PROJECT OBJECTIVES

A NEW RESERVOIR IS NEEDED IN THE HIGH SYSTEM PRESSURE ZONE:

  • TO INCREASE SYSTEM RELIABILITY – FIRE FLOW

& PEAK DEMAND SUPPLY DURING THE SUMMER

  • TO MEET WASHINGTON STATE DEPARTMENT

LOCATION SELECTION

Near center of pressure zone Close to transmission main

slide-9
SLIDE 9

LOCATION SELECTION

Near center of pressure zone Close to transmission main Above about 2380 Note: land slopes downhill north of 29th Ave and is therefore too low for a tank.

Our Lady Of Fatima

Criteria Met Close to existing t-main yes Nr center of pressure zone yes At or above 2380 yes Vacant land min 1 ac barely Relatively flat yes City owned no Distant from nearby homes no Other: tank would be large impact to this small area, no guarantee it could be acquired, very close to adjacent homes

SE Blvd

Criteria Met Close to existing t-main yes Nr center of pressure zone yes At or above 2380 yes Vacant land min 1 ac yes Relatively flat no City owned no Distant from nearby homes no Other: steeply sloped small property would result in high construction costs, substantial rock removal, this property likely is best used as commercial, no guarantee it could be acquired

CONCLUDING THOUGHTS

  • THIS TANK IS AN IMPROVEMENT THE CITY HAS TO MAKE
  • IF YOU LIVE ANYWHERE SOUTH OF 14TH AVE., YOU BENEFIT
slide-44
SLIDE 44

CONCLUDING THOUGHTS

  • THIS TANK IS AN IMPROVEMENT THE CITY HAS TO MAKE
  • IF YOU LIVE ANYWHERE SOUTH OF 14TH AVE., YOU BENEFIT
  • EVERY LOCATION PRESENTED TONIGHT WILL BE CONTROVERSIAL
  • THE RESERVOIR MUST BE LOCATED IN THE VICINITY OF HAMBLEN PARK AND

SO WILL BE VISIBLE FROM THIS AREA REGARDLESS OF LOCATION

CONCLUDING THOUGHTS

  • EVERY LOCATION PRESENTED TONIGHT WILL BE CONTROVERSIAL
  • THE RESERVOIR MUST BE LOCATED IN THE VICINITY OF HAMBLEN PARK AND

SO WILL BE VISIBLE FROM THIS AREA REGARDLESS OF LOCATION

  • HAMBLEN PARK MEETS ALL THE CRITERIA
  • HAMBLEN DOESN’T DISPROPORTIONATELY IMPACT SOME NEIGHBORS

BECAUSE IT’S A BLOCK AWAY FROM THE NEAREST HOME

BECAUSE IT’S A BLOCK AWAY FROM THE NEAREST HOME

  • THE COMPLETED TANK IMPACTS LESS THAN 1% OF THE AREA IN HAMBLEN
  • PARK. THE PARK WILL NOT BE LOST OR DESTROYED AS SOME FEAR.
  • A TANK IN HAMBLEN PARK IS AN OPPORTUNITY TO END UP WITH

COMMUNITY ASSETS WHICH WOULD NOT BE REALIZED AT OTHER LOCATIONS

slide-49
SLIDE 49

QUESTION & COMMENTS

  • COMMENT/QUESTION: THE PROPOSED TANK WILL SEVERELY IMPACT THE
  • PARK. HOW MUCH OF THE PARK WILL BE IMPACTED?
slide-50
SLIDE 50

QUESTION & COMMENTS

  • COMMENT/QUESTION: THE PROPOSED TANK WILL SEVERELY IMPACT THE
  • PARK. HOW MUCH OF THE PARK WILL BE IMPACTED?
  • RESPONSE: AS WE’VE ATTEMPTED TO COMMUNICATE IN THIS PRESENTATION,

WE DO NOT TAKE LOCATING THIS TANK IN THE PARK LIGHTLY. WE’VE COVERED TONIGHT THE 10 OTHER SITES CONSIDERED AND THE SUBSTANTIAL DISADVANTAGES OF EACH. RECALL THAT LESS <1% OF THE TOTAL PARK AREA WILL BE CONSUMED BY THE PROPOSED TANK. THE TEMPORARY CONSTRUCTION IMPACT OF THIS TANK AFFECTS A LARGER AREA, APPROX. 1 ACRE OR 12% OF THE SITE. THAT IMPACTED AREA WILL BE REPLANTED AND RESTORED IMMEDIATELY FOLLOWING CONSTRUCTION.

QUESTION & COMMENTS

  • COMMENT/QUESTION: IF THIS TANK DOES END UP BEING IN HAMBLEN PARK,

PLEASE DON’T “IMPROVE” THIS PARK. WE LIKE IT JUST THE WAY IT IS.

SLIDE 52

QUESTION & COMMENTS

  • COMMENT/QUESTION: IF THIS TANK DOES END UP BEING IN HAMBLEN PARK,

PLEASE DON’T “IMPROVE” THIS PARK. WE LIKE IT JUST THE WAY IT IS.

  • RESPONSE: WE HAVE RECEIVED THIS COMMENT FROM A NUMBER OF PEOPLE.

WE HAVE ALSO RECEIVED THE OPPOSITE COMMENTS FROM A NUMBER OF

  • PEOPLE. WE LOOK FORWARD TO REVIEWING THE SURVEY RESULTS TO SEE

WHAT THE MAJORITY OF PEOPLE WAY ON THIS ISSUE. THE CITIZENS WILL GUIDE OUR MITIGATION MEASURES. PARK IMPROVEMENTS DO NOT NECESSARILY MEAN DEVELOPING THE PARK.

slide-53
SLIDE 53

QUESTION & COMMENTS

  • COMMENT/QUESTION: IS “IMPACTS TO THE PUBLIC” ONE OF THE SITE

SELECTION CRITERIA?

slide-54
SLIDE 54

QUESTION & COMMENTS

  • COMMENT/QUESTION: IS “IMPACTS TO THE PUBLIC” ONE OF THE SITE

SELECTION CRITERIA?

  • RESPONSE: YES, IT IS.
  • ONLY CONSIDERING VACANT PARCELS (AS OPPOSED TO BUYING HOMES AND

DEMOLISHING HOUSES) IS ONE WAY TO REDUCE THE IMPACT TO PUBLIC.

  • FAVORING A RESERVOIR SITE WHICH IS AT LEAST 300’ FROM THE NEAREST

ADJACENT HOME IS ANOTHER WAY TO REDUCE IMPACTS TO THE PUBLIC.

  • SELECTING A SITE WHICH REDUCES COSTS WE ALL HAVE TO PAY IS YET ANOTHER

WAY TO REDUCE IMPACTS TO THE PUBLIC.

  • PLACING THE TANK CENTRALLY IN A TREED AREA ALSO REDUCES THE VISUAL

IMPACT TO THE PUBLIC.

slide-55
SLIDE 55

QUESTION & COMMENTS

  • COMMENT/QUESTION: WAS THE POTENTIAL REDUCTION IN PROPERTY VALUES

ONE OF THE CONSIDERATIONS FOR TANK SITE SELECTION?

slide-56
SLIDE 56

QUESTION & COMMENTS

  • COMMENT/QUESTION: WAS THE POTENTIAL REDUCTION IN PROPERTY VALUES

ONE OF THE CONSIDERATIONS FOR TANK SITE SELECTION?

  • RESPONSE: ONE OF THE CRITERIA IS TO LOCATE THIS TANK AWAY FROM

ADJACENT HOMES TO THE MAXIMUM EXTENT POSSIBLE TO REDUCE IMPACTS INCLUDING ANY POTENTIAL IMPACTS TO PROPERTY VALUES. HAMBLEN PARK IS THE LOCATION THAT PLACES THE PROPOSED TANK FURTHER FROM ADJACENT RESIDENTS THAN ANY OTHER ALTERNATIVE WHILE STILL ACCOUNTING FOR COST CONSIDERATIONS.

QUESTION & COMMENTS

  • COMMENT/QUESTION: HAS AN ENVIRONMENTAL REVIEW BEEN PERFORMED

YET? HAS A TREE PRESERVATION/REPLACEMENT PLAN BEEN DEVELOPED?

slide-58

QUESTION & COMMENTS

  • COMMENT/QUESTION: HAS AN ENVIRONMENTAL REVIEW BEEN PERFORMED

YET? HAS A TREE PRESERVATION/REPLACEMENT PLAN BEEN DEVELOPED?

  • RESPONSE: NO, THIS WILL OCCUR ONCE SITE SELECTION HAS BEEN FINALIZED.

QUESTION & COMMENTS

  • COMMENT/QUESTION: HAVE YOU CONSIDERED VARIOUS COLOR SCHEMES

OR A MURAL TO REDUCE VISUAL THE IMPACTS TO THIS TANK.

slide-60
SLIDE 60

QUESTION & COMMENTS

  • COMMENT/QUESTION: HAVE YOU CONSIDERED VARIOUS COLOR SCHEMES

OR A MURAL TO REDUCE VISUAL THE IMPACTS TO THIS TANK.

  • RESPONSE: THOSE EVALUATIONS WILL BE PERFORMED WITH COMMUNITY

INPUT FOLLOWING FINALIZATION OF TANK SITE SELECTION. AS YOU SUGGEST, THERE ARE A NUMBER OF OPTIONS FOR REDUCING THE VISUAL IMPACTS.

slide-61
SLIDE 61

QUESTION & COMMENTS

  • COMMENT/QUESTION: WILL CELL PHONES ANTENNAE AND/OR AIRCRAFT

WARNING LIGHTS BE INSTALLED ATOP THIS TANK.

slide-62
SLIDE 62

QUESTION & COMMENTS

  • COMMENT/QUESTION: WILL CELL PHONES ANTENNAE AND/OR AIRCRAFT

WARNING LIGHTS BE INSTALLED ATOP THIS TANK.

  • RESPONSE: YES, AIRCRAFT WARNING LIGHTS MUST BE INSTALLED. CELL

PHONE ANTENNAE INSTALLATION WILL NOT BE A PART OF THIS PROJECT. CELL PHONE COMPANIES DESIRING TO PUT ANTENNAE ATOP THIS TANK WILL HAVE TO COMPLY WITH A SEPARATE PERMITTING PROCESS THAT IS NOT RELATED TO TANK CONSTRUCTION.
