In Option #2 the cost of co~___structioa is $534,000 with the contract ~aking Skaggs responsible for $345,000, leaving a difference of $189,000. In option #3 the financial obligation by Skaggs exceeds the coastruction cost. At present ~e have approxt~ataly $74,000 of unallocated interest in the $trant C.I.P fund. If tim Council chooses option ~1 or ~2 this $?4,000 conld be applied to~ardthediffarence, but, the r~aindsr ~ould have to cam irma ss other source such u issuing certificates of obligation, or borrowing the s~ney.

FT/lr CO~SEAGG. 001 COPPELL PUBLIC WORKS ;~MORANDUM DATE: TO: VIA: FROM: RE: April 16, 1990 ~\~ Alan Ratliff, City Manager Steve Goram, Director of Public Work Shohre Daneshmand, P.E., Acting Cit neer~ Connell Skaggs Drainage Improvement Options We have reviewed the above referenced drainage improvement options as prepared and proposed byConnell Development's Engineer and have the following comments. Option #1, Construction of a 10' x 8' box culvert is the best alternative based on staff's review and recommendation. As an enclosed system, if built, it would be adequately installed in the existing 20' drainage easements with minimal maintenance needed. Please note that per the agreement between Skyhawk Venture/Connell Skaggs Development Co. and the City of Coppell, dated Dec. 11, 1988, there is a cap on the funds available in the amount of $345,000.00. Due to trench safety laws, the cost of such construction has increased. Per the attached cost estimate for option #1, presently funds in the amount of $728,000.00 is required to construct this drainage system. Additionally, please note that as per attached memo dated 2/14/90, Larry Jackson has indicated that we probably could require Boorhem & Hinckley to put in a box culvert just like we required Connell. Installation of 2- 4' x 12' box culvert and concrete lined channel, Option #2, is staff's second choice, which may be considered, but with the estimated total construction cost of $534,000.00, there would still be a limitation in availability of funds. At the present only $345,000.00 are available per agreement. Please note that staff has the following concerns on this option: ae Lack of adequate Drainage Easement (DE) in order to construct such drainage system, there would be a need for minimum of 30' D.E.. b. Existing fences would need to be moved back to accommodate for open drainage channel. c. Maintenance of such system is of a concern to staff. Option #3 would be a concrete lined open channel with the cost estimate of $259,130.00, from Sandy Lake Road to the High School culvert. Please note that staff would have the same concerns as listed for option #2; however, the proposed cost is $85,000 (+) less than the amount agreed upon in the agreement. Should this option be approved, staff recommends that the surplus funds ($85,000 +) be escrowed with the City for future maintenance of the channel and/or purchase of any related equipment for such maintenance. Staff along with Connell Development Representative will be available at the April 24, 1990, City Council meeting to answer any questions.

Ms. Jenkins expressed lots of concerns with the existing drainage situation in her back yard and indicated that she has never had such problem in the 30 years she has lived in this house until the new shopping center was put in place (refers to Connell - Skaggs Addition). Please note that we have also contacted the residents of Shady Dale, as shown on the attached list, and were able to talk to 6 residents informing them about the reference City Council item... drainage improvement options.., etc. which will be discussed in the up coming City Council meeting on April 24, 1990. Generally the residents are looking for some type of interim solution to the problem, such as cleaning up the existing ditch, to avoid drain water from washing up their back-yard, especially in Ms. Jenkin's case. Connell - Skaggs representative and engineer will be attending the April 24, 1990, City Council meeting along with city staff to answer any questions. Please let us know if you have any questions.

Lake Road to the southeast corner of Coppell High School where existing culvert ends. \ Acting City Engineer Shohre Daneshmand made the presentation to the \Council. Also present to discuss this item was Mr. Jim Coke \representing Connell Development. Mr. Coke stated that, since the \original agreement in 1986, there have been changes in trench \safety laws which, in effect, drastically change the cost of \installing a box culvert. Rather than the estimated $345,000 for ~his project, it is anticipated that $728,000 would be required. however, Mr. Coke indicated that another alternative that would ~eet the trench safety requirements and decrease the cost of the linstallation of the ~ox culverts to approximately $400,000, is /through the use of a trench box". Mr. Coke indicated that they /would be willing to participate up to the $345,000 with the City /or others providing the remaining funds. The time frame for /completion of this project would be approximately three months. /Councilman Robertson provided an additional alternative with the ~/ .... ~ ~ new method called a "blow form" that he felt would also ~ greatly reduce the cost of the installation of the box cu£ver · ~ citizens present who asked to speak were Mr. L.H. Davis of 100 ~ North Shadydale and Ms. Pauline Jenkins of 132 North Shadydale. I Both citizens expressed their concern with the damage and drainage I that was coming onto their property. It was also indicated to the Council that an existing ditch that was present prior to the I development of the Connell development had been graded over, thereby preventing proper drainage. Staff was requested to evaluate this situation. Following further discussion on this ~ item, Councilman Smothermon moved that this item be tabled to the , May 8, 1990 city Council meeting and that information concerning fcost of both the "blow form" and the "trench box" methods be evaluated. Councilman Morton additionally moved that the situation on the ditch at Shadydale be reviewed by Staff. Councilman Nelson seconded the motion; motion carried 7-0 with Mayor Pro Tem Wilkerson and Councilmen Thomas, Morton, Smothermon, Cowman, Robertson and Nelson voting in favor of the motion. Item 16. Presentation by Wayne Ginn, Inc. concerning the median opening just to the north of Grapevine Creek bridge on Denton Tap Road and speed study for Denton Tap Roads and South Beltline Road. Consulting Engineer Wayne Ginn made the presentation to the Council. Mr. Ginn indicated that his firm had employed the firms of both Barton-Aschman and DeShazo, Starek & Tang as additional consultants to study this intersection and have provided the following recommendations that will enhance the safe operation of the intersection: 1) remove the metal beam guardrail, 2) pursue having TU Electric relocate the power pole at the northeast end at the east bridge, 3) place ,,Intersection Ahead" signs for southbound traffic prior to the Meadowcreek intersection, 4) provide striping as recommended by DeShazo, Starek & Tang, 5) review the parking situation at the medical building on Meadowcreek and 6) lower the speed limit on Denton Tap Road to 40 miles per hour. Mr. Ginn indicated that he did feel that the barricades could be removed at this point and that the speed limit of 45 miles per hour is a safe speed. Questions raised during discussion on this item concerned that the consulting engineers look at the entrance onto Denton Tap from the Goodyear location, that City Staff conducting a study to consider lowering the speed limit on Denton Tap and installation of a traffic signal light at the Bethel School Road and Denton Tap intersections- Following discussion of this item, co oilman .orto- moved tha} city?u ?size .... ~- ~---iers at the Denton Tap ana meaaowcree~ removal oz ~u ,~ , - intersection subject to approval by the C~ty Attorney that the letters received from the consulting engineers ~re adequate in .ature to protect the City a.dthat.. i- £or a 90 ~ay ~lme perzou. ~--.~ · motion .tion carried .ith Councilmen Thomas, Norton, Smother~on, commas,. ~oner~son voting in favor of the motion.
