Common use of MARINE SHORELINES Clause in Contracts

MARINE SHORELINES. ‌ The marine shorelines in Mason County are located in WRIAs 14a, 15, and 16/14b. Marine shorelines cover about 217 linear miles including the inner shores of inlets, embayments, and estuaries. Mason County nearshore character varies considerably and is composed of numerous geomorphic shore types. Controlling factors within the Mason County marine landscape include climate, wave energy (exposure), sea level, topography, and bathymetry. Other variables influence Mason County marine shores including: net shore-drift of sediment, bluff geology (stratigraphy), tidal regime, and numerous fluvial systems, the largest of which are the Hamma Hamma and Skokomish Rivers. Mason County encompasses marine shorelines in two distinct areas of Puget Sound, including (1) southern Hood Canal (from near Triton Head south), and (2) the southern extent of the Southern Puget Sound sub-basin from between the Pierce County line in northern Case Inlet to the heads of Xxxxxxxxxx, Xxxxxx and Little Skookum Inlets, including Oakland Bay, Xxxxxxxxx Passage, Xxxxx Passage and Xxxxxxxx Island. Several smaller islands are also encompassed within the County including Stretch, Reach, XxXxxxxx, and Hope Islands. Key management issues related to shoreline restoration in the nearshore areas of Mason County include the following: Hood Canal • Low dissolved oxygen concentrations which contribute to adverse effects on fish and other marine organisms; • Water quality degradation related to nutrient loading and high fecal coliform bacteria concentrations in marine waters; • Modifications along the shoreline such as existing bulkheads and hardened armoring; • Highways and transportation corridors (Highway 101) paralleling the shore with impervious surfaces which contribute to stormwater runoff and pollutant loading; • Bridges and causeways creating constrictions at estuary mouths which impair tidal flow; • Development near the shoreline resulting in reductions in forested canopy and habitat; • Cumulative effects on aquatic resources related to construction of new residential docks and piers; and • Removal of trees and clearing native vegetation on private properties for views. South Puget Sound • Water quality degradation related to nutrient loading and high fecal coliform bacteria concentrations in marine waters; • Water quality degradation in Oakland Bay related to dioxins and other contaminants in sediments; • Modifications such as existing bulkheads and hardened armoring; • Highways and transportation corridors (SR 3) resulting in impervious surfaces which contribute to stormwater runoff and pollutant loading; • Bridges and causeways creating constrictions at estuary mouths which impair tidal flow; • Development near the shoreline resulting in reductions in forested canopy and habitat; • Cumulative effects on aquatic resources related to construction of new residential docks and piers; • Removal of trees and clearing native vegetation on private properties for views;
