SECTION I GENERAL INFORMATION
Introduction
This Design Manual has been prepared to assist subdividers, developers, civil engineers, and land surveyors in the processing of maps and the design of improvement plans in the City of Lake Elsinore. This Manual is intended as a guide in providing important and necessary information for preparing and processing these documents.
It is not the intent of this manual to anticipate a ll possible situations that may arise during the development process. Therefore, the standards and criteria developed within this Manual will not address every situation, but it is anticipated that the standards and criteria put forth in this Manual will apply in the majority of cases.
This Manual is divided into six (6) major sections plus the Appendix. These sections are entitled General Information, Tract and Parcel Maps, Grading Plans, Improvement Plans, Traffic, and Miscellaneous Items. Each section outlines the basic requirements and information that should be included as part of the plan set prior to submittal for City review. Checklists are included within each section to aid the user in plan preparation.
All improvement projects, whether public or private , shall be designed in accordance with this Design Manual. This information has been compiled to assist users in processing all plan checks efficiently, quickly, and accurately through the Ci ty. Failure to submit the minimum requirements will result in delays in the plan checking process.
Controlling Documents
The following documents have been used as the basis of the information provided within this Manual. The user should reference these documents w henever additional information is needed in the preparation of plans or calculations.
1. Subdivision Map Act: The current Subdivision Map Act takes precedence over all other documents and ordinances relative to the subdivision of land.
2. Subdivision Ordinance: The City Code expands, de lineates, and regulates those items that the Subdivision Map Act allows the local jurisdiction to regulate.
3. Grading Ordinance: City of Lake Elsinore Ordinances 801, 882, 1021, and this manual shall govern grading, erosion control, and plan preparation of grading plans.
4. City of Lake Elsinore Standard Plans, including latest revisions.
5. Riverside County Hydrology Manual: All hydrologi c calculations done in the City of Lake Elsinore should be done using the methods outlined in this Hydrology Manual. Computer programs may be used to assist the user in preparation of calculation runoffs and hydraulic data for submittal.
6. Riverside County Flood Control and Water Conservation District Design Manual Standard Drawings: All flood control devices should be referenced to the standards and information within these drawings.
7. Other documents referred to within this Manual i nclude the following:
• Standard Specifications for Public Works Construct ion (Latest Edition) DRAFT
• State of California, Department of Transportation, Standard Plans and Standard Specifications (Latest Edition)
• California Building Code (Latest Edition)
• International Building Code (Latest Edition)
• California Manual on Uniform Traffic Control Device s (CA MUTCD) (Latest Edition)
• Federal MUTCD (latest Edition)
Definitions
The definitions listed in this section are in addit ion to those listed in the Subdivision Map Act and the Subdivision Ordinance.
1. Legal Lot: Is a parcel established or set forth by one of the following means:
a. A deed describing the property recorded prior to March 4, 1972.
b. A recorded subdivision map or parcel map.
c. Either of the above combined with a City approve d and recorded boundary adjustment plat.
NOTE: A parcel is not necessarily a legal parcel ju st because there is an Assessor’s parcel number assigned to it.
2. Tentative Map: The tentative subdivision or parc el map is an official submittal depicting the overall development contemplated. Upon approval by the City, the tentative subdivision (parcel) map constitutes an agreement between the developer and the City.
3. Final Map: Is a map that delineates the boundary of the subdivision by bearings and distances, indicating the procedure of survey, and establishes the boundary of each lot within the subdivision.
Plan Submittal Check Lists
The following sections include check lists that sho uld be used in verifying that the submittal is a complete package in order to avoid delays in the checking procedure.
Reminder: Failure to submit the minimum requirement s will result in delays in the plan checking process.

SECTION II PARCEL AND SUBDIVISION MAPS
Parcel Maps
A parcel map procedure is used to create a division or consolidation of land under the provisions of the Subdivision Map Act and the Subdivision Ordinance. Both a tentative parcel map and a final parcel map are required. However, under some circum stances, the requirements for a tentative parcel map may be waived by the Planning Manager an d the City Engineer, who have joint responsibility for the processing and approval of t entative parcel maps. A tentative map shows existing topography, boundaries, and improvements (100 ft. beyond the project boundary including driveways, etc., located across the street from the project) plus any proposed changes. An example of when the requirement to submit a tentati ve parcel map might be waived would be when all public improvements have already been inst alled, no grading is proposed, and the only changes proposed are changes to lot line or boundar ies. The City Engineer shall determine if a tentative parcel map will be waived. If waived, a l etter from the City Engineer placing conditions on the subdivision will be sent to the subdivider i n the same manner as if conditionally approving a tentative parcel map.
The following shall apply to all Parcel Maps:
1. Parcels. All parcels created or divided by parcel maps shall conform to City standards and no existing building or structure shall be made non - conforming with respect to yard or other zoning requirements by the process.
2. Easements. No existing easement in favor of the public shall be rendered impractical by the creation of a parcel on any parcel map.
3. Improvements. The design and construction of required improvements shall conform to the criteria and standards contained in this Manual and dictated by local ordinance.
4. Improvement Agreement/Security Instruments. A parce l map improvement agreement similar to a subdivision improvement agreement may be required for improvements in conjunction with parcel maps. Said agreements, alon g with security instruments, shall be fully executed prior to recordation of parcel map.
5. Final parcel maps shall be prepared either by a registered Civil Engineer with a license number of 33965 or less or a licensed land surveyor.

SUBDIVISION MAPS
Tentative Maps
The tentative subdivision map is made for the purpo se of depicting the overall development contemplated. While not precise in detail, such as pavement structural section, it is specific in those items which can be predetermined such as stre et dimensions and right-of-way. Upon approval by the City, the tentative subdivision map constitutes an agreement between the developer and the City relative to approximate subd ivision design to include its grading, zoning, and public improvements. All subsequent work by the developer and his engineer is based on the understanding reached at the tentative map stage. The tentative map should be as complete and specific as reasonably possible.
The tentative map is filed with the Planning Depart ment and reviewed by both the Planning Commission and the City Council. The Commission acts in the capacity of an advisory body to the Council.
The following checklist provides an outline of the information required on the tentative map. All fees specified by the current fee schedule shall be paid at the time of filing a tentative map.

Street Design Criteria
1. General
The guidelines, criteria, and standards listed in T able B should be considered to be the minimum design standards for street improvements. M inimum horizontal curves are per Caltrans sight distance requirements.
a. Vertical curve design requirements are:
1) Wherever the grade break exceeds 0.5%
2) Vertical curves shall have the following minimum lengths
i. Local Street – 50 feet
ii. Collectors – 100 feet
iii. Major Arterials – 200 feet
Exceptions can be considered if dictated by adverse topographic or environmental conditions. Exceptions shall be approved by the City Engineer.
2. Miscellaneous Design Criteria
a. When a raised median with landscaping is require d, the design will indicate all proposed median openings and turning pockets and shall also be approved by the Traffic Engineer.
b. General criteria for lengths of left turn pocket s:
1) Estimate the peak hour left turn movements.
2) Design pockets shall provide for a minimum of tw enty feet (20’) length for each car desiring to turn left during peak hour or the minimum length shall be three hundred feet (300’) for major or urban arterial roads, two hundred fifty feet (250’) of secondary or collector streets, and one hundred fifty feet (150’) for all local streets.
3) If left turn movements are unknown or cannot be accurately predicted, the following guidelines may be used: (1) Pocket lengths should b e increased if there is known to be greater than “average” truck traffic; (2) Turning volumes exceeding fifteen (15) cars per cycle should be accommodated by multiple l eft turn lanes; (3) Physical obstructions in the roadway should be designated wi th turning radius to accommodate larger vehicles.
4) Pavement widening and tapers will be required as determined by the Traffic Engineer.
These may occur when the tract development does not require ultimate improvements to an adjacent arterial, but the traff ic generated by the tract could cause significant congestion on the arterial. In th ese cases, pavement widening may be required for acceleration or deceleration or for left turn lanes.
DRAFT
For narrowing the travel lanes, the minimum transit ion rate should be 40 to 1. For widening the pavement, the transition should be app roximately 10 to 1. Any proposed pavement widening and tapers should be rev iewed by the Traffic Engineer.
c. Permanent barricades will be used whenever a str eet dead ends without a cul-de-sac.
3. General criteria for the location of access poin ts.
a. Refer to Intersection Intervals of City Standard Plan No. 100A of Roadway Design Requirements.
b. The tentative map review should show all existin g and proposed access within the tract limits and in some cases an area access plan may be required by the Traffic Engineer.
c. Access points should be selected at points with the best possible sight distance and all access points shall provide adequate sight distance.
d. If it is determined that a signal will be necess ary to service the development, the location to be signalized shall be at least ¼ mile from adjacent signals. The Traffic Engineer should review and approve the signal location.
e. Adjacent intersections along the same arterial s hall be spaced sufficiently apart to provide for left turn pockets for both streets. Thi s usually requires a minimum of 660 feet.
f. Extreme care is needed in locating driveways to avoid possible left turn conflicts where no raised medians exist.
g. Adjacent intersections along the arterial, but o n opposite sides and offset in a direction in which left turns will not be in conflict, should be avoided.
h. Standard cul-de-sacs are required for all perman ent dead-end streets and may be required for temporary dead-end streets if future development seems remote. The maximum lengths of cul-de-sacs shall not exceed 660 feet.
i. Private Streets.
1) Definition:
(a) Private streets are those streets which are privately owned and maintained and are not offered for dedication to the City. They ar e allowed only if adequate justification is provided.
(b) Design standards for private streets are consid ered to be the same as public streets regarding volume capacities and geometric design features and shall be designed to the same criteria. The absence of such standards will prohibit future dedication to the City for ownership or maintenance.
j. Driveways.
1) Driveways which exceed centerline measurement of thirty feet (30’) in length measured from the location of the face of curb, sha ll be provided ahead of each DRAFT
garage, a parking space shall extend a minimum of t wenty feet (20’) out from the face of the garage and shall be at least the width for the garage opening with a minimum of ten feet (10’), shall have longitudinal and transverse slope gradients not exceeding plus or minus five percent (5% +/-) and shall be designed to prevent surface waters from draining into garage.
2) Driveways which do not exceed thirty feet (30’) in length measured along the centerline shall have a maximum gradient of eight p ercent (8%) for the portion of the driveway located within twenty feet (20’) of the garage entrance;
3) Maximum longitudinal driveway gradients shall be fifteen percent (15%); minimum crown or cross slope shall be one percent (1%); and maximum crown or cross slope shall be five percent (5%).
4) Vertical transitions shall prevent contact of an y portion of the car with surface of driveway by use of the following criteria:
(a) Vertical transition shall be made with not less than four feet parabolic curve.
(b) When the driveway exceeds ten percent (10%), th e vertical transition shall be an eight foot (8’) parabolic curve.
