As part of this contract addendum, CH2M HILL INC. will be authorized to perform Alternative Analysis in other high priority drainage basins throughout the City. At the City's discretion, any or all of the following tasks can be performed for a selected stormwater drainage basin. ~ Description A Drainage Basin Data Collection B Alternative Development C Alternative Evaluation D Workshop with City Staff E Final Technical Memorandum F Coordination with Program Manager Task A. Drainage Basin Data Collection CH2M HILL INC. will obtain from the City existing relevant data and documents for the particular drainage basin, including, but not limited to: . Existing storm sewer maps, including elevations, materials of construction, and sizes. . Land use maps and information . Location of state and county-maintained roadways and drainage facilities . Existing water quality data The following activities will be performed as part of the data collection work and are required before stormwater improvement alternatives can be developed: Subtask A 1: Storm Sewer System Delineation and Hydraulic Data The existing storm sewer system will be simplified into a network of critical nodes (manhole or cluster of catch basins) and pipes to be used in the analysis. The relevant 9 '. facility data will be obtained from City records and stored in computer. spreadsheet format developed as part of the work in Task Order NO.1. The data required for the collection system includes the following: . pipe length . pipe size and shape . pipe construction material . ground surface elevation at all nodes Subtask A2: Drainage basin Delineation and Hydrologic Data The City's drainage basin boundary will be verified and modified. Drainage basins will then be delineated for each drainage node in the system. Drainage basin delineation will be based on available topographic information or the street grades obtained from sanitary sewer profile sheets. The relevant hydrologic parameters will be calculated for each drainage basin and stored in computer spreadsheet format. The required hydrologic data includes the following: . drainage basin area . directly connected impervious area (DCIA) . road classification (A, 8, or C) at each drainage node . total miles of each road class within the drainage basin Task B. Alternatives Development At the City's discretion, up to three stormwater improvement alternatives may be developed for the selected drainage basin: 1. Pipe Alternative 2. Drainage Well Alternative 3. Combination of Pipes and Drainage Wells The alternatives will be developed with computer spreadsheet models which perform the necessary hydrologic and hydraulic calculations. The design storm(s) for a given drainage basin will be determined by the road classifications within the basin, as outlined in the Stormwater Policies and Procedures Manual. CH2M HILL will prepare a draft technical memorandum (TM) summarizing the alternatives development, hold a review meeting with the City, and incorporate comments into a final TM. Alternative 1: Pipes The basin specific hydraulic and hydrologic information collected in Task A will be incorporated into the spreadsheet model for sewer design. Design hydraulic 10 , . gradelines will be established using ground surface elevations, such that.the flooding criteria identified in the Storm Water Planning and Procedures Manual, as part of Phase I, is met. Using the spreadsheet model, a conceptual design consisting of new storm sewers will be developed and refined for the selected basin. Alternative 2: Drainage Wells The basin specific hydraulic and hydrologic information collected in Task A will be incorporated into the spreadsheet model for drainage well design. Using the spreadsheet model, the existing collection system capacity will be analyzed and compared to the calculated surface runoff. A conceptual design consisting of drainage wells which supplement the eXisting collection system will be developed and refined for the selected basin. - - Alternative 3: Combination of Pipes and Drainage Wells Depending on the particular drainage basin, it may be desirable to combine Alternatives 1 and 2 and develop a combination of drainage wells and pipes to meet the flooding criteria. This may be advantageous for basins with high DCIA's which would require excessively large sewers to meet the conveyance needs. For this alternative, the spreadsheet model will be used to determine a combination of wells and pipes such that pipe sizes do not become excessive. De/iverables (optional): 11-1 CH2M HILL will prepare a draft TM summarizing the results of the alternative development. Five copies will be provided to the City. 11-2 CH2M HILL will revise the alternatives development based on comments from the meeting and redraft the TM. Five copies will be provided to the City. Task C. Alternatives Evaluation This task includes a planning level cost estimate and water quality impact evaluation for the alternative(s) developed in Task B. If more than one alternative was developed, the alternatives can be compared so that the best alternative can be selected. At the City's discretion, up to three subtasks can be selected. CH2M HILL will prepare a draft technical memorandum (TM) summarizIng the alternatives evaluation and hold a workshop with the City (Task D) to select the best alternative. Subtask C1: Cost Analysis 11 '. Planning-level present worth and equivalent annual cost estimates willlJe developed for the alternative{s). They will be based on facility cost (materials, design, and construction) and general operation and maintenance (O&M) costs (labor, equipment, and materials). Subtask C2: Water Quality Analysis Pollutant loads to the receiving water will be calculated with and without the improvements developed in Task B. The pollutant load reduction for each pollutant of concern will then be calculated. Pollutants which can be included in the analysis are as follows: 1. 5-day biochemical oxygen demand (BOO-5) 2. Chemical oxygen demand (COD) 3. Total suspended solids 4. Total dissolved solids 5. Total nitrogen 6. Total ammonia + organic nitrogen 7. Total phosphorus 8. ~issolved phosphorus 9. Cadmium 10. Copper 11. Lead 12. Zinc Representative pollutant concentrations for stormwater runoff from different land uses will be taken from data collected by OERM. Loading estimates will be calculated for each drainage basin as the product of annual average runoff volume, pollutant event mean concentrations, and the average pollutant retention capacity of existing and "improvement" facilities. Subtask C3: Alternative Comparison If more than one alternative is developed in Task B, the alternatives can be compared on a cost basis and on a water quality impact basis so that the most effective alternative can be selected. Deliverable (optional): 11-3 CH2M HILL will prepare a draft TM summarizing the results of the alternative evaluation. Five copies will be provided to the City. Task D. Workshop With City CH2M HILL will conduct a workshop with City staff to discuss the results of the alternatives evaluation. The workshop will focus on how well the alternative{s) meets the level-of-service goals and/or budgetary constraints.
