BACKGROUND The Boxelder Creek/Cooper Slough Basin encompasses approximately 265 square miles beginning at the Colorado/Wyoming border and extending southward into eastern Fort Collins where it terminates at the Cache La Poudre River. The basin is primarily characterized by farmland with isolated areas of mixed -use residential development and limited commercial development. B. PURPOSE Recent hydrologic modeling of the basin was completed by Anderson Consulting Engineers, Inc. as documented in theDecember 2001 final summary entitled "Hydrologic Evaluation for Existing Drainage Facilities". The hydraulic modeling and floodplain analysis of Cooper Slough and Boxelder Creek was recently completed and a draft summary entitled "Hydraulic Evaluation for Existing Drainage Facilities" submitted for review to the City on December 14, 2001. This phase of the master planning effort includes the identification of existing flooding problems within the basin as indicated by the results of the hydrologic, hydraulic and channel stability work. Properties, critical facilities and road crossings which are potentially impacted by the 100-year flood will be specifically identified and damages associated with the 100-year flood determined (existing conditions, existing facilities in place). A stream stability analysis and a water quality assessment will also be included to facilitate problem identification within the study corridor. II. PHASE A — PROBLEM IDENTIFICATION A. DATA COLLECTION AND REVIEW 1. The Professional shall meet initially and as appropriately thereafter (up to three additional times) for all work involved in the Problem Identification to: a. Insure compliance with the services required by the Agreement. b. Obtain existing data and general information, including confirmation of known problem areas within the drainage basin. c. Procure information relative to right-of-way limitations and potential hazards due to flooding. P:\COFC 16\Word Dm ments\COFC 16pmblemidsow.doc ANdERSON CONSUITINq ENgINEERS, INC. EXHIBIT A SCOPE OF WORK for BOXELDER CREEK/COOPER SLOUGH PHASE A -PROBLEM IDENTIFICATION Page 2 of 7 d. Avoid duplication of effort whenever possible by utilizing existing information available from other agencies applicable to this study. e. It is assumed that the Professional will be responsible for providing minutes to the meetings conducted during the Phase A Problem Identification. 2. The Professional shall furnish to the City, for their review and approval, detailed scheduling including target dates for the completion of the major tasks associated with completion of this phase of the project. 3. The Professional shall utilize the City "Storm Drainage Design Criteria and Construction Standards" manual and FEMA contractor study guidelines where appropriate and applicable. 4. The Professional shall conduct field verification visits, as necessary, to confirm the data pertinent to channel stability, existing or potential flooding areas, etc., or to collect additional data to facilitate the Phase A Problem Identification. The collection of field data may include the following: a. Geomorphology/Stream Stability Data i. Additional field data will be collected to supplement the field reconnaissance efforts included in the hydrologic analysis. The existing bed and bank erosion features will be inventoried; existing structures that impact the stability of the channel will be identified. ii. See Paragraphs 11. C. 2. a. and b (Stream Stability Analysis). b. Water Quality Data i. Determination and delineation of wetland areas will be provided by the City in Archlfo format. ii. Data on aquatic, wetland, and riparian habitat will be provide by the City in Arclnfo format. The Professional shall determine ownership boundaries along the study area watercourse. This determination shall establish where various types of easet*ents-eed rights -of -way are located and will not require an actual determination of the names of the owners. This information will be obtained from the City's GIS Department. PACOFC16\Word Documents\COFC16pmblemidsow.doc ANdERSON CONSUITINg ENgINEERS, INC. EXHIBIT A SCOPE OF WORK for BOXELDER CREEK/CobPER SLOUGH PHASE A -PROBLEM IDENTIFICATION B. MAPPING Page 3 of 7 The City will provide new digital mapping of all areas to be used for this study. The Professional shall be responsible for producing all other suitable maps for reproduction of reports. C. STREAM STABILITY ANALYSIS 1. The stability study is intended for use in developing practical alternative improvements for mitigating adverse impacts on the channel system. The study will require a review and summary of past studies that have been completed in the basin. This data, along with a field review, will be used for completing stream stability evaluations and recommendations. 2. Geomorphic Analysis a. Qualitative Analysis - From Existing Reports and Field Review, Complete the following: i. Describe the physical features of the drainage basin. This shall include those natural and man-made features which affect the drainage basin based on qualitative observations and interpretation of available data and field reconnaissance. ii. Describe the fluvial system characteristics using the review of previous work and data applicable to the study area, historic and recent maps and aerial photography, notes from field surveys and inspections, historic and recent channel profile and planform information on land use changes, and changes in stream hydrology and hydraulics over time. iii. Historical data from previous reports will be evaluated to characterize any trends related to erosion and sedimentation, as well as the natural patterns and dimensions of the channel system, and stream response and evolution. Stability of the system relative to profile changes, watershed changes, bank erosion and sedimentation is of particular concern. iv. The effects of diversion for municipal and industrial use and for irrigation and the effects of regulation on streamflow are to be assessed qualitatively. v. Correlate the changes in the basin to significant changes in the morphology of the channel system. Potential future changes in the morphology of the channel system shall be described based upon the natural conditions of the existing watershed and the expected development conditions, observed trends, and geomorphic principles. Stream morphology changes shall be characterized as influenced by historic, existing or future conditions. PAC0FC16\Word Documents\C0FCI6pmb1emidsow.doc ANdERSON CONSUhINq ENGINEERS, INC. EXHIBIT A SCOPE OF WORK for BOXELDER CREEK/COOPER SLOUGH PHASE A -PROBLEM IDENTIFICATION b. Quantitative Analysis i. Summarize general results. ii. Tabulate estimated stable slope for reaches previously defined. Page 4 of 7 iii. Determine buffer limits using estimated stable slopes, and field observed data. iv. The field observations will be documented on a map and will be included in the technical documentation. Specific problem areas will be identified and included on the problem identification mapping. v. Delineate buffer limits using estimated stable slopes, field observation, and minimum criteria. Include the erosion buffer limits on the problem identification mapping along with the floodplain boundary, habitat ratings, wetland preliminary identification, symbols for unstable banks and problem areas highlighted and referenced to a written description. 3. Products from stream stability analysis include, but are not limited to: - Stream stability summary discussing the above information, such as, qualitative and quantitative analyses, prediction of trends for aggradation and degradation along channels, scour potential, historical channel patterns, and descriptions of characteristics of the existing natural sections of the stream. - The following information on drawings: a.
