BE IT ORDAINED BY THE CITY COUNCIL OF THE CITY OF WYLIE A HOME RULE POLITICAL SUBDIVISION OF THE STATE OF TEXAS ; SECTION 1 . GENERAL The City of Wylie is hereby empowered to establish, define and amend sanitary sewer lift station districts for the provision of sanitary sewage collection for the current city limits and future expansion within the city ' s extraterritorial jurisdiction . These lift station districts shall be provided when , in the opinion of the City Council , they are necessary in order to promote the health , safety and welfare of the citizens of Wylie and those people impacted by such decisions within Wylie ' s extraterritorial jurisdiction . These districts shall be established in such a fashion as to make maximum use of existing topographic drainage basins and to provide for a minimum number of eventual lift stations to serve the needs of the city and it ' s ETJ . Districts may be created encompassing land that lies both within the city limits and outside the city limits at the time the district is created . This is necessary in order to insure for proper future planning and maximum utilization . Fees that may be prescribed for a particular district will be collected at the time of development based upon the level of development . Subsequent fees may be charged if eventual development exceeds the initial paid for scope of development . Land area within the ETJ will be assumed to be part of a particular lift station district and fees from such areas shall be due at the time service and annexation is requested . All lift station districts shall be established , unless specifically noted in the creation of such districts , to be based upon a gravity flow system to the city ' s lift station . Developers and individuals desiring to connect to the system shall pay their established fee for the district in which their property is designated . The payment of this fee shall entitle the developer/individual to connect to the existing system at an anticipated flow determined by the development and the payment of the fee . The monies thus collected shall go to the construction , placement , engineering and general provision of the lift station facility and it ' s necessary appurtenances . The developer/individual may , in addition, be required to extend a connecting line between his property and the available connection point . Such extension shall be at his own expense and separate from the collection of the lift station fee or any other fee . In addition , some developer/individual may be required to pay the cost of continuing through their property a general collection line for the purposes of routing the sewage to the lift station complex . The city shall keep accurate records of all monies collected and expended for each lift station district . Such monies shall be audited annually as part of the city ' s regular audit procedure . The city may use money collected from one district to start , upgrade or complete the lift station in another district in order to respond to a changing development pattern . In such case , 2 those monies shall be returned to the original lift station district account upon collection as a result of ultimate development . SECTION 2 - RUSH CREEK LIFT STATION DISTRICT NO. 1 A . There is hereby created a special district for the purposes of providing sanitary sewage facilities and the construction of a lift station . This district shall be known and referred to as the "Rush Creek Lift Station District No . 1" . B . The boundaries of the Rush Creek Lift Station District No . 1 are established as follows : Beginning at the intersection of Akin Lane and Stone Road proceed easterly to the intersection of Kreymer Lane ; Then proceed northerly along Kreymer Lane past State Highway 78 along an imaginary line extended due north of the intersection of Kreymer Lane and State Highway 78 to a point where that line intersects the existing Santa Fe Railroad right of way and rail line ; Thence from that point westerly along the Santa Fe Railroad line to the intersection of Eubanks and county road 383 ; Then continue westerly along 383 to the intersection of 383 and Paul Wilson Road ; From that point due south and along the western property boundaries of the North Texas Municipal Water District to a point intersecting the NTMWD property line and Brown Street ; From that point proceed due east along Brown Street across State Highway 78 to the eastern boundary of the Oaks Subdivision ; From that point , due south to the intersection of Rush Creek ; Thence along Rush Creek in a southwesterly direction to the intersection of Akin Lane ; Thence due south along Akin Lane to the point of beginning at Akin Lane and Stone Road an area of approximately seven hundred ( 700) acres , all of which is included in the Rush Creek Lift Station District No . l . Borders of the above described district may be amended in order to facilitate the extension of services or to exclude service to a particular parcel of property contained within the above mentioned area . Such additions or deletions may be accomplished by amending the boundary line or by specific notation as to the property or properties added or deleted . 1 . Additions to original district . a . None 2 . Deletions to original district . a . ',one C . FEE FOR DISTRICT 3 The estimated cost of providing a lift station for the Rush Creek Lift Station District No . 1 is $300 ,000 .00 . This estimate is based on 1984 dollars and therefore , the city will retain any interest earned or overages collected in order to defray any cost of inflation . This estimated cost divided by the anticipated normal density of four (4) units per acre results in a per unit fee at the time of connection of $110 . 00 per dwelling unit . Subsequent development after initial connection will be required to pay additional fees relative to increased usage . Commercial users will be charged equivalent dwelling unit fees based on an anticipated generation or subsequent production of two hundred thirty ( 230) gallons of sewage per day average . This calculation shall be made in the same manner as outlined in the City of Wylie Impact Fee ordinance and shall use the same tables and schedules for computation . SECTION 3 — PENALTY Any person , firm , corporation or other entity who is found guilty of violating the terms of this ordinance shall be deemed guilty of a misdemeanor and upon conviction of any such violation , shall be subject to a fine of not less than $1 . 00 nor more than $200 . 00 .
