LLOYD REGISTERED CIVIL ENGINEER 3538 REGISTERED LAND SURVEYOR 944 TELEPHONE JO 2-4112 1 B 3 S ZOTHSTREET VERO BEACH, FLORIDA 32960 Pursuant to attached letter, I have discussed the Street Drainage situation with Mr. Mark Baggett, Engineer for the project. He will comply with criteria established by this office. I have suggested that they proceed with filling the ditches and shoulders to make the streets safe and passable, prior to the completion of the drainage plan. Mr. Baggett and I have a meeting scheduled for Monday at which time we hope to resolve the maximum swale depth that will be permitted. It is anticipated that this figure will be between 18 and 24 inches below the edge of the pave- ment. Yours very truly, LLOYD AND ASSOC ES By: Robert F. Lloyd, E. RFL/fhe W/enc .

S. #1 Vero Beach, Florida 32960 ROBERT F. LLOYD REGISTERED CIVIL ENGINEER 3538 REGISTERED LAND SURVEYOR 944 TELEPHONE JO Z-4111 1035 ZOTH STREET VERO BEACH, FLORIDA 92960 Attention: Mr. Mark Baggett, P. E. Manager, Engineering Dear Mr. Baggett: I am in receipt of your sketch forwarded to the City of Seb- astian on October 31, 1975. I would first like to comment on our meeting with Bob Blem and others of your organization on our recent field trip to the project. As you will recall, I insisted that the criteria for the renovation of these ditches was as follows:- 1. ollows:- 1. That adequate shoulders be provided for safe driving. 2. That the slope be flat enough so they can be maintained with equipment, mowed, etc. 3. That adequate drainage be provided. 4. That the swales be shallow enough that they will be swales and not ditches. On several of your cross sections you indicate that the back - slope of the ditch is layed over on private property to which we have no objections provided we have an easement for the maintenance of these slopes after they are accepted by the City. As you can appreciate, the City without such right of easement would have no drainage if the property owner elected to fill his property and the swale.

There are, of course, alternate solutions. 1) We could flatten out the ditch grades to as little as .005%, to lessen the ditch depths, then drop rapidly the last few feet. 2) The proposed shoulders of 8' could be reduced to 4' or 6' to avoid excavation beyond the right-of-way. 3) If you approve, we could utilize the existing road pipes as in- verted siphons. We would appreciate it if you would take this up with your City Engineer and advise us of approval. Wneth ely, F. Miller, P. E.
