In 1979 the City engaged Associated Engineering Ltd. to complete a drainage study of this industrial area and as a result the City adopted a Drainage Development Cost Charge bylaw for the Industrial Area in 1980. Approximately 50% - 60% of the lands have developed since the adoption of the Development Cost Charge bylaw, however the City has not undertaken any drainage upgrading in the area, One of our current major concems is for the proposed stonn water detention area immediately north of the Mary Hill Bypass adjacent to the Harbour Street Pump Stations. 2. Scape of Work The stady will mcorporate the followmg: 1) Review the November 1979 Associated Engineering Services, Ltd. report - Industrial Area Drainage Study. 2) Review the 1980 Drainage Development Cost Charge Bylaw and calculations and comment on the applicability to current and future development. 3) Review all storm sewer as-built information for the entire drainage area net work and identify any deficiencies in the works installed or design allowances made to date. 4) Carry out general field surveys if necessary to supplement available plans supplied by the City. Establish proposed networks information on the "HYDSYS" Drainage Model _ Program. The City will purchase this program and run it on a PC 286 or 386. All information from the project will be provided to the City and will become the property of the City on completion of the project. The consultant must allow 20 hours of on-site staff training time in the City Engineering offices. Determine the best three or four over-all storm water management concepts for 5, 10 and 100 years retem frequency storms. Evaluate the various concepts based on appropriate criteria and using the "HYDSYS" model and make recommendations to the City as to the most appropmate concept. In close consultation with the City, select the one storm water management concept to be used and complete conceptual design for the proposed drainage works to the ultimate standard. Included in the conceptual design plans will be the identification of- ultimate requirements for additional Rights of Way acquisition, structures, retaining walls, pump station, and flood boxes.
