Example ACL

I need to add a VLAN to our layer 3 switch. It's a Dell 4000 series. I need this VLAN to not be routed to the other VLANs nor them to it. But I need it to have an Ip address for clients on this VLAN to receive an Ip via our DHCP server. VLAN routing is turned on for the other VLANS. Can someone give me an example what I'd need for an ACL to do this? Say the new VLAN is VLAN 100 and we have VLANs 10, 20 , 30 etc.
