Exhibit A Scope of Services Steve's Plumbing Residential Plumbing, Sewer,and Drainage Investigation Services This work scope to provide site inspection services for residential properties affected by recent basement flooding and other impacts associated with the surcharge of the public sewer system. This work scope is to provide site investigative services to characterize existing site conditions relating to site plumbing, sewer, and drainage; determine plumbing, sewer, and drainage deficiencies that could contribute to flooding and sewer surcharge impacts, and recommend private site improvements to prevent impacts from potential future sewer surcharge events. Task 1 Property Investigations and Reports Complete up to 60 individual property site investigations and reports. Each investigation will provide the • following: a review of site drainage and how runoff may contribute to basement flooding;how roofs drain and if connected to side sewers; side sewer condition inspection;how side sewers are connected to site plumbing and best determine all side sewer connections; and status of internal plumbing including all lines,connections,and fixtures potentially influenced during a sewer surcharge event. Contractor will use as necessary survey equipment, side sewer cameras, internal plumbing pipe cameras(to a minimum pipe diameter of 1 1/4"), sondes, and other plumbing and drainage equipment as necessary. Property owners or their representative will be scheduled by the city to be present or available and onsite during the inspections. The site report will present findings and recommendations, and must include at a minimum the following: •Recommended corrections to the private sewer systems to prevent or eliminate drainage and sewer flows from entering basements during rain events, sewer surcharge events, etc. •Site drainage recommendations—what possible measures should be implemented including grading or drainage features to prevent or eliminate site drainage from entering basements and side sewers; •Roof drain discharge—what practicable alternatives are available rather than being connected to the side sewer and also to not contribute to basement flooding; -Internal plumbing—corrective plumbing measures including rerouting pipes,replacing fixtures, new protective devices, or removing fixtures; and 'Side sewer improvements—their condition, connections, and slope improvements necessary, and the appropriateness of a backwater valve for the residence and if so,the recommended location for the valve. The site report will include:photographs of the property and photos of issues identified in the inspection; as-builds of the property's underground side sewer and all known connections—pipe locations will be based on sonde detections and measurements from known reference points. A summary report will be prepared for each property. The report format will be consistent as shown in Exhibit D. Reports must be submitted electronically and in hard copy within 5 business days of plumbing inspection scope ins 090913.docx 1 9/11/2013
