CITY OF MERIDIAN
Sanitary Sewer System Improvements in Conjunction with Road
Improvements on Franklin Road between Ten Mlle Road and Linder Road
PURPOSE
The Engineer's scope of services. time of completion and compensation shall be as set
forth herein. Services shall generally be described as Engineering Consulting Services.
TASK 0766.02 -SANITARY SEWER SYSTEM IMPROVEMENTS
The following is a detailed scope of work to provide professional services for design of
sanitary sewer system improvements to be constructed in conjunction with roadway
improvements for the Franklin Road -Ten Mile Road to Linder Road Improvements
Project.
The professional services required are to prepare plans, bid schedule, special provisions
and cost estimate to construct sanitary sewer system improvements on Franklin Road.
The anticipated design elements include the following:
A. PROJECT ADMINISTRATION AND QAIQC
Consultant will staff and manage the project team to provide project deliverables,
monitor budget and schedule, and coordinate with the City of Meridian, ACHD and
project stakeholders on a regular basis or as directed.
Team meetings will be conducted bi-monthly (or as needed) throughout the duration of
the project.
Parametrix will send a letter to all property owners within the project limits to determine if
they desire new sanitary sewer stubs to their property. The letter will advise them of the
project, advise them the City will install a service stub to their property at their
documented location. and advise them of the estimated design and construction costs
that must be collected before construction of the stub. A copy of the letter will be sent to
the City for approval of the content and wording prior to being issued.
Perform and provide the City of Meridian with copies of relevant correspondence with
other project stakeholders (e.g ACHD, private utilities, property owners)
Products ~ Deliverables:
• Bi-monthly team meetings
• Meeting summaries
• Monthly progress reports (6 month duration assumed)
• Project schedule updates
• Property owner letter
B. TOPOGRAPHIC SURVEY
A topographic survey has been previously completed for this project that includes the
Franklin Road corridor between Ten Mile and Linder. However, additional topographic
survey will be required between Franklin Road and the entrance to the Whitestone
Subdivision in order to accurately design the sanitary sewer system connecting to the
Whitestone sanitary sewer system.
Topographic survey shall define a corridor 100 feet wide centered 50 feet west of the
Calnon Enterprises property line. Surveying and mapping senrices will include the
following:
1. Prepare and hand deliver property owner notices informing the owners of the
required temporary access to their properties in order to complete the
topographic survey. The letter will briefly describe the proposed
improvements and provide contact information for the City of Meridian and
Parametrix for any questions or concerns.
2. Perform topographic cross-sections along the proposed sanitary sewer
centerline at 100 foot intervals (100 foot wide) for design of the project.
3. Conduct survey necessary for location of any existing utilities, structures,
fences, storm water and/or irrigation facilities that may be impacted by the
proposed sanitary sewer line.
4. Establish benchmarks at approximately 500 foot intervals along the proposed
centerline alignment on permanent objects outside of the construction limits.
5. Conduct field survey needed to delineate the existing property boundary for
the Calnon Enterprises parcel.
Products & D®liverables:
• Field Survey Data.
C. SANITARY SEWER SYSTEM IMPROVEMENTS
1. Review the existing comprehensive plan to conservatively estimate the
sanitary sewer system capacity needs based on existing and projected
development within the project corridor. The estimate of capacity needs will
be provided to the City for review and comment.
2. Where possible all proposed utility improvements will be designed within the
proposed right-of-way limits or existing utility easements granted to ACRD.
Where adequate right-of-way or easements do not exist we will prepare
temporary and permanent construction easements to cover the utility
improvements. Where adequate right-of-way exists alt proposed utility service
stubs will be designed to extend ten feet beyond the proposed right-of-way
line so that the service extends outside the roadway prism for future
connection.
3. Design and provide plans to Install approximately 3750 LF of new 18°f?J
sanitary sewer main in Franklin Road and 1250 LF of new 12°fd sanitary
sewer main south of and perpendicular to Franklin Road. Both pipe sizes will
be verified for adequate opacity prior to beginning the design.
The sanitary sewer main installation will begin with a cronnection to the
existing 18°!7~ main at the northeast comer of the Ten Mlie Road /Franklin
Road intersection. The sanitary sewer main will then be routed east within
Franklin Road and south to avoid the existing Franklin Road Bridge while
crossing under the Ten Mile Canal in a concrete encased steel casing. All
requirements for crossing the Canal will be met. The sanitary sewer main will
continue east within Franklin Road approximately 3500 LF to a proposed
manhole near the entrance to the Sanitary Services Company. The sanitary
sewer main will then tum south and run 400 LF before crossing under the
Vaughn Lateral Irrigation Ditch. The sewer main will continue south 450 LF
before crossing under the Ten Mile Canal in a concrete encased steel using.
The sewer main will continue south 400 LF and connect to the existing
sanitary sewer system at the Whitestone Subdivision where it will terminate.
The termination will include the abandonment of the existing sewer lift station
and will also be designed to allow for extending approximately 1200 LF
further south in the future.
4. Prepare and submit a 404 permit for cxossing the Vaughn Lateral and Ten
Mil® Canal.
5. Determine size and location of sanitary sewer fine service stubs for up to 5
parcels and show on the project plans. The locations are anticipated to be at
the proposed new commercial approaches within the project limits along with
a service line to the residential parcel for Walter Morrow.
6. Determine permanent construction easements from approximately 5 property
owners to cover the work associated with the construction of the service
stubs. Legal descriptions will not be prepared for each permanent easement
under this scope of work.
7. De#ermine permanent construction easements from approximately 3 properly
owners to cover the work associated with the construction of the sanitary
sewer mainline south of Franklin Road outside of existing right-of-way. Legal
descriptions will not be prepared for each permanent easement under this
scope of work.
8. Adjust approximately 4 existing sanitary sewer manholes to grade.
9. Assist in establishing a Joint Effort Agreement between the City of Meridian
and the Ada County Highway District (ACRD) which will allow the City to pay
for all sanitary sewer improvements required for the project.
10. Prepare special provisions, opinion of probable construction cost and a bid
schedule.
11. Coordinate with City of Meridian Development Services to assure compliance
of review checklist requirements.
D. DESIGN SUBMITTAL INFORMATION
1. The sanitary sewer system improvements will be included in the plan set for
the Franklin Road -Ten Mile Road to Linder Road Improvements Project.
