Comment on this resource
In this lesson, students will examine the challenges of balancing development and land conversion with the fiscal, technical and political challenges of addressing nutrient loading. They will have the opportunity to examine these issues based on real data and maps from their own watersheds. In Activities 1 and 2 students will compare the nitrogen loads when development occurs inside and outside the growth area, and on differing wastewater treatment options (e.g. central sewer versus septic systems). In Activity 3, students will select best management practices and set implementation targets based on available acres within their tributary basin in order to offset the impacts of new development and meet nitrogen goals. Finally, in Activity 4, students will discuss their recommendations for reducing nitrogen in their tributaries in the face of future growth and discuss the feasibility, cost and political acceptability of these options.
