ASCE North Coast Chapter’s 2011 Project of the Year Tish ... Civil Engineering, Building Design,...

Advancing the quality of life for generations to come

Tish Non VillageOwner: Bear River Band of the Rohnerville Rancheria

Services: Survey, Hydrogeology, Geology and Geotechnical Engineering, Civil Engineering, Building Design, Construction Materials Testing, Special Inspections, and Project Management.

Timing: 2007-8 Fee to Trust Transition and Master Planning, 2008-9 Design and Engineering, 2010-11 Construction

Financials: Phase 1 represented ~$14.5 million in improvements. The total project capital outlay to date is on the order of magnitude of ~$50mm for Phases 1 and 2. Additional housing units will increase this amount another $4-6mm within the next 2-3 years.

Project Objectives• Autonomy

– Fundamental to many Tribal governments is their desire to be autonomous and self-sustaining.

• Future Growth– Increasing population– Improved health and well being of the membership– These growth objectives provide a foundation for becoming a premier resort

destination on the north coast.• Good Neighbors

– Rural Neighbors and community involvement– Political leaders, regulators, and local government staff involvement in plan

development.– Recurrent communications .

• Access– Space utilization– Wetlands, nature and cultural interpretive trails


Project Objectives• Housing

– Single Family and Multifamily accommodations for up to 85 families– Units ranging from 2 bedroom apartments to 4 bedroom single family

residences.• Environmental Sustainability

– Low impact to the environment is coherent and consistent with Tribal culture.– Wetlands and Storm water Management– Sustainable Home Designs

• Budget and Schedule– Internal tribal grant staff working together with LACO staff formed a hybrid

funding strategy (BIA, IHS, and ICDBG).– Rancheria’s general fund– Immediate membership housing needs, relocating from various areas around

western U.S.– Immediate needs of additional water and wastewater capacities required by

planned growth of hospitality operations.


Project Components• Site Master Planning

– Coving– Roadway alignments– Variable housing setbacks, green space

and privacy.• Engineering Infrastructure

– Sloping site– 1.1 miles of Roadway - Alignments

• Existing topography• FP-03 slope and transition

constraints• Unsuitable soils

– Wetlands and stormwater peak attenuation.

– Placement of well, water facilities, wastewater facilities

– No lift stations


Project Components• Water Resources

– Accomplished minds collaborating to produce exceptional well performance

– Engineered well produces 230gpm vs. non-engineered wells in the area in same aquifer yielding 120gpm or less.

– Preliminary designs and performance specifications for manganese greensand and activated carbon pressure filter treatment system.

– 200,000-gallon glass lined bolted storage tank, LACO tank foundation.

– Treatment facility appearance designed to match and complement residential units.


Project Components• Wastewater Infrastructure

– Performance specification for a packaged plant.– Tertiary quality produced is consistent with Title 22 for unrestricted use.– Disposal field is a shallow pressure assisted micro drip system located in the

community sports field.• Residential Housing

– 26 Units associated with Phase 1.– Units constructed in three phases concurrently with other project infrastructure.


Project Challenges• Fee-to-Trust Process and Project Startup

– The project site was going through the fee-to-trust conveyance in parallel with the development of the project.

– FTT discretionary approvals and potential appeals = schedule forecasting challenges.

– Which jurisdiction governs - State or Federal? Schedule/Risk Management.• Roadway Alignments

– Coving and Wetlands – Topography, FP-03, and Unsuitable soils


Project Challenges• Concurrent Construction and Logistics

– Residential Housing, Roads, Utilities, Water and Wastewater facilities constructed concurrently.

– Construction of housing through winter season and maintaining access.– Managing unauthorized use of roads which were shut down for winter season.


Project Challenges• Commissioning

– Training of tribal staff and rapid turnover of staff over a relatively short period of time.

– Housing units completed before utilities (no heat available) and the risk of humidity and mold.

– Bringing water and wastewater systems online and coordinating these elements with start up of new hotel and occupancy of residential housing.

– Issue with disposal field operations• Issues with PLC valve actuator operation.• Shortage of qualified field staff to assist tribal operator systems operation• I&I issues result in winter time peak inflows exceeding WWTP capacity• Managing speculation by the client• Saturation of some disposal field zones

– Managing speculation by the client


Project Achievements• Over the course of this multi-year project, numerous challenges were overcome

and a successful project resulted. The accomplishments were interconnected in a way that made this project unique and noteworthy

– Despite over-saturated soils, winter construction, managing multiple contracting teams the project met the schedule objective.

– Meeting the schedule objective was critical with planned start up of Phase 2 project elements which included an expanded casino, new hotel, community center, and additional roads, utilities and housing units.

– The financial risk associated with a delay in the opening of $21mm hotel was entirely avoided.

– Tish Non Village, the expanded casino, and new hotel have adequate water supply due to exceptional yield of the engineered well.

– The specification and performance of the packaged WWTP was a critical planning and logistics component to meeting the overall project schedule.

– Economic Boost at a critical time for our region’s ailing economy - $14.5mm over a 14 month period and an additional $35mm associated with Phase 2 over a 20 month period.
