  3. 3. Review Of Current Chapter <ul><li>Focuses on projected growth in </li></ul>Housing Population 14% 24% 41% Change 168,300 148,000 119,783 Total 2010 2000 1990 19% 32% 58% Change 60,500 50,750 38,553 Total 2010 2000 1990

  5. 5. Trends: Pct Growth in Decade 13% 22% Total 11% 27% Ham Lake -1% 7% Coon Rapids 23% 6% Columbus 29% 39% Blaine 12% 41% Andover 2020 2010
  6. 6. Implications <ul><li>1.3% average annual increase in development regulation </li></ul><ul><li>Growth management remains an important and vital opportunity to influence water management </li></ul>
  7. 7. Expectations for Management <ul><li>Steady increase in demand for recreation and wildlife oriented uses </li></ul>
  8. 8. Land Use <ul><li>Current Plan </li></ul><ul><ul><li>Provides general statistics </li></ul></ul><ul><ul><li>Population forecasts were off -24% </li></ul></ul><ul><ul><li>Describes general demands for water & related resources (No numbers) </li></ul></ul>
  9. 9. Trends & Projected Changes
  10. 10. Implications <ul><li>7,500 acre decrease in agricultural & vacant land </li></ul><ul><li>45 to 50 acres per year average 2010 – 2020 </li></ul><ul><li>110 to 130 permit applications per year </li></ul><ul><li>7,800 acre increase in impervious surface mostly in headwaters </li></ul>
  11. 11. Expectations for Management <ul><li>Turbidity and TSS problems occurring elsewhere in watershed </li></ul><ul><li>Gradual increases in demand across programs </li></ul>
  12. 12. Drainage <ul><li>Current Plan </li></ul><ul><ul><li>Describes nature of drainage demand </li></ul></ul><ul><ul><li>Describes drainage system as ‘Generally Acceptable Condition’ </li></ul></ul><ul><ul><li>Differentiated ditches based on their role (Ag, Stormwater, Collector, Trunk) </li></ul></ul><ul><ul><li>Set standards for each role </li></ul></ul><ul><ul><ul><li>Condition </li></ul></ul></ul><ul><ul><ul><li>Maintenance </li></ul></ul></ul>
  13. 14. Trends <ul><li>17% decrease in drainage dependent/ sensitive lands </li></ul><ul><li>642 acres </li></ul>
  14. 15. Implications from Changes in Demand for Drainage <ul><li>Overall Demand for drainage decreases </li></ul>
  15. 16. Expectations for Drainage Management <ul><li>Changes in maintenance standards in much of the watershed </li></ul><ul><li>Need to inspect ‘critical reaches’ to ensure drainage on remaining lands (annually?) </li></ul><ul><li>Use of public ditches for water storage likely to increase in short term </li></ul>
  16. 17. Transportation <ul><li>Current Plan </li></ul><ul><li>General description of road system </li></ul>
  17. 18. Trends <ul><li>Traffic volumes expected to increase </li></ul>
  18. 19. Implications <ul><li>More aggressive winter maintenance (salt & sand = Chlorides & TSS) </li></ul>
  19. 20. Expectations <ul><li>Winter maintenance (Use of salt) </li></ul>
