I. INTRODUCTION

1.1 General

The LA approach to projects of this nature combines the strong technical capabilities of
the project team with a "common sense attitude" toward providing the most technically feasible
and cost effective solution for the City of Sterling. Our approach to similar projects has been
utilized effectively over the last five years in support of the City of Fort Collins Stormwater
Utility and over nearly the last two years in support of the City of Greeley Public Works
Department.
Our work for the City of Fort Collins has typically involved the evaluation of existing
storm water problems and the preparation of storm water management plans, including numerous
updates to the existing master drainage plans within the City of Fort Collins. Our work for the
City of Greeley has focussed on reviewing and updating the 1974 Comprehensive Drainage Plan
for Greeley, including a city-wide drainage evaluation and hydraulic design of runoff conveyance
and flood protection measures. This work has included the prioritization of drainage and flood
control improvements on a city-wide basis, including an economic evaluation of the proposed
improvements. Consequently, LA is uniquely qualified to provide engineering services in
support of this project for the City of Sterling; the experience of LA in development of master
drainage plans and storm water management plans will serve the Sterling Public Works
Department in the timely and efficient completion of the Flood Control and Drainage Project
Prioritization Analyses.
The project team introduced in the following chapters has been assembled to offer the
City of Sterling professional expertise and commitment. We take pride in our ability to
contribute to the successful management of storm water in the northern Colorado communities
in which we live and work; we hope to offer this intangible element of project success to the
Flood Control and Drainage Project Prioritization Analyses at Sterling, Colorado and Vicinity

1.2 Project Overview and Understanding

The City of Sterling is a thriving, primarily agricultural community located in
northeastern Colorado, approximately 115 miles east of Fort Collins. Major drainage and
flooding activity within the City is impacted by the South Plate River, Sand Creek, overflows
from Pawnee Creek, and the Pioneer Ditch Outfall. It is our understanding that the issues
associated with flooding caused by the South Plate River are beyond the scope of this project
