Implications
1.3% average annual increase in development regulation
Growth management remains an important and vital opportunity to influence water management
Expectations for Management
Steady increase in demand for recreation and wildlife oriented uses
Land Use
Current PlanProvides general statisticsPopulation forecasts were off -24%Describes general demands for water & related
resources (No numbers)
Trends & Projected Changes
Implications
7,500 acre decrease in agricultural & vacant land
45 to 50 acres per year average 2010 – 2020
110 to 130 permit applications per year
7,800 acre increase in impervious surface mostly in headwaters
Expectations for Management
Turbidity and TSS problems occurring elsewhere in watershed
Gradual increases in demand across programs
DrainageCurrent Plan
Describes nature of drainage demandDescribes drainage system as ‘Generally
Acceptable Condition’Differentiated ditches based on their role
(Ag, Stormwater, Collector, Trunk)Set standards for each role
ConditionMaintenance
Trends
17% decrease in drainage dependent/ sensitive lands
642 acres
Implications from Changes in Demand for Drainage
Overall Demand for drainage decreases
Expectations for Drainage ManagementChanges in maintenance standards in much
of the watershed
Need to inspect ‘critical reaches’ to ensure drainage on remaining lands (annually?)
Use of public ditches for water storage likely to increase in short term
TransportationCurrent Plan
General description of road system
Trends
Traffic volumes expected to increase
Implications
More aggressive winter maintenance (salt & sand = Chlorides & TSS)
Expectations
Winter maintenance (Use of salt)
