• ORONO PLANNING COMMISSION MEETING <br />MINUTES FOR SEPTEMBER 15, 1997 <br />( #3 - #2294 LGA Investment Group - Continued) <br />The drainage is to the northeast and southeast through two ravines with culverts under Wildhurst <br />Trail and eventually to Forest Lake. The drainage to the south ravine is suggested changed to enable <br />drainage to flow to the north ravine. Applicant's plan uses the first 200' of the north ravine for a <br />drainage pond. This may be sound from an engineering standpoint but will impact the natural <br />characteristics of the ravine. This proposal was submitted after the original application submission <br />showing a pond in the northwest of the Sollner lot. It was changed apparently in response to the fact <br />that no area credit would be received for ponds. <br />Gaffron said the drainage plan will provide a benefit to the neighborhood. It should reduce the flow <br />rate as it leaves the subdivision. The City Engineer had suggested runoff controls located at the head <br />of the ravine. Gaffron said Staff had not expected the stormwater pond to be shifted to the ravine. <br />There are major trees (oak, maple, basswoods) growing in the ravine, creating a problem with having <br />a stormwater pond at the head of the ravine, since the slopes make this a fragile environment. <br />Gaffron reported that there is adequate area to meet the front, rear, and side setbacks for all lots, <br />some of which are located in the Shoreland District and subject to the 500 - 1000', 35% hardcover, <br />• limitation. The northerly ravine is not located in the Shoreland District. <br />The City Engineer has reviewed the preliminary plat and suggested sanitary sewer run from <br />Wildhurst Trail. The developer will be responsible for the cost to bring the sewer in. The applicant <br />must confirm that the streets meet the design, speed, and radius standards and include a typical <br />section with the plans. Gaffron indicated that due to the park land restrictions on the proposed <br />northern cul -de -sac location, no cul -de -sac can be located there, only an access road across it. The <br />cul -de -sac should be moved to the southeast, while maintaining a corridor for access to both the park <br />land and Hennessy property. The proposed island should be omitted or cul -de -sac widened for <br />maintenance. Erosion controls must be in place before any site grading and additional measures <br />taken along the steep slope between Lots 3 and 4 where sewer construction will take place. Pre and <br />post development flow rates will be required and need MCWD approval. A NURP stormwater pond <br />will be required. <br />Gaffron reviewed general issues for consideration and discussion, including stormwater pond <br />relocation. The current proposed location would result in the removal of numerous mature trees, <br />change the characteristics of the ravine, negatively impact the views from the adjacent park land, and <br />causes a single family residence to be located within 10 -20' of a pond. Gaffron said the cul -de -sac <br />should be moved toward the east and continue the corridor to the park land. The Park Commission <br />has not reviewed the application for park fee or 8% land dedication. Gaffron suggested land be taken <br />in the ravine area. With the total acreage required for park dedication, stormwater, and roads, it may <br />isbe that the development will only consist of 6 lots. <br />15 <br />
