Item 4GItem 4G Ordinance 662-D; 1st Reading; Revise Drought Contingency Plan The Texas Commission on Environmental Quality (TCEQ) Requirements Public water systems serving populations greater than 3,300 adopt: Water Conservation Plan Drought Contingency/Emergency Water Management Plan Beginning May 1, 2005 Update and reauthorize by the governing body at least once every five years Water Demand / Emergency Water Management A Drought Contingency / Emergency Water Management Plan is: a statement of a water supplier’s capacities a response plan addresses external conditions (i.e. drought, system failure) that create the need to restrict usage for the protection of health, safety and welfare of the public. Drought Contingency/Emergency Water Management Plan Southlake’s Drought Contingency Plan First adopted in August, 1996 Mirrors the Ft. Worth plan as required Two significant changes proposed “Triggers” are conditions which warrant the various stages of conservation measures to take effect Tarrant Regional Water District’s (TRWD) reservoir capacity Ft. Worth’s treatment capacity and Southlake’s storage and pumping capacity Change 1 - Plan Stages The most obvious change has no effect on existing operations Proposed Watering Schedule for Stage 1 No watering Monday & residents get a weekday and weekend watering day Proposed Watering Schedule for Stage 2 No watering Monday & Weekend day is removed from residential watering Stage Triggers TRWD, Ft. Worth and Southlake each has unique limitations that affect implementation of the Plan They also have common triggers to advance to the next stage: The water treatment or distribution system becomes contaminated The water demand for all or part of the delivery system approaches delivery capacity because delivery capacity is inadequate The water supply system is unable to deliver water due to the failure or damage of major water system components Stage 1 Triggers TRWD reservoirs drop below 75% (25% depleted) of conservation storage City of Fort Worth reaches or exceeds 90% of reliable delivery capacity for 3 consecutive days The tank level in Southlake’s elevated tanks fall below eighteen (18) feet, and continue to fall below this level, with the Pearson Road Pump Station at 100% capacity, for 3 consecutive days in either pressure plane Stage 1 Restrictions/Exceptions Restrictions: Twice per week irrigation schedule Limitations for vehicle washing Washing pavement, sidewalks, buildings etc. Exceptions: Foundation watering New landscaping with conditions and commercial nurseries Golf courses and professional sports fields Stage 2 Triggers TRWD reservoirs drop below 60% (40% depleted) of conservation storage City of Fort Worth reaches or exceeds 95% of reliable delivery capacity for three consecutive days With Stage 1 in place at least two weeks, the tank level in Southlake’s elevated tanks fall below eighteen (18) feet, and continue to fall below this level, with the Pearson Road Pump Station at 100% capacity, for three (3) consecutive days in either pressure plane Stage 2 Restrictions/Exceptions Restrictions (Stage 1 restrictions PLUS) Once per week irrigation schedule Operation of ornamental fountains Watering for dust control Exceptions Foundation watering Commercial nurseries Golf courses and professional sports fields with restrictions Stage 3 Triggers TRWD reservoirs drop below 45% (55% depleted) of conservation storage City of Fort Worth reaches or exceeds 98% of reliable delivery capacity for one day With Stage 2 in place at least two weeks, the tank level in Southlake’s elevated tanks fall below twelve (12) feet, and continue to fall below this level, with the Pearson Road Pump Station at 100% capacity, for three (3) consecutive days in either pressure plane Stage 3 Restrictions/Exceptions Restrictions (Stage 1 and 2 restrictions PLUS) No landscape watering No new landscaping Hydrant water usage except for health, safety and welfare Exceptions Foundation watering Some exemptions for tree watering Golf courses greens only and professional sports fields Variances to Water Use Restrictions The Public Works Director may grant a variance to the water use restrictions under one or more of the following conditions Failure to grant such a variance would cause an emergency condition adversely affecting health, sanitation, or fire safety for the public or the person requesting the variance Compliance with this plan cannot be accomplished due to technical or other limitations Alternative methods that achieve the same level of reduction of water use can be implemented Termination of the Stages Initiating agency has termination authority If drought induced demand causes implementation, the plan remains effective until September 30th unless weather conditions clearly change Director may terminate when the conditions which triggered the stage have subsided Questions?
