List Creation Through Feature

Hi,

I want to create a list through Featute.When that Featute will get activated ,List should be created. I am able to create list when I am hard coding the site URL.But Whenever I am writing site url as

public override void FeatureActivated(SPFeatureReceiverProperties properties)
        {
            try
            {
                SPSecurity.RunWithElevatedPrivileges(delegate()
                {
                    using (SPSite site = new SPSite(((SPWeb)properties.Feature.Parent).Url))                {
