Approach

• Growth predictions based on past growth are sensitive to the time frame selected

• Understanding growth drivers and basing analysis on interpretation of these is necessary

• Risk factors for population growth must be included

Freeland Areas

Zip-code 98249 Freeland CDP Freeland NMUGA

Page 17: Freeland Water and Sewer District Citizens Advisory Committee Preliminary Report Freeland Population and Growth Study Environmental Issues Proposed Sewer

Freeland 98249 facts

• 2010 population 4561• 34.4% (1540) of the population are drawing

social security• 27.7% (1244) are employed• Average income per person $37,915• Average Age 54.9• Average growth from 2000 to 2010 was 2.3%/yr• Growth from 2010-2011 is 0.37%

FWSD

Cumulative Water Connections

Page 20: Freeland Water and Sewer District Citizens Advisory Committee Preliminary Report Freeland Population and Growth Study Environmental Issues Proposed Sewer

FWSD/HHSD

• 2004-2009 – FWSD

• 6 new residential water connections (0.26%/yr)• 84 new commercial water connections (8.26%/yr)

– HHSD• 156 residential sewer connections (8 %/yr)

• 2009-2011 – FWSD

• 1 new residential water connection (0.11%/yr)• 4 new commercial water connections (0.45%/yr)

– HHSD• 6 residential sewer connections (0.8%/yr)

Page 22: Freeland Water and Sewer District Citizens Advisory Committee Preliminary Report Freeland Population and Growth Study Environmental Issues Proposed Sewer

Freeland NMUGA

• No 2000 census• 2010 population is 1633• 879 of Freeland NMUGA residents, 54%, are

served by HHSD and MSSD sewer districts• 675 of Freeland NMUGA residents (@2.11 per

household), 41%, are served by the FWSD• 79 of Freeland NMUGA residents, 5%, are on

wells and not presently served by any district

Page 23: Freeland Water and Sewer District Citizens Advisory Committee Preliminary Report Freeland Population and Growth Study Environmental Issues Proposed Sewer

Growth in Freeland NMUGA

• Freeland CDP used as Freeland NMUGA proxy• 1313 to 2045 residents from 2000 to 2010 • 732 new CDP residents from 2000 to 2010• 456 of these were in HHSD or MSSD• This results in an increase of 277 (growth from

1313 to 1579) in the area a FWSD sewer might serve (1.9%/yr)

Page 24: Freeland Water and Sewer District Citizens Advisory Committee Preliminary Report Freeland Population and Growth Study Environmental Issues Proposed Sewer

OFM data 2010 to 2011

• Growth rates from 2010 to 2011(OFM data)– Island County -2.5%– Coupeville 1.31%– Langley 0.87%– Freeland UGA 0.36%

Page 25: Freeland Water and Sewer District Citizens Advisory Committee Preliminary Report Freeland Population and Growth Study Environmental Issues Proposed Sewer

Business Growth

• Freeland has shown business growth in excess of population growth especially from 2004 to 2008, but continuing at a slower rate in more recent years

• The Chamber of Commerce has not provided any meaningful input to this study

• Continued business growth is expected, but no specific rate is known

Page 26: Freeland Water and Sewer District Citizens Advisory Committee Preliminary Report Freeland Population and Growth Study Environmental Issues Proposed Sewer

Conclusions

• Previous yearly population growth was as high as 4%

• Current yearly population growth is under 1%• Until the economy recovers the population

growth in the Freeland NMUGA will remain stagnant and there are no indicators supporting a near term recovery

Page 27: Freeland Water and Sewer District Citizens Advisory Committee Preliminary Report Freeland Population and Growth Study Environmental Issues Proposed Sewer

Environmental Issues

Page 28: Freeland Water and Sewer District Citizens Advisory Committee Preliminary Report Freeland Population and Growth Study Environmental Issues Proposed Sewer

Issues

• Fecal Coliform / shellfish protection / Freeland Beach

• Low dissolved oxygen in Holmes Harbor

Page 29: Freeland Water and Sewer District Citizens Advisory Committee Preliminary Report Freeland Population and Growth Study Environmental Issues Proposed Sewer

Program for Fecal Coliform

• Pet waste• Livestock• Low impact development (surface water)• Natural yard Care Meetings• Septic inspections– 98% in Holmes Harbor– 14% in Island County

Page 30: Freeland Water and Sewer District Citizens Advisory Committee Preliminary Report Freeland Population and Growth Study Environmental Issues Proposed Sewer

DNA in Nisqually Inlet• Conclusions of DNA-Typing Study• • The number of isolates matched (89%) exceeded anticipated results.• • Birds are the dominant source seen overall.• • Cows are the second most frequent source in actively grazed

agricultural fields.• • After birds, canine and rodents (wildlife) are predominant at sites

where there is limited human activity.• • Human sources are second most frequently seen source at the

residential sites and are present where hunting is leased.• http://

• Note: With over 1,000,000 FC/ml, we are not the “dirtiest” beech

Page 31: Freeland Water and Sewer District Citizens Advisory Committee Preliminary Report Freeland Population and Growth Study Environmental Issues Proposed Sewer

Septic Inspections

• The CAC discussed septic inspections and suggests the County should prioritize inspections of very old systems near the water

• It is not true that properly designed and maintained septic systems do not function properly year round in the Freeland area

Report Conclusions

Next Steps• Finalize ECY Report: Due June 30, 2012 with a Post Project Assessment in 2015• Partner with DOH to share results and work towards removing closure area

Page 34: Freeland Water and Sewer District Citizens Advisory Committee Preliminary Report Freeland Population and Growth Study Environmental Issues Proposed Sewer

Low dissolved oxygen

• Whidbey action area

Page 36: Freeland Water and Sewer District Citizens Advisory Committee Preliminary Report Freeland Population and Growth Study Environmental Issues Proposed Sewer

Proposed Sewer System

Page 37: Freeland Water and Sewer District Citizens Advisory Committee Preliminary Report Freeland Population and Growth Study Environmental Issues Proposed Sewer

Commercial Core Options

• The system we examined covered the commercial core on the north side of Hwy 525, however an extension to the south side could be added

Page 38: Freeland Water and Sewer District Citizens Advisory Committee Preliminary Report Freeland Population and Growth Study Environmental Issues Proposed Sewer

Options for Disposal

• Trillium property was dismissed as an option– Cost over $6.5 million before additional storage

and easements/drainage ditches required by hydro-study

– The operational costs were $60,000/year– The was virtually no recharge of the aquifer, but

the water went to transpiration or ran off downhill potentially exacerbating a present flooding problem (potential for legal actions)

Page 39: Freeland Water and Sewer District Citizens Advisory Committee Preliminary Report Freeland Population and Growth Study Environmental Issues Proposed Sewer

Options for Disposal

• Outfall into Admiralty Inlet– Will require studies and permits– Unlimited capacity

• Constructed wetlands discharging into Holmes Harbor– Potential wetlands park– Potential roadblock (Pinto Creek case)

• Local drain-fields (as Main street SD)– If systems are less than 100,000 gallons/day only DOH

permits necessary– Capacity limited – but lots of open space– All options would include available reuse water

Page 40: Freeland Water and Sewer District Citizens Advisory Committee Preliminary Report Freeland Population and Growth Study Environmental Issues Proposed Sewer

Treatment

• Membrane bio-reactor (MBR) systems located at:– Homes Harbor SD plant– Main Street SD plant– Other central location(s)

Page 41: Freeland Water and Sewer District Citizens Advisory Committee Preliminary Report Freeland Population and Growth Study Environmental Issues Proposed Sewer

Proposed Project Scope

• In the near term, the only potential need for sewers is in the commercial core

• Any development of sewers in residential areas is not justified at present either to meet residential growth requirements or for environmental reasons

• Septic systems are allowed within a comprehensive sewer plan and are GMA compliant

Page 42: Freeland Water and Sewer District Citizens Advisory Committee Preliminary Report Freeland Population and Growth Study Environmental Issues Proposed Sewer

What’s Next?

• Cost estimates for three basic alternatives (waiting for the revised versions)– Holmes Harbor treatments and outfall– Local treatment (new or MSSD) and constructed

wetlands– Local treatment (new or MSSD) and multiple drain

fields • Determine if there is support from the commercial

core• Revise the FWSD Sewer Plan
