434 - Tier II Complete Hydrologic and Hydraulic Design, 555 - NPDES Stormwater Program - BMP Retrofit Site Selection and Design
1.  Draft and final peer state LID research findings (Part I)
2.  Draft and final revisions to the content of the 2014 edition of the BMP Toolbox.  Content reviews may include updates to general descriptions, technical specifications, photographs, illustrations, etc. (Part II)
3.  Draft and final new Toolbox manual chapters (Part II)
4.  Draft and final training materials (specifics TBD) along with an in-person or virtual training session for Hydraulics Unit staff (Part III)
Part I:  Conduct research on peer states’ use of LID guidelines and regulations.  For this project ‘peer states’ will be defined as other state DOTs, other state regulatory agencies (including NCDEQ), and select federal agencies such as the USEPA, FHWA, and the US Army Corps of Engineers.  The research will identify the various ways LID is defined with particular distinction being made between ‘design philosophy’ versus ‘stormwater treatment standard’.  The research will summarize any LID-related regulatory requirements applicable to state DOTs, as well as identify best management practices considered as LID practices appropriate for the linear environment.  The research findings will be documented in a report.

Part II:  The Department’s last update to the BMP Toolbox was in 2014, thus initial tasks will involve reviewing the existing BMP Toolbox chapters and recommending any appropriate updates to the current content.  Over the past few years, the Hydraulics Unit has been planning its next update to the Toolbox and has already identified additional practices which may achieve LID benefits including promoting infiltration or otherwise extending the runoff hydrograph.  Informed by the Part I research and the Unit's planned updates, additional tasks involve identifying BMPs not currently described in the 2014 addition of the Toolbox and prepare new Toolbox manual chapters descibing these BMPs.  It is anticipated that the new chapters will have a similar 'look and feel', as well as content type as the current Toolbox manual.  

Part III:  Prepare training materials describing the updated BMP Toolbox manual.  The training may involve in-person or virtual training targetting Hydraulics Unit staff.  Additional materials may involve hardcopy and/or recorded video based training which could be posted to the Department's Learning Management System in the form of one or more courses.

434 - Tier II Complete Hydrologic and Hydraulic Design
Specific deliverables will be defined by the project plan.
Specific tasks will be assigned by the Hydraulics Unit project manager.  Example tasks might include:
Task 1:  Review available recommendations from the IPD Team, the Hydraulics Unit Data Management Plan (under development), and the Hydraulics Unit Strategic Plan (under development).  Review list of comments and issues in the 2016 Guidelines discussion log and make recommendations regarding any inadquacies or corrections which need to be addressed.  Consult with the State Hydraulics Engineer and select unit staff to identify the goals and objectives for the project.  Compile these goals and objectives into a written project plan which defines specific deliverables, PEF and Unit team members for a given deliverable, and associated schedules.

Task 2:  Execute the project plan which is expected to be phased to coincide with known near term objectives and additional objectives which emerge from recommendations being prepared by the various initiatives under development and mentioned above.  These objectives will likely include an assessment of the Unit's various policies, procedures, guidelines, forms, and checklists to determine its continued relevance and purpose into the future.  Relevant items will be updated as appropriate, and if necessary, be transformed into a format to most effectively deliver the content to the end user.  Such formats may include web pages, geodatabases, MicroStation files, electronic forms of various formats, etc.

Task 3: Provide training for Hydraulics staff and end users to update on changes made to guidance and how best to utilize with IPD workflows.  Format of training may be in brief online video modules, classroom setting, printed materials, or other means as deemed appropriate.

Task 4:  Provide GIS support to NCDOT's Project Atlas Team related to the Unit's geospatial data.
