POSITION PAPER Board Meeting Date: April 3, 2014 Subject., AUTHORIZE THE GENERAL MANAGER TO AMEND AN EXISTING PROFESSIONAL ENGINEERING SERVICES AGREEMENT WITH RMC WATER AND ENVIRONMENT FOR THE COLLECTION SYSTEM MODELING UPGRADE, DISTRICT PROJECT 8419 Submitted By. Initiating DeptJDiv.: Justin J. Waples, Assistant Engineer Engineering /Environmental Services Div. REVIEWED AND RECOMMENDED FOR BOARD ACTION: N. Hodges — Provisional Senior Engineer D. Gemmell — Environmental Services Division Manager Roger S. Bailey General Manage ISSUE: Board of Directors' authorization is required for executing a professional services agreement amendment that will result in the contract amount to exceed $100,000. RECOMMENDATION: Authorize the General Manager to execute an amendment to the Professional Engineering Services Agreement with RMC Water and Environment. FINANCIAL IMPACTS: Raise the existing contract cost ceiling of $97,732 to $120,000. There are sufficient funds allocated to the associated District Project 8419, Collection System Modeling Upgrade, to accommodate this amendment. ALTERNATIVES /CONSIDERATIONS: An alternative would be to let District staff complete the work associated with this amendment, as time permits, however, at this early stage of the project, District staff does not possess the necessary skillsets or the time to efficiently undertake this work. The most cost - effective option is to have the consultant undertake the tasks mentioned in the next section of this document. BACKGROUND: The District commenced this project in 2013, to transition from an unstable proprietary steady state model which is unsuitable for much of the District's complex collection system; to a commercially available dynamic model that has the potential to accurately simulate the hydraulic complexities of the District's collection system, and at the same time provide a platform that can safely and routinely share collection system data with the District's new GIS system. This project will provide the District with a platform that is crucial to the effective management and planning of the collection system. Moreover, it will bring the District in line with its peers in the wastewater industry that have been optimizing their collection systems with the use of dynamic models for many years, and will provide essential data necessary for collection system asset management.

District staff is tasked with the actual implementation. Upon starting work on the new dynamic model software, numerous connectivity issues were identified with the pipe network that was imported from our GIS system. This was not anticipated and only became apparent after the import of GIS data. Tasks to be undertaken with the additional funds include creation of a continuous trunk network geometry using existing GIS data, define the model trunk system and create excel spreadsheets, ready for use by District staff to commence populating profile and invert elevations for the dynamic model. Additional tasks include preparing a brief technical memo to discuss conceptual alternatives for undertaking localized capacity studies, and preparing an additional technical memo to discuss conceptual staffing requirements essential to prudently operating and maintaining the critical platform. The project is included in the 2013 -14 Capital Improvement Budget on page CS -26. Staff has determined that there are adequate funds available and that the expenditure requirements are consistent with the Collection System Program. Staff has concluded that this project is exempt from the California Environmental Quality Act (CEQA) under District CEQA Guidelines Section 15301 since it pertains to a software platform. Approval of this project will establish the Board of Directors' independent finding that this project is exempt from CEQA. RECOMMENDED BOARD ACTION: Authorize the General Manager to execute a professional services agreement amendment with RMC Water and Environment, with a cost ceiling of $120,000 for the Collection Systems Modeling Upgrade, District Project 8419.
