I'd also recommend you change the structure of your procedure names:

it's considered as bad practice to start your stored procedures with sp_ since SQL server will try to find those sp's in master DB first (unless the proc is fully qualified or in a schema other than dbo).

This may cause unintended results. If you ever decide to name a proc "sp_addtype" that is used to add a specific type of area you'll see what I mean... 😉
