/var/run/renderd/ deleted on reboot

I have everything working now on Ubuntu 15.04 w/ OSM bright, but on each reboot /var/run/renderd is automatically deleted and renderd fails to start as it can't find it's socket directory. I have to manually create this directory each reboot.

Is there a way to do this in the service file? I attempted the following:

[Unit]
Description=Rendering daemon for Openstreetmap tiles

[Service]
User=astump
Type=forking
ExecStart=sudo mkdir /var/run/renderd
ExecStart=sudo chown -R astump /var/run/renderd
ExecStart=/usr/local/bin/renderd -c /usr/local/etc/renderd.conf
ExecStop=/bin/kill -s QUIT $MAINPID

[Install]
WantedBy=multi-user.target

But it still fails to create the /var/run/renderd folder

astump@astump15:~$ sudo systemctl status renderd.service
