applejack, Hawley is one of the streets that was heavily affected by the 1986 fire. There were many homes completely lost on it, and much bigger homes later built in their places as many senior-citizen owners were uninsured or grossly under-insured at the time and had to sell their (often canyon-rim) lots. The house you are purchasing has a westerly-facing premium canyon lot of 1/2 AC and there are only just so many of these. Your lot will have endless possibilities. I do not think you will regret this purchase.
Your listing states your home was built in 1970 and I did not look at any photos of it but I have no doubt that it is a very nice well-built contemporary home. There is NO WAY you can obtain this type of property with THIS view in any of the North County areas you listed. Do you know if this particular home was affected by the fire (i.e. partially destroyed and rebuilt)? If so, then much of the structure is only 20-22 years old as opposed to 40 years old.
In addition, you will be avoiding having to pay substantial Mello-Roos bonds (an addition to your property tax) for 25-40 years in all of the areas you mentioned above, by purchasing this very well-located Normal Heights property.
Congratulations on your new home purchase and addition to your family!
