It is a documents that is signed and <br />notarized by both the city and the client. The document is then recorded with Lane County. Those documents (plans and <br />recorded conditions of approval) are then use as part of the building permit review. <br />The proposed stormwater solution for that individual lot will have to adhere to the conditions of approval and the approved <br />stormwater management plan for the PUD. It will also have to adhere to the stormwater requirements for individual lots. <br />Public works staff reviews and approves (or doesn't approve) solutions proposed during the building permit phase. <br />2 Can you direct me to the portion of the stormwater analysis that accounts for the runoff/flow from these lots? <br />[ces] Water is accounted for this run off. The lots will need to retain the runoff to exist pre-development flows. <br />The storage container under the road is designed to handle a particular peak rate, <br />The lots in questions all flow to those roads and then to those containers. <br />The containers are only required to accommodate a 10 year storm. <br />Once a larger storm event happens the overflow is directed to either the level spreader whose destinations is the forest to <br />the east and then to the park property to the east. <br />Or to the ditch along the gravel road to the north in Hendricks Park. <br />All of this is designed so that the stormwater flowing down Capital Drive is no greater than it currently is. <br />Peak rates are designed to snatch existing. <br />1 <br />
