Description: Coastal armoring structures are built extensively along California’s 1,100-mile coastline by private landowners, local, state, or federal governments to protect coastal development threatened by erosion. A pilot study for Santa Cruz County captured all of the coastal armoring structures using orthophoto/oblique high-resolution imagery and the California Coastal Commission (CCC) Permit Tracking System (PTS). The geodatabase will assist coastal managers and planners in identifying where past, present, and future development projects are located, identify the resources potentially impacted by a project, and perform analyses on the cumulative impacts of other nearby projects. The dataset also allows a user to analyze spatial relationships among coastal armoring practices, answer important coastal management questions related to coastal armoring, and manage information more effectively.

Description: This dataset is a compilation of the UCSC Sand Retention Structures, MC Barriers, and USACE Coastal Structures. UCSC Sand Retention Structures originate from a catalog of 211 man-made structures along California's open-ocean shoreline. The original database includes the physical attributes of each structure, as well as information pertaining to its coastal setting and history. A determination of the total sandy beach area retained by each structure was based on fillets or salients that are visible in aerial imagery and on the pre-post construction shoreline positions in the proximity of each structure.The lifespans of coastal stabilization, beach restoration and beach nourishment projects may be extended by the presence of man-made structures that act as barriers to littoral drift. An underutilized and cost-effective resource for understanding how these artificial barriers perform is the record of existing structures within California.USACE Coastal Structures were digitized as part of the nation-wide Navigation and Coastal Databank Program, which was concurrently operating in both San Francisco and Los Angeles USACE Districts between 2009 and 2011. This feature class is a compilation of geographic data digitized from various sources, including Coastal Structures Program Project Management Plans and the Enterprise Coastal Inventory Database. This dataset only includes Corps maintained jetties, breakwaters, groins and training walls. MC Barriers were obtained from the Coastal Regional Sediment Management Information System, and was last updated by John Carotta for CSMW in July, 2007. This dataset contained both man-made and natural barriers, mostly headlands. Due to poor attribution and metadata recording keeping, little of the attributes were preserved, and it is unknown where this dataset originated.

Description: The Navigation Data Center maintains a database (Master Docks Plus) of over 40,000 port-and-waterway facilities and other navigation points of interest. The data describe the physical and inter-modal (infrastructure) characteristics of the coastal, Great Lakes, and inland ports of the United States. The data include, but are not limited to location (latitude/longitude, waterway, mile, and bank); operations (name, owner, operator, purpose, handling equipment, rates, and details of open-and-covered storage facilities); type and dimension of construction (length of berthing space for vessels and/or barges, depth, apron width, deck elevation, and details of rail-and-highway access); and utilities available (water, electricity, and fire protection).The port facilities database contains a national inventory which delineates the Nation's principal coastal, Great Lakes and inland port and waterway terminal and transfer facilities. The information is used to analyze the use and improvement of existing terminals and the planning and development of new ones. Primary users are Federal, state and municipal agencies; and port and waterway development authorities.Dataset was derived from the Master Docks Plus Public Extract database, which is a Microsoft Access database that contains a complete extract of the Navigation Data Center’s dock database with all data that may be released to the public. Database was downloaded on February 3, 2012, the last update of the Master Docks Plus Public Extract was 1/25/2012 1:31:15 PM.

Description: The Monterey Interceptor between Seaside Pump Station and Monterey Beach Resort is buried in the dunes, approximately 100 to 175 feet from the dune bluff. Between Monterey Beach Resort and Tide Avenue the pipeline is not under imminent threat of erosion damage (PWA and Griggs, 2004). However, the pipeline could be vulnerable during a large storm event towards the end of the 50-year planning horizon. From Tide Avenue to Monterey Pump Station, the pipeline is located in the dunes a minimum of 115 feet from the shoreline. Between Monterey Pump Station and Wharf II, the Monterey Interceptor was originally buried beneath the back beach, but due to erosion is now at mid-beach.Based on approximate future erosion rates of between 1.5 and 3.0 ft/year, the shoreline between Seaside Pump Station and Monterey Beach Resort would be expected to erode 75-150 feet over the next 50 years, and parts of the pipeline between these two locations may be compromised over the next 40 years. The erosion could uncover the pipe and/or manholes and make them vulnerable to damage. Hence, the Monterey Interceptor between Seaside Pump Station and Monterey Beach Resort is a facility at high risk of erosion (PWA and Griggs, 2004). Between Monterey Beach Resort and Monterey Pump Station, the future erosion rate is estimated at approximately 1.5 ft/year, and therefore the pipeline would be at low risk of chronic erosion over the next 50 years. However, given the accuracy of the base map (+/- 16 feet) used to define the position of the pipeline in the dunes here (PWA and Griggs, 2004), it is designated as a moderate risk facility with the potential for storm damage towards the end of the 50-year planning horizon. Between Monterey Pump Station and Wharf II the shoreline is estimated to erode at an average future rate of approximately 1.0 ft/year and the beach has been observed to scour during storms (Dingler and Reiss, 2002). Manhole covers are now sometimes exposed at low tide during the winter and are vulnerable to damage. At this location, the Monterey Interceptor pipeline is under imminent threat of erosion damage and is at high risk of erosion (PWA and Griggs, 2004).The Monterey Interceptor carries all of the raw (untreated) wastewater from the cities of Pacific Grove and Monterey. This flow is pumped through Monterey and Seaside Pump Stations to the MRWPCA Regional Treatment Plant. The pipeline is a vital facility that needs to remain fully operational indefinitely, and the consequences of erosion would be significant economic, environmental, and human health impacts. A breach to this facility would have adverse environmental impacts to the dunes and beaches, and water quality impacts within the MBNMS. The exposure of the pipeline would be a threat to marine resources if erosion caused a spill to occur. The Monterey Interceptor between Seaside Pump Station and Wharf II is therefore a high consequence facility. The shapefile showing the occurence of the pipline and the segments according to risk was prepared by PWA for the Southern Monterey Bay Coastal Regional Sediment Management Plan (AMBAG, 2008)

Description: This dataset is an updated version of the shapefile created by Jennifer Dare at the California Coastal Commission in 2005. The original version of this shapefile was created by comparing oblique aerial imagery on the California Coastal Records website (www.californiacoastline.org) and vertical imagery to locate shore protection structures. A polyline representing the alongshore length of each structure was digitized by tracing an existing shoreline shapefile.The version created by Elena Vandebroek (ESA PWA) in 2011 changed the original version in the following ways: - Study area was focused to San Francisco County and part of San Mateo County. - Armoring was moved/added to a more accurate location in space, using NAIP aerial imagery from 2010. The original armor data set projected all armoring along a single shoreline. - The new armor dataset reflects removals, additions, or changes to the armoring in the study area since the 2005 armor dataset by Jennifer Dare. - Linear and polygon features were separated into two separate shapefiles. Revetments are considered polygon features while seawalls, mid bluff walls, upper bluff walls, jute, and piles are considered linear features. This allows for approximate volume/area and length calculations of revetments and linear features, respectively. Dataset was submitted to CSMW as part of the San Francisco Littoral Cell Coastal Regional Sediment amanagement Plan (2012).
