Il. SCOPE OF SERVICES
Task 1: Site Investigation
1.1 Survey Coordination
ENGINEER will examine any existing survey information or other available data to
determine existing drainage patterns and topography. ENGINEER shall coordinate
additional survey for:
• S.W. 32"d Street between S.W.261h Terrace and Anglers Avenue/Ravenswood
Road;
• S.W. 3 1"Street between S.W. 26 h Terrace and Anglers Avenue/Ravenswood
Road;
• S.W. 361h Street between S.W. 26`h Terrace and S.W. 251h Avenue;
• S.W. 261h Terrace between S.W. 361h Street north to I-595;

Road;
1.2 Utility Coordination
ENGINEER will coordinate with utility companies in which have facilities in the
area to determine the existence of any above or below ground utilities which may
have an effect on drainage design.
1.3 Geotechnical Investigation
ENGINEER will coordinate the performance of a geotechnical investigation to
determine the hydraulic conductivity of the soil. The geotechnical investigation will
include up to two(2) hydraulic conductivity tests and four(4) standard penetration
tests. ENGINEER will review data upon completion of the testing.
1.4 Permit Coordination
ENGINEER will determine and coordinate with the appropriate permitting agency
and will have at least one coordination meeting with the appropriate agency. During
2
the meeting, the general intent of the drainage improvements will be discussed and
any special conditions that may be present will be determined.
Task 2: Drainage Calculations and Modeling
2.1 Drainage Model
ENGINEER shall develop an ICPR computer model of the existing ground surface
within the right of way area based on elevation data from a topographic survey.
Based on the elevations and natural flow boundaries, ENGINEER will divide the
study into sub-basins. The computer model will be used to determine the maximum
flood elevation per sub-basin during a 5-year and 25-year design storm. The analysis
provided will determine whether the system meets minimum criteria and provide a
cost effective recommendation for improvements.
2.2 Drainage Calculations
Using the analysis of geotechnical results, drainage calculations will be used to
determine the amount of drainage (exfiltration trench) required per sub basin. The
analysis to be performed will examine pre-development versus post-development
conditions that will result in a net increase in water quality and a net decrease in
maximum flood stage.
Task 3: Construction Documents Preparation
3.1 60% Drawings
ENGINEER will prepare and submit required sets of drawings to the CITY. These
drawings will consist of existing conditions and 60%design for review by the CITY
and Regulatory Agencies. Conceptual design will include drainage improvements
