TASK 3 RAINIER/GRADY TODI HYDRAULIC ANALYSIS
This task outlines the work to be completed, deliverables, and deadlines for the Rainier/Grady
TODI Hydraulic Analysis.
Task 3 Activities
301. Monthly Progress Report - Prepare two (2) monthly project progress reports to
accompany each monthly invoice; identify accomplishments for the invoiced month,
planned work for the next month, and identify current or potential problems or changes.
The reports will also include a narrative describing progress measured against budget
and schedule. In the event of schedule or budget lag, the report will indicate a plan to get
the project in line with the schedule and budget.
302. Client Coordination - Perform project management and coordination with the City.
a. Manage the Consultant project team to track time and budget, work elements
accomplished, work items planned for the next period, manpower, scope changes,
time and budget needed to complete the project.
1) Maintain a working project.
2) Review project status, including scope, budget, and schedule.
303. Future Flow Development - The Consultant will develop a loading tool from the
previous LRWWMP for the Rainier/Grady TODI area to develop sanitary flow scenarios
based on one no-change alternative and two proposed development alternatives. The
loading too will be setup based on tax parcels. Flow factors will be developed for the
types of proposed redevelopment. The flow factors will then use used with the loading
tool to generate projected flows for the alternatives to be input to the model at the
appropriate connection points.
304. Future Flow Collection System Evaluation – The alternative scenarios developed will
be tested with the model for the current and build-out planning years to evaluate the
potential system impacts. The alternative scenario flow loads will replace the current
loads in the Rainier/Grady TODI are in the model. Both dry weather conditions and the
design storm will be tested, for a total of 12 model runs, 6 for the current planning year,
and 6 for the buildout planning year. The results of the runs will be compared with the
results from the LRWWMP to evaluate implications for the current collection system.
305. Modifications Development – If the modeling indicates future deficiencies are more
severe than previously identified in the LRWWMP, preliminary modifications will be

developed and tested with the model to meet city performance criteria for the alternative
scenarios.
306. Technical Memorandum 1 – Prepare a Technical Memorandum (TM) summarizing the
work completed, results, and potential recommendations. A draft TM will be available
within 6 weeks of notice to proceed.
307. Meeting No. 1 – Meeting to Review Modeling Results. Prepare PowerPoint presentation
and facilitate meeting with City to review the modeling results and potential
recommendations.
Deliverables:
Technical Memorandum 1.
Meetings:
Meeting No. 1 – Meeting to Review Modeling Results.
Assumptions:
Model developed for LRWWMP will not need additional calibration.
The redevelopment alternatives will not increase I/I rates.
Design storm boundary conditions including King County Interceptor flows are suitable
for this effort.
Cost estimating of any improvements is not included under this evaluation task.
