Executive Summary

On September 19, 2006, the City Council awarded a contract for engineering services contract to Costello, Inc.  The contract provided for a comprehensive drainage study of the Sugar Mill Drainage System.

 

Previous studies of Ditch A-22 had revealed inadequacies in the Sugar Mill Drainage System.   Both Sugar Mill residents as well as Public Works staff have reported severe ponding levels at some locations within Sugar Mill subdivisions during the occurrence of past rain events.  A few houses in Sugar Mill also took in water during the occurrence of Tropical Storm Allison in 2001.

 

In order to address the above issues and to better identify the problem, the City performed a comprehensive study of the Sugar Mill Drainage System.  This study was funded via the City’s CIP program (DR0606).  The study scope included analyzing all sections of the Sugar Mill Drainage System.  During the course of this study, input from the Sugar Mill residents and HOA representatives were solicited to identify problem areas.

 

The main objectives of this study  were to: 

  • Identify deficiencies in the Sugar Mill internal drainage system (streets and underground infrastructure)
  • Propose relief projects to improve the drainage system
  • Incorporate proposed improvements into the City’s Drainage CIP

 

This comprehensive study was completed recently.  Engineering staff has reviewed the findings and recommendations identified in this study.  These recommended improvements were separated into logical phases.  Each phase was then compared to the ranking criteria developed as part of the updated Master Drainage Plan to establish a priority order possible inclusion in the City’s CIP program. Staff attended the Sugar Mill HOA  Board of Directors meeting on October 15th and gave them an update on the status of plans for the construction of a new restrictor, as well as the findings and recommendations of the Sugar Mill Drainage Analysis. The Board was pleased with the City’s progress and plans to attend this workshop meeting.

 

Engineering staff will present an overview of the study, priority order for improvements and discuss the proposed improvements and phasing plan.  The findings of this study have also been reviewed by the Sugar Mill HOA consulting engineer (Dodson & Associates, Inc.).
