This property is located north of the intersection of FM 1378 and FM 3412 (Brown Street) and more specifically described as being 87,781 acres out of the J.C. McUlmurry Survey,Abstract No. 629. Background Owner/Developer Myran Corporation, of Dallas, is proposing a housing development consisting of 359 lots (total) to be constructed on 87.781 acres of land. The original Preliminary Plat of Newport Harbor consisted of three phases. Only the first phase was ever approved as a Final Plat and approved for construction. This first phase consists of the lots presently located on Schooner Bay and Anchor Drive. The Final Plat is for Phase II, consisting of 71 lots. This new proposal contains some changes in design from the original plat, and as such, must be evaluated on its own merits. On November 4, 1996, the Planning and Zoning Commission recommended approval of the Newport Harbor Preliminary Plat. The City Council approved the same Preliminary Plat at their meeting on November 12, 1996. With the recommendation for approval by the Planning and Zoning Commission, and if City Council approves, the developer will then be allowed to begin construction of the public facilities to be dedicated to the City. Board Recommendations On January 20, 1997 the P&Z moved to recommend approval of the final plat by a vote of 7-0. Financial Considerations N/A Consent Agenda Item No 2 Page 1 Legal Considerations According to the City of Wylie's Subdivision Regulations, a Preliminary Plat must be submitted and reviewed by Staff to ensure that sufficient information exists, and is then recommended for approval by the Engineer. The Preliminary Plat and Plat Application are then submitted at least 15 consecutive days before the meeting of the Planning and Zoning Commission for its study and recommendation. The Planning and Zoning Commission shall endeavor to act on the Preliminary Plat within 30 days from the date the plat was filed with each body for their approval. The Preliminary Plat shall then be submitted to the City Council for final action. After approval of the Preliminary Plat by the City Council, the subdivider may then prepare a Final Plat of all or a portion of the land included in the Preliminary Plat for submission to and consideration by the Planning and Zoning Commission for final recommendations. Upon final action by the Planning and Zoning Commission on any Final Plat, the same shall be referred to the City Council for Final Plat approval. Upon approval action of the City Council, the Mayor is authorized to sign the signature block "Approved for Construction". At this time, the developer shall pay his required Developmental Inspection Fees and begin construction of the public facilities to be dedicated to the City. These construction areas include public streets, alleys, water lines, sewer lines, storm drainage lines, channels and all associated construction to be dedicated to the City. The City Council's vote that the Final Plat as presented is approved for construction indicates that at that point in time, no known conditions exist which will require changes from the approved Final Plat. Inspections will be made throughout the construction of the infrastructure facilities which are intended for dedication to the City. After completion of the "dedicated improvements", the developer shall apply to the City Council for acceptance of the Final Plat, which includes dedications and easements. City Staff shall indicate to the City Council that all public improvements have been completed in accordance with the requirements of the City of Wylie. Only then is the Mayor authorized to sign the signature block "Accepted". The Final Plat shall then be filed with the appropriate County, and issuance of building permits may begin. Building Permits may only be issued on a completed development or within a completed, approved phase. Staff Recommendations This Plat has been reviewed by City Staff and Consulting Engineer, Greg MacLean and meets all City of Wylie Subdivision Regulation requirements. Staff recommends approval for construction for the Newport Harbor, Phase II Subdivision Final Plat. Consent Agenda Item No 2 Page 2 Attachments Plat Application Final Plat copy 'Yr ',Lt.

Background The Water and Waste Water Master Plan Update is a document which projects the size and general location of the water mains and sewer mains required to serve the ultimate projected service area of the City's utility system. Greg MacLean of the Hogan Corporation gave the City Council a presentation on the Water and Waste Water Master Plan Update at the January 14, 1997 City Council Meeting. The Water and Waste Water Master Plan shows the sizes and locations of various mains, storage facilities, treatment plants, pumps, and lift stations based on the City's current and ultimate projected area and population. As the City grows, its current and projected ultimate service area and population may change, making it necessary to update the Water and Waste Water Master Plan to reflect the current projections. Examples of the type of changes that can occur to the Master Plan are the addition of a future elevated storage tank, water main, and a sewer main in the area that was recently annexed north of McMillen Road. This Update to the Master Plan was developed using the Land Use Assumptions which the Impact Fee Advisory Committee revised for the next ten years. The Assumptions and the Master Plan Updates were used to develop the 10-Year Capital Improvements Program(CIP) which will be recommended to the City Council for public hearing and consideration for adoption. Impact Fees will be recalculated using the new CIP and, after public hearing, may be adopted. Board Recommendations No recommendation from the Impact Fee Advisory Committee is required. The Impact Fee Advisory Committee has recommended approval of the Land Use Assumptions 1997-2006. Council will consider Agenda item 4 to set a date of March 11, 1997 for the Public Hearing to consider the 10 year CIP and Impact Fees. The Impact Fee Advisory Committee reviewed the Water and Waste Water Master Plan Update as part of the evaluation of the CIP and Impact Fees. The Water and Waste Water Master Plan is a planning document that outlines the water and sewer systems of the City at an ultimate build out, fully constructed state. Consent Agenda Item No 3 Page 1 As a planning document, it is only reviewed by the Impact Fee Advisory Committee as a basis for upgrading the CIP. The CIP can then be updated to reflect any changes that may have been made in the Water Waste Water Master Plan Update and to insure that the projects match the Master Plan. The CIP is developed and impact fees are then calculated from the costs of those projects. Financial planning is done on the basis of the CIP. Financial Considerations From a financial perspective, the Plan establishes the planning basis upon which assumptions for short and long term financing, utility rates, and Impact Fees are developed. The Land Use Assumptions used in developing the Plan provides data on population growth and patterns which can be used to create utility revenue forecasts. The Plan also provides data on future capital expenditures which will have to be taken into consideration for short and long term financing. Legal Considerations Section 395.014 of the Local Government Code allows cities to prepare a CIP and to adopt Impact Fees. The Water and Waste Water Master Plan is a tool used to assist in the development of the CIP. Staff Recommendations Staff recommends adoption of the Water and Waste Water Master Plan Update.

Background In November of 1996, the Impact Fee Advisory Committee (IFAC) was appointed for the purpose of reviewing and possibly amending the Impact Fees the City charges for new development. The IFAC reviewed and updated the 1997-2006 Land Use Assumptions. The City Council will conduct a Public Hearing and consider adopting those Assumptions on January 28,1997. A series of meetings were held by the IFAC to review the Water and Waste Water Master Plan Update and 10-year Capital Improvements Program (1997- 2006)(CIP). The IFAC, in their final meeting on January 16, 1997, took action and recommended to City Council to adopt the CIP and recognized the Maximum Calculated Impact Fees figured from that CIP. By State law, the City must set a date for the Public Hearing more than 30 days, but not more than 60 days, before that Hearing is to be held. The action necessary tonight is to set that date for the March 11, 1997 City Council meeting. In the weeks to come, staff will be compiling data for the Council to have available prior to that meeting. Information that will be forthcoming is a matrix showing Impact Fee reconciliation and how optional funding in lieu of Impact Fees will affect bond purchases or other funding. A comparison of Impact Fees charged by other cities will be available. Figures will also be made available relating to the possibility of operating two waste water treatment plants (our current facility and a scaled down version of a new facility) and details of our operating permit and State guidelines that cause the necessity to begin planning a new facility. Development assumptions regarding the number of new dwellings calculated according to the new 1997-2006 Land Use Assumptions will also be supplied. Consent Agenda Item No 4 Page 1 Board Recommendations The Impact Fee Advisory Committee recommends adopting the 10-year Capital Improvements Program (1997-2006) and recognizes the Maximum Calculated Impact Fees at $1,412 for sewer and $700 for water with a total of$2,112 maximum. Financial Considerations N/A at this time. Legal Considerations The Texas Local Government Code, Section 395 establishes the City's authority to establish or amend Impact Fees. Notice of the Public Hearing must be published once a week for three consecutive weeks in a paper of general circulation in the counties where the City lies. The first notice will appear before the 30th day but on or after the 60th day before the date set for the hearing. The notice of public hearing may not be in the part of the paper in which legal notices and classified ads appear and may not be smaller than one-quarter page of a standard-size or tabloid-size newspaper, and the headline on the notice must be in 18-point or larger type. The notice must contain: (1)A headline to read as follows: "NOTICE OF PUBLIC HEARING ON ADOPTION OF IMPACT FEES"; (2) the time, date, and location of the hearing; (3) a statement that the purpose of the hearing is to consider the adoption of an impact fee; (4) an easily understandable map of the service area on which the proposed fee will be levied; (5) the amount of the proposed impact fee per LUE; (6) a statement that any member of the public has the right to appear at the hearing and present evidence for or against the plan and the proposed fee. Staff Recommendations Staff recommends setting a date for the Public Hearing on the adoption of the 10-Year Capital Improvements Program(1997-2006) and Impact Fees for the March 11,1997 City Council Meeting. Attachments N/A Prepared by Re e by Fina e City M ager Approval Consent Agenda Item No 4 Page 2 WYLIE CITY COUNCIL ACTION AGENDA COMMUNICATION ITEM NO 5 January 28, 1997 Issue Hold a Public Hearing and Consider for Adoption a Resolution Approving the Land Use Assumptions, 1997-2006. Background Chapter 395 of the Texas Local Government Code details the process by which cities in the State must formulate development impact fees. Land Use Assumptions are used to help the City in determining the need and timing of capital improvements caused by future development. Information pertaining to the type, location, quantity, and timing of various type of land uses is contained in these Assumptions. These Land Use Assumptions will then be used to formulate the updated 10-Year Capital Improvements Program(CIP) from which the revised Impact Fees will be calculated. Public Hearings are required on these Land Use Assumptions and on the subsequent CIP and Impact Fees. The Land Use Assumptions have four main components: A Service Area Map, which shows the proposed service area for water and waste water systems; Base Data, information on existing use and population as of December 1996; Land use and growth assumptions for the next 10 years; and the ultimate built-out condition of the service area. Several factors are used in considering these projections. They include character, type, density, and quantity of existing development, existing zoning patterns, future land uses, availability of land for expansion, physical holding capacity of the City, and location and configuration of vacant land. Existing land uses were updated from the information contained in the Assumptions from 1990. This was done by adding the number of building permits issued since 1990 for dwellings to the number of existing dwellings at that time. Densities were calculated at 2.9 persons per household for low and medium densities and 2.0 per household for high density units. This, added to the 1990 population, gave an estimated population of 11,698 persons. Ultimate projections were then considered so that the 10-year growth assumptions would not surpass the development potential of the service area. Action Agenda Item No 5 Page 1 Land use was based on the Comprehensive Plan's Future Land Use Map. Vacant land was classified by its individual land use categories on the Future Land Use Map and added to the existing acreage in the same uses. Generally, future land uses were considered developed according to the Future Land Use Map(with recorded zone changes noted). These future land uses were assumed to have similar characteristics as the current existing acreage with the same land use classification. The maximum population was then calculated using acreage of low, medium, and high density dwelling units and the number of persons per unit for each type of development. The population estimate was 57,324 persons for residential land use projections. Having established an existing and projected ultimate population, the Impact Fee Advisory Committee discussed several population projections. The Committee selected a graduated projected growth rate of 3.5% for the first three years, 5% for the next three years, and 7% for the last four years. Using those rates, the population was estimated at 19,680 in the year 2006. This rate was selected mainly because the Committee believed that the widening of Hwy. 78 south to access the 190 corridor and the widening of F.M. 544 to the west would prompt development on an increasing percentage as these projects became realities. Board Recommendations The Impact Fee Advisory Committee recommends adopting the Land Use Assumptions 1997-2006 based on the population increases of 3.5% for the first three years, 5% for the next three years, and 7% for the next four years. Financial Considerations N/A Legal Considerations Section 395.042-395.045 of the Texas Local Government Code detail the rules for adopting Land Use Assumptions associated with the adoption of Impact Fees. The proper notice for a public hearing was published in the newspaper in accordance with the requirements. The public hearing must be held before the City Council can adopt the Land Use Assumptions by resolution.

Y . CITY OF WYLIE LAND USE ASSUMPTIONS PURPOSE Chapter 395 (formerly Senate Bill 36) of the Texas Local Government Code prescribes the process by which cities in Texas must formulate development impact fees. To assist the City of Wylie in determining the need and timing of capital improvements to serve future development, a reasonable estimation of future growth is required. For the purposes of determining an impact fee structure, growth and development projections were formulated based on assumptions pertaining to the type, location, quantity and time of various future land uses in the community. It is the purpose of this report to document the methodology used for preparing the growth and land use assumptions for the • City of Wylie's impact fee service area. These assumptions will become the basis for the preparation of impact fee capital improvement plans for water and wastewater facilities. METHODOLOGY This report contains four major components: • 1. Service Area Map- Map showing the proposed service area for water and wastewater impact fees,which is the preponderance of the area within the present City Limits, and a minor part of the City's extraterritorial jurisdictional area 2. Base Data- Information on existing land use and population for Wylie as of December, 1996 3. Land use and growth assumptions for 10 years (to the year 2006) for area delineated by the Service Area Map 4. Ultimate or"holding capacity" projections for the service area which reflects a built-oyt condition based on the City's approved Future Land Use Plan These land use assumptions and future growth projections take into consideration several factors influencing development patterns, including: 1. The character, type, density and quantity of existing development 2. Existing zoning patterns 3. Future land use plans 4. Availability of land for future expansion 5. Physical holding capacity of the City for land uses and population 6. Location and configuration of vacant land Based on the growth assumptions and the capital improvements needed to support growth, it is possible to develop an impact fee structure which allocates improvement costs in a fair manner to developing areas in relationship to their impact on the entire infrastructure system. The following base data and projections have been formulated using reasonable and generally accepted planning principals. SERVICE AREA MAP Plate 1 depicts the service area, which includes most of the area within the corporate limits of Wylie and a portion of the City's extraterritorial jurisdiction (ETJ) area. All of the data collection and projections are formulated for this service area. A capital improvement plan will be prepared separately for water facilities and for wastewater facilities, and the geographic boundaries of the service area will be the same for each element in the plan. BASE DATA In any evaluation and projection of future land use patterns, a thorough understanding of existing conditions is essential. Within the context of this study, a documentation of existing land use patterns and population was critical to determine a base line for future growth projections. To obtain accurate land use information on existing conditions, a field survey was conducted in • February, 1990 by City personnel. This information was updated to the end of 1996 by permit and zone change records. From that survey and subsequent update, each parcel in the City was classified according to its use in one of the following land use categories: Category General Description for Use of Land 1. Residential a. Single-Family Detached dwelling located on a lot or tract b. Duplex A two-family dwelling located on a lot or tract c. Mobile Home A manufactured home either in a park or on a separate lot d. Multi-Family A structure housing three or more family units e. Townhome Attached single-family structure 2. Nonresidential a. Retail Business offering goods for sale including offices b. Commercial A service oriented business occasionally with outside storage or light fabrication c. Industrial The manufacturing of a product involving possible open storage, noise, odor or smoke emission d. Public/Semi Public Uses which give membership such as churches, schools and lodges e. Park and Open Space Public space devoted to recreation f. Railroad Land used in railroad right-of-way. g. Right-of-Way Land used in public right-of-way h. Vacant/Agriculture Land used for urban purposes, found to be vacant or used for agricultural purposes Each of the above categories were tabulated on a parcel-by-parcel bases and recorded for the service area. Table 1 shows a summary of existing land uses for the service area as of December, 1996. The total area within the service area is 10,126.0 acres. Of this total area, 24.16 percent is developed as represented by the sum of all developed uses in 2,446.7 acres. The graphic presentation for existing land use patterns is shown for the service area and surrounding areas in the City's extraterritorial jurisdiction by the Existing Land Use map in the Appendix.

At that time there were 3,499 dwellings comprised of single-family detached, two-family, mobile home, multi-family and townhouse units. Since that time there have been 959 building permits for single-family dwellings issued. This would now bring the total estimated dwelling units in existence to 4,458. Subtracting the vacant units and using an estimated average household size of 2.9 for low and medium density units and 2.0 for high density units, the existing population is estimated to be 11,698 persons. Household sizes of 2.9 for low and medium density units and 2.0 for high density units are derived from census data for this area. The relationship of land use to population is shown by Table 2, as a ratio of land per 100 persons in the existing population.

Land use was projected based upon the uses proposed by the Future Land Use Plan. Acreages now vacant were calculated by individual land use categories shown on the Land Use Plan. These acres were added to similar acres of existing land use to provide a total acreage for each of the land use categories. Areas which cannot be developed due to their flood prone location were recognized but calculated into the acreage of the adjoining use. It was assumed that the ultimate projections would result in a 100% occupancy of land although there can be expected some vacant land, and in relationship to the City's size,this amount would be negligible. Ultimate land use projections were based primarily on the land use and intensity recommendations in the City's Land Use Plan. The following assumptions were used in preparing the ultimate land use projections: 1. Future land uses would be built-out at the same or similar intensity as existing development of the same type. 2. Residential density is currently approximately 4.5 dwelling units per acre, not including streets and alleys. This ratio can be expected to remain fairly constant as the community matures. 3. Future office development would be generally two stories with an average floor area ratio of .3 to .4. 4. Retail would develop at a floor area ratio of.25. Commercial uses would develop at a floor area ratio of.2. 5. Future land uses would consume land and have general boundaries as set forth on the Future Land Use Plan as shown by the Plan in the Appendix. As calculated,there would be general net acreages of 1,308.8 industry, 441.3 commercial with 390.2 acres of retail. For the purposes of this study Railroad use would not change (there is a possibility that it will in the future). Public and semi-public would have schools and parks, making up the preponderance of this category. Rights-of-way would be at the accepted average found in most communities of 25.0% when built out. Approximately 4,397.4 acres would be available for low and medium density and 261.8 acres available for high density residential. ULTIMATE LAND USE PROJECTION The land use projections for total development is shown in Table 3. This allocation of street right-of- • way in the amount of 25% of the total area was removed from each land use category. Therefore, values shown in Table 3 are considered to be net developable acres. TABLE 3 LAND USE -FOR ULTIMATE DEVELOPMENT PROJECTIONS WYLIE,TEXAS Category Acres Residential, Low 8, Med. Density 4,397.4 Residential, High Density 261.8 Public and Semi-Public 678.2 Retail 390.2 Commercial 441.3 Railroad 155.9 Industry 1,308.8 Street Rights-of-Way 2,492.4 Total Developed 10,126 POPULATION HOLDING CAPACITY PROJECTION The above land use projections estimate approximately 4,397.4 acres of land will be used for low and medium density residential use. The estimated number of residential building sites will range between 4.0 and 5.0 per acre. For purposes of estimating single-family detached population, a factor of 4.5 is used. High density allocation is 261.8 acres and can be expected to develop at a minimum of 15 units per acre. The following summarizes the estimated dwelling unit projections: Low and Medium Density-4,397.4 acres-4.5units/acre = 19,788 units High Density- 261.8 acres- 15.0 units/acre = 3,927 units Total Units- 23,715 units Future population will be dependent upon the number of future dwelling units/households and the number of persons per unit/household. The above calculations estimate the total units, or households as used herein. Population per household has been declining and such decline is expected to continue in the future, reaching 2.0 to 2.2. For purposes of estimated population holding capacity for Wylie, a factor of 2.5 is used for low and medium, indicating a larger than average future household size for detached units and a factor of 2.0 for high density. The population estimate using these factors is 57,324 persons for the residential land use projections. TEN-YEAR LAND USE ASSUMPTIONS Having established the existing and projected ultimate conditions in Wylie, a ten-year growth projection for land use and population was formulated. Several population projections were discussed between members of the Impact Fee Advisory Committee. Over a ten-year period, the proposed growth rate selected by the Committee was a graduated growth rate of 3.5% for the first 3 years, 5% for the next 3 years and 7% for the last 4 years. This rate represents a moderate to accelerated growth throughout the decade. Using the rate discussed above, an estimated population of 19,680 persons in the year 2006. The following shows the required land uses (marginal increase) for this growth rate compared to the actual amount in 1996. The marginal increase is that acreage in addition to the existing acreage used in 1996. For the selected growth rate,the increase is 7,982 persons. TABLE 4 REQUIRED FUTURE LAND(ACRES) FOR YEAR 2006 Existing Additional Acres for Acres Population of 7,982 1,035.2 Residential 706 290.8 Public and Semi-Public 199 119.3 Parks and Open Space 81 38.3 Retail and Office 26 162.7 Commercial 111 155.9 Railroad 0 77.7 Industrial 53 566.8 Street/Alley Rights of Way 386 and Parking 2,446.7 1,562 The marginal increase in population (gain between 1997 and 2006) is shown below for the selected graduated population growth rate. Graduated Growth Rate (3.5%, 5%, 7%) Total Population (year 2006) 19,680 Net Dwelling Units Increase (1997-2006) 2,328 Marginal Population Increase (1997-2006) 7,982 The year 2006 population projection of 19,680 persons is estimated to have 2.9 persons per dwelling unit. This value calculates the total number of residential units for the year 2006 to be 6,786 which is 2,328 units greater than the existing calculation of 4,458 units. It is recommended that the City use the selected graduated growth rate (3.5%, 5%, 7%) for the calculation of impact fees within the service area. The Impact Fee Advisory Committee considers this rate to be viable for the City between 1997 and 2006. The growth of 7,982 persons between 1997 and 2006 for the area within the service area can be reasonably expected to occur if growth begins to build for the remainder of the decade. This growth would represent a medium to fast increase in population and land use absorption.
