Jeff Tirschman, PMP

2 Presentation Overview
Background Restoration Strategies GIS Database GIS Applications Questions

3 Chesapeake Bay Pollution Diet TMDL Implementation
TMDL (WLA) Reduction Load Pollutant Level Pollutant Healthy Loads 0 lbs/yr Baseline Load (Current Condition) Impairment Total Maximum Daily Load Establish Current Conditions (Baseline) Define Impairment Reduction in Pollution Planned Projected Tracked

4 Chesapeake Bay TMDL & Local TMDLs
Bay TMDL Addresses Impairments in the Bay & its Tidal Segments Locals TMDLs Address Impairments in 8-Digit Watersheds

5 Restoration Goals 20% Impervious Area Restoration Bay TMDL Compliance
Nitrogen Phosphorus Sediment Local TMDL Compliance Various requirements

6 Water Quality Improvement Strategies
Restoration Strategies Land Use Changes Tree plantings Impervious area removal Impervious area to forest

7 Water Quality Improvement Strategies
Restoration Strategies Structural Stormwater Wet Ponds Bioswales Infiltration practices Grass swales Retrofits

8 Water Quality Improvement Strategies
Restoration Strategies Load Reduction Stream restoration Outfall stabilization Inlet cleaning Street sweeping

9 GIS Database Centralized Database Repository Modeled Geodatabase
Features representing project / asset locations Attributes describing assets Aligned to MDE Reporting Requirements

10 Comprehensive GIS Database Design

11 Data Storage & Management
Features Site selection features BMPs / assets Attributes Location Dates Credits Impervious area treatment Design criteria Files

12 Data Migration & Integration
Various Formats MS Excel spreadsheets MS Access databases Shapefiles Maximo output reports Site selection reports Field maps Project summary sheets Determine System of Record Opportunities Challenges

13 Information Architecture / Accessibility
Database Integration Web Services Map Services Versioned Environment Security Accessibility

14 Foundation for Project Lifecycle
Planning / Watershed Improvement Plan Development Site Selection Design Construction Maintenance Inspection Reporting Impervious Accounting

15 GIS Data Collection & Tracking Tools
Site Selection Desktop Assessment GIS screening Ranked sites based on various parameters Resources Land use / land cover Contours Site size SHA ROW Utilities

16 GIS Data Collection & Tracking Tools

17 GIS Applications eGIS Bay Restoration Editor
