Projects in Design

When a project has been approved in the budget by the City Council, it moves from the Capital Improvement Plan (CIP) list into the active Design phase.  The Design phase is an exploratory process where City staff identifies key elements of the project, researches information needed to implement the project, hires and Engineering firm to lead the design team and solicits public input.

The design of a project is a very important first step to identify construction elements to promote the timely delivery of the project with as little impact to neighboring properties as possible.

A Project Manager (PM) is assigned to each project on the CIP list.  The PM is the point of contact for the public and is responsible for guiding the engineering firm through the design process until a complete set of plans are approved by the City.

As the plans are developed, they go through phases of completion.  These phases are known as:

  • 15% plans (conceptual)
  • 30% plans (preliminary design)
  •  60% plans (design development)
  • 90% plans (pre-final design)
  • 100% plans (completed final design)

Public input on the design of a project is typically done around the 30%-60% plan phases.  A community open house meeting may be held by the City and design engineer to explain the project, answer questions and get input from the public.  By this time, enough information is known about the project to answer questions and have a good understanding of the needs of the project.

When the design of the project is complete, it will move on to the construction phase.  View projects in the “Construction” phase.

    The City’s original Master Area Drainage Study (MADS) was completed in 1999. The new MADS will reflect the significant changes in drainage by accounting for development, newer/better topographic data, and more accurate NOAA Atlas 14 rainfall data. The new flood study will determine the flow magnitudes, flow depth and flow velocities for the 10-, 100- and 500-year flooding events. The study will utilize a new 2-dimensional model to update the hydrology and hydraulics and be considered best available data to be used for all future planning studies, design projects and flood risk assessments.

    The revised flood hazard mapping studies will provide residents and business owners more accurate regulatory floodplain limits, which helps to determine the need for flood insurance.

    The City of Prescott Water Production Facility, located in the Town of Chino Valley, is the City’s primary source for water production. This project will replace the existing water booster facility in Chino Valley and will build the new intermediate pump station and tanks located near the Prescott Airport. This project will create a reduction in transmission pipeline pressure, improve production redundancy and provide additional storage capacity closer to Prescott.

    City of Prescott Water Production Facility (Chino Valley):

    The existing booster station is located in the Town of Chino Valley at the City of Prescott’s Water Production Facility, 251 N. State Route 89 (APN 306-23-077C). This project will consist of design and replacement of the City of Prescott water booster facility (buildings, boosters, electrical, controls). The facilities were originally built in the 1940’s and updates have been made to the facilities throughout the years to keep pace with the growing demand.  The current facility is undersized to meet future demands and the existing equipment has reached the end of its service life.  The facility replacement will ensure safe and reliable water supply to the City of Prescott service area. It is anticipated that the new booster station facility will have a firm pumping capacity of 14.0 MGD. By completing this project, the City will be able to provide additional reliability through higher efficiency and modernized equipment (buildings, electrical components, piping).

    Intermediate Pump Station Facility:

    The new intermediate pump station site is anticipated to be located about 1 mile north of Pioneer Parkway and 1 mile west of Willow Creek Road on currently undeveloped land; the site will be accessed from the east from Willow Creek Road. This project will provide the infrastructure to supply required redundancy to the existing water delivery system. This increases the overall reliability of the City’s water supply system by allowing the airport production wells to support the entire water system. Additionally, growth in north Prescott requires that a second pump station be constructed at the Intermediate Pump Station Facility that serves the surrounding pressure zone, Zone 110. The storage capacity required to meet fire demand and development growth needs have been determined by the City’s water model. The anticipated storage required for the intermediate pump station facility is 10 MG with the ability to expand to 15 MG. The intermediate pump station and the Zone 110 pump stations are anticipated to have a pumping capacity of 17.5 MGD and 8.4 MGD, respectively. Both pump station capacities will be evaluated further and confirmed during design.
