c) Conduct a general review of the mapped street systems, noting overall existing right-of-way widths,
clearances between rights-of-way and building structures, and potential future encroachments and/or demolition
with respect to right-of-way widening.
d) Study the present street system with respect to usage by passenger and commercial vehicles.
10. Upon review of all existing grades and street systems, the Consultant shall determine the impact that the raising
and/or lowering of all streets to legal grade and/or the widening of rights-of-way will have upon the abutting properties and

11. Upon evaluation of all data thus obtained, the Consultant shall determine, on the basis of feasibility, economic
impact and preservation of the character of the neighborhood, those areas where retention of existing grades and street
systems is both necessary and desirable.
12. The Consultant shall then design new proposed legal grades as necessary.
13. The design of all proposed legal grades shall be performed in accordance with procedures, concepts and criteria as
required by the Department.
