Recent & Current  CESI Projects

 

Pleasant Grove Watershed Mitigation Fee - City of Roseville

Civil Engineering Solutions, Inc. (CESI) was contracted by the City of Roseville to provide updated impact analysis and fee basis for the Pleasant Grove Watershed Volumetric Impact.  CESI revised the impact analysis for the development to-date, and planned developments within the watershed, and determined the estimated total impacts.  Additionally, impacts were determined for a variety of factors such as land use type and soils conditions, so that options in fee assessment could be presented.  The costs of the proposed volumetric storage facility at the Reason’s Farms property were compared to the amounts collected to-date, and fees were determined such that the ultimate costs of the facility would be paid for by the total build-out collections of the fee.

The fee update involved;

  • Identify all development activities which occurred subsequent to the initiation of the fee program
  • Determine volumetric impacts for the previous and planned future developments.
  • Determine an updated costs basis for the fee structure.
  • Determine an updated Fee assessment program.
  • Update the fee assessment spread as quarterly development reports were prepared by the City.
  • Prepare report document describing the project activities and supporting the proposed fee changes.

 

"E" Street Infrastructure Project - City of Lincoln     

Design of approximately:  ˝ mile of 48-inch RCP storm drain and appurtenances for relief of flooding in downtown Lincoln. Project included design of a 1.5-acre water quality basin and weir overflow to Auburn Ravine. Project cost $ 1.5 million.

 

 

South Lincoln - Master Drainage Plan SLMP-AIO-CLOMR

CESI provided engineering services to evaluate from a hydrologic and hydraulic analysis standpoint. All proposed system improvements. Project provides for ultimate expansion of City including retention and attention facilities. Prepared LOMR submittals for the remapping of 6 miles of Auburn Ravine, and roughly 10 miles of Ingram Slough and Orchard Creek. The estimated costs of facilities are $ 18,000,000.

Tehama - (Sun City, California) Master Drainage Plan         

 

Analysis for the watershed hydrology and stream hydraulics, evaluation of project impacts to peak flow rates and recommended mitigation, streambed stability analysis, and project storm water quality guidelines.

Performed several field visits to photo document, and measure key hydraulics features which could not be determined from the research information.   

The project is located along a ridge, west of Interstate 5, between the Cities of Red Bluff and Cottonwood and is tributary to three separate creek systems which ultimately discharge to Cottonwood Creek and the Sacramento River.

City of Wheatland General Plan Update                    

Prepared a background report and assessment of proposed and existing City drainage facilities. CESI recommended a scope of new drainage improvements, City wide.

Provided technical support for drainage analysis for various drainage alternatives and hydrologic analysis of pre and post development conditions.

This project is ongoing.

Regional University Specific Plan

The proposed Regional University Specific Plan (RUSP) is wholly contained within the Curry Creek watershed that ultimately drains to the Natomas Cross Canal discharge to the Sacramento River, west of the project. The RUSP includes roughly 1130 acres of mixed land use. 

The hydrologic analysis (HEC-1) included with this project provides analysis of the 16.6 square mile of tributaries to Curry Creek, upstream of the project. All calculations and analysis included in this study were prepared in accordance with the “Preliminary Plan” requirements of the “Stormwater Management Manual (SWMM)” dated February 1994 and the SWMM Addendum 1, dated October 1997.  The existing condition HEC-1 model is based on the currently accepted models of Curry Creek that includes the proposed development within the West Park and Placer Vineyards developments. The project HEC-1 watershed files were generated using the Placer County Pre-processor utility and the PDP precipitation generation software.

Hydrologic and hydraulic analysis’ were also performed for the proposed phasing options of the project to show that adequate mitigation would be provided throughout the project construction and sequencing.
