How to create a model to select a street centerline using interactive drawing tool?

[SonaSunny]

I am trying to create a model using model builder that will select all the parcels that are within 50 ft from a desired street centerline . I want to use a interactive drawing tool to select the street of interest and then run the tool. I created a feature set variable for that purpose and made it a model parameter.

when I run the tool, I am able to interactively draw a line over my street of interest but the tool is selecting all the adjacent streets also that intersect that line that I drew . As a result the final table has lot more parcels selected. Can someone help me to fix this? When I draw a line interactively over a street I want only that street to be selected.
