The budget provides for $1,000 and $4,000, respectively, consistent with 1986-87. The proposed adjustments for City memberships and dues will reduce by $9,500 the funding requirements from Hotel/Motel Taxes and require a net additional appropriation of $7,000 from City Council IS Budget Reserve for Contingency to the City Council Budget (+$9,500 for dues, -$2,500 for the Women's Center and Drug Abuse Programs, which are to be absorbed by the Police Department Budget). x X X X X X X X In the six weeks since the employment of the Economic Development Director we have developed a better knowledge of the needs of,the Promotional ~und than we had during the budgeting process last summer.

CONSULTING ENGINEERS / Fort Worth-Dallas November 12, 1987 ? Hr. Rodger Line, City Manager City of North Richland Hills 7301 N.E. Loop 820 North Richland Hills, Tex. 76180 Re: 3-336, CITY OF NORTH RICHLAND HILLS VATAUGA ROAD IMPROVEMENTS ALIGNMENT STUDY As instructed by the City Council in their regular meeting of November 9, 1987, we have prepared a realignment study of Vatauga Road from Smithfield to Precinct Line Road. Attached is a dra~ing showing the alignment possibilities investigated. Ve first looked at the possibility of changing the section from Smithfield Road to Davis Blvd. The current design, and contract alignment with Austin Paving Company, tor which right-ot-way has already been acquired and construction has already started, cannot be easily changed. The following are some reasons why we do not recommend changing this section: 1. The minimum safe radius of curvature of Vatauga Road for a 40-mph design speed is about 600-feet. As shown on the attached drawing, a 60Q-foot radius reverse curve from the design location at Smithfield Road to the Cardinal Lane intersection at Davis Blvd. will not work. A shorter radius of curvature would be required below the 40-mph safe limit. 2. The State Highway Department has already approved the existing Vatauga Road - Davis Blvd. intersection location. Their plans for future widening of Davis Blvd. already include this intersection location. 3. The right-of-way for the section of Vatauga Road from Smithfield Road to Davis Blvd. has already been acquired. 4. Grading by the Contractor, Austin Paving, of this section is complete. 5. An underground 12-inch water main has already been constructed in this section within the existing right-of-way. The crossing location of this 12-inch water line across Davis Blvd. at the existing Vatauga Road 1901 CENTRAL DR., SUITE 550 · BEDFORD, TEXAS 76021 . 817/283-6211 . METRO/267-3367 1- .( ," 1 I I I I I I I ,- I I I I I I I I I I November 12, 1987 V~~auga Road Alignment Study Page 2 intersection has already been approved and will be constructed shortly by the Contractor. 6. Underground storm drainage at this intersection is designed and under contract, and construction of these facilities are already underway. '7. The Yatauga Road construction contract totals $3,361,596.24, of which $351,449.58 has already been earned by the contractor. About 10-percent of the current work, or roughly $35,000 has been spent on the section between Smithfield and Vatauga· Road. 8. If the alignment in this section is changed, new right-of-way will have to be acquired and the existing right-of-way vacated. The excavated roadw~y would have to. be filled in. The new 12-inch water line would ·~have t6 be removed. Anew-permit from-the State Highway Department would have to be acquired-for the revi~ed intersection location at Cardinal .< ': :Lane. . (Any other location would create a skewed intersection angle which the Highway Department would reject). A new 12·inch water line boring permit would be required. New plans and specifications would have to be . prepared for this major redesign. A change order with the contractor would have to be negotiated. All of these items would require much more - time ~nd expense to ~ccomplished. Plans being prepared by the . consultants for the Highway Department for widening of Davis Blvd. would also have to be revised. This would take additional time and expense which would probably be passed on to the City of North Richland Hills. . . Based on the items discussed above, we do not recommend changing the existing alignment of Vatauga Road from Smithfield Road to Davis Blvd. As shown on the attach~d sketch, ~e have prepared an alternate alignment design from Davis Blvd.' to Precinct Line Road which curves northward from Davis Blvd. to line up with Cardinal Lane. This plan will work based'on the minimum 600-foot radius curvature criteria for a 40-mph design. A 600-foot radius curve would begin 100-feet from the current Davis Blvd.-Yatauga Road intersection and run for a length of about 450-feet. There would be a 185-foot straight-of-way section then another 600·foot radius curve would begin for a length of about 400-feet and end at the west line of the Charles Scoma property. A longer radius reverse curve could be used for a faster design speed (e.g. 926-feet for 50-mph), but the end of the curve would run through the Scoma property and cut across his north-west property corner at an angle to the current alignment of Cardinal Lane. The revised alignment of Yatauga Road would then follow the existing Cardinal Lane alignment past Amundson Road and then curve southeastward as shown on the I I I I I I I I I I I I I I I I I I I i" November 12, 1987 Vatauga Road Alignment Study Page 3 attached drawing. This curve would clip the southwest corner of the Billy Lee property slightly. Two possible alignments are shown from the north-south section of Cardinal lane eastward to Precinct Line Road. Ve have no objection to either of these alternate routes since they both end 'at the Precinct Line Road · Long Boone Road intersection as provided in the Thoroughfare Master Plan. Ve are available to discuss this study with you, the Staff and/or the Council at any time. Meanwhile, please call if you have any questions. w,~ RICHARD V. ALBIN,-P.E. RVA/ra, EncÌosures' cc.

I I 12 I ~ I I I Ie I I I I I I I t' I I I I I I Ie I I - When a tract of land is proposed for development and public improvements are to be installed the following policy will apply. For public improvements bordering between or para1le1ing two tracts of land under different ownership and participation is required by both owners. the developer desiring to plat his land first must do the following: ,.l Obtain the necessary right-of-way or easement from the adjoining property owner or owners and secure from those owners formal agreement to pay their portion of the improvement costs, or the first developer must make the improvements at his own expense. If the property owners being asked to participate in the improvements refuses to participate then the City may take the necessary steps to obtain the right-of-way or easement. Any developer desiring to plat his land first will pay to the City all costs involved in obtaining the right-of-way or easement. The City may then through a Ctty-Developer Agreement with the first developer desiring to plat his land agree to recover from the owner or owners of the adjoining property an amount equal to their share of the costs plus six (6%) per cent interest per year. The City will recover this amount at such time as the adjoining owners are ready to develop their property. The amount to be recovered for the first developer will be stated in a City-Developer Agreement. The agreement will. also state if six (6%) per cent interest is to be paid to the first developer. Where the action is applicable, the City may assess the adjoining property owner for the costs of construction of the street. The City may also levy interest on the unpaid balance of the assessment at the maximum rate allowed by State Law. \ \ ¡ \ If the first developer does not agree to the above requirements, he must construct all public improvements within the limits of his own subdivision. When a tract of land is developed and there are border or parallel improvements which are not required to be installed as a condit:1.on of development, the following policy is in effect. The developer of the first tract will provide as much of the easement or right of way as possible in his development but not less than one-half the needed right of way or easement. The first developer will also pay to the City an amount of money sufficient to Cover his share of the costs of improvements as determined by the Director of Publ:1c Works and the city Engineer-. P. V ARIA N C E S The Planning and Zoning Commission may recommend certain deviations to # the Ordinance which are deemed to be in the best interest of the City and the City Coundl may approve a variance from these subdivision regulations author1zin g the deviations when, in its opinion, strict com pliance with the Ordinance would not serve the public need. In granting a variance, the Council shall prescribe only conditions that it deems necessary to or desirable in the publ:1c interest. In making the findings herein below required, the Council shall take into account the nature of the proposed use of the land involved, existing uses of land in the vicinity, the number of persons who wm reside or work in the proposed subdivision, and the probable effect of such variance upon traffic conditions and upon the public health, safety, convenience and welfare in the vicinity. No variance shall be granted unless the Council finds: 13 - " I Ie I I I I I I I ,- I I I I I I -- I I ~i.~f ~' , \ \ \ \ 1. That there exists special circumstances or conditions affecting the land involved which when the strictist application of the provisions of this Ordinance :Is adhered to, would deprive the app1:icant of reasonable use of his land; and 2. That the variance is necessary for the preservation and enjoyment of a substantial property right of the applicant; and -....,. 3. That the granting of the variance will not be detrimental to the public health, safety or welfare, or injurious to other property in the area; and 4. That the granting of the variance wm not have the effect of preventing the orderly subdivision of other land in the area in accordance with the provisions of this ordinance. Such finds of the City Council, together with the specific facts upon which such findings are based, shall be incorporated into the official minutes of the Counill meeting at which such variance is granted. Variances may be ./ granted only when in harmony with the general purpose and intent of this - ~ Ordinance so. that the public health, safety and welfare may be secured and substantial justice done. Pecuniary hardship to the subdivider, standing alone, shall not be deemed to constitute cause for granting of a requested variance. 14 - I Ie I I I .~. I I I .".t I \ i \ -- I I '.

Preparation and presentation of the sketch plan is not mandatory and no approvals, either tentative or final, wm be given on sketch plans; however, their preparation is recommended as an economy measure to faci1:1tate the including of requirements and suggestf.ons prior to going to the expense of designing and drafting the pre1iminary plan. B. PRELIMINARY CONFERENCE At the time the sketch plan is presented to the Planning and Development Department, a pre1iminary conference should be held for the general comments and clarifications which are usually necessary. At that time, the Subdivider should obtain copies of the City's Subdivision Regulations V olu me I, and the City Master Plan for his own reference, and Volumes II and ill for the benefit of his engineer.

GENERAL SECTION 2-05 DRAINAGE The criteria herein provided shall govern the design of storm drainage improvements within the City of North Richland H:Ills. Improvements shall. include streets, alleys, storm sewers, channels, culverts, bridges, swales, and any other fadIity through which storm water flows. All drainage improvements shall be constructed in accordance with City specifications and be in dedicated right of way, drainage easement or flood way easement. The criteria of the Master Drainage Plan have been incorporated. Drainage run-off calculations will be related to property zoning and use (existing and proposed). The developer shall provide all the necessary easement and right of way required for drainage structures, including storm sewers and open channels with access ramps. Easement width for storm sewer pipe shall be not less than fifteen (15') feet, and easement width for open channels shall be at least forty (40') feet wider than the top of the channel, twenty (20') feet of which shall be on each side to serve as access ways for maintenance purposes. . . The developer shall be required to install at his own expense a11_ storm sewers and drainage structures. This policy is applicable to all drainage facilities including the main channels and tributaries of Mackey, Calloway, Walker, Little Bear and Mesquite Branch Creeks, but excepting Big Fossil - Creek. The developer shall be responsible for excavation on the fully urbanized one hundred (100) year frequency discharge for the channel, unless otherwise approved by the City Counell. ~ \. B. BASIS OF DESIGN o 1. RATIONAL METHOD: The method of calculation/for storm runoff for drainage areas less than one thousand (100ý acres will be the Rational Method. The method is expressed by the foJlowing equation: Q-CIA Q - storm diséharge' at th'e design point in cubic feet per second. C runoff coefficient representing the ratio of peak runoff to the rainfall. ~. I - average rainfall intensity for the time of concentration at the design point in inches per hour. A - area contributing runoff to the point of design in acres. 2. UNIT H Y DR 0 G RAP H ME THO D : Peak discharges for drainage areas exceeding one thousand (1000) acres shall be determined by using the unit hydrograp h method. The unit hydrograp h for this method shall be developed by using the criteria as outlined in "Flood-Hydrograph Analysis and Computation", U.S. Army Corps of Engineers, Engineering and Design Manuals, EM 110-2-1405, Washington D.C. dated August 31,1959. A unit period of 15 (15) minutes should be used for the determination of the unit hydrograph. so I Ie I I I I I I I ~ \ \ , -- I I I I I I Ie I I J.

Sizing based only on normal depth calculations will not be approved unless it can be demonstrated that such downstream backwater effects can be safely ignored, or future downstream improvements are being made which will lower the controlling downstream elevation below normal depth 8S determined using the Manning's Equation. In cases where the top of channelIiner must be constructed above natural ground level as required to fully contain the one hundred (100) year flow, and where construction of levees or berms are permitted, provision shall be made for draining the local runoff which ponds behind the levees after the water 55 I Ie I I I I I I I Ie I I I I I I Ie I I surface in the channel recedes. Finished floor elevations may be established at least 1.5 feet above the peak one hundred (100) year water surface which ponds behind the levees, 1£ approved by the Public Works Director. .' . If levees are not approved by the Public Works Department, then compacted earthen fill shall be placed along side the channel within the entire flood plain area as required to concrete line the channel to a height of one (1') foot above the fully urbanized one hundred (100) year water surface elevation. Side slopes of the channel banks behind the concrete channell1ner shall be no steeper than five (5') foot horizontal to one (1') foot vertical within the drainage easement, or for a distance of not less than twenty (20') feet minimum behind the top of channel. Side slopes beyond the twenty (20') foot minimum shall be no steeper than three (3') foot horizontal to one (1') foot vertical unless concrete lined or covered with approved soil erosion protection materials. If fencing :Is required t it shall be placed along the top of the concrete channel liner unless a sanitary sewer main or water line is located within an easement along the channel bank, in which case the fence shall be located on the easement line to permit unrestricted Pub1ic Works access to the utiIity line. ~f Partial concrete Liner: If the one hundred (100) year fully channel - contained water surface is above the natural ground l1rie and levees are not app roved or flood p1ain fill. is not feasible, then the concrete channel liner shall be extended to the natural ground line along each side of the channel. In no case shall the concrete lined capacity provided be less than that required to convey the twenty-five (25) year frequency discharge. Floodway easements shall be provided along the sides of the concrete lined channel sufficient to encom pass all areas beneath the water surface elevation resulting from a fully urbanized one hundred (lOO) year discharge, plus such additional width easements as may be required - to provide ingress and egress to allow maintenance and to protect a4jacent property against erosion t caving-in of over-banks, etc. t as determined .and r.equired by the Public Works Department. The Developer shall be responsible for furnishing complete cross-sections, grading plans, HEC-2 computer runs and all other documentation requested by the Public Works Department as required to justify less than full section concrete channel lining and to establish the limits of the one hundred (100) year overflow flood pLrln Jines. Water surface profile calculations shall be based on backwater effects created by an existing bridge, culvert or other obstruction regardless of future downstream proposed improvements. \ Earthen channels; Earthen Channels may only be constructed after specific approval of the City Council. Approval may be given only if the following stipulations are met: 1. That the velocity of flow will not produce serious erosion. 56 - I Ie I I I I I I I \ \ . i~ i' I I I I I I -- I il f 2. That sufficient easements are dedicated to provide protection of adjacent properties or facili.t1es. 3. That flood way easements are dedicated to encompass the area below the elevation of the water surface profile of a fully urbanized one hundred (100) year frequency storm, plus one foot of freeboard and any additional area necessary to provide access and maintenance, but not less than sixty (60') feet in wid th . . .. M 4. That arrangements have been made for perpetual maintenance by the adjacent property owners or has been dedicated and accepted for City Park purposes; and s. That, in the judgement of the Public Works Director, the appropriate use of the neighboring property or the health and safety of persons affected will not be substandally injured. Earthen Channels, when approved, shall be constructed with a trapezoidal shape and a minimum bottom width of twelve (12') feet and side slopes not steeper than three (3') feet horizontal to one (1 ') foot vertical (4 to 1 preferred). A reinforced concrete pilot channel not less than (12') feet in width or, as determined by the Public Works Director, shall be constructed. The side slopes shall be smooth, free of rocks, and contain a minimum of six (6") inches of top soil, and shall be placed a minimum of four (4') feet along both sides of the pilot channel to a depth of at least two (2') feet. Size and gradation of such material shall be determined based on peak discharge velocity requirements. The pilot channel shall be constructed as approved by the Public Works Department. The easement width for earthen channels shall extend at least twenty (20') feet beyond the top of each channel bank. . c After proposed earthen side slopes are cut, slopes shall be covered by grass according to the City's specifications. The grass shall be planted to two (2') feet outside the top of banks. The water surface profile (hydraulic grade line) for the one hundred (100) year freq uency storm shall be shown. Maximu m permissible mean velocities for the one hundred (100) year frequency discharge shall be eight (8') feet per second. In partially concrete lined channels and fifteen (15') feet per second in fully concrete lined channels. Special consideration should be given to outlet structures on channels where concrete lining meets earthen banks when velocities exceed eight (8') feet per second. 57 ~",Þ·.~.. ~ I Ie I I I I I I I '\ ~ t' I I I I I I Ie I I - Reinforced concrete access ramps shall be provided at all intersections of the channels with public streets. Access ramps shall be a minimum of twelve (12') feet wide with a maximum slope of sixteen (16%) percent. 11. Bridges and Culverts: An bridges and culverts shall be designed in accordance with the current edition of "Hydraulic Manual" prepared by the Texas Department of Highways and Public Transportation, Bridge Division. The funy urbanized one hu ndred (100) year freq uency storm hydrauUc grade line shall be plotted. All culverts shall have head walls and wingwalls upstream and downstream. All culverts shall pass the fully urbanized one hundred (100) year frequency storm runoff without allowing runoff to pass over the road. All bridges shall have channel bottom and slopes concrete lined. The low point on the bridge structure shall be one (I ') foot above the fully urbanized one hundred (IOO) frequency storm water surface. 12. Lot Grading: Lot grading shall be conducted in a manner which will not allow runoff to cross more than two (2) lots (including the lot on which the drainage originates). If this is not possible, then a drainage easement must be provided and any necessary facl1it:i.es shall be constructed and installed by the developer. Finished floor elevations shall be set one (1') foot above the top of curb at the centerline of the lot or one and one half (1-1/2') feet above the one hundred (100) year frequency storm water surface elevation, whichever is the big her. 13. Off-Site Drainage: In respect to off-site drainage the following provisions shall apply: A. The Developer shall be responsible for all runoff from fully developed property upstream of his proposed development. Runoff coefficients utilized to design drainage systems for the properties involved shall. use the current zoning andlor the future use of the property as shown in the Future Land Use Pian contain.ed in the City's Master Plan, whichever is the most intensive use. B. Effect of the develop ment's drainage design on downstream properties and adjacent properties shall be given proper consideration. Yater concentrated in streets, pipes, drains, culverts, and channels will be moved to a recognized watercourse without damage to intervening structures or undue spreading across intervening land. A "recognized watercourse" shall herein be defined as either an open channel with hydraulic characteristics which provide capacity for at least a ten (10) year freq uency storm after ultimate development of its watershed, or an underground storm drain with capacity for at least a five (5) year frequency storm plus overland relief sufficient to safely discharge up to a combined ten (IO) year frequency flow 58 I Ie I I I ". .. I I I /' I \ \, f' I I I I I I Ie I I - (based on ultimate watershed develop ment) without damage to adjacent property. Such ten (10) year capacity shall exten d at least one hundred (100') feet downstream from the p,oint of discharge or from the Developer's property line, whichever is the greater distance. Typ:lcal examples of such "recognized watercourses" are the main channels of mackey, Calloway, Walker, Big Fossil, Little Bear, and Mesquite Branch Creeks, or those tributary creeks, streams, channels, or under ground storm drains which meet the hydraulic capacity requirements of a "recognized watercourse". The Developer is responsible for constructing all off-site channelization or underground storm drain w:U:h overland reHef, required to discharge concentrated storm water from the low end of his development to the recognized watercourse, and also to obtain an the necessary easements from intervening land owners. Calculations wi1l be required to show that connecting off-site drainageways are capable of handling any increase in runoff due to development, concentration, or diversion for at least the ten (10) year storm frequency. Any drainage or flood way easements necessary due to the Developer's alteration f existing concentrated discharge locations (i.e., existing creeks, channels, or storm sewers) shall be acquired by the Developer at no cost to the City. c. 'Where the pre1iminary drainage study by the developer indicates. that additional runoff from the developing property shall overload downstream drainage fad1it:1es and result in hazardous conditions, the City may withhold approval of the development until appropriate provisions have been made. These provisions shall include any drainage studies or plans necessary to indicate the off-site drainage problem will be corrected by off-site drainage construction. D · 'When req uired, the Develop er will furnish to the City, a "hold harmless agreement" and a "release of liability" indemnifying t~e City of North Richland Hills from any liab:llitles due to damages caused to the downstream property owner by the discharge of storm drå.inage water from the said development. 59 I Ie I I I I I I .;,- \.
