3 SECTION IV: PROJECT NEED A. This section identifies the local conditions that the community wants to create,enhance, or change. Describe the community's situation,the opportunities it embraces or problems it faces. Describe how your community determines its most important needs. Everett is an incorporated City with a population of 100,000 people. The City of Everett's(City)sewage collection and treatment system provides sewer service to residential, industrial,and commercial customers within four jurisdictions: 1) City of Everett,2)Alderwood Water and Sewer District,3)Silver Lake Water and Sewer District, and 4)City of Mukilteo with combined population of approximately 140,000 people. The City's sewer system plays a vital role in the protection of the public health of the population it serves. In addition,the system protects natural bodies of water,rivers, lakes,streams from pollutants, and minimizes harmful impacts to the natural environment. The purpose of the Comprehensive Sewer Plan is to provide a road map and direction for maintaining,upgrading and expanding the existing system tocontinue to meet the needs of the citizens it serves, and to be able to allow future development while protecting the natural environment. Everett has an aging sewer system with many components approaching 100 years old. In addition to the age of the system, the City's service area has experienced and continues to experience rapid growth,which is adding pressure on the system. The Comprehensive Sewer Plan will identify projects that will address growth, capacity, and physical condition of the system. Currently the City is experiencing basement flooding, sanitary and combined sewer overflows throughout its service area. These basements flooding and overflows pose serious health risks to the served citizens and environmental problems and degradation of quality to the receiving waters where the overflows occur. In addition to identifying the improvement projects,the Plan will also rank these projects with respect to importance and urgency, and will provide a schedule for the construction of these improvements. B. Provide a Scope of Works for the project. Specify major tasks, milestones,participants,area of coordination, and the final product expected from your proposed project(see Guidelines for Public Works Board Standards on Capital Facilities Plans). Be specific in your response. The objective of this study is to develop a detailed comprehensive planning document that can be used by City staff to implement the required improvements to the existing City facilities and results in an agreed upon Capital Improvement Program (CIP).
