Trinity Shores/FP-DR010830 (2) DEVELOPMENT REVIEW C ENGINEERING COMI [EI TS ITEM: Trinity Shores, Lots 1-19, Final Plat, to allow the platting of 19 single-family lots and two common areas on approximately 7.31 acres of property located along the south side of Sandy Lake Road, west of the Trinity River, at the request of Hobart Development, Inc. DRC D,4TE: August 30, 2001 and September 6, 2001 CONTA CT: Kenneth M. Gri.~n, P.E., Director of Engineering (972-304-36 79) COMMENT STATUS: ,/PRELIMINARY 1. Minimum finish floor should be shown for all lots a minimum of two-feet above the existing floodplain or one-foot above the ultimate floodplain, whichever is higher. 2. Show the right-of-way that was previously purchased by the City with the volume and page number. 3. The proposed inlet to the west of your street connection to Sandy Lake Road is a low point inlet and cannot be relocated. This may affect the location of your street connection to Sandy Lake Road as it appears to have inadequate space for the street and the curb return in additional to the transition to the low point inlet. 4. Based on existing contours, the area to your east, labeled as the Harrington site, drains onto your site. You should make adequate accommodations for that drainage. Based on your grading plan provided in April, it appears that you are raising the elevation of your property approximately 6 feet without taking into consideration the property to the east being able to drain through your property. This will create a situation of standing stagnate water on the property to the east. 5. An off-site easement will be required for the continuation of your storm drain system between lots 11 and 12. 6. The drainage easement that contains the floodplain on lot 11 should be dimensioned. 7. Some type of on-site drainage system will be required for lots 6, 7, 8, 9 and potentially 10 and 11 to handle the on-site water. You are proposing those lots to drain west and south and yet there is no place for those lots to drain with the current development around them. The plans for Eagle Point show that lot 28 also drains north and you are draining lot 8 south. Again, the water will not drain.
