DPD’s Communications and Outreach Division created this guide as a supplement to AP Style and to address department-related style questions. Please consult this when producing copy in order to ensure stylistic consistency across DPD.

Acronyms 

Avoid using on first reference if the audience may not be familiar with the acronym. However, place the acronym in parentheses immediately following the first reference. 

Example: The Department of Planning and Development (DPD) will … 
 
Alderman 

When writing out an alderman or alderwoman’s full name and title on first reference, abbreviate as Ald. before the name. Place the ward in parentheses. 

Example: Ald. Julia Ramirez (12th) 

Write out as “alderman” or “alderwoman” when not preceding a name. Use “aldermen” as the plural form. 
 
City

Examples: 

Responses to the City’s Request for Proposals …

Capitalize as City Council when the two words are together. Lower-case as council when the word stands alone. 
 
Commissions/Committees 

Chicago Plan Commission 
Commission on Chicago Landmarks 
Community Development Commission 
Zoning Board of Appeals 
Chicago Development Fund 

For committee names, place “Commitee” last. (Finance Committee, Workforce Development Committee) 
 
Community areas 

The City’s 77 officially defined community areas should take precedence over any neighborhood names that are not part of that official list. For instance, West Town should be used in reference to a business located in Wicker Park. 

When referring to any of the 77, always use “community area” in lieu of “neighborhood.” 
 
Dates 

For dates and years, use figures. Do not use st, nd, rd, or th with dates, and use Arabic figures. Always capitalize months. Spell out the month unless it is used with a date. When used with a date, abbreviate only the following months: Jan., Feb., Aug., Sept., Oct., Nov. and Dec.

For all figures that contain decimal points, round to the nearest tenth. 

For decimals that are less than 1, do not include a 0 before the decimal point. (Example: .7)

Always write out on first reference. Typically, “Chicago” can be omitted from the name. DPD on subsequent references. 
 
Email addresses 

Do not capitalize any letters in email addresses. 
 
First- and second-person language 

Generally, avoid first person references, such as “our city” or “we welcome your comments,” since these terms can be alienating to people who are not familiar with DPD or the City. Stick to the third person. Exceptions do exist, such as a social media post seeking community feedback. (“How do you envision Milwaukee Avenue in the future? Attend a community meeting ... “) 
 
Headlines 

Capitalize all words in headlines that are more than four letters long. 
 
Inclusive language

One word. (not La Salle) 
 
“L” 

Use double quotation marks when referring to the CTA rail system. 
 
Millions and billions of dollars 

“Million” and “billion” should be written out in all standard copy. 

Example: City Council approved $5 million in TIF assistance for an affordable housing development in North Lawndale. 

In instances such as headlines and break-out boxes, where more concise text is ideal, “million” and “billion” can be abbreviated to “M” or “B.” 

Example: City Council approves $5M in TIF for North Lawndale affordable housing project 
 
Oxford comma 

Use the Oxford comma after the penultimate item in a list of three or more items.
