1. Make a seat. ‘‘One small thing a person can do for your city is build an attractive  bench  and place it where it’s needed. There is an urban-seating deficit all over the world and some of my favorite cities are those where people frequently build their own street seats. Here are bunch of examples http://www.streetseats.org/ we once catalogued in New York City’’. – Mike Lydon, “seats inspirer” says. Check the website www.streetseats.org. As silly  as it sounds, the opportunity to sit down is one of the great joys, if not necessities, of urban living. Urban cities all over the world fail to provide enough places for people to rest, socialize , or simply watch the world go by.
Here is another project worthy of attention. "The Street Plans Collaborative," is designed to plan and decorate parks and other places to help people have a comfortable and convenient way to recover themselves after hard-working weekdays http://www.street-plans.com/.
2. Bicycle routes for every place. Every city or town where you live deserves its own cycling routes  with special highlighted zones for cyclists. “Street Plans” organisation has been making really great eco-projects since 2009 and they have a lot of great ideas, including improvement of bicycle lanes . To best illustrate possible and desired physical transformations, Street Plans developed before and after plans, sections, and photosimulation renderings  to communicate desired outcomes . Complimenting the physical design solutions are a variety of infographics, case studies, and best practice descriptions.
The guide will be used to educate the St. Louis region’s citizens, planning professionals, and political leaders. It will also be used to advocate for a more economically prosperous and equitable region, one that focuses on the creation of streets designed for everyone (See https://www.street-plans.com as an example).
3. Create a little free library. Libraries may change and evolve , but the pleasure and joy of reading a book remains. In Dallas, the Little Free Libraries/Libros Libres project http://lfldallas.org/ helped construct and decorate makeshift  shelves positioned across the community. All libraries operate under the guiding principle  of "Take a book, leave a book," and are publicly accessible, and free. We actually also have such libraries in Russia, but they need more support and collaboration with the local people. Inspired  by the wider Little Free Libraries movement https://littlefreelibrary.org/ - it’s creating a real-life literary community on city streets.
4. Plant a tree, or better yet plant a community garden. Shade , serenity , sustainability  – trees add so much to the urban landscape  and ask so little. Many cities give away free trees and planting services. https://www.nycgovparks.
