Sitka Sedge State Natural Area Hydrology Modeling

Oregon Parks and Recreation Department (OPRD) is developing a scope of work to engage in a comprehensive hydrological  analysis of Sitka Sedge State Natural Area, building off digital elevation model information and preliminary groundwater monitoring collected in 2015-2016. This information will inform future decisions for habitat restoration on OPRD property, especially regarding potential effects on groundwater from increased tidal exchange in the estuary.

OPRD held an advisory committee review of the scope of work for this hydrology study on September 6, 2016. The intent of this review was to shape the draft scope of work to make sure that it considers all relevant concerns in regards to potential restoration. Hydrological consultants tasked with this analysis have revised the draft scope in February 2017 based on comments received at that meeting and sent to OPRD in September and October of 2016.

DRAFT Sitka Sedge Hydrology Scope of Work (8/2016)

FINAL Sitka Sedge Hydrology Scope of Work (Revised 2/2017 based on comments received 9/10 2016)

Sept. 6, 2016 Meeting Presentation

Once data collection is completed a report will be made available and reviewed with the public. At this time, OPRD anticipates this study could take up to two years, at which point the neighborhood and advisory committee will be engaged in continued conversations about potential restoration options – with comprehensive data as a reference.
