Bruhat Bengaluru Mahanagara Palike [BBMP] — Axing of trees

We are resident owners of Sobha Ruby apartment Nagasandra Bengaluru 560073.

Our apartment has a site of about 3 acres which belonged to our apartment developer by name Sobha Developers limited.(The developers Sobha Developers limited will be addressed as SDL henceforth) SDL relinquished the 3 acre site to Government body duly signed by executive engineer of BDA west Division Bengaluru.

But suddenly the apartment society is calling all the members for a cleaning drive of the site stating SDL is building a bridge on the site as the site and our apartment is separated by Rajakaluvai.

Is it correct? Can we axe trees in 3acres land without permission from Government body.

So I request he BBMP/BDA to clarify whether they have given permission to axe the trees clean up site and build a bridge over or on the Rajakaluvai .

Best regards
