Zoning Application #2114 March 11, 1996 Page 2 Brief Review of Application #1216 In 1987 applicant filed a conditional use permit and variance application to permit the removal of approximately 1.584 cubic yards of spoils from a Type 5 weMand involving one-third to one-half acre in area. The maximum depth of the.pond was prcroseo at 12'. The slopes would be at a 3:1 ratio. The purpose of the pond was to allow standin;: ai r t..- reduce algae growth and pond odors in the residential neighborhood. Review E.xhibits 1, J, K-1-2 and L. Cook's report n-u s sedimentation capacity will be increased and upgrade wildlife habitat. The improvement will reduce the assimilative capacity of the marsh as cattails and other vegetation would be eliminated in the deeper areas of pond but the depth would allow for the reduction in pond odors and minimize the algae growth. Review' E.xhibits M and N, the Citv'joined in the application when spoils to be removed were found to contain extensive pockets of yellow clav most suitable for restoration of Bohns Point Road. Bolms Point Road was dangerously close to the pond with a sharp drop from roadway. The banks were restored at a more gradual slope providing safer access for vehicular traltic. Review of Current Application Review Exhibits B. 11 and O, applicant's consultant notes southern area of the pond contains mud or sludee and branches where verv’ little vegetation grows. It is applicant's intention to cleanup the sludge and allow for additional storage area with vegetation to grow along the edge of the pond. The mud and debris will total approximately 80 cubic yards of spoils. On a recent inspection we found little sign of cattail vegetation within the pond or pond's edges. Staff is not aware of any need to increase water area of pond but does recognize a need to restore wetland vegetation in the shallower banks along the south side. Applicant's consultant should provide an amended plan showing shallower slopes that would allow the restoration of suitable wetland vegetation to increase assimilative capacity of pond lost in original 1987 application. Issues for Consideration 1 Review Exhibit D, note 1625 Bohns Point Road is now owned by a Norwest Bank Trust uroup. As majority of alteration involves 1625 Bohns Point Road, we should have confirmation of their approval of the land alteration. The Bank should also sign the resolution approving the proposed alteration. 2. As Engineer ’s report notes, the Corps of Engineers and the MCWD will not require a pemiit review for the maintenance dredging. We should question applicant ’s consultant as to how often this type of dredging would be necessary to maintain the pond as originally designed. The pond was installed nine years ago, what can be done to minimize the need lor future maintenance dredging?
