Parish Boundaries

If your child does not attend St. Isidore School or Faith Formation please check the boundary below.  If you do not live within the boundary your child is not eligible to play in our program.  Please find the parish whose boundary you live and contact them.  We check boundaries but do not do so immediately due to the high number of registrants.  If you incorrectly register in our program and it is found at a later date you are not within our boundaries your child will not be accepted into our program and could miss registration of the proper program he/she should register.  This is your responsibility.

For an overview map of the boundaries click here Boundary Handout - it is not great but provides a general map of our boundaries.  For a more detailed and interactive map go to Oakland Dioceses Boundary - click on the blue Danville area and zoom in as needed:
