Summary
Every accessory dwelling unit in the City of Kyle's Plum Creek Planned Unit Development needs its own water and sewer tap, priced the same as a primary home's tap, plus separate water and wastewater impact fees. Chapter 53A of the Kyle City Code requires at least a half living unit equivalent (LUE) of water and a half LUE of wastewater capacity for each unit.
(D) A separate water and sewer tap shall be obtained for each accessory dwelling unit. The cost of each such separate tap for accessory units shall be the same cost as a water or sewer tap for the primary single-family dwelling unit. Impact fees for both water and wastewater shall be paid and LUEs issued for each such accessory unit as required by ordinance. Not less than one-half of a water LUE and one-half of a wastewater LUE shall be required for each accessory unit; and the number, or fraction thereof, of an LUE required shall be as provided in schedule A. LUEs shall be counted and credited as they are allocated, whether in whole numbers or in fractions thereof.
Full Breakdown
Section 3(B)(7)(a)(vi)(D) of the Plum Creek PUD zoning ordinance, Chapter 53A of the Kyle City Code adopted by Ordinance No. 311 on July 22, 1997, requires a separate water and sewer tap for each accessory dwelling unit, charged at the same cost as the tap for the primary single-family dwelling on the lot. Both water and wastewater impact fees must be paid for the accessory unit, and living unit equivalents (LUEs) must be issued for it as required by the city's impact fee ordinance. The section sets a floor of not less than one-half of a water LUE and one-half of a wastewater LUE per accessory unit, with the exact fraction driven by Schedule A to the same section: units from zero to 699 square feet require a minimum 0.50 LUE, units from 700 to 849 square feet are charged at 0.50 LUE, and units from 850 up to the 1,000-square-foot maximum are charged at 0.75 LUE.
LUEs are tracked and credited in whole numbers or fractions as they are allocated, and each ADU's LUE draw also counts against the overall LUE cap for the Plum Creek PUD and for the specific platted subdivision, so a subdivision that is already near its allocated capacity may not have room left for additional accessory units.
Violations & Fines
Building a Plum Creek accessory dwelling unit without paying its separate water and wastewater impact fees and obtaining its own utility tap blocks water service connection and can trigger a stop-work or code compliance order. Beyond the utility fee itself, noncompliance with the Plum Creek PUD ordinance falls under the Kyle Code's general penalty, Section 1-14, up to $2,000.00 per day for zoning violations.
