Napa Valley woodland preservation rejected
A county measure to preserve woodland and watershed areas in California's Napa Valley wine region has been narrowly voted down. The measure would have restricted the expansion of vineyards, and wine industry advocates now say they're ready to work with environmentalists to achieve some of the same ends.

Erosion/Sediment Control
Why are Vt.'s cleanest lakes deteriorating?
Small improvements are now evident in Vermont's most polluted lakes, but water quality in the cleanest lakes is deteriorating. The situation is puzzling, but one possible explanation is the natural occurrence of eutrophication in lakes as they age, a process that may be accelerated by human activity.

High Lake Erie waters pose erosion threat
Erosion is a growing concern along Lake Erie shorelines as water levels persist near record highs. Part of the problem, say Ohio state officials, is infrastructure put in place decades ago that is now nearing the end of its service life.

Ohio city seeks savings in sewer cleanup
Alternative designs could knock $75 million off the $1.2 billion cost of an Akron, Ohio, sewer project. The savings are contained in amendments to the original deal with state and federal authorities and still must be approved by them as part of the plan to bring the system in line with the Clean Water Act and prevent sewage overflows into the Cuyahoga River by 2028.

How LID affects groundwater
Low impact development can help curb the effects of development on groundwater, but the overall effect remains little understood. A case study in China pairing a Storm Water Management Model and Finite Element Subsurface FLOW system model confirms the taming of runoff but also reveals that LID can raise the risk of groundwater flooding during wet seasons in some areas.
