Welcome to the Collaborative Watershed Mapping Tool V2.0
This tool was created for the Lancaster Clean Water Partners by Chesapeake Conservancy with guidance from the Watershed Action Team. The data layers in the tool provide spatial
information and landscape context to support planning efforts of restoration and conservation professionals in Lancaster County, Pennsylvania. To protect the privacy of the
Lancaster County community, parcel information -- including insight on potential restoration projects shared during the fall 2020 Lancaster Clean Water Partners online workshops--
is only currently accessible through a different mapping tool. Contact the Lancaster Clean Water Partners to access the map with parcel information:
These instructions can be referenced at any time by clicking the 'How To?' button in the top right-hand corner of the page.
To go back to the initial map view and visible layers at any time, click the 'Reset Map' button.
Data sources and descriptions are available
here for reference while using this tool. These can also be accessed by clicking on the 'Information' button next to data layers.
Click on the tabs within the mapping tool to explore a variety of data layers:
Prioritization: This tab shows priority watersheds for restoration at the catchment scale which were then aggregated to the HUC12 watershed scale,
and also aggregated to the scale of large watersheds that local groups reference for planning purposes. The factors that went into the priority level are each
included as their own data layer listed below the priority datasets.
Water Quality: This tab includes data layers with information on water quality including index of biological integrity (IBI) and water quality monitoring data.
Policy: This tab includes data layers from federal, state, and local agencies related to water quality, designated uses, flood risk, land use, environmental justice, and urban development.
Implementation: This tab shows data layers relevant to implementation at the local scale including existing planning efforts, high-resolution hydrology, and best management practice (BMP) opportunities.
To find out whether an address is within a Priority Catchment (in the Prioritization tab),
simply ensure that layer is checked "on" in the layer list, search for the address in the search bar at the top left hand corner of the map, and click on the catchment on the map. This will display a popup box
where you can find the catchment Tier (Tier 1 is highest priority), and catchment score.
To view data layers of interest, click on the radio buttons or checkboxes next to the layer name. Click the grey drop down arrow next to a group layer to expand and see individual layers.
To view sublayers, the group layer and sublayer must both be checked. Some layers may be greyed out, simply zoom in and these layers will appear for viewing.
Click on the map to see a popup with more detailed information on the visible layers.
If multiple layers are visible, use the arrow buttons at the bottom right of the popup window to navigate between different layers' popup windows.
The Lancaster Clean Water Partners brings together a diverse group of partner organizations – local leaders in business, municipal public service, higher education,
conservation planning, and non-profit management – with a shared vision of clean and clear water in Lancaster County by 2040. Its shared mission is to rapidly
accelerate and expand the ability of the partner organizations to restore and sustain healthy Lancaster County waterways.
The Partners envision a publicly accessible tool that provides a variety of relevant information about Lancaster County watersheds to support smart watershed restoration
decision making. This tool was created through the collaborative efforts of research organizations, local and state entities, nonprofits and restoration professionals
involved with the Lancaster Clean Water Partners.
Your continued feedback on this tool is essential to ensure that it is serving the Lancaster County conservation and restoration community.
We encourage you to join the Watershed Action Team to help shape the data-driven decision-making that will support our work together.
Information about the next meeting can be found here.
