R-85-709 - 4/25/1985WHEREAS, the City Council has previously approved the execution of an agreement entitled "Memorandum of Understanding on Williamson County Municipal Utility District No. 3 Waste Discharge Permit Amendment," and WHEREAS, due to a change in the circumstances and the schedule for construction, the City and MUD No. 3 wish to amend said Memorandum of Understanding, Now Therefore BE IT RESOLVED BY THE COUNCIL OF THE CITY OF ROUND ROCK, TEXAS That the Mayor is hereby authorized and directed to execute on behalf of the City an amendment to the aforesaid Memorandum of Understanding, a copy of said amendment being attached hereto and incorporated herein for all purposes. RESOLVED this 25th day of April, 1985. ATTEST: D9CITYD NE LAND, City Secretary RESOLUTION NO. 7 MIKE ROBINSON, Mayor City of Round Rock, Texas PD15F4 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. -2- ATTEST: EXECUTED this Joanne Land, City Secretary ATTEST: Secretary day of , 1985. CITY OF ROUND ROCK BY: WILLIAMSON COUNTY MUNICIPAL UTILITY DISTRICT NO. 3 BY: -3- Mike Robinson, Mayor W.G. Jenkins, President 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 -2- wastewater service needs of the present and future wastewater customers of the MUD. Original Facility (existing) First Expansion (existing) Second Expansion Third Expansion -3- Incremental Capacity (gpd avg.) 150,000 100,000 150,000 350,000 Cumulative Capacity (gpd avg.) 150,000 250,000 400,000 750,000 (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.

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 Austin -Round Rock area. 2 SPRINGS JOLLY VILLE Haynie & Kallman, Inc. CONSULTING ENGINEERS Austin, Texas 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 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. 4 1 1 1 1 1 1 1 1 1 1 1 r 1 1 1 1 1 1 1 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. 6 ,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 7 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 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. 8 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 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. 9 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). TABLE NO. 1 AREA PROPERTY TAX COMPARTSONS School Districts Round Rock I.S.D. M.U.D. Districts Williamson Co.

($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. 1 1 r 1 1 1 1 1 1 1 1 1 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.

The term D.U.E.'s in TABLE No. 3 refers to 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.

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 16 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 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 17 1 1 1 1 1 1 1 1 1 On -Site treatment And Disposal 1 1 1 1 1 1 1 1 1 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. Service From Existing Facilities Wastewater service for the proposed Fern Bluff Municipal Utility District could theoretically be achieved by contracting with the existing Williamson County M.U.D.

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. 20 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 21 kz \\ _ \ ' 1 L!/ ) / / - - -.— 1 / 1 / - � . // single fartuly r l /`-,`. i I t \ \/ _ detached I / / ' - - - - --1 / ample famly . , 1 / ( s / saa..., *,''l ( i —� \, \ \ . i� I L I L s ..1. famdy \ L :)) n f j JI —1 • Angle family detached gN ShY duplex I y r♦ .A t r PROPOSED 12 D.I.

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.

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.

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. 32 SECTION XII - BOND ISSUE SUMMARY 33 1 1 1 1 1 1 1 1 I NON- CONSTRUCTION COST 1.
