1. Increasing the total basin depth to 25’.
2. Recreational trail with landscaping around basin.
3. Maintenance access path and ramp.
4. Fencing, if needed.
5. Linwood Street preliminary design.
a. 2-lane collector per standard detail P-3.
b. Vertical and horizontal alignment.
6. Backfill and compaction of Linwood Street embankment and basin west of Linwood Street.
7. Relocation and redesign of existing outfall structures.
8. Modification or replacement of Modoc Ditch Inlet structure for trail purposes.
9. Temporary parking lot design for trail users, if feasible.
10. Subdividing the Modoc Basin parcel for the dedication of Linwood ROW.
Attached you will find our proposed scope of work, schedule, and fee needed to complete this project.
SCOPE OF WORK

The above Task 1 services will be provided for a Fixed Fee of $19,976. This task assumes up to five (5) in-person design review meetings. 4Creeks will be available to attend additional in- person or virtual meetings, as needed and approved by the City on a Time and Materials basis.
TASK 2 – PROJECT INITIATION
Upon contract authorization, the Project Initiation task will allow for 4Creeks to research, compile, and present to the City a list of known issues and conflicts within the site parameters and propose what design improvements will be needed to address these issues. 4Creeks will:
1. Conduct a site visit and assess the conditions involving the design of the project.
2. Develop a list of issues, questions, and coordination items.
3. Identify the necessary improvements needed for a complete design.
4. Schedule and attend the project kick-off meeting.
5. Prepare agenda for the project kick-off meeting.
6. Review and refine the project schedule included in the contract agreement.
7. Define City and Consultant responsibilities.
8. Review and discuss the scope of work and budget per the contract agreement.
9. Prepare and distribute project kick-off meeting notes.
The above Task 2 services will be provided for a Fixed Fee of $3,680. This task assumes one (1) project kick-off meeting. Any additional items requested, not specifically mentioned above will be billed as “extra” on a Time and Materials basis.
TASK 3 – TOPOGRAPHIC SURVEY
4Creeks will conduct a topographic survey of the approximately 50-acre Modoc Basin, as well as adjacent ditches and roadway improvements. Said survey shall include the following items:
1. Detailed topography of existing roadway (curb, gutter, lip crown) at 50’ interval/stations as necessary.
2. Existing observable improvements within project limits or directly adjacent thereto that may be affected by the project.
3. 100’ x 100’ grid.

5. Striping and pavement markings.
6. Concrete/sidewalk at 50’ interval/stations as necessary.
7. Tie into the City of Visalia benchmark system.
8. Tie in adjacent centerline or property line monuments for baseline control of site and rotate as necessary. (City of Visalia Coordinate System, LS 20-17)
9. 4Creeks will then prepare the topographic survey map. Property boundaries will be prepared based on record data and field monumentation.
10. Any title or agency documentation shall be provided by the City and/or their agents.
The above-described Task 3 services shall be provided for a Fixed Fee of $17,325. Any additional items requested, not specifically mentioned above will be billed as “extra” on a Time and Materials basis.
TASK 4 – GEOTECHNICAL INVESTIGATION
4Creeks’ subconsultant, Krazan & Associates, will perform a geotechnical investigation.
Krazan will drill ten (10) exploratory borings within the proposed project site to evaluate the subsurface soil conditions. The exploratory borings will be advanced to depths ranging from
approximately 10 to 25 feet or auger refusal. In addition, four (4) bulk subgrade samples will be collected for R-Value testing. During drilling operations, penetration tests will be performed at regular intervals to evaluate the soil consistency and to obtain information regarding the engineering properties of the subsoils. Soil samples will be retained for laboratory testing. The soils encountered will be continuously examined and visually classified in accordance with the Unified Soil Classification System. All fieldwork will be done under the supervision of a Geotechnical Engineer or Senior Geologist.
Laboratory testing will be dependent on the results of the field testing and sampling program, as well as consideration of the foundation system, which is most practical and cost-effective for the project. Currently, a series of dry density determinations, moisture contents, expansion tests, direct shear tests, R-Value and consolidation tests are anticipated. The results of the field exploration, laboratory testing, and engineering analysis will be presented in a formal report after thorough discussion of the project findings with project team.
The Geotechnical Engineering Investigation Report will address the following items:
1. Introduction.
2. Site Description.
3. Geological Setting.
4. Soils Profile and Subsurface Conditions.
5. Groundwater Conditions.
6. Engineering Conclusions and Recommendations.

4Creeks will prepare the Preliminary Basis of Design and 30% Preliminary Engineering Design to coordinate the design approach, identify feasible site features, and document the project methodology. The preliminary design and basis of design will ensure that both parties agree on design parameters as the project advances into detailed civil design.
The Basis of Design will evolve throughout the design phase and will be finalized after the 60% submittal. The Preliminary Engineering Design will be developed in accordance with City of Visalia Standards and applicable Caltrans Standards, incorporating agency coordination, design concepts, and cost estimating.
This task shall include the following items:
1. Identify applicable design standards and guidelines.

City of Visalia Responsibilities
1. Provide potholing/as-builts as necessary to determine true utility locations.
2. Provide responses to Consultant’s questions within two (2) days throughout the project.
3. Attend and participate in monthly project coordination meetings and City review meetings.
4. Provide expedited permits and City review to maintain the project schedule.
5. Provide standard template specifications.
Assumptions
Based on information provided by the City of Visalia, the scope of work was developed based on the following assumptions:
1. All right of way acquisition, dedication, subdivision, and parcel mapping services are excluded from this scope of work. The City of Visalia owns all parcels involved in the project and will complete any necessary parcel splits, right of way dedications, or mapping internally. Therefore, the task listed in the original scope of work titled - Professional Land Surveyor Services - shall not be required under this contract.
2. It is assumed that there will be no Caltrans encroachment permitting needed for this project.
3. Excluded from this scope of work is the preparation of a storm water pollution control plan and dust control plan and any fees associated with the preparation and approvals of said plans.
4. It is assumed the project can be covered by CEQA exemptions and the City will be performing this work.
5. It is assumed that 4Creeks will not design the canal crossing running along the northerly limits of Modoc Basin.
6. It is assumed we will not be designing the full road. The improvement plans will only include grades to the subgrade. 4Creeks will take into consideration the full road build out, but will rely on the developer to finish those improvement designs.
7. All fixed fees and time and materials services are determined using the amended fee schedule under our current on-call engineering agreement. Optional services in the future will be assessed, and estimates may be updated and provided in the event the agreement and fee schedule has been updated. Any work to be completed at prevailing wages would be based on the current prevailing wage rates.
We are pleased to submit this proposal and look forward to the opportunity to build a strong working relationship with the City of Visalia. Should you have any questions or require additional information, please do not hesitate to contact us.
