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 12.

5. 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

WWW.CSRSONL INE .COM

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 17-4045 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.

WWW.CSRSONL INE .COM

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.

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
