and placed in operation is
expected to be extended beyond the dates originally projected, which
the parties agree will probably prevent the MUD from complying with
all of its obligations under the Memorandum of Understanding and
within the time limitations specified therein. The parties
acknowledge that a good faith and serious effort is being made to
proceed with the construction and operation of the Regional System
on a different organizational basis, and that there are reasonable
prospects that the Regional System will be accomplished on the new
basis. In Paragraph 4 of the Memorandum of Understanding, the
parties recognized that the Regional System may not be operational
within the time periods specified in the Memorandum of Understanding,
and it was accordingly provided that by mutual agreement, the time
limitation specified in the Memorandum of Understanding may be
extended. Because the Regional System will be able to provide waste-
water service to all of the undersigned parties, it is of benefit to
them that the time limitation be extended so as to enable the
Regional System to proceed and to enable the MUD to be a participant
in the Regional System, rather than operating through another waste-
water treatment and disposal system.
Accordingly, in consideration of the mutual benefits which will
accrue and the obligations which pertain between the parties to the
Memorandum of Understanding, the undersigned parties agree that the
provisions of paragraph 2(b) of the Memorandum of Understanding
are superseded, and that the MUD may continue after January 1, 1987,
to discharge Effluent in quantities up to 400,000 gallons per day
average into the South Brushy Creek Watershed upstream of Site No.
7, with treatment at the levels specified in Special Conditions la
and 2a on pages 2 of 19 and 2a of 19 in the MUD's waste discharge
permit No. 12200, issued February 19, 1985, and that such discharge
may continue until the entire Phase I of the Regional System is
completed and placed in operation, and the MUD is able to use the
Regional System for all of its wastewater treatment and disposal
needs; provided that construction of the Regional System shall be
underway as of January 1, 1987, and the completion thereof shall be
projected by the engineers for the Regional System to be no later
than January 1, 1989; provided further that the MUD shall discontinue
the discharge of any Effluent to South Brushy Creek as soon as the
Regional System is able to accept all of the MUD's wastewater and
treat and dispose of the same, regardless of the stage of completion
of the Regional System at the time. If it is determined that the
entire Phase I of the Regional System will not be completed and
able to accept, treat and dispose of all of the wastewater generated
by the MUD by January 1, 1989, or if in fact the Regional System
fails to become operational by that date, then as soon as such fact
is known and established, the MUD shall then proceed to provide treat-
ment of the wastewater it discharges at the levels of quality speci-
fied in paragraph 2(d) of the Memorandum of Understanding.

MEMORANDUM OF UNDERSTANDING
ON WILLIAMSON COUNTY MUNICIPAL UTILITY
DISTRICT NO. 3
WASTE DISCHARGE PERMIT AMENDMENT
Oct. 23, 1984(Rev'd.;
The undersigned parties desire to reach an amicable resolution
of the issues relating to the application of Williamson County
Municipal Utility District No. 3 to amend its waste discharge
permit No. 12200 and to foster measures to protect the quality of
surface and ground water resources in the Upper Brushy Creek Water-
shed (the "Watershed "). The undersigned have agreed that a regional
wastewater collection, treatment and disposal system for the Water-
shed offers the most practical method for collecting, treating and
disposing of municipal and domestic wastewater in the Watershed if
the same is economically feasible as determined by BCWCID (as
hereafter defined) and that the concurrence of the undersigned
parties in this Memorandum of Understanding is an important step in
accomplishing a regional system. The proposed regional wastewater
collection, treatment and disposal system, including the Regional
Plant, the Interim Project and the Interceptor, as the same are
hereafter described, is hereafter referred to as the "Regional
System ". In furtherance of the objectives stated above, the parties
hereto agree as follows:
1. Regional Facilities.
(a) Brushy Creek Water Control & Improvement District
No. 1 of Williamson and Milam Counties ( "BCWCID ") shall undertake
to secure a permit for and to finance and construct a wastewater
treatment plant (the "Regional Plant ") as a part of the Regional
System, which plant shall be in operation by the applicable date
specified in paragraph 3(1). The Regional Plant shall be located
in the Brushy Creek Watershed and is proposed to be located on a
site east of IH 35.
(b) BCWCID shall undertake to finance and construct a
line for untreated wastewater (the "Interceptor ") extending ap-
proximately from the point of discharge on South Brushy Creek above
Site No. 7 (as defined below) authorized under the City of Cedar
Park's original and unamended waste discharge permit No. 12308, to
Ole Regional Plant, which Interceptor shall be in operation by the
pplicable date specified in paragraph 3(1).
(c) BCWCID may, but is not obligated to, construct a
line to carry untreated wastewater from a point on South Brushy
Creek approximately 3,000 feet downstream of the U.S. Soil Con-
servation Service Reservoir at Site No. 7 on South Brushy Creek
( "Site No. 7 ") to a lift station on Brushy Creek near the City of
Round Rock that will pump the wastewater via a wastewater main over
to the Onion Creek watershed and into the Onion Creek interceptor
of the City of Round Rock for transportation to and treatment in
the existing City of Round Rock wastewater treatment plant (the
"Interim Project "). The Interim Project will provide interim
wastewater service to the South Brushy Creek Watershed pending
construction of the Regional Plant and Interceptor (as above
defined). If the Interim Project is constructed, it shall be in
operation by the applicable date specified in paragraph 3(1).
(d) BCWCID has petitioned the Texas Department of Water
Resources pursuant to Sections 26.081 - 26.083, Texas Water Code,
for and shall actively seek (1) the delineation of the upper Brushy
Creek Watershed, or a portion thereof sufficient for the implementa-
tion of an areawide management system, as a wastewater management
region, and (2) the designation of itself as the regional waste-
water management entity for the defined region.
(e) If BCWCID should for any reason fail or decline to
proceed with the regionalization and construction efforts and the
necessary waste discharge permit application or applications out-
lined in paragraphs 1(a) -1(d) above, the City of Round Rock may,
but is not obligated to, proceed with such regionalization and con-
struction efforts and necessary permit applications.
2. Discharge to South Brushy Creek Watershed.
(a) Williamson County Municipal Utility District No. 3
(the "MUD ") agrees to construct its wastewater treatment facilities
in increments, as set forth below, and further agrees not to commence
construction of any increment in advance of the date reasonably
determined by the MUD to be the date by which construction of such
increment should be started in order for that particular increment
to be operational in time to meet the MUD's reasonably pro :4 , cted

(b) Until (1) January 1, 1987, or (2) the Regional System
is operational and able to meet the wastewater service needs of the
MUD on a permanent basis as development of the MUD progresses, or
(3) the Bypass Line [as identified in paragraph 2(f) below] is
operational and able to meet the Effluent discharge requirements of
the MUD on a permanent basis as development of the MUD progresses,
whichever of the foregoing three events first occurs, the MUD may
discharge treated domestic and municipal effluent (the "Effluent ")
in quantities up to 400,000 gpd average into the South Brushy Creek
Watershed upstream of Site No. 7 to serve present and future waste-
water customers of the MUD. The Effluent shall be treated to the
level specified in the MUD's existing waste discharge permit
No. 12200.
(c) When the reasonably projected needs of the MUD indicate
that it will be necessary for the MUD to increase (at any time
after January 1, 1987) its discharge of Effluent to the South Brushy
Creek watershed beyond 400,000 gpd, and if, at the time such need
is determined, (i) the Regional System is not reasonably projected
to be in operation by the applicable dates specified in paragraph
3(1), including making provision for paying the MUD for its wastewater
faclities or giving the MUD credit on its capital cost of participation
in the Regional System for the cost of the MUD's wastewater facilities,
as more specifically provided in paragraph 3(2) below, and (ii) the
Regional System is not reasonably projected to have the capacity to
serve the MUD's wastewater needs on a permanent basis upon full
development of the MUD, then the MUD may proceed to construct the
Third Expansion of its wastewater treatment facilities and, after
January 1, 1987, may increase its discharge of Effluent to the
South Brushy Creek Watershed beyond 400,000 gpd.
(d) If the MUD constructs the Third Expansion of its
wastewater treatment facilities, regardless of the point of dis-
charge to the South Brushy Creek Watershed used for discharge of
the Effluent, the MUD agrees to then treat all of its Effluent
prior to discharge to meet the following 30 -day average Effluent
quality parameters: 5 mg /1 BOD5, 5 mg /1 TSS, 2 mg /1 ammonia
nitrogen, 2 mg /1 phosphorous, 5 mg /1 D0, and 2 mg /1 of chlorine
after 45 minutes contact time. The MUD also agrees to incorporate
in all of its wastewater treatment facilities and operations at the
time it constructs the Third Expansion the requirements specified
in Exhibit "A" attached hereto.
(e) In its pending application and in any future applica-
tions to amend its existing waste discharge permit No. 12200, or
for another waste discharge permit, the MUD agrees it shall apply
for and in good faith seek to obtain authorization for the Effluent
quality parameters and the wastewater treatment plant design and
operational features specified in paragraph 2(d) above, which shall
be applicable when the Third Expansion of the District's wastewater
treatment facilities becomes operational. The MUD further agrees
to comply with those parameters and features when the Third Expansion
becomes operational whether or not they are incorporated in any
permits or amendments to permits issued to the MUD, unless prohibited
from doing so by any court or agency having jurisdiction, or by law
or regulation, or unless specifically prohibited by provision of
the MUD's permit.
(f) The MUD agrees to participate on a pro rata basis
with others in the cost of construction of an Effluent discharge
line that would transport Effluent from the Cedar Park area to a
point of discharge on South Brushy Creek below Site No. 7 (the
"Bypass Line ") and agrees to use the same for the discharge of
Effluent from the MUD's wastewater treatment facilities when the
same is operational and the operator of the Bypass Line is able and
willing to accept and discharge Effluent from the MUD. This require-
ment may be satisfied by the MUD's participating in and using the
outfall line described and referred to in paragraph 1(b) of that
certain agreement entitled "Memorandum of Understanding -Upper Brushy
Creek Regional Wastewater System ", executed in June, 1984, between
BCWCID, the City of Round Rock, Bill Milburn, Inc., the City of
Cedar Park, and the Adla Nelson Avery Ranch Partnership (the "Milburn
Memorandum of Understanding "), to which agreement reference is made
for a description of the outfall line. BCWCID agrees to include
the Bypass Line in and as a part of the Interceptor and to reimburse
the MUD and other participants in the Bypass Line, or otherwise
give credit to the MUD and such other participants on their costs
of participation in the Regional System, for their costs of participa-
tion in the Bypass Line.
3. When Regional System Becomes Operational.
At such time as the Regional System becomes operational, the
MUD agrees to terminate the use of all or part (as hereafter specified)
of its wastewater treatment facilities and deliver all or part (as
hereafter specified) of the untreated wastewater collected by the
MUD to the Regional System at the upstream end of the Interceptor,
subject to and in accordance with the following:
(1) Either (i) the Interceptor and the Regional Plant or
(ii) the Interim Project shall be operational by January 1, 1987,
or the actual construction thereof shall be underway by January 1,
1987, with a reasonably projected date of no later than July 1,
1987, for the same to be completed and placed in operation.
(2) The MUD shall be paid or given credit on its capital
cost of participation in the Regional System in an amount at least
equal to the MUD's bonded indebtedness, amounts owed under facilities
purchase agreements, and other obligations of the MUD outstanding
at the time the MUD connects to the Regional System on (i) that
portion of the then existing wastewater treatment facilities serving
the MUD which will no longer be needed by virtue of the MUD's
connection to the Regional System, and (ii) the Bypass Line.
(3) The MUD shall be permitted to continue to operate
those wastewater treatment and discharge facilities for which it
has not been paid or given credit in full on its capital cost of
participation in the Regional System, and shall further be permitted
either to (i) continue to use the Bypass Line for the discharge of
any Effluent resulting from such continued operation or (ii) discharge
any such Effluent at the MUD's current point of discharge if the
Bypass Line has been converted to a line to transport untreated
wastewater or is otherwise unavailable to the MUD for discharge of
Effluent.
-5-
(4) The MUD shall be'assured of permanent wastewater
treatment capacity in the Regional System (including specifically
the Interim Project, if constructed) which, together with any capacity
in the MUD's wastewater treatment facilities that may continue to
be used by the MUD as herein provided, will be adequate to serve
the present and future wastewater customers of the MUD on a permanent
basis and to permit full development of the property within the
boundaries of the MUD in accordance with the reasonably projected
schedule of development of the property.
(5) BCWCID shall have determined that the Regional System
is economically feasible, provided, however, the parties agree that
this condition is not satisfied if the Capacity Charge to customers
who make a lump sum payment for wastewater service rights or capacity
in Phase I of the Regional System, as provided in the proposed
"Wastewater Disposal Contract Between Brushy Creek Water Control &
Improvement District No. 1 and Williamson County Municipal Utility
District No. 3 "(Draft 10/22/84), exceeds $2,000 per living unit
equivalent of service.
(6) The Texas Water Development Board shall have designated
BCWCID as the regional wastewater management entity pursuant to
Section 26.083(b), Texas Water Code.
4. If Regional System Not Ready.
If either (i) the Interceptor and the Regional Plant or (ii)
the Interim Project is not operational or is not reasonably projected
to be operational within the applicable time period specified in
paragraph 3(1), then the undersigned parties shall not be bound by
the terms of this Memorandum of Understanding except for the provisions
of paragraphs 2(d), 2(e) and 2(f), above, which shall continue in
effect; provided that this time limitation may be extended by mutual
agreement of the parties hereto.
5. Withdrawal of Protests.
None of the parties hereto shall object to, protest or other-
wise oppose any existing, pending or proposed permits, applications
for permits or for amendments to permits, or renewals or extensions
of permits of the MUD to discharge Effluent that are provided for
in and are in compliance with this Memorandum of Understanding, and
any party hereto presently objecting to the same agrees to withdraw
its protest, opposition or objection.
-6-
6. Other Provisions.
(a) After designation of BCWCID as the regional wastewater
management entity pursuant to Section 26.083(b), Texas Water Code,
the MUD agrees upon request of BCWCID to transfer its waste discharge
permit No. 12200 to BCWCID and to permit BCWCID to operate and
maintain the wastewater treatment plant authorized by the permit.
BCWCID agrees to operate said plant in compliance with this Agree-
ment. BCWCID agrees that the rates it charges the MUD or its customers
for operation and maintenance of the plant authorized by said permit
No. 12200 shall be based on the reasonable costs of such operation
and maintenance.
(b) All parties hereto agree to endorse the planning,
development and implementation of the Regional System and to co-
operate with BCWCID in obtaining the participation of the potential
users of the Regional System in financing the cost thereof if BCWCID
determines that the Regional System is economically feasible and
the Texas Water Development Board designates BCWCID as the regional
wastewater management entity pursuant to Section 26.083(b), Texas
Water Code.
(c) The parties hereto agree that this Memorandum of
Understanding is solely for the benefit of the parties hereto, and
that none of the undersigned by executing this Memorandum of Under-
standing waives any rights it may have or assert as to any party or
parties not a signatory hereto.
(d) This Memorandum of Understanding shall be binding on
and shall inure to the benefit of all parties hereto and their
respective heirs, successors, representatives and assigns.
(e) This Memorandum of Understanding shall not be effective
as to any of the parties hereto until all of the parties named
below have executed the same.

SECTTON TI - LOCATION
The proposed Fern Bluff Municipal Utility District consists of two
non - contiguous tracts of 222.71 and 472.156 acres totaling 694.866
acres. It is located north of Austin and west of Round Rock in
Williamson County, Texas. The District is bordered on the north side
by County Road 174 (Hairy Man Rd.) and Brushy Creek and on the south
side by Williamson County M.U.D. No. 2 (Brushy Creek south
subdivision). Great Oaks Drive, as it passes through the Brushy Creek
south subdivision, borders the eastern tract. The proposed District is
located within the City of Austin's Extra - Territorial- Jurisdiction
(ETJ) and a small portion of the eastern tract's southeastern corner is
located within the City of Round Rock's ETJ. FIGURE 1 shows the
location of the proposed Fern Bluff M.U.D. in relation to the greater

SECTION III - HISTORY AND LAND USE
The San Gabriel Watershed has a rich history beginning with
original settlement of the San Xavier complex of missions in 1746.
Permanent settlement in the watershed, as it is known today, began in
the early 1800's with immigrants from a variety of nations. Two early
cattle drive trails, the Chisholm and the Shawnee, crossed the
watershed in the vicinity of Georgetown. Both trails passed through
the general area of the proposed District on their way north to Waco
and North Texas. Development in the Round Rock area was relatively
slow until about 1970 when Austin began to rapidly attract new
inhabitants. Many of these people choose to live in the smaller
communities which lie on the outskirts of Austin and commute to work in
Austin. Although this trend has continued, recent commercial and
industrial growth in the Round Rock area has provided more immediate
area employment. See ATTACHMENT - Market Study for more information.
The proposed District area lies west of the City of Round Rock and
east of the City of Cedar Park. This area has traditionally been used
for ranching and farming however, Austin and Round Rock's growth
patterns have placed the proposed District in the path of future
residential and commercial development. The site is close to major
area employers such as Abbott Laboratories, Westinghouse Heavy Motor
Division, McNeil Consumer Products, Weed Instruments, B.J. Hughes and
the recently announced 3 -M Research Facility. The Parmer Lane
extension (under construction) linking R.R. 620 to F.M. 1325 also makes
such employers as Texas Instruments, I.B.M., Austin White Lime, M.C.C.
and Balcones Research Facilities accessible to the proposed District.
The existence of these employment centers, along with the general
appeal of the Round Rock area and its outstanding school district, has
inspired rapid residential and commercial growth in this area. Brushy
Creek (north and south), The Hermitage, Cimarron, Chisholm Valley, and
Greenslopes are all examples of successful subdivisions located in the
rapidly growing Round Rock area.

SECTION IV - EXISTING GEOLOGY AND TOPOGRAPHY
General Geology
The proposed District lies along the Balcones Escarpment, which
delineates locally the eastern boundary of the Great Plains and western
boundary of the Blackland Prairie. The planning area lies in the San
Gabriel River watershed which is a tributary of the Brazos River
Basin. Physiographically, the proposed District lies within the Gulf
Coastal Plains and is well situated on the Austin Chalk.
Williamson County lies almost equally within two great
physiographic provinces. The eastern part, approximately one -half of
the county, lies in the Gulf Coastal Plain and western part in the
Great Plains. The provinces here are physiographically somewhat
similar in that they constitute high broad undulating plains differing
locally in surface dissection and relief.
The western, or Great Plains, province is occupied by the Grand
Prairie, which just south of Williamson County in the vicinity of the
Colorado River, merges with the high dissected western limestone
plateau known as the Edwards Plateau. The part of the Grand Prairie in
western Williamson County is known as the Lampasas cut plain, and
surface features limestone formations and native vegetation which is
identical to those features of the adjacent areas of the Edwards
Plateau.
Topography
The area landscape is typically rolling hill country with slopes of
generally 3 -10%. Elevations range from approximately 740 to 870 feet
above mean sea level. The site is mostly comprised of uncultivated
farm land and oak - juniper savannah. The northern edge of the east
tract borders County Rd. 174 and Brushy Creek. The District is
separated from the road by a relatively steep limestone bluff which
runs parallel to the creek and road. Slopes from this bluff south
toward the Brushy Creek development are relatively flat. Both of the
tracts are bisected at various locations by major natural draws. A
natural fern covered limestone bluff runs parallel to Brushy Creek
within the eastern tract of the proposed District and is the source of
the District's name. The area surrounding this bluff line has been
planned as greenbelt so that the beauty of the site can be preserved.
Watersheds
The proposed District falls immediately within the Brushy Creek
watershed (Segment 1244). Brushy Creek flows into the San Gabriel
5
River east of Round Rock which then flows into the Little River, a
tributary of the Brazos River and the Gulf of Mexico. Drainage from
both tracts currently flows north by way of naturally occurring draws
which bisect the sites at various locations and flow into Brushy
Creek. The developed project proposes to contain runoff in underground
pipes, open drainage ways and conduct water at a regulated rate to
Brushy Creek after the appropriate detention time. The 100 -year flood
plains for each tract have been determined using HEC -II computer models
of the watershed.
Underlying Soils
Soils underlying the proposed District are generally of the
Eckrant- Georgetown Association. This association is characterized by
very shallow to moderately deep, calcareous and noncalcareous, stony,
cobbly, and loamy soils formed in undurated fractured limestone located
on uplands. Soils in the Eckrant- Georgetown Association are generally
nearly level to hilly soils on broad uplands. The Eckrant soils are
generally in the more sloping areas on ridges and hills and along
drainageways. The Georgetown soils are mainly on broad ridges and
gentle side slopes. Typically, Eckrant soils have an extremely stony,
very dark gray surface layer about 11 inches thick. The underlying
material is undurated fractured limestone. The Georgetown soils have a
slightly acid, brown stony clay loam layer about about 7 inches thick.
The underlying material is undurated fractured limestone.
These soils are suited to urban uses. Live oak, elm, and other
native trees add beauty and shade that are desirable for residential
areas. The limestone substratum provides a good base for foundations
and streets but is difficult to excavate for ditches and trenches.

,SECTION V - ENVTRONMENTAL IMPACT OF THE DEVELOPMENT
Because the site consists of flat to gently rolling terrain, the
amount of cut and fill required for streets and building foundations
will be minimal. Utilities will be placed in the street right -of -way
whenever possible to avoid extra excavation. Areas with excessive
slopes will be utilized as greenbelts or open space areas.
Subsidence
Due to the general nature of the underlying geology, and the fact
that no groundwater extraction by the District is planned, subsidence
is not considered to be a factor in the development of the proposed
District.
Groundwater Level Within the Region
Because groundwater is not planned as the source of water for the
proposed development, existing groundwater levels within the area are
not expected to be adversely affected by the creation of this District.
Groundwater Recharge Capabilities
According to most sources, the proposed District lies over the
Edwards Aquifer recharge zone. Although interpretations of exactly
what comprises the recharge zone differ, it is generally accepted that
outcrops of the Edwards limestone and areas of major and minor faulting
within the limestone are areas of infiltration. The majority of
recharge to the Edwards occurs as a result of seepage by surface water
impoundments and infiltration by surface streams as they pass over
major and minor faults within the zone. Runoff from the proposed
development will be detained and diverted to Brushy Creek. Because
recharge of this aquifer is typically not a result of direct
infiltration through major soils, but rather direct inflow by streams
and creeks, the increased impervious cover which will occur as a result
of the development of this District will not adversely affect the
recharge capability of the aquifer.
The District proposes to use water supplied from the City of Round
Rock which currently utilizes a combination of surface water and
several water wells to make up the City's water supply. However, the
increasing majority of the City's water is supplied from a 6 -mgd
surface water treatment plant (planned for expansion to 18 mgd) which
has its raw water intake located on the North Fork Reservoir near

Georgetown. This plant is contracted with the Brazos River Authority
for expansion to 18 mgd from the North Fork Reservoir and is currently
pursuing additional surface water supplies from the Stillhouse Hollow
Reservoir project. In view of the fact that the regulating authority
has made commitments for these future expansions, the effects of the
proposed District on the water levels of the Reservoir and therefore
its recharge capabilities to underlying aquifers are expected to be
negligible.
Runoff
Creation of the District would have an impact on stormwater runoff
rates due to the nature of the proposed development and the increase in
impervious cover area. The proposed District lies, for the most part,
within the City of Austin's E.T.S. and the design of drainage
facilities within the District will conform to the City's existing
drainage requirements and detention ordinance. Drainage improvements
to serve the District will be designed to contain the 100 year storm
event and all channeled drainage will be contained within proposed
easements. All foundations will be constructed at least one foot above
the 100 year flood plain.
surface Water Oua1it
The quality of waters within the Brushy Creek Watershed are
generally good in the upper watershed areas but deteriorate rapidly as
waterways receive runoff from urban and agricultural areas and
discharges from wastewater treatment facilities. In addition, natural
geologic structures in the upper watershed, primarily limestones,
create an alkaline condition in the creek with high dissolved solids
concentrations. Although more water quality analysis is needed in this
area, preliminary studies show high fecal coliform counts indicative of
inadequately treated wastewater or agricultural pollution.
This development intends to utilize the Brushy Creek WC &ID's
proposed regional wastewater treatment facilities. Because no
immediate waterway discharge will occur, and City of Austin standards
for detention and runoff control will be followed, no degredation of
surface water quality is anticipated as a result of this development.

Groundwater Quality
The major groundwater aquifers in the immediate area of the
proposed District are the Hensel and the Edwards. Both of these
Aquifers are fresh water bearing. Outcrops of aquifers in Williamson
County are quite common with outcrops of the Trinity sands and the
Edwards occuring in the central part of the County. Groundwater occurs
under water table conditions at the outcrop. Water levels generally
fluctuate with rainfall. Recorded water levels indicate artesian
conditions in the downthrown side of faults near Georgetown and Round
Rock. Recharge to the Edwards Aquifer comes principally from
infiltration of streams and rivers crossing the outcrop. Direction of
groundwater movement is believed to be controlled by the regional dip
of the Edwards and to a lesser extent by joints and fractures
associated with the Balcones Fault zone. Generally, groundwater
movement is southeastward.
The Hensel Sand Aquifer recharges primarily in Burnet County where
the formation outcrops and from the overlying Glen Rose formation and
underlying Cow Creek limestone. Minor aquifers and water bearing
formations in Williamson County include the Austin Chalk, the
Taylor- Navarro Group, the Midway Group, the Wilcox Group, quaternary
terrace and alluvium.
Because the majority of groundwater recharge to the Edwards occurs
as streams pass over faults and cracks in the water bearing formations
themselves, and not through infiltration through exposed outcrops, the
proposed development should not have a direct adverse effect on the
quality of groundwater in this area. Further, by seeking wastewater
treatment and disposal from the Brushy Creek WC &ID, the anticipated
ultimate discharge point for treated wastewater will be east of the
generally recognized limits of the Edwards Underground Recharge Zone.

SECTION VI — ECONOMIC IMPACT OF DISTRICT
The creation of the Fern Bluff M.U.D. will have an impact on the
taxes within the proposed District. A property tax rate of $0.92/$100
will be assessed on 100% of the appraised value of all taxable property
within the District. This tax rate compares to other taxing
authorities as shown below (1984 figures).

In addition to the proposed District taxes, property owners within
the District will also pay property taxes to Williamson County
($0.2334/$100 on 100% value) and Round Rock I.S.D. ($1.17 /$100 on 100%
value). This equates to a total property tax rate of $2.32/$100
valuation.
The District proposes to purchase water service from the City of
Round Rock and purchase sewer service from the Brushy Creek WC &ID. The
costs of operation and maintenance of the M.U.D. water and wastewater
system should be absorbed through water and wastewater rates.

SECTION VII - LAND USE SUMMARY AND POPULATTON GROWTH
Fern Bluff is a multi -use development planned by the Bill Milburn
Company which will include single family - detached, planned unit
developments, duplex and multi - family housing as well as office /retail
and commercial land uses. As stated previously, the proposed
development consists of two non - contiguous tracts on either side of
Brushy Creek. The west tract totals 222.71 acres while the east tract
totals 472.156 acres for a total of 694.866 acres.
The west tract is planned to include 121.05 acres of single
family- detached, 32.53 acres of single family attached and 12.15 acres
of duplex housing. The remainder of the tract consists of
approximately 48.66 acres of greenbelt and 8.32 acres of right -of -way.
Most of the greenbelt area takes place adjacent to County Road 174
along Brushy Creek. Single family- detached densities are planned at 4
units per acre, single family attached at 12 units per acre and duplex
housing is planned at approximately 12 units per acre. Major access to
the west tract of Fern Bluff will be provided by County Road 174 as
well as extension of Hillside Drive and O'Connor Drive from the Brushy
Creek subdivision.
The east tract of Fern Bluff is planned to include 282.19 acres of
single family- detached, 51.67 acres of planned unit development, 14.90
acres of duplex and 11.97 acres of multi - family housing. The east
tract will also include 24.05 acres of office /retail area and 3.68
acres of commercial area. Approximately 36.29 acres of greenbelt area
includes a natural limestone bluff covered with lush fern growth for
which the development was named. The remaining 33.35 acres of land
being used as right -of -way. Densities for single family- detached and
duplex housing are approximately the same in the west tract. Densities
for planned unit development housing will be approximately 6
units /acre, and multi - family housing density is planned at
approximately 20 units /acre. Major access to the east section of Fern
Bluff will be provided by County Road 174, an extension to R.M. 620 as
well as two major streets terminating in Brushy Creek. FIGURE 2 shows
the proposed land plan for the Fern Bluff development. TABLE NO. 2
shows the various land uses and acreages planned for the Fern Bluff
development. TABLE No. 2 gives estimated populations associated with
each land classification. Population figures are based on 3.2 persons
per single family and duplex unit, 2.5 persons per PUD unit and 1.7
persons per multi - family unit.

Dwelling Unit Equivalents. D.U.E.'s differ somewhat from the commonly
used L.U.E.'s (Living Unit Equivalents) in that they are based on the
actual number of units rather than a theoretical number based on water
or wastewater usage. D.U.E.'s are useful in making a more equitable
distribution of necessary charges to District residents. Although
single family L.U.E. and D.U.E. amounts are basically the same,
multi - family, commercial, retail and industrial figures are different.

SECTION VTTT - UTTTJmv_ RERVTCE ATTERNATTVES
The proposed Fern Bluff M.U.D. lies in the southwest portion of
Williamson County and west of Round Rock. Although this area is
currently within both the Austin and Round Rock E.T.J., City service
lines in this area for water and wastewater do not exist as of this
writing. Services for water distribution and wastewater collection are
not currently planned for this area by either entity as capital
improvement projects.
The proposed District also lies within the boundaries of the
existing Brushy Creek Water Control and Improvement District. This
governmental body has the authority to regulate and provide water,
wastewater and drainage for the Brushy Creek Watershed, although they
choose not to regulate water and drainage at this time. The Brushy
Creek WC &ID is currently proposing a regional wastewater treatment
plant to be located at the confluence of Brushy and Chandler Creeks,
east of Round Rock. This plan will be discussed in greater detail in
the following text.
WATER SERVICE ALTERNATIVE EVALUATTON
As previously stated in the preceeding text, the existing Brushy
Creek WC &ID does not provide water service in this area and does not
have any plans to do so in the near future. The City of Austin does
not presently supply water in this area and also does not have any
plans to do so in the near future.
Groundwater
Water service from water wells is not deemed feasible due to the
fluctuating levels of underlying groundwater. Municipalities and
utility districts which rely strictly on groundwater have experienced
dangerous shortages during summer months in recent years. This fact is
evidenced by the fact that water wells for the adjacent Williamson
county M.U.D. NO. 2 (Brushy Creek) were pumped almost dry several times
during the summer drought of 1984. For this reason, groundwater is not
deemed a reliable sole source of potable water for the proposed
District.
Service From Existing Utilities
The most cost effective source of water for this District is the
City of Round Rock. Evaluation of the City of Round Rock's water
supply and distribution system shows that the strong portion of the
system is the northern segment beginning with the City's existing 6.0
mgd surface water treatment plant located adjacent to the Westinghouse

facility just west of I.H. 35. This plant processes water from Lake
Georgetown (North Fork Reservoir) and is planned for future expansion
up to a total of 18 mgd. This matches the City's existing commitment
for water supply out of the lake by the Brazos River Authority (BRA).
Recent preliminary engineering studies by BRA indicate that it is
feasible to further increase the amount of raw water available to the
City of Round Rock by construction of the Stillhouse Hollow Reservoir
project. This project which includes the construction of a reservoir
and pipeline downstream to Lake Georgetown would make available
additional supplies of raw surface water at Lake Georgetown. Future
construction of an additional raw water pipeline from Lake Georgetown
to the City's existing water treatment plant site and expansion of that
facility would bring this water into the City's water distribution
system and to its customers.
Both the existing configuration of the City's strong water supply
system in the northern area of Round Rock and the future probabilities
of bringing additional surface water supplies to bear at this point
dictate this location as the City's best opportunity to provide
additional water supplies to not only the proposed Fern Bluff M.U.D.
but also to neighboring Brushy Creek. Improvements necessary to
provide water service to the proposed District as well as augment the
existing supplies of the Brushy Creek development have been presented
to the City of Round Rock in a study entitled "West Round Rock Proposed
Water and Wastewater Service Area Improvements" dated October 1984 and
prepared by Haynie & Kallman, Inc. Necessary improvements to achieve
this include expansions to the Round Rock water treatment plant and
appurtenances, extensions of water transmission facilities from Brushy
Creek and Fern Bluff to Round Rock's plant, and additional water
storage facilities to be located within the developments themselves.
WASTEWATER SERVICE ALTERNATIVE EVALUATION
There are possible alternatives available to serve the proposed
District with wastewater treatment and disposal service. These include
constructing their own wastewater treatment plant to serve the
anticipated residents, planning the District in such a way as to
promote the use of on -site treatment and disposal systems such as
septic systems, contracting with an existing treatment facility to
dispose of the District's waste or becomming a participant in the
proposed Brushy Creek regional wastewater transportation and treatment
system currently proposed by the Brushy Creek WC &ID.
Construct a Private Treatment Facility
To construct a new private wastewater treatment facility to serve
the residents of the District would require a permit to dispose of
waste from the Texas Department of Water Resources as well as the

actual facility itself. A proposed waterway discharge permit to
Segment 1244 would most certainly face opposition from downstream
landowners, including the City of Round Rock. There is currently a
concerted effort to regionalize wastewater treatment in the Brushy
Creek watershed and all proposed discharge permits within the proposed
service area are being challenged by the City. It is also possible
that a moritorium may be placed on new or increased discharges to this
segment of Brushy Creek until the issue of a regional plant can be
resolved. A private treatment plant to serve the District is certainly
feasible, however, in light of the fact that there is another major
discharger located adjacent to the tract (Williamson County M.U.D. No.
2) and the ongoing controversy as to the probability of contamination
of the Edwards underground aquifer by creeks such as Brushy Creek
passing over its recharge zone, the probabilty of sucessfully obtaining
a discharge permit is very low.
One alternative to discharge to a watercourse is to irrigate crops
or pasture with the treated effluent. The District could pursue this
option in two different approaches. The first one is to actually
purchase or use presently owned land as the irrigation area and operate
the system themselves. The second is to contract with neighboring
farmers and ranchers to dispose of a pre- determined amount of effluent
per year. The second method is less costly in terms of initial outlay
but requires more legal services and is less dependable because
effluent recipients are required to contract for the life of the
treatment facility.
On -site treatment and disposal systems such as septic tanks and
leach fields would not be a practical alternative for wastewater
treatment. This is mainly due to the fact that lot sizes necessary to
provide adequate drain fields for septic systems are too large to make
the development economically feasible in this area. In addition,
existing soil conditions do not lend themselves to these types of
disposal due to the severe constraints attributed to the generally
shallow depth of fractured limestone bedrock. According to the Soil
Survey of Travis County, Texas compiled and published by the United
States Department Of Agriculture Soil Conservation Service, limitations
for septic systems constructed in Eckrant and Georgetown series soils
are "severe" due to the shallow depth to bedrock. For these reasons,
on -site septic systems are discouraged.

On -Site Water Improvements
The interior water system of the proposed District network will
consist of 6 through 24 -inch water mains, gate valves, fire hydrants,
and all other necessary appurtenances (see FIGURE 3). The system will
be designed to meet City of Austin, Round Rock and State Health
Department standards and specifications. Master meters will be located
strategically to measure the District's water use. The construction
costs of these improvements are shown in more detail in TABLE 7.
On -Site Wastewater Collection System
The internal wastewater system will consist of 8 -inch through
12 -inch gravity sewer lines, manholes, lift stations, force mains and
all other necessary appurtenances required to meet City of Austin and
City of Round Rock standards as well as State Health Department
standards and specifications (see FIGURE 4). TABLE 7 shows anticipated
costs associated with development of these planned land uses using
recent bid information for similar projects.
proposed Drainage Facility Improvements
The drainage improvements in Fern Bluff Municipal Utility District
will consist of 18 -inch through 36 -inch R.C.P. Cl. III storm sewer
pipe, concrete inlets and open drainage channels (see FIGURE 5)
designed according to City of Austin, Round Rock and Williamson County
standards and specifications. These storm sewer pipes will be directed
to discharge into existing and proposed drainage ways at a controlled
rate which flow into the existing Brushy Creek drainage basin. The
overall drainage network will be designed to carry the projected
100 -year storm and all house slabs within the District will be a
minimum of one foot above the projected 100 -year storm flow. TABLE No.
7 shows the anticipated costs associated with these improvements.
The 100 year floodplain has been determined using detailed HEC - II
computer simulations. The HEC -II computer model was originally
developed by the U.S. Army Corps of Engineers for more precise
determination of watershed runoff. These simulations were modeled
using an in -house WANG 2200 computer and HEC -II software marketed by
Klagge/Stevens and Assoc., Inc. The 100 -year floodplain, as determined
by HEC -II simulation is depicted on FIGURE 5. All channelized runoff
will be contained within designated easements and all structures will
be constructed with slab elevations at least one foot above the
100 -year floodplain.

Detention facilities will be provided in accordance with the City
of Austin's drainage and detention requirements. All runoff from the
site will be routed and detained with a controlled discharge not to
exceed that of the site in its natural state. These facilites are will
be designed to contain the projected 25 and 100 -year storm runoff
flows

SECTTON X - PROPOSED OFF -SITE IMPROVEMENTS
Off -Site Water Improvements
Expansions to Round Rock's water treatment plant include a total
expansion of 12 mgd to the facility itself. This could be phased in two 6
mgd expansions since the current facility is designed to be expanded as
such. Also, additional raw water intake pumping would have to be added at
Lake Georgetown along with additional storage and booster pumping
improvements at the existing plant site. Since these are improvements to
an existing facility, owned and operated by the City of Round Rock, it is
anticipated that improvements to these facilities would be made by, owned
and operated by Round Rock.
Proposed water transmission improvements would consist mainly of
participation in the construction of a 30 -inch water extension from the
existing water treatment plant site westward to the two developments. As
shown in FIGURE 6, this line is proposed to originate at the plant site,
follow I.H. 35 south to its planned intersection with the extension of
F.M. 1431, then turn west along F.M. 1431 right -of -way to its intersection
with Great Oaks Drive in Brushy Creek North. From there it would extend
southward along Great Oaks Drive across Brushy Creek and into both Brushy
Creek South and Fern Bluff. FIGURE 6 also shows numerous additional
distribution lines and looping waterline improvements which are propoWd
under this project. The 30 -inch line would have a capacity of about
11,000 gpm (15.84 mgd).
Storage improvements to serve Fern Bluff include participation in a
1,500,000 elevated water storage tank in Fern Bluff. The proposed tank in
Fern Bluff would be a water service level 2 tank (based upon Round Rock
water service level criteria) with a 971 foot msl overflow elevation.
TABLE NO. 8 summarizes the previously mentioned proposed water
improvements in terms of gpm and L.U.E. capacities, areas served, area
demands and excess capacities if any, which will serve Fern Bluff as well
as the Brushy Creek development and the City of Round Rock. Based on the
prorated capacities of the proposed improvements as shown in TABLE NO. 8,
the estimated costs have also been prorated among the Brushy Creek and
Fern Bluff developments in TABLE NO. 8. Costs associated with excess
capacity in the improvements has been assigned to the City of Round Rock
in that table.
In addition to the obvious benefits to the future residents of Fern
Bluff, the proposed improvements would provide excess capacity for the
City of Round Rock. This excess capacity would enable the City to serve
additional connections within water service levels 2 and 3. The proposed
30" transmission main would provide enough excess delivery capacity to

serve 2,107 L.U.E.'s, while the 0.5 and 1.5 million gallon water storage
tanks will provide excess storage capacity for the City to serve 2,036 and
2,490 L.U.E.'s respectively.
Off -Site Wastewater Improvements
The Brushy Creek WC &ID regional study calls for construction of a
regional size interceptor to be constructed up Brushy Creek to tie into a
proposed regional wastewater treatment plant located east of Round Rock at
the confluence of Chandler and Brushy Creek (see FIGURE 7). The total
estimated cost of the project is $43,543,000 and it will serve
approximately 36,000 L.U.E.'s. This equates to a cost per L.U.E. of
approximately $1,300. It is currently proposed that the Brushy Creek
WC &ID own and operate the overall collection and treatment system and
contract out to the various existing entities within the watershed for
service. In the case of Fern Bluff, since Fern Bluff is not currently a
water district but is located within the proposed service area for the
City of Round Rock, the City of Round Rock would contract directly with
the WC &ID for wastewater service and then sell that service to Fern Bluff.
The time table for construction of the improvements proposed by the
W.C.I.D. call for the initial 2.5 mgd phase of the wastewater treatment
plant, interim lift station and wastewater interceptor line connection to
be in operation in approximately 18 months. The ultimate size interceptor
up Brushy Creek and the remainder of the wastewater treatment plant (total
of 10 mgd capacity) would be on line in approximately 36 months. If the
development of Fern Bluff were accelerated during that 18 month period, it
could receive initial service by pumping and removal of wastewater flow
from the site on a temporary basis for a short time between flows
beginning and the initial phase of the wC &ID system coming on line. The
cost for wastewater service under the Brushy Creek WC &ID regional plan is
outlined in TABLE NO. 9.

SECTION XT - JUSTIFICATION FOR CREATION
The Fern Bluff Municipal Utility District is viable from an
engineering and economic viewpoint. The topography does not limit
development, utilities are available and the projected construction
costs are not prohibitive.
Based on housing market projections for the District (see
ATTACHMENT - MARKET STUDY) and the general growth and economic
development of the area, it is the opinion of the Engineer for the
project that the District should be created, thereby providing housing
with water and wastewater service to this expanding area.
