This report is required by the City of Fontana to insure that the effect of increased runoff is properly mitigated. EXISTING SITE The elementary school site is located on the west side of Mango Avenue between Baseline Road and Miller Avenue in the City of Fontana. The site is approximately 10 acres bounded by the Mango Avenue centerline to the east and undeveloped grassy fields to the north and west. The existing site drains to the south. The onsite drainage area consists of various grasses growing in the open and on piles of end-dumped fill. PROPOSED CONSTRUCTION The site plan proposes to construct a minimum of seven permanent classroom structures and about four acres of impervious area for parking, roofing, sidewalks, play areas, and fire lanes. The balance of the onsite area is for landscaping and turf playfield areas. Most of the site will drain to a detention structure in the southwest corner of the site. Hydraulic structures will be designed to achieve the following objectives: 1. Area drains to prevent inundation of the finished floors in the 100-year, 3-hour event. 2. Pipes to convey the 100-year, 3-hour event to the detention structure. 3. A detention basin with an outflow structure which reduces and delays the peak outflow and meets the criteria of the City of Fontana. 4. An emergency escape which allows the 1000-year runoff to exit the basin without damage to the adjacent downstream property. HYDROLOGIC METHOD The following was used to develop the design criteria and design method for this report: 1. 1986 San Bernardino County Hydrology Manual, Sections E & F. 2. Detention Basin Design Criteria for City of Fontana. 3 Mango School Design Criteria per meeting on May 2, 1991. Section J of the Hydrology Manual was not used because it was assumed that a 5-minute unit time will be sufficient to describe the detention basin inflow hydrographs. The portion of the site tributary to the basin was taken to be one tributary area because the sub-areas would be too small if the site was divided further. INITIAL TIME OF CONCENTMATION The initial time of concentration was determined from Figure D-1 of the San Bernardino County Hydrology Manual. For the undeveloped case, a flow path (L) of 700 feet and a vertical drop (M) of 13 feet yield a Tc of 11.8 min. When corrected, this results in a Tc' Of 28 min. (at good cover). This results in a conservatively large Tc' (conservative because it results in the least flow for comparison with the developed case). For the developed case, a flow path (L) of 725 feet and a vertical drop (H) of 8 feet yield a Tc of 13.4 min. When corrected, this results in a Tc' of 10 min. (at commercial cover). This results in a conservatively small Tc' (conservative because it results in the greatest flow for comparison with the undeveloped case). See Page 3.0-7 for the determination of Tc'. DESIGN FOR OFFSITE FLOWS Per Felipe Molinos, we are providing a design to intercept the estimated offsite flows until the parcel to the north develops. We are using the following simplified procedure: 1. We are using 1 CFS per acre as a flow rate which approximates a 25-year event for the offsite tributary area of 6 acres. 2. Structures will be designed to intercept and transmit this flow at the normal depth. 3. The consequences of failure are that the parking lot may be flooded and the offsite flows may get into the detention basin which is oversized due to other design constraints anyway. 1.02 RESULTS The developed hydrographs were routed through a 3 acre-foot detention basin using the modified PULS method. A 1-foot diameter orifice provided the required flow reduction. Most events will be substantially over-mitigated because the 2-year event governs the orifice size when only one orifice is provided. In the 100-year event, only 0.67 acre-feet of the basin is actually used as the water ponds 2.5 feet deep with a maximum outflow of 5.2 cfs.

Wolf/Lang/Christophe= Archer' 10470 Foothill Blvd. Rancho Cucamonga, CA 91730 Subject: Public Improvements in Rancho Fontana Dear Mr. Kuehl: Thank you for attending the recent meeting to discuss the City's requirements for public improvements required as par~ of the construction of the Hemlock Elementar~ School, the - Mango ElementarT School, and the Presley residential and Public Works Engineering staff met to review each of the requirements and to develop a formal City staff position. The balance of this letter explains each public improvement requirement and the Justification for the requirement. In those cases where the public improvement benefits your development and future adjacent developments, the City is willing to prepare and execute a Reimbursement Agreement. The provisions of the Reimbursement Agreement will charge future adjacent developments, when those developments are ready to commence, for their fair share of the public improvement costs. Then, their fair share of the public improvement colts will be disbursed to you. Hemlock ElementsTY SchOOl 1. Street Paving on Miller Avenue South of the School - We i are requiring the school distr c~ to install foray-four foot wide street paving on Miller Avenue ands twelve foot wide parkway on the north side of the street. These improvements are required for the portion of Miller Avenue directly sCuth of the school, from Snll~irlgon to Hemlock. ~his street improvement is consistent with City p01icT, 8353 GIEBI~ AVENUE(P.O. 80X 5~8) · FONTANA, CAL.IFOBNIAe~334-O618 · (714)380,7G00 and it meets the General Plan requirements for Miller Avenue, which is designated as a collector street. 2. Paved Knuckle on Snapdragon and Miller - We are requiring the school district to install a paved 'knuckle at the Junction of Snapdragon and Miller (on the south side of Miller). This is a standard requirement for street improvements, which applies to this type of street Junction. 3. Stor~l Drainage on Miller - We are requiring the school district to extend the storm drainage facilities along Miller to the east property line on Hemlock Avenue. As a matter Of City policy, we require all developments to mitigate additional storm run-off resulting from the development. We would be receptive to considering and evaluating Other hydrologic engineering solutions to meet the City's drainage mitigation r, iremont. 4. Sanitary Sewer Line - We are requi~ing the sch~oi district to extend the sanitary sewer line along Miller to its east property line on Hemlock Avenue. Like the city policy on storm drainage, City policy requires all developments to provide sanitary sewer lines and hook-ups to handle the sewage resulting from the development. 5. Related Design Issue - We are requiring Presley to pave Hemlock Avenue along the easterly edge of the school site. This may affect the Hemlock School by making it necessary to redssign the entrance for the school. Manqo Elementary School 1. On-Site Detention Basins - We are requiring on-site detention basins to detain storm run-off. We regrat any previous communications ~bout not needing on-site detention basins. we have carefully re-evaluated the hydrologic conditions of the area and the probability that the City of Rialto will construct drainage facilities in the nex~ few years. We are not optimistic that Rialto's planned drainage facilities will be available when the Mango Elementary School is completed. Therefore, we have determined ~hat it would be better to use detention basins to handle ~he storm m-off. We are open to the idea of reviewing ~he school district's engineer's hydrolog~ study and working wi~h the school district to find the best solution to this issue. We would also like to receive more information about the time schedule for this project. Preslev Residential Development 1. Street Paving on Miller - We are requiring the Presley to install forty-four feet wide street paving and a twelve 2 foot wide parkway on Miller Avenue where the Prostoy tract is adjacent tO Miller. The parkway should be on ~he north side of the street paving. To link Miller between Hemlock and the paving on Miller adjacent to the Proslay tract, we are requiring thirty-six feet wide paving. These street improvements are consistent with City policy, and they meet the General Plan requirements for Miller Avenue, which is designated as a collector street. 2. Storm Drainage on Miller - We are requiring Presley to extend the storm drainage facilities along Miller to the east property line. As a matter of City policy, we require all developments to mitigate additional storm run-off resulting from the development. We would be receptive to considering and evaluating other hydrologic engineering solutions to meet the City's drainage mitigation requirement. 3. Sanitary Sewer Line - We are requiring ?Joelay to extend the sanitary sewer line along Miller to the east property line. Like the City policy on storm drainage, City policy requires all developments to provide sanitary sewer lines and hook-ups to handle the sewage resulting from the development. 4. Secondary Access for Proslay Tract - We are requiring proslay to install paving for a secondary access route on Hemlock. The City already has a seventy foot wide right-of-way to make Hemlock a through street from Miller Avenue to the Proslay tract. This secondary access route~ is necessary to enable ingress and egress to interior lots by emergency police, fire, and paremedic vehicles. Additionally, City policy requires secondary access to residential tracts with more than twenty interior lots. As required by the Rancho Fontand Specific Plan for local streets, (attached) this street improvement for Hemlock must~fifty feet wide. The pavement should be along the easterly edge of the seventy foot right-of-way. 5. Secondary Access for the Area - We are requiring Proslay to install approximately seven-hundred feet of street paving on Miller from the easterly edge of the Proslay proper~y east ~hTOUgh the right angle Junction with Beech and northerly on Beech to Sandhurst. The paving must he thir~y-eix feet wide, which is the minimum street width permitted by City policy. These street'improvements are ne~essar~ in order to provide secondary access to the school, ~he Proslay residential development, and the adjacent areas. If Proslay makes a good faith effort to acquire the property rights for the thirty-six feet wide secondary access route and is unable to make the necessary acquistion, the City may assist Proslay by commencing eminent domain proceedings. 3 We hope this let=er helps to clarify our issues you raised. If you would like to discuss anv of the issues in greater de=all, would we be pleased to meet wi h you. Sincerely Davi .

We received these plans for first check on June 8, 1989. The City sent these plans to us in one package with one common plan check fee. Therefore, one work order was opened for the plan check of these three schools. 2. Since only one work order was opened and due to the length of time (almost 3 years) that has transpired since first check, it is difficult to allocate work effort to each school on an individual basis. 3. I3Jy_ould appear that a substantial portion of the plan check costs are 1 h atlribUial~ to the Mango Scool since over the two andone-half year time period, from first check to recommendation for approval, it went through nine plan checks. Our plan check records concerning Mango School are attached. 4. Referring to the attached plan check dates, please note the following: Ph Nine (9) months elapsed between first and second checks. Any time a considerable time period elapses between plan checks the efficiency of the plan checker is diminished sinc~ tht~y must cotnpletely refamilarize themselves with the project again. B. Fourteen (14) months elapsed between fourth and fifth plan checks once again decreasing efficiency. C. It should be noted that the first time and materials invoice did not occur until October 17, 1991. Hence, as much Wbrk effort as possible was expended under the original plan check fee. 5. Please note that the later submittal of the storm drain plans yielded plans and hydrologic/hydraulic calculations that were completely revised, hence effectively placing the plans into a "first cheek mode". 6. Please refer to our previous letters (attached) to the City dated December 31, 1991 and January 27, 1992 that provides additional information. 89-1117D/lit CIVIL ENGINEERING PLANNING ENVIRONMENTAL ANALYSIS SURVEYING ASSESSMENT/SPECIAI~ TAX ENGINEERING Ms. Grace Maninez March 13, 1992 Page 2 We hope this information will allow our outstanding invoices for this project to be processed.

Mango Avenue School . - .... De~r Mr. Cota: Attached are the original mylurs for the street and storm drain improvement plans, along with two copies of the onsite hydrology study for the referenced project. We have reviewed these plans and calculations and recommend final review and approval by the City. Please note that we did not review the structural calculations and soils report as it appears to be a City of Forttans Building and Safety Depa~ tment's function. Corrections have been made in response to Traffic Engineering and Operation Departments request. it is also our understanding that the City of Fontaria is currently reviewing and processing the legal documents necessary for additional street R-O-W dedication for this project. It is also our recommendation that construction easement(s) are obtained for the installation of the storm drain pipe as shown on Sheet 2 of 2 of the storm drain plans. Due to the fact that the storm drain plans and calculations were completely revised, and additional time was expended to insure that comments from the Traffic and Operation Departments were made, additional time and material charges were encountered. Further, two meetings were requested by the City to discuss the plan check comments. As such, the additional $1,500.00 deposit requested on July 15, 1991 has been exceeded. Pursuant to Anthony Manzano's December 4, 1991 discussion with you, we were instructed to provide a final billing with this plan check. As our invoices am typically 30 days behind the actual time period when the work was performed, and since it is difficult to determine the exact cost required to complete the plan check, it was resolved that Webb Associates would provide the City an estimated deposit to cover additional time and material plan check costs. We recommend that the City collect an additional $1,600.00 as a deposit to cover the additional time and material charges. Upon completion of the checking for this project, the mount of this deposit that remains after our invoicing is complete, can be refunded back to the Developer.

Corrugedo BL Engineering, Inc. 2311Hyperion Avenue Los Angeles, CA 90027 RE: Hydrol ogy Study and Calculation for Hemlock Avenue Elementary School Dear Nr. Corrugedo: A review by City staff of the above subject hydrology study and calculations has determined that said study is not in agreement with a more detailed hydrology study completed for Tract No. 13926. Said tract is located north of ~iller Avenue between Beech and Hemlock Avenues, immediately upstream of the proposed Hemlock Elementary School site. The hydrology study for Tract No. 13926 presents a detailed layout of the streets and plot plan for the proposed development. It is the Ctty's opinion that said study more precisely addresses the ultimate drainage conditions to be expected, as well as the runoff and confluence details. It is therefore reconm~ended that BL Engineering incorporate the hydrology study for Tract No. 13926 as prepared by Radole & Associates, Inc,, 1820 East 16th Street, Santa And, California 92701. A copy of said Tract No. 13926 hydrology is available for your review at the City offices, Sincerely, Richard Cote Principal Civil Engineer cc: Ron Kuehl WLC Architects, Inc. 10470 Foothill Blvd. Rancho Cucamonga, CA 91730 RC:ke 8353 SIERRA AVENUE (P.O.
