  8. Title: Streets, Butte County, California, 2016

    • Line data
    • 2016
    Contributors:

    Summary: The polyline dataset was developed to provide centerline road information for Butte County, California as of 2016. It contains road segments, road names, and geocoded (addressed) road segements for unincorporated areas of Butte County. The file should be used for cartographic purposes and geographic analysis which does not require a high degree of positional accuracy. Note: This is not an adopted layer.BACKGROUND:In late 2004, the existing Butte County road file was adjusted from the old Butte County parcel base, maintained by Butte County Development Services, to align with the Butte County Association of Governments (BCAG) parcel base. The reason being that the BCAG parcel base contains more accurate geometry than the previous base. Also, the BCAG base is being used by the majority of other municipalities in the area.In early 2005, the newly adjusted road file was geocoded to include addressed road segments within unincorporated Butte County. These geocoded (addressed) road segments can be used to place addressed databases using the geocode functions in ArcView and ArcMap. The segments were addressed using the existing Butte County address point file and the existing BCAG address point file. The Butte County address point was determined to be approx 80-85% accurate for the rural areas of the county, at that time. The BCAG address point file was determined to be approx 95-97% accurate for the incorporated areas of the county, at that time. These approx accuracies refer to attributes and parcel level position, not positional in terms of being on the actual structures.As of August 2005, an effort is currently in process to realign the road segments from the parcel base to the aerial photo's. It is fairly well known that certain areas of the county, mostly rural, have parcel boundaries and easements which do not align precisely with the aerial photo base. The reason being that some assessor parcel pages are fairly outdated and were not originally drawn, by the Assessor's Office, using survey data. In order to increase the positional accuracy for future projects and analysis, road segments which do not match the aerial photo base will be realigned. A seperate layer will be available, upon request, which contains segments that follow the parcel file. This process is expected to take several months to complete.The following fields were added in October 2005: jurisdict, ramp, and direct. 'Jurisdict' is populated with road jurisdiction attributes obtained from Butte County Public Works road name list file. Not all roads contained attributes, so a file of those roads were returned to public works. 'Ramp' and 'Direct' fields were added to signify off and on ramps for state highways. The direction marks which way the traffic is exiting or entering the highway. Note: The jurisdiction is for general reference purposes only and may not actually determine jurisdiction.The following fields were added in December 2005: road_no, fr_mile, to_mile, and length. These fields will be used for routing and general reference purposes for by the Butte County Public Works department. See process step 2 for more info.The following field was added in March 2006: major. Field was requested by LAFCO analyst for cartographic purposes. See process step 3 for more info.

  20. Title: Lake Michigan Bluff Crest Recession, Wisconsin 1956 - 2015

    • Point data
    • 2015
    Contributors:

    Summary: Lake Michigan coastal bluff recession information is provided for Kenosha, Racine, Milwaukee, and Ozaukee Counties (collectively called “southeastern Wisconsin”). Data shown represents the distance the bluff has receded, or moved landward, over two analysis periods: a long-term period from 1956 to 2015 and a short-term period from 1995 to 2015. Recession information is provided for the bluff crest defined as the location where the relatively flatter upland meets the steeper bluff face.The coastal recession information was produced as a part of ongoing studies at the University of Wisconsin-Madison Coastal Sustainability Laboratory. This data has been made public through collaborations of the University of Wisconsin-Madison, the Wisconsin Coastal Management Program, University of Wisconsin Sea Grant, and the Association of State Floodplain Managers. The data presented here should be considered preliminary and may not reflect current conditions along the coast.Each data point represents an average of recession measurements along a 300-foot section of coast and does not represent any specific property or municipal boundaries. Note that a positive recession value represents a landward movement of the feature and a negative recession value represents a lakeward movement of the feature, also known as accretion.The recession information can provide useful insights into the historic migration of the southeastern Wisconsin coast. It should be noted that the recession distances provided here represent how the bluffs have responded to historic environmental conditions and human actions over a specific time period in the past (1956-2015 and 1995-2015). There is always uncertainty in how bluff recession will respond to future conditions. Bluff recession can also be sporadic. For example, a bluff crest that had remained unchanged for decades can recede many feet almost instantly due to a bluff collapse. Human actions may also change the evolution of the coast. For example, a bluff that may have been heavily eroded historically may have been recently stabilized or had shore protection added such that recession could be expected to decrease compared to historic rates.
