Philadelphia was created in the 17th century, following the plan by [[William Penn]]'s surveyor [[Thomas Holme]]. [[Center City, Philadelphia|Center City]] is structured with long, straight streets running nearly due east–west and north–south, forming a grid pattern between the [[Delaware River|Delaware]] and [[Schuylkill River|Schuylkill]] rivers that is aligned with their courses. The original city plan was designed to allow for easy travel and to keep residences separated by open space that would help prevent the spread of fire.<ref name="Philadelphia Squares">{{cite web |url=http://philadelphia.cbslocal.com/2011/02/04/a-guide-to-philadelphias-squares/ |title=A Guide To Philadelphia's 'Squares' |publisher=CBS Philly |date=February 4, 2011 |access-date=April 29, 2015 |author=Daly, Molly |archive-date=February 13, 2011 |archive-url=https://web.archive.org/web/20110213014158/http://philadelphia.cbslocal.com/2011/02/04/a-guide-to-philadelphias-squares/ |url-status=live }}</ref> In keeping with the idea of a "Greene Countrie Towne", and inspired by the many types of trees that grew in the region, Penn named many of the east–west streets for local trees.<ref>Laura Turner Igoe, "[https://philadelphiaencyclopedia.org/archive/trees-2/ Trees] {{Webarchive |url=https://web.archive.org/web/20210208184841/https://philadelphiaencyclopedia.org/archive/trees-2/ |date=February 8, 2021 }}", ''The Encyclopedia of Greater Philadelphia''; accessed 2021.01.29.</ref> Penn planned the creation of five public parks in the city which were renamed in 1824.<ref name="Philadelphia Squares" /> Centre Square was renamed [[Penn Square, Philadelphia|Penn Square]];<ref>[https://www.philadelphiabuildings.org/pab/app/pj_display.cfm/20977 "Philadelphia City Hall"] {{Webarchive |url=https://web.archive.org/web/20171111041648/https://www.philadelphiabuildings.org/pab/app/pj_display.cfm/20977 |date=November 11, 2017 }}.

Philadelphia's neighborhoods are divided into six large sections that surround Center City: [[North Philadelphia]], [[Northeast Philadelphia]], [[South Philadelphia]], [[Southwest Philadelphia]], [[West Philadelphia]], and [[Northwest Philadelphia]]. The city's geographic boundaries have been largely unchanged since these neighborhoods were consolidated in 1854. However, each of these large areas contains numerous neighborhoods, some of whose boundaries derive from the boroughs, townships, and other communities that constituted [[Philadelphia County, Pennsylvania|Pennsylvania County]] before their inclusion within the city.<ref>{{Cite book |title=Insight Guides: Philadelphia and Surroundings |page=58 }}</ref>

The [[City Planning Commission (Philadelphia)|City Planning Commission]], tasked with guiding growth and development of the city, has divided the city into 18 planning districts as part of the Philadelphia2035 physical development plan.<ref>{{cite web |url=http://phila2035.org/home-page/about/ |title=About Philadelphia2035 |access-date=April 29, 2015 |archive-date=May 3, 2015 |archive-url=https://web.archive.org/web/20150503011928/http://phila2035.org/home-page/about/ |url-status=dead }}</ref><ref>{{cite web |url=http://www.phila.gov/CityPlanning/plans/Pages/Phila2035.aspx |title=Philadelphia 2035: The Comprehensive Plan |publisher=Philadelphia City Planning Commission |access-date=April 29, 2015 |archive-date=March 31, 2015 |archive-url=https://web.archive.org/web/20150331055720/http://www.phila.gov/CityPlanning/plans/Pages/Phila2035.aspx |url-status=live }}</ref> Much of the city's 1980 zoning code was overhauled from 2007 to 2012 as part of a joint effort between former mayors [[John F. Street]] and [[Michael Nutter]]. The zoning changes were intended to rectify incorrect zoning maps to facilitate future community development, as the city forecasts an additional 100,000 residents and 40,000 jobs will be added by 2035.

The [[Philadelphia Housing Authority]] (PHA) is the largest landlord in Pennsylvania. Established in 1937, the PHA is the nation's fourth-largest housing authority, serving about 81,000 people with affordable housing, while employing 1,400 on a budget of $371&nbsp;million.<ref name="PHA">{{cite web |url=http://www.pha.phila.gov/pha-news/pha-fast-facts.aspx |title=Philadelphia Housing Authority |publisher=Pha.phila.gov |access-date=December 24, 2013 |archive-date=January 6, 2014 |archive-url=https://web.archive.org/web/20140106183506/http://pha.phila.gov/pha-news/pha-fast-facts.aspx |url-status=live }}</ref> The [[Philadelphia Parking Authority]] is responsible for ensuring adequate parking for city residents, businesses, and visitors.<ref>{{cite web |url=http://philapark.org/about-ppa/history/ |archive-url=https://web.archive.org/web/20120126033326/http://philapark.org/about-ppa/history/ |url-status=dead |archive-date=January 26, 2012 |title=Philadelphia Parking Authority: History |publisher=Philapark.org |access-date=December 24, 2013 }}</ref>
