In recent years, the increasing population and economic development of North Central Texas have led to growing demands for water supplies. At the same time, local and less expensive sources of water supply are largely already developed. Additional supplies to meet future demands will be expensive and difficult to secure. Severe drought conditions in recent years have highlighted the importance of the efficient use of our existing supplies to make them last as long as possible. Extending current supplies will delay the need for new supplies, minimize the environmental impacts associated with developing new supplies, and delay the high cost of additional water supply development. Recognizing the need for efficient use of existing water supplies, the Texas Commission on Environmental Quality (TCEQ) has developed guidelines and requirements governing the development of water conservation plans. The City of Southlake has developed this water conservation plan in accordance with TCEQ guidelines and requirements. To develop a regional approach, Tarrant Regional Water District's and City of Fort Worth's Water Conservation and Drought Contingency Plan, of whom the City of Southlake is a customer, were consulted. This Water Conservation Plan replaces the previous plan dated March 2009. In addition, the City of Southlake developed this water conservation plan with guidance from the City of Southlake Water Conservation Master Plan (Master Plan), an element of the Southlake 2030 Comprehensive Plan, a copy of which is provided in Appendix C. The Master Plan was adopted by Southlake City Council on April 16, 2013 after careful consideration from the public, council members, and staff. This water conservation plan includes goals identified in the Master Plan. The City of Southlake recognizes that in order to achieve its goals of maximizing water conservation and efficiency, it is necessary to develop and implement a water conservation plan that goes beyond basic compliance with TCEQ guidelines and requirements. This plan reflects the City of Southlake's commitment to enhanced water conservation and efficiency strategies. The objectives of this Water Conservation Plan are as follows: • To reduce water consumption from the levels that would prevail without conservation efforts; • To reduce the loss and waste of water; • To improve efficiency in the use of water; • Encourage efficient outdoor water use; • And, to extend the life of current water supplies by reducing the rate of growth in demand. The city's plan will achieve significant conservation savings to help extend the life of existing supplies without burdening the customer with unnecessary additional costs. 1 2.0 TEXAS COMMISSION ON ENVIRONMENTAL QUALITY RULES 2.1 TCEQ RULES GOVERNING CONSERVATION PLANS The TCEQ rules governing development of water conservation plans for public water suppliers are contained in Title 30, Part 1, Chapter 288, Subchapter A, Rule 288.2 of the Texas Administrative Code. For the purpose of these rules, a water conservation plan is defined as "A strategy or combination of strategies for reducing the volume of water withdrawn from a water supply source, for reducing the loss or waste of water, for maintaining or improving the efficiency in the use of water, for increasing the recycling and reuse of water, and for preventing the pollution of water." The elements in the TCEQ water conservation rules covered in this conservation plan are listed below. 2.1.1 MINIMUM CONSERVATION PLAN REQUIREMENTS The minimum requirements in the Texas Administrative Code for Water Conservation Plans for Public Water Suppliers are covered in this report as follows: • 288.2(a)(1)(A) - Utility Profiles - Section 3.0 and Appendix B • 288.2(a)(1)(B) - Record Management System - Section 5.2 • 288.2(a)(1)(C) - Specific, Quantified Goals - Section 4.0 • 288.2(a)(1)(D) - Accurate Metering - Section 5.2 • 288.2(a)(1)(E) - Universal Metering - Section 5.2 • 288.2(a)(1)(F) - Determination and Control of Water Loss - Section 5.2 and 5.3 • 288.2(a)(1)(G) - Public Education and Information Program - Section 6.1 • 288.2(a)(1)(H) - Non - Promotional Water Rate Structure - Section 6.2 • 288.2(a)(1)(J) - Means of Implementation and Enforcement - Section 6.3 • 288.2(a)(1)(K) - Coordination with Regional Water Planning Group - Section 6.4 and Appendix D • 288.2(c) - Review and Update of Plan - Section 8.0 2.1.2 CONSERVATION ADDITIONAL REQUIREMENTS (POPULATION OVER 5,000) The Texas Administrative Code includes additional requirements for water conservation plans for drinking water supplies serving a population over 5,000: • 288.2(a)(2)(A) - Leak Detection, Repair, and Water Loss Accounting - Section 5.3 • 288.2(a)(2)(B) - Wholesale Water Supply Contract Conservation Measures - Fort Worth Wholesale Water Contract 2.1.3 ADDITIONAL CONSERVATION STRATEGIES The Texas Administrative Code lists additional conservation strategies, which may be adopted by suppliers but are not required. Additional strategies adopted by the City of Southlake include the following: • 288.2(a)(3)(A) - Conservation Oriented Water Rates - Section 6.2 and 7.2.1 • 288.2(a)(3)(B) - Ordinances, Plumbing Codes or Rules on Water- Conserving Fixtures - Section 7.1.3 and 7.2.6 2 • 288.2(a)(3)(D) — Reuse and /or Recycling of Wastewater and /or Greywater — Section 7.3.4 • 288.2(a)(3)(1) — Considerations for Landscape Water Management Regulations — Section 7.1 2.2 GUIDANCE AND METHODOLOGY FOR REPORTING ON WATER CONSERVATION AND WATER USE In addition to TCEQ rules regarding water conservation, this plan also incorporates elements of the Guidance and Methodology for Reporting on Water Conservation and Water Use developed by TWDB and TCEQ, in consultation with the Water Conservation Advisory Council (Guidance). The Guidance was developed in response to a charge by the 82nd Texas Legislature to develop water use and calculation methodology and guidance for preparation of water use reports and water conservation plans in accordance with TCEQ rules. The City of Southlake has considered elements of the Guidance in preparation of this Plan. 3 3.0 DESCRIPTION OF SERVICE AREA AND UTILITY PROFILE The City of Southlake provides retail water and sewer service to approximately 27,500 residents (2014 population estimate).

The goals for this water conservation plan include the following: • Maintain the 5 -year moving average total per capita water use below specified amount in Table 4 -1. • Maintain the level of water loss in the system below the specified amount in Table 5 -2. • Maintain a program of universal metering and meter replacement and repair as discussed in Section 5.2. • Increase efficient water usage and decrease waste in lawn irrigation by enforcement of landscape water management regulations as described in Section 7.1. • Raise public awareness of water conservation and encourage responsible public behavior by a public education and information program as discussed in Section 6.1. In the previous (2009) plan, total per capita use goals were 190 gpcd by 2015 and 180 gpcd by 2020 As of 2014, Southlake's five year average per capita use was 351 gpcd. The previous goal set for Southlake did not account for Southlake's typical water use, but rather was an adoption of the Region C goal. As such, the 2020 and 2025 goals have been revised to reflect more realistic goals based on current water use. Southlake will use the suggested 1% reduction in gpcd, per the Fort Worth Water Conservation Plan (Section 4.0). The current specific goals are outlined in Table 4 -1. These goals were developed assuming a five year average per capita, and therefore some dry years will see higher per capita usage than these five year average goals. A series of dry years may lead to an average exceeding the goal. TABLE 4 -1: GPCD GOALS (2014) Description 2013 2020 2025 Total GPCD 333 327 311 Residential GPCD 238 231 221 a. Total GPCD = (Total Gallons in System _ Permanent Population) _ 365 b. Residential GPCD = (Gallons Used for Residential Use + Residential Population) - 365 4.1 ANALYSIS OF BEST MANAGEMENT PRACTICES During each update of the Water Conservation Plan the city has evaluated the Best Management Practices (BMPs) outlined in the Water Conservation Best Management Practices Guide. In addition, the City of Southlake has evaluated BMPs through the adoption of the Water Conservation Master Plan, as previously discussed in Section 1.0 of this plan. For a complete analysis of the BMPs, refer to Tables 4 -2 and 4 -3 on the following pages. Table 4 -2 is the implementation schedule of the BMPs for the practices the city has implemented and the proposed implementation date for additional strategies. Table 4 -3 lists BMPs with a quantifiable potential savings in 2020 and 2025, the proposed cost in 2020 and 2025, and the cost per thousand gallons. 7 TABLE 4 -2: WATER CONSERVATION BEST MANAGEMENT PRACTICES IMPLEMENTATION SCHEDULE BMP Description Currently Implemented Implemented Implemented Implemented before 2015 before 2020 before 2025 System Water Audit and 5.3 Water Loss Nossf 6.1.1 Youth Education Residential Consumer 6.1.2 Education Nif Licensed Trade Educational 6.1.3 Outreach Property 6.1.4 Management /Owner V Outreach 6.1.5 Partnerships with Water Conserving Agencies 6.1.6 Develop a Landscape Guide Nif Twice Per Week Watering 7.1.2 Schedule Prohibition on Wasting 7.1.2 Water NI 7.1.3 Irrigation Permitting and NI, Review Inspection Program 7.2.1 Water Conservation Pricing 7.2.2 Water Conservation Coordinator 7.2.3 10 -Year Meter Replacement V 7.2.4 Weather Information for Lawn Irrigation Nor 7.2.5 Identify and Monitor Water Wells for Impact on Municipal System 7.2.6 Plumbing Codes al Review Codes 7.2.7 Municipal Water V Conservation Policy 7.2.8 Smart Meter Technology 7.3.1, Landscape Irrigation 7.3.2 Conservation and Incentives Water Consumption Impact 7.3.3 Analysis 7.3.4 Rainwater N Harvesting /G raywate r 8 TABLE 4 -3: BEST MANAGEMENT PRACTICE COST- EFFECTIVENESS ESTIMATES Annual Impact MGD Savings Cost / 1000 Gallons BMP Description (Est.)

Programs for universal metering, meter testing, meter repair, and periodic meter replacement have been developed using American Water Works Association (AWWA) standards and are important elements in the City of Southlake's program to control losses. 5.1 PRACTICES TO MEASURE AND ACCOUNT FOR THE AMOUNT OF WATER DIVERTED FROM THE CITY OF FORT WORTH Water delivered from the City of Fort Worth is metered both where it leaves the City of Ft Worth and six (6) miles away where it enters the City of Southlake with technology no older than 2012. This allows better leak detection in the delivery lines. 5.2 MONITORING AND RECORD MANAGEMENT PROGRAM FOR DETERIMINING DELIVERIES, SALES, AND LOSSES The city has an effective record management system in place. As required by by TAC Title 30, Part 1, Chapter 288, Subchapter A, Rule 288.2 (a)(2)(B), Southlake's record management system allows for the separation of water sales and uses into residential, commercial, municipal, and industrial categories. This information is included in the TCEQ required Water Conservation Implementation report, as described in Section 6.3. 5.2.1 METERING ALL NEW CONNECTIONS AND RETROFIT OF EXISTING CONNECTIONS The city meters all connections in the distribution system. Meters range in size from 3/4" to 8 ". The meter size distribution is included in Table 5 -1 below. All meters meet AWWA accuracy standards when installed. TABLE 5 - 1: METER SIZE DISTRIBUTION Meter Size Total 3/4" 610 1" 7,107 2" 817 3" 60 4" 79 6" 17 8" 2 5.3 LEAK DETECTION, REPAIR AND WATER LOSS ACCOUNTING The system water audit is used annually to monitor the total level of non - revenue water. There are many variables which influence the revenue and non - revenue components of the city's water system including meter inaccuracy, data discrepancies, unauthorized consumption, reported breaks and leaks and unreported losses. This BMP corresponds to WC -10 of the Master Plan. 10 The City of Southlake uses gallons per connection per day as its preferred water loss metric as it is less variable than other metrics to climatic conditions. The five -year average water loss (gallons per connection per day) was 25 GPCD or an average of 7%, as described in Section E of the Utility Profile (Appendix B). The city will continue to track water losses throughout the system by analyzing and updating the targets and goals of this section annually in conjunction with the water audit. Because the City of Southlake continues to measure a low water loss volume and percentage, the city will commit to maintaining the current water loss volume and percentage as a moving average through 2025, as shown in Table 5 -2. TABLE 5 -2: WATER LOSS GOALS (2014) Description Units 5 yr avg 2020 2025 Water Loss GPCD GPCD 25 25 25 Water Loss Percentage % 7 7 7 6.0 OTHER REQUIRED CONSERVATION MEASURES 6.1 PUBLIC EDUCATION AND INFORMATION Developing a strategy for providing water conservation information to the general public is an effective means of both promoting specific water conservation programs and practices and educating the public about the importance of using water efficiently. Programs will be tailored to the community and the audience it is being delivered to. In Southlake, a focus on the residential water customer should be one of the target audiences due to residential nature of the community. Developing an outreach program to residents, business owners, property managers, HOA's and others whose decisions may influence water use at a residential or commercial property will also help to raise awareness about water conserving techniques and technologies and encourage the decision makers to choose best practices. The city has identified the following Public Education BMPs to be implemented during this 5 -year plan. 6.1.1 SCHOOL /YOUTH EDUCATIONAL PROGRAM The city will develop a program focused on educating the city's youth in partnership with local school districts, private schools and other youth oriented organizations. Programs should focus on awareness about water use and how to adopt water conserving habits. This BMP corresponds to WC -1 of the Master Plan. 6.1.2 RESIDENTIAL CONSUMER EDUCATIONAL PROGRAM The city will develop a program for targeting residential consumers through various means such as websites, media, direct mailings, personal contact, etc. These programs will focus on residential water use, especially landscape water use, and how residents can take action to reduce water use. This BMP corresponds to WC -2 of the Master Plan. 11 6.1.3 LICENSED IRRIGATORS AND CONSTRUCTION TRADE EDUCATIONAL OUTREACH PROGRAMS The city will partner, when possible, with other entities to develop or strengthen outreach programs to licensed irrigators, plumbers, and other construction trades that may influence water use. These type of programs will focus on the newest technologies and practices. This BMP corresponds to WC -3 of the Master Plan. 6.1.4 BUSINESS AND PROPERTY OWNER /MANAGER RELATIONS PROGRAM Often property owners and managers can make influential decisions about water use at commercial and institutional properties. The city will develop a relationship with property owners and managers, provide educational opportunities and assist property owners and managers in making decisions to reduce water use. This BMP corresponds to WC -4 of the Master Plan. 6.1.5 CONTINUE TO SEEK PARTNERSHIPS WITH AGENCIES TO PROMOTE WATER CONSERVATION The city will continue to seek and take advantage of partnerships with local entities such as Fort Worth and Tarrant Regional Water District to promote water conservation on a regional scale. This BMP corresponds to WC -5 of the Master Plan. 6.1.6 DEVELOP A LANDSCAPE GUIDE FOR THE GENERAL PUBLIC AND LANDSCAPE PROFESSIONALS The city will work with landscaping professionals and regional entities to develop guidance for the general public and landscape professionals. This guide will focus on landscaping that promotes water conserving techniques. This BMP corresponds to WC -6 of the Master Plan. 6.2 WATER RATE STRUCTURE The City of Southlake has a conservation - oriented water rate structures in place. The city's current rate structure consists of either a residential, commercial, or HOA class. Usage charges are assessed according to customer class and meter size. An increasing block rate structure is in place for all classes to encourage water conservation. The city analyzes each customer class and sets rates in proportion to those classes which place the most demands upon the water system. The rates shown in Appendix E were effective as of January 1, 2014 and are subject to change as the city continues to refine its rate structures to improve the impact on water conservation and manage the cost of service most effectively. 6.3 IMPLEMENTATION AND ENFORCEMENT The City of Southlake completes the TCEQ required Water Conservation Implementation Report by the 1 of May each year. The report includes various water conservation strategies that have been implemented, including the date of implementation. Additionally, the report includes progress made on the five and ten year per capita water use goals from this Plan. If the goals are not being met, Southlake must document why not. The amount of water saved is also documented in this report. 12 6.4 COORDINATION WITH REGIONAL WATER PLANNING GROUPS The city has been working with Fort Worth and Tarrant Regional Water District, who in turn have been working with the local Regional Water Planning Groups (Region C and G), to help develop the water conservation plan documents. Copies of the Water Conservation Plan will be sent to the Chairs of the Region C Water Planning Group, The City of Fort Worth, and the Tarrant Regional Water District. 13 7.0 ADDITIONAL CONSERVATION EFFORTS 7.1 LANDSCAPE WATER MANAGEMENT 7.1.1 PREVIOUSLY ADOPTED PROHIBITIONS AND ENFORCEMENT MEASURES The city has adopted ordinances that prohibit a number of water wasting activities. Prohibitions include: • Watering between the hours of 10 am and 6 pm, when wind and solar evaporation is greatest; • Watering during a rain event or a freeze event; commercial properties and new irrigation systems are required to install a rain /freeze sensor on automatic sprinkler systems and owners of existing residential systems are encouraged to install a rain /freeze sensor; • Causing water waste through such as activities as irrigating directly onto paved surfaces or operating a system with broken equipment. 7.1.2 ADOPT LAWN AND LANDSCAPE IRRIGATION RESTRICTIONS The following lawn and landscape irrigation restrictions are hereby adopted per ordinance 895 -C. (a) Except for hand watering, drip irrigation and the use of soaker hoses, a person may only irrigate, water, or cause or permit the irrigation or watering of any lawn or landscape located on premises owned, leased, or managed by that person (i) on a day designated as an outdoor water use day for the property's address as shown below; and (ii) between the hours of 12 midnight to 10 a.m. and 6 p.m. to 12 midnight.

(c) A person commits an offense if he knowingly or recklessly irrigates, waters, or causes or permits the irrigation or watering of a lawn or landscape located on premises owned, leased or managed by the person in a manner that causes: 14 (1) a substantial amount of water to fall upon impervious areas instead of a lawn or landscape, such that a constant stream of water overflows from the lawn or landscape onto a street or other drainage area; or (2) an irrigation system or other lawn or landscape watering device to operate during any form of precipitation. (d) A person commits an offense if, on premises owned, leased, or managed by that person, a person operates a lawn or landscape irrigation system or device that: (1) has any broken or missing sprinkler head; or (2) has not been properly maintained in a manner that prevents the waste of water. (e) Affirmative Defenses (1) It shall be an affirmative defense to prosecution of an offense in (a) that at the time such person irrigates, waters, or causes or permits the irrigation or watering of any lawn or landscape, such activity was for the purpose of: i. establishing hydromulch, grass sod, or grass seed; ii. dust control of a sports field; or iii. for the maintenance, repair, or testing of an irrigation system. (2) Such activity described in Subsection (d)(1) may be an affirmative defense to prosecution only if the activity occurred for a period of thirty consecutive days or less. After the thirtieth consecutive day of such activity, a person who irrigates, waters, or causes or permits the irrigation or watering of any lawn or landscape in violation of this section shall be subject to administrative fees and criminal penalties. (f) It shall be an exception to prosecution of an offense in this section, if a person who irrigates, waters, or causes or permits the irrigation or watering does so by use of an alternative water source such as a well, reclaimed or reused water, or water from the Trinity River if that person has: (1) Registered such alternative water source with the city; (2) Provided sufficient proof to the director that the alternative water source is from a well, reclaimed or reused water or from the Trinity River and has allowed inspection by the director if deemed necessary; and (3) Complied with the city's Backflow and Cross - Connection Control Program. 7.1.3 REGULATE INSTALLATION OF IRRIGATION SYSTEMS The city actively enforces TCEQ rules on irrigation installation, including the requirement that a licensed irrigator install or make major repairs to an irrigation system. The city accepts and reviews irrigation plans, per TCEQ rules. In addition, the city has adopted code specific to increasing the efficiency of new irrigation systems, including a requirement that all new spray heads and rotors include pressure regulation. This decreases over - pressurization at the spray head and reduces water waste. In the next few years the city will review the permitting and inspection processes. This review will include a focus on an effective process on ensuring a new system is highly efficient. This BMP corresponds to WC -15 of the Master Plan. 15 7.2 MUNICIPAL BEST MANAGEMENT PRACTICES 7.2.1 CONDUCT WATER RATE STUDY — WATER CONSERVATION PRICING Water Conservation Pricing is the use of rate structures that discourage the inefficient use of or the waste of water. Conservation pricing structures include increasing unit prices with increased consumption such as inverted block rates, base rates and excess use rates such as water budget rates, and seasonal rates. While the city has already established a water conserving pricing structure, the city will conduct a study of current the non - promotional water rates to insure the efficacy of the rate structure. This BMP corresponds to WC -7 of the Master Plan. 7.2.2 EMPLOY A FULL -TIME WATER CONSERVATION COORDINATOR A common element in successful conservation programs is a conservation coordinator who is responsible for implementing and maintaining the conservation program. This person would be responsible for preparing and implementing the city's water conservation and drought contingency plans, prepare and submit the annual conservation status reports, and implement the utility's conservation program. The city has identified a water conservation coordinator as important in fully implementing the elements of this plan. This BMP corresponds to WC -8 of the Master Plan. 7.2.3 METER REPLACEMENT AND TESTING An efficient metering system raises a customer's awareness of the true amount of water the customer is consuming, which can help the customer make changes to his or her habits. The city implemented a meter exchange program six years ago that provides for the annual replacement of 10% of the city's meters each year. Large meters not included in the annual replacement program are tested and repaired or replaced annually. The master meters measuring total volume of water delivered to the city were replaced 3 years ago and are tested annually. This BMP corresponds to WC -9 of the Master Plan. 7.2.4 UTILIZE WEATHER STATIONS TO PROVIDE OUTDOOR IRRIGATION INFORMATION Currently, the city utilizes weather stations at the Community Services' parks to provide outdoor irrigations system. In the near future, the city will take advantage of a program to be offered by Tarrant Regional Water District. TRWD is developing an interactive weather station program to install weather stations throughout its service area to provide consumers with a weekly e-mail and information through a website in determining an adequate amount of supplemental water that is needed to maintain healthy grass in specific locations. This service will provide the public advanced information regarding outdoor irrigation needs, thereby reducing water use. Through a series of selections on the type of irrigation system a consumer has, a weekly email that will tell the customer how long (in minutes) an irrigation system needs to run based on the past seven days of weather. This recommendation provides the actual amount of supplemental water that is required for a healthy lawn based on research of the Texas A &M Agrilife Extension Service and proven technologies. Southlake will promote this program, encourage its retail and wholesale customers to participate in the program, and make the information available through its website. This BMP corresponds to WC -11 of the Master Plan. 16 7.2.5 WELL WATER Many of Southlake's water customers utilize groundwater as a source. More than 65% of well water applications have indicated the groundwater is used for irrigation purposes. The relationship between self - reliant well water users and municipally provided water arises when wells dry up, pumps fail, or for other reasons property owners choose to utilize municipal water. This potential demand is unaccounted for and the city has identified the need to monitor the water table of potential customers and to maintain an inventory of existing water wells. This BMP corresponds to WC -12 and WC -13 of the Master Plan. 7.2.6 PERIODICALLY REVIEW WATER CONSERVING ORDINANCES The city has adopted a number of water conserving policies in building codes, including the 2012 residential code, 2012 plumbing code, and 2012 energy code. As discussed in section 7.1.3 the city has adopted landscape irrigation code that promotes water conserving features. Because technology frequently changes, codes should reflect technological advancements and policy should reflect changes in attitudes. The city will review plumbing codes on a frequency of once every five years to identify relevant changes that promote further water conservation. This BMP corresponds to WC -14 of the Master Plan. 7.2.7 DEVELOP A MUNICIPAL WATER CONSERVATION POLICY The city will implement a policy of adopting water conserving features, where possible. Replacement at older facilities water fixtures will be of more efficient fixtures. Implementing the replacement of older building water fixtures such as toilets, urinals, lavatory faucets, irrigation, cooling towers and water brooms with higher efficiency water fixtures will help reduce the water consumption in these buildings that are consistently occupied. Also, performing water audits at existing park facilities on the existing landscape irrigation systems and installing high efficiency upgrades would help reduce consumption. This BMP corresponds to WC -15 of the Master Plan. 7.2.8 UTILIZE SMART METERS New technology known as smart meters or Advanced Metering Infrastructure (AMI) has the potential to change the way water consumption is measured. Southlake has been using electronic -read meter technology. The city is in the process of converting to totally electronic meters which will provide customer interface through smart -phone apps and desktop software to promote customer awareness and tool for detecting household leaks and water waste. This BMP corresponds to WC -17 and WC -18 of the Master Plan. 7.3 CONSERVATION PROGRAMS FOR RESIDENTIAL, INDUSTRIAL, COMMERCIAL, AND INSTITUTIONAL ACCOUNTS 7.3.1 RESIDENTIAL IRRIGATION SYSTEM EVALUATION AND REPAIR REBATE PROGRAM The city currently contracts with a vendor to promote water conserving techniques in existing landscape irrigation systems. The vendor evaluates the irrigation system for leaks, breaks, misalignments, and other issues that create inefficiencies. The city follows up by offering a rebate to the homeowner to offset the cost of repairs and changes to the system to make it more efficient. Since this program started 17 in 2010, the average homeowner has saved 26,800 gallons of water each summer. This BMP corresponds to WC -19 of the Master Plan. 7.3.2 COMMERCIAL AND INSTITUTIONAL IRRIGATION EVALUATION AND REPAIR REBATE PROGRAM The city will expand the program described in section 7.3.1 to offer irrigation evaluations and repair rebates to commercial and institutional customers. This BMP corresponds to WC -22 of the Master Plan. 7.3.3 WATER CONSUMPTION IMPACT ANALYSIS To help determine how new development will impact the water system, the city will require certain developments to complete a consumption impact analysis. This impact analysis will help the city assess water use as the city reaches a built -out phase. This BMP corresponds to WC -20 of the Master Plan. 7.3.4 RAINWATER HARVESTING AND GRAYWATER USE Residential harvesting and condensate reuse and graywater use are potential alternative water supplies. Large properties with the potential to utilize these alternative non - potable uses for landscaping irrigation can help conserve municipally - supplied sources. The city will seek out a cost - effective measure to encourage the use of these alternative sources. This BMP corresponds to WC -21 of the Master Plan. 18 8.0 ADOPTION OF WATER CONSERVATION PLAN; PERIODIC REVIEW AND UPDATE OF PLAN All of the BMPs in this plan were selected for the City of Southlake through the adoption of the Master Plan. Opportunity for public comment on the master plan was provided as described in Section 1.0. Opportunity for public comment on this plan is provided at a City of Southlake City Council Meetings on April 1, 2014 for the first reading of Ordinance 895 -C and on April 15, 2014 for the second reading and public hearing after which this Water Conservation Plan was adopted. TCEQ requires that water conservation plans be reviewed and, if necessary, updated every five years to coincide with the regional water planning process. This Water Conservation Plan will be updated as required by TCEQ and, in addition, will be continually reassessed for opportunities to improve water efficiency and conservation based on new or updated information. 19 Appendix A: Ordinance 895 -C Adopting this Water Conservation Plan Appendix B: City of Southlake Utility Profile Based on TCEQ Format Texas Water Utility Profile Development Board TWDB Form No. 1965 - R Revised on: 9/1/13 UTILITY PROFILE FOR RETAIL WATER SUPPLIER Fill out this form as completely as possible.

Stage 1 drought restrictions went into effect after total storage capacity in our reservoirs reached 75 %. The restrictions were in effect from Aug. 29, 2011 — May 4, 2012. Southlake implemented water restriction based on local triggers meant to protect the supply system due to high IL demands.

The similarity to annual use indicates, as programs. expected, that water use per account is highly driven by the amount of water use in the summer months. 2.2 Managing Water Demand Peaks Because water use is viewed as largely irrigation driven, it can be One of the biggest challenges a water provider can face is peaks (or expected that lots with large acreage will use much more water, spikes) in demand that strain the capacity of the system. Managing especially during the growing season. these peaks is difficult, even when the water system is well - developed. Similar to building a highway to manage peak rush -hour traffic, a water 2005-2012 provider must anticipate the peak demand and build a system to 4,945 deliver that peak demand. 11,541 12.602 The City of Southlake is contractually bound to our wholesale water 13,190 4 supplier, the of Fort Worth a 13307 = pp City to pay peaking charges and adhere to ®,3,;zs drought contingency plans and conservation requirements, such as the su 13.493 -. adopted Drought Contingency Plan shown in Appendix B of this plan. 13,667 These contract provisions are designed to help manage these water 14.196 4 demand peaks. In extreme cases, failure to do so can result in loss of 14 pressure in the system requiring customers to boil water before using 16,669 it, and /or simply running out of water. These scenarios pose public 11 health and safety risks, including creating a situation where there is not adequate fire flow available to extinguish a fire. In Southlake, these peaks occur during the heat of the summer and are driven by water use for irrigation. Irrigation uses during the summer months can account for more than 60% of the total water demand. AVERAGE WATER USE PER SPIN DURING THE SUMMER MONTHS (JUNE- AUGUST) In addition to the challenges these peak pose in development and However, do Southlake residents use more water because residents management of the infrastructure, the peak demand fees paid to the have more land to irrigate?

There were several criteria used in evaluating the consumer directly, but rather recommendations developed for this master plan. With the goals and to maintain the quality of life objectives of the plan in mind, the City developed four areas that each for the consumer with recommendation should be evaluated against when determining its minimal changes for the day - priority. The four areas consisted of: to -day life. This should 4411°- 'a; continue making the City an ➢ Cost Effectiveness attractive place for residents f `. ➢ Estimated Water Savings as well as for businesses. • Relevance to Local Conditions; and Challenges to Implementation Due to the nature of this master plan being oriented These four areas were assessed on each recommendation, and if they towards having a significant were considered high or strong in an area this assisted the education & outreach component, the cost effectiveness of such recommendation with being ranked on higher priority, or Tier, as recommendations can be assumed to be high. Many of the other discussed in Section 3.5 of this master plan. These next few sections recommendations within the municipal and residential /commercial will be focused on discussing the four areas evaluated. categories should be studied for cost effectiveness prior to implementation. 4.1 Cost effectiveness 4.2 Estimated water savings The first area that was looked into when the City identified water conservation recommendations in this master plan was the cost The next area evaluated was the estimated water savings of each effectiveness of the recommendation, policy or program. While it recommendation. This area, just as cost effectiveness, can be difficult should be noted that all the programs, policies and improvements to assess due to some of the same reasons. The consumers or target being recommended in this plan will cost the City money to some level, audience the recommendation, policy or program is directed towards it should not be forgotten that the purpose of this plan is to ultimately may have different results from community to community so some create a sustainable community in terms of its water consumption. The assumptions are difficult to make and therefore may require further financial impacts should be minimal when compared to the cost of analysis. continuing the status quo of water consumption in the City. The Ordinance No. 1061, Adopted April 16, 2013 [SOUTHLAKE 2030] 24 [SOUTHLAKE 2030] Water Conservation Master Plan The same type of rationale was applied to discretionary user and reducing their overall consumption, the greater this area when it was evaluated against or higher priority was placed on the recommendation. It was also the recommendations. For example, the critical to take into account the prevalence of larger lot sizes and estimated water savings of the City abundance of swimming pools that the typical consumer has in the implementing a sustainable landscape City. ordinance, that for instance may require *.a , 75% of the landscape area of any development to have drought tolerant plantings will likely be greater than •• y:rf auditing the City's water system for water " ` t c 6 �R ; }. a • z �`•• loss. The estimated water savings is likely �' • greater creating an ordinance that y,� implements the use of drought tolerant plantings requiring less water t $xw rather than performing a water system audit that doesn't modify any behaviors immediately. 4.3 Relevance to Local Conditions The next issue considered was the relevance to Southlake's local , y , conditions. As mentioned in Section 2, a vast majority of the .,,_,.•.rte, development in Southlake is newer and already has many more current �' '•` "`"� ' k water efficient fixtures such as toilets, showerheads and faucets. So when the recommendations were considered it was important to take 4.4 Challenges to Implementation into account the type of consumer in the City. The last area evaluated when considering the recommendations of this Southlake can be considered a bedroom community where most of its plan were the challenges of implementing the recommendation. This property owners and residents are both commuting and working in particular area proved to be complex because the cost effectiveness, another city, attending school, or taking care of the day to day errands estimated water savings and relevance to local conditions can be of a typical household. These types of users can be considered considered challenges in themselves. The challenges were viewed more discretionary water users. When recommendations were evaluated in the sense of, if the recommendation were to begin implementation against this area it was important to note that the consumption was today, what would those obstacles be. not by large factories or commercial processes that require large amounts of water but rather by individual discretionary water user. Thus, the more the recommendation was targeted towards the Ordinance No. 1061, Adopted April 16, 2013 [SOUTHLAKE 2030] 25 [SOUTHLAKE 2030] Water Conservation Master Plan Some of the obstacles considered in implementing the some of those programs, policies and improvements can be more recommendations in the plan were: appealing and desirable to implement immediately, when placed in a priority order and weighed against available funding, may not be • Public perception implemented in the near future. • Staff time needed to implement recommendation • Availability of funding • Ability to track and monitor effectiveness A All of these areas were considered and evaluated against every V. recommendation to better determine the priority in which the a °� recommendations should be considered. . -,, . , ' i Ii ,� l ,.) , , 1,„ . 4 - - L.------44‘ For each specific recommendation, a relative priority (Tier) has been established to assist with the priority of implementation of the recommendation. During the development of this master plan, each _ recommendation was evaluated against four areas, as outlined in the previous sections, which assisted in determining the priority of the particular program, policy or improvement. The results of this 4.5 Plan Implementation evaluation allowed City staff to assign the recommendations based on priority Tiers. The Tiers are divided into three different Tier categories A plan is only as good as its implementation. This plan will establish a based on timeframe to implement: foundation for future water conservation master plans to be built upon. Y Tier 1: 1 to 3 Years ➢ Tier 2: 4 to 7 Years There are several recommendations of programs, policies and Tier 3: 8 Years and beyond improvements that have been adopted as a part of this plan. And while Ordinance No. 1061, Adopted April 16, 2013 [SOUTHLAKE 2030] 26 [SOUTHLAKE 2030] Water Conservation Master Plan There are some policies, programs and improvements within this master plan that will require a more technical approach, generally listed as Tier 2 and Tier 3 categories. In some of these situations an evaluation, such as a cost - benefit analysis, will be necessary in order to obtain a better idea of when that policy, program or improvement will be able to be completely funded and implemented. The analysis will need to contain the expected balance of benefits and costs, including an account of foregone alternatives. This will help predict whether the benefits of a policy, program or improvement outweigh its costs, and by how much relative to other alternatives, including not implementing the recommendation. These more complex recommendations require more time and more analysis and therefore have been listed as a Tier 2 or Tier 3 recommendation. The recommendations requiring capital costs will of course be fully dependent on the outcome of the Capital Improvements Program (CIP) process. The CIP planning process begins and ends with projects recommended by this and all other master plans. Annually, as part of the City's budget process, city staff analyzes the adopted master plan and develops a comprehensive list of projects and corresponding details along with preliminary cost estimates for each project to be included in the proposed CIP. The proposed CIP is submitted to the CIP Technical Committee (department directors), who rank them based on set criteria. A priority list is then developed and forwarded to the City Manager for evaluation and approval. The priority tiers that were developed during this master plan will help guide future members of the City's boards and City Council when making decisions related to the CIP. While these tiers have provided the order of implementation and priority of which the water conservation recommendations were considered, it should be noted that all recommendations are subject to available funding during the given budget year and will be placed on the Capital Improvements Program (CIP).

This has since been serving as a reminder partnerships with the Tarrant Regional Water District, City of Fort that it is crucial for Southlake to carefully plan for its water resources, Worth and other water conservation agencies in educating water and provide an adequate and sustainable water supply to serve the consumers on the importance of water conservation in order to extend needs of its water users. To meet this goal, reduced water consumption available water supplies to future generations. through implementation of conservation policies and programs will be extremely important.

The next few sections in this plan will describe in greater detail the recommendations that resulted from the evaluation of Southlake's current utility profile, future water demands and the criteria established in Section 4.0 of this plan. The recommendations have also been broken down by category in which they are more directly applied to. 5.1 Education & Outreach Programs In the last few decades there has been a substantial increase in education and awareness programs across the country in the form of televised commercials, radio announcements, websites and other promotional material aimed at informing the public about water usage Water conservation represents a cost - effective and environmentally and its limited availability. Education and outreach is also the most cost sound way to reduce current and future water demand and energy effective measure in water conservation that should not be ignored but usage. Homeowners and business owners can take many actions to rather capitalized on, especially in today's rapid information age. reduce water use, such as using water conserving fixtures and Ordinance No. 1061, Adopted April 16, 2013 [SOUTHLAKE 2030] 28 [SOUTHLAKE 2030] Water Conservation Master Plan Educating at an early age ''"" _.
