Rancho Palos Verdes City Council
   

TO: HONORABLE MAYOR AND MEMBERS OF CITY COUNCIL

FROM: DIRECTOR OF PUBLIC WORKS

DATE: AUGUST 19, 2003

SUBJECT: STORM DRAIN SYSTEM MASTER PLAN STUDY UPDATE – AWARD OF PROFESSIONAL SERVICES AGREEMENT

Staff Coordinator: Glen W.C. Kau, Sr. Engineer

RECOMMENDATION:

  1. Authorize the Mayor and the City Clerk to execute a Professional Services Agreement for the Storm Drain System Master Plan Study Update with AKM Consulting Engineers, for the not-to-exceed amount of $40,164.
  2. Authorize Staff to expend additional funds of $2000 for additional services related to the Storm Drain Master Plan Study Update, for a total authorization of $42,164.

BACKGROUND:

A city-wide study (study) of the storm drain system was conducted in 1998 through services provided by AKM Consulting Engineers (AKM). This study identified existing facilities, evaluated the capacities and conditions of the existing storm drains within the City, identified drainage deficiencies, evaluated alternate solutions, and developed/suggested recommendations in the form of a prioritized list of improvement projects with associated construction costs. The study included approximately 75% of City-owned storm drains, as well as pertinent Los Angeles County owned facilities, and a few private storm drain systems. Prior to this study, no master plan of City drainage facilities had ever been completed, and the Los Angeles County Department of Public Works (LACDPW) had been the governing storm drain agency for the area until City incorporation in 1973. Most of the facilities were constructed prior to 1973 while under LACDPW jurisdiction, and are constructed of corrugated metal pipe (CMP) which is approaching the end of its useful service life.

DISCUSSION:

An update to the 1998 study is required, as well as additional studies to supplement the 1998 report. This additional information will provide the necessary detail to better understand the needs of the City’s storm drain system.

The scope of work includes for:

  • Field Inspection of several critical storm drains facilities that were not inspected in the 1998 Storm Drain Master Plan Study
  • Investigation of bluff drainage in the reach from Long Point to the landslide area that was not a part of the 1998 Storm Drain Master Plan Study
  • An update of the estimated costs for rehabilitation (includes for design & construction)
  • An update to the hydrology modeling
  • Updates and Revisions to the System Drainage Maps
  • Provides updates to the collected database information of the 1998 Study and insures the data to be GIS compatible

AKM performed the 1998 Storm Drain Master Plan Study. They are very familiar with the components of the storm drain system and having also created the hydraulic model for the storm drain system, AKM has intimate knowledge of the system and the database. Because of these circumstances, the updates would simply be additions/updates to the existing database and corresponding GIS information. The storm drain system GIS database would be configured to be placed onto the developing GIS system, in a similar manner as the Sewer System database.

Based on discussion from the previous sections, staff recommends that the Council authorize the Mayor and the City Clerk to execute a Professional Services Agreement for the Storm Drain System Master Plan study update with AKM Consulting Engineers, for the not-to-exceed amount of $40,164. It is also recommended that Staff be authorized to expend additional funds of $2,000 (~5%) for additional services related to the Sewer Master Plan study, for a total authorization of $42,164. AKM Consulting Engineer’s data review and database assembly approach seemed most progressive, and when verified during final database review, could result in cost savings to the City during the Capital Improvement Program development (CIP) based on recommended rehabilitation method.

As part of scope for the update, all tasks will be performed as pertains to the areas previously mentioned. The fee breakdown and proposed completion time for AKM Consulting Engineers, along with the associated project scope and have been listed by task and are as follows:

  • Review of Existing Records (Task 1) $2,624 (1 week)
  • Updating Hydrology (Task 2) $5,892 (2 weeks)
  • Field Inspection (Task 3) $5,992 (2 week)
  • Formulate Solutions (Task 4) $2,892 (1 week)
  • Update & Revise System Maps (Task 5) $9,088 (2 weeks)
  • Prepare Updated Report (Task 6) $11,216 (3 weeks)

Expenses $2,500


Total: $40,164 (11 weeks)

(~3 months)

CONCLUSION:

Adopting the staff recommendation will award a professional services agreement to AKM Consulting Engineers, for the preparation of a Storm Drain System Master Plan Study Update/Supplement. This study will be used to update the existing storm drain system database and maps, and help staff understand the City’s storm drain deficiencies.

FISCAL IMPACT:

Adequate funds are budgeted in the FY2003-04 Capital Improvement Program for the recommended actions. The recommended funding source for this project is with the General Fund.

Respectfully Submitted,
