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)
