SUMMARY:
Consider a request to replat three lots into one for the purpose of new development. The property is zoned Heavy Industry (HI). The property is generally located on the east side of Camden Drive south of E. Jefferson Street.
COMMENTS:
The primary purpose of the replat is to combine Lots 46, 47 and 48, Block 4 of the Idlewood Heights Addition to accommodate a new development proposal for used auto sales and to establish the lowest floor elevation of the future development that is a minimum of two-feet above the base flood elevation. In addition, a drainage easement will be established on the entire portion of the replat formally known as Lot 46, Block 4 of the Idlewood Heights Addition.
The Engineer has completed the technical revisions as requested by staff. Other than minor technical revisions and final submittal requirements prior to filing, this plat is recommended for conditional approval by the Commission.
Conditional approval of this plat by the Planning & Zoning Commission shall constitute approval subject to conformity with the prescribed conditions, but shall constitute disapproval until such conditions are met.
With the exception of the items listed as conditions of approval, this plat is in substantial compliance with the requirements of the Unified Development Code.
CURRENT PLANNING: Jim Hinderaker (972) 237-8255
M. 1. The proposed Lot 2, Block 4 of the Tiger Auto Addition must be combined with proposed Lot 1, Block 4 of the Tiger Auto Addition to create a single lot totaling 0.491 acres.
M. 2. Revise the Note No. 7 to state, “Lowest floor elevation shall be 2.0 feet above the base flood elevation.”
M. 3. Add base flood elevation to plat.
ENGINEERING/FLOODPLAIN: Brent O’Neal/Chris Agnew, (972) 237-8141
M. 1. City approved grading, drainage, and erosion control plans are required prior to approval of any final plat, earthwork or building permit for the property. Such plans shall include complete plans and profiles of all storm drainage facilities with hydrologic and hydraulic information designed to current standards as provided in the Drainage Design Manual as currently amended. Tie storm drain hydraulics to existing downstream storm drain and extend to upstream properties. Where applicable, drainage from site shall discharge into drainage easement and shall convey flow to stream without causing erosion or flooding (maximum downstream velocity 6 fps). 100-year overflow shall be conveyed to stream in drainage easement;
M. 2. Offsite drainage flows currently drain through the proposed plat. A storm drainage system must be provided to receive and convey these offsite flows through the plat to an acceptable outfall point with a minimum width 15’ drainage easement dedicated on the plat to cover the drainage system;
M. 3. Plat adjoins an unregulated creek. A Hydrology and Hydraulics study will be required to define the fully developed 100-year floodplain on the plat and an appropriate floodplain easement covering the fully developed floodplain limit dedicated on the plat. In place of the study the applicant may use the City estimated fully developed floodplain limit with a 100-year water surface elevation of 449.8 feet msl across the plat adjoining the creek for delineation and floodplain easement dedication;
M. 4. A floodplain development permit shall be required for any development in the 100-year floodplain of the adjoining creek;
M. 5. Finished floor of any structure to be built on the plat should be at least 2 feet above the 100-year flood elevation for the property as shown on the engineer study or the City estimated determination; specify this minimum finish floor elevation on the plat;
M. 6. Illegal filling has occurred on this plat with no corrective action performed by the property owner. As such, the property owner is subject to certain sanctions including but not limited to the floodplain fill being removed below elevation 549.8 msl or an approved fill permit is secured from the City Floodplain Administrator Mazen Kawasmi (972-237-8157) for the plat. We request this replat be pulled from consideration until the plat is brought into compliance with City ordinances and Codes. Below is the email of request from the City Floodplain Administrator requesting this action:
Note to applicant: Some comments below may not pertain to your development. Contact the Development Coordinator for clarification.
Approval of a project by the Planning and Zoning board, and/or City Council, does not release the Building Inspections Permit or Public Works Permit for construction.
It is the developer’s responsibility to confirm with the Planning Department if the property is to be (re-platted, preliminary, and/or final) platted.
It is the developer’s responsibility to submit all required escrow funds for third party drainage review for public improvements prior to construction plan submittal.
It is the developer’s responsibility to confirm the submittal of plans for review to the Engineering Division.
It is the developer’s responsibility to submit all required escrow funds for third party geotechnical and material testing for public improvements that are to be dedicated to the City prior to release of the construction permit.
Final engineering plans released for construction are required prior to the recording of the final plat.
It is the developer’s responsibility to submit any required escrow funds for streets or sidewalks.
A preliminary drainage plan that meets City Code may be required. The plan shall address possible need for detention and provide preliminary storm drain layout and sizing for all lots.
Grading, drainage, and erosion control plans, released for construction are required prior to filing the final plat. Such plans shall include complete plans and profiles of all storm drainage facilities with hydrologic and hydraulic information. Proposed storm drain hydraulics shall tie to existing downstream storm drain hydraulics. Where applicable, drainage from the site shall discharge into a drainage easement and shall convey flow to a stream without causing erosion or flooding. The 100-year overflow shall be conveyed in a drainage easement.
Delineate the fully developed floodplain on plats and drainage plans with flood elevations and minimum finished floor elevations for structures. Floodplains and/or maximum water surface elevation for bodies of water shall be dedicated as drainage right-of-way (ROW) or in a drainage easement upon the plat. Drainage ROW shall be dedicated fee simple to the City of Grand Prairie. Also provide cross sections showing that limits of drainage easement have a maximum 4:1 slope from the streambed. Proposed slopes greater than 4:1 must be supported by an engineered design and will be reviewed on a case-by-case basis by the Engineering Department. Any work within floodplain will require Floodplain Development Permit and, if applicable, FEMA approval.
Delineate any erosion hazard setback upon the plat.
Any future improvements may require investigation of the adequacy of the downstream drainage system to convey increased flows. Construction plans for downstream improvements shall be required if the downstream system is not adequate to convey the increased flows. Proposed flows shall be within drainage easements or ROW’s with no erosive velocities. This may require detention or additional detention or other improvements.
Add a note to preliminary plats:
The subject property is (or, is not) located within the 100 year floodplain per FIRM Panel # _________________, dated _____________________.
Where applicable and prior to construction, submit certification by a professional that site does not have wetlands and other waters of the United States, an investigation showing that site development will not impact wetlands and other waters of the United States, or a permit for proposed activities in wetlands and other waters of the United States.
