Regular fly tipping outside our back gate on Albert Park Place

Dear BCC I'm so fed up with people fly tipping at the back of 85 Ashley road... Albert park place. Yesterday I needed to park our car in the back, a discarded mattress was blocking the gates and I couldn't move it myself... I have a painful shoulder injury. I had to drive over it when I left which could have damaged our car. The street signs have been stolen from the corner of Norrisville rd and the Albert Park place sign at the back of 85 Ashley road Montpelier BS6 5NR. There are often drug dealers in this area and we had our bikes stolen from the back a couple of years ago. Our landlords places for people tell us we have to put our bikes in the back lockup but I don't want addicts/thieves to see us going in the back with our bike until there is a CCTV camera at the back of the building. People also block our back gates not only with fly tipping but also badly parked cars. The double yellow lines need re. Please will you contact me regarding this issues asap. Warm regards Jade Laing-Strachan
