What is status of silt removal from culverts and detention pond repairs? If work has not been completed, receiving a full CO from engineering side will require surety with letter indicating what surety is covering and timeframe for completion. Also need acknowledgement of outstanding amended drainage report and schedule for completion and submittal to City.

Senior Assistant City Engineer Development Services City of College Station College Station, Texas RE: Caprock Crossing Detention Pond 2 (SP)—14-00900177 Ms. Cotter: This letter is an update on the construction progress for the abovementioned detention pond. The detention pond varied from the original construction plans, however, detention pond and associated pond volumes are comparable to those of the construction plans and designed detention pond. The detention pond should function as designed to mitigate increases in stormwater runoff produced from upstream development. Modifications will still need to be made to prevent standing water in the bottom of the pond. Due to weather conditions the modifications to the pond will need to be postponed until we experience a substantial dry period to allow the pond to dry out. The developer has provided a financial surety for the remaining construction work and has given approximately 6 month time frame on completing the construction of the pond, weather permitting. Upon completion of the detention pond construction an amended drainage report will be submitted corresponding to the pond as built on site.

Based on the depth of sediment, underbrush and tree growth, this issue is clearly decades old and not caused by our construction. We do not intend to do any further work on the neighboring tracts - as we absolutely did not cause this obstruction. We are re -contacting the utility companies to get their written approval of this work. We are competing the hydroseed on the pond later this week. We understand full acceptance by the city will not occur until the pond is vegetated. As far as the pond holding water, we have struggled over and over to fix the pond bottom, but the fact that water continues to accumulate there (as intended) makes the fine grading very tough. Our intention is to keep plugging away at the pond bottom as dry weather permits. I understand the maintenance concern and we will address it one way or another.

Although this is an interim pond, maintenance is required which will be difficult if not impossible in current state. Pond will also need to be vegetated as well as other disturbed areas. You mentioned culverts partially plugged with sediment. Since it is not clear that it wasn't a result of construction activities, contractor should be responsible for cleaning them out in order for pond to function as intended. I am unable to find the response to staff comments No 2, which might address this, but more of the pond berm is constructed within the existing PUEs than previously approved. If you recall, I had concerns with the impact the berm would have on maintenance of the various utilities. There was minimal encroachment with pervious design. Did TMPA, BTU and Wellborn SUD have specific requirements for berm in PUE and provide consent? Please provide an amended drainage report reflecting new design. Thanks, Carol From: Carol Cotter Sent: Tuesday, December 09, 2014 2:55 PM To:'Deven Doyen' Subject: FW: Caprock Detention Hi Deven, Please see attached photos from today. Is contractor finished? Will pond drain? Flume above bottom of pond. Are Record Drawings reflecting current conditions or when pond finished? Also appears berm grading outside drainage easement. Carol From: Donnie Willis Sent: Tuesday, December 09, 2014 12:13 PM To: Carol Cotter Subject: Caprock Detention Carol, The DP has a portion of the levee reshaped but has been wallowed out into a mud pit. See attached photos. There is a track vehicle still on site. They may know they are not finished shaping the pond. It holds water in three places.
