Inventory all municipally owned drainage structures including culverts, natural flows and outfalls, swales specifically identified as drainage easements, catch basins and drainage piping. 2. Site visits and recommended remediation of known flooding areas 3. Mapping of inventoried structures using ArcGIS system. 4. Evaluate the condition of the structures. 5. Assess and evaluate the capacity of identified structures. 6. Prepare a capital improvement plan complete with visuals and recommendations for priority of drainage system improvements. Technical Proposals shall be limited to a maximum of ten (10) single-sided pages, including resumes and project descriptions. Any pages submitted beyond the maximum will be discarded and not count toward the proposal evaluation. The total cost to the Town for performing the proposed services shall be indicated, broken down by component and work elements. The Fee Proposal shall be in a separate, sealed envelope, appropriately identified on its face. Task 1 Drainage System Inventory (4 weeks) Consultant shall meet with Town and liaise with Ulster County Department of Environment (MS4 filings) to initiate project and collect mapping and other data on known Town-owned drainage structures.

5 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. Consultant shall provide Town with a mobile collection tablet (ipad or approved equivalent) with rugged field case. 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

6 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.
