F. Authority for Spring Creek/Meridian Road Drainage Study ContractiheCiryoiKallspell Incorporated 1892 Telephone (406) 758-7700 FAX (406) 758-7758 Post Office Box 1997 Kalispell, Montana Zip 59903-1997 Date: October 2, 1996 To: Clarence Krepps, City Manager From: John Wilson, Assistant City Engineer Jcll� Re: Spring Creek Drainage Study This memo is a request for authorization to forego the process of Request for Proposals and enter into negotiations with Peccia Engineering for the analysis of the Spring Creek drainage basin and related storm drainage issues. Our recommendation for this approach is based on the following points: a need for continuity between this analysis and the storm drainage design for the Meridian Road Reconstruction project; a need for prompt analysis so this information may be incorporated into the Meridian Road project without delaying the design schedule; a high degree of confidence in the abilities of Peccia Engineering; and the estimated cost of these services is less than $20,000. Need for Continuity Peccia Engineering has completed their preliminary design for storm drainage improvements associated with the Meridian Road Reconstruction Project, including cost estimates for the City's share of the construction. The scope of work under the Meridian Road contract called for Peccia to apply existing storm drainage information and analyses by others. Although the Highway Department will pay the cost of drainage facilities to accommodate the area within the project limits, the preliminary plan includes improvements which will cost the City $494,000 to address critical drainage problems and flows entering at Three Mile and Two Mile Drives. It is important that these drainage solutions be included in the project, but we can expect a more detailed storm drainage analysis to provide the information necessary to refine the design and reduce construction costs. Also, Spring Creek is completely captured by the Meridian Road storm drainage system downstream from the reconstruction project. The unknowns about the Spring Creek drainage basin pose considerable uncertainty about the capacity of downstream pipes and the treatment capabilities of the existing outfall structure. A more detailed storm drainage analysis will allow the engineer to look at the Meridian Road drainage system as a whole. By performing the Spring Creek drainage analysis, the engineers at Peccia will coordinate the data acquisition and analysis to benefit the Meridian Road design as much as possible.

Duane Larson Ward IV October 2, 1996 Spring Creek Drainage Study Page 2 Need for Prompt Analysis By negotiating directly with Peccia Engineering we will move the completion date for this analysis ahead by approximately two months. With the Meridian Road project moving into the final design phase, it is important to have the results of this analysis as soon as possible. Estimated Cost of Services In negotiating a contract at an amount less than $20,000 we will comply with State procurement regulations governing architecture and engineering services. Please be aware that we have budgeted $50,000 for engineering analysis and design in this matter. If the analysis should recommend improvements such the whole or partial diversion of Spring Creek we will request proposals from interested firms for that phase of engmeermg. Given your approval, we will proceed with negotiations immediately.
