3 January 4, 2016 Mr. Jerome Fournier Ascension Parish Planning Commission P.O. Box 1659 Gonzales, La CSRS, INC Perkins Road, Suite 200 Baton Rouge, Louisiana Phone. (225) Fax. (225) RE: C.A.P. SPUD Development Plan Review Mr. Fournier: As the Engineering Review Agency for the Ascension Parish Planning Commission, we have reviewed the Development Plan, Drainage Impact Study, and Traffic Impact Study submitted for the above referenced development for compliance with the Ascension Parish Subdivision Regulations and the Ascension Parish Development Code. Shown below are the comments made to the Consulting Engineer for the project as a result of our review of their submittals, as well as a description of their correction or response made to our comments (shown in bold print). Preliminary Plat 1. The Northern property line abuts a residential zoning/use and is therefore required to have a buffer yard with 7 Class A trees or equivalent. The buffer yard needs to be labeled as such along the northern and western property lines and the label stating a buffer yard is not required needs to be removed. Consultant appears to have addressed buffer yard requirements, however, this will be further reviewed during the building permit review process. 2. Label trees as Class A Trees on Landscape Plan. This has been added to the development plan. 3. Trees along relocated bayou should be shown in islands adjacent to driveway as DPW will not want trees too close along the edge of the relocated waterway. Also, it looks like there will be catch basins near the currently shown tree locations. Consultant added labels to indicate existing characteristics. 4. Parking lot tree count appears to be 10 and not the required Label fence on the Landscape Plan. This has been added to the development plan. 6. Show anticipated trail section on Landscape Plan. Ensure the trail material is noted. This has been added to the development plan. 7. Parking spaces are required to be a minimum of 200 sq. ft. except where they are adjacent to outer perimeter or interior landscaped areas. In these areas the depth may be reduced by two feet making

4 the minimum required area of each parking spot 180 sq. ft. This has been updated on the development plan. 8. Toward is misspelled under PROJECT DESCRIPTION on Sheet. A 1.0. This has been corrected on the development plan. 9. Applicant shall coordinate with Ascension Parish Utilities Department on final location of Sewer Treatment Plant. The plant should also have perimeter fence. This has been added to the development plan. 10. Show all existing and proposed drainage servitudes. Ensure any servitudes that are to be revoked are labeled as such. This has been added to the development plan. 11. Depict and note the proposed drainage servitude of Bayou Goudine. Ensure adequate widths are provided from the top banks of the ditch per Section of the Ascension Parish Subdivision Regulations. In addition, it appears that a portion of the parking lot will fall within the drainage servitude. A Hold Harmless agreement will be required from DPW to allow parking within the drainage servitude after a detailed design is completed. This has been added to the development plan. The consultant stated a Hold Harmless agreement will be submitted upon design approval. 12. Note the existing land characteristics on the survey map. This has been added to the development plan. 13. The SPUD Development Checklist requires an aerial photograph to a scale of 1 = 200 taken within 2 years of the application. Please include this within the plans. This has been added to the development plan. 14. Provide a note stating, There are no existing curves on public streets within one-fourth (1/4) mile of the proposed entrance. This has been added to the development plan. 15. Depict the two proposed 5 x7 box culverts under the SPUD entrance on sheet A 1.0. This has been added to the development plan. 16. Note that this site is subject to traffic impact fees and confirm whether or not this site is subject to sewer development fees. Coordinate with Carl Ladmirault from Ascension Parish to determine sewer development fee requirements. This has been added to the development plan. 17. Under Buffer yard Requirements on the landscaping plan, add line for 422 north property line calculating required number of Class A trees (7). This has been added to the development plan. 18. Label the 55 drainage servitude of Bayou Goudine with arrows pointing to the specific lines. This has been added to the development plan.

5 19. Label or otherwise more clearly delineate the top bank lines of Bayou Goudine. This has been added to the development plan. 20. Provide arrows pointing to the 25 front building line. This has been added to the development plan. 21. The parking space count seems to be incorrect. Please recount and revise circled numbers and update parking total note as necessary. This has been updated on the development plan. 22. The most recent submission did not include the previous version of the Boundary and Topo Survey map, and a comment response suggested this was revised to the Area to be Rezoned map. The General Notes section on the previous survey map needs to be included with the submittal as it contained required information per the Ascension Parish SPUD Development Plan Checklist. Please confirm whether the Boundary and Topo Survey map is to be a separate document or if this has been revised and replaced with the Area to be Rezoned map. If it is intended to replace the previous survey map, the General Notes section needs to be re-added. This has been updated on the development plan. Drainage Study 1. The HEC-RAS models show Longwood Avenue is overtopped at ~16.5. The topographic survey suggests this roadway is higher than this elevation. Provide evidence from the Longwood HOA or DPW showing this road gets overtopped with water in 10-year events, otherwise extend the HEC-RAS models to show water is contained within the banks of the Bayou and adjust road elevations to more accurately reflect the survey map elevations. Additionally, if the roadway is not overtopped during a 10-year event, add ineffective areas to the upstream and downstream areas around the two 5 x7 box culverts. Consultant noted Longwood Avenue elevation as 18.5 and revised HEC-RAS model accordingly. 2. Label station numbers on the HEC-RAS model graphs. This has been added to the DIS. 3. The existing and proposed conditions show offsite water from Longwood Subdivision to the North drains across this property. Although this is a conceptual design, only one inlet is shown along the northern property line which may be inadequate. This design will need to be further reviewed when more detailed plans are submitted. Consultant acknowledged the design will be further reviewed when detailed construction plans are submitted. 4. Both pre and post HEC-RAS models show Lottie Henderson Rd. at a lower elevation than is suggested by the survey map. Revise the deck/roadway height to more accurately reflect the survey map elevations and extend the HEC-RAS models to show water is contained within the banks of the Bayou. In addition, update the Pond Pack model as necessary. Resubmit an electronic copy of the revised HEC- RAS model for our review. Consultant revised roadway height and updated DIS accordingly.

Sight Distance Evaluation: Sight distance was evaluated at the current condition and concluded that sight distance will cause no traffic operational problems for this proposed development. The following intersections were studied with the following conclusions: LA 73 at Site Drive #1 (Right In/Right Out): The eastbound approach is anticipated to operate at a level of service (LOS) of B during both AM and PM peak periods. A right-turn lane was not warranted during the AM or PM peak hours. No roadway improvements are recommended by the consultant. LA 73 at Site Drive #2 (Full Access - Longwood Avenue Connection): The southbound and eastbound approaches are anticipated to operate at a level of service (LOS) of A during both AM and PM peak periods. No roadway improvements are recommended by the consultant. Longwood Avenue at LA 73: The level of services for the exit left turn from Longwood Ave. onto LA 73 remains at a C for the AM peak hour and goes from an E to and F for the PM peak hour. The level of services for the exit

7 right turn from Longwood Ave. onto LA 73 remains at a B for both the AM and PM peak hours. The level of services for the La 73 left turn onto Longwood Avenue remains at an A for both the AM and PM peak hours. No roadway improvements are recommended by the consultant.
