    Preliminary Report Freeland Population and Growth Study Environmental Issues Proposed Sewer Options
  2. Freeland Population and Growth Study

  3. Data sources used for this report Washington State OFM/Island County data Washington Regional Economic Analysis data Port of South Whidbey South Whidbey School District data Freeland Water and Sewer District data Holmes Harbor Sewer District data Washington State DOT data Washington Department of Commerce, Bureau of Economic Analysis Trulia Real estate data
  4. 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
  5. Island County OFM Since 2005 there is declining growth in population
  6. Washington Regional Economic Analysis data A clear trend in declining growth rate
  7. Washington Regional Economic Analysis data
  8. Washington Regional Economic Analysis data
  9. Island County personal income compared to Washington State
  10. Island County and Washington State per capita Income compared to USA Note recent trends
  11. Port of South Whidbey data South Whidbey population vs. year
  12. South Whidbey School District1999-2010 The South Whidbey School District enrollment in 2010 is 64% of the 1999 enrollment (dropping by over 3.5%/year over the last decade) and is predicted to decline by an additional 300 students (20%) by 2016.
  13. Why the declining enrollment- changing demographic in South Whidbey Freeland (98249) 2000 2010 Median age 46.7 54.9 Average household size 2.29 2.09 Oak Harbor (98277) Median age 30.4 33 Average household size 2.67 2.5 Clinton Median age 43.4 51.2 Average household size 2.47 2.25
  14. Income comparison with Oak Harbor Freeland - 2497 tax filers Oak Harbor - 17022 tax filers Freeland has a higher percentage of high income tax filers, but also a higher percentage of lower income tax filers.
  15. Clinton/Mukilteo Ferry ridership Study with data to 2006 (before economic downturn) showed an increase of 4.3%/yr Ridership has declined 4.8% since 2006, 2.5% in 2009-2010
  16. Freeland Areas Zip-code 98249 Freeland CDP Freeland NMUGA
  17. 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%
  18. Freeland CDP( Census Designated Place) Mean age is 52.1 Growth from 2000 to 2010 was 4.1% annually The CDP is a subset of zip-code 98249 The CDP boundaries differ from the NMUGA, but represent a statistical proxy
  19. FWSD Cumulative Water Connections
  20. 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)
  21. HHSD New sewer connections
  22. 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
  23. 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)
  24. 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%
  25. 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
  26. 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
  27. Environmental Issues

  28. Issues Fecal Coliform / shellfish protection / Freeland Beach Low dissolved oxygen in Holmes Harbor
  29. 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
  30. 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://www.co.thurston.wa.us/health/ehrp/pdf/Nisqually/NisqPollutionSourceReport_12_2004.pdf Note: With over 1,000,000 FC/ml, we are not the “dirtiest” beech
  31. 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
  32. From:Holmes Harbor ShellfishProtection District UpdateIsland County Board of HealthMarch 19, 2012
  33. 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
  34. Low dissolved oxygen Whidbey action area
  35. Holmes Harbor
  36. Proposed Sewer System

  37. 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
  38. 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)
  39. 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
  40. Treatment Membrane bio-reactor (MBR) systems located at: Homes Harbor SD plant Main Street SD plant Other central location(s)
  41. 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
  42. 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
  43. Questions?

    Commissioners: future CAC work?
