Subject: SDP200900009, Arden Place, Critical Slope Waiver Request
Date received: 1 June 2009
Date of Comment: 11 June 2009
The request for a waiver to develop on areas of critical slope for grading incorporated with proposed development
on TMP 61 -124 was received on 1 June 2009. The existing critical slopes and proposed grading are shown on the
Preliminary Site Plan dated 1 June 2009.
The engineering analysis of the request follows:
Description of critical slope area and proposed disturbance:
The critical slope areas within TMP 61 -124 contain both natural and presumably manmade critical slope
areas. Please the applicant's waiver request for details on these areas and the percentages of
disturbance.
Disturbance to the slopes impacted in the construction of the roads from Putt Putt Place and the
Woodbrook Subdivision stub -out to the development are exempt from the requirement of a waiver under
Section 18- 4.2.6.c for accessways. The remainder of the critical slopes disturbance is for the
construction of the Clubhouse and adjacent parking. This is in the area of the presumable manmade
critical slopes.
Below, each of the concerns of Zoning Ordinance section 18 -4.2 is addressed:
1. "rapid and/or large scale movement of soil and rock ": The areas of critical slope
disturbance are slim bands of what is presumed to be a fill area from the construction of the
mall. Large scale movement of soil and rock is not anticipated to occur as a result of this
construction.
2. "excessive stormwater run - off ": Conceptual stormwater management, as shown on the
preliminary site plan will be refined prior to Current Development engineering approval of
the final site plan. Excessive stormwater run -off is not expected to occur.
3. "siltation of natural and man -made bodies of water ": The applicant will submit an Erosion
and Sediment Control Plan with the Final Site Plan which will be reviewed for County and
State compliance. Proposed E &S measures are anticipated to reduce sediment -laden runoff
from leaving the site. Inspection and bonding by the County will monitor maintenance of the
erosion control facilities during construction. Proper stabilization and maintenance will
achieve long term stability.
4. "loss of aesthetic resource": The disturbance of the existing critical slopes with this
development involves the removal of existing vegetation.
5. "septic effluent ": The existing subdivision is served by public sewer and there are no septic
drainfields within the area of this disturbance.
No portion of this site plan is located inside the 100 -year flood plain area according to FEMA Maps,
dated 04 February 2005.
Based on the above review, the applicant has satisfactorily addressed the technical criteria for the
disturbance of critical slopes.
