� • Case Number: 957-76 ��larch 3, 197b Page Four d ability to limit the use af County Road C-2 for industrial purposes. We suggest thai this Vaould be helpful to �i�e integrity and environment of the resident-ial area on the eas-� 5ide of Langton Lake. For ecoloqica� reasons, however, it may not be necessary or desireable to phys�cally rerr�ove all of the fill accommodaing the exist-ing Caun�y Road C-2 across Langtor� Lalce. Irrespective of th�s issue, it is important to ob�ain the additional r3ght-of-way far the ultimate cons�ruction of Mt. Ridge Road at this �ime. DRAINAGE �. 7he apprapriate handling o�F drainage is a most ir��portan� �lement of the total solution in this case because of it's impact on Langton Lake. The appiicant and his consultinc� engineer have met with the Ri ce Creek Watershed Di stri ct n3anagers and thei r consul tants revi e�•ri ng the propased drainage plan. The Board of Managers of the i•ratershed district Y`eapproved the "conceptual permit for the �IK Terminal, No. 75-4"'at their meeting of February 11, 1976. Th�s permit improves a cond3tion that inter�m ponding be provided sufficient '�o store a 1� year storm with a baffle �o ailow overflow at a rate of not mare than .5 feet per second. 2. The design for most of �he site is based on the use of a"baffle" recommended by the Rice Creek Waiershed consulting engineers. The lacation and function af these baff7es as i� relates �o the termina� site will be illustrated with large scale drawings and explained by the d�Q�1Cd11��5 consultant at the hearing. Charlie �-IoncheTl and Terry Kramer have re�iewed the proposals extensively with the app��cant's consultani. Their camments wi31 be appropr�ate ai th� meeting. 3. Attached to this report in Dravring No. + is a sma31 scale map of the overal� drainage district for Langton Lake. This d�strict is a part af an anaiysis conducted by your City consulting engineers relating to an overall storm drainage plan for the Ci�y of Roseville. Yau will note, that the property in ques�ion is but a small part of the overall drainage pattern, same of which flows through th� property in question from �he south tQ Langtan La�e. _Thus, any drainage solution 'For the applicant's property must involve the determination of a final drainage plan for the Lar�gton Lake Sasin. We 5uggest therefore,that it is very important for the Pl�nning Con�mission and Caunci1 to give seriaus consideration to initiating a fieasibility stud�� to incorporate a total drainage solution to the Langton Lake Basin a-� the time a decision is made on the application in quesiion. 4. Mr. Hanchell nates that if the conditions relevant to drainage are a�tached as a r�art of any approval considered to this application, iniiial developmer�� of the term�nal facilities could proceed while a drainage feasibility study for the area is in progress.
