A Survey on the Preferences of Registered Voter Households in the Unincorporated Area of Bloomington, CA Regarding Warehouse Development

IE2030 - Thursday, October 19, 2017

Introduction

Bloomington, California is an unincorporated area of San Bernardino County located just southwest of Rialto, California. According to the 2010 census, Bloomington has an estimated population of 24,000 people, and is represented by Fifth District San Bernardino County Supervisor, Josie Gonzales. Supervisor Gonzales is advised on Bloomington related policy issues by the Bloomington Municipal Advisory Council (Bloomington MAC), whom she appoints.

 

Currently, Bloomington’s land zoning consists of a variety of uses, including agricultural, residential and commercial uses. In 2016, the San Bernardino County Supervisors voted yes to build a 680,000 square foot warehouse near Zimmerman Elementary School and are now considering building more warehouses in Bloomington -- near Bloomington High School, Slover High School, and next to residential properties. These recent development decisions, accompanied with an aggressive approach by commercial development firms to purchase agriculture and residential property, has led to the community’s desire to measure public opinion regarding warehouse development near schools, residential property, and as an economic development strategy in Bloomington.

 

In an effort to provide input from the individuals most directly impacted by the San Bernardino County Supervisors pending land zoning changes -- allowing the placement of warehouse development next to schools and residential areas -- IE2030 conducted a survey that detailed a random sampling method of the affected population preferences. Due to the political nature of the pending decisions, the survey was designed intentionally short and decisive to maximize full participation and avoid any self-selection that would influence the survey results.

 

The survey employed a sampling framework to obtain a random sample of households in Bloomington with at least one registered voter. To achieve the highest response rate possible, the current County of San Bernardino Registrar of Voters data was queried to identify voters eligible. Duplicate lines and home addresses were removed to ensure each household was represented once within the sample. The survey was conducted through a self-administered interactive voice response (IVR) system. All outbound calls that resulted in a live answer were included in the sample. Outbound calls not resulting in a live answer were cycled back into the system to be retired the following day. This process was administered for two consecutive days following the start of the survey. The survey was administered for a total of three consecutive days. The objective was to call back the numbers that were not live answers to increase the survey respondents. There were 512 households in the sample that were called. There were 146 live answers on day one, 44 live answers on day two and 19 live answers on day three. On average, there were 62.6 total respondents per question. The survey included three questions about warehouse preferences.

Questionnaire Design

Due to the nature of this survey, which included a politically sensitive question about recent San Bernardino County Supervisor decisions, three general questions avoiding the use of leading words and biases were posed. The questionnaire is provided in its entirety below:
