Environmental Issues


As a Tree City, Forest Hills and its residents are conscious of the need to protect our environment. The borough is proud to be a leader in this area with its tree program, recognized by the Arbor Day Foundation.

Links on this page are dedicated to ways in which the borough continues to promote environmental awareness among its citizens. Information is also provided on the various programs offered by the borough. Please click a link for further information or to read the article shown. Chapters from the borough’s code of ordinances related to each section heading are included at the bottom of the list (Note: see the Code of Ordinances page for full information and updates or amendments). Further information and updates may also be found in recent issues of the borough’s newsletter, the Tree City Times.

Air Quality

The Allegheny County Health Department (ACHD) measures air quality every day using monitors throughout the County, and the readings of those monitors are classified on an Air Quality Index (AQI). If the AQI is forecasted to be over 100 on a given day, ACHD issues an Air Quality Watch. If the AQI is measured at over 100, ACHD issues an Air Quality Warning. This information is then communicated over the Allegheny Alerts system.

If you would like to receive alerts go to www.alleghenycounty.us/alerts and enter your contact information. When an alert is sent on a topic you’ve chosen, you’ll receive it on the devices you’ve selected. Get an email at work, text on your cell and call at home – as many or few as you want. There’s even an app for it. You can add, delete and change your devices and topics any time. It’s all up to you.

To understand more about our air quality and the index check out the brochure here.
