Don DeBaere and I met and reviewed the site with the property owner on October 20. The property receives significant amounts of offsite runoff that is contributing to a small ravine between 1359 and 1365 Park Drive. The attached map provides an estimated drainage area conveyed to the ravine. This ravine is currently small and does not extend into Lake Minnetonka, but will continue to erode and grow with time. During heavier rainfalls silt is washed into the lake. It does not appear that there is imminent danger to homes, but in time this may be more of a serious issue with its proximity to 1365 Park Drive's walkout basement. Options 1. Take note of the above information and consider placing this project in the stormwater CIP when it is updated. 2. Request an engineering study further defining the drainage area for the ravine and recommend possible solutions, associated costs, and possible funding sources. 3. Take note of the above information and do nothing. COUNCIL ACTION REQUESTED: Provide staff direction on one of the above options. �� - �� ; ' �'�� �` � 1\, \ \,` i� ` ,,I . � � �' ■ . � � � \ \ , �► , � ■ � � . .. . ,. �►� � r ,. . . .. . ► , .�� � �--.�. �!�. �♦�+� �.r ♦ � ! �'''�.' ♦ . .` � ��� , j1 . :• `� �i l�. _� . . � ' ����� ��� - . . . . �� �: � � `r\ � �-�`"-�. j . - . / � .; _�� �r : ..
