Implications
1.3% average annual increase in development regulation
Growth management remains an important and vital opportunity to influence water management
![Page 7: #12 - Comp Plan - Trends & Implications](https://reader034.fdocuments.us/reader034/viewer/2022052601/559534bb1a28ab905f8b47b4/html5/thumbnails/7.jpg)
Expectations for Management
Steady increase in demand for recreation and wildlife oriented uses
![Page 8: #12 - Comp Plan - Trends & Implications](https://reader034.fdocuments.us/reader034/viewer/2022052601/559534bb1a28ab905f8b47b4/html5/thumbnails/8.jpg)
Land Use
Current PlanProvides general statisticsPopulation forecasts were off -24%Describes general demands for water & related
resources (No numbers)
![Page 9: #12 - Comp Plan - Trends & Implications](https://reader034.fdocuments.us/reader034/viewer/2022052601/559534bb1a28ab905f8b47b4/html5/thumbnails/9.jpg)
Trends & Projected Changes
![Page 10: #12 - Comp Plan - Trends & Implications](https://reader034.fdocuments.us/reader034/viewer/2022052601/559534bb1a28ab905f8b47b4/html5/thumbnails/10.jpg)
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
![Page 11: #12 - Comp Plan - Trends & Implications](https://reader034.fdocuments.us/reader034/viewer/2022052601/559534bb1a28ab905f8b47b4/html5/thumbnails/11.jpg)
Expectations for Management
Turbidity and TSS problems occurring elsewhere in watershed
Gradual increases in demand across programs
![Page 12: #12 - Comp Plan - Trends & Implications](https://reader034.fdocuments.us/reader034/viewer/2022052601/559534bb1a28ab905f8b47b4/html5/thumbnails/12.jpg)
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

Trends
17% decrease in drainage dependent/ sensitive lands
642 acres
![Page 15: #12 - Comp Plan - Trends & Implications](https://reader034.fdocuments.us/reader034/viewer/2022052601/559534bb1a28ab905f8b47b4/html5/thumbnails/15.jpg)
Implications from Changes in Demand for Drainage
Overall Demand for drainage decreases
![Page 16: #12 - Comp Plan - Trends & Implications](https://reader034.fdocuments.us/reader034/viewer/2022052601/559534bb1a28ab905f8b47b4/html5/thumbnails/16.jpg)
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
![Page 17: #12 - Comp Plan - Trends & Implications](https://reader034.fdocuments.us/reader034/viewer/2022052601/559534bb1a28ab905f8b47b4/html5/thumbnails/17.jpg)
TransportationCurrent Plan
General description of road system

Trends
Traffic volumes expected to increase
![Page 19: #12 - Comp Plan - Trends & Implications](https://reader034.fdocuments.us/reader034/viewer/2022052601/559534bb1a28ab905f8b47b4/html5/thumbnails/19.jpg)
Implications
More aggressive winter maintenance (salt & sand = Chlorides & TSS)
![Page 20: #12 - Comp Plan - Trends & Implications](https://reader034.fdocuments.us/reader034/viewer/2022052601/559534bb1a28ab905f8b47b4/html5/thumbnails/20.jpg)
Expectations
Winter maintenance (Use of salt)
