​Block Parties

Neighborhood Block Party

Hosting a party with your neighbors is great way to connect with your neighbors and build a united neighborhood! Celebrate National Night Out on the first Tuesday in August or National Good Neighbor Day on September 28. 


Closing a residential street within a subdivision requires a traffic control permit.  Arterial and collector streets are not permitted to be closed for block parties. There is no cost for this permit. Permits must be submitted at least five days prior to the event and all affected residents must be notified. A link to the permit is on the right hand side of this page. Traffic control permits can be submitted online.

An alcohol permit is required if you choose to have alcohol at a party that will take place on city sidewalks, streets or at parks. Only 3.2% alcohol may be consumed. The alcohol permit takes 30 days to process and requires a refundable deposit of $50. If you would like to apply, please read the instructions, complete the application and submit it with other applicable documents to the City Clerk's Office, 9500 Civic Center Drive. A link to the permit is located on the right hand side of this page. 


New this Year!

Reserve a block party trailer with supplies, such as games, tables, chairs and coolers!  The city will have a 'Block Party Trailer' available starting summer 2018 with supplies that Thornton residents can reserve on a first-come, first-served basis. Check out the Block Party Trailer flyer link under Block Party Resources.  

Other things to consider for your block party

  • Please be considerate of neighbors who are not at the party. Amplified sound is not permitted in residential areas. The Thornton Police Department will enforce the City Code (Section 38-441), which states that it is unlawful for any person or entity to knowingly, willfully or recklessly make, permit, or cause any sound that is an unreasonable noise.  If you have a question about noise or are being affected by excessive or unreasonable noise, please call the Police Dispatch Center at 720-977-5150.
  • To request Thornton police or firefighters visit your National Night Out event, contact Officer Matt Barnes at 720-977-5024.
