Frequently Asked Questions

  1. What browser should I use for best performance?
    Google Chrome is recommended. 

  2. How accurate is the registry at predicting opportunity sites?
    The registry is purely a targeting tool, no guarantees are made about its accuracy; choosing a registry suggestion as a mitigation site does not ensure approval. 

  3. What information is needed to use the registry?
    None.  Although having either a geographic location or type of mitigation in mind would be helpful.

  4. Who is involved?
    The Baltimore District Army Corps of Engineers, Headquarters Army Corps of Engineers, US Environmental Protection Agency Region 3, US Fish and Wildlife Service, Federal Highway Administration, Maryland State Highway Administration, Maryland Transportation Association, National Marine Fisheries Service, Maryland Department of Natural Resources, Maryland Department of the Environment, Charles and Prince George’s Counties, and Nongovernmental organizations, i.e. the Conservation Fund

  5. Who can utilize this tool and for what purposes?
    Anyone can use the WRR interactive website.  It is used as a targeting tool for mitigation sites of a specific ecological opportunities or in a specific county or  watershed.

  6. What ecological opportunities can be identified using the registry?
    Upland preservation, upland restoration, wetland preservation, wetland restoration, riparian preservation, riparian restoration, natural stormwater infrastructure preservation, and compromised stormwater infrastructure restoration are the 8 different models available within the registry.

  7. What makes the WRR different from other programs?
    It integrates multiple programs from the CWA, and moves mitigation efforts away from a stovepipe approach, towards a comprehensive watershed view.  There was also collaboration between regulatory and non-regulatory agencies.

  8. Can I use it to pinpoint areas that impact my special interest?
    Yes, by using the Find Opportunities tool you can select a particular type of mitigation.  Also, by turning data layers on and off in the left hand menu you can determine where your special interest is located within a watershed and perform watershed appropriate mitigation in the surrounding area.

  9. Is it possible to incorporate information not presented in the registry? If so, how can this be done?
    It is not possible to add extraneous data layers to the registry.  However, if there is existing data you would like to include in your search you can select sites and then compare your maps manually.  It is also possible to consume the site in ArcGIS using the GIS Servers option under “Add Data”.

  10. How can my organization (or other organizations) contribute new information to the registry?
    Once sites for field verification have been identified and data has been collected relating to the provided data sheets the data can then be re-entered into the WRR using the Site Assessment upload tool found within the WRR application.

  11. Where can willing owners enter mitigation sites?
    See answer for question 10.

  12. What can be done if the registry is found to be inaccurate after conducting a ground-truthing?
    See answer for question 10.

  13. How was the registry developed?  Is it available for consumption in GIS software?
    The WRR was developed through the GIS Model Builder and is accessible to those with the GIS software.  Most of the raw data used to develop the registry is available through public download sites which are listed on the GIS layers page.

  14. Why can’t I change the order of the layers on the map?
    The Registry is a static web application that does not allow alteration on the part of the user.

  15. Who can be contacted for technical questions and support?
    Michael Herzberger
    Maryland Environmental Service

  16. Why can’t I find my address?
    The registry covers Maryland  only right now; if you are outside the state your address will not appear.  If you are in Maryland make sure you have entered your zip code correctly and only entered your street number and name, not your town, into the first line.

  17. Can it be expanded to cover my state/county/watershed/etc.?
    At the moment the WRR is in Maryland.  There is the potential to replicate the model in any area where the needed data exists.

  18. Why should I use the WRR if I am still going to hire a consultant?
    The WRR will simplify the work for the consultant.  Instead of searching blind they can use the registry to select a few sites that show potential, then ground truth them to determine which is the best for your specific needs.

  19. How does the transaction cost go down for implementing these tools and approaches?
    The use of the WRR will save time and money from a project delivery standpoint to further efforts in the protection of valuable resources within Maryland.  For example, ensuring that MD SHA is providing mitigation and stewardship projects that are consistent with watershed needs.

  20. After finding opportunity sites of my interest, what is the next step to take before implementing any information into my plans?
    Compare the data to the aerial photo, if it seems to match, the next step is ground-truthing.

  21. How can the information from the registry be useful in planning a land use design?
    The WRR could help to identify areas that should be avoided developmentally.  Or conversely, areas that do not qualify for any mitigation opportunities would also be areas where development would be plausible.

  22. How could the WRR inform me relating to work I am presently conducting?
    The WRR could provide additional resource information from an avoidance and minimization perspective during the design process, and can help inform decision making when it comes to appropriate stormwater management controls/BMPs and mitigation/stewardship for wetlands, streams, stormwater and uplands.

  23. Can permits be established through the registry?
    In the Phase I Mitigation Plan submittal, when an applicant proposes a mitigation site, they should discuss how it fits into the WRR.  They could also do this during the application for the impacts - include a discussion of the alternatives considered for the alignment, impacts, etc. using the WRR.

  24. Since all of the government agencies helped to put the WRR together, does that mean I don’t need approval if I pick my mitigation site from the choices on the WRR?
    You still need approval for your site.  The WRR is just a targeting tool, selecting a site it finds for your mitigation does not guarantee approval.

  25. How could the WRR be used by non-governmental agencies?
    It could also be used by private developers to guide their land use decisions and help target mitigation needs as well as being used by Land Trust and wetland bankers to target areas for purchasing and preserving.

  26. How can the WRR be used on a local level?
    The WRR could be used at the local level to guide master planning efforts.  It can be utilized by local DOTs and agencies in very similar fashion that SHA is anticipating to use for protection and mitigation opportunity identifications.  Other organizations regulating and intending to support the Chesapeake Bay TMDL may also utilize this tool. 

  27. Why are certain layers grayed out on the site?
    Certain layers are scale dependant; this means that they are only viewable at specific scale ranges.  If you have grayed out layers try zooming in or out to determine at what point they become available.

  28. Was the WRR verified?
    Yes, it went through a desktop review before being field tested.  To see complete verification procedures click here.
