Adjournment I Ie I I I I I I I Ie I I I I I I I I I INFORMAL REPORT TO MAYOR AND CITY COUNCIL No. IR 89-16 Date: March 13, 1989 Subject: Senior Accountant Position As discussed February 13, 1989, at the Pre-Council Meeting, establish- ment of a Budget Office involved the transfer of an employee from the Finance Department. The City Council was advised that the duties related to the vacant Finance Department position would be reviewed and reported to Council prior to any action. After an in-depth review of the Senior Accountant's duties, it has been determined that on an annual basis, approximately 25% of the previous duties have been related to budget preparation. The remaining 75% involved the capital improvement program, investment of arbitrage restricted funds and special projects. Deletion of this position would result in a realignment of the non~ budget duties noted above and ultimately the nontime1y performance of several important duties (e.g. bank reconciliations, -fixed asset detail maintenance and investment collateral valuation). The timely performance of these duties is essential in safeguarding of the City's assets. The deletion of this position would seriously restrict the operating effectiveness of the Finance Department. Therefore, it is our recommendation that the vacant Senior Accountant position be filled. As discussed previously, funding of the Budget Director's position was provided with amounts budgeted for the Director of Management Services leaving the funds intact for the Senior Accountant. Although formal action is not required by City Council, your guidance in this matter is requested. R~~~ubmitted' Rodger N. Line City Manager L ISSUED BY THE CITY MANAGER NORTH RICHLAND HillS, TEXAS I Ie I I I I I I I -- I I I I I I I I" I INFORMAL REPORT TO MAYOR AND CITY COUNCIL No. IR 89-17 Date: March 13, 1989 Subject: IMPACT FEES; Status of Implementation With the passage of Senate Bill 336, (SB336), a deadline of June 20, 1990 was set for' all cities to have their "impact fee" charges meet the requirements of this legislation or no longer charge said fees. An "impact fee" is defined as a charge or assessrœnt imposed by a political sul:x:1ivision" against new developnent in order to generate revenue for funding or recoùping the costs of capital improverænts or facility expansions necessitated by and attributable to such new developnent. As used in SB 336, the term "impact fee" includes arrcrtized charges as well as lump-sum charges and includes capi tal recove:ry fees, contributions in - aid of construction, and any other fee which functions as described in this definition. OUr water and sewer pro rata fees, street escrow fees, and traffic signal pro ,rat;.a fees all fit this definition. On October 12, 1987 the City Council passed Ordinance No. 1503 which directed the staff to develop and implerænt a drainage impact fee in accordance with SB 336. The staff and our consul tants accanplished the developnent of the impact fee in September, 1988. The Capital Improvements Adviso:ry Ccmni ttee was made aware of those findings, but have not to date notified the Council of its recorrmendation with respect to implementation of the drainage impact fee. A letter of recorrmendation fran the Capital Improvements Adviso:ry Ccmni ttee has been pranised wi thin the next tw:> ( 2) weeks. Currently, no action has been taken to develop a capital improvements plan in accordance with SB 336 for future water and sanita:ry sewer , improvements necessary to . serve fut~ developnent. A portion of the ~ work for this water and sanitary sewer "impact fee" study has been accanpli'shed wi th the Çrainage impact fee study. The" land use assumption" plan has been developed and the canputer model for moni taring the program has been designed. Sane minor modification to each will be necessary. We estinate the total consultant fees for the water and sanitary sewer impact fee study to be approxinately $60,000. We reccmnend the Council instruct the staff to request proposals fran our consultants for the impact fee study. Upon receipt of these proposals, we will cane to you for further consideration of this matter.

Mr. S10an stated he had spent one year working on this project and had made a compromise suitable to all. Mr. Sloan stated he would be happy to answer any questions the Council might have. Mr. Sloan stated that on severa1 occasions Mayor Pro Tern Davis had stated to the attorney that he had an interest in 1and nearby and he assumed the attorney ru1ed this was not a conflict. Mr. Sloan stated he would like to know where the land was that Mayor Pro. Tem Davis was referring ~o. I I I I I I I I I I I I' I I I I I I I ".' ~ February 27, 1989 Page 3 Mayor Pro Tem Davis stated that at this time he had an interest in a piece of property at Douglas and Starnes which was zoned single family. Mayor Pro Tern Davis stated that in the past he had bought two lots in the adjacent addition and had since built homes and sold them. Mayor Pro Tern Davis stated he had an interest in the property because he felt it was a great area to build homes in and intended to build in the area again. Mayor Pro Tern Davis stated he did not own any property adjacent to the property in question. Mr. Sloan asked Mayor Pro Tern Davis if the attorney was aware of the past and present situation when he made his ruling. Mayor Pro Tern Davis stated that when this came up a year ago the same question was asked because of his interest in building homes in this area. Mr. Sloan asked the Council to approve the request because it was made in good faith. Mr. Jarrett Miller, 6821 Old Mill Road, appeared before the Council. Mr. Miller stated a compromise was worked out and he was still in support of the request. Mayor Brown called for anyone wishing to speak in opposition to the request to please come forward. Mr. Tom Duer, 7313 Londonderry, appeared before the Council. Mr. Duer stated he had concern on R-8 Zero Lot Line Zoning. Mr. Duer asked if there were presently any R-8 zonings in the City. Mr. Line stated yes, that Westchester Homes was R-8. Mr. Duer stated he had driven by a subdjvision that had about 40 houses on the street and 30 were vacant, 8 were rentals and 2 were occupied by homeowners. Mr. Duer stated he felt R-8 zoning on this property would result in rent houses or vacant houses. Ms. Brenda Bishop, 7401 Bursey Road, appeared before the Council. Ms. Bishop stated she was a member of the homeowners association and they would like to keep the north end of the City with quality development. Ms. Bishop stated smaller homes would become rent houses. Councilman Garvin asked Mr. Sloan did he originally want all of the property to be C-I zoning. Mr. Sloan stated yes, and he would still be willing to accept that. Councilman Garvin stated there might be some way to compromise but it would not be with R-8. I I I I I I I I I I I I I I I I I I I ".' . February 27, 1989 Page 4 Councilman Metts advised he had received an abundance of calls in opposition to the R-8 zoning. Councilman Metts asked Mr. Sloan if he planned to build there at the present time. Mr. Sloan stated that first he would like to comment that notices were sent to all residences within 200 feet and there were people here tonight for the first time. Mr. Sloan stated they. did not have a buyer at the present time. Councilman Garvin advised that all Council Members had received a letter, dated February 14, 1989, addressing this issue which was signed by Bill.J. Fenimore. Councilman Garvin stated Mr. Fenimore owned 80 lots in the Western Oaks Addition immediately east of the referenced case and that Mr. Fenimore concurred with the C-l and R-3 zoning but felt the R-8 would be detrimental. Councilman Garvin stated that this was Mr. Fenimore1s position and he just wanted to state it for the record. Councilman Welch stated he would like to restate his position of last week. Councilman Welch stated this case had been before the Planning and Zoning Commission on two occasions and turned down. Councilman Welch stated he maintained that the Council should uphold what the Planning and Zoning passed and also take into consideration the residents this would affect. Mayor Pro Tern Davis stated he and Mr. Fenimore owned property at Douglas and Starnes and asked the City Attorney, for the record, if that constituted a conflict, on his part, as far as the zoning on this case. Mr. McEntire replied no. Mayor Pro Tern Davis asked the attorney if it would preclude him from voting on this because last year he owned adjacent property. Mr. McEntire replied no. Mayor Pro Tern Davis stated he would also like to ask the Council if they felt there was any conflict of interest because he had built homes adjacent to this property and would it be a conflict of interest. Councilman Garvin stated he felt it had been clearly addressed by the City Attorney that there was no conflict. There being no one else wishing to speak Mayor Brown closed the Public Hearing. Councilman Garvin moved, seconded by Councilman Sibbet, to approve the C-l and R-3 zoning, deny the R-8 and there would be no cost for refiling an application on the R-B. Motion carried 5-0. Mr. Line advised that the appraiser for Smithfield Road assessments would not be here and the property owners would be renotified when the public hearing would be held. .

February 27, 1989 Page 6 Mr. Burk Collins, 8251 Bedford Euless Road, appeared before the Council. Mr. Collins stated he was here to ask the Council to approve the use of concrete tilt walls on houses in the Stonybrooke Subdivision. Mr. Collins stated he felt this request was not out of line because of where the subdivision was located. Mr. Collins stated this property was bounded on the west by industrial, on the south by a railroad and on the north by R-2. Mr. Collins stated he had a builder that was ready to build in the subdivision and the subdivision could be completed in a year. Mr. Collins stated these houses were stronger constructed than the normal frame houses. Mr. Collins stated the houses would have tiles roofs and the fire rating was much better than on the normal houses. Councilman Garvin asked Mr. Collins if he had ever built any tilt wall houses of this type. Mr. Collins stated no, but he had built tilt wa.ll warehouses. Councilman Garvin asked what knowledge he had of houses that had been built for a number of years in an area where it reflected durability similar to our climate and soil conditions. Mr. Collins stated the man that designed these houses and had a patent had been building them for a number of years. Mr. Collins stated the designer had quite a few of these type houses in Summerfields and in south Arlington. Councilman Metts asked if the City staff had seen and approved the plans. Mr. Collins stated yes. Councilman Welch asked if this was a variance from the Zoning Ordinance. Mr. Line quoted the following from the Zoning Ordinance: "residential dwellings on a residential lot shall have exterior walls consisting of at least 75· percent brick, stone, or if approved by the City Council, other masonry or materials of equal characteristic". Mr. Line stated it was a variance to the extent that Council action would have to be taken. Councilman Sibbet asked what the possibility was of the foundation or walls cracking when settling begins. Mr. Collins stated that in his opinion there would be less cracking on this type of house than other types. Mr. Jack Roseberry, 8912 Martin, appeared before the Council. Mr. Roseberry stated he was assisting Mr. Lollins in marketing this subdivision. Mr. Roseberry stated several consultants had been consulted and the top recommendation were the homes with the concrete tilt walls. Mr. Roseberry stated this type of housing was approved by FHA.

February 27, 1989 Page 7 Mayor Pro Tem Davis stated he would like the Council to have a recommendation from the Planning and Zoning Commission and input from the staff on the technical aspects on this type of structure. Councilman Metts asked Mr. Roseberry how many of these type of houses they plan to construct. Mr. Roseberry stated it would depend on the demand. Ms. Myrtis Byrd, 7312 Hialeah Circle, appeared before the Council. Ms. Byrd asked what the square footage of these houses would be. Mr. Fluitt replied 1,400 to 1,500 square feet. Ms. Byrd stated she had seen these houses and they looked like motels. Ms. Byrd asked Council to deny the request. Mr. Charles Scoma, 8300 Cardinal Lane, appeared before the Council. Mr. Scoma stated he was not so much against the request but did feel their needed to be additional study. Mr. Scoma stated he felt it was premature to deny or approve the request. Councilman Welch moved to deny GN 89-21. Motion died for lack of a second. Councilman Metts moved to table this request until the next meeting. Motion died for lack of a second. Mayor Pro Tern Davis moved, seconded by Councilman Garvin, to send the request to the Planning and Zoning Commission for their recommendation and for the staff to provide a study on the structure and soil conditions for this type of building.

Mayor Brown instructed the City Secretary not to place Mr. Collins on the Agenda in the future unless Mr. Collins came in and requested it. Mr. Harvey Fornof, representing ABC Wrecker, appeared before the Council. Mr. Fornof stated that he did not believe that what was being said about the zoning and the storage yard was not correct. according to the contract. Mr. Fornof stated he did have storage facilities in Keller. Councilman Garvin stated he was under the impression that Mr. Fornof was operating in the City of North Richland Hills, was that not correct. Mr. Fornof replied yes, he was also operating in North Richland Hills. Mayor Pro Tem Davis asked if he offered the storage site in Keller in his bid. Mr. Fornof stated the specifications did not ask for a location. Councilman Garvin asked if the site in Keller had a fence, other than barb wire, and 24 hour security. Mr. Fornof stated it was a stockade type fence. Councilman Garvin asked Mr. Fornof if hé did not primarily operate on Flory Street. Mr. Fornof replied yes, and he was operating within his rights, under C-2 zoning and under twenty percent lot usage. Mr. Fornof stated the only thing that would not be right would be to have the premises used and he did not need to use it. Mr. Fornof stated they had applied for rezoning. Mayor Brown asked Mr. Hazel (owner of the property) if he had applied for rezoning. Mr. Hazel stated they had petitioned for rezoning and were turned down. Mayor Brown asked if he planned on resubmitting. Mr. Hazel replied yes. Mayor Pro Tern Davis stated this had gone through a hearing previously and was denied and apparently the storage facility for junk and wreck cars had continued to be used for a year. Mayor Pro Tern pavis stated there was no I I I I I I I I I I I I' I I I I I I I . . February 27, 1989 Page 10 guarantee in resubmitting the zoning application that it would be approved and he did not want a storage lot in the middle of the City. Mayor Pro Tern Davis stated that, based on the staff report, the property was in nonconformance and the contract had been awarded to a company that was in conformance. Mayor Pro Tem Davis advised Mr. Fornof that it would be a year before the contract was bid again and in that year if someone could bring the building up to code and it could. be properly fenced they could bid it again. 26. ADJOURNMENT Mayor Pro Tern Davis moved, seconded by Councilman Garvin, to adjourn the meeting. Motion carried 5-0. Mayor ATTEST: City Secretary CITY OF NORTH RICHLAND HILLS Economic Development 3/13/89 Public Hearing to consider Adoption of a New Council Meeting Date: GN 89-27 Agenda Number: Subdivision Ordinance, Ordinance No. 1579 I I I I Over the past several months the Planning and Zoning Commission and the Staff have been involved in a rewrite of the Subdivision Ordinance. Working in harmony with Engineers who practice in the City of North Richland Hills, the Commission has created a new Subdivision Ordinance. The Commission felt that a new Ordinance was needed in lieu of revising the old Ordinance. The new Ordinance, as presented, removes technical requirements from the Ordinance and places these requirements into a Design Manual. The Commission felt that this action would give the City more flexibility in maintaining up to date design standards. The Commission is recommending that the Council adopt the Design Manual by Resolution in lieu of an Ordinance. Flexibility is thereby gained as changes to the Technical Design Manual can be made without going through the long process of passing an amending Ordinance. The Commission wishes to focus Council's attention to Section 1-01, subsection D, Paragraph 1, which will allow owners of unplatted property to make repairs and remodel with limitations without platting their property. This rewrite is a complete departure from the present Ordinance. The Commission, however, felt that the City was unduly penalizing homeowners who, under the present Ordinance, could not make a minor repair without spending $1,000 to $1,500 to plat their property. 1_ City Council action was deferred until further input was done by the Engineers. I I RECOMMENDATION: The City Council should hold the Public Hearing and act on the recommendation of the Planning and Zoning Commission to approve the proposed Subdivision Ordinance as submitted.

GN 88-104 PUBLIC HEARING TO CONSIDER ADOPTION OF A NEW SUBDIVISION ORDINANCE Mr. line stated he had just 1earned that some of the engineers that worked with the Staff had not reviewed the Design Manua1 that was before the Counci1 for approva1 under Item No. 18. Mr. line stated the staff fe1t that it was important that the engineers who worked with this dai1y have an opportunity to review and comment on what was being proposed. Mr. line suggested that the Counci1 hear anyone present wishing to speak on the proposed Subdivision Ordinance and continue the hearing at some future time and no action be taken on Items No. 17 and 18. This wou1d a110w the engineers a chance to review and comment on the manua1, if they wished to do so. . Mayor Brown opened the Pub1ic Hearing and ca11ed for anyone wishing to ~ speak to please come forward. Mr. Mark Hannon, Engineer, appeared before the Counci1. Mr. Hannon stated he was one of the engineers that worked with the staff on the Subdivision Ordinance. Mr. Hannon stated there were two items that he felt were important that had not been inc1uded. Mr. Hannon stated that one was the exemption to properties over five acres. . Mr. Hannon stated that the definition of a subdivision inc1uded resubdivisiön-or rep1at, but it did not inc1ude the division of land for 2ºric~1ture purposes in parcels or tracts of 1and five acres or more not involving any new street, a1ley or easement. Mr. Hannon stated he thought that this came from some State enab1ing 1egis1ation for genera1 1aw cities, and probab1y shou1d not app1y to home ru1e cities. Mr_ Hannon stated as an engineer he was opposed to this and as a citizen he was oPPo$ed to it from a safety standpoint. Mr. Hannon stated the second item was that the City wou1d participate in the cost of oversizing, providing that funds .were available.

If the value of such construction does not exceed fifty (50) percent of current value of the existing structure. 2. In residential subdivisions, Building Permits will not be issued until all public fac:Uit:1es approved in the construction plans have been installed and inspected by the Public Works Department. 3. In commercial and industrial subdivisions, Building Permits may be issued upon completion of the utility systems to a point where required fire hydrants and fire protection systems have been installed and are functional to provide protection for the buildings under construction. In cases where Building Permits are issued prior to all public facilities being completed, no Certificate of Occupancy for any building will be issued until such time as all construction of public fac:llities has been completed and accepted by the PubJic Works Department. '- 4. The City will not issue building permits on any subdivision which remains unapproved by the Public Works Department for a period of four years or more from the date of the Final Plat approval until a current engineering review of said plat has been conducted. 5.

B. PLACE FOR FILING AND COPIES REQUIRED The subdivider shall file the Preliminary Plat with the City by completing the Preliminary Plat App1ication and Checklist and submitting the appropriate ff1ing fees to the Planning and Zoning Coordinator. C. FORM AND CONTENT The Plat shall be drawn on sheets which are a maximum of 24" X 36" in size, with a binding margin of not less than 1-1/2" on the left side of the sheet. The plat shall be drawn at a numerical scale no greater than 1" = 100'. At the Engineer's discretion the plat may be drawn at a numerically smaller scale, i.e., 1" = 50', 1" = 40', etc. 1£ the plat can still be drawn on the required 24" x 36" sheet size including all titles, dedications and other required data. Whenever the size of the subdivision is such that the full area cannot be covered on a single sheet with space for titles and other required identification, the plat may be drawn on a number of separate sheets with matching lines to facilitate the joining of the individual sheets together as a composite drawing. Where more than one sheet is so used. they shall also be accompanied by a composite drawing of the individual sheets reduced in scale so to fit on a single sheet to serve as a general location map of the project. The Preliminary Plat shall show the following: 1. Proposed name of the subdivision, which shall not be a dup1ication of any existing subdivision name, whether by spelling'or pronunciation, or any other subdivision within the City or within its extraterritorial juri....sdictlon, unless the proposed subdivision is a subsequent filing or replat of the existing subdivision. 2. Names and addresses of the developer/subdivider, record owner. engineer, land planner, and surveyor. 3. The location and dimensions of all proposed streets, alleys, blocks. lots, parks, other public areas. reservations. easements or- other right of way within the subdivision. Such locations and dimensions shown on the plat shall 10 Ie I I I I I I I Ie I I I I I I I Ie I be given in sufficient detail to show compliance with the requirements of the Ordinance and with the provisions of the City Zoning Ordinance in respect to the size and orientation of the lots as required by the zoning of the subject tract. 4. Names of contiguous subdivisions and the plat layout of such su b divisions. 5. The current zoning of the proposed subdivision and all adjacent tracts and/or subdivisions surrounding the proposed subdivision. 6. Lot sizes and dimensions shall be given in suff:f.cient detail to verify compliance with the specif:ic requirements of the Zoning District(s) on the property. 7. Description, by metes and bounds, of the subdivision boundary and locate the tract to be subdivided on a location map at a scale of 1"- 1,000' or I" ... 2000', which shall show the existing subdivisions, streets, easements, rights-of-way, parks and public faci11ties in the vicinity. The proposed subdivision boundary Unes shall be delineated on the Preliminary Plat in heavy lines to provide a differentiation as to the area proposed for platting. The acreage of the total area of the proposed plat shall be shown prominently on the plat. 8. Existing site features of the area shall be shown as follows: (a) The location and name of all existing or recorded streets, alleys, reservations, easements or other public right of wày within the subdivision, intersecting or contiguous with its boundaries or forming such boundaries. (b) The location, and name of all existing or recorded residential lots, parks, public areas, permanent structures and other sites within or contiguous with the su b division. 9. The location and flow Une of existing water courses and drainage structures within the subdivision and/or contiguous tracts where the contiguous properties will affect the drainage design of the proposed subdivision or the drainage system of the proposed subdivision will. affect the contiguous properties. 10. Topographical information shall include contour Unes on a basis of two (2') vertical feet or less. Data from City Topo Maps will be acceptable where available. Data from USGA Quad sheet with interpertations to two (2) feet contours wm be acceptable where city topo maps nre not available. Any off-site or adjoining areas outside the limits of the area to be platted which are relevant to drainage shall have similar topography or otherwise shall be level surveyed to give reasonable verification of the limits of such off-site drainage areas, and all such off-site drainage areas shall be shown on the drainage plan. The datum for all topography shall be that of the United States Coast and Geodetic Survey, City of North Richland H:ills datum or other recognized datum source as approved by the City, with contours 11 I' I . e I I I I I I I Ie I I I I I I I Ie I developed from field level surveys or from approved aerial photogrammetric interpretation of contours based on the proper control data. Topography shall be sufficiently detailed to establish all drainage areas (and subareas). Delineation of drainage areas and all flow arrows shown should represent flow pattern of runoff after all proposed improvements have been installed and all lots have been developed. Professionals with responsib:W.ty for accuracy of topograp hy shall affix their professional seal on the drainage plan along with a signed certificate of responsibility for the topography and delineation of the drainage areas. (See Example Below). I, , a Professional Engineer registered in the State of Texas, have prepared this drainage study in compliance with the latest published requirements and criteria of the City of North Richland Hills, and have verified that the topographic information used in this study is in compliance with said requirements and is otherwise suitable for developing this workable overall Plan of Drainage which can be implemented through proper subsequent detailed construction planning. SIGNATURE , P. E., SEAL 11. A number or letter to identify each lot or tract and each block. 12. A developer desiring to submit a Final Plat- for any parcel or tract of land, must first submit a Preliminary Plat of all contiguous lands owned by him or under interlocking ownership within which the tract proposed for final platting is located.

GENERAL The criteria herein provided shall govern the design of stonn drainage improvements wi thin the Ci ty of North Richland Hills. Improvements shall include streets, alleys, stonn sewers, channels , culverts, bridges, swales, and any other facili ty through which storm water flows. All drainage improvements shall be consmlcted in accordance with City specifications and be in dedicated ReM, drainage easement or floodway easement. The developer shall provide all the necessary easeœnt and RCM required for drainage structures, including stonn sewers and open channels with access ramps. Easement width for stonn se'Wer 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 with tw\=nty (20') feet on each side to se:rve as access ways for maintenance purposes. The Developer shall be required to install at his own expense all storm sewers and drainage structures. This policy is applicable to all drainage facilities including the ma.in channels and tributaries 'of Mackey, Calloway I Walker, Li ttle Bear and Mesquite Branch Creeks, but exceptmg Big Fossil Creek. The Developer shall be responsible for excavation and full concrete channel liner improvements based on the fully urbanized one hundred (100) year frequency discharge for the channel, unless othe:rwise approved by the City Council. I, Ie I I I I I I I Ie I I I I I I I Ie I B. BASIS OF DESIGN 1. Rational Method: The method of calculation for stann runoff for drainage areas less than seven hundred fifty (750) acres will be the Rational Method. The method is expressed by the following equation: Q=CIA Q = stonn discharge at the design point in cubic feet per second. C = runoff coefficient repres~..nting the ratio of peak runoff to the rainfall. I = average rainfall intensi ty for the tiIœ of concentration at the design point in inches per hour. (See Figure 3) A = area contributing runoff to the point of design in acres. 2 . Unit Hydrograph Method: Peak discharges for drainage areas exceeding seven hundred fifty (750) acres shall be detennined by using the unit hydrograph method. The unit hydrograph for this method shall be developed by using the criteria as outlined in "Floc.xl-Hydrograph Analysis and Canputation", u.s. Army Corps of Engineers, Engineering and Design Manuals, EM 110-2-1405, Washington D.C. dated August 31, 1959. Typically a unit period of fifteen (15) minutes should be used for the detennination of the unit hydrograph. In lieu of this procedure, there are several public domain micro-cat1puter programs available which will provide satisfactory results. If the Developer elects to use a cat1puter program, he should obtain prior approval fran the Director of Public tA10rks or his designated representative. 3. Runoff Coefficient: Stonn drainage improvaœnts shall be designed based on the drainage areas being fully developed. The zoning as shown on the current Ci ty Zoning ma.ps or the City's Master Land Use Plan, whichever is more restrictive, shall determine the particular coefficient value selected. The table below indicates the runoff coefficients for the different land uses. RUNOFF COEFFICIENT "c" Single Family Zoning Districts 0.55 Duplex Zoning Districts 0.60 'Ibwnhome and Garden Home Districts 0.65 Multi-family District 0.75 Commercial Districts 0.90 Industrial Districts 0.85 School, Church and Institutional Districts 0.65 Parks and Agricultural District 0.30 I, Ie I I I I I I I Ie I I I I I I I Ie I 4 . Time of Concentration: The time of concentration shall be defined as the time required for a drop of ~ter to flow fran the upper limi ts of a drainage area to the point of concentration. Times of concentration shall be calculated for all inlets, pipe junctions, and other cri tical design points in the proposed stann sewer systems. The following minimum inlet times of concentration nay be used in place of calculated times. When calculating inlet times, consider overland flow channelized at such time as the distance traveled exceeds one hundred (100') feet. TABLE V-2 Minimum Inlet Time of Concentration Type of Area Business and Conmercial Industrial Multi-family Residential Parks and Open Space Minimum of Inlet Time 10 Minutes 10 Minutes 10 Minutes 15 Minutes 20 Minutes 5. Rainfall Intensity-Duration-Frequency: The rainfall intensity- duration-frequency canpiled in Technical Paper No. 40 by the U. S. Weather Bureau, Department of Conmerce shall be utilized in computing rainfall intensity. (See Figure 3) 6. Design Storm Frequency (See Figure 2): Stonn frequency to be used in design shall be as shown in the following table: TABLE V-3 Type of Facility Stonn Sewers Streets 011 verts, Bridges, Channels, Underpasses, and Creeks Design Stonn Frequency Minimum Design Frequency 5 Years 5 Years 100 years A stonn sewer shall be designed to pick up flow fran the street when the runoff fran a five (5) year f:rquency stonn exceeds the capacity of the street to its top of curb, or the ·spread of water on a collector street does not leave one (1) traffic lane-dry, or the spread of ~later on an arterial street does not leave two (2) traffic lanes dry, whichever is the more restrictive. The catlbined capacity of the street and ReM and/or drainage easements and the storm sewer pipe shall be adequate to safely convey the runoff from a one hundred (100) year frequency stonn. I, Ie I I I I I I I Ie I I I I I I I Ie I 7. Flow in Streets: Street capacity shall be determined by utilizing Manning's equation (See Figure 4): Q = 1.486 AR2/3 S 1/2 o n Q = discharge in cubic feet per second n = Manning's roughness coefficient, use 0.016 for pavement and gutters A = cross-sectional area of flow in spuare feet R = hydraulic radius in feet So = street or gutter slope in feet per foot For parabolic crown streets, the cross slope shall :be represented by the following formula: w 2 c y 4CX2 y =~ All discharge of runoff from street to an opem chammel shall be in a flume or through an inlet with adjoining pipe and headwall. B. Storm Drain Inlets: The capacity of a depressed curb inlet on grade will be based on the following equation: ql = 0.7 [;a1 1 H2~ ~1)5/2 - (H2)5/2 I ql = discharge into inlet per foot of inlet opening in c.f.s./ft. Hl H2 Y o = a + Y o = a = gutter depression in feet ~ = depth of flow in approach gutter in feet The capacity of low point or drop inlets will be determined based on the broadcrested weir formula: ql = 3.0 (H1)3/2 I, I . e I I I I I I I Ie I I I I I I I Ie I 9. Stonn Sewer Sxstems: Stonn sewers sha11 be designed using the continuity equation and Manning1s equation.

Addi tional lining height ma.y be required in areas of supercritical fl~l or superelevation. In cases where the top of channel liner must be constnlcted above natural ground level as required to fully contain the one hunàred (100) year flow, and where constnlction of levees or be:rms are permitted, provision shall be made for draining the local runoff which ponds behind the levees after the water surface in the channel recedes. Finished floor elevations niay be established at least 1.5 feet above the peak one hundred (100) year ~7ater surface wmch ponds behind the levees, if approved by the Director of Public WOrks.

Effect of the developnent' s drainage design on downstream properties and adjacent properties shall be given proper consideration. Water concentrated in streets, pipes, drains, culverts, and channels will be IOOved to a recognized water- course 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 frequency stonn after ultimate developnent of its watershed, or an underground storm drain with capacity for at least a five (5) year frequency stonn I· Ie I I I I I I I Ie I I I I I I I Ie I plus overland relief sufficient to safely discharge up to a canbined ten (10) year frequency flow (based on ultimate watershed developnent) without damage to adjacent property. Such ten (10) year capacity shall extend at least one hundred (100') feet downstream fran the point of discharge or fran the Developer's property line, whichever is the greater distance. Typical 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, strp..amg, channels, or underground stonn drains which meet the hydraulic capacity requirerœnts of a "recognized watercourse". The Developer is responsible for constructing all offsi te channelization or underground stonn drain with overland relief, required to discharge concentrated stonnwater from the low- end of his developrent to the recognized watercourse, and also to obtain all the necessary easements fran inte:rvening land owners. Calculations will be required to show that connecting offiste drainageways are capable of handling any increase in runoff due to developnent, concentration, or diversion for at least the ten (10) year stonn frequency. Any drainage or floc:x1way easements necessary due to the Developer's alteration of existing concentrated discharge locations (i.e., existing creeks, channels, or stann seværs) shall be acquired by the Developer at no cost to the City. c. Where the preliminary drainage study by the Developer indicates that additional runoff fran the developing property shall overload downstream drainage facilities and result in hazardous conditions, the City may withhold approval of the developnent until appropriate provisions have beèn made. These provisions shall include any drainage studies or plans necessary to indicate the offsite drainage problem will be corrected by offsite drainage construction. q. When required, the Developer will furnish to the Ci ty, a "hold hannless agreement" and a "release of liability" indemnifying the City of NRH from any liabili ties due to damages caused to the downstream property owner by the discharge of stann drainage water fran the said developnent.

Poles must be approved by a public electric utility holding a City franchise and the Director of Public Works. 2 . Poles shall be contracted and paid for by the Developer during the construction phase of a subdivision and before building penni ts are issued. 3 . Poles not purchased through a public electric utili ty holding a City franchise, shall be certified in writing by an engineer to meet the specifications as required by a public electric utility holding a City franchise. B. IœATION The location of street lights shall be as follows: 1. At all intersections. 2 . Where a new street intersects an old street. 3 . Where a block is six hundred (600') feet or longer a street light shall be installed every six hundred (600 ') feet or mid- block whichever is the shortest distance. 4. If more than one mid-block light is required, they shall be installed to create an equal lxtlance of light throughout the entire length of the block. 5. If a cul-de-sac block is four hundred (400') feet or longer, a street light shall be installed in the end of the cul-de-sac. 6 . Street lights shall be installed at any other 'location as may be directed by the Director of Public Works for the welfare and safety of the cœmuni ty . Ie I I I I I I I Ie I I I I I I I .

Council approved a contract with Rone Engineers, Inc. on November 11, 1988 for the raroval, testing, backfill, and disposal of the underground fuel storage tanks at the old Public Works service center si te on Rufe Snow Drive at Mackey Creek. The proposal £ran Rone Engineers, Inc. was for $11,650 and was based on two (2) tanks and not the four (4) tanks that were found and raroved. Also, sate fluid was still in the bottan of the tanks and it had to be pumped out and disposed of as if it were ·pure gasoline or diesel fuel. Due to sane leakage of fuel fran the tanks prior to raroval, addi tional samples had to be taken and tested. The current invoice we received fran Rone Engineers, Ine. covers all the addi tional costs to date. The total to date cost is $20,659.46. Further sampling of the tank pit trench walls will be necessary due to the leakage. If the samples show no appreciable levels of Total Petroleum Hydrocarbons ('!'PH) approximately 18" to 24" into the walls and floor of the pits, then we will be finished and can cœ1pact the backfill and no further sampling will be necessary. If the samples still show unacceptable levels of TPH, then we will have further costs involved and will be back for approval of whatever operations and associated costs that are mandated by the Texas Water Cornnission. - I The next series of samples and material removal should not exceed $4,000. The request ~t this time is approval of an additional $13,010 for payment of current invoice and to ~over estimated sampling expenses for the next step in the State's mandated fuel tank raroval procedure.
