Task 3 GIS System Mapping (4 weeks) The consultant shall develop a storm drainage system in an Esri standard database. Existing source documentation showing the drainage system shall be used to digitize relevant drainage features: including pipes, catch basins, manholes, outfalls, culverts and stormwater structures. Relevant attribute data such as size, material, year install, and source documentation shall be captured and associated with each feature. Consultant shall configure an Esri Collector application for field investigations of missing features and attributes. Catch basin and drain manhole depth shall be captured in the field and a photograph of each structure investigated shall be taken and associated with each structure in the GIS. The consultant shall host the data and provide access through Esri s ArcGIS Online system for a one-year period. Consultant will provide training for staff in the use of the ArcGIS Online system and the Collector application.

Task 4 Evaluation Condition and Capacity of Structures (4 weeks, simultaneous with GIS) Consultant shall provide a visual condition assessment of all identified Town-owned culverts, drainage manholes and catch basins. Condition should identify specific flaws or deterioration. Consultant shall work with the Town to identify up to 6 specific culverts, drainage structures or drainage swale segments for capacity analysis. The selection of these six drainage system elements will be based upon the Town s 5
flooding observations. The purpose of the analysis will be to prioritize these infrastructure segments for future capital improvements plan, and the analysis shall be conceptual in nature. Capacity analysis will include calculation of estimated stormwater runoff through the stormwater feature for storm return periods of 2, 5, 10, 25 and 50 years, and, proposed resizing of inadequate segments of the selected features, and their estimated construction cost required to carry calculated flows. Task 5 Drainage System Capital Improvements Plan (4 weeks) Consultant shall prepare a 10-year period capital improvements plan that prioritizes needed drainage system improvements, provides a schedule for improvements and an opinion of probable cost. Opinions of probable cost shall consider all construction as well as temporary access, engineering and legal fees.
