Nov 08, 2022 Special Austin Integrated Water Resource Planning Community Task Force

SO, UM, DO WE HAVE ANY PUBLIC COMMUNICATION? NO.

OKAY,

[APPROVAL OF MINUTES]

UM, AND THEN OUR FIRST ITEM IS THE APPROVAL OF THE MEETING MINUTES FROM THE SEPTEMBER 20TH TASK FORCE MEETING.

IS EVERYONE SEEING THOSE IN OUR PACKET? AND I HAD A CHANCE TO REVIEW.

THIS IS ROBERT.

I MAKE A MOTION FOR APPROVAL OF MINUTES.

WE HAVE A MOTION.

DO WE HAVE A SECOND? SOMEBODY ONLINE WILL NEED TO WAVE THEIR ARM.

SARAH.

JENNIFER, CAN Y'ALL HEAR US? YES.

CAN YOU HEAR ME? YEP, I CAN HEAR YOU.

OKAY, GOOD.

CAUSE I HAD BEEN TRYING TO SAY SOMETHING AND I WAS WORRIED.

MAYBE YOU COULDN'T HEAR ME.

WELL, THIS IS THE FIRST THING I'VE HEARD YOU SAY, SO, OKAY.

MAYBE IT WAS LIKE NOT WORKING BEFORE.

UM, I, UH, WAS JUST LETTING YOU KNOW THAT I HAD LET JANEL KNOW EARLIER, LIKE A FEW WEEKS AGO, THAT I WAS GONNA HAVE TO BE OFF AT ONE O'CLOCK, SO I DON'T AT ONE O'CLOCK.

SO MAYBE I, I'M ASSUMING WE'VE STRUCTURED EVERYTHING WHERE WE CAN VOTE ON WHAT WE NEED TO VOTE ON WHILE WE STILL HAVE A QUORUM, BUT JUST WANTED TO LET YOU KNOW THAT.

ANY DISCUSSION ON THE MINUTES? ALL IN FAVOR? AYE.

ANY OPPOSED? ANY ABSTENTIONS? OKAY.

THAT PASS PASSES.

CHECK THE OFFICIAL MARK ON MY AGENDA.

[1. Proposed 2023 Meeting Dates]

SO LET'S MOVE ON TO VOTING ITEMS, WHICH IS, UM, TAKE ACTION ON PROPOSED 2023 MEETING DATES SO WE CAN GET THAT, UM, BUSINESS TAKEN CARE OF.

AND THEN WE WILL, UM, GO BACK TO THE REGULAR AGENDA.

SO IF WE COULD TEE UP THE SLIDES FOR ITEM NUMBER SIX UNDER VOTING ITEMS. WE'RE WAITING JUST A MOMENT TO GET THAT, THOSE SLIDES ON THE SCREEN.

AND YOU CAN MOVE TO THE NEXT SLIDE.

AWESOME.

SO STAFF HAVE IDENTIFIED THESE AS PROPOSED 2023 MEETING DATES.

WE ARE AGAIN AIMING FOR HOLDING A TASK FORCE MEETING EVERY OTHER MONTH, BEGINNING IN JANUARY, IN MARCH.

YOU'LL NOTICE THAT WE, UM, RATHER THAN CHOOSING THE, UH, UH, SECOND TUESDAY OF THE MONTH, WE'VE CHOSEN A LATER TUESDAY TO TRY TO AVOID SOME VACATIONS AND HOLIDAYS ASSOCIATED WITH SPRING BREAK.

UM, WE ALSO HAVE A NOTE DOWN AT THE BOTTOM THAT WE MAY NEED AN ADDITIONAL MEETING IN APRIL TO ALIGN WITH THE DELIVERY OF OUR WATER DEMAND PROJECTIONS.

UM, BUT WE CAN TALK ABOUT THAT LATER AS A POTENTIAL FUTURE SPECIAL CALLED MEETING FOR THE REGULAR MEETING SCHEDULE.

WHAT WE'RE PROPOSING IS HERE ON THE SCREEN IS JANUARY 10TH, MARCH 28TH, MAY 9TH, JULY 11TH, SEPTEMBER 12TH, AND NOVEMBER 14TH.

SO FAR, WE'RE THINKING THAT THESE WOULD PRIMARILY BE HYBRID MEETINGS.

THE LOCATION IS YET TO BE DETERMINED IN, UH, SOME CASES, HOWEVER, THEY COULD BE EITHER AT HERE AT THE PDC OR AT THE MUELLER BUILDING.

UH, WE DO NOT HAVE ACCESS TO ROOM 1 0 4 IN WALLER CREEK CENTER YET.

WE'RE NOT ANTICIPATING HAVING ACCESS TO THAT IN 2023.

SO WE'RE PLANNING FOR OTHER LOCATIONS.

PROPOSED MEETING DATES? ALL RIGHT.

ANY, UM, OKAY.

ANY DISCUSSION ABOUT THE PROPOSED 2023 MEETING DATES? THIS IS, IS THERE, IS THERE A WAY FOR US TO SEE THE SLIDES AND THE PEOPLE, THERE'S SOME FOLKS OVER HERE MAKING THIS ALL WORK, SO THANK YOU ALL VERY MUCH.

AND THIS IS ROBERT.

I'LL MAKE A MOTION TO APPROVE THESE MEETING DATES.

WE HAVE A SECOND.

I CAN'T SEE HANDS, SO JUST SPEAK UP.

UM, TASK FORCE MEMBERS A SECOND.

THE MOTIONS, SARAH.

THANK YOU, SARAH, ANY DISCUSSION ON

[00:05:01]

ALL IN FAVOR? AYE.

AYE.

THINK THAT'S EVERYBODY.

[Items 1 & 2]

MOVING BACK UP TO, UM, UPDATE ON WATER SUPPLY CONDITIONS.

SO WE'LL BE TEEING UP THE SLIDES FOR ITEM NUMBER TWO UNDERNEATH THE DISCUSSION ITEMS HEADING, UH, MARISA? YES.

WE HAVE TWO PEOPLE THAT HAVE TO GET OFF AT ONE O'CLOCK TODAY.

AND ONE PERSON AT ONE 30 .

SO, UM, WILL WE BE ABLE TO CONTINUE ON THE NON-VOTING ITEMS AFTER WE DON'T HAVE A QUORUM ANYMORE? IN, GO AHEAD.

IF PERRY JOINS, YES, IF PERRY JOINS.

YEAH, HE SAID YOU TRY TO MAKE IT WORK.

OKAY, WONDERFUL.

AND IF PERRY DOESN'T JOIN, I DON'T BELIEVE WE CAN CARRY ON WITH THE MEETING.

SO UPDATE ON WATER SUPPLY CONDITIONS.

YOU CAN MOVE TO THE NEXT SLIDE.

UH, THIS CHART IS COURTESY OF RICHARD H POWER, OUR CONSULTING HYDROLOGIST.

IT SHOWS UPDATED HIGHLAND LAKES INFLOWS IN 2022 IN GREEN.

WE HAVE THOSE FROM JANUARY THROUGH OCTOBER.

YOU CAN SEE THAT INFLOWS IN OCTOBER WERE VERY LOW, UH, 3000, A LITTLE OVER 3000 ACRE FEET IN THE ONE MONTH.

UM, THIS WAS SOMETHING OF A MARKER FOR US.

WE WERE WAITING TO SEE WHAT OCTOBER WOULD HOLD FOR US.

WE DID SEE THAT OCTOBER WAS DRIER AND WARMER, UH, THAN AVERAGE, AND WE ANTICIPATE THAT THOSE DR.

UH, WILL LIKELY CONTINUE.

UM, CAN WE MOVE TO THE NEXT SLIDE? SO WE'VE GOT AN UPDATE ON, ALSO APPEAR TO SEE OF RICHARD.

UM, AS OF YESTERDAY, COMBINED STORAGE WAS AT 1.05, 1 MILLION ACRE FEET AT 52% FULL.

THIS IS A LITTLE BIT OUTDATED.

UH, T W D B DOES HAVE A NEW WATER WEEKLY AS OF, UH, THIS WEEK.

BUT, UM, FOR THE WEEK OF OCTOBER 31ST, IN THAT LAST WEEK, DROUGHT CONDITIONS HAD IMPROVED.

UM, IN NORTH CENTRAL TEXAS, WHILE ALONG THE COASTAL REGIONS, WE CAN SEE THAT THOSE DROUGHT CONDITIONS HAD CONTINUED TO WORSEN, UM, IN THIS WEEK'S WATER WEEKLY, UM, IN THE CENTRAL TEXAS AREA.

THE DROUGHT CONDITIONS HAVE CONTINUED, UM, AND HAVE CONTINUED TO BECOME A LITTLE WORSE.

AND THIS IS A THREE MONTH OUTLOOK FROM NOAH.

UM, WE ARE LOOKING AT ABOVE AVERAGE, UH, CHANCES OF HIGHER THAN NORMAL TEMPERATURES AND BELOW, UM, UH, AN, UH, UH, ABOUT BELOW AVERAGE CHANCES OF GETTING OUR AVERAGE SEASONAL PRECIPITATION.

TRYING TO MOVE THROUGH THIS QUICKLY SO WE CAN GET THROUGH OUR CONTENT .

ON THE CONSERVATION SIDE, AS WELL AS, UM, DROUGHT RESPONSE ACTIVITIES FOR, UM, PROGRESSIVELY, UH, UH, MORE INTENSE DROUGHT STAGES ON THE WATER SUPPLY PLANNING SIDE AS WELL.

AND THEN THIS IS THE UPDATED LCRA FORECAST OF COMBINED STORAGE THROUGH MAY, 2023.

WE CAN SEE THAT THESE LINES HAVE FLATTENED OUT A LITTLE BIT.

SO FROM LAST MONTH'S FORECAST, WE SEE A LITTLE BIT OF A LESS OPTIMISTIC FORECAST MOVING INTO THE SPRINGTIME.

UM, IN THIS FORECAST, THEY HAVE, UH, YOU KNOW, INCLUDED, UM, A, A PROJECTIONS THAT STILL STAY ABOVE 900,000 ACRE FEET, WHICH, IF YOU'LL REMEMBER, IS OUR TRIGGER FOR STAGE TWO DROUGHT CONTINGENCY PLAN IMPLEMENTATION.

UM, JUST AS A NOTE, UH, THE CLIMATE PREDICTION CENTER HAS INDICATED ABOUT A 75% CHANCE THAT WE STAY IN LEIA CONDITIONS THROUGH JANUARY THROUGH THE END OF THIS CALENDAR YEAR.

AND THERE'S A 54% CHANCE THAT WE TRANSITION TO ENZO NEUTRAL ABOUT THE FEBRUARY THROUGH APRIL TIMEFRAME.

SO THAT, UH, NOT NEC, WE'RE NOT TRANS.

THAT DOESN'T MEAN TRANSITIONING INTO EL NINO.

THAT DOESN'T MEAN TRANSITIONING INTO WET CONDITIONS.

IT JUST MEANS TRANSITIONING INTO NEUTRAL CONDITIONS, AVERAGE CONDITIONS.

SO WE ANTICIPATE WE ARE CONTINUING TO DO OUR PLANNING FOR, UM, CONTINUATION OF DROUGHT, UM, AND WHAT THAT MEANS IN TERMS OF DROUGHT RESPONSE ACTIVITIES

[00:10:01]

YEP, THAT MAKES SENSE.

UM, SO WE HAD HEARD THAT AT ONE POINT THAT THERE WAS A, A MEMO OR SOMETHING BE PREPARED FOR COUNCIL ABOUT, ABOUT DROUGHT PREPARATIONS, AND I THINK IT WAS MAYBE PRESENTED TO THE WATER OVERSIGHT COMMITTEE.

SO THERE WAS A PRESENTATION THAT WAS MADE, UH, TO THE AUSTIN WATER OVERSIGHT COMMITTEE, I BELIEVE IT WAS IN SEPTEMBER.

UM, THAT PRESENTATION WAS PROVIDED BY TERESA.

UM, AS WE CONTINUE TO MOVE THROUGH, UH, THE, THE COMING MONTHS AND WE MOVE INTO SPRING AND SUMMER WHEN WE'LL LIKELY SEE WARMER CONDITIONS AGAIN, UH, WE ARE THINKING THAT, YOU KNOW, WE'LL, WE'LL WORK ON THE TIMING OF UPDATES AND COMMUNICATIONS TO THE TASK FORCE, TO OTHER BOARDS AND COMMISSIONS, AS WELL AS COMMITTEES OF COUNCIL AND COUNCIL ON DROUGHT CONDITIONS AND WATER SUPPLY OUTLOOKS.

SO WE'RE THINKING THAT THAT COULD LOOK LIKE QUARTERLY UPDATES ON, UM, THE, UH, WATER SUPPLY OUTLOOK AND OUR ACTIVITIES, OUR DROUGHT RESPONSE ACTIVITIES.

AND THEN OF COURSE, TO THE TASK FORCE WE WOULD BE HAVING OUR, OUR BIMONTHLY UPDATES.

UM, ANY QUESTIONS FROM FOLKS OR SHOULD WE KEEP MOVING? OKAY.

SO I HAVE A QUESTION ABOUT THE AGENDA.

, UM, SINCE WE MAY BE ON QUITE LIMITED TIME HERE, UM, IS ARE THERE PARTICULAR THINGS HERE THAT STAFF HAVE PREPARED PRESENTATIONS FOR THAT WE SHOULD, WE SHOULD MOVE UP IN THE QUEUE? I WANNA BE RESPECTFUL OF FOLKS THAT HAVE DONE THAT.

I'VE SEEN SOME, SOME FOLKS HERE THAT WE MAY BE HEARING FROM.

UM, THE DECENTRALIZED RECLAIMED IS A SPECIAL, SPECIAL DEBUT FROM SOME MEMBERS OF OUR SYSTEMS PLANNING STAFF.

IF WE COULD, UH, TEE UP THE DECENTRALIZED RECLAIM PLANNING UPDATE, UM, AS A HIGHER PRIORITY ITEM, THAT WOULD BE GREAT.

AND THEN, UM, OUR STAFF HAVE ALSO PREPARED, UH, SOME SLIDES FOR THE SCENARIO PLANNING APPROACH, BUT OF COURSE WE CAN, WE CAN GET TO THAT IN OTHER MEETINGS.

[3. Decentralized Reclaimed Planning Update, presented by Austin Water staff]

EXCELLENT.

WELL, LET'S PROCEED WITH THAT AND, AND, UH, HAND IT OVER TO, UH, ITEM NUMBER FOUR, THE DECENTRALIZED RECLAIM PLANNING UPDATE.

AND WHO'S DOING THAT? THAT'S US.

EXCELLENT.

ARE, UH, OUTFITTED WITH WHAT WE CALL REMOTE WASTEWATER TREATMENT FACILITIES.

UM, I'M JOE SMITH AND THE SYSTEMS PLANNING TEAM AT AUSTIN WATER, AND I'M JOINED BY BROOKE BURHAN AND MICHELLE GARZA.

UM, WE'RE KIND OF A TEAM OF THREE IN THE SYSTEMS PLANNING DIVISION AT AUSTIN WATER WHO HAVE BEEN FOCUSED ON DECENTRALIZED RECLAIMED PLANNING.

AND WE'RE PART OF A LARGER GROUP THAT HAS BEEN CONTINUING TO PLAN FOR, UH, VARIOUS IWS INNOVATIVE WATER STRATEGIES IS THE NAME OF THE LARGER COMMITTEE THAT WE'RE ON.

AND SO WE'RE HERE TO REPRESENT KIND OF SOME WORK THAT WE'VE BEEN DOING, THIS TEAM AS WELL AS OTHERS OPERATIONS, FACILITIES, ENGINEERING, RECLAIM WATER, SEVERAL OTHER GROUPS ARE WORKING WITH US DEVELOPING THIS PLAN.

SO, UM, NEXT SLIDE PLEASE.

JUST A QUICK LITTLE AGENDA OVERVIEW.

UM, WE'RE GONNA, THIS WAS A WATER FORWARD 18 STRATEGY, AND SO WE'LL KIND OF TOUCH ON THAT A LITTLE BIT TO REMIND SOME OF YOU THAT WE'RE HERE WITH THAT.

UM, AND THOSE OF YOU WHO ARE NEW TASKFORCE MEMBERS, JUST A LITTLE BIT OF AN INTRODUCTION OR REINTRODUCTION TO WHAT IT IS WE'RE TALKING ABOUT WITH DECENTRALIZED RECLAIMED, AND THEN HOW DOES IT FIT INTO OUR OVERALL RECLAIMED WATER STRATEGY AT AUSTIN WATER.

AND THIS GROUP HAS BEEN WORKING TOWARD PREPARING UPDATES FOR THE WATER FORWARD 24 PLAN.

SO WE'LL GIVE YOU A LITTLE BIT OF AN OVERVIEW OF THAT THIS TIME.

AND THEN I THINK WE'RE PROBABLY COMING BACK IN A FEW MONTHS TO DIVE DEEPER INTO SOME MORE DETAILS.

UM, SO THAT'S KIND OF THE OVERVIEW OF WHAT WE'RE GONNA DO TODAY.

THERE'S A LITTLE BIT OF TIME AT THE END FOR SOME QUESTIONS AND DISCUSSIONS, BUT IF YOU HAVE A BURNING QUESTION, FEEL FREE TO ASK US WHILE WE'RE PRESENTING AS APPROPRIATE.

SO WITH THAT, I THINK WE'LL GO TO THE NEXT SLIDE AND I WILL PASS IT TO BROOKE.

THANKS.

UM, YEAH, SO WE KIND OF JUST WANTED TO GIVE A QUICK REFRESHER, UH, FOR FOLKS WHO ARE HERE DURING THOSE WATER FORWARD 18 CYCLE, AS WELL AS FOLKS WHO ARE NEW, UH, UH, SINCE THEN AND KIND OF TALK ABOUT WHAT DECENTRALIZED RECLAIM MEANS, UH, IN THIS AWESOME WATER, WATER PORT CONTEXT.

UM, AND SO BASICALLY YOU CAN REFER TO DIFFERENT TYPES OF DECENTRALIZED RECLAIM SYSTEMS THAT COLLECT SOME KIND OF, OF AFFLUENT, UH, FROM A WASTEWATER SYSTEM, UH, AND NEW DEVELOP, PRIMARILY NEW DEVELOPMENT AREAS OR, OR MORE GREENFIELD DEVELOPMENT AREAS, UM, THAT

[00:15:01]

UM, SMALLER SCALE TREATMENT PLANTS OR, OR, UH, SEWER MINING PLANTS OR, UM, POTENTIALLY OTHER TECHNOLOGIES THAT WILL TREAT WASTE WATER TO A NON-DRINKING WATER QUALITY AND REDISTRIBUTE, UH, THAT WASTE WATER THROUGH A SMALLER SCALE RECLAIMED SYSTEM.

SO I'M SURE A LOT OF YOU'RE ALREADY FAMILIAR WITH THE PURPLE PIPE CENTRALIZED RECLAIM SYSTEM THROUGHOUT MOST OR MUCH OF THE CENTRAL CORE OF THE CITY.

UM, THIS IS THE SAME CONCEPT JUST ON A MUCH SMALLER SCALE AND USUALLY ON MORE OF THE OUTLYING PARTS OF THE CITIES THAT HAVE, THAT ARE SERVED BY REMOTE TREATMENT FACILITIES.

UM, MOSTLY FOCUSED IN LIKE THE NORTHEAST, NORTHWEST AND, UH, SOUTHEAST CURRENTLY.

UH, AND THESE ARE MEANT TO, THESE SYSTEMS ARE KIND OF MEANT TO BE USED AT A COMMUNITY SCALE AS OPPOSED TO THE ONSITE WATER REUSE, UH, SYSTEM, UM, TEAM THAT KIND OF MANAGES THE PROGRAM FOR LOT SCALE SYSTEMS THAT DO MORE GRAY WATER, RAIN WATER, ET CETERA.

UH, AND THEN ON THE BOTTOM WE KIND OF HAVE A GRAPHIC OF THREE POTENTIAL DIFFERENT TYPES OF SYSTEMS. WE'RE, OH, SORRY, COULD YOU GO BACK FOR A SECOND? THANKS.

UM, WE'RE GONNA BE FOCUSING MOSTLY TODAY ON THE IMAGE, ON THE FAR RIGHT, THE DISTRIBUTED WASTEWATER REUSE COMMUNITY SCALE SYSTEMS. BUT, UM, WE ARE ALSO, UH, WE ALSO HAVE, UH, COMMUNITY SCALE STORM WATER HARVESTING AND COMMUNITY SCALES, SEWER MINING SYSTEMS WITHIN THE PURVIEW OF THIS GROUP.

UH, NEXT SLIDE PLEASE.

UH, SO WE JUST KIND OF WANTED TO REMIND, I GUESS, IN TERMS OF WATER FORWARD TARGETS, HOW DECENTRALIZED RECLAIM SYSTEMS AND, UH, UH, FIT IN IN TERMS OF OVERALL YIELD PROJECTIONS THAT WERE PRODUCED FOR THE 2018 PLAN.

AND JUST KIND OF TOUCH ON SOME HIGH, UM, HIGH LEVEL ASSUMPTIONS JUST JUST TO GIVE A SENSE OF, UM, WHAT KIND OF IMPLEMENTATION WE'RE EXPECTING TO SEE, UH, OVER THE NEXT SEVERAL DECADES.

SO, UM, THE WATER FORWARD TARGETS IN 2018 WERE ESTIMATED BASED ON AN ASSUMED KIND OF UPTAKE OR SATURATION RATE OF TECHNOLOGIES FOR ALL OF THE DIFFERENT ONSITE WATER REUSE TECHNOLOGIES THAT YOU SEE LISTED.

ANY, EVERYTHING FROM RAINWATER HARVESTING DOWN TO, UH, STORM WATER HARVESTING AND THOSE UPTAKE RA UH, RATES WERE ASSUMED TO RANGE BETWEEN 10 TO 30% DEPENDING ON THE TECHNOLOGY.

AND THOSE ARE KIND OF JUST MORE FOR THE LOT SCALE SYSTEMS, UH, FOR THE DECENTRALIZED, UH, RECLAIMED SYSTEMS, BECAUSE THEY'RE MORE COMMUNITY SCALE, WE EXPECTED THEM TO HAVE A LOT HIGHER UPTAKE, UH, IN TERMS OF THE NUMBER OF CUSTOMERS THAT WOULD BE ADOPTING THEM AND USING THE RECLAIMED WATER WITHIN THEIR, UH, UM, WITHIN THEIR BUILDINGS.

AND SO THOSE ASSUMPTIONS WERE CLOSER TO LIKE THE 70% UPTAKE RANGE FOR PARTICULAR SERVICE AREA THAT WOULD BE AVAILABLE TO, UM, CONNECT TO A DECENTRALIZED RECLAIM SYSTEM.

UM, SO THE TABLE SHOWS THE DIFFERENT, UH, SOURCE WATERS FOR, UH, STRATEGIES FOR WATER FOUR 18, AND THEN IN THE FOURTH COLUMN FROM THE LEFT THAT SHOWS THE 2040 YIELD TARGETS IN MGD OR MILLION GALLONS PER DAY.

AND THOSE NUMBERS ARE JUST THERE TO KIND OF HELP CALIBRATE THE SIZE OF EACH OF THESE, UM, STRATEGIES IN TERMS OF HOW MUCH, UM, ADDITIONAL RECLAIMED WATER THEY'RE EXPECTED TO PRODUCE.

SO ONSITE SYSTEMS ALL RANGE BETWEEN 0.4 TO TWO AT MILLION GALLONS PER DAY EXPECTED YIELD BY 2040, AND THAT'S WITH DISTRIBUTED ADOPTION THROUGHOUT OUR SERVICE AREA.

UH, AND THEN THE, UM, SEWER MINING AND DISTRIBUTED WASTEWATER REUSE, WHICH ARE MORE OF THE DECENTRALIZED RECLAIMED SYSTEMS ARE EXPECTED TO PRODUCE SOMEWHERE BETWEEN, UH, DEPENDING ON THE SCENARIO 0.9 NGD SEWER MINING AND, UH, 2.8 AND, UH, MGD FOR DISTRIBUTED WASTEWATER REUSE.

AND THEN TO PUT THAT IN FURTHER CONTEXT, THE SUM TOTAL OF ALL OF THE OTHER DEMAND MANAGEMENT STRATEGIES, UM, UM, THINGS LIKE AMI UH, LEAK, REDUCTION OF LEAK DETECTION FROM AMI, UM, WATER LOSS CONTROL, IRRIGATION EFFICIENCY INCENTIVES, ET CETERA.

UM, WERE ESTIMATED TO PRODUCE A TOTAL SAVINGS OF ABOUT 20 MGD BY 2040.

AND THEN FOR EVEN MORE PERSPECTIVE, THE AQUIFER STORAGE AND RECOVERY PROJECT IS ESTIMATED TO HAVE A YIELD OF ABOUT 55 MGD OR 54 MGD BY 2040.

AND THAT WOULD BE AS A DROUGHT STRATEGY.

SO NOT CONTINUALLY USED BUT ANTICIPATED TO BE USED, UM, DURING DROUGHT PERIODS, UP TO, UM, A MAXIMUM VOLUME OF, UM, THIS 53.5 MGD, OR SOME OF YOU MAY BE MORE FAMILIAR WITH THE 60,000 ACRE FEET PER YEAR.

YEAH, SHOULD HAVE HAD ANOTHER COLUMN ON THERE TO, FOR CONVERT BETWEEN THE TWO.

UH, BUT YEAH, NO, THAT'S A GREAT CLARIFICATION.

THANKS BUDDY.

ASA FOR, JUST FOR CONTEXT ON THAT, OUR AVERAGE DAY DEMAND IS ROUGHLY 1 25 ISH MGD.

SO TO CALIBRATE YOU TO HOW MUCH WATER WE'RE USING RIGHT NOW, I THINK YOU GUYS TALK AN ACRE FEET MUCH MORE FREQUENTLY THAN WE DO.

SO WE'LL MAKE SURE TO SEND OUT A UPDATED VERSION OF THE SLIDES, .

UM, AND I WILL TURN IT OVER TO MICHELLE TO TALK A LITTLE BIT MORE ABOUT DECENTRALIZED RECLAIMED AS A WHOLE QUICK QUESTION REALLY

[00:20:01]

QUICK.

SURE.

UM, THE FOURTH, SORRY, THE COLUMN TWO, THREE AND FOUR IS SINGLE FAMILY, MULTI-FAMILY AND COMMUNITY.

WHAT'S THE CM? OH, SORRY ABOUT THAT.

UM, YEAH, THAT'S, UH, COMMERCIAL.

SO THOSE ARE JUST KIND OF COMMERCIAL.

WHICH SECTORS THAT THESE STRATEGIES WOULD, WOULD APPLY TO.

ALL RIGHT, THANK YOU.

YEP.

OH, CAN I ASK ONE MORE QUESTION? GO AHEAD.

SORRY.

DO YOU, IS IT, MAYBE IT WAS ELSEWHERE IN THE PRESENTATION, I'M SORRY, BUT IS IT AVAILABLE BROKEN OUT BY THOSE CATEGORIES INSTEAD OF JUST THE TOTAL? UM, YEAH.

UH, YEAH, WE CAN PROVIDE A SUMMARY OF THAT INFORMATION, UM, UH, FOLLOWING THIS MEETING FOR SURE.

THANKS, BROOKE.

UH, NEXT SLIDE, SLIDE PLEASE.

SO THE NEXT THREE SLIDES ARE A SLIDE PROG PROGRESSION THAT JUST REITERATES WHAT BROOKE HAS TALKED ABOUT, UM, BUT IT PUTS DECENTRALIZED RECLAIM INTO CONTEXT WITH HOW IT FITS BETWEEN DECENTRALIZED VERSUS CENTRALIZED AND PRIVATE VERSUS PUBLIC.

SO WE HAVE ONSITE WATER REUSE, WHICH WE PREVIOUSLY MENTIONED THAT'S THAT LOT SCALE, PARCEL SCALE, UM, PRIVATELY OWNED.

UM, AND THAT FITS IN THE PRIVATE DECENTRALIZED QUADRANT.

UH, THAT HAVE BEEN DESIGNATED BY THE CITY.

AND THEN WE HAVE OUR CENTRALIZED RECLAIMED SYSTEM, UM, AND THAT FITS IN THE CENTRALIZED PUBLIC QUADRANT, AND THAT'S A CITY OWNED, UM, AND OPERATED NEXT SLIDE.

AND THEN WHERE WE ARE IS HERE IN THE DECENTRALIZED PUBLIC QUADRANT THAT BROOKE HAD MENTIONED, THE COMMUNITY SCALE OR DISTRICT NEIGHBORHOOD SCALE, UM, AND ALSO CITY OWNED AND OPERATED.

AND THEN NEXT SLIDE PLEASE.

AND THEN WE ALSO HAVE THIS OTHER QUADRANT THAT WE'RE NOT QUITE FOCUSING ON, UM, BUT IT'D BE THE OPPOSITE END OF PRIVATE AND CENTRALIZED LIKELY FOR OUR WHOLESALE CUSTOMERS.

NEXT SLIDE PLEASE.

AND THEN I'LL PASS IT BACK TO BROOKE.

THANKS.

UM, SO YEAH, SO, UH, THE MAP ON THE LEFT SHOW WAS AN EXHIBIT THAT WAS PRODUCED BY, UH, GD, WHO WAS THE SUB-CONSULTANT FOR THE INITIAL DECENTRALIZED ANALYSIS IN WATER FORWARD 2018.

UM, AND IF YOU KIND OF LOOK ON THE RIGHT HAND SIDE OF THE ME OR, YEAH, ON THE RIGHT HAND SIDE OF THE MAP, KIND OF IN THE EASTERN CRESCENT AREA, YOU CAN SEE SEVERAL DIFFERENTLY COLORED POLYGONS THAT SHOW, UM, POTENTIAL SERVICE AREAS FOR, UH, UH, OUR DECENTRALIZED OR DISTRIBUTED WASTEWATER REUSE SYSTEMS UNDER THE DECENTRALIZED RECLAIMED BANNER.

UH, AND MOST OF THOSE ARE REPRESENT, UM, EITHER, UH, EXISTING, UH, AREAS THAT HAVE REMOTE WASTEWATER TREATMENT FACILITIES ALREADY IN OPERATION AND RECLAIMED FACILITIES WOULD BE KIND OF OUTFITTED, UH, ON THOSE SITES TO BE ABLE TO MAKE USE OF THE TREATED WASTEWATER EFFLUENT THAT IS CURRENTLY BEING PRODUCED, UM, AND USE THAT FOR NON, UH, POTABLE DEMANDS.

UM, AND THEN THERE ARE ALSO A FEW, UH, POLYGONS KIND OF IN THE NORTHERN AND SOUTHERN REGIONS THAT REPRESENT, UM, POTENTIAL AREAS THAT DON'T CURRENTLY HAVE ANY INFRASTRUCTURE, UM, OR ANY, UH, WASTEWATER TREATMENT INFRASTRUCTURE, BUT COULD, UH, SERVE AS A, UM, UH, DECENTRALIZED RECLAIMED SERVICE AREA JUST BASED ON LONG RANGE PLANNING FOR THE CENTRALIZED AND, AND, UH, DECENTRALIZED, UH, INFRASTRUCTURE WORKS.

UH, AND THEN THEY'RE, I DON'T BELIEVE THEY'RE HIGHLIGHTED ON THE MAP ON THE LEFT.

UH, THEY MIGHT BE CALLED OUT, IT'S HARD TO TELL FROM HERE.

BUT WE ALSO HAVE THREE EXISTING PLANTS, UM, THAT CURRENTLY PRODUCE RECLAIMED WATER FOR, UM, UH, NEARBY GOLF COURSES, UH, THAT, UH, THAT ARE ADJACENT TO THOSE PLANT SIZE.

UH, THE MAP ON THE RIGHT, UH, SHOWS KIND OF AN UPDATED VERSION OF THIS MAP WITH UPDATED SERVICE AREAS.

UM, A COUPLE OF, OR ONE SERVICE AR TWO SERVICE AREAS WERE MERGED, UM, BASED ON KIND OF UPDATES IN THE LONG RANGE PLAN FOR THE WASTEWATER INFRASTRUCTURE IN THAT AREA.

AND THEN A FEW OTHER POTENTIAL AREAS WERE HIGHLIGHTED, UM, UH, ONE BEING ALONG THE EL THE ELM CREEK BASIN AREA, KIND OF JUST SOUTH OF DECKER LAKE, UH, AS WELL AS A POTENTIAL, UH, SERVICE AREA IDENTIFIED IN THE BEAR CREEK BASIN IN, IN SOUTHWEST AUSTIN.

UH, WE ALSO ADDED THE, UM, PURPLE KIND OF HATCHING IN THE CENTER OF THE CITY REPRESENTS THE LONG RANGE MASTER PLAN FOR THE CENTRALIZED RECLAIM SYSTEM.

SO THAT WOULD KIND OF BE AREAS THAT WOULDN'T BE SERVED BY THESE SMALLER FACILITIES, BUT WOULD BE SERVED BY THE LARGER PURPLE PIPE NETWORK.

UM, AS WELL AS A, UH, SOME, UH, AREAS WHERE, UH, UM, RECLAIM, UH, RECLAIM OR WASTEWATER TREATMENT MIGHT BE COMPLICATED BASED ON ENVIRONMENTAL FACTORS, KIND OF BASED ON, UH, THAT ARE SHOWN IN THE FAR WEST AREA ALONG WITH THE EDWARDS AQUIFER RECHARGE ZONE.

UM, AND YOU CAN KIND OF SEE SOME GREEN, SOME GREEN AND BLUE SPLOTCHES REPRESENTING WATER QUALITY PROTECTION LANDS,

[00:25:01]

AND THEN FINALLY, THE GRAY, UM, THE GRAY, UH, POLYGONS OFF TO THE RIGHT REPRESENT OTHER JURISDICTIONS THAT AREN'T CURRENTLY CITY OF AUSTIN.

UM, AND SO WE, IF YOU EXCLUDED THEM FROM OUR ANALYSIS, UH, FOR THE, UH, CURRENTLY FOR THIS PURPOSE.

UH, NEXT SLIDE, PLEASE.

SO I MENTIONED THAT WE HAD THREE, UH, EXISTING WASTEWATER TREATMENT PLANTS, UM, LOCATED ON THE WESTERN PORTION OF THE CITY.

THOSE ARE THE BALCONES WASTEWATER TREATMENT PLANT, THE RIVER PLACE WASTEWATER TREATMENT PLANT, AND THE LOST CREEK WASTEWATER TREATMENT PLANT.

UM, THOSE ALL, UH, THOSE SITES ARE ALL ADJACENT TO, UH, UM, GOLF COURSES SPREAD THROUGHOUT THE CITY AND, AND THE TREATED WASTEWATER LAN FROM THOSE PLANTS PROVIDE RECLAIMED IRRIGATION WATER FOR THOSE GOLF COURSES.

UM, THAT'S NOT TO SAY THAT GOLF COURSE IRRIGATION WILL BE THE ONLY USE GOING FORWARD, BUT THAT'S JUST THE CURRENT USES OF THOSE, THOSE FACILITIES.

UM, WE ALSO HAVE THREE, UH, EXISTING FACILITIES ON THE EASTERN SIDE OF THE CITY, OR THE AUSTIN WATER SERVICE AREA THAT ARE IN, THAT CURRENTLY EXISTS, BUT DO NOT PRODUCE RECLAIMED, OR AT LEAST NO, UH, DO NOT PRODUCE RECLAIMED WATER YET.

THOSE ARE THE WILD HORSE WASTEWATER TREATMENT PLANT, THE TAYLOR LANE WASTEWATER TREATMENT PLANT, UH, WHICH ARE BOTH IN THE NORTHEAST AREA, AND THEN THE PIERCE LANE WASTEWATER TREATMENT PLANT IN THE SOUTHEAST, KIND OF NEAR THE CIRCUIT OF AMERICA'S, UH, RACE TRACK.

AND THEN WE'VE IDENTIFIED FOR OTHER, UH, FUTURE CONCEPTUAL SERVICE AREAS BASED ON WHERE WE EXPECT DEMANDS TO GROW AND POTENTIAL FOR, UM, DECENTRALIZED INFRASTRUCTURE TO BE PUT, UH, TO, UH, TO BE, UH, INSTALLED.

UH, THOSE WOULD BE IN THE LAKE AND ROTAN CREEK BASINS UP IN, IN NORTHWEST AUSTIN.

UM, THE ALMOND DECKER BASINS, AS I MENTIONED PREVIOUSLY IN, UH, JUST, UH, RIGHT AROUND DECKER LAKE, THE NORTH AND SOUTH FORK, UM, RIVER BASINS, WHICH ARE JUST TO THE WEST OF, OF PIERCE LANE, KIND OF IN SOUTH AUSTIN, NEAR PILOT KNOB AND, UH, THE BEAR IN LITTLE BEAR CREEK BASINS, UM, IN SOUTHWEST AUSTIN.

TO MAKE FULL USE OF, I SHOULD SAY, THE RECLAIMED POTENTIAL IN THE AREA.

UM, SO WE'RE GONNA TALK ABOUT, UH, TWO SPECIFIC CASES THAT WE'VE BEEN, UM, UH, DOING SOME ADDITIONAL ANALYSIS ON SINCE THE WATER FORWARD 2018, UM, EFFORT.

UM, AND KIND OF KIND OF BRING UP SOME, SOME MAJOR TAKEAWAYS AND, AND INSIGHTS THAT WE'VE, UH, UH, LEARNED AS WE'VE BEEN KIND OF REASSESSING THE FEASIBILITY OF DECENTRALIZED RECLAIMED IN THESE AREAS.

SO THE FIRST AREA I'M GONNA TALK ABOUT IS, UH, THE WILD HORSE BASIN, UM, LOCATED IN NORTHEAST AUSTIN, KIND OF EXTENDING NORTH, UH, FROM THE NORTH OF DECKER LAKE, UH, UP TO NEAR, UH, FLUER AREA TO KIND OF THE UPPER EDGE OF, UH, AUSTIN WATER SERVICE AREA.

UM, THE WILD HORSE WASTEWATER TREATMENT PLANT WAS, UM, UM, WAS, WAS CREATED IN, I THINK THE MID TWO THOUSANDS AS PART OF AN AGREEMENT WITH THE WILD HORSE PLANT UNIT DEVELOPMENT.

UM, SO THAT AS A, UH, UH, A PLANT DEVELOPMENT THAT, UH, IS CURRENTLY IN THE PROCESS OF, UH, DEVELOPING, UH, IT'S GONNA BE LIKE A LARGE SCALE, UM, COMMUNITY WITH SINGLE FAMILY HOMES, MULTIFAMILY HOMES, COMMERCIAL USES, ET CETERA, ET CETERA.

AND THE WASTEWATER TREATMENT PLANT WAS CONSTRUCTED IN ORDER TO SERVE THAT DEVELOPMENT AS WELL AS, UM, A LOT OF OTHER DEVELOPMENT IN THE NORTHEAST AREA.

AND THIS, THIS AREA HAS BEEN RAPIDLY GROWING, UH, OVER THE PAST DECADE AND A LITTLE BIT EVEN BEFORE THAT.

AND, UH, REP AND KIND OF REFLECTS, UM, AN OPPORTUNITY TO MAKE USE OF SOME OF THE, UH, IT KIND OF, IT KIND OF REPRESENTS THAT GREENFIELD DEVELOPMENT SCENARIO THAT I HAD MENTIONED PREVIOUSLY WHERE, UM, IF WE'RE ABLE TO, UH, UH, INSTALL, UH, RECLAIMED INFRASTRUCTURE AND, AND, UH, UM, INCENTIVIZE OR REQUIRE ADOPTION OF, OF RECLAIMED INFRASTRUCTURE, UM, YOU'D BE ABLE TO SEE LARGER RECLAIMED, UH, YIELDS FROM, FROM NEW CONSTRUCTION IN THE AREA.

UM, RIGHT NOW THE WASTEWATER TREATMENT PLANT IS UNDER AN EXPANSION PRO, UH, PROJECT AND EXPECTED IT'S ABOUT, HAS ABOUT 0.75 OR 750,000 GALLONS PER DAY OF CAPACITY RIGHT NOW.

AND THAT'S EXPECTED TO TRIPLE TO 2.25 MILLIONS, UH, GALLONS PER DAY.

I BELIEVE THAT PROJECT IS EXPECTED TO BE COMPLETED, UM, BY 2026 OR SO.

AND, UM, ADDITIONAL EXPANSIONS MIGHT BE LIKELY DEPENDING ON GROWTH TRENDS, UH, IN, IN THE AREA.

SO, UM, IT DOES REPRESENT A, A RELATIVELY LARGE SOURCE OF, UH, TREATED WASTEWATER EFFLUENT THAT CAN BE USED FOR RECLAIMED DEMAND.

UM, HOWEVER MUCH OF THE, UM, MUCH OF THE UNDEVELOPED AREA IN THE, IN THE, IN THE SERVICE AREA HAS BEEN, UH, UM, VERY RAPIDLY BEING ACCOUNTED FOR BY DEVELOPMENT APPLICATIONS OVER THE PAST EVEN COUPLE OF YEARS, THREE TO FIVE YEARS.

UH, AND WHAT WE'RE UH, FINDING IS THAT, UM, THE, THE PACE OF GROWTH IN THIS AREA MIGHT ACTUALLY BE OUTPACING, UM, THE, UH, NECESSARY RESTRUCTURED, PROVIDE RECLAIMED, UH,

[00:30:01]

UM, NEXT SLIDE PLEASE.

SO THAT KIND OF HIGHLIGHTED A FEW, UM, NEXT STEPS FOR OUR GROUP TO KIND OF WORK ON.

UM, RIGHT NOW THERE'S CURRENTLY, UH, SPACE ON THE SITE DESIGNATED FOR RECLAIMED FACILITIES.

UH, AND SO A FUTURE EXPANSION OF THE SITE MIGHT INCLUDE RECLAIM A CONSTRUCTION OF RECLAIMED FACILITIES GOING FORWARD, OR RECLAIMED FACILITIES MIGHT BE CONSTRUCTED IN A SEPARATE PROJECT OUTSIDE OF A TREATMENT PLAN EXPANSION.

UM, BUT, UH, A CONSTRUCTION OF THAT, OF THAT INFRASTRUCTURE IS ONLY ONE PART OF THE, THE, UM, ONE PIECE OF THE PUZZLE.

WE WOULD ALSO NEED TO LOOK TOWARDS MORE POLICY MECHANISMS TO EITHER INCENTIVIZE OR REQUIRE ADOPTION BY NEW DEVELOPMENT, UH, IN ORDER TO MAKE USE OF THAT RECLAIMED WATER, UM, WHETHER THAT WOULD BE THROUGH, UM, A COMBINATION OF THE RE A MANDATORY RECLAIMED CONNECTION ORDINANCE OR OTHER POLICY MECHANISMS AS TO BE DETERMINED.

UM, AND RIGHT NOW THERE ARE NO INCENTIVE MECHANISMS AVAILABLE EXCEPT FOR THE LARGE SCALE.

UM, UH, I THINK IT'S OVER 250,000 SQUARE FEET DEVELOPMENTS OR SO THAT'S CURRENTLY AVAILABLE MM-HMM.

SO FOR SMALLER PARCELS, AN ALTERNATE POLICY MECHANISM WOULD PROBABLY BE NEEDED.

UM, SO I'VE BEEN FOCUSING MY EFFORTS ON THE PIERCE LAND WASTEWATER TREATMENT PLANT, AND I WANTED TO GIVE A BRIEF OVERVIEW OF THIS PLANNING AREA.

SO WE'RE IN THE SOUTHEAST OF AUSTIN IN THE DRY SOUTH BASIN.

UM, AND YOU CAN SEE MAYBE ON THE SCREEN THERE RIGHT BELOW OUR VIDEO, SORRY, IT'S HARD TO SHOW BECAUSE IT'S BLOCKING IT, BUT THERE'S THE WASTE, THE PIERCE LANE WASTEWATER TREATMENT PLANT, THANK YOU, UM, THERE BY THE RED BOUNDARY.

UM, AND SO THIS TREATMENT PLANT WAS INITIATED AS PART OF THE SUN CHASE DEVELOPMENT BY THE SOUTHEAST TRAVIS COUNTY MUD.

UM, AND THEY CONSTRUCTED THE, UH, INITIAL CAPACITY OF 0.3 MGD.

UM, I ACTUALLY THINK THE CAPACITYS 0.4, BUT IT'S PERMITTED FOR 0.3.

UM, AND, UH, IT IS DESIGNED FOR AN ULTIMATE CAPACITY OF 2.25 MGD, AND THIS IS CURRENTLY TO SERVE THAT DEVELOPMENT.

HOWEVER, THERE IS ROOM AT THE TREATMENT PLANT FOR NON MUD FLOWS AS WELL, SO FOR, UM, OTHER, UH, AREAS TO BE SERVED BY THAT PLANT AROUND, UM, THAT RED BOUNDARY.

BUT WE ARE LOOKING AT THE ENTIRE DRY SOUTH BASIN TOO, FOR POTENTIAL, UM, CUSTOMERS.

UM, AND WE'VE BEEN SEEING A LOT OF DEVELOPMENT INTEREST IN THIS AREA AS WELL HIGHLIGHTED IN THE, UM, SCREENSHOT THERE WITH, UH, THE PINK POLYGONS.

THOSE ARE WASTEWATER SCR THAT WE'VE SEEN COMING RECENTLY.

UM, AND SO WE THINK THERE IS A, A GOOD POTENTIAL FOR DEVELOPMENT AND REDEVELOPMENT WITHIN THIS BASIN.

NEXT SLIDE PLEASE.

AND THEN, UM, SORRY, I HOPE THAT WAS CLEAR, BUT WE'RE IN THE SOUTHEAST, LIKE I SAID, BY HIGHWAY 71 IN STATE HIGHWAY ONE 30, UM, NEAR THE CIRCUIT OF AMERICA'S RACE TRACK IN CASE.

YEAH, WE WEREN'T SURE .

UM, BUT SOME OF THE OPPORTUNITIES AND CHALLENGES THAT WE'VE SEEN IN THIS AREA, UM, IS THAT THE SOUTHEAST TRAVIS COUNTY MUD PER THEIR CONSENT AGREEMENT ARE, UM, REQUIRED TO CONSTRUCT A RECLAIMED WATER FACILITY ON SITE AT THE PLANT.

UM, THEY ARE TO DESIGN UP TO 2.25 M G D AND CONSTRUCT UP TO 1.25 NGD OF THE RECLAIMED FACILITY.

SO THERE IS OPPORTUNITY TO INCORPORATE RECLAIM SOONER IN THIS AREA.

UM, AND, UH, HOWEVER WE WOULD NEED POLICIES TO REQUIRE THOSE POTENTIAL CUSTOMERS TO USE THESE FACILITIES.

CAN I ASK A QUICK QUESTION? QUESTION? YES, OF COURSE.

SPEAK A LITTLE BIT FOR THE TEAM HERE, BUT I THINK THE POLICIES THAT WE ARE DISCUSSING AT THIS POINT ARE AUSTIN WATER POLICIES AND, UM, MUNICIPAL CODES AND REQUIREMENTS, NOT NECESSARILY STATE LAW OR POLICY.

THIS IS SUPER INTERESTING.

UM, SO WHEN Y'ALL ARE SAYING THAT THAT POLICIES ARE NEEDED TO REQUIRE POTENTIAL CUSTOMERS TO USE THESE NEW DECENTRALIZED RECLAIMED FACILITIES THAT HOPEFULLY COULD BE BROUGHT ABOUT WHEN THESE ENTITIES ARE EXPANDING THEIR WASTEWATER TREATMENT PLANTS, I'M JUST, I'M THINKING THROUGH LIKE, WOULD THAT NEED TO BE LIKE A STATE LAW CHANGE THEN TO REQUIRE NEW DEVELOPMENTS TO, UM, BAD RECLAIMED WATER INFRASTRUCTURE WHEN THEY ARE EXPANDING THEIR, UM, PLANTS? OR IS THAT SOMETHING THAT WOULD BE A TCQ RULE? I DON'T KNOW.

MAYBE SARAH KNOWS THE ANSWER TO THAT , BUT I'M JUST TRYING TO THINK LIKE WHAT KIND OF POLICIES, UM, YOU ARE REFERENCING.

I THINK THAT WE'RE, UM, AND I'M GONNA

[00:35:01]

UM, DO Y'ALL WANNA EXPAND ON THAT? SO YOU'RE SAYING LIKE ONCE THE ONCE THIS INFRASTRUCTURE IS BUILT, THEN YOU'RE LOOKING AT LOCAL POLICY THAT WOULD ACTUALLY ENCOURAGE, UM, CUSTOMERS TO USE THIS.

NOW.

THERE ARE SOME DIFFERENCES IN TERMS OF JURISDICTION.

SO RIGHT NOW WE HAVE OUR, OUR, UH, ORDINANCE THAT APPLIES TO THE CENTRALIZED RECLAIM WATER SYSTEM, UM, THAT IS A PART OF THE LAND DEVELOPMENT CODE THAT HAS A SPECIFIC AREA, UM, WITHIN OUR FULL PURPOSE JURISDICTION THAT IT APPLIES TO.

AND THERE ARE, UM, ADD THERE ARE ADDITIONAL CONSIDERATIONS FOR, UH, APPLICATION OF THAT ORDINANCE LANGUAGE TO AREAS THAT MAY BE OUTSIDE OF OUR FULL PURPOSE AND OR LIMITED PURPOSE JURISDICTION THAT ARE WITHIN THE EJ OF THE CITY.

SO THOSE WOULD BE SOME, UH, UH, ISSUES THAT WE WOULD HAVE TO WORK THROUGH IN ORDER TO HAVE, UM, UH, IMPLEMENT TO BE ABLE TO, UH, IMPLEMENT THOSE CONNECTION REQUIREMENTS ON CUSTOMERS THAT MAY BE OUTSIDE OF OUR FULL PURPOSE AND LIMITED PURPOSE JURISDICTION.

DID OTHER FOLK YES, GO AHEAD.

JUST A, JUST A QUICK QUESTION.

DOES THOSE ARE CURRENT PLAN AND VISION, PUTTING THESE REQUIREMENTS IN AND INCENTIVES IN FOR FOLKS TO USE RECLAIMED WATER? SO THIS IS PART OF WHAT WE'RE WORKING THROUGH RIGHT NOW IS OUR CURRENT PLAN ENVISIONS GETTING A RECLAIMED YIELD OUT OF THESE STRATEGIES.

IN ORDER TO ACHIEVE THE RECLAIM YIELD, WE NEED TO HAVE SOME MECHANISM OF EITHER INCENTIVIZING OR REQUIRING FOLKS TO CONNECT TO THOSE SYSTEMS, OTHERWISE WE WON'T BE ABLE TO ACHIEVE THE YIELD.

SO WHAT WE'RE WORKING THROUGH INTERNALLY AND WHAT THIS TEAM HAS BEEN TAKING ON IS, UH, KIND OF IDENTIFYING WHAT ARE THE DIFFERENT OPPORTUNITIES, UH, CHALLENGES AND MECHANISMS THAT WE CAN USE, UM, THROUGH DEVELOPMENT AGREEMENTS, THROUGH CODE, THROUGH, UM, SYSTEM AUSTIN WATER POLICIES, THROUGH INCENTIVES OR OTHER, UM, OTHER MEANS TO BE ABLE TO, UM, CONNECT FOLKS.

SO THE CURRENT PLAN DOES NOT HAVE THOSE INCENTIVES AND REQUIREMENTS, NOT SPECIFICALLY ENVISIONED, BUT WITHOUT THEM, WE DON'T GET THE YIELD , I JUST WANNA MAKE SURE WHAT'S, WHAT'S, UH, SURE.

THEY'RE, THEY'RE CRITICAL IMPLEMENTATION COMPONENTS OF BEING ABLE TO ACHIEVE SUCCESS WITH THE STRATEGY.

I MEAN, I THINK, I THINK THE PLAN, YOU KNOW, OUR, OUR WATER 4 20 18 PLAN HAS GOALS FOR EACH OF THESE STRATEGIES.

AND IT, AND IT, IT DOESN'T LAY OUT SPECIFICALLY A, B AND C OF HOW WE'RE GONNA GET THERE.

AND LIKE, LIKE THE FEW THINGS THAT WE'VE HAD GO THROUGH SO FAR WITH IMPLEMENTATION, THERE HAVE BEEN REQUIREMENTS THAT HAVE BEEN PUT INTO PLACE, INCENTIVES, ORDINANCES PASSED, WHATEVER.

SO LIKE THE WATER FORWARD PLAN ISN'T AT THE DETAIL MM-HMM.

WHERE, WHERE ALL OF THAT IS LAID OUT MM-HMM.

AND AS WE MOVE THROUGH IMPLEMENTATION, THOSE THINGS, THERE'S SEVERAL PATHWAYS FLOWING FROM WATER FORWARD 18 THAT ARE BEING WORKED OUT RIGHT NOW.

THAT'S ABSOLUTELY RIGHT ON.

WATER FORWARD IS A HUNDRED YEAR STRATEGIC PLAN.

AFTER THE ADOPTION OF THE PLAN, WE STARTED THAT IMPLEMENTATION, TACTICAL PLANNING THAT IS MUCH MORE DETAILED.

HOW DO WE ACTUALLY ACHIEVE THE YIELD TARGETS THAT WE LAID OUT IN THE PLAN? AND SO, UM, FORGIVE MY IGNORANCE ON THE, YOU KNOW, THE MUD AND THE ALL, ALL THIS AND HOW THAT ALL WORKS AND, AND WHERE EXACTLY THE EVERYTHING THAT WE'RE LOOKING AT IS IN THE CITY OF AUSTIN, BECAUSE THAT'S WHERE THINGS AND ORDINANCES AND REGULATIONS THAT WE PASS WOULD BE IN EFFECT.

OR WE CAN DO THAT FOR A WHOLESALE CUSTOMERS DO IF, IF THEY AGREED TO IT IN THEIR CONTRACTS.

SO KEVIN CRITTENDON, AUSTIN WATER, WE ARE INTO SOMEWHERE CRAZY.

NO, ACTUALLY, ACTUALLY YOU'RE GETTING VERY MUCH INTO THE DETAILS OF KIND OF WHAT THAT LAST BULLET REALLY IS ABOUT.

AND DISTINGUISH THAT FROM WHAT'S ALLOWED IN THE ETJ OR THE EXTRA TERRITORIAL JURISDICTION.

, RIGHT.

AGAIN, TO RE TO TO STEP BACK A BIT, WATER FORWARD IS STRATEGIC PLAN AND HAS A NUMBER OF STRATEGIES.

THE DETAILS OF HOW ANY OF THOSE STRATEGIES ARE APPLIED CAN CHANGE DEPENDING ON WHERE IN THE WORLD A DEVELOPMENT OR USER IS.

AND THAT'S BASED ON, UM, CURRENT CITY CODE AND HOW IT'S APPLIED, NOT INDICATED.

THERE'S A NUMBER OF VERY SUBTLE DISTINCTIONS ABOUT WHAT IS PERMISSIBLE WITHIN THE FULL PURPOSE AREA, WHICH IS CLASSICALLY SORT OF THE CITY LIMITS

[00:40:01]

THOSE ARE DIFFERENT PLANNING JURISDICTIONS.

AND SO THESE ARE EXACTLY THE KINDS OF THINGS THAT WE'LL HAVE TO DO WHEN WE START TO THINK ABOUT DEVELOPMENT IN THESE AREAS.

, THESE PARTICULAR PLANTS, UM, WHILE MOST OF THEM WERE CONSTRUCTED THROUGH A CONSENT AGREEMENT WITH THE CITY OF AUSTIN ABOUT SORT OF THE, THE, HOW THOSE PLANTS WOULD BE DEVELOPED, UM, THOSE PLANTS ARE NOW OWNED BY THE CITY OF AUSTIN.

I'M LOOKING AT ALL, KEEP ME HONEST HERE.

JUST IT'S A TIMING ISSUE MOSTLY.

UM, BUT THEY ARE STILL IN THE EJ AND NOT IN THE, UM, EXCUSE ME, THE, I DREW A COMPLETE BLANK.

NOT IN THE FULL PURPOSE, IN THE FULL PURPOSE JURISDICTION.

SO, GREAT.

UM, TWO QUESTIONS.

ONE IS, WHAT ARE THE KINDS, AND THIS MAY NOT HAVE BEEN FIGURED OUT YET, BUT FOR SAY EACH OF THESE AREAS, WHERE WOULD WE SEE THE USE OF, OF THE RECLAIMED WATER USED IN THESE AREAS? IT'S, UM, IT LOOKS LIKE IT'S GONNA BE, I DON'T KNOW IF IT'S GONNA BE LARGELY RESIDENTIAL DEVELOPMENT OR WHAT, SO, SO FOR EXAMPLE, WHERE WOULD, HOW WOULD THAT WATER BE USED AND WHERE, UM, YEAH.

SO FOR THE WATER FORWARD 2018 ANALYSIS, IT INCLUDED SINGLE FAMILY, MULTI-FAMILY AND COMMERCIAL USES.

UM, RIGHT NOW AND SINCE, SINCE THE ADOPT, SINCE THE ADOPTION OF WATER FORWARD 2018, UM, MICHELLE AND I REVIEWED A LOT OF THE DEVELOPMENT APPLICATIONS IN THE AREA.

THEY TEND TO RANGE FROM, UH, LARGE SINGLE FAMILY SUBDIVISIONS THAT I THINK IS THE MAJORITY OF OF THEM.

, BUT THERE ARE SOME KIND OF SMALLER MIXED USE, UH, DEVELOPMENTS AS WELL.

ESPECIALLY DEPENDING ON, AS YOU GET CLOSER TO THE CITY, UM, YOU START TO SEE MORE MULTIFAMILY AND SOME COMMERCIAL.

THE WILD PUT, AS I MENTIONED, IS LIKE A MASTER PLANNED COMMUNITY WITH SECTIONS OF SINGLE FAMILY, BUT ALSO SECTIONS OF COER LIKE COMMERCIAL AND MULTI-FAMILY MIXED USE TO BE ITS OWN KIND OF, ALMOST LIKE A MUELLER TYPE, UH, UH, SCENARIO.

SO, OKAY.

IT'S REALLY A MIX, BUT, UM, IT SEEMS TO BE PREDOM LIKE LEANING, I WOULD SAY A PLURALITY OF SINGLE FAMILY HOMES.

AND I'M GLAD YOU MENTIONED MUELLER, CUZ WHAT I ENVISION WHEN YOU TALK ABOUT LIKE SINGLE FAMILY LIKE DEVELOPMENT SUBDIVISION TYPE THINGS, WHAT I IMAGINE IT WOULD BE, YOU KNOW, LIKE CUZ MUELLER HAS PURPLE PIPE THROUGHOUT IT, BUT THAT'S A CENTRALIZED RECLAIM CUZ IT'S IN THE CITY CORE WHERE IT'S THE ONLY DIFFERENCE IS REALLY, IS THAT THE WASTE WATER TREATMENT PLAN IS NOT PART OF WHAT'S ON THE CITY'S, YOU KNOW, MAIN SYSTEM.

UM, AND I GUESS MY OTHER QUESTION IS, THIS JUST LEADS INTO IT AND I'M, AND I'M KIND OF SEEING THE BENEFITS, UM, I GUESS I'VE SEEN 'EM ALL, I'VE SEEN 'EM ALL ALONG, BUT, BUT BACK WHEN WE DID THE 20, THE 2018 WATER FORWARD PLAN AND, AND THE WORK THAT JOE AND HIS TEAM DID ON THE DISAGGREGATED DEMAND MODEL AND THEN BEING ABLE TO GO IN AND LOOK CUZ WE HAVE PROJECTIONS AND WHERE WE THINK THAT'S GONNA BE REALITY SOMETIMES DOESN'T WORK OUT THE WAY WE THINK IT IS, YOU KNOW, OR THE FUTURE.

SO THIS IS JUST GOING IN AND TAKING A LOOK AND SAYING LIKE, OKAY, WE SAID WE'RE GONNA SAVE A HUNDRED UNITS THROUGH THIS THING AND NOW WE'RE ACTUALLY SEEING WHERE WE THINK, WHERE WE THINK IT'LL LAND BASED ON THE CURRENT CONDITIONS.

THAT'S CORRECT.

AND I THINK THAT'S PART OF THE DEMAND FORECAST UPDATE THIS TIME AROUND.

IT'LL, PART OF THAT WILL INCLUDE, OH, SORRY.

PART OF THAT WILL INCLUDE, UH, LOOKING AT COMPARING TO THE PREVIOUS DEMAND FORECASTS AND THE PREVIOUS GROWTH ASSUMPTIONS, ESPECIALLY FOR THESE OUTLYING AREAS, AND THEN REASSESSING THOSE POTENTIAL YIELDS FOR, UM, THE DEMAND MANAGEMENT AND, UH, REUSE RELATED STRATEGIES.

RELATE TO AFFORDABILITY QUESTIONS AND LONG TERM WATER SUPPLY STRATEGIES.

SUPER.

DID YOU WANNA SAY SOMETHING, JOE? SEE YOUR FINGER ON THE TRIGGER THERE? SURE.

WELL, BROOKE IS DOING GREAT.

UM, I WAS GONNA ASK MICHELLE TO IN A SECOND TALK ABOUT THAT PIERCE LANE AGREEMENT.

WHAT USERS ARE SIGNED UP OR ARE IN THE CONTRACT.

WE HAVE VISUALIZED THAT, BUT YOU'RE KIND OF CLOSING IN ON SOME OF THE MAIN QUESTIONS, THE WHOLE TASK FORCES HERE OF LIKE, WE'RE GONNA NEED TO BUILD INFRASTRUCTURE PUMP STATIONS, RESERVOIRS, PIPE NETWORKS THAT TAKE THE TREATED WASTEWATER EFFLUENT, BRING IT TO CUSTOMERS.

SO WHAT CUSTOMERS ARE WE GOING TO, IF YOU CAN IMAGINE THE NETWORK TO GO TO A SINGLE FAMILY NEIGHBORHOOD THAT'S DIFFERENT THAN GOING TO A GOLF COURSE IN TERMS OF COST PER ACRE FOOT OR THOSE KINDS OF THINGS.

AND SO THOSE ARE THINGS WE NEED TO WORK OUT.

AND THEN WE NEED TO BE THINKING ABOUT FUNDING THAT INFRASTRUCTURE, THOSE PUMP STATIONS, THOSE RESERVOIRS, TANK WATER TANKS, PIPES GOING IN THE GROUND.

ARE THOSE GONNA BE ON DEVELOPERS OR THOSE OTHER INVESTMENTS THAT THE CITY IS MAKING? AND THOSE ARE SOME OF THE POLICIES THAT WE'RE GONNA NEED TO WORK THROUGH IN TERMS OF THOSE, THERE'S EXPENSES THERE THAT

[00:45:01]

SO I THINK THE TASK FORCE CAN REALLY HELP US WITH MM-HMM.

GUIDING THAT THOSE DECISIONS.

AND THEN THE SOONER WE START THINKING ABOUT THIS, AND THE SOONER WE IDENTIFY OPPORTUNITIES BEFORE PLANS ARE MADE AND PLACES ALREADY BEING BUILT OUT, THE BETTER CHANCE OF SUCCESS WE HAVE FOR ACHIEVING OUR GOALS MM-HMM.

YEP.

AS A COMMUNITY.

RIGHT.

SO WHERE DO WE ANTICIPATE USING WATER IN THE SOUTHEAST TRAVIS COUNTY? YEAH, SO IN THEIR CONSENT AGREEMENT, THEY HAVE OUTLINED THAT THEY WANNA MEET THE RECLAIMED WATER NEEDS FOR PUBLIC OPEN SPACES, PARKS, AND PRIVATE PARKS AND RECREATION FACILITIES.

SO WE'RE GONNA BE WORKING ON SETTING UP MEETINGS TO FIGURE OUT THE NEXT PHASES OF THEIR DEVELOPMENT AND WHERE ARE THOSE PUBLIC SPACES AND PARKS AND HOW ARE WE GONNA GO FROM A WASTEWATER TREATMENT PLANT ONLY TO A RECLAIMED FACILITY THERE IN THE UPCOMING YEARS.

AND EACH OF THESE AREAS, SO WE LOOKED AT TWO AREAS THAT BROOKE AND MICHELLE GAVE US AN OVERVIEW OF OR OVERVIEWS OF EACH OF THESE AREAS ARE DIFFERENT AND THEY'LL HAVE DIFFERENT OPPORTUNITIES, THEY'LL HAVE DIFFERENT CHALLENGES AND THEY WILL HAVE DIFFERENT TIMING OF DEVELOPMENT.

SO THAT'S SOMETHING WE HAVE TO KIND OF THINK THROUGH AS WELL.

IT'S NOT A ONE SIZE FITS ALL MM-HMM.

SITUATION.

UM, WE CAN'T JUST USE THE SAME APPROACHES.

WE HAVE TO, UM, CUSTOMIZE THE APPROACH TO THE PACE OF DEVELOPMENT, TO THE TYPE OF DEVELOPMENT TO THE EXISTING INFRASTRUCTURE.

AND THEN, LIKE JOE SAID, KIND OF WORK THROUGH THAT COST BENEFIT JUST TO THROW THAT OUT THERE.

YEAH, AND THE THING, UM, THAT COMES TO MIND HERE TOO IS THAT, UM, THERE'S, THERE'S, THERE'S A LOT MORE, I THINK THIS IS A REALLY GREAT INTRO, INTRODUCTION TO THIS AND KIND OF HOW DETAILED THIS IS, BUT I'M, YOU KNOW, I'M ALSO HEARING THAT THERE'S, YOU KNOW, A GOOD AMOUNT OF, OF HANDHOLDING AND WORKING WITH, UM, AND DOING SOME PLANNING.

I'M, I'M SURE THAT HAPPENS WITH ALL DEVELOPMENTS, BUT IT'S, IT'S ADDING IT A KIND OF OTHER LAYER OF IT AS WELL.

SO, UM, KUDOS TO THE FOLKS THAT ARE AND WILL BE WORKING ON THAT.

UM, IT'S REALLY IMPORTANT TO HAVE FOLKS THAT ARE, THAT, THAT KNOW KIND OF LIKE THE GOALS THAT WE'RE WORKING TOWARDS AS A COMMUNITY SO THEY CAN HELP GUIDE, UM, DEVELOPERS TOWARDS THAT AND MAKE THE CASE FOR IT.

DO WE HAVE ANY QUESTIONS FROM FOLKS FROM TASKFORCE MEMBERS UP HERE ON THE SCREEN? OKAY.

AND I SEE THAT PERRY JOINED.

HI PERRY.

SARAH'S GOT HER HAND UP.

SARAH.

OH, PERRY HAS HIS HAND UP.

OH, THIS IS SARAH F I DON'T, I DON'T HAVE ANY SPECIFIC QUESTIONS.

THANKS FOR THE PRESENTATIONS.

AND I WOULD JUST SAY I THINK THESE ARE, UM, REALLY CRITICAL STRATEGIES THAT ARE GONNA PROVIDE A LOT OF BENEFIT.

JUST THE, YOU KNOW, ACTUAL WATER REDUCTION DEMAND, BUT ALSO, UM, COMMUNITY EDUCATION AND ADAPTATION TO OUR, OUR WATER FUTURE.

AND SO, YOU KNOW, I ENCOURAGE THE STAFF TO JUST MOVE FORWARDS WITH ALL DO HASTE AND LET'S, UM, YOU KNOW, GET TO SOME ACTIONABLE STEPS.

I THINK WITH THE, WITH ALL THE, UH, I DON'T KNOW, HANDHOLDING, I'M NOT SURE I'M TRYING TO THINK OF A BETTER PHRASE, BUT THAT JENNIFER WAS REFERRING TO.

BUT YEAH, IT'S JUST KEEP MOVING FORWARDS.

I THINK, OPPOSITION TO THAT JUST FROM A KIND OF CHANGE, YOU KNOW, MANAGEMENT KIND OF PERSPECTIVE.

YEAH, I ECHO THAT AND I THINK THAT THINKING ABOUT THOSE POLICY ISSUES, UM, YOU KNOW, SHARE WHAT THOSE SHOULD BE WITH US OR, OR WE NEED TO WORKSHOP THEM AND, AND WE SHOULD DO IT SOON IN OUR COMMITTEE MEETINGS AGAIN.

AND WE AGREE AND THANKS FOR THAT INPUT.

I, I THINK REALLY WHAT WE'RE KIND OF LAYING OUT FOR YOU TODAY IS JUST SORT OF A LITTLE BIT OF THE CHALLENGE.

I MEAN, CERTAINLY THE IDEA OF DECENTRALIZED WASTEWATER PLANNING IS, IS SOMEWHAT NOVEL.

OBVIOUSLY WE'VE BEEN A CENTRALIZED UTILITY FOR A HUNDRED YEARS, THAT'S KIND OF AT OUR CORE OF EXISTENCE AND SORT OF TRYING TO MOVE ON BEYOND THAT TO FIGURE, FIGURE OUT HOW WE APPLY THAT IN A DECENTRALIZED KIND OF PERSPECTIVE, I THINK IS IMPORTANT.

UM, REALLY HATS OFF TO A LOT OF FORWARD THINKING FOLKS, EVEN WITH THE SOUTHEAST TRAVIS COUNTY CONSENT AGREEMENT.

I MEAN, THERE'S REALLY SOME INSIGHT INTO THAT AGREEMENT THAT EXPECTED SOME REUSE IN THAT CONTEXT, WHICH WAS WAY BEFORE WE EVER EVEN THOUGHT ABOUT WATER FORWARD.

SO I JUST, I DON'T WANNA LOSE THAT.

UM, BUT I THINK REALLY WHAT WE'RE TEEING UP HERE IS THAT IN ORDER TO ALIGN, YOU KNOW, KIND OF THAT ASPIRATIONAL GOAL THAT EXISTED BEFORE WATER FORWARD, ALIGN THAT WITH WATER FORWARD, WHICH IS EVEN MORE ASPIRATIONAL IN ITS RESPECT TO, UM, WATER SUSTAINABILITY, YOU KNOW, WE'RE GONNA HAVE TO KIND OF KEEP PUSHING THAT A LITTLE BIT.

THERE WILL BE, YOU KNOW, THERE'LL BE A NATURAL,

[00:50:01]

SO IT'LL BE A COMBINATION OF STRATEGIES THAT WE'LL HAVE TO USE, NOT ONLY POLICIES, BUT PROBABLY SOME INCENTIVES, PROBABLY SOME CODES.

AND THEN WE GET RIGHT BACK INTO THAT VERY COMPLICATED MIX OF, YOU KNOW, WHAT OUR AUTHORITY IS AS A MUNICIPAL ENTITY TO IMPLEMENT CERTAIN CODE REQUIREMENTS.

SO MORE THAN YOU WANTED, BUT YOU'LL, YOU'LL GET TO HEAR A LOT OF IT ALONG, ALONG THE JOURNEY.

AND WE ANTICIPATE, OR WE HAD WANTED TO HAVE THIS AS AN INTRODUCTORY PRESENTATION, REMIND PEOPLE WHAT IS DECENTRALIZED RECLAIMED AND WHAT HAVE STAFF BEEN DOING, AND THEN WE ARE THINKING THE TEAM COULD COME BACK IN EITHER MARCH OR THE MAY TIMEFRAME IN THE SPRING TO PROVIDE AN UPDATE ON WHAT PROGRESS WE'VE MADE.

SOME OF THOSE KIND OF MAJOR TAKEAWAYS AND NEXT STEPS ARE OUTLINED ON THE LAST SIDE.

, I THINK WE KIND OF, WE, WE'VE WALKED THROUGH SOME OF THOSE, BUT WE CAN PROVIDE AN UPDATE ON WHAT OUR THINKING IS IN TERMS OF THE POLICY REQUIREMENTS, CODE CHANGES THAT MAY BE NEEDED AND OR OTHER, UM, POLICY APPROACHES ON THE PART OF THE UTILITY IN TERMS OF INFRASTRUCTURE INVESTMENT.

AND IF WE NEED TIME TO DIG INTO THOSE, LET'S DO IT IN OUR IMPLEMENTATION SUBCOMMITTEE MEETING AND SPEND SOME TIME DIGGING INTO WORKSHOPPING.

UM, I KNOW THAT VANESSA'S TIME IS SHORT HERE AND I THINK YOU HAD YOUR HAND UP OR WERE YOU JUST SAYING BYE? UM, I CAN I, I'LL ASK IT LATER.

IT'S NOT A BIG DEAL.

AND THEN DID I HEAR PERRY HAD A QUESTION AND THEN LUCIA SEE YOUR HAND.

LUCIA, GO AHEAD.

LUCIA ATHENS, OFFICE OF SUSTAINABILITY.

THIS WAS REALLY GREAT DISCUSSION AND PRESENTATION.

JUST TWO QUICK THINGS.

I KNOW WE'RE TRYING TO MOVE, MOVE ALONG ON THE AGENDA, BUT, UM, ONE, I WAS JUST CURIOUS IF COLONY PARK, UH, WAS UNDER SERIOUS CONSIDERATION FOR THESE STRATEGIES.

I KNOW WE'VE HAD SOME FOLKS WITH THE WATER UTILITY INVOLVED IN COLONY PARK DISCUSSIONS, SO JUST WANTED TO KIND OF FIGURE OUT WHAT OUR STRATEGY MIGHT BE THERE.

UM, WE CAN, YOU DON'T HAVE TO TALK ABOUT THAT HERE, BUT I'D LOVE TO FOLLOW UP ON THAT.

AND THEN SECOND, JUST I'M SURE , KEVIN AND OTHERS YOU'RE THINKING ABOUT THESE THINGS.

BUT, UM, JUST TRYING TO, UH, CAREFULLY FORMULATE OUR STRATEGY IF WE'RE GONNA GO IN THE DIRECTION OF MANDATORY REQUIREMENTS VERSUS INCENTIVIZING.

UM, THIS IS A, THIS IS A MORE, I'D SAY POLITICALLY AGNOSTIC KIND OF AN ISSUE WATER THAN, THAN CLIMATE CHANGE IS.

HOWEVER, YOU KNOW, WE REALLY, UH, HAD SOME WRENCHES THROWN IN OUR WORK TO MOVE TOWARDS NET ZERO BUILDINGS BECAUSE OF THE NATURAL GAS INDUSTRY GETTING VERY ORGANIZED ACROSS THE ENTIRE COUNTRY.

UM, AND, AND BASICALLY, YOU KNOW, THE TEXAS LEGISLATURE PAST LEGISLATION, WHICH WAS PASSED ALMOST IDENTICAL IN OTHER STATES THAT SAID IF THERE WAS A NATURAL GAS LINE ADJACENT TO A PROPERTY, WE WERE, WE CANNOT KEEP ANYBODY FROM HOOKING UP TO IT.

THIS IS SOMEWHAT DIFFERENT, BUT THERE'S JUST A LOT OF SENSITIVITIES WITH THE STATE ON LOCAL CONTROL ISSUES.

SO WE MIGHT WANNA SIT DOWN IF WE HAVEN'T ALREADY STAFF JUST SPEND SOME TIME WITH, UH, BRIEF FRANCO AND HER LEGISLATIVE TEAM TO JUST KIND OF TALK ABOUT WHAT IS THEIR READING OF THE TEA LEAVES AND TAKING OF THE PULSE, WHATEVER YOU WANNA CALL IT IN TERMS OF THE STATE'S, UM, STATE LEGISLATOR'S VIEWS ON MANDATORY REQUIREMENTS AROUND THINGS LIKE THIS.

THOSE ARE GREAT POINTS AND WE DEFINITELY, UM, HAVE OUR, UH, GOVERNMENTAL RELATIONS TEAM INTERNAL TO AUSTIN WATER, ANNA BRA BOHA, HEATHER COOK, WHO ARE DIRECTLY CONNECTED TO BRI FRANCO'S OFFICE AND HAVE THOSE CONVERSATIONS ABOUT MANY DIFFERENT TOPICS, UM, RELATED TO LOCAL CONTROL CODES AND ORDINANCES.

THAT COMES UP QUITE A BIT.

UM, AND THEN I DON'T KNOW IF KEVIN, YOU WANTED TO ADD ANYTHING TO THAT OR IF WE WANT TO SPEAK TO THE COLONY PARK QUESTION? NO, OTHER THAN WE ARE WORKING ON UTILITY SERVICE PLANS FOR RELATED TO COLONY PARK.

UM, I'LL HAVE TO GO BACK AND LOOK AT KIND OF SUSTAINABILITY, UM, ASPECTS OR OPPORTUNITIES.

I DON'T KNOW HOW FAR THEY ARE FROM THE RECLAIMED SYSTEM.

I DO KNOW, YOU KNOW, GENERALLY THEY ARE REASONABLY PROXIMATE TO THE EXISTING WATER AND WASTEWATER SYSTEM.

SO IT WOULD TEND TO, I MEAN, THE IDEA OF A DECENTRALIZED PLANT OUT THERE IS PROBABLY NOT IN THE CARDS, BUT CERTAINLY WILL LOOK INTO OPPORTUNITIES FOR, UM, OTHER SUSTAINABLE WATER SOLUTIONS.

THANK YOU WASTEWATER TEAM.

THANKS FOR HAVING US AND THANKS FOR ALL THE GREAT QUESTIONS.

IT'S NICE WHEN YOUR LAST SLIDE IS TAKEN BY QUESTIONS AND CONVERSATION AND EVERYTHING'S COVERED.

SO AWESOME.

REALLY APPRECIATE IT.

WELL, WE LOOK FORWARD TO HEARING MORE AND IT SOUNDS LIKE WE'RE GONNA BE HAVING A LOT OF DISCUSSION ON THIS, UM, AND, UH, LEARNING MORE AND FIGURING OUT WHAT THE PATH FORWARD IS TO MAKE IT ALL HAPPEN.

SO THANKS FOR COMING IN WITH SOME INTERESTING STUFF TO GET US GOING.

[00:55:01]

APPRECIATE YOUR TIME.

ANOTHER PRESENTATION FOR THAT ONE.

UM, OKAY, SO WE ARE DOING NEXT.

FILL IN THE BLANKS FOR ME, MARISA.

UM, WE CAN, HOW, HOW ABOUT WE GO TO ITEM NUMBER FIVE BECAUSE WE HAVE

[4. Update on Water Forward 2024 project status, presented by Austin Water staff • Task Progress to Date and Upcoming Milestones • Overview of Scenario Planning Approach]

UH, SARAH'S GONNA GIVE US AN OVERVIEW OF OUR SCENARIO PLANNING APPROACH AS PART OF THAT ITEM.

HOW HAS THE VOLUME LEVEL? OKAY, GREAT.

WE CAN HEAR YOU GREAT.

WE CAN TALK THROUGH THIS ONE.

UM, JUST REAL QUICKLY IF YOU GO TO THE NEXT SLIDE.

THIS IS OUR UPDATE ON OUR WATER 4 24 TASK PROGRESS TO DATE.

OUR, UM, FABULOUS WATER RESOURCES TEAM IS WORKING THROUGH MANY TASKS TO, UM, UPDATE OUR WATER FORWARD PLAN, INCLUDING COMMUNITY ENGAGEMENT.

UM, UH, WE'VE BEEN WORKING ON IDENTIFYING PRELIMINARY EQUITY, EQUITY AND AFFORDABILITY THEMES.

AND JANEL HAS BEEN WORKING WITH OUR COMMUNITY AMBASSADORS GROUP TO BEGIN COMMUNITY OUTREACH AND GATHER INPUT.

UM, ON THOSE THEMES, WE WILL ARE PLANNING TO COME BACK TO THE TASK FORCE WITH A DRAFT EQUITY AND AFFORDABILITY ROADMAP IN JANUARY, UH, FOR FURTHER DISCUSSION ON THE PLANNING METHODOLOGY.

UM, HELEN HAS BEEN, UM, WORKING WITH, UH, SARAH AND THE REST OF THE TEAM MODEL LOGIC FOR TESTING DIFFERENT COMBINATIONS OF WATER MANAGEMENT STRATEGIES AND SCENARIOS.

AND THAT SENTENCE WILL MAKE MORE SENSE AFTER SARAH'S PRESENTATION.

UM, WE ARE ALSO GONNA BE WORKING IN THE FUTURE IN DEVELOPING SOME RELIABILITY METRICS TO UNDERSTAND THE RESULTS OF OUR TESTING OF WATER MANAGEMENT STRATEGIES ON THE DEMAND FORECASTING FRONT, UH, SARAH HAS BEEN WORKING WITH OUR SYSTEMS PLANNING TEAM, OUR CITY DEMOGRAPHER, AS WELL AS, UM, MEMBERS OF OUR UTILITY DEVELOPMENT SERVICES DIVISION, UH, TO, UH, BEGIN DRAFTING OUR POPULATION AND EMPLOYMENT PROJECTIONS AND OUR NEXT STEPS THERE TO, UM, REVISE THOSE POPULATION AND EMPLOYMENT PROJECTIONS AND BEGIN INTEGRATION OF THOSE PROJECTIONS INTO OUR DISAGGREGATED DEMAND MODEL THAT, UM, WILL ALLOW US TO CREATE, UH, FUTURE WATER DEMANDS THAT WE'LL BE USING IN, UH, THIS PLANNING PROCESS.

AND THEN ON THE CLIMATE AND HYDROLOGY ANALYSIS, WE HAD A PRESENTATION ON THAT WORK IN SEPTEMBER TO THE TASK FORCE.

UM, WE HAVE BEEN WORKING WITH UT HELEN HAS BEEN, UH, WORKING WITH RICHARD AND OTHER FOLKS ON DEVELOPING THOSE, UH, STREAM FLOW SEQUENCES FOR THE CLIMATE ADJUSTED HYDROLOGY THAT WE'LL BE USING IN OUR WATER FORWARD SCENARIOS.

WE'VE ALSO CONTINUING, UH, WE ARE ALSO CONTINUING TO MEET WITH OUR CLIMATE TECHNICAL ADVISORY GROUP TO DISCUSS OUR METHODOLOGIES AND GET THEIR FEEDBACK AND INPUT.

UM, OUR NEXT STEPS ARE TO DEVELOP, UH, STREAM FLOW SEQUENCES THAT ARE, UH, UH, CREATED USING, UH, STOCHASTIC METHODOLOGY.

AND THEN WE'RE GONNA CONTINUE TO MEET WITH OUR CLIMATE TECHNICAL ADVISORY GROUP.

BUT TODAY, THE NEXT ITEM WE WANTED TO BRING UP AND, UH, APPRECIATE OUR AV FOLKS JUMPING AROUND WITH US ON PRESENTATION SLIDES.

THERE IS ANOTHER PRESENTATION FOR ITEM NUMBER FIVE, UM, THAT IS OUR SCENARIO PLANNING APPROACH.

AND SARAH IS GOING TO GIVE US AN OVERVIEW OF THAT METHODOLOGY SINCE IT IS DIFFERENT FROM THE METHODOLOGY WE USED IN THE WATER FORWARD 18, UH, PROCESS.

SO WE'LL GIVE FOLKS JUST A FEW MINUTES TO TRANSITION THOSE SLIDES AND THEN I WILL HAND IT OVER TO SARAH ETHAN AND I HAVE TO APOLOGIZE THAT I'M HERE IN PLACE OF HELEN WHO HAS BEEN THE PRIMARY DRIVER IN THIS WORK, ALTHOUGH WE'VE BEEN WORKING CLOSELY BECAUSE SHE IS GETTING A ROOT CANAL TODAY, SO SHE'S HAVING LESS FUN THAN WE ARE.

YEAH, DEFINITELY ROOT CANAL.

UM, I WAS HAPPY TO BE IN THIS SEAT INSTEAD OF HERS.

UM, SO WE ARE TALKING NOW ABOUT THE UPDATE TO OUR PLANNING APPROACH AND THE SCENARIO PLANNING APPROACH FOR THE WATER FORWARD 24 UPDATE.

HAVING A ROBUST WAY TO UNDERSTAND RISK AND UNCERTAINTY THROUGHOUT THE PLAN AND DEVELOPING A PLAN WITH A MORE COMPREHENSIVE, UM, ADAPTIVE MANAGEMENT PLAN COMPONENT.

SO THERE WERE A COUPLE OF DRIVERS COMING FROM THE PLANNING APPROACH IN WATER FORWARD 18 THAT WE REALLY WANTED TO FOCUS ON TO IMPROVE SORT OF THE, THE CLARITY AND THE ROBUSTNESS OF THE PLAN FOR THE WATER FORWARD 24 UPDATE.

ONE OF THEM IS TAKING A DIFFERENT APPROACH TO IDENTIFYING WATER NEEDS.

YOU MIGHT REMEMBER IN THE WATER FOUR 18 PLAN, THERE WERE A COUPLE OF DIFFERENT CATEGORIES OF NEEDS AND IT WAS FAIRLY COMPLEX.

UM, THE, WE'LL TALK A LITTLE BIT MORE ABOUT HOW IT'S DONE HERE, BUT IT'S, IT'S A LITTLE BIT MORE STRAIGHTFORWARD AND SIMILAR TO WHAT YOU SEE IN LIKE THE REGIONAL WATER PLANNING PROCESS.

UH, THE NEXT DRIVER IS

[01:00:01]

SO HAVING THE ABILITY TO REALLY ADAPT, UM, TO CHANGING CONDITIONS, ESPECIALLY IN THE LATER DECADES OF THE PLAN.

DO A QUESTION REAL QUICK.

YEAH, OF COURSE.

WHEN YOU SAY A CLEARER APPROACH THAN WHAT WE HAD ON WATER FOUR 18, I'M THINKING BACK LIKE THOSE TABLES THAT RICHARD MADE THAT I KIND OF ULTIMATELY UNDERSTOOD HOW, HOW TO READ THEM, BUT NOT, I COULDN'T EXPLAIN IT TO SOMEBODY ELSE.

THE NEEDS MM-HMM.

IS THAT OKAY? MM-HMM.

AWESOME.

YEAH, THERE WERE LIKE THE TYPE ONE, TYPE TWO VERY WERE TYPE THREE NEEDS.

AND IT WAS REALLY INTERESTING AND I THINK IT SHED A REALLY INTERESTING LIGHT ON THE UNIQUE NATURE OF THE NEEDS FOR AUSTIN, BUT I THINK THAT IT'S VERY COMPLICATED.

THERE ARE WAYS THAT WE CAN EXPRESS THE SAME INFORMATION BY JUST SORT OF MOVING THINGS INTO SLIGHTLY DIFFERENT CATEGORIES.

SO, SO HOPEFULLY THIS WILL BE A LITTLE BIT CLEARER WHILE MAINTAINING SOME OF THE NUANCE.

YEAH, AND I MEAN, I THINK WE ALL UNDERSTOOD IT BECAUSE WE HAD THE BENEFIT OF HAVING RICHARD EXPLAIN IT TO US, RIGHT.

WHICH HE IS ONE OF HIS SUPERPOWERS , BUT I DON'T KNOW IF I COULD HAVE EXPLAINED IT TO ANOTHER HUMAN THAT DIDN'T ALREADY KNOW ABOUT THIS, SO, ABSOLUTELY.

THAT IS, THAT'S EXACTLY RIGHT.

UM, SO WE WILL BE MAKING THAT CLEARER.

I WANNA PREPARE YOU FOR A LITTLE BIT OF HANDLING A LITTLE BIT OF COMPLEXITY IN THIS NEXT PROCESS THOUGH.

AND I'M GONNA REFER BACK TO THIS AS OUR SPAGHETTI FIGURE AND WE'LL WE'LL SEE IT LATER AGAIN.

BUT, UM, ONE OF THE, THE SCENARIO PLANNING APPROACH THAT WE'RE TAKING THIS TIME IS, IS PLANNING FOR PLAUSIBILITY VERSUS PROBABILITY.

SO AS OPPOSED TO IDENTIFYING ONE MEDIAN OR MOST LIKELY FUTURE SCENARIO, WE ARE STEPPING BACK AND, AND STARTING WITH THE UNDERSTANDING THAT WE HAVE, THIS IS DEEP UNCERTAINTY WHEREIN WE, WE CANNOT KNOW WHAT THE CLIMATE FUTURE WILL BE, WHAT THE DEMAND FUTURES WILL BE, AND WHAT THE REGIONAL SUPPLY FUTURES WILL BE.

SO THOSE ARE GOING TO BE REPRESENTED BY A RANGE OF PLAUSIBLE SCENARIOS, WHICH WILL RESULT IN A RANGE OF PLAUSIBLE NEEDS FOR THE UTILITY.

SO RATHER THAN PLANNING FOR THE ONE BLACK LINE IN THE TOP FIGURE, OUR GOAL IS TO FIND A SET OF STRATEGIES THAT PERFORM BEST OVER A BROAD RANGE OF PLAUSIBLE FUTURES.

SO THE WAY THAT THIS ACTUALLY GETS IMPLEMENTED IS BY UNDERSTANDING WHAT THAT RANGE OF, UM, OF FUTURES LOOKS LIKE BASED ON A COUPLE OF VARIABLES WHICH ARE SHOWN IN THE LITTLE GRAY BOX.

WE'RE GONNA HAVE THREE DIFFERENT AUSTIN WATER DEMAND SCENARIOS, WHICH WILL ENCOMPASS BOTH THE POPULATION AND PER CAPITA DEMAND.

UM, POSSIBLE CLIMATE FUTURES, INCLUDING DROUGHTS WORSE THAN THE DROUGHT OF RECORD.

AND SO A A BROAD RANGE OF DIFFERENT HYDROLOGY MOVING THROUGH THE PLAN, AS WELL AS SOME VARYING REGIONAL WATER SUPPLY TRENDS.

AND SO THAT WILL RESULT IN OUR OLD FAMILIAR CONE OF UNCERTAINTY.

AND OUR, OUR PLAN IS TO FIND NEAR TERM WATER MANAGEMENT STRATEGIES FOR THE FIRST 50 YEARS OF OUR HUNDRED YEAR PLAN.

OUR NEAR TERM IS 50 YEARS, RIGHT? UH, THAT PERFORM WELL OVER A BROAD RANGE OF SCENARIOS.

SO THESE ARE ROBUST STRATEGIES THAT WORK WELL, UM, AND ARE NOT PARTICULARLY SENSITIVE TO SLIGHT CHANGES IN DEMAND OR SUPPLY.

AND THEN THE SECOND 50 YEARS OF OUR HUNDRED YEAR PLAN IS, ARE THE ADAPTIVE MANAGEMENT PLAN.

SO IN THAT SECTION WE'RE REALLY JUST IDENTIFYING KEY DECISION POINTS AND SOME OF THE STRATEGIES THAT REQUIRE A LONG LEAD TIME IN ORDER TO IMPLEMENT SO THAT WE CAN ADJUST AS WE GO.

AND THIS IS ALL WITHIN THE CONTEXT OF A REGULARLY UPDATED PLAN THAT GETS REVISITED EVERY FIVE YEARS.

VERY CLOSELY WITH THE WORK THAT WAS DONE FOR MONTE MEXICO.

SO ALTHOUGH IT SEEMS LIKE IT'S, IT'S GOING TO TAKE A LITTLE BIT OF FAMILIARIZATION FOR EVERYONE TO GET COMFORTABLE WITH HAVING SO MANY DIFFERENT PLANNING SCENARIOS, THIS IS SOMETHING THAT IS BEING DONE WIDELY AND IS SORT OF AT THE LEADING EDGE, BEST PRACTICES OF SOME OF THE UTILITY WATER MODELING, UM, AROUND THE COUNTRY AND AROUND THE WORLD.

AND THESE ARE TWO EXAMPLES THAT I WON'T GET INTO TOO MUCH DETAIL, BUT I HIGHLY RECOMMEND YOU, UM, FOLLOW.

THERE ARE LINKS ON THIS PAGE TO SOME OF THE STUDIES.

OUR PROCESS ALIGNS

[01:05:01]

UM, THEY LOOKED AT THEIR, THEIR CURRENT SUITE OF STRATEGIES TO UNDERSTAND WHICH ONES WERE THE MOST ROBUST AND WHICH ONES WERE THE, UH, LOWEST COST SORT OF HIGHEST REWARD NEAR TERM STRATEGIES.

AND THEN THOSE STRATEGIES THAT WERE LESS PREFERABLE THAT THEY CALLED THEIR DEFERRED STRATEGIES, THEY SORT OF, UH, MAPPED OUT AND DID A VULNERABILITY ANALYSIS TO UNDERSTAND AT WHAT POINT THEY MAY NEED TO START PREPARING TO IMPLEMENT SOME OF THOSE STRATEGIES IN ORDER TO COMPLETE THEIR PORTFOLIO.

UM, THE METROPOLITAN WATER DISTRICT OF SOUTHERN CALIFORNIA, THEY BASICALLY TOOK THEIR EXISTING INTEGRATED WATER RESOURCES PLAN AND WHICH HAD BEEN PLANNED UP TO ONE EXPECTED FUTURE AND TESTED IT AGAINST, YOU KNOW, A RANGE OF MANY DIFFERENT WATER SCENARIOS TO UNDERSTAND WHERE THEIR VULNERABILITIES AND WHERE THEIR STRENGTHS REALLY LIE.

SO BOTH OF THOSE ARE INTERESTING CASE STUDIES AND REPRESENTATIVE OF SIMILAR WORK THAT'S BEING WIDELY PERFORMED AROUND THE WORLD.

SO WE'LL TRY TO KEEP THIS AT A PRETTY HIGH LEVEL, BUT THIS IS THE OVERVIEW OF OUR METHODOLOGY.

SO WE'RE STARTING OUT, OF COURSE WITH UNDERSTANDING WHAT OUR WATER NEEDS ARE.

AND THIS WILL BE, UM, NO TYPE ONE, TYPE TWO AND TYPE THREE.

BUT IT WILL BE A RANGE OF NEEDS BECAUSE WE HAVE A RANGE OF PROJECTED DEMANDS.

UM, AND WE'RE GOING TO LOOK AT THE PROGRESS OF WATER FORWARD 18, UM, STRATEGIES, WHICH ARE, UM, CURRENTLY BEING IMPLEMENTED TO UNDERSTAND WHAT KIND OF YIELD IS COMING FROM THOSE.

UM, AND THAT'LL RESULT IN OUR PRELIMINARY NEEDS ASSESSMENT.

AT THAT POINT, WE'RE GONNA DIG INTO THE WATER MANAGEMENT STRATEGIES, BOTH THOSE THAT WERE RECOMMENDED IN WATER FOUR AT 18.

UM, ANY SLIGHT RECONFIGURATIONS OF THOSE FROM WATER FOUR AT 18, AS WELL AS ANY ADDITIONAL ONES THAT WERE EITHER NOT SELECTED OR NOT CONSIDERED.

AND THEN THIS NEXT, UH, SORT OF, SORT OF THE THIRD BLOCK OF WORK THAT WE'RE DESCRIBING.

I'LL GET INTO A LITTLE BIT MORE DETAIL IN FUTURE SLIDES, BUT THIS IS USING THE OPTIMIZATION MODELING TO IDENTIFY MANAGEMENT STRATEGIES THAT PERFORM WELL OVER THE RANGE OF SCENARIOS.

AND THEN USING THAT INFORMATION TO BOTH CONDUCT THE, UM, CONSTRUCT 50 YEAR PORTFOLIOS FOR THAT NEAR TERM PRESCRIPTIVE PLANNING.

AND THEN ALSO USING THAT TO DO A VULNERABILITY ANALYSIS, WHICH I'LL TALK ABOUT A LITTLE BIT LATER IN A LITTLE MORE DETAIL.

AND THE RESULT OF THAT WILL BE OUR PREFERRED 50 YEAR PORTFOLIO AND AN ADAPTIVE MANAGEMENT PLAN FOR 2080 THROUGH 2120.

WHERE THEY REPEAT THE PROJECTS FROM THE FIRST 50 YEARS IN OUR SECOND 50 YEARS BECAUSE THE REGIONAL WATER PLAN IS A 50 YEAR PLAN AND OURS IS A HUNDRED.

I DO WANNA MENTION THAT WE ARE, UM, IN THE PROCESS OF GETTING CONSULTING ASSISTANCE WITH THIS, BUT BECAUSE THAT PROCUREMENT IS UNDERWAY, I CAN'T REALLY TALK ABOUT IT, BUT WE WILL HAVE HELP IN DOING THIS AND DOING ALL OF THE, THE NUMBER CRUNCHING, WHICH WILL BE WONDERFUL.

SO THE PLANNING SCENARIOS THAT WE'RE USING ARE LARGELY BASED ON THESE KIND OF THREE CATEGORIES, THE HYDROLOGIC SCENARIOS, DEMAND SCENARIOS, AND OUR REGIONAL SUPPLY SCENARIOS.

THE HYDROLOGIC SCENARIOS ARE FAIRLY SIMILAR TO WHAT WAS INCLUDED IN THE PREVIOUS PLAN WITH A COUPLE OF DIFFERENCES.

UH, WE'RE OF COURSE INCLUDING THE PERIOD OF RECORD, A PERIOD OF RECORD ADJUSTED BY CLIMATE MODELING AND THEN DROUGHTS WORSE THAN THE DROUGHT OF RECORD, UM, BASED ON SO STOCHASTIC SAMPLING FROM THE PERIOD OF RECORD.

AND THEN ANOTHER ONE BASED ON STOCHASTIC SAMPLING FROM THE CLIMATE ADJUSTED PERIOD OF RECORD.

AND THEN ONE MORE, WHICH IS DIRECT OUTPUT FROM THE GLOBAL CLIMATE MODEL SEQUENCES SAYS.

AND THOSE HYDROLOGIC SCENARIOS ARE ALSO BASED ON, I THINK WE'VE DONE SOME PRESENTATIONS OF OUR CLIMATE AND HYDROLOGY WORK, BUT ALSO BASED ON A RANGE OF CLIMATE MODELS AND UM, EMISSION SCENARIOS.

THERE WILL ALSO BE THREE AUSTIN WATER DEMAND SCENARIOS, A HIGH BASELINE AND LOWER DEMAND SCENARIO, AND THREE REGIONAL SUPPLY SCENARIOS WHICH REPRESENT ADDITIONAL WATER SUPPLY PROJECTS THAT AFFECT US ARE CLOSE ENOUGH IN THE BASIN.

UM, WE'RE BASING THOSE OFF OF THE PROJECTS THAT ARE INCLUDED IN THE REGIONAL WATER PLAN AND BASICALLY JUST ADJUSTING IMPLEMENTATION TIMING TO UNDERSTAND NOT NECESSARILY WHAT ARE LIKELY OUTCOMES, BUT TO REPRESENT A RANGE OF SORT OF REGIONAL SUPPLY SCENARIOS THAT WE WANT TO BE PREPARED FOR.

UM, ONE OF THEM INCLUDES JUST SORT OF WHAT THEY'RE PLANNING CURRENTLY FOR THE NEXT 50 YEARS TO TAKE EXACTLY THE 50 YEARS AND THEN ANOTHER SCENARIO WHERE IT TAKES A HUNDRED YEARS.

AND THEN THE THIRD SCENARIO

[01:10:01]

SO FOR ALL OF THESE, AS WE'VE MENTIONED, WE'RE NOT REALLY TRYING TO IDENTIFY WHAT IS THE MOST LIKELY, BUT TO ENSURE THAT WE'RE WE'RE REPRESENTING AN APPROPRIATE ENVELOPE OF POTENTIAL SCENARIOS.

SO WE'RE BACK TO OUR SPAGHETTI PLOT AND HOW WE ACTUALLY USE ALL OF THESE DIFFERENT STRINGS OF SPAGHETTI IN OUR PLANNING.

EFFECTIVELY, IT'S, IT'S FOCUSED ON THESE TWO DIFFERENT USES OUTLINED.

ONE OF THEM IS THE WATER MANAGEMENT STRATEGY OPTIMIZATION PROCESS AND THE OTHER IS THE VULNERABILITY ASSESSMENT.

AND I HAVE A LITTLE BIT MORE DETAIL ON THE NEXT SLIDE.

NEXT SLIDE PLEASE.

SO THE WATER MANAGEMENT STRATEGY OPTIMIZATION PROCESS, AND THIS HAS GOT A FEW, YOU KNOW, BUZZ WORDS IN HERE, NOT TO OVERWHELM OVERWHELM YOU WITH, UM, MOSTLY HELEN'S INTELLECT.

BUT, UM, THE, THE PROCESS THAT WE ARE GOING TO IMPLEMENT FOR THE WATER MANAGEMENT STRATEGY OPTIMIZATION IS WE ARE RUNNING MANY OF THE POTENTIAL WATER MANAGEMENT STRATEGY COMBINATIONS THROUGH ALL OF THOSE, WHAT IS IT? 639 DIFFERENT SCENARIOS.

AND BECAUSE THE WHAM UM, THE ACTUAL MODEL IS A FAIRLY CLUNKY MODEL, WE'RE DEVELOPING WHAT WE'RE, WHAT WE'VE NAMED THE MINI WHAM, WHICH IS A LITTLE BIT MORE EFFICIENT MODEL, WHICH WE CAN USE TO, TO RUN AGAINST NUMEROUS SCENARIOS SO THAT WE CAN HAVE JUST A MUCH LARGER VOLUME OF OUTPUT AND A MUCH LARGER VOLUME OF DATA.

AND THAT THOSE MINI WHAM RUNS BASICALLY A MASS BALANCE MODEL FOR THE HIGHLAND LAKES, UM, WITHOUT A TON OF DETAIL, BUT, UM, OPTIMIZED IN ORDER TO SHOW US WHAT RESULTS WE NEED TO SHOW AND HAVE A MODEL THAT CAN INTEGRATE WITH THIS BO OPTIMIZATION ALGORITHM, WHICH IS SORT OF THE INDUSTRY STANDARD, YOU KNOW, LEADING EDGE WATER RESOURCES MODELING PLATFORM.

SO THAT WILL HELP US TO IDENTIFY WHICH STRATEGIES PERFORM WELL OVER A, A BROAD RANGE OF SCENARIOS.

AND THE METRICS THAT WE'RE USING TO, UM, IDENTIFY SUCCESSFUL STRATEGIES AND SUCCESSFUL COMBINATIONS OF STRATEGIES IS RELIABILITY, RESILIENCY, AND VULNERABILITY.

SO UNDERSTANDING THE DURATION, UM, FREQUENCY AND SEVERITY OF WATER SHORTAGES IN ORDER TO IDENTIFY WHICH STRATEGIES HAVE THE, THE BEST ABILITY TO MEET PROJECTED GOALS.

UH, I THINK YOU'RE STILL ALLOWED TO TELL ME THAT IT WAS A GOOD PRESENTATION.

SO THE SECOND USE OF OUR MULTIPLE SCENARIOS IS A VULNERABILITY ANALYSIS.

AND THIS IS REALLY FOCUSED MORE ON OUR SECOND, THE SECOND 50 YEARS OF OUR PLANNING HORIZON.

AND SO THIS IS IDENTIFYING BOTH SUPPLY RELATED AND DEMAND RELATED CONDITIONS OR SCENARIOS THAT SHOW US PRETTY CONSISTENTLY LEAVING LEADING TO FAILURE.

SO FOR INSTANCE, IF WE HAVE, YOU KNOW, TRENDING VERY HIGH IN DEMAND, HIGHER THAN ANTICIPATED AND THE CLIMATE TREND SEEMS TO BE TOWARD DRY, THEN WE'VE IDENTIFIED MAYBE A TIME WHEN WE NEED TO START LOOKING AT THE MORE AGGRESSIVE WATER MANAGEMENT STRATEGY IMPLEMENTATION PATHWAY.

OR FOR INSTANCE, IF WE HAVE A REALLY, UM, A REALLY HIGH DEMAND AND A REALLY DRY CLIMATE SCENARIO THAT'S PROBABLY NOT GONNA LEAD US ON A PATHWAY THAT HAS AN OFF CHANNEL RESERVOIR, IT MIGHT LEAD US TO A SUPPLY WHICH IS A LITTLE BIT MORE DROUGHT RESISTANT.

SO THIS WILL GUIDE US TO APPROPRIATE PROJECTS FOR THE FUTURE BASED ON THOSE SIGNPOSTS.

AND ALSO IS A GOOD TIME TO SORT OF THINK ABOUT THE LEAD TIME THAT'S REQUIRED FOR ALL THOSE PROJECTS BECAUSE ANY OF THEM ARE, YOU KNOW, GONNA BE A SIGNIFICANT UNDERTAKING IF WE PUT THEM IN THE DEFERRED CATEGORY.

THEY'RE NOT OUR LOW HANGING FRUIT PROJECTS.

SO THEY UM, REQUIRE A FAIR AMOUNT OF LEAD TIME.

SO THIS GIVES US AN OPPORTUNITY TO UNDERSTAND AT WHAT POINT WE NEED TO BE REALLY CONSIDERING, UH, YOU KNOW, PURSUING WHATEVER THE STRATEGY MAY BE.

AND I BELIEVE THAT THAT IS OUR LAST SLIDE.

SO QUESTIONS? GREAT JOB.

WE LOST THE FORUM.

OH,

[01:15:01]

THAT WAS A VERY GOOD PRESENTATION.

NOT, AND YOU HAVE RECOMMENDED THAT HE LOGGED OFTEN LOG BACK ON IT.

I BET THAT'S WHAT HE IS DOING.

HAT IF THEY COULD, UM, RESTART THE COMPUTER CAUSE THEY COULDN'T GET THEIR VIDEO THROUGH.

CAUSE PERRY TEXTED ME DURING THIS PRESENTATION SAYING HE STILL WASN'T ABLE TO GET ON AND HE SAID HE JUST SAW YOUR EMAIL, SO I BET HE'S DOING THAT RIGHT NOW.

THERE HE IS, HE'S JOINED AND SO WE JUST NEED HA I SUMMED HIM 1, 2, 3, 4, 5.

WE JUST NEED HA BACK AND HOPEFULLY HE'LL BE JOINING SOON.

HEY PERRY, WE CAN DO EVERYTHING EXCEPT GET ON VIDEO.

I'VE BEEN HERE THE WHOLE TIME, BUT JUST, LET'S SEE, WE HAVE HA BACK AS WELL.

TO, SORRY PERRY.

I KNOW THAT'S SO FRUSTRATING.

CAN WE HEAR HAITI? DO WE HAVE A QUORUM? YEP.

SORT OF.

WE DON'T HAVE VIDEO.

OH, WELL I MEAN, PERRY'S BEEN TRYING TO GET ON VIDEO THE WHOLE TIME AND IT'S NOT WORKING, SO I THINK IT'S FINE UNLESS SOMEBODY TELLS ME SO WELL BEFORE WE HAD, UH, SARAH AND VANESSA, UM, BUT NOW THEY'RE GONE.

YAY.

VERY GOOD PRESENTATION OFFICIALLY.

ALL RIGHT, SO WE'RE GOOD QUESTION.

WELL DONE.

UM, YEAH, APPRECIATE THE, APPRECIATE THE REFERENCES, UM, TO, YOU KNOW, MONTEREY AND METROPOLITAN WATER DISTRICT.

UM, AND I GUESS WHEN WE'RE LOOKING AT A, AT A RANGE THAT YOU WERE SHOWING AND I THINK THAT YOU WERE, THAT WAS JUST AN EXAMPLE OF A SPAGHETTI, SPAGHETTI PLOT.

UM, THAT THAT DOES STILL ALLOW YOU TO DO STATISTICS I GUESS IN TERMS OF, YOU KNOW, AIMING FOR THE MEDIAN, BUT THEN ALSO, UM, LIKE IF YOU WANTED TO, TO HAVE STRATEGIES THAT WORKED OUT OVER THAT WHOLE RANGE, YOU ARE PRETTY MUCH THEN PREPARING FOR THE WORST ONE OF ALL OF THOSE.

BUT, BUT I GUESS THERE'S ALSO THE ABILITY TO SAY, YOU KNOW, WE'RE, WE'RE PREPARED AT A 90% CERTAINTY LEVEL AND YOU KNOW, LOOKING AT THE MONTEREY, I'M GETTING TOO OLD TO SEE TEXAS LOW, BUT IT'S UH, UM, YOU KNOW, IT'S A GOOD PLOT CUZ IT SHOWS THE GREATER RESILIENCY YOU WANT, PARTICULARLY WITH THE UNCERTAINTY, UM, THE MORE IT COSTS.

AND, AND IT SAYS ON ON ONE AXIS THE RELIABLY RELIABILITY OR RESILIENCY REGRET AND TOTAL INVESTMENT COST REGRET , IS THAT WHAT IT SAYS? YES.

HOPEFULLY WE DON'T HAVE TOO MANY REGRETS.

TOO MANY REGRETS.

UM, I DO WANNA, YEAH, I DIDN'T NECESSARILY GO INTO TOO MUCH DETAIL, BUT THE WAY THAT WE ARE LOOKING AT PLANNING TO THE WHOLE RANGE OF SPAGHETTI IS ALSO, UM, UNDERSTANDING WHAT RISKS WE FIND TO BE ACCEPTABLE SO WE CAN CATEGORIZE ALL OF THOSE DIFFERENT NEEDS PROJECTIONS AND WE CAN EITHER CATEGORIZE THEM ON THE HYDROLOGY FROM WHICH THEY'RE ORIGINATED OR WE COULD USE OTHER METRICS AND STATISTICAL MEASURES TO CATEGORIZE THEM AND SAY THAT MAYBE WE WANT TO BE 90% RESILIENT TO THESE MOST EXTREME EVENTS, BUT WE ABSOLUTELY MUST BE ABLE TO, YOU KNOW, MEET ALL OF OUR GOALS WITH ANY PERIOD OF RECORD HYDROLOGY OR, YOU KNOW, WE CAN, WE CAN SORT OF THOUGHTFULLY DEVELOP OUR OWN ASSESSMENT OF RISK AND, AND DECIDE HOW RISK AVERSE OR, UM, YOU KNOW, MAYBE MORE COST SENSITIVE BEING KIND OF THE PRESSURE IN THE OTHER DIRECTION.

, WE WANNA BE, AND I GUESS THERE'S INTERPRETATION ON WHAT'S A, WHAT EXACTLY IS A PLAUSIBLE FUTURE OR NOT.

UM, UM, EACH OF US PROBABLY HAS OUR OWN THRESHOLDS THERE, BUT, BUT, UM, UM, I'M GLAD TO SEE THAT THE CITY IS I GUESS LOOKING AT A RANGE OF CLIMATIC MM-HMM.

, UM, POTENTIAL FUTURES.

UM, CAUSE I DO STILL FEEL LIKE OUR CPA 0.5 WAS MAYBE TOO HARDCORE.

RIGHT.

ALSO RECOGNIZE THAT, UH, UM, ENGINEERS LIKE TO BUILD A SAFETY FACTOR AS WELL, SO.

WELL, AND PART OF I THINK THE GOAL IN LOOKING AT THE SPAGHETTI PLOT IS THAT IN SOME WAYS WHETHER WE HAD ARRIVE AT A HIGHER NEEDS SCENARIO BECAUSE OF AN EMISSION SCENARIO OR BECAUSE OF SOME OTHER SUPPLY IMPACT, REGIONAL GROWTH OR, YOU KNOW, ALL OF THESE DIFFERENT CAUSES MAY STILL GET US TO THE SAME NEEDS ASSESSMENT AND THAT STILL MAKES IT, YOU KNOW, A PLAUSIBLE PUTS IT WELL WITHIN THE ENVELOPE OF LIKELY SCENARIO, NOT NECESSARILY LIKELY PLAUSIBLE SCENARIOS THAT WE WANT TO BE PREPARED

[01:20:01]

FOR.

IT'S JUST KIND OF SETTING THOSE EXPECTATIONS AROUND THE RELIABILITY METRICS AND WHAT METRICS ARE IMPORTANT FOR US TO PAY ATTENTION TO WHAT LEVEL OF RISK WE'RE WILLING TO ACCEPT.

THAT'S ALWAYS THE QUESTION WITH THIS.

UM, I KNOW, I KNOW THAT TODD HAS TO LEAVE SOON, SO, UM, DO WE HAVE ANY OTHER QUESTIONS ON THIS? AND I WANTED TO TALK ABOUT OUR NEXT MEETING IN QUORUM.

SARAH, THANK YOU VERY MUCH.

THANK YOU FOR HAVING CONVERSATION AND WE'RE GONNA NOT DO AGENDA ITEM THREE, WE'RE NOT MAKING IT TO THAT ONE.

THAT, AND THAT'S FINE.

SO JUST OUR NEXT MEETING WE HAVE ESPECIALLY CALLED, UM, MEETING, I'M LOOKING AT THE WRONG APPOINTMENT.

[FUTURE AGENDA ITEMS]

ON MONDAY THE 12TH, UM, OF DECEMBER FROM 12 TO TWO.

IT'S UH, GONNA BE A HYBRID MEETING.

I'M NOT SURE WHERE IT'S GONNA, IS IT GONNA BE HERE? YES, WE BELIEVE SO.

SO, UM, WE'RE, WE'RE PRETTY SLIM ON MEMBERS AND REACHING QUORUM RIGHT NOW, SO I JUST, IF ANYONE HAS ANY KIND OF, UM, ISSUES WITH BEING AT THAT MEETING, PLEASE LET US KNOW SOONER RATHER THAN LATER.

I'M FLYING BACK TO AUSTIN LATE SUNDAY NIGHT AND I WILL HOPE THAT THE SOUTHWEST GODS ARE ON MY SIDE THE SOUTHWEST AIRLINES GODS THAT IS.

UM, AND SPEAKING OF MEMBERSHIP, I KNOW THAT WE'VE GOT COUNCIL ELECTIONS COMING UP AND, AND WE'VE GOT A LOT OF OPEN SPOTS AND THIS IS NOT THE TIME TO GET FOLKS ATTENTION TO FILL VACANCIES.

UM, AND I, SOME PEOPLE MAY BE STAYING ON OR GETTING OFF, SO WE'RE GONNA HAVE DEFINITELY SOME CHURN HERE COMING UP.

UH, I, I IMPLORE EVERYONE TO THINK VERY MUCH ABOUT LETTING US KNOW IF YOU'RE GONNA BE STAYING ON THE TASK FORCE, WHICH I HOPE EVERYBODY IS AND HOW WE AND, AND WHO WE KNOW IN OUR COMMUNITY THAT MAY WANT TO, UM, SERVE WITH THIS WONDERFUL GROUP OF PEOPLE ON THIS AWESOME TOPIC.

UM, AND SO WE CAN GET ALL, WE CAN HAVE FULL MEMBERSHIP FOR THE COMMITTEE GOING INTO 2023 WOULD WAS, WOULD BE REALLY GOOD AND THEN GIVE PEOPLE A LITTLE MORE FLEXIBILITY.

ANY OTHER ANNOUNCEMENTS WE NEED? UM, ANY FUTURE AGENDA ITEMS WE NEED TO TALK ABOUT? WE HAVE THAT SPECIAL MEETING, WHAT'S THAT GONNA BE ABOUT? YES.

UH, SO ON DECEMBER 12TH, A COUPLE OF THINGS WE'RE GONNA BE TEEING UP.

WE WANT TO PRESENT THE UPDATED POPULATION AND EMPLOYMENT PROJECTIONS, UM, THAT THE TEAM HAS BEEN WORKING ON.

SARAH EMAN HAS BEEN LEADING A LOT OF THAT WORK.

AND THEN WE WILL ALSO HAVE A BRIEF PRESENTATION FROM OUR EQUITY OFFICE ON THE EQUITY TOPIC, GIVING A HIGH LEVEL OVERVIEW.

AND THAT'S, UH, TO SET US UP FOR SUCCESS IN JANUARY AS WE'RE REVIEWING OUR EQUITY AND AFFORDABILITY ROADMAP FOR THE PLAN.

WONDERFUL.
